How to avoid peeling of epoxy floor?

How to avoid peeling of epoxy floor

1. first, the ground foundation is qualified, the strength is up to standard, no empty black bean, dry and no return water. It is better to have water separation treatment below.

2. ground treatment, carefully polish, pay attention to hollowing, ash and the places to be shed must be cleaned. The cracks on the ground should be cut carefully.

3. epoxy primer with strong permeability must be used for primer application, and it should be evenly applied. Pay attention to the defective ground (such as the place where the concrete fails to meet the standards) must be handled with emphasis.

4. the mortar in scraping must improve the resin content (more than 75% of epoxy resin content) too low and easy to powder and fall off. Most of the peeling is caused by reducing the resin content in the compression cost. The cracks, cracks and the ground where there are defects must be repaired with epoxy resin and sand (quartz sand below 80), and do not use powder (more than 180) otherwise it will easily crack and cause failure of repair. (the principle of using stone instead of fine sand is necessary for concrete beating).

5. avoid winter construction as far as possible without heating (if necessary, it is recommended to make special treatment for expansion joints).

What’s the difference between wear-resistant floor and curing agent floor?

Grinding floor is also called wear-resistant aggregate floor, which is divided into metal mold (emery wear-resistant floor) and non-metal wear-resistant floor. It is to spread a layer of emery aggregate on the surface after concrete pouring to enhance the wear resistance.

Curing floor, also known as hardening floor, is a kind of concrete sealing and curing agent that penetrates into the concrete and changes the internal structure of concrete through the reaction of materials, so as to increase the hardness and gloss. There are also great differences between the two construction processes. Wear resistant floor: during the construction, the wear-resistant aggregate is completely penetrated into the concrete surface, and the construction is synchronous with the concrete construction. After the completion of the construction and concrete integration, the final product is the appearance of concrete. Compared with ordinary concrete floor, wear-resistant floor has higher hardness, and is less prone to weathering, pulverization, oxidation, rough surface, easy to dust, acid and alkali resistance, oil pollution resistance and other problems.

Concrete sealing curing agent floor: during construction, the concrete must be completely solidified before construction, and the concrete must be completely dry before construction. Generally, the curing agent is constructed after about 20 days of curing after concrete construction. The curing agent completely penetrates into the concrete and integrates with the concrete, and the final product is also the original appearance of the concrete. But at this time, the concrete has formed a dense whole, which is resistant to penetration, compression, wear resistance, acid and alkali corrosion, no ash, no maintenance and maintenance. The biggest difference is that it can be solidified on the wear-resistant floor, with better effect and longer service life. And solidified floor is not (let alone) to do wear-resistant floor.

Can common epoxy resin floor be used outdoors?

We can often see a lot of beautiful epoxy floor from indoors. When epoxy floor paint is applied outdoors, many customers begin to complain about the poor effect of epoxy floor paint. In fact, it’s not that the epoxy floor paint is not good, but that the construction of epoxy floor paint outdoors is affected by environmental factors, Another part of the influence comes from the improper selection of epoxy floor coating materials and improper construction design. Therefore, the customers have a wrong understanding of epoxy floor coatings.

The reasons why epoxy floor coatings are not suitable for outdoor display are as follows:

1. The weather resistance of epoxy floor paint is poor, because the epoxy resin is composed of at least two epoxy groups, and the epoxy chain is easy to break under the ultraviolet light for a long time, resulting in the surface fracture, delamination, differentiation and other lesions of the epoxy floor. Therefore, many epoxy floor coatings can not be well displayed outdoors.

2. Epoxy floor paint itself has outstanding functionality, it has excellent pressure resistance, anti-corrosion and other functions, the most outstanding is its excellent adhesion to metal materials. Epoxy floor paint applied to the interior is the best way to show.

3. Although the epoxy floor paint has practical functions, the curing time of the epoxy floor paint is long, and the construction of the epoxy floor in the outdoor will be affected by the outside world, and can not get a good effect（ For example, the wind is easy to cause the debris falling from the top coat before curing to adhere to the top coat, which will affect the beauty. High temperature in summer, direct sunlight, unpredictable thunderstorm, etc. will affect the film-forming property of the top coat). Moreover, the epoxy floor has poor weather resistance and is easy to color change under ultraviolet radiation.

