The difference between fluorocarbon aluminum veneer and powder aluminum veneer

　　导读：铝单板是现在幕墙最重要的材料，而铝单板也分为很多种，根据性能有不同的材质，很多做幕墙的朋友都会问Fluorocarbon aluminum veneerAnd powder aluminum veneer what is different, why the difference is so big, the following by Kaimai metal building materials to introduce you to three differences:

　　Different spray materials applied by 1.

Fluorine aluminum veneer, the use of PVDF fluorocarbon coating, it has good weather resistance, water resistance, pollution resistance, cold resistance, high temperature resistance, chemical resistance, especially for the exterior decoration of buildings with other coatings can not be compared to the advantages.

Powder aluminum veneer is to use powder spraying equipment (electrostatic spray molding machine) to spray the powder coating to the surface of the aluminum veneer, under the action of static electricity, the powder will be evenly adsorbed on the surface of the aluminum veneer, the formation of powder coating powder coating after high temperature baking leveling after curing the final coating color.

　　Different processes for 2. fluorocarbon spraying and powder spraying

Fluorocarbon spraying: PVDF fluorocarbon coating is insoluble in common solvents. The formation of coating film requires high temperature sintering at 230-250 ℃, so fixed spraying equipment and high temperature baking equipment are required to process and spray fluorocarbon aluminum veneer and fluorocarbon aluminum profile on the surface of fixed processing places.

Powder spraying: the powder is first packed in a powder device, and the powder is in a fluidized state under the action of air pressure. the powder is carried by high-speed air flow through siphon action to form a powder-gas mixture, which passes through a powder pump and a powder conveying pipe, is electrostatically sprayed on the surface of an aluminum veneer, and is then heated, baked, melted and solidified. (Baking temperature: indoor plastic powder 180 ℃,20min; Outdoor plastic powder: 200 ℃,20min) to form a smooth and bright permanent coating film and form the final powder coating process.

Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, non-volatile, non-polluting, saving energy and resources, reducing labor intensity and high mechanical strength of the film.

Surface film thickness is different:

Fluorocarbon spraying: the surface film thickness is about 35-60μm;

Powder spraying: the surface is 50-80μm thick, and the film thickness is different due to different processes.?

　　3. surface effect is different

Fluorocarbon spray generally can only do matte or gloss is not bright color.

Powder spraying can do matte, also can do high gloss color, and can do orange peel, grinding yarn grain characteristic grain color.
