Nowadays people are really paying more and more attention to the decoration of houses, and these are also hardcover. I don't know that everyone knows about epoxy flooring. In fact, there are many characteristics of epoxy flooring, such as high strength, wear resistance, beautiful flooring, with seamless, solid texture, anti-corrosion, dust and other advantages. So what are the requirements for the environment when choosing epoxy floor construction?
Hardness refers to the strength of the coated base or the label of the concrete base. The hardness of the coating base fundamentally determines the service life of the coating, the adhesion of the coating and the application effect of the coating.
Flatness refers to the key index of coating base surface flatness or not. The smoothness of the base surface fundamentally determines the smoothness of the coating. The smoothness of the coating directly affects the application effect of the coating.
Thickness refers to the thickness of the concrete layer on the most surface of the coated base (structural layer), not the thickness of the whole base. If the thickness is too thin, it is easy to delaminate and empty. The minimum thickness of the structural layer of the surface layer is required to be more than 5 CM hardness C25.
Humidity refers to the moisture content of the base surface and the air humidity of the coating environment. Different floor coatings have different requirements for the moisture content of the base surface. Epoxy floor coatings require less than 8% and methyl methacrylate resin requires about 10%. If the moisture content of the base surface exceeds the standard, blisters, bulging and falling off of the whole coating may occur. The moisture content in the air is humidity, which can be measured by hygrometer. Generally, the best humidity for epoxy floor paint construction is below 85%, but not below 30%.
Temperature refers to the temperature of the coating environment, which can be measured by a thermometer. Different kinds of floor coatings have different requirements for temperature. The epoxy requirement is above 5 Celsius, of course, the temperature is too high to be constructed. One is dangerous, the other is that too fast curing is not conducive to the performance of the coating.
Cleanliness refers to the absence of other coatings or sundries, including dust, oil, cement residues, other paints, etc., except for floor coatings.
通风度，是涂装环境通风与否的指标等 。 因双组份或多组分的地坪涂料固化时会产生热量和水气必须及时由流动空气带走，所以要求涂装环境相对通风，但也不能太过通风。
Ventilation is an indicator of ventilation in painting environment. Because the heat and moisture generated when two or more components of floor coating solidify must be taken away by the flowing air in time, the painting environment is required to be relatively ventilated, but not too ventilated.
Roughness refers to the small spacing of the surface of the base surface and the unevenness of the small peaks and valleys. The local distance (wave distance) between the two peaks or troughs on the ground surface is very small, which requires less than 1 mm. It belongs to geometric error. The smaller the roughness of the base surface is, the smoother the surface is, the smaller the contact area ratio between the coating and the base surface is, and the adhesion of the coating will also decrease, otherwise the adhesion of the coating will increase.
