Powder spraying can effectively prolong the service life of industrial aluminium sheets
From the point of view of technology itself, it has quite high scientific and technological components, dispensing paints with different colors, producing decorative effects of different color systems, which is more in line with the needs of interior decoration, and is also consistent with the trend of industrial aluminium sheet application in the construction industry to interior development. Especially the joint use of sprayed profiles and thermal insulation bridges makes it more fashionable, and makes powder sprayed profiles have greater development space, which is also irreplaceable by profiles produced by other processing methods.
At present, the powder coatings commonly used in three-sided advertisements are weather-resistant polyester powder coatings. Most of the polyester resins used in powder coatings are saturated. Usually, according to the structure of their end groups, they can be divided into two categories: carboxyl-terminated and hydroxyl-terminated. When powder spraying combined with thermal transfer technology is used for aluminium sheet, it will become more fashionable and have more development space for powder spraying profiles.
Powder coating spraying process is relatively simple, high yield, in general, if appropriate measures, can maximize the control of the production of substandard products; energy consumption is significantly reduced, in the ordinary process of anodic oxidation, electrophoretic coating production, water and electricity consumption is quite large, industrial aluminum plate processing, especially in the oxidation process. Its pollution degree to water and air is reduced, the use of tablet alkali, sulfuric acid and other liquid organic solvents is no longer used, and the pollution of water and air is reduced. It also effectively improves the competitiveness of aluminium sheet and plastic steel profiles as environmental protection products, and accordingly reduces some production costs. The labor intensity of workers is significantly reduced, due to the use of automated assembly line operation, the way of industrial aluminium sheet material and the use of industrial aluminium sheet material. The use of fixture has been obviously simplified, the production efficiency has been improved, and the labor intensity has also been reduced; the surface quality standard of wool material has been significantly reduced, and the surface quality of finished aluminium sheet products has been improved; and some physical indexes of aluminium sheet coating have been significantly improved compared with other surface treatment films, such as hardness, three-sided advertisement, wear resistance and acid resistance, which can effectively prolong industrial aluminium sheet. Service life.
