vpci-609 anti-rust powder US imports Yantai treasure agent 5 August 2014 11 ..

VpCI-609 is a water-soluble VCI powder. Metal enclosed space suitable for dry or wet rust. VpCI-609 gasification or dissolved, adsorbed on all metal surfaces, including hard to reach the surface pores, cracks, etc., to form a protective layer, can be very effective in preventing corrosion of metal surfaces. Features * Suitable for carbon steel, rust-proof stainless steel, aluminum and other metals. * For a covered, enclosed metal rust space. ? When wet-rust, which can prevent the liquid, liquid interface and surface corrosion than metals. * Does not contain phosphates, nitrites and heavy metals. It does not require surface preparation. ? No increase in alkaline. Closed space is opened and then closed, still has a protective function. Typical physical and chemical properties · Appearance white crystalline powder · PH 6.5 ~ 6.9 (1% aqueous solution) · 15% solubility in water of 24 months antirust · Recommended use · compressors, turbines, cylinder-type structure, pipes, tanks, boilers and heat rustproof inner surface of the switch and the like. · Steam condensate lines, closed heating and cooling systems, hydraulic tests rustproof inner surface of the device and after the test. Rust-proof transport and storage of parts and equipment. · Use powder using dusting, spraying and other methods of gas blasting guns. 10 g powder per 28 liters sealed space may be protective. ? When wet rust in water plus 0.25% (by weight) of the powder. To improve the wettability of the metal surface, the wetting agent may be added Goethe S-5, in an amount of 0.5% by weight of the powder. Methods and water plus 0.75% (by weight) of powder made of rust-proof liquid, by brush, spray, rinse, soak construction, after construction, should be stored in a confined space. · In the relatively harsh environment, the amount should be increased. · In general, the powder without clear, but before soldering, or other high temperature treatment, the application of compressed air or water rinse. Packaging and storage · Packaging: 2.27 kg, 22.7 kg, 45.4 kg drums. · Storage: dry and cool place, sealed, the temperature is below 66oC. Storage period of 2 years