Conclusion: epoxy floor coatings are not completely unable to be applied outdoors. There is an acrylic or modified polyurethane epoxy floor coatings, which has the characteristics of UV resistance and is more suitable for outdoor application. Finally, we also need the epoxy floor paint construction team to provide professional construction scheme, so as to ensure that the epoxy floor paint has a better display effect.

What is epoxy floor?

Epoxy floor, fully known as epoxy resin floor, is a new functional floor made of epoxy resin as binder, some aggregates and fillers such as calcium bicarbonate powder, quartz sand, etc. and curing agent. Epoxy floor is a kind of floor product with excellent decoration and function. It belongs to coating class and is a kind of high-quality product. It has color and high-strength coating property.

The higher the thickness is, the higher the quotation will be. It will not eliminate the phenomenon of more than 100 or even 200 or more.

c. Simple epoxy flat coating: the intermediate coating sand scraping procedure is omitted, and even some even have no intermediate coating putty layer, so the quotation is extremely low, generally around 25 yuan / m2, and some even as low as 18 yuan / m2. But one price one goods, this type of floor although the price is low, but the use cycle is also very short, not a long-term solution. d. Epoxy skid Lane: for underground garage, the thickness is not less than 3mm. According to the request, the general quotation is 120 yuan to 180 yuan / m2.

e. Anti static epoxy floor: there are two types: flat coating type and self leveling type, but the anti-static ability of flat coating type is poor, so it is not mentioned here. The market quotation of standard and above self leveling anti-static floor is generally no less than 120 yuan / m2.

f. Color sand epoxy floor / floating sand epoxy floor: it belongs to the high-strength wear-resistant epoxy resin floor with special decoration effect, with high standard level and high price, which is more than 150 yuan / m2.

g. Quotation of water-based epoxy floor: the self leveling skill of water-based epoxy floor is not perfect, but the mortar flat coating type has been used skillfully. Under the same specification, it is slightly higher than solvent type and solvent-free type, that is, the unit price is between 30 and 100 yuan / m2.

5. Is epoxy floor oil proof? For general engine oil, gear oil and other anti-seepage effect.

6. Is epoxy floor acid and alkali resistant? Resistant to slight acid and alkali, not too long. There is a special epoxy anti-corrosion floor.

7. Can epoxy floor be used outdoors? Generally not recommended for outdoor use, primer and topcoat can choose better weather resistance.

8. Is epoxy floor toxic? Epoxy materials contain toxic substances, but after curing, epoxy floor is generally harmless to human body.

How to build large area super flat floor?

The flatness of the ground is one of the standards to measure the quality of the floor project, which has a great impact on the use of the ground. If the ground is flat, it will cause a lot of trouble to people ‘. Therefore, it is necessary to create a super flat floor, and the good flatness of the ground is also conducive to the construction of the floor, and the better the ground effect.

So how to create super flat floor in floor construction?

1. The construction personnel are professional in technology and rich in experience. They can operate and control the floor grinder well, which is more conducive to building the flatness of the ground.

2. With the use of the floor grinder, the intelligent floor grinding technology can freely adjust the walking speed and speed, and different operators can also achieve the same grinding effect, so as to avoid the floor grinder grinding a deep and shallow ground under the subjective influence of human.

3. The use of floor detection tools – guiding rule, feeler, guiding rule and feeler can be used together to measure the flatness of the ground. They can be used to measure the ground before and during construction, so as to know which floor grinder should grind the ground lower and where it should grind higher.

In the process of creating super flat floor, pay more attention, so that the flatness of the ground will be better and better.

9. Safety requirements if the floor is in the oil environment or on the ramp, it is necessary to choose the anti-skid floor; If in gas stations, oil depots and other special places need to choose anti-static, explosion-proof.

How to deal with the aging, ash and sand of cement floor?

