In order to further improve the quality of the chain, it needs to be galvanized, but the relevant solution needs to be configured before this.Before configuring the galvanized chain solution, you must make sufficient preparations, such as cleaning the plating tank, rolling and stabbing, measuring the volume and accurately calculating various materials.

    In the formulation of the zinc plating chain solution, since it does not contain a strong complexing agent, it has no masking effect on heavy metal impurities. This is because the purity of the material is required to be higher than that of cyanide zinc plating.However, zinc oxide should use over 98% industrial first-class product, and sodium hydroxide should use block, strip or flake solid alkali with a purity of over 95%.

    The plating solution used in the chain can not use liquid caustic soda, mainly because the liquid caustic contains too many impurities, which will seriously affect the quality of the process.If it is in the daily maintenance of the galvanized chain, liquid caustic soda can be used, but it should be noted that zinc powder or sodium sulfide must be used to remove metal impurities before entering the tank.

    All in all, the purity of the raw materials and the preparation method used for the solution of the galvanized chain must meet the relevant requirements, because it has a great impact on the process quality of the galvanized chain.In addition to galvanizing, galvanized chains must be insulated.

    The insulating material used for the galvanized chain should have outstanding chemical stability and good heat resistance; the favorite insulating method is the wrapping method, which is to use polyvinyl chloride insulating tape to wrap the parts that require insulation. The round rod can also be sheathed with a plastic tube of appropriate diameter.

    In addition, the insulation effect can also be achieved by painting the surface of the galvanized chain with an insulating coating. The galvanized chain needs to be painted with an insulating and anticorrosive coating after rust removal, degreasing, and drying.There is also a plastic coating method. After the surface treatment such as rust removal, oil removal, drying, etc., it is heated to 250 ℃ and inserted into the thermoplastic powder to prevent the plastic powder from melting and adhering to the galvanized chain to form a thin plastic film .
