Hardware shrapnel belongs to metal stamping parts. With the help of the continuity of metal shrapnel, it plays a high-quality switch between the operator and the product.
Regular cleaning of hardware shrapnel can prolong the service life of hardware shrapnel and reduce production cost. How to clean hardware shrapnel? There are the following methods for cleaning hardware shrapnel:
1. The grease, oil and lubricating oil pollution of the hardware shrapnel should be wiped dry with soft cloth or paper and washed with neutral detergent or ammonia solution or special washing drugs; fingerprints should be cleaned with alcohol or organic solvents (ether and benzene), and then washed with water after being dried with soft cloth; The bleach and the seed acid adhere to wash immediately with water, soak in ammonia or neutral carbonate soda water solution, and then wash with neutral detergent or warm water.
2. The welding of metal shrapnel is discolored by heat, washed with 10% nitric acid or hydrofluoric acid solution, neutralized with ammonia water carbonated soda solution, and then washed with water for stainless steel spring, which is specially used for washing drugs; organic carbides are attached and soaked in hot neutral detergent or ammonia solution, and then washed with detergent containing weak grinding.
3. The label and film should be washed with warm water and weak detergent; the dust and easy to remove dirt should be washed with soap, weak detergent or warm water; the adhesive component should be alcohol or organic solution; The rust caused by the surface contamination of the metal shrapnel should be washed with nitric acid (10%) or grinding detergent – too many rainbow lines with special detergent, detergent or oil, and warm water neutral detergent should be used when washing.
The precautions for cleaning hardware shrapnel are as follows:
1. When washing, please pay attention not to scratch the surface, avoid using bleach components and detergent containing abrasive, steel ball (roller brush ball), grinding tools, etc. in order to remove the washing liquid, wash the surface with clean water at the end of washing.
2. When cleaning stainless steel products, the surface damage of stainless steel should be minimized to make the stainless steel products look more comfortable and comfortable to use.
3. In our daily life, we often see stainless steel, although it will not rust, but the surface also often appears stains. The spring should be a little more difficult than stainless steel.
