In the floor coating of wooden floors, the following reasons are mainly caused by the uneven thickness of the coating film during the coating process of the light-cured floor paint.
The gap between the two edges of the curtain coating machine is inconsistent, resulting in a difference in the amount of epoxy floor paint coating, resulting in uneven coating thickness. Shower knife blade wear or impurities blocking, so that the amount of paint spilled out of different sizes, resulting in uneven paint coating. The uneven heating of the topcoat before coating causes the viscosity of the coating to be inconsistent, the viscosity to be low, the flow velocity to be fast, the viscosity to be high, and the flow velocity to be slow, resulting in the difference in the thickness of the epoxy floor coating film.
There are usually the following three methods for the floor coating company to deal with the uneven thickness of the coating film.
Before spraying the floor paint, adjust the curtain of the shower curtain to the right and left. When the knife edge is worn, it is necessary to remove the knife edge to repair or replace the new knife edge. At the same time, clean the debris and strengthen the filtering of the paint. The coating machine paint barrel is heated, and at the same time, the floor paint circulation pump of the spray coating machine is turned on, so that the temperature of the coating is uniform and the filtering of the coating is strengthened.
In the construction of the floor paint on the wooden floor, the phenomenon of bubbles appearing in the coating of the photocurable coating of the shower coating is as follows.
Photocurable coatings have poor defoaming properties. The coated wood is not putty layer, so that the first primer can not fully fill the capillary pores of the wood. The air in the pores expands and evaporates after being heated by the hot topcoat, the leveling machine and the curing machine, and is coated on the epoxy floor paint. Small bubbles are formed in the film and entrapped in the cured film to form bubbles; larger bubbles break through the film and form pinholes. Such problems can be solved after floor painting companies deal with them in the usual way.
