Hot-dip galvanized products in the production process, involving a number of links and factors, each step needs to be strictly controlled to ensure the quality and performance of the final product. The following are several important aspects that need attention in the production process of hot-dip galvanized products: First, the choice of raw materials is crucial. High quality steel and zinc materials are the basis to ensure the quality of hot dip galvanizing products. The steel should have good plating ability, and the surface should be clean, free of oil and rust. Zinc material should be selected with high purity, less impurities of high quality zinc ingots to ensure the uniformity and adhesion of the galvanizing layer.

Zinc material should be selected with high purity, less impurities of high quality zinc ingots to ensure the uniformity and adhesion of the galvanizing layer.

Secondly, the pretreatment process has an important impact on the quality of hot-dip galvanizing products. Pretreatment mainly includes steps such as oil removal, rust removal and cleaning. These steps must be strictly carried out to completely remove impurities and contaminants from the steel surface and provide good conditions for subsequent galvanizing treatment.

In the galvanizing process, the temperature and immersion time of the zinc solution need to be precisely controlled. Too high or too low temperature of zinc liquid will affect the quality and thickness of galvanized layer. Too long or too short immersion time may also lead to uneven galvanized layer or defects. Therefore, the operator needs to pay close attention to the zinc liquid temperature and immersion time, and adjust according to the actual situation.

In addition, the maintenance and maintenance of hot dip galvanizing equipment is also the key to ensuring product quality. Equipment should be inspected and repaired regularly to ensure that it is in good working condition. At the same time, the cleaning and maintenance of the equipment can not be ignored to avoid impurities and pollutants on the galvanizing process.

Finally, quality control and testing is an indispensable part of the hot-dip galvanizing production process. Through strict quality control standards and testing means, problems in the production process can be found and solved in time to ensure the stability and reliability of product quality. This includes quality checks on raw materials, semi-finished products and finished products, as well as monitoring and adjustment of key parameters in the production process.

The use and protection of stainless steel plate

After the installation of the stainless steel plate, it is necessary to tear off the film in time, and then, for the stainless steel plate should also use a special stainless steel cleaner for cleaning, the common way is to use talc powder (double fly powder) from beginning to end after wiping again, it is best to use clean water to wipe again, be sure to wipe dry. The reason why it is necessary to tear off the film in time is to avoid the phenomenon of retaining the glue for too long or the aging of the film cannot be torn off in severe cases.
