Hot dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to first pickling the iron and steel parts. In order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

We must have a certain understanding of the hexagonal network, we are swayed by the beautiful shape of the hexagonal network, not only the shape of the hexagonal network is very beautiful, in fact, the practical value of survival is very high. The relevant information of Shaojie should be very clear to know that the high speed road guardrail network, hexagonal mesh of all kinds of guardrail network, the value of the high speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball venues and landslides to take care of, but also to reach a very close utility.

Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?

Dog cage mainly by welding, spraying, injection molding, surface treatment, electroplating dog cage is made of high quality steel wire, dog cages are with plastic and plastic surface treatment, electrophoresis, chrome plating, galvanized, imitation gold, etc., according to the customer request processing, respectively, also can be customized to sample, dog cage assembly of compact structure, neat and beautiful appearance, make folding and remove the cage is more convenient and quick, won’t take up too much space.

1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

Now most people want to choose a few when choosing barbed wire material better thorn rope, but the special barbed wire the better, not right, it is important to choose which model is most suited to their own thorn rope,, although is very simple product, but in the use of these products are for specific situation is different, and has a different effect, Maybe now consumers do not have too much concept of blade barbed rope, in fact, such barbed rope products have a higher safety factor.

Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, and the steel with chemical corrosion resistance is called acid resistant steel. And galvanized wire has good toughness and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields.

3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