In factories, especially in machinery factories, when forklifts drive back and forth, the ground is often subject to friction or impact by external forces, as well as erosion by chemicals and oil. In addition, the service life of cement ground is relatively short. Under the effect of aging and weathering, many problems such as ash and sand, tarnishing, hollowing, cracks, holes, damage and so on quickly appear on the cement ground, It is necessary to take curing construction technology for grinding and curing in time.

Floor solidification is a dust-free ground construction technology, which can solve the problem of dust and sand on the ground and create a dust-free and healthy working environment. Its main floor material is concrete curing agent, which reacts with cement in concrete to produce stable chemical product (C-S-H) without expansion and shrinkage, so as to make the whole floor more compact and firm. It can also grind and polish with intelligent floor grinder to obtain a high hardness, high density and high brightness concrete curing floor, The problem of dust and sand on the ground is solved from the root. The ground is not only more wear-resistant and compression resistant, but also more durable.

The steps of cement ground treatment by solidification construction technology are as follows:

1. Base surface cleaning: clean up the ground garbage, check the ground condition, remove the expansion screw and other hard materials.

2. Rough grinding and leveling

Use the intelligent floor grinder with metal grinding plate to dry grind the ground until the concrete surface is uniform and smooth, and clean up the dust on the ground.

3. Penetration of concrete curing agent

Clean the floor with a vacuum cleaner before applying the curing agent, or clean the floor with a dust pusher, and then spray the concrete curing agent.

4. Fine grinding

After confirming that the concrete curing agent has been completely dried, the intelligent floor grinder and resin grinding plate are used for further grinding and rough polishing of the ground.

5. Fine throwing

Push the floor clean with clean dry dust, and then polish it with high-speed polishing pad, and the brightness will be higher if polishing is carried out after brushing protective agent.

How to judge the quality of a floor grinder?

Floor construction will use the mechanical equipment of floor grinder. To make a good floor, technology, theory and experience are very important. The choice of machine is also very important. Good machine is indispensable to make a good floor.

So how to judge the quality of a floor grinder?

1. Work efficiency

Working efficiency is an important index of major machinery, which is directly related to the construction cost and profit.

2. Controllability

Controllability is whether the operation process of the floor grinder is stable and whether the labor intensity of the operator is appropriate.

3. Reliability

Reliability refers to the failure rate of mechanical equipment and the stability of operation.

4. Construction results

The result of construction is whether the ground after grinding by the floor grinder is effective in flatness, glossiness and clarity

How to make the service life of floor paint longer

How to prolong the service life of floor paint: first, when epoxy floor paint is in normal use, there are economic ordinary epoxy floor paint or pressure mortar. The thickness of epoxy floor paint is 0.5mm-3.0mm, which can be used for more than three to five years. With the increase of thickness, the service life is also increasing. Secondly, due to the need of pressure, some factories often have 5 to 10 ton forklifts. Therefore, it is necessary to increase the thickness of product design. Adding quartz sand or diamond aggregate into epoxy floor coating can improve its compression and impact resistance, and effectively realize the use of the product. Third, in the aspect of anti-corrosion, such as oil pollution in machinery plants, solvents in chemical plants, all products need to meet the requirements of anti-corrosion, which requires different curing agents to improve the performance of products. Curing agents are anticorrosive, temperature resistant and low temperature curing. When anticorrosion requirements are more friendly to customers, epoxy resin should be used. Modified vinyl ester floor materials meet the special requirements. Different curing products can be selected according to the customer’s requirements, plus good epoxy resin, to achieve different technical specifications and indicators. Fourth, the factors to improve the service life of the floor coating are: the correct use of forklifts, wheelbarrows, elastic rubber wheels and other users’ correct use methods, do not scrape hard objects on the ground, add curing agent in the production process of the floor coating, use good curing agent or increase the solid content of the coating, which can effectively improve the service life and wear resistance of the product, And can solve the problem from the formula system, has the unique opinion to the formula.

Then, what preparations need to be made for the construction of solidified floor will be introduced. I hope it will be helpful to you.

Why is the application of concrete sealing and curing agent floor very popular?

