It’s not clear why friends would want to use building nets for floor heating. What is its advantage in the floor heating project, the role of steel wire mesh is convenient for construction. Building mesh can better fix the pipe, conducive to the construction of the floor, improve efficiency. Anti-cracking function. The building network can improve the bearing capacity of the foundation of the insulation board, the thicker the diameter of the building steel wire, the greater the bearing capacity, effectively prevent the appearance of cracks and cracks of steel wire mesh can improve the thermal shrinkage and shrinkage of cement, strengthen the tensile strength of cement, improve the quality of the heating project.

Because the coating obtained is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In the field of agriculture, such as pesticide irrigation, greenhouse and construction industry such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, it has been widely used in these years.

Generally speaking, there are three kinds of anti-corrosion and anti-rust skills: surface dipping, spraying and surface galvanized, these three ways are to strengthen their anticorrosion ability and resist natural risks, extend their service life. Today we want to talk about the difference between dip plastic hook and galvanized hook.

The silver powder is actually a mixture of aluminum powder and polymer after painting the film, the film is brittle, easy to appear adhesion problems, and corrosion resistance is also slightly poor. Galvanizing refers to the surface of metal, alloy or other materials coated with a layer of zinc to play the role of beautiful, rust prevention and other surface treatment technology. Zinc dissolves easily in acids and also in bases, so it’s an amphoteric metal. Zinc changes little in dry air.

The application range of positive and negative twisting barbed rope is also very wide, is a good choice for purchasing barbed rope, then positive and negative twisting barbed rope compared with other barbed rope advantages? The following Haorong barbed rope factory for you to introduce the positive and negative twisting of the three advantages of barbed rope

We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.

Field fence line net is a streamlined, streamlined, beautiful, tacky, fashionable European elegance; The diversity of color selection, a variety of standard color card colors to choose from, can meet different varieties, different, different needs. On-site fence line can be separated from a variety of methods, and according to the customer’s disagreement request.

There are three methods to detect the thickness of zinc layer of galvanized wire: weighing method, cross section microscopy method and magnetic method, among which the first two experiments will cause certain damage to galvanized wire, including the length of galvanized wire and the reduction of dosage. The general detection of galvanized wire galvanized layer is detected by magnetic method, which is also a more intuitive and convenient method. The standard of galvanized layer thickness is related to the wire diameter of galvanized wire. The larger the wire diameter of galvanized wire, the thicker the galvanized layer is. It is the thickness of galvanized layer and cast iron after centrifugal separation.

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.

Stainless steel barbed rope in the way of corrosion is not very, because the surface is not treated but rely on its own raw materials for corrosion resistance, so there will be no chemical reaction. After a long time of use, it will not rust like the corrosion layer on the surface of hot dip galvanized barbed rope, because the internal material of stainless steel barbed rope is the same as the material on the surface. The most obvious difference in a short time is the cross section of this piece, hot dip galvanized barbed wire because of surface anticorrosion treatment, so there will be rust in the cross section of this piece, and stainless steel barbed wire because the internal raw materials and surface raw materials are consistent, so there is no such situation.

The bonding and anchoring function between cold wire drawing and cold rolled ribbed steel bar and concrete is outstanding. Therefore, when used in components, the phenomenon of cracking of component anchorage area and damage caused by steel wire slip is fundamentally eliminated, and the load-bearing ability and anti-cracking ability of component end are improved. In reinforced concrete structure, the crack width is smaller than that of circular steel bar or even that of hot rolled thread bar.

The first is the cost of raw materials galvanized sheet and galvanized wire, some specifications and waste calculation and so on. Then there is the cost of mechanical processing process and manual processing process. Finally, there is the cost of packing and shipping. In recent years, due to the rapid development of thorn rope manufacturers, so the profit margin of blade thorn rope is not particularly broad.
