What are the reasons for the oxidation of Dongguan hardware stamping parts?

In the processing of metal stamping parts, the materials used in stamping parts, such as stainless steel, iron, aluminum, brass, alloys, etc., are prone to oxidation in the later stage. What is the cause? How to avoid it? Dongguan hardware stamping parts hardware manufacturer hardware tells you. Oxidation of stamping parts is generally caused by the metal stamping parts being exposed for too long in an environment that is relatively easy to oxidize before packaging, or when touching the stamping parts when there is sweat on the hands, because the sweat contains a certain acidity, which makes the stamping parts happen. During the processing of metal stamping parts, a special liquid was accidentally dropped, such as baking soda solution, rainwater, saliva, etc., things with acidic substances; when packaging metal stamping parts, the packaging must be tight. Do not breathe, so as to avoid oxidation reaction with the outside; The following two methods are recommended to avoid; The method of blackening the surface of the stamping part includes the following steps: (1) After cleaning the surface of the metal stamping part, add it to the vacuum chamber, and After the temperature in the vacuum chamber rises to 150~200℃, heat preservation treatment is 30~40min, then silane gas is introduced into the vacuum chamber, the temperature of the vacuum chamber is raised to 350~380℃, after 6~7 hours of heat preservation treatment, press Take out the parts and cool to room temperature; (2) Put the stamped parts processed in step (1) into the blackening liquid, take it out after 10-15 minutes of blackening treatment, and clean it to obtain the finished product. This method of blackening the surface of stamping parts is simple to operate and low in cost. The stamped parts produced have a uniform black surface, and the film has excellent corrosion resistance, and the blackening film will not easily occur during use. The phenomenon of shedding and excellent wear resistance greatly improves the quality of stamping parts. Therefore, hardware recommends that you wear gloves when stamping or packaging metal stamping parts, and keep your hands away from direct contact. After the stamping parts are produced, put them in an environment that is not easy to oxidize. After the iron parts and carbon steel stamping parts are produced, , It can also be cleaned with anti-rust hydrocarbon cleaning agent to achieve the purpose of anti-rust.
