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
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
2 ° hardness
Hardness refers to the strength of the coating surface or the concrete
The hardness of the coating surface fundamentally determines the useful
life of the coating, the adhesion of the coating, and the effect of the
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
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.
