PVDF Aluminium Extrusion Profiles

 PVDF aluminium extrusion profiles process is:

　　Pre-treatment process: degreasing and decontamination of aluminum material → washing → alkaline washing (degreasing) → washing → pickling → washing → chromizing → washing → pure water washing

　　Spraying process: spray primer → top coat → finish varnish → baking (180-250℃) → quality inspection

The generation of electrostatic spraying solves the surface treatment of the curtain wall aluminum plate, which not only reduces the color difference, but also obtains aluminum plates of various colors.

Electrostatic spraying is divided into powder spraying and fluorocarbon spraying. The raw materials of powder spraying are: polyurethane, polyurethane resin, epoxy resin, hydroxy polyester resin and epoxy/polyester resin, which can be formulated in a variety of colors. The characteristics of powder spraying: spraying equipment is manual, with automatic hanging type, simple construction, coating thickness of 30 microns or more, impact resistance, abrasion resistance, corrosion resistance, weather resistance, etc., the coating price is higher than fluorocarbon Cheap. The major weakness of powder spraying is that it is afraid of ultraviolet rays from the sun. Long-term exposure will cause natural fading. The color difference between the sunny side and the non-sunlight side of the aluminum plate will be obvious after a few years, generally 2-5 years. Nowadays, colored PVDF aluminium profiles appear on the market. They are used for aluminum doors and windows and are sprayed with ordinary PVDF aluminIum profile powder. Increase the color variety of aluminum doors and windows, and also enhance the corrosion resistance.

The performance of PVDF aluminium profiles is determined by its performance. The spraying equipment must ensure an excellent atomization effect and the uniformity of the sprayed layer. The distribution of metal particles in the fluorocarbon paint directly affects the appearance of the coating. The coating is uniform, and the quality fluorocarbon coating has a metallic luster, bright color and obvious three-dimensional effect. The fluorocarbon spray coating with improper spray equipment will cause uneven color, shadow on the surface or weak coating. It greatly affects the decorative effect of fluorocarbon. In order to achieve a good spraying effect, high-voltage electrostatic electric spray guns are used. The United States, Japan, Germany and other countries produce various types of spray guns in various forms. Each has its own characteristics.

The fluorocarbon spraying process mostly uses multi-layer spraying to give full play to the durability and weather resistance of Kynar500 metallic paint. From the front surface treatment of PVDF Aluminum Profile to the spraying process, strict quality control is required, and the final product must be made in the United States.
