Epoxy floor paint construction environment requirements of high octave
Epoxy Floor paint is a high value, high quality, high demand for products, why the epoxy floor paint on the environmental requirements of high "octave", which "octave" it?
1 ° flatness
Flatness refers to the coating of the base surface formation or not the key indicators.
The flatness of the base surface fundamentally determines the flatness of the coating, and the flatness of the coating directly affects the effect of the coating.
2 ° hardness
Hardness refers to the strength of the coating surface or the concrete base.
The hardness of the coating surface fundamentally determines the useful life of the coating, the adhesion of the coating, and the effect of the coating.
3 ° thickness
Thickness refers to the thickness of the coating on the base layer (the structural layer), not the thickness of the entire base.
Thickness is too thin, it is easy to delamination, hollowing. The minimum thickness of the structural layer of the surface layer is required to have a hardness of 5 cm or more.
4 ° temperature
Temperature refers to the temperature of the coating environment, can be measured with a thermometer.
Different types of floor coatings on the temperature requirements are inconsistent. Epoxy requirements above 5 ℃, MMA requirements -25 ℃ or more. Of course, the temperature is too high can not be construction, one dangerous, two curing too fast is not conducive to coating performance.
5 ° humidity
Humidity refers to the moisture content of the coating surface and the air humidity of the coating environment.
Different floor coatings on the coating surface moisture content requirements are inconsistent, epoxy floor coatings require 8% or less, methyl methacrylate resin requirements of about 10%. Base surface of the water content exceeded, floor paint then the coating may be blisters, from the drum, the whole film off and so on. The moisture content in the air is the humidity, which can be measured with a hygrometer. Generally, the optimum humidity is 85% or less, but not less than 30%.
6 ° roughness
Roughness refers to the smaller spacing of the surface of the coating surface and the unevenness of the tiny peaks and valleys.
It belongs to the geometric error. floor paint The smaller the roughness of the base surface, the smoother the surface, the smaller the contact area between the coating and the base surface, the lower the adhesion of the coating, whereas the adhesion of the coating will increase.
7 ° ventilation
Ventilation degree, is the coating environment ventilation or not indicators.
Due to two-component or multi-component floor coating curing heat and moisture must be generated by the flow of air in time, so the requirements of the painting environment is relatively ventilated, but not too ventilated, floor paint so as not to cause pollution.
8 ° cleanliness
Cleanliness refers to the addition of paint in addition to other coatings or debris, including dust, oil, cement residue, other paint and so on.
