What should be paid attention to in the winter construction of epoxy flooring?

Attention should be paid to winter construction: first close the doors and windows, so that on the one hand, the indoor temperature can be guaranteed, and on the other hand, the outdoor wind and sand can be avoided.

When spraying various coatings, oilmen should paint in strict accordance with the temperature and humidity in the product instructions, and the temperature of the construction environment should not be lower than 5

In the solid paint process, such as the use of putty or water ash, can not be scraped too thick, and must be thoroughly sanded after drying, to achieve: the ground is flat.

When painting various coatings, the construction should be carried out in strict accordance with the requirements in the product description, and the dilution ratio should be strictly controlled.

Epoxy floor has the advantages of no joints, solid texture, good chemical resistance, anti-corrosion, dustproof, easy maintenance, and low maintenance costs. There are more and more applications in modern life, so the precautions for the construction of epoxy floor mainly include these points: the first generation of the bottom layer, the second concrete floor, surface treatment and repair defects, the third use of low solvent, low viscosity materials, the fourth painting, and finally the safety of the construction site.

1. Generate the bottom layer.

This is very important for epoxy flooring, when constructing the back cover, the construction personnel must first master the penetration and saturation of the flat ground, and carry out target backing. If the concrete is not strong enough, it should be reinforced.

2. Concrete floor, surface treatment and repair defects.

Epoxy floor construction includes concrete quality assessment, defect repair, and conventional surface treatment. Old floors should be satisfactorily coated with acids or alkalis or other chemicals. It is terrazzo or other hardened or particularly smooth to improve the adhesion of the coating.

3. Use low-solvent and low-viscosity materials.

Because the primer is solvent-free, low viscosity and strong permeability, while the medium and low molecular weight epoxy material has high adhesion. So the undercoat must be saturated. The dose should be evenly reached, the epoxy primer penetrates to a certain extent, the cracks are blocked by dust, and the deficiencies of the epoxy floor must be found during construction and treated.

4. Painting. Before painting the epoxy floor, the floor should be thoroughly cleaned, otherwise the overall coating effect will be affected.

5. Safety at the construction site.

During construction, on-site doors and windows need to be sealed. The workspace needs to be free of contaminants such as dust and impurities. The construction crew must be neatly dressed to ensure that no dust is generated during operation and that the surface effect, impact, of dirt generated by the external environment is minimized.

In addition, special attention should be paid to on-site fire prevention during construction. This is the most important step in the construction of epoxy floors.

If the above process is used for leveling, the quality of construction can be ensured. Epoxy flooring received the first "warranty".

The epoxy floor of the factory workshop is mainly for the appearance and improvement of the working environment of the factory workshop, so as to achieve green environmental protection, reduce the role of dust and ground moisture, the most commonly used epoxy floor paint on the floor of the factory workshop are: thin coating floor paint, epoxy self-leveling, epoxy anti-static floor, corundum wear-resistant floor, heavy anti-corrosion floor, etc.

Epoxy flooring is a kind of high-strength, wear-resistant, beautiful flooring, with no joints, solid texture, good chemical resistance, anti-corrosion, dust-proof, easy maintenance, low maintenance costs and other advantages.

However, the choice of epoxy floor paint on the factory floor floor is not something that can be done if you want to, you need to pay attention to the following points:

1. Whether the floor of the factory workshop meets the construction conditions of epoxy floor paint.

The factory workshop is not what you think can be constructed with epoxy floor paint, and the floor paint manufacturer is required to conduct ground surveys in the early stage to detect the moisture content, flatness, and strength and hardness of the existing ground. For the ground moisture content higher than 6% to carry out drainage treatment, flatness is not enough need to be polished, sand and ash is very serious is recommended to redo concrete, and then the construction of epoxy floor paint.

2. Whether epoxy floor paint can be used in the factory workshop.

Epoxy floor paint can be used on the factory floor! However, the workshop floor of different factory properties should choose to use suitable floor materials, and choosing the right one can avoid many external factors. Epoxy floor paint manufacturers suggest that for the factory workshop that requires a high degree of cleanliness, you can choose epoxy self-leveling floor, for the ground is just a dustproof person, you can choose an economical and practical epoxy flat floor, and the ground requires wear-resistant and compression-resistant and forklift walking, it is recommended to choose epoxy mortar floor, if you require anti-static, you can use epoxy anti-static floor.

