Since the method of hot – dip galvanizing was developed by the French chemist Paul Jacques Malouin in 1742, and then improved almost a hundred years later by another Frenchman-Sorel, in the process little has changed dramatically.
First, the products in need of galvanizing, must pass the preparatory stage. They are degreased, washed, etched with a solution of hydrochloric acid, washed again, and then flux. The products are dried using hot and cold air streams, and then cooled to the required temperature.
After these procedures, they get to the main shop. Objects immersed in one of the iron baths with hot zinc. Such baths are suspended on iron hooks or moved in a trolley on rails to quickly move them around the room. The product is placed in a zinc solution for a period of three to ten minutes. The rotating drum allows you to evenly distribute the zinc coating on the surface, filling all the cavities and holes. After that, the product is dried, first in the open space, then-in the warehouse. Specialists check the result for compliance with the standards, after which the hot-dip galvanizing process is considered completed.
Above each bath there are filters that cool the hot air and purify the emissions before they enter the atmosphere. The alarm system monitors the situation in the shop and constantly makes the necessary measurements, in case of danger gives an alarm signal. All procedures are controlled remotely using an electronic shield, and each new stage is independent of the previous one.
In the end, the resulting products are not subject to corrosion, and, in addition, do not need painting for many years, being able to independently heal minor damage.
