As a science, wooden door painting, like all other scientific fields, has endless exploration.
It is always in constant progress and development.
As a substrate, such as medium density fibreboard, plywood, Blockboard, etc., wood-based panels are required to be smooth and smooth, with uniform thickness and no defects such as warping, edge defects, delamination, bubbling and so on.
When transparent finishing, the color of the substrate should be the same, and the color defects of the plate should be controlled.
Solid wood as a base material, such as solid wood square wood, solid wood finger joint wood, and so on, its surface treatment is a special treatment on the basis of normal machining.
Generally include greasy flat, sanding, surface cleaning, wood hair removal and other processes.
According to the surface conditions of specific tree species and machined wood, it is sometimes necessary to remove resin, bleach and partially or completely modify the color of the substrate.
The surface of the substrate should be carefully sanded to make it smooth and smooth without any defects.
When using veneer veneer for finishing production, because the veneer is very thin (usually 0.2~0.3mm), the defects of the substrate can easily be reflected on the finishing surface through the veneer, so the substrate must be strictly selected.
The substrate with knots, cracks and resin sacs must be repaired, and all kinds of substrates should be strictly sanded before veneer pasting.
In modern wood finishing, the understanding of the surface quality of the substrate has changed from "three-part carpentry and seven-part oil worker" to "three-part paint and seven-part wood". It can be seen that the modern painting industry has fully realized the important influence of the surface quality of the substrate on the final painting effect, and changed the traditional wrong idea of relying on finishing paint (paint) to cover up and make up for the bad substrate.
