How the door is processed with powder coating

Powdered processing technology of doors mixture

Processing technology appeared several decades ago. Steel doors are preliminarily cleaned and prepared for the process.

A powder consisting of a mixture of metal particles and coloring pigments, by electrostatic spraying is applied to the surface. After this, the doors are thermal processing in a high -temperature furnace heated to 2000. In the furnace, the powder melts and spreads on the surface of the metal, forming numerous uneven tubercles and multi -colored spots. As a result, the surface is covered with a polymer. After cooling, the steel sheet is covered with special thermal varnish, which is also dried in a stove at high temperature. Lark application increases the life of the door. Such doors are often installed in the bathroom.
