Advantages and application analysis of galvanized iron chain
Galvanized iron chain is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. The galvanized iron chain is to pickle the iron chain first. In order to remove the iron oxide on the surface of the iron chain, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the galvanized iron chain. into the hot dip bath.
Galvanized iron chain has the advantages of uniform coating, strong adhesion and long service life. Galvanized iron chain is hot-dip galvanized on the basis of welded iron chain (that is, the zinc is dissolved in a zinc pot, and then the iron chain is immersed in liquid zinc for a period of time to be taken out, and then cooled and dried). Make the inner and outer walls of the iron chain have a layer of zinc attached at the same time. Galvanized iron chains are generally used for the transportation of low-pressure fluids (ie, water, liquid gas).
With the development of today's society, the types of chain products are also constantly innovating. The use of chains should be widely used in many industries. In food machinery, chain products are mainly used in chemical, food, cleaning, silk reeling , environmental protection and other machinery industries. Chain drive is a widely used mechanical drive in medical machinery, rubber machinery, printing and dyeing machinery, electronic equipment, sewage treatment equipment, automated conveying equipment, etc.
