From the perspective of the future development of coatings, weather aluminum alloy building profiles are important performance indicators, but due to differences in their use environment, geography, etc., different standards can be adopted. "In the doors and windows of aluminum door and window materials, the material is connected with the wall." Its main feature is that the surface at the junction with the wall is mostly flat, fixed on the wall and cannot be moved. "Household aluminum is a coating technology. It is based on the traditional titanium electroplating process, adding pre-plating and electroplating processes. The pre-plating process is to chemically treat the activated electroplated parts in an aqueous solution of salt and hydrochloric acid .Due to the combination of curtain wall technology and science and technology, door and window curtain walls, in response to the global call for energy conservation and emission reduction, smart curtain walls, such as solar photovoltaic curtain walls, ventilation channel breathing curtain walls, wind and rain sensing smart curtain walls, etc., will show the unique charm of the building. Therefore, you Paint can be selected in a targeted manner.

     Polymers based on acrylic materials and their main esters have high weather resistance, which is mainly determined by enterprise monomers. It is formed through the research of the polymerization method and has strong stability to the light environment. Without proper selection of monomers, the film will have excellent light preservation. This resin has better weather resistance than polycondensation-formed polymer networks. As a coating company like China, it must also have excellent corrosion resistance. The key is to form cross-linking of the coating film. Hexamethoxymethylmelamine is used as a cross-linking agent, which has good performance in curing process management. Excellent cross-linking performance, so that the coating film has high hardness, gloss, color (no yellowing) and excellent weather resistance. "In recent years, the appearance of cathodic electrophoretic coating with better light resistance is also a good choice for us, and its corrosion resistance is also better. It is a kind of isophorone isocyanate (IPDI) or The polyamine resin system structure composed of aliphatic isocyanate (aliphatic isocyanate) has excellent weather resistance and can be directly made into CED. There is no need to consider the oxidation of CED to industrial aluminum profiles, because in the process of electrodeposition technology, electrophoresis The behavior of the analysis is directional and cathodic, and the oxide film will be destroyed by different students or all information. However, this traditional coating still has many excellent corrosion resistance and weather resistance, and many people even think that it is the first in the field of construction engineering in our country development and changing trends.

     In terms of coating method, electrodeposition method is an ideal automatic production method, which has high production efficiency and coating efficiency as high as 95% (the anodic electrophoretic coating produced by aluminum is generally 82%, mainly due to viscosity efficiency and The anti-interference of the performance reduces the coating liquid), and the stable film quality is produced by ED, which is the electrostatic method of coating, and the current density of the first part of the coating is high, after the formation of film resistance increases, there is no formation And the large current density flowing part of the adjacent part is formed, so that the coating is continued, so that all parts of the workpiece are formed by high resistance, and then the coating does not prolong the ED and no longer thickens the time, and the geometry of the contour groove is obtained uniformly on the site The thin film thickness coating, called ED throwing rate compound, has improved in the case of such excellent corrosion resistance, weather resources, and Meng Qingxiang.
