What are wood grain transfer , powder coating and PVDF for doors and windows?
Aluminum alloy doors and windows are more and more popular with consumers due to their stylish and beautiful appearance, energy saving, environmental protection and safety. Whether the surfaces of doors and windows are smooth, whether the color is beautiful, and whether the degree of clarity and life are clear and realistic will affect the customer’s desire to buy. So what kind of technology can create high-end surface treatment? Now UTENCH will introduce three common surface treatment methods for doors and windows.
Wood Grain Transfer
Door and window profiles with wood grain surface are usually surface treated by wood grain thermal transfer. The substrate condition of the wood grain heat transfer workpiece: powder spraying or electrophoretic coating must be performed before transferring. The process is as follows: substrate spraying or Electrophoresis-film-190-200 ° C baking-film removal-packaging, through a certain temperature on the aluminum coating organic coating matrix, the ink sublimation on the transfer paper is transferred to the substrate coating, so as to obtain a clear and complete picture .
Powder Coating
Powder spraying uses the principle of electrostatic spraying to adsorb the dry powder on the metal aluminum profile. After being roasted at a temperature of 200 ° C or higher, the powder is solidified into a layer of about 60 microns thick, strong and bright. Make the product surface smooth and even in color. It has strong acid resistance, alkali resistance, impact resistance and abrasion resistance. It can withstand the erosion of strong ultraviolet radiation and acid rain for a long time. Powder coated aluminum profiles have a service life of 30 years under normal conditions. Its surface coating does not fade, discolor, and crack within 5-10 years. Its weather resistance and corrosion resistance are better than ordinary aluminum.
Polyvinylidene Fluoride
Polyvinylidene Fluoride is not only an electrostatic spraying, but also a liquid spraying, which is called curium oil in Hong Kong. It belongs to high-grade spraying with high price.
Polyvinylidene Fluoride has excellent anti fading, anti frosting, anti atmospheric pollution (acid rain, etc.), strong UV resistance, crack resistance and can withstand severe weather environment. It’s better than ordinary paint. Polyvinylidene Fluoride coating is a kind of coating which is based on polyvinylidene fluoride resin nch2cf2 n (PVDF) or mixed with aluminum powder. In the chemical structure of fluorocarbon based materials, fluorine / carbon bond is used. This kind of structure with short bond property combines with hydrogen ion to become the most stable and firm combination. The stability and firmness of chemical structure make the physical properties of fluorocarbon coating different from general coating. In addition to the mechanical properties of wear resistance, impact resistance has excellent performance, especially in bad weather and environment shows a long-term anti fading, anti UV performance.