With the rapid development of science and technology, solidified floor is more and more common. Why can solidified floor be deeply rooted in people’s hearts and become an indispensable part of people’s life? Today, let’s talk about the benefits of solidifying the floor to attract the masses?

First of all, what can attract the masses is its hard and wear-resistant function. The hardener reacts with the material in the ground to form a hard material, blocking the structural gap in the ground, which will greatly improve the hardening and wear resistance of the concrete surface, forming a long-term marble like protective layer, and the hardness and wear resistance can reach 6-8 degrees of Mohs.

The second is its thorough dust-proof function. Solidified floor can completely prevent dust because it combines with the salt in the ground and becomes an integral part of the ground. It has bright anti-skid function, after the curing agent out of the ground, good ground will appear charming bright anti-skid effect, and after the use of time delay, the external light of the surface is better.

Finally, its green function. Curing agent, colorless, tasteless, no organic solvent, in line with today’s environmental protection, health, safety concept, can easily improve the old, low-quality concrete surface problems, because the construction is simple, non-toxic, odorless, can be produced at the same time, construction, and can be put into use quickly.

To sum up, the concrete curing floor is a safe and environmental protection, beautiful and practical, long-term use of the ground. That’s why most owners like it. It’s everyone’s responsibility to protect the earth. It’s worth having the green solidified floor! Hurry up!!

Why do we need to do the floor project again on the concrete floor?

Some people who don’t know about the floor often ask why we need to spend money on the floor construction. When we built the factory building, we had already constructed concrete, so why do we need to make the sealing curing agent floor on it. In fact, the floor only plays a certain role in protecting the ground and providing us with some environmental protection functions that concrete can not provide. Now Tianjin comfort will give you a brief introduction of the reason.

Before we understand the importance of flooring, we need to understand the concrete that we often talk about. Concrete is made of cementitious materials, natural rocks and sand mixed with water and hardened after a period of time. According to the apparent density, concrete can be divided into heavy concrete, ordinary concrete and light concrete. The difference between these three kinds of concrete is the difference of aggregate. Although the concrete has good hardness, but the concrete itself has a lot of pores, and it also contains water and alkaline, so its wear resistance and compression resistance is relatively weak. For example, a lot of forklifts and heavy vehicles in factories and warehouses walk, so it is necessary to choose the floor to improve the hardness and strength of concrete. In addition, if the ground needs to be clean, anti-static or anti-corrosion performance, it is more necessary to choose the appropriate floor. Therefore, especially for the parking lot, factory, warehouse and other environment, it is very necessary for the industrial floor to carry out daily ground maintenance.

What is the difference between grinder and high throwing machine in floor construction?

The last several working procedures of concrete floor curing agent construction are polishing and polishing. In this working procedure, you can choose to use a grinder for polishing, or you can choose to use a high-speed polishing machine for polishing. Now that the problem has arisen, what is the difference between the two? Today Xiaokang will analyze the different performance of the two devices for you.

In the polishing stage, when the floor grinder is used for concrete curing construction, generally speaking, the floor grinder uses the fine tooth resin grinding plate for polishing. Because the rotation speed of the floor grinder is lower than that of the high-speed polishing machine, the grinding efficiency of the floor grinder will be lower, so the labor cost will be greatly increased, At the same time, the loss of grinding plate will be larger than that of high-speed polishing machine.

Because the grinding plate of the high-speed polishing machine is relatively large, the linear speed of the pad will be very high at the edge of the polishing pad, which makes the construction efficiency of the high-speed polishing machine much higher than that of the grinding opportunity in the polishing stage of concrete curing construction. At the same time, the area of the polishing pad used by the high-speed polishing machine is also more than that of the grinding pad at the same price, This also makes the cost of grinding plate get partial saving. But because the high-speed polishing machine can not be used in the ground rough grinding, it can only play a role in the later short polishing stage, so in the selection of floor grinding equipment, we need to consider the actual situation of the project, and rationally choose a better equipment for construction.

How does high speed polishing machine play its role in concrete floor?

