How to clean contact metal shrapnel

The contact metal shrapnel is a metal stamping part. With the help of the conductivity of the metal shrapnel, it acts as a high-quality switch between the operator and the product. Regular cleaning of the metal shrapnel can extend the service life and reduce the production cost. How to clean the metal shrapnel?

There are the following cleaning methods: 1. The fat, oil, and lubricating oil in contact with the hardware shrapnel are contaminated with a soft cloth or paper and then washed with a neutral detergent or ammonia solution or special detergents; fingerprints, with alcohol Or organic solvent (ether, benzene), wipe dry with a soft cloth and then wash with water; bleach and kind of acid attached, rinse immediately with water, soak in ammonia or neutral carbonated soda aqueous solution, and then wash with neutral detergent or warm water . 2. The welding contacting the hardware shrapnel will be discolored by heat, wash with 10% nitric acid or hydrofluoric acid solution, then neutralize with ammonia water, carbonated soda light solution, and then wash the stainless steel spring with water--special use for washing medicine; organic carbide adheres and soaks in the heat The neutral detergent or ammonia solution is then washed with a weakly abrasive detergent. 3. Use warm water and weak detergent to scrub the label and film; use soap, weak detergent or warm water to clean the dust and dirt easily; use alcohol or organic solution for the binder component; surface pollution in contact with the metal shrapnel Use nitric acid (10%) or abrasive detergent to wash the rust caused by objects-use special detergents to cause excessive rainbow patterns, use detergents or oils, use warm water detergents when washing. The precautions for cleaning contact hardware shrapnel are as follows: 1. Please pay attention to avoid surface scratches when washing. Avoid using bleaching ingredients and detergent containing abrasives, steel balls (brush roller balls), grinding tools, etc., in order to remove the detergent , At the end of washing, rinse the surface with clean water. 2. When cleaning stainless steel products, try to ensure that the damage on the surface of the stainless steel is minimized, so that the stainless steel products look more comfortable and comfortable to use.

3. In daily life, we often see that although stainless steel does not rust, stains often appear on the surface. Stainless steel springs are a bit more difficult than ordinary stainless steel, so some small tricks should be used to deal with them.
