Description
Technical Field
[0001] The invention relates to the technical field of anti-corrosion treatment, in particular to an anti-corrosion treatment device for an impact-resistant fastener. Background Art
[0002] The impact-resistant locker is a mechanical device specially designed to withstand impact loads and maintain a tightened state. It can maintain the tightening force in a high-impact environment and prevent loosening or falling off due to factors such as vibration and impact. It is widely used in industrial fields that require high reliability and stability, such as automobiles, aerospace, heavy machinery, etc.
[0003] The impact-resistant lock has the characteristics of high strength and corrosion resistance. The anti-corrosion treatment of the impact-resistant lock is the key link to ensure its long-term stable operation. The main purpose of the anti-corrosion treatment is to form a protective layer on the surface of the lock to isolate or slow down the corrosion of the lock by external corrosive substances. The following are some common anti-corrosion treatment methods: 1. Metal plating technology: Hot-dip galvanizing: immerse the lock in molten zinc liquid to make the zinc and the surface of the lock metallurgically bond to form a uniform zinc coating; electrogalvanizing: using the principle of electrolysis, a thin and uniform zinc coating is deposited on the surface of the lock. The electrogalvanizing process is relatively simple and the cost is low; mechanical galvanizing: Through the combination of mechanical impact and chemical deposition, a uniform zinc coating is formed on the surface of the lock. This method combines the advantages of physics and chemistry, with strong coating bonding and good corrosion resistance. In addition to zinc plating, chrome plating, nickel plating, cadmium plating and other metal coatings can also be selected according to specific needs; 2. Coating technology: Coat one or more layers of anti-corrosion coating on the surface of the lock to isolate the corrosive substances from direct contact with the lock. Common coating materials include paint, organic coating, inorganic coating, etc.; 3. Passivation treatment: Form a dense passivation film on the surface of the lock by chemical or electrochemical methods, thereby improving the corrosion resistance of the lock.
[0004] At present, when the existing technology performs electroplating anti-corrosion treatment on the lock, the lock is usually placed on a plating rack and then put into a plating tank for electroplating.
