2, performance characteristics. Zinc coating is thick, fine crystallization, uniform and no pores, good corrosion resistance; Is pure, the zinc plating layer in acid, alkali corrosion slower, such as fog Eng effectively protect tight sand-fixation matrix, the galvanized layer formed after chromate passivation, color white, army green, beautiful and easy, have certain adornment sex, because the galvanized layer has good ductility, and therefore can be rushed, rolling, cold bending and forming and not damage the coating.
The national standard on the use of wire mesh standards have certain requirements, diameter and mesh size matching use, rather than simply diameter size, on the plaster layer to use is mesh should not be greater than 20×20, diameter is not easy to be less than 1mm, light selection diameter is not much significance, choose 40×40×0.9 and choose 10×10×0.6 wire mesh, Which is better, I’m afraid is 10×10×0.6.
Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.
Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.
Large hexagonal net is called stone cage net, mainly used for mountain protection, hydraulic construction, etc. Small wire hexagonal net is used as a good breeding material, the twisted flower hexagonal net in the welding of the iron frame get on the hexagonal net burning welding coops, pigeonholes, rabbit cages and other cage, hexagonal net is the best breeding material with the net.
Titanium and titanium alloy with light weight, high strength, corrosion resistance and many other characteristics, titanium and its alloy not only in aviation, aerospace industry has a very important application, and has begun to chemical, petroleum, light industry, power generation, metallurgy and many other civil industrial sectors are widely used. However, titanium and titanium alloy are smaller than steel in terms of hardness and strength. The shortcomings of titanium alloy wire made of titanium alloy in terms of hardness limit its breadth and depth of application.
