Description: Kay UNITA stainless steel passivation solution Cheung 4000, and general physical anti-rust oil is essentially different. It belongs to the chemical properties of rust certified by SGS and MSDS reports, proving to be eco-friendly stainless steel passivation solution. Its operating process is relatively simple, easy to use, stable performance. Has been far more than counterparts all anti-rust products, the key is that the product is circulating type of medicine, the price is cheaper, it is the size of the companies to buy, it has been appreciated by many customers. Features and Benefits: A passivation workpiece size will not have any change, the workpiece cleanliness color will not change. Liquid can be reused; Second, the process has a stable performance, surface treatment consistent characteristics. Process by this product after the best available anti-neutral salt spray test 200 hours does not rust; third, easy to use, you can simply soaked, and without specific machining equipment and strict processing conditions, reduce costs ( more than two-thirds of the cost savings outward processing); four, passivation solution is a stable agent, will not break down, no precipitation, easy to transport, storage period of three years, used with the check; Fifth, the product is then natural extracted from plant matter, automatic biodegradable waste. Safety and environmental protection, has passed the SGS certification; adapt material: For all ferritic and martensitic stainless steel (405,430,434, XM27,403,410,420J2,420F, 440,630,631,632,416, 1Cr17,410, 1Cr13,1Cr12,0Cr13,2Cr13,3Cr13,4Cr13 etc.) chemical rust. Conventional process: degreasing --- over the water over the water --- --- --- passivation coordinated --- --- over the water and over the water --- --- over pure water - - Drying --- Packing Note: The process can be adjusted according to the actual situation of the use of methods: Cheung 4000 passivation solution to dope use, normal temperature (optimum 60 to 70 degrees). The workpiece surface clean and free of oil into the product temperature 80 ± 5 degrees soak 15-30 minutes, - rinse with water, then put complexing agent treatment temperature of 60 to 70 degrees, the time 15 minutes After removal, - rinse with water, then soaked in pure water and drying to packaging from 1 to 3 minutes. ? If the workpiece shape complex, difficult rinse after passivation, it is recommended to increase the use or NaCO3 5% NaOH solution and water for 1-2 minutes before the technology bubble, then rinse and then soak the workpiece water, the better .
