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 company SAMES success, then powder coating technology in the rapidly developing countries in the world. Its working principle relies on electrostatic powder coating is sprayed onto the workpiece surface, the powder particle layer without sticking to each other through heating and melting after the formation of a durable coating and the workpiece surface closely. This coating has excellent corrosion resistance and decorative features. Workpiece into the powder room by conveyor gun position ready to spray job. Electrostatic high-voltage electrostatic generator release (negative) direction to the space of the workpiece electrode needle through the gun muzzle, from the high-voltage static electricity. Gun powder discharge port and a mixture of compressed air and the surrounding air ionization electrodes (negatively charged). After hanging workpiece transport links by land (grounding), so between the gun and the workpiece to form an electric field to reach the surface accounts for powder in the double push electric force and air pressure, relying on electrostatic attraction to form a layer on the surface uniform coating. Second, the advantages of 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, can be rich, beautiful color, can Matt simple, can be elegant, to meet customer's individual choice. Third, the shortcomings of a powder coating process requires careful complicated. 2, a high baking temperature (C ° 200 or more), increase in cost. 3, production fast enough. Aluminum oxide film formed on the surface layer of invisible, no aluminum oxide, this self-protective aluminum with high corrosion resistance; secondly aluminum substrate surface covered with colored polyester coating, color stability ; coefficient of thermal expansion coefficients of the third and cement grassroots aluminum close Cailv water system does not use, causing cracks and risen, resulting in leakage; while aluminum at temperatures between -45 ° to 260 ° C, strength, the same performance; it can in cold regions such as the Northeast China, southern China, such as the sun and strong resistance, such as under large temperature changing China's Xinjiang and other inclement weather use; ensure lasting as new. Cailv the water system of product standards: quality products Cailv 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 wall panels should be used 5005,3003 aluminum sheet: according to national standards GB / T7748-2008 regulations, the aluminum wall panels shall comply with GB / T3380 requirements of rust-proof aluminum, ready to use. Material: 3003 aluminum and manganese; (rust-proof aluminum and manganese can add a small amount of grain refinement to improve resistance to stress corrosion performance) coating products: outdoor polyester paint roller coating, roll coating production process. Internal gutters and downspouts are required anticorrosion coating roll coating advantages: ① three bake three-coat: primer, topcoat, back coating. (Spray just over coating, no preservative back coating) ② T≤2. ③ uniform color, no color. ④ can provide 300 hours aging test report (equivalent to approximately 5-6 years). ⑤ chemical resistant: 5% HCL, 24h and 3% NaOH, 24Hh; surface change. ⑥ Impact resistance: Bending 2T, surface without peeling, no cracks phenomenon. ⑦ product with PE protective film to prevent the transport, installation scratch. Experiments φ90 (3 inches) Cailv the water system: Model: Color: gray or dark brown Thickness:. A gutter: 0.7mm b downspouts:. 0.9mm square tube: 82 × 63 (3 × 2 inches) pipe Data: bending test: a hand press slowly 180 ° bending test (at room temperature), Cailv the water system no peeling no cracks. Impact experiment: a diameter of 15mm quality 500 gram ball 5m from where the fall, Cailv the water system is not peeling. Salt eclipse experiment: carry out cross-cut with a cutter to just touch the aluminum sheet date, at 35 degrees / C conditions, 5% salt solution spray 360 hours. Cailv water system track the spread of rust from the incision does not exceed 2mm. Temperature experiments: in the arctic cold of minus 50 degrees and 60 degrees equatorial insolation conditions of high temperature use, stable performance Cailv the water system, such as a color. Acid erosion experiment: 10% of HCL, CHCOOH, H2SO4 experiment 100 hours. Cailv surface water system unchanged.
