The application fields and usage methods of rust proof bags. Rust proof bags have good plasticity and can overcome the weakness of insufficient protection of existing rust proof products. They have good transparency and the effective protection time of the product can reach 1-3 years Age. Rust proof bags are a new generation of innovative high-tech products in the field of metal anti-corrosion. After sealing the rust proof metal products in a rust proof bag, the contents of the bag VCI Start sublimating and evaporating rust proof gas factors, spreading and penetrating towards the rust proof surface. By adsorbing objects to form a single molecule thick molded body, various factors that cause rusting on the surface of the rust proof body are blocked, effectively preventing rusting. Rust proof bag products are products that combine modern film technology and gas-phase (VCI) technology PE Resin and VCI Special processes of blending, co extrusion, and blow molding. It is a new generation of anti rust packaging material that is transparent, intuitive, has good barrier properties, has a long anti rust period, is easy to use, and is economical and environmentally friendly. VCI A bag is a bag formed by pressing a diaphragm mold. When packaging, the product is directly placed in the bag and sealed to form a relatively sealed bag. Without a certain seal, rust prevention can be achieved.
The main application areas of rust proof bags are:
1. Automotive and motorcycle parts
2. Mechanical parts, medical machinery, precision instruments, cast iron parts, aviation parts
3. Various hardware and powder metallurgy
4. Various electric tools, measuring tools, and cutting tools
5 . Bearings, clutches, motors, valves
6. Carbon steel, alloy steel, cast iron, phosphorus steel, nitride steel, blue steel, powder metallurgy, oriented silicon steel, non oriented silicon steel, etc.
Precautions for using rust proof bags:
1. The volatility of weather resistant corrosion inhibitors increases with temperature, so they cannot be stored and transported in environments above 40 ° C. The cooled heat source and hot metal package.
2. In environments with relative humidity above 75%, the corrosion inhibition effect of gas-phase corrosion inhibitors decreases. When packaging finished products, the environmental humidity should not exceed 75%, and moisture and gas-phase anti-corrosion materials should be avoided during storage and transportation. Can be used together with desiccants.
3. Before packaging, keep the packaged items clean and free of fingerprints. Packaging personnel must wear gloves when handling metal objects and packaging processes.
4. The rust proof bag must be used within 180 days after purchase.
5. The surface of rust proof products must be clean and dry before they can be packaged in rust proof bags. Then wrap and seal with rust proof film at room temperature. If the oil is packaged, it must be checked for any impurities in the oil S、Cl Waiting for chemical substances. Otherwise, it will be VCI The effectiveness has a negative impact.
6. Wear clean gloves when packaging and do not touch non rusting items with bare hands.
7. If the rust proof material has protrusions or edges, be careful not to puncture the film. In case of accidental damage, the wound must be promptly sealed with industrial tape to ensure sealing.
8. When packaging with rust proof bags, the workplace should be kept away from strong corrosive substances such as acids, alkalis, and corrosive gases.
