2. The cleaning agent used for cleaning should have no effect on the binding force of the coating and no corrosion on the matrix.

There are many kinds of galvanized solution, which can be divided into cyanide plating solution and cyanide plating solution. Cyanide galvanizing solution has good dispersion and covering ability, coating crystallization is smooth and fine, simple operation, wide application range, has been used in production for a long time. However, because the plating solution contains highly toxic cyanide, the gas escaping in the plating process is harmful to the health of workers, and the waste water must be treated strictly before discharge.

According to the galvanized iron wire manufacturer, galvanized iron wire is the selection of excellent low carbon steel, through drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized, cooling and other processes. Galvanized iron wire should pay attention to the following points in the use process:

Construction welding net work wall insulation project using galvanized welding network in wall insulation and rust engineering project plays a necessary role, wall painting batch putty network is divided into two kinds: this is galvanized welding network; Another is to change the wire drawing wire welding mesh, according to the provisions of the region, construction enterprises to carry out effective material selection. Construction welded wire mesh new mink cage new mink cage grommet see more 1 inch, from silk in 2 mm up and down, management method is simple and easy, a mesh surface bright and clean and is not easy to scratch mink, galvanized welded wire online zinc quantity proportion, it is not easy to rust, new mink cage up more convenient, mink settled in natural environment more comfortable, the price also is higher than before the same specifications of the mink cage competitive many, But the overall character is not harmed at all, it is stronger.

1. The diameter of the raw material and the thickness of the diameter are directly affected;

If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.

In reinforced concrete structure, the crack width of cold wire drawing is smaller than that of circular steel bar or even that of hot rolled thread bar. So cold wire drawing is more popular in the construction industry. The material for cold drawing is made of steel bars and can be simply explained how it is made, that is, its production process is simple. It’s based on steel bars, which are constantly stretched evenly, stretching the bars into something very thin, like wire drawing, without plasticity.

The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.

When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.

Barbed rope factory not only provides the sales of blade barbed rope, including the subsequent construction is also contracted, and the construction price is particularly different.
