How To Control Blasting And Painting Environment

Prefabricated warehouse supplier have great influence on the quality of paint film, in order to ensure the coating quality, the coating environment request as follows:

1.Open-air homework under the climate sunlight and rain, fog, snow condition is not allowed; It is not fit for construction when the relative humidity is more than 85%; Substrate temperature should be higher than 3 ℃ above the dew point before construction. ET - 98 type inorganic phosphate long-acting zinc-rich coatings might as well.
2.In summer day, when substrate temperature greater than 60 degrees can't construction. In winter the temperature of no less than 5 degrees below zero, 70 - H iron red epoxy anticorrosive paint, H06-3 epoxy micaceous iron oxide antirust paint, ZHL51-2 super high build epoxy tar antirust paint should not be in outdoor construction.
3.Shouldn’t construct, when it with dust float in the sky in the coating and paint film drying process. ET - 98 type inorganic phosphate long-acting zinc-rich coatings might as well, because of its three minutes to reach the surface dry.
4.For the galvanized layer, it is necessary to choose light level sand blasting method to remove the ash layer, oil and other impurities, then besmear brushs 70 - H iron red epoxy anticorrosive paint.
