Precision parts processing or accessories, such as bearing and so on due to improper inventory or rust prevention, can not be processed by mechanical methods, and chemical acid washing will damage the precision of the parts. According to many years of processing experience, HSD has summarized some methods of rust removal, which are non-destructive to the workpiece, parts will not change, and will not be corroded. High precision parts rework or repair. Due to improper storage or transportation of parts surface rust, the use of Colin-306 can be very perfect to remove rust, and ensure the original accuracy;
One, soaking cleaning process
1. Add professional cleaning solution to the tank (preferably with plastic or stainless steel tank, which can reduce the iron ion infiltration into the original solution to reduce service life);
2 heating the electric heater to 40-50 degrees and keeping it at room temperature.
3 the hardware processing parts are soaked into the grooves.
4 if further improvement is needed, the circulating pump can be added to agitate the tank.
5 after the corrosion is completely dissolved, the workpiece is removed and rinsed with water based rust inhibitor.
6 rinse naturally after drying or drying, or directly dehydrate and rust.
7 when necessary, carry out comprehensive rust prevention and transfer to the next process.
Two, cleaning and cleaning process
1 wipe repeatedly with rag cloth. This method is suitable for cleaning and derusting large equipment or workpieces.
2 after wipe, use hot air to blow dry or dry naturally, then apply anti rust oil.
