Maintenance methods for powder metallurgy mainly include the following aspects:
Rust-proof treatment:
Rust-proof oil: After the production of powder metallurgy parts is completed, anti-rust oil is usually sprayed on the surface to prevent rust during storage and transportation. Parts sprayed with anti-rust oil can remain rust-free for one or two years in a sealed state.
Blackening treatment: This is a chemical surface treatment method that forms an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. This method is often used when the appearance requirements are not high.
Storage conditions:
Environmental control: The storage environment should be dry, clean, ventilated, with moderate temperature, and no fire source. Metal powders should be stored separately from acids, alkalis, corrosive and flammable, explosive, and active chemicals to avoid chemical reactions or cross-contamination.
Packing method: Use appropriate packaging and sealing materials, such as sealed thick plastic bags, and add desiccant to the packaging to prevent moisture and contamination.
Operation Specifications:
Safe Operation: Operators should wear protective measures, such as protective gloves, protective masks and protective glasses. The company should strengthen employee safety training to make them understand the characteristics and safety precautions of metal powders.
Fire and Explosion Prevention Measures: Some metal powders are highly active and have the risk of combustion and explosion. Therefore, appropriate fire and explosion prevention measures need to be taken, such as storing them in explosion-proof containers and isolating them from fire sources.
Quality Inspection:
Regular Inspection: Metal powders are regularly inspected and tested for quality to ensure that they meet the specified standards.