3. Whether the on-site environment of the factory workshop meets the construction requirements.

The use of epoxy floor coating in the factory workshop takes time to solidify and form, so there are strict requirements for temperature and humidity, and the temperature is too high and too low, and the humidity is too large to properly delay the construction to avoid the quality of the floor caused by this problem. In addition, the construction site of the factory workshop needs to be closed to avoid dust and debris falling on the surface of the paint film and affecting the construction effect of epoxy floor paint.

4. The maintenance work after the epoxy floor paint is done in the factory workshop.

The epoxy floor paint in the factory workshop generally cannot be put into use immediately after the epoxy floor paint, and it needs to be cured for 7 days, and during the curing period, water or other solutions should be avoided from infiltrating the surface.

1. The construction site of epoxy floor should ensure good ventilation conditions, which can quickly and effectively discharge the harmful gases generated during the construction process to avoid poisoning by inhaling harmful gases for construction personnel;

2. Before construction, the ground on the site should be polished to maintain the flatness of the ground. At the same time, the ground dust should be cleaned regularly, so that the application effect of epoxy floor will be better;

3. The construction personnel should wear masks and goggles when carrying out construction, and wear special protective clothing for construction to avoid the paint splashing on the first or eyes during the construction process.

4. The coatings, adhesives and other flammable materials of epoxy flooring should be stored away from the fire source or high temperature area, and ensure the dryness of the environment, and do not smoke or use open flames at the construction site.

5. If there are special circumstances in some places and it is necessary to carry out operations in the process of construction, it is necessary to set up an isolation area with sufficient space to prevent dust, gravel, etc. from seeping into the ground under construction.

6. During the completion of construction, the construction personnel need to maintain the ground regularly, and clean up the ground in time if there is coarse hard gravel and dust, which can prolong the service life of the epoxy floor and reduce the wear and tear of the ground.

Safety precautions for epoxy floor construction:

1.In the process of epoxy floor construction, many equipment uses electricity. Electricity needs to be safe, so this is a big safety hazard.

2.Paints are organic and can be burned in the city, so attention should be paid to electric sparks and workers' cigarette butts during construction. Eliminate the potential danger of fire.

3.Solvents are all containing volatile gases, which are very prone to gas occurrence when they encounter sparks when they reach a certain concentration in the air.

4.Most of the materials and adhesives of floor coatings contain volatile and toxic gases, and workers will have poisoning symptoms and prevent poisoning when working in such an environment for a long time.

5.During construction, improper use of tools and machinery can cause harm to workers.

Safety precautions for epoxy floor construction:

Such as: fire prevention.

Flooring materials, adhesives, and other flammable materials should be stored away from fire and kept dry.

Fireworks are strictly prohibited on the construction site.

For example, to prevent the hazards of toxic gases and chemicals.

Flooring materials and adhesives for painting should be stored in an airtight manner.

On-site construction personnel should wear work clothes, masks, and goggles to avoid materials splashing into their eyes.

It is strictly forbidden to eat and live in warehouses and construction sites where toxic chemicals are stored.

For a large area of epoxy floor paint construction site, it should be worked in turns, so that the construction personnel can rest in the air circulation.

Such as: to prevent other existing safety hazards.

Measures to prevent falls from working at height.

It is strictly forbidden for construction personnel to work after drinking a large amount of alcohol.

Lighting of sufficient brightness should be ensured during night construction.

Floor construction equipment and tools are safe to use electricity, and pay attention to the inspection of lines.

In summer, attention should be paid to heat prevention, and special attention should be paid to not constructing in a high temperature and humid environment, which does not guarantee the quality of the project and damages the body.

In winter, the ambient temperature of the construction site should be ensured to prevent safety accidents caused by excessive wear and inflexible operation of workers, which will affect the quality of construction.

Whether it is a flooring enterprise or a flooring construction unit, a large team or a small team, each flooring project will do its best to pay attention to the details of every epoxy flooring construction safety precautions, and strive to do a good job in the project, so that they are satisfied, so that the owners are satisfied, and a win-win situation is formed.

Do you know some of the more special floors in the factory? Do you know the green floor in a hospital operating room? Do you know what are the characteristics of these grounds?

In fact, those painted floors are epoxy floors. For epoxy flooring, it has many excellent features, such as it is corrosion-resistant, anti-static, and wear-resistant and anti-slip, so epoxy flooring will be used in some industries, factories, hospitals, and warehouses. So do you know what are the characteristics of epoxy floor construction and what you need to pay attention to?

Here is an introduction to this type of construction.

Epoxy flooring is simply a process of painting on the ground, first of all, there must be a complete floor, and then a layer of epoxy floor paint is brushed on the epoxy floor, and the main process is like this. Epoxy floor paint is mainly used in an epoxy resin material, adding some dispersants, defoamers, curing agents and other raw materials to prepare a kind of paint.

