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.
Reverse twist: Twist the barbed wire in the opposite direction from where the nematocyst is wound around the main wire. It’s not twisted in one direction. It’s called the reverse twist.

There are many ways to choose the blade stabbing rope, and it is necessary to choose reasonably when choosing. Blade barbed rope is very good in the market reputation, and different types of blade barbed rope can play different roles, so how should we choose blade barbed rope? What are the main points?
Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
1. Cleaning: Soak the pre-treated steel wire in detergent to remove surface impurities and dirt.

If adult dogs touch noses with puppies out of affection, adult dogs touch noses with dogs that have more meaning in life. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
Annealed wire is a kind of soft iron wire made of low carbon steel by cold drawing, heating, constant temperature and heat preservation. The composition of the wire varies according to its use. It contains iron, cobalt, nickel, copper, carbon, zinc, and other elements. The hot metal billet is rolled into 6.5mm thick steel bar, that is, the wire rod, and then it is put into the wire drawing device to draw the wire of different diameter, and gradually reduce the aperture of the drawing disk, cooling, annealing, plating and other processing technology to make a variety of different specifications of the wire.
Because of the pre-tension given to the packaging and binding of galvanized wire, it has the excellent characteristics of low relaxation value, small stress loss, good stability after loading, not easy to deformation, no fracture, strong elasticity, ordinary steel lines and rebar are difficult to compare. The use of advanced galvanized finishing process, therefore, the use of hot-dip galvanized steel wire construction, not only good corrosion resistance, but also beautiful and generous. The product has the characteristics of smooth surface, high dimensional accuracy, good uniformity of zinc layer and strong adhesion.
Three, the use of different technologies
In order to pack and bind galvanized wire in the surface of the sedimentary layer to local removal of surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank. Moderate rates of foam formation may be harmless. Small, homogeneous particles of large denier present in the bath can stabilize the foam layer. Use activated carbon mat to remove surface active substance. Or through filtration to make the foam is not too stable, which are effective measures; Other measures should also be taken to reduce the amount of surfactant introduced. The electroplating speed can be obviously reduced by the addition of organic matter. Although chemical formulations facilitate high deposition rates, the deposition of organic matter does not meet the requirements of coating thickness, so activated carbon can be used to treat the bath.
Because of the corrosion resistance of zinc layer, can be applied to all kinds of environment, it is also very convenient to use, has been a more popular hardware products. Galvanized iron wire should pay special attention to the acyl wash, to slowly into the container, to prevent acid sputtering on the body, at the same time prohibit the water into, so it is easy to let the acid out, to learn to handle lightly, stacking should also be firm and neat. It can be widely used in construction, handicrafts and other daily civilian applications.
⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles.
The spring operating at high temperature requires that it can adhere to the elastic limit and good creep resistance at high temperature. In addition, the forming process and heat treatment process of spring steel wire should also be considered. Cold drawn spring steel wire and oil quenched tempered spring steel wire are directly around the supply of steel wire spring, spring forming after the elimination of stress directly used.
Most of the production enterprises or large public places, they can play a defense hook mesh in the choice of time, often will hook mesh quality in position, so galvanized hook mesh this product few people are interested in, but does this show that galvanized hook mesh is not useful?
And for the external insulation system is used in the brick veneer, as for the role of first should also be anti fall off followed by anti cracking, so should choose the grid 10×10×0.6, these are some experience choice, grid conversion from the national regulations of steel mesh specifications, using steel level conversion. The index of wire mesh size, wire warp, square meter steel content, galvanized amount, etc., mainly consider the corrosion resistance of wire mesh and the safety of the system! Galvanized wire mesh is more critical than wire diameter, galvanized amount is very important, must be hot plating, welding after plating is better than plating after welding, as for wire diameter, comprehensive consideration of site construction and to meet the needs of safety, 0.6 ~ 0.7 is better.
The form of installation: in the top with the various cage tied together at least as wrapped stone cage net that combination closely not easy to use bad. If the local bandaging is appropriate, it can increase the stability of the structure. There are a lot of grid edge, if the stone cage net only hook in the cage edge and not prepared in the cage edge, even in loose.

3. The transport, storage and use of the binder of galvanized wire mesh should adopt safety and fire prevention methods according to the relevant regulations, so as to be safer.
Attention should be paid to line collection and operation. Others shall not get on the train without the monitor’s consent. The wire reel should be put lightly, stacked firmly and neatly, not more than 5 discs. It is forbidden to contact human skin directly with acid and base. When the acid fog exceeds the specified target of the state, timely measures should be taken to control it; otherwise, production is not allowed.
Hot dip galvanizing is the plating of zinc layer on the surface of Angle steel, channel steel and other metals to achieve the appearance of convenience and rust prevention of metal. Hot-dip zinc processing plants use zinc tin solution to prevent corrosion on the workpiece. This new technology can extend the corrosion time by up to five times, which is usually used in outdoor construction. Because the principle of action is not the same, so the role of the workpiece is not the same. The appearance of hot dip zinc plant is only to expand the scope of action.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
