Rolling bearing new anti-rust process method is introduced

After years of research, together with the relevant manufacturer's production practice shows that the process between the antirust improved many times, in the spraying antirust effect is better. Initial trial was carried out on the roller rust, semi-finished products and finished products with sodium nitrite aqueous wash once a day, after 3 months to sample the results found no rust, now on bearing trap semi-finished products used for spraying antirust, effect also is so. Spraying antirust process is simple, the method is as follows: 1. What construction according to the intermediate storage device, the establishment of a middle library, ground with cement floor, can be set up between a footpath, about 1. 5 m, which is used to pass bearing ring car. Put a deposit at the end of the channel sodium nitrite solution pool, solution formula for 5% Add 0 10% sodium nitrite. 6% sodium carbonate, and on the ground do HuiShuiGou, piled on the floor on both sides, and then the bearing ring between each pile bearing ring with 0. 6 m in the hallway. To tell the middle library design is about 64 m2, the sodium nitrite solution pool for 1 m3. 2. Processing method with sodium nitrite solution every morning washing time, absorption in aqueous solution by water pump from pools to come out, the rubber pipe into the shower, wash bearing ring like spraying. Rinse water solution by HuiShuiGou flow back into the pool, pool in the end of the HuiShuiGou top, made a fine wire and gauze filter with grime textile ash content into the sink. Middle library should be with good quality and clean. Pools of solution once every two days test, according to the test results to supplement, pool solution of replacement period, according to different months - 4 September thoroughly change once every two weeks, October - The following year in March, change once a month. Conclusion: spraying type anti-rust, management more convenient and saving labor, the middle library used two rust is not complete, now with a person also can and do other work, from the antirust effect is also significant. In March 2003 to 7002136 and 3620 roller of more than 4000 grain, adopted spraying type anti-rust, nearly more than a year to remain very light, no rust. In addition to the consumption of chemicals also has a lot to save, the roller workshop takes a month more than 4000 kilograms, sodium nitrite and now only 200 kilograms, save nearly half. Spraying type anti-rust method after the relevant manufacturers to test and use in recent years, proof of the cycle, large, batch number, long bearing semi-finished products is very suitable.
