G80 Alloy Lifting Chain needs surface treatment. The reason is self-evident. After all, the general chain works outdoors, and the operation intensity is very high, especially in the hot summer, when the big sun is always directly exposed. Without surface treatment, the phenomenon of corrosion and rust is very likely. There are three general treatment methods: polishing, blackening, and galvanizing. Here is a look at polishing, let's take a look.
Surface treatment method of polished lifting chain: (1) Put sodium nitrite, water or leather into the stainless steel barrel to perform high-speed grinding and polishing, so that the wear-resistant material causes spray welding to the surface of the 80-level chain, and the surface Coming brighter. (2) Grinding and polishing can not improve the precision of the specifications of the steel parts or the precision of geometric shapes, but it can make the surface quite shiny. (3) The purpose of putting sodium nitrite is to avoid the rust of the 80-level chain for a short time (after drying, it is generally not easy to rust under the standard of dry and natural ventilation for half a month). The 80-level chain must be hoisted by polishing Dry first, apply oil after drying, and then pack.
The process of polishing the G80 Alloy Lifting Chain is still relatively complicated. Customers who require it can contact us.
