Tapered roller bearings the semi-finished and finished products daily rinse with sodium nitrite solution

Methods commonly used inter-process rust bearings are the following:
I. dip concentrated solution of sodium nitrite
After washing the product, immersed in a 15% -20% sodium nitrite and 0.6% sodium carbonate solution, and paired tapered bearing then it is stacked up. In this way short of its rust, generally only kept 14 days, but in the rainy season, due to wet weather, keeping only 2-3 days to be reprocessed, it takes labor and money.
Two. Immersed in the tank rust
The bearing trap immersed in 5% aqueous solution of 0.6% sodium nitrite and sodium carbonate, the rust is still good, but a lot of rust tank and other equipment, take up a lot of space management is not easy.
Three. Oiled
Like anti-rust oil painted like a finished product. This method must be cleaned before the next step, more trouble.
New rust process method description:
After the manufacturers double row tapered roller bearing together with related research, years of practice show that for inter-process rust multiple improvements to the use of shower spray type rust better. Roller rust initially conducted the trial, the semi-finished and finished products daily rinse with sodium nitrite solution, three months after testing results found no corrosion, the use of semi-finished products now bearing trap rust shower jet, the effect is also true. Spray rust leaching process is relatively simple, the method is as follows:
A. Process method
