The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tightly bound with a very strong transparent plastic bag. The outer layer of coated iron wire is wrapped with white braided cloth, and the outer layer of galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process. One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires.

The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling.

In the production process of redispersible polymer powders, polymer powders are polymer “solid” particles transformed from monomer emulsified droplets. Strictly speaking, these particles are not solid indeed, since the polymers considered here are thermoplastic, which will become solids only below a certain critical temperature, referred to as the glass transition temperature (T_g). Only above this temperature will the thermoplastic body lose all of its crystalline properties. However, since polymers are intertwined like nets, this kind of material is in fact still in a quasi-solid state.
