- First of all, we need to understand that the electrical conductivity of the wire depends on its material and size, and is not affected by the surface treatment method. Whether galvanized treatment or wire drawing treatment, they are the surface of the steel wire treatment, will not change the basic physical properties of the steel wire, electrical conductivity will not be affected. Therefore, in theory, the galvanized wire drawing treatment should not have any effect on the electrical conductivity of the steel wire.

Post time: 23-11-22Like highway guardrail, silk screen can be used, in production can also be according to the needs of customers, such as the need for different diameters of galvanized wire products, in the material selection and coating to carry out reasonable control. Our industry is a low carbon steel with good quality as raw material, and then through the pulling out, galvanized process, thus producing good galvanized iron wire.
Post time: 06-01-23- Hook mesh from the point of view of weaving quality inspection requirements, hook mesh wire and silk staggered can not loose, the whole piece of hook mesh can not loose deformation. Of course, if the customer special requirements out of the net, showing loose phenomenon can not blame the production side. Whether the mesh meets the specification requirements and the wire diameter meets the wire diameter.
The hot plating wire uses zinc-free slag to add hot melt zinc and galvanize, which avoids the traditional heating process and radiates the surface 1653 of zinc liquid surface 4102 to the hot melt zinc, reducing the high temperature oxidation on the surface of zinc liquid. At the same time, the heating body is in contact with the zinc liquid, and the heat is directly transferred to the zinc liquid. The utilization rate of heat energy can reach more than 90%, which reduces the heat radiation of the zinc liquid surface.
The application of electric welding net is more widely, at present it has replaced the use of other parts of the wire mesh, the cost of electric welding net is lower, the production speed is very fast, so it is very popular. Welding net galvanized before the need for processing is recrystallization annealing, because the welding net must maintain a no oxide and no other impurities of pure iron active surface, if you can not keep its surface clean will lead to a bad galvanizing effect, galvanized layer and iron material is not closely combined, so this step is necessary.
The production process of stainless steel blade piercing rope is basically similar to that of galvanized blade piercing rope, and the blade size is usually determined according to the mold.
- The acceptance of cold-drawn low carbon steel wire shall be conducted according to the same production unit, the same raw material, the same diameter, and shall not exceed 30T for an inspection lot, and check the base material into the factory or out of the inspection statement. The inspection items for each inspection lot are appearance quality, diameter error, tensile test (including tensile strength and elongation) and repeated bending test.
A variety of arc, undivided Angle and undivided elevation ladder mounts are available to provide the ideal treatment plan. It can be used together with the appearance and the design of the common trackless active shift door, forming a harmonious and intact whole.
Two, the production process is different
Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.
In our daily life, what we can bend with our hands is basically galvanized iron wire, not steel wire. It has a high zinc content, which ensures excellent toughness and resilience, as well as ultra-high corrosion resistance, which can be maintained in outdoor environments for decades. There are many practical galvanized iron wire, such as strong reliability, galvanized layer and iron together, forming a special metallurgical structure, in the use and transportation process, can ensure that it will not be mechanical damage.
Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.
Cold wire drawing is mainly used in the production of hardened low carbon steel wire, with a diameter of 8 mm steel bar to play a fixed role in the development of the construction industry has played a role in promoting the development of the construction industry, widely used. The bonding and anchorage performance between cold wire drawing and concrete is good. When used in components, the phenomenon of cracking in the anchorage area of components and damage caused by steel wire slip is fundamentally eliminated, and the bearing capacity and anti-cracking capacity of the end of components are improved.
In order to make the zinc content of steel wire stable in the future, and maintain its uniformity, as far as possible to reduce the zinc content, and effectively reduce zinc consumption to the actual work, the following measures are proposed by the wire factory:
Post time: 14-12-22
Post time: 29-12-22- Zinc pot workers should be determined to do duty and responsibility. Do not leave the post without leave, always observe the change of hot plating wire galvanized layer, and according to the analysis results, master the asbestos block gap friction, how long it takes to press, replace the pressing face; Adjust the working face; Until all four faces of the asbestos block are used up, maintenance workers can continue to use the asbestos block after repair when necessary to reduce the consumption of asbestos block.
- The diameter of welded mesh wire for external walls is generally 2.2-ф4.0, and the mesh is generally 25-50.
Ordinary installation of blade thorn rope on the wall and the height of the wall in two meters up and down the general construction costs in a dozen yuan a meter, but if it is said that the height of the prison construction ordinary wall has reached four or five meters so that the construction cost of each meter is about 30 or 40 yuan, mainly because of high altitude operation risk degree is relatively large reason. The construction cost is different, but the price of blade thorn rope is the same, often the construction cost is higher than the product, which is the thorn rope factory recommends customers to use better quality blade thorn rope, which eliminates the cumbersome time and cost of subsequent demolition and installation.
Cold wire drawing is a kind of cold processing of metal, that is, we often say reinforcement. Cold drawing process is not messy, cold drawing price based on the quality of cold drawing dividends of different levels, cold drawing production is also a variety of different procedures. The main factor affecting the strength of cold drawing wire is raw materials, which are closely related to the raw materials, strength and diameter of raw materials, and the better the quality of cold drawing wire, the more messy the production process.
Post time: 23-05-22- Three: packaging: moisture-proof paper, woven bag strip, other packaging can be packed according to customer requirements
When the pet consignments need to use a special pet cage, usually domestic pet cage are not qualified. Prior to shipment, the pet must be taken to the airport for quarantine inspection. The quarantine certificate should be attached to the waybill. After confirming your flight, arrive at the airport at least 3 hours in advance, anticipate the waiting time and flight time, prepare enough water and food for pets, hot weather, poor ventilation, etc., will cause harm to pets. Those who want to take pets with public transport, must go to the animal quarantine station, with proof of immunity for the county animal quarantine certificate. Clean and disinfect the pet carrier.
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.
As a very important product of the barbed rope factory blade barbed rope can be said to have made a great contribution, but often due to the opaque processing process often do not get the trust of customers.
Post time: 04-04-23- Relatively speaking, the wire is relatively soft, suitable for binding. Disadvantages are low hardness, low tension, easy to stretch, not suitable for building materials. In different applicable environment, we should make a reasonable choice. So in the usual use of cold drawing wire and wire, according to their own needs to choose, although the length of the same, but the performance is not the same.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
Galvanized wire mesh is divided into hot dip galvanized wire mesh and cold galvanized wire mesh. Galvanized steel wire net selects the high quality low carbon steel wire, iron wire factory made by precision of automation machinery welding technology processing, smooth surface, firm structure, integrity is strong, even if the local cutting of galvanized steel wire net, or local also under pressure from loose phenomenon, after molding, wire mesh galvanized corrosion resistance good, has the advantage that the general steel mesh does not have.
Hook mesh we usually see everywhere, in fact, hook mesh is a kind of fence, like the highway, stadium fence, road fence, etc., have hook mesh. So what are the effects and advantages of the use of hook net?
There are two main points to choose the blade to stab the rope
