The method of antirust generally used in the bearing process are the following:
Soaked in rust-proof tank
Bearing trap immersed in 5% sodium nitrite and 0.6% sodium carbonate aqueous solution, anti-corrosion effect is still good, but a lot of rust-proof tank and other equipment, to take up a lot of space, the management is not easy.
2 dipping concentrated sodium nitrite solution
Cleaning products, immersion containing 15% -20% of sodium nitrite and 0.6% sodium carbonate solution, and then it stacked up. Ways rust shorter period of time, generally only for7-14 days, and in the rainy season, due to wet weather, only for 2-3 days must be reprocessed, it takes labor and money.
3 oiled
The same as the finished product coated with a similar anti-rust paint anti-rust oil. This method must be cleaned before the next process, more trouble.
New anti-rust process methods
Common research and related manufacturers, many years of practice showed that the anti-rust processes between a numbers of improvements to the shower spray anti-corrosion effect. The initial trials with roller rust-proof, semi-finished and finished products to rinse daily with the aqueous solution of sodium nitrite, three months after the test in results did not find corrosion, a shower spray anti-rust bearing trap semi-finished products, the effect.
