Summer decoration guide causes of subsidence of wo

Brief content: when producing furniture in Europe, it is usually 24 hours before polishing after each primer is sprayed. After polishing, spray the second primer, wait for another 24 hours, and then polish. After polishing, spray the third primer, and then wait for another 24 hours. Now most wooden door factories choose Pu transparent primer. PU coating is indeed a kind of paint with good comprehensive performance, and the construction is also more convenient

extreme weather phenomena such as too high temperature, too dry, too much rain and too wet often occur in summer. Therefore, it has never been considered a good season for home decoration. In fact, as long as we pay attention to some important matters in summer construction, we can also avoid quality problems. Here, the editor of life home specially collected decoration information suitable for summer construction for you, hoping to help you pretend to be satisfied with your home this summer

two reasons for the subsidence of the coating surface of wooden doors

when we communicate with the bosses, salespersons and production managers of wooden door enterprises, we often hear the reflection: the surface effect of the newly produced wooden door is very good, but after placing it for a period of time, we find that the surface effect of the product is not good, the gloss is weakened, and the surface layer is not so flat. What is the problem? In fact, the reason for all this is: the surface of the coating sinks

why does the coating on the surface of coated products sink? There are two reasons: first, it takes a long time for the paint to dry completely after spraying. Generally, furniture factories and wooden door factories only wait for threeorfour hours before polishing. In fact, at this time, the paint is not completely dry, the residual solvent will continue to volatilize, and the paint film itself will continue to shrink. If the product is ready at this time, it will naturally affect the future surface effect of the product; Second, all substances in nature will sag under the gravity of the earth's center of gravity, so the paint layer after film formation will gradually subside as long as there are wooden holes in the underlying materials (solid wood, wood skin) that have not been filled. The subsidence of the paint layer with high hardness will be slower, and the subsidence of the paint layer with soft will be faster

how to prevent the coating from sinking

when furniture factories and wooden door factories are producing high-quality products, they should pay attention to the above problems. Try to fill the wooden holes completely, and give the paint film enough time to dry and sink before grinding

when producing furniture in Europe, it is usually 24 hours before polishing after each primer is sprayed. After polishing, spray the second primer, wait for 24 hours, and then polish. After polishing, spray the third primer, and then wait for 24 hours. Only when the flat primer is fully prepared can the top coat be sprayed. The main reason for this operation is to polish and flatten the coating after it has fully subsided. In this way, the final product is not easy to sink, so that the final product has a more perfect effect and stability

to build a house, we must first lay a good foundation; The same is true of paint. If the primer is not handled well, no matter how hard you try later, it is impossible to make a good product. There is a famous saying in China: slow work makes fine work. If we are eager for success in painting and violate the laws of nature, it is very difficult to make excellent products

but at the same time, we should also face the reality correctly: it is unrealistic for our factory to produce furniture and wooden doors like European enterprises. Because the manufacturing cost of our products does not allow such time-consuming operations

is there a way to make a better and more stable surface coating effect as far as possible while ensuring the existing production efficiency? The answer is yes. We can make some improvements in the selection of coating varieties and the design of process

now most wooden door factories choose Pu transparent primer. PU coating is indeed a kind of paint with good comprehensive performance, and the construction is also relatively convenient. However, if we want to produce wood door products with higher requirements, we suggest that PE transparent primer can be used as the primer. Under the same process, the surface coating effect and stability of the product made by it are much better than that of Pu transparent primer commonly used now. This is determined by some irreplaceable excellent properties of PE paint
