Large roll galvanized wire can be divided into hot-dip galvanized wire and cold galvanized wire, the difference between the two lies in the way of zinc and the amount of zinc. Hot dip galvanizing is to soak steel wire in melted zinc liquid, hot dip galvanizing zinc fast, zinc layer thick rust prevention performance is very good, but the zinc is not uniform, and the surface is dark, the life of hot dip galvanizing can reach 20 years.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering mesh, mesh should be less than 20 and diameter greater than 1 nm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering mesh. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.
Environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire. Galvanized methods are mainly divided into two types, one is hot dip galvanizing method, the other is electric galvanizing method. This paper mainly introduces the method of galvanizing. Electrogalvanizing is an electrolyte used for galvanizing.
When using these two products, it is obvious that there is a gap between them. By pulling or bending the wire, it is often difficult to restore the original, for example, if the same place is repeatedly bent, it will be found that it has broken, and the cold drawing wire will not. Cold drawing wire compared with iron wire, its hardness, tensile resistance, bending ability is greatly enhanced, suitable for building materials.
In GENERAL, THE HARDNESS OF A METAL IS OFTEN CONSIDERED AS THE RESISTANCE OF a MATERIAL TO COMPRESSION PLASTIC deformation, scratches, wear, or cutting. In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, according to the time of zinc dip, wire diameter, and then estimate the zinc dip distance. By adjusting the zinc dipping distance, the zinc dipping time of various specifications of steel wire is shortened by 5s on average compared with that before debugging, so that the zinc consumption is reduced, the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg.
1, no paint and maintenance, long new not old, exempt you from maintenance fatigue and trouble, the lowest comprehensive cost. Stainless steel wire mesh can be used as poultry cage, egg basket, channel fence, drain tank, porch guardrail, anti rat net, mechanical protective cover, livestock and plant fence, grid frame, etc.
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.
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.
Galvanized electric welding mesh refers to the mesh made of zinc alloy material, because of its high strength, high hardness, beautiful appearance, bright color and other advantages, become used in residential communities. Traditional electric welding mesh using iron bars, aluminum alloy materials, need to use welding and other technology, and the texture is soft, easy to rust, single color.
For the specification of galvanized wire, the galvanized wire produced by our factory can range from No.8 to No.22, which refers to the BWG standard, that is, from about 4mm to 0.7mm, which can basically cover the type required by the customer. As for the raw material of galvanized wire, normally, we use Q195 mild steel, and some factories will also use SAE1006 or SAE1008. The following is the zinc coating, for galvanized wire, this is very important, the general zinc coating is about 50g/m2 to 80g/m2, some customers need high zinc galvanized wire, zinc coating can reach 200g/m2 to 360g/m2. The tensile strength of galvanized wire is usually 350n/m2 to 800n/m2. Then there is the packaging specification of galvanized wire. The specifications of small rolls of galvanized wire are 50kg/ roll, 100kg/ roll and 200kg/ roll. Of course, there are large rolls of galvanized wire, the weight can reach 300kg/ roll or 800kg/ roll.
Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.
Bird cage is a kind of pet cage, is the main environment for ornamental birds to carry out activities and habitat, “work to do a good job, must first sharpen its tools” bird equipment is applicable or not, is one of the key to raise ornamental birds. Therefore, only if the appropriate cage and other accessories are prepared first, can the birds be kept healthy and lively, singing freely and suitable for viewing. There are many kinds of cages, depending on their body shape and habits.
