Application of zinc chloride

[Application] Industrial zinc chloride is one of the important chemical raw materials, mainly used as dehydrating agent and catalyst in the organic synthesis industry; mordant, mercerizing agent, sizing agent and preservative in the dyeing and weaving industry; making dry batteries, activated carbon, and tempered paper ; Used as a wood preservative, welding liquid and petroleum purifying agent

As a cathode corrosion inhibitor, zinc salt rapidly forms zinc hydroxide deposits in the cathode micro-area with higher pH, which covers the surface of the cathode and slows down the process of cathode depolarization

Zinc salt alone also has a certain corrosion inhibition effect, but the film formed by it is not very strong, and it is generally used in combination with other agents