Application technology of high speed polishing machine

1. To investigate the actual situation of the ground and consider the need to control the sanding problem, a layer of hardener material on the ground is first applied to enhance the foundation hardness of the ground;

2. The floor is renovated with 12 head heavy grinder and steel grinding plate, and the protruding part of the floor is flattened to reach the standard flatness;

3. Start rough grinding the ground, use 50 mesh – 300 mesh resin grinding plate, and then start spreading curing agent material evenly, waiting for the ground to fully absorb the material;

4. After the ground is dry, use 500 mesh resin grinding plate to grind the ground, wash the ground mud and residual curing agent materials.

5. Post polishing

1. Start to use high-speed polishing machine with No. 1 polishing pad for polishing.
2. Clean the floor, use a vacuum cleaner or dust mop to clean the floor (no need to add water to clean, mainly the residual powder of polishing pad).
3. Place the polishing liquid on the floor and wait for the floor to dry completely (according to the material requirements).
4. Scratch the ground with a sharp object, leaving no trace. Start to use polishing machine with No.2 pad for polishing.
5. Finish polishing. The effect can reach more than 80 degrees.

How to choose the floor grinder_ Drive planetary disc grinder?

The performance of the concrete floor grinder includes: grinding width, running mode of grinding head, rotation speed, unit pressure of grinding head, water quantity control, etc. The construction standards are divided into flatness, clarity and glossiness.

1. Ground grinding area: relatively speaking, the larger the grinding area of the machine, the higher the flatness of the construction ground, but it is the increase of the grinding range, which makes the leveling efficiency of the ground height difference lower.

2. Operation mode of ground grinding head: the more complex the ground grinding head operation mode, the greater the grinding force, the higher the working efficiency, and the higher the ground clarity. The grinding force of the two-way 12 grinding head floor grinder is stronger.

3. Speed of floor grinder: generally, the higher the number of grinding head turns of the ground grinder, the grinding force will also be improved. But the high speed will reduce the grinding force between abrasive and ground. When the grinding head pressure is relatively low, the stability of machine operation will be reduced, and the construction standard will be reduced.

4. Unit pressure of the grinding head of the floor grinder: the head pressure of the floor grinder is the weight of the machine. The greater the pressure of the grinding head, the higher the relative efficiency and leveling rate. If the pressure of grinding head is large and the cutting force increases, the ground grinder can not operate at a uniform speed, which will reduce the construction flatness.

5. Water quantity control: generally, grinding on the ground is divided into wet grinding and dry grinding, which mainly determines the ground. Water can be used for lubrication, chip removal and cooling. The water quantity of granite hard ground should be controlled in time with the change of grinding process. The ground grinding temperature also directly affects the grinding brightness.

Through the performance of the floor grinder, we believe that we can understand the performance of each part of the floor grinder, and then it is convenient to choose a more suitable ground grinder.

How to deal with the floor paint before using the floor grinder?

Ensure and improve the adhesion of the floor paint coating: the treated concrete base can make the floor paint primer more penetrate into the concrete surface, which plays a key role in the service life of the whole floor paint coating. Especially when there is oil and water on the base surface, it is difficult to form a continuous coating due to the poor compatibility of oil and water with the coating. Even if a complete coating is formed, the adhesion of the coating will be greatly reduced, which makes the coating fall off prematurely. When there is dust on the surface and it is directly applied without base surface care, the light may cause pockmarks on the floor paint coating, and the heavy may cause large area peeling off of the floor paint coating and shorten the service life of the floor paint. Therefore, at the same time, it is necessary to prepare for the establishment of a smooth, flat and beautiful coating, and create a good foundation for the whole floor paint project.

Create appropriate surface roughness: the adhesion of the floor paint coating on the concrete surface mainly depends on the mutual attraction between the polar molecules in the floor paint and the molecules on the surface of the substrate. The surface of concrete will become rough after being ground by the floor grinder. With the increase of roughness, the surface area also increases significantly, and the attraction between the coating and the base surface per unit area also increases exponentially. At the same time, it also provides a suitable surface shape for the adhesion of the floor paint coating, and increases the mechanical toothing effect, which is very beneficial to the adhesion of the epoxy floor paint coating.
