In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.
Because of the large size of the barbed rope, the rope factory is used to packing. If you do not pack, then a load of blade rope can not hold many pieces, but also relatively occupy space and easy to be lost in the process of transportation.
The policy of wire mesh mesh size, wire, square meter steel content, galvanized amount, etc., to consider the corrosion resistance of wire mesh ability and system safety! Wire mesh galvanized is more fierce than wire diameter, galvanized amount is very important, must be hot plating, welding after plating is better than the first plating after welding, as for wire diameter, summed up to consider the site construction and meet the needs of safety.To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
The quantity should be the same as the contract, cold drawing, carefully record the quantity of each specification and packing method. If there is a label, check whether the label is correct and take a photo to confirm. Each roll of iron wire is fastened with galvanized packing tape, and then tied with a very strong transparent plastic bag. The coated iron wire is wrapped with white braided cloth, and the galvanized iron wire is wrapped with green braided cloth, so as to ensure that the packaging will not be lax in the transportation process.
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.
The duration of the protective effect of galvanized layer on large roll galvanized wire is closely related to the coating thickness. Generally speaking, in the dry main gas and indoor use, the thickness of galvanized layer only 6-12μm, and in the environment is more severe conditions, galvanized layer thickness needs 20μm “to be up to 50μm”. Therefore, the influence of environment should be considered when choosing the thickness of galvanized layer.
The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).
The formation process of hot dip galvanized layer is the process of forming iron-zinc alloy between the iron matrix and the outside pure zinc layer. The surface of the workpiece forms the iron-zinc alloy layer during the hot dip plating, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc solution, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the gravitational attraction between the atoms is relatively small.
Now many industrial products will be made of stainless steel wire rope material. In order to identify the fake and inferior stainless steel, certain measures and methods can be taken. But many customers do not know what way to identify, listed the following identification methods for you.
