Cailv the water surface treatment using electrostatic powder spraying process. First, what is powder coating? The world's first set of powder coating equipment developed in 1962 by the French SAMES company successfully, then powder coating technology in the world is developing rapidly. The working principle relies on electrostatic powder coating sprayed onto the surface, the powder particles to each other without adhesion layer melted by heating to form a strong coating and surface closely. This coating has excellent corrosion resistance and decorative features. Workpiece into the powder room by conveyor gun position ready to spray job. The release of high-voltage electrostatic generator electrostatic (negative) direction of the workpiece into the space through the muzzle of the gun electrode needle, the high voltage from static electricity. Mouth spray gun powder and a mixture of compressed air and the surrounding air ionization electrode (negatively charged). After hanging a piece by transport links ground (earth electrode), so between the gun and the workpiece to form an electric field accounts for the powder to reach the surface in the double electric force and air pressure driven, relying on electrostatic attraction is formed in the surface layer uniform coating. Second, the advantages of electrostatic powder coating equipment and materials: Switzerland ", Kinmen and Matsu" Automatic spray line Netherlands 'Akzo' powder coating, non-toxic, odorless, non-polluting. 2, strong adhesion, good impact resistance. Transportation and installation process without any protective film, do not worry about scratching the surface and fall off. 3, corrosion resistance, high insulation, anti-aging. 4, beautiful rich color can be matt simple, it can be elegant, to meet customer's individual choice. Third, the shortcomings of a powder coating process requires careful complicated. 2, the baking temperature is high (C ° 200 or more), increase in cost. 3, production fast enough. Aluminum oxide film formed on the surface layer of invisible, no aluminum oxide, the self-protection of the aluminum with high corrosion resistance; secondly aluminum substrate surface covered with colored polyester coating, color stability ; coefficient of thermal expansion coefficients of the base layer and the third aluminum cement close Cailv the water system is not in use, resulting in risen and crack, resulting in leakage; while aluminum at temperatures between -45 ° to 260 ° C, strength, the same performance; it can in the cold regions such as northeast China, as the strong sun in southern China, such as resistance to large temperature under changing China's Xinjiang and other inclement weather use; to ensure lasting as new. Cailv the water system of product standards: product quality Cailv the water system requirements refer to "building walls with APCP" GB / T17748-2008, size deviation, thickness deviation, adhesion, impact resistance, acid and alkali resistance, oil resistance, salt spray and other indicators are to meet the requirements. Note: The use of aluminum siding should be used in 5005,3003 aluminum sheet: according to national standards GB / T7748-2008 provisions of the aluminum siding should be consistent with GB / T3380 requirements of rust-proof aluminum, ready to use. Material: 3003 aluminum-manganese; (rust-proof aluminum and manganese can be added to a small amount of grain refinement to improve resistance to stress corrosion performance) coating products: outdoor polyester paint roller coating, roll coating production process.
