hot dip galvanized iron wire
is the most widely used
一、Continuous hot dip galvanizing
A high aluminum zinc coating (55% Al, 45% Zn, a small amount of silicon) and a Galfan coating with a small amount of rare earth added to the Zn-5% Al alloy are a series of continuous coatings, which are widely used.
In the case of corrosion resistance, high aluminum zinc coating is generally used (but its plasticity is poor);
when plasticity is required, Galfan is selected. If surface quality is required and it is not required to be maintained for a long period of time, zinc plating is generally selected.
The most difficult to handle in general plating is silicon killed steel. Silicon killed steel incorporates silicon during the deoxidation process.
This method of adding silicon has a certain influence on hot dip plating. Because the silicon content will affect the thickness, appearance quality and adhesion of the zinc coating of steel products, this is extremely important in the exploration of the potential market of zinc coating.
It is currently being studied to add a small amount of nickel to the electroplated steel to eliminate the influence of silicon content.
At present, the application of silicon killed steel in different countries is different, such as the United States is used less, in the United Kingdom is more common, France more.
Different characteristics of galvanized iron wire
with different technical systems
The biggest feature of galvanized iron wire manufacturers is that the surface is smooth and bright, but the moisture will affect the brightness of the galvanized wire. Therefore, it is necessary to pay attention to avoid moisture when storing. The best way is to set up a shelf on the ground for plating. The zinc wire is isolated from the ground so that it is not affected by the surface moisture. It is also necessary to pay attention to the weather changes and avoid the rain on the galvanized wire.
The galvanized wire has good toughness and elasticity, and the maximum amount of zinc can reach 300 g/m2. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, wire mesh, highway fences, product packaging and daily civil use.
Galvanized wire is divided into hot-dip galvanizing, cold-galvanizing is electro-galvanized, hot-dip galvanizing is the highest price, and electro-galvanized price is low. Hot-dip galvanizing is not easy to rust, and electro-galvanizing is prone to rust.
