Advantages of stainless steel passivation solution: not changed ▲ passivation any size and color of the workpiece, the effective protection of the beautiful appearance and accuracy of the workpiece; ▲ free wash effect, excellent corrosion resistance to effectively prevent the generation of hydrogen embrittlement; ▲ cost inexpensive, liquid can be reused, implement anti-rust grade material from the times become strong; the ability to engage in highly corrosive ▲ passivation after 430 best material up to 500 hours, more than 420 materials 72 hours. Its excellent corrosion resistance can reach the world advanced level; ▲ simple process operation, no special operating environment requirements, non-toxic low corrosion, general plastic containers can be used, the device is easy to configure; ▲ safety and environmental protection, odorless, environmentally friendly operation ; ▲ does not affect the conductive properties of the material does not change the material composition, does not affect the spray-binding. Applications: Widely used in various types of passivation treatment SUS400 series stainless iron, especially for small precision complex parts large passivation. Such as screws, axle pin, precision mechanical transmission parts, communications equipment and other fasteners and other passive anti-corrosion treatment. Conventional process: the treated object - degreasing - over water - passivation - mobile water rinse - with a bit processing - over water --- bubble pure water - drying or dry Note: the process can be increased according to the actual situation Less use: 1, the product is dope use, normal temperature (optimum 70 to 80 degrees). 2, 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 for 15 After the minutes out, rinse with water, then soaked in pure water and drying to packaging from 1 to 3 minutes. 3, if the complex shape of the workpiece, it is difficult passivation after washing clean, it is proposed to increase the use soak water craft before or NaCO3 5% NaOH solution and 1-2 minutes, then rinse and then soak the workpiece water, the effect is more Good.
