In order to further improve the quality of the chain, it needs to be galvanized, but before this needs to be configured with the relevant solution. Before configuring the Car parking chain, it is necessary to make full preparations, such as cleaning the plating tank, rolling, measuring the volume and accurately calculating various materials.

In the formula of Car parking chain, because it does not contain strong complexing agents, it has no masking effect on heavy metal impurities, which is because the purity of the material is higher than that of cyanide galvanizing. The zinc oxide to use more than 98% of the industrial grade, sodium hydroxide to use more than 95% of the purity of the block, strip or flake solid alkali.

The plating solution used in the chain can not use liquid alkali, mainly because the liquid alkali contains too many impurities, which will seriously affect the quality of the process. If it is in the galvanized chain in daily maintenance can use liquid alkali, but pay attention to the need to remove metal impurities with zinc powder or sodium sulfide before entering the tank.

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

The insulating material used in the galvanized chain should have outstanding chemical stability and good heat resistance; The preferred insulation method is the wrapping method, which is the use of PVC insulation tape to wrap the parts that are required to be insulated, and the circular rod can also be covered with a plastic pipe with a suitable diameter.

In addition, the insulation effect can also be achieved by brushing insulating paint on the surface of the galvanized chain, and the galvanized chain needs to be brushed with insulating anti-corrosion paint after rust removal, oil removal, drying and other external treatment. There is also a plastic coating method, after rust removal, oil removal, drying and other external treatment, heating to 250 ° C and inserted into the thermoplastic powder, so that the galvanized chain to avoid plastic powder melting and adhesion, forming a thin plastic film.
