Large roll galvanized wire galvanized layer to do paint, the separation between each other and the baking temperature of the paint has a great relationship, after galvanized with alkyd paint, adhesion is no problem. Amino paint is made after galvanizing, and the adhesion of paint is not very good. Do 2 bottom 2 face, adhesion is ok, if 2 bottom 2 face is changed to 2 bottom 3 face, namely BESMEar a top paint more, baked more, detect adhesion 10 points is poor again, poor to can tear the paint from galvanized layer on the piece.
Large roll galvanized wire does not do the adhesion experiment of overheated galvanized powder spraying or fluorocarbons spraying, in a sealed or airless environment, non-metallic volatiles can corrode zinc coating; Zinc brittleness occurs in the base metal at temperatures above 230 degrees. And after powder spraying and fluorocarbon spraying are baked at high temperature and in a sealed environment, causing rapid corrosion of zinc, corrosion film produced by strange pine lead to coating adhesion fall, and even lead to the possibility of brittleness of steel wire.
Because galvanized iron wire products are given the pre-tension, so it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, crack from time to time, strong elasticity, ordinary steel grain and rebar are difficult to compare. The use of advanced galvanized light whole process, so the use of hot galvanized steel wire building, not only good anti-corrosion performance, but also beautiful and generous. Large roll galvanized wire has the characteristics of external lubrication, high dimensional accuracy, good equalization of zinc layer and strong adhesion.
