Why does the coated coating on the surface of the product sink? There are two reasons for this: First, after the paint is sprayed, it takes a long time to dry completely. Generally, the furniture factory and the wooden door factory only wait for three or four hours to polish. In fact, the paint is not completely dried, and the residual solvent. Will continue to volatilize, the film itself will continue to shrink, if the product is already done, it will affect the surface effect of the product; second, all the substances in nature will be drooped by the gravity of the Earth's center of gravity, so after film formation The paint layer, as long as the following materials (solid wood, veneer) have not been filled with wooden eyes, will gradually sink, the high-hardness paint layer will sink slowly, and the softer paint layer will sink faster.
How to prevent the coating from sinking?
When furniture factories and wooden door factories produce high-quality products, they should pay attention to the above problems. Try to fill the wooden eye completely, and give the paint film enough dry and sag time before grinding.
When producing furniture in Europe, it is usually necessary to wait for 24 hours for the primer to be applied. After the polishing, spray the second primer, wait for 24 hours, then polish, and then spray the third. Next primer, wait another 24 hours to polish. The top coat is sprayed only when the flat primer is fully prepared. The main reason for this operation is to smooth the coating after it has been fully sunk. In this way, the final product is not easy to sag, so that the final product has a perfect effect and stability.
To make a house, you must first lay the foundation; the same is true for paint. If the primer is not handled well, it is impossible to make a good product after hard work. We have a famous saying in China: slow work and fine work. If we are eager to make a job in painting, it is very difficult to make a fine product in violation of the laws of nature.
But at the same time, we must also face the reality correctly: if our factory produces products like European companies to produce furniture, wooden doors is not realistic. Because the manufacturing cost of our products does not allow such time-consuming operations.
So, is there a way to make a better and more stable surface coating effect as much as possible while ensuring the existing production efficiency? The answer is yes. We can make some improvements in the selection of coatings and the design of the process.
Most of the wood door factories now use PU transparent primer. PU coating is indeed a kind of paint with good comprehensive performance, and the construction is also convenient. However, if you want to produce more demanding wooden door products, we suggest that PE transparent primer can be used as the bottom. Under the same process, the surface coating effect and stability of the product are much better than those used now. PU transparent primer. This is based on some of the irreplaceable performance of PE paints.
