Water-based wood lacquer construction in high temperature and high humidity weather, don't ignore these problems
Waterborne wood lacquer construction under high temperature or high humidity often causes some abnormal problems: such as wrinkling of paint film, poor adhesion of paint film, cracking of paint film, whitening of paint layer, etc., which will affect the construction progress and decorative effect. Then, what issues should be paid attention to when constructing waterborne wood lacquer under high temperature and high humidity? 1. Film wrinkle The waterborne wood lacquer film will dry quickly at high temperatures, while the thick inner layer will dry slowly. During the drying process, the flow of the lacquer will produce a poor tension, resulting in an uneven film surface, which is what we often call wrinkling. Therefore, do not form at the time of construction, should be thin coating to ensure that the coating is evenly dried to form a film, to achieve a smooth film effect. 2. Poor adhesion of paint film In the high temperature and high humidity environment, after the construction of the general waterborne wood lacquer, it will be found that the coating is not firmly bonded, resulting in poor adhesion, and the layers are peeled off from each other, and even the whole piece can be peeled off like a peeling peel. , resulting in poor adhesion between the layers of the paint film. The direct cause is that the painter did not polish the layers during construction. Therefore, in the construction of high temperature weather, each floor should be fully polished to improve adhesion, and construction should be arranged in the morning and evening to ensure the quality of the products. 3. Paint film cracking This phenomenon is also common in high-temperature construction. Because the coating film is too thick during the construction process, the surface layer is dried and the film formation speed is fast, while the thick inner layer is dry slowly, which directly causes the paint film to crack. phenomenon. At the same time, we must also pay attention to the quality of the sheet, it is recommended to buy a stable sheet. 4. The paint layer is white Mainly due to the construction environment humidity is too large, the paint film is too thick during construction and other reasons. Because of the high temperature, the air humidity in some areas is relatively high, the dry time of the paint layer is accelerated with the increase of the temperature, but the dry time is slower. The painter often ignores the dry time during the construction process, while the paint layer is in the paint layer. Immediately after the drying, the next construction was carried out, resulting in the bottom paint layer not being completely dried. In the case of heavy rain or high humidity, it is most likely to cause whitening of the paint layer.

Color
coated Steel Coil
Color Coated Steel Coil is a product
which is coated with one or several layers of organic coatings on the surface
after baking, and then after surface pre-treatment (chemical degreasing and
chemical conversion). Also because of the various colors of different colors of
the organic paint color steel roll plate from this, referred to as color
coating.
Advantages: Color coated steel coil is with light weight, beautiful appearance and
good corrosion resistance. Color coated steel coil can also be directly
processed. Color is generally divided into gray, blue and brick red. Color
coated steel coil is mainly used in advertising, construction, household
appliances, electrical appliances, furniture industry and transportation
industry.