Construction technology of epoxy flooring.

Before painting epoxy floor paint, you first need to polish the floor flat, you need to use a grinder to polish, and after sanding, you need to ensure that the ground is clean. For relatively large cracks or gaps, mortar needs to be used to fill them. A well-sturdy floor is not easy to crack after being painted, and a cracked epoxy floor will affect its service life, so you need to pay attention.

After the ground is leveled and cleaned, it is time to paint. There are four main layers for painting, the first is the base layer, which can be applied after mixing the curing agent and epoxy resin. This link only needs to be evenly painted, and then the next link can be carried out.

The next layer is called the middle coating, in this layer of epoxy resin not only with the curing agent but also with the quartz sand stirring, the same is simply coated with a layer, evenly applied, the purpose of this link is to make the ground firm. In this process, there will be a little unevenness after the ground dries up, and it needs to be sanded with a grinder, and the next layer will be carried out after the grinding is leveled.

This layer is called putty layer, only need to stir the quartz sand and epoxy resin, and then apply evenly, but in this link often need to be constructed several times, mainly requiring that there are no holes, if there are still need to continue to apply, until it is a flat ground.

The last layer of Zhenwang is the top coating, the paint and the curing agent are stirred evenly, carefully applied, generally need to be applied twice, to ensure that the ground is porous and seamless, to ensure the smoothness of the ground.

Different industries have different requirements for the performance of workshop floor coatings, which involves differences in construction methods. When water-based epoxy coatings are used for machinery, chemical industry, warehouse and other workshop floors, the floor needs to be impact-resistant, roll-resistant, wear-resistant, and corrosion-resistant.

etc., so it must be constructed according to the conventional process, that is, the base layer is treated with the primer epoxy mortar reinforcement layer putty topcoat. (1) Base treatment: For concrete floors with more oil stains, 10% 15% hydrochloric acid solution can be used to scrub and then use.

Rinse with water; For the general concrete floor with a large area, it can be treated by using an electric mill to grind and remove sand dust and oil stains. (2) Back cover: After mixing the epoxy primer A and B components evenly, roller coating on the surface of the base layer, preferably roller coating 2

to make it fully wet and penetrate into the interior of the concrete, which plays a role in bond strengthening. (3) Middle layer mortar: add an appropriate amount of mixed quartz sand with different particle sizes to the water-based epoxy coating and stir it evenly, and use the plastering method to make the coating reach a certain thickness.

Enhance the impact resistance and rolling resistance of the floor. (4) Putty: After the epoxy mortar layer is fully cured, scrape two water-based epoxy putty, polish and smooth after drying, and provide a smooth and solid base surface for the surface coating. (5) Epoxy floor paint coating: water.

The epoxy topcoat is evenly mixed according to the mass ratio of component A and component B = 1 1, brushed or sprayed on the base surface to make it self-leveling, and after curing, it becomes a flat, smooth and multi-functional floor coating with anti-static, corrosion resistance, antibacterial sterilization, and odor removal.

Layer. When water-based epoxy coatings are used in food, medicine, electrical appliances and other workshops or public venues, living room floors, they can be constructed according to the base layer of primer putty topcoat process. The construction method of each process is the same as above. The environment is required during construction.

Temperature" 12 and < 40 ; 15 40 is appropriate; The relative humidity in the air should be <85%, preferably 65%, otherwise, the coating will not cure well, which will affect the comprehensive performance of the coating.

Epoxy resin floor paint adopts a one-time coating process, no matter how large the area, there is no connecting joint, and it is also a dust-free material, with strong adhesion, friction resistance, strong hardness and other characteristics. At present, it has been used by many domestic manufacturers and.

Accepted and Used by the User. According to experts, the basic process of the two types of epoxy floor pavement is base treatment: grinding off loose layers, delamination and cement residues to make them hard and flat and increase adhesion; Primer application:

After the primer is matched, it is rolled, scraped or brushed to fully wet the concrete and penetrate into the inner layer of the concrete; Medium coating construction: the middle coating material is fully mixed with an appropriate amount of quartz sand, and coated into a flat and dense layer of a certain thickness with a trowel; Topcoat batch repair: the topcoat material is coated with quartz fine powder to fill the gap between the larger particles in the middle coat, polished with a dust-free grinder after complete curing, and the dust is sucked up with a vacuum cleaner; Topcoat construction:

After the epoxy pigment and curing agent are mixed evenly, trowel, brush, roller or spray are applied to level the leveling to obtain a smooth and uniform surface layer.
