nails that go into concrete

With the improvement of people’s living standards, now many families are raising some small pets, these small pets also need a safe nest, pet cage has become an important choice of people, each pet’s habits and living habits will choose to adapt to the cage.

In use, it can be well used to control the degree of softness and hardness in the annealing process, mainly used for binding silk and binding wire in the construction industry. Its use is not limited to handicrafts, of course, in the construction industry is also widely used. In the early days, the lanterns were made with wire outside and proper candles were placed inside. People hung them in front of the door and it was very beautiful to go up at night.

First, the effect of tensile strength or hardness of steel wire

Bridge reinforcement reason is the bridge durability function is poor and aging, through the steel wire mesh reinforcement, can prolong the service life of the bridge, avoid the bridge cracks, collapse and other phenomena, steel wire mesh in bridge reinforcement anti-crack engineering can play an obvious effect, improve the construction speed of the project, enhance the concrete anti-crack function, induction of good economic benefits.

The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.

Blade barbed rope production links need to be many times before the finished product, roughly down to four or five links.

Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.

Hot dip galvanizing, also known as hot dip galvanizing, is a method of obtaining a metal covering layer by immersing a steel member into a molten zinc solution. With the rapid development of high-voltage power transmission, transportation and communication, the protection requirements for steel parts are becoming higher and higher, and the demand for hot-dip galvanizing is also increasing. Usually the thickness of electrogalvanized layer is 5 ~ 15μm, and the large roll galvanized wire layer is generally more than 35μm, or even up to 200μm. Hot dip galvanized coating ability is good, dense coating, no organic inclusions.

Blade thorn rope because the volume is relatively large, so the thorn rope factory is used to packaging treatment.

Generally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.

The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.

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.

Galvanized wire coating rough, passivation film is not bright, bath temperature is too high. If the cathode current density is too high, zinc content in the bath is too high or sodium hydroxide and DPE content is too low; Electroplating solution with solid particles or excessive foreign metal impurities, will lead to such problems. Solution: If the large roll galvanized wire to the above coating is rough, there may be solid particles in the plating solution. If the roughness of the part is severe, the current density may be too high.

When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

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:

The development of iron wire industry in our country is still very good, among which there is a kind of iron wire called large roll galvanized wire, which is also widely used with its own good performance. In fact, the zinc layer plays a protective effect on the iron wire inside, which can ensure that the iron wire is not oxidized, and it is convenient and beautiful to use. Galvanized iron wire is formed by pickling, high temperature, hot dip galvanizing and other steps. It has good toughness and elasticity and can be applied to many civil fields.
