Description: Kai Chun Union stainless steel passivation solution 4000, this product with the general anti-rust oil or sealer is essentially different. After the workpiece into the passivation solution soak in the workpiece surface micro-chemical reactions, can form a protective film on the surface, to improve corrosion resistance, to achieve the effect of long-term rust. Advantages of stainless steel passivation solution: 1, the passivation workpiece size will not have any change, the workpiece cleanliness color will not change. Liquid can be reused. 2, passivation does corrosion ability, optimal material 410 up to 100 hours, 150 hours more than 420 materials. Its excellent corrosion resistance can reach the world advanced level. 3, passivation solution is a stable agent will not decompose, does not precipitate, easy to transport, storage period of three years, used with the check. 4, the product is then extracted from natural plant materials, auto-biodegradable waste. Safety and environmental protection, has been certified by SGS. Applications: apply to 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.) passivation rust. Usage: 1, Jun 4000 passivation solution to dope use, normal temperature (optimum 70 to 80 degrees). The workpiece surface clean and free of oil into the product temperature 80 ± 5 degrees soak 15-30 minutes, 2, rinse with water, then put complexing agent treatment temperature of 60 to 70 degrees, the time for 15 After the minutes out, 3, rinse with water, then soaked in pure water and drying to packaging from 1 to 3 minutes. 4, if the shape of the workpiece complicated to rinse clean after passivation, it is recommended to increase before the technology bubble water or NaCO3 using 5% NaOH solution and 1-2 minutes, then rinse and then soak the workpiece water, the effect is more Good.
