Analysis of the method of removing rust by a hardware parts processing company

According to the hardware parts processing company, precision parts or accessories such as bearings, etc., due to inventory conditions or improper rust prevention, can basically not be processed by mechanical methods, and chemical pickling will damage the accuracy of the parts. Based on many years of processing experience, Haishuoda Technology has summarized some methods for removing rust, which will not damage the workpiece, the parts will not change, and will not be corroded.

Rework or repair of high-precision parts. Floating rust is generated on the surface of parts due to improper inventory or transportation. The use of Kelin-306 can perfectly remove the floating rust and ensure the original accuracy;

1. Soaking cleaning process

1 The hardware parts processing company analyzes and puts the professional cleaning stock solution into the tank (it is better to use a plastic or stainless steel tank, which can reduce the penetration of iron ions into the stock solution and reduce the service life);

2 Use electric heater to heat to 40-50 degrees and keep it, normal temperature can just need to extend the time;

3 Immerse the workpiece in the tank;

4 If you need to further improve the efficiency, you can add a circulating pump to stir the tank liquid;

5 After the rust is completely dissolved, take out the workpiece and rinse with water-based anti-rust agent;

6 Dry or dry naturally after rinsing, or directly dehydrate and prevent rust;

7 When necessary, carry out comprehensive rust prevention and transfer to the next process.

2. Wipe cleaning process

1 According to the hardware parts processing company, repeated wiping with a rag, this method is suitable for cleaning and rust removal of large equipment or workpieces;

2 After wiping, dry with hot air or dry naturally and apply anti-rust oil.
