The main difference is carbon content. Iron has a carbon content of 2.11 percent or more, while steel has a carbon content of 2.11 percent or less. Iron-carbon alloys with carbon content of more than 2.11% are cast iron (pig iron), which are basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different, and the content of harmful impurities such as sulfur and phosphorus in steel is smaller. Wire general color key, wire color light point, white point.
And the role of wire mesh in the exterior wall plastering if from an Angle to sail a method of anti-falling, the role of anti-cracking is relatively small, because of the problem of orientation; And about the external insulation system is used in the tile veneer, as for the role should also be anti-drop followed by anti-cracking, so the grid should be selected 10×10×0.6, these are some experience selection, grid conversion from the national provisions of the wire mesh standard, choose the level of steel conversion.
As we all know, the mechanism of resistance to atmospheric corrosion of zinc includes mechanical protection and electrochemical protection. Under the condition of atmospheric corrosion, there are ZnO, Zn(OH)2 and basic zinc carbonate protective film on the surface of zinc layer, which to a certain extent slows the corrosion of zinc. When this protective film (also known as white rust) is damaged, a new film will be formed.
Traditional wire mesh is crisscross woven into the wire, with the development of the economy, the rapid rise of all walks of life, the use of traditional wire mesh limitations gradually exposed, such as: aquaculture, to the chicken circle a cage can not be too dense, the wire can not be too thick, woven up the net wire once the mesh is too large net surface will become soft.
From the point of view of spray, spray blade gill net (PVC blade gill net, coated blade gill net) is also called spray blade barbed wire, spray blade barbed wire is the blade barbed wire produced in the future, to carry out anti-rust treatment. Spray surface treatment to make it has quite good anti-corrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical outstanding characteristics. Plastic sprayed blade barbed rope is a surface treatment method of spraying plastic powder on blade barbed rope in process.
Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid resistant steel. And galvanized wire has good toughness and elasticity, the amount of 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 mesh, highway fence, product packaging and daily civilian and other fields.
Products are widely used in construction, handicrafts, wire mesh, highway guardrail, product packaging and daily civilian and other fields. Galvanized wire is divided into hot galvanizing, cold galvanizing, electric galvanizing, hot galvanizing price is high, the price of electric galvanizing is low. Hot dip galvanizing is not easy to rust, electric galvanizing is easy to rust, this is a simple discrimination. Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns.
On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.
Steel mesh manual binding line of the joint simple sliding, steel and concrete strength is weak, simple crack. The welded joint can accept not only pressure but also shear force. Longitudinal and transverse steel bars form a network structure, which plays a bonding anchorage effect. The number of solder joints per unit area is added when the diameter of the wire mesh is small and closely spaced. More conducive to strengthening the crack resistance of concrete, can reduce more than 75 percent of the attack of steel mesh cracks is a new, energy-efficient steel mesh structure, used in beams and columns, floors, roofs, walls, concrete pavement, bridge deck paving and other industrial and civil buildings.
Pet cage has many types, and selective is bigger, pet cages are generally made of wire, with better coarse, then at the bottom with a wheel base, such a simple pet basket was made, in the wheel at the bottom of the mount is for the convenience of the mobile, a pet cages should also adapt to the location of the production in addition to a door, It is convenient for feeding pets.
In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.
