The welding process of galvanized steel wire mesh because of low carbon steel carbon content is low, manganese and silicon content is low, will not occur severe hardening or quenching structure due to welding. The low carbon steel joints have excellent plasticity and impact toughness after welding. In the welding process, it is generally not necessary to preheat, interlayer temperature control, post-heating control and heat treatment to improve the welding structure.
Hot dip galvanized hexagonal net is made of low carbon steel wire by mechanized braided welding and then by hot dip zinc treatment. The net color is white and shiny, thick zinc layer, uniform mesh, flat mesh surface, solder joint tension resistance, high corrosion resistance. The surface of the steel wire is usually protected by hot-dip galvanizing, and the thickness of the galvanized protective layer can be made according to the requirements of customers. Hot-dip galvanizing hexagonal net is another kind of twisting mesh corresponding to the galvanizing hexagonal net.
Pet cages can be used for indoor and outdoor pet houses. The dog cage is equipped with a fixed food basin and a drinking device, and the rubber pad of the pet cage with a bayonet on the four sides can be assembled. Can be splicing according to the size of the cage, shear, disassembly convenient, easy to clean, can solve the puppy in the ordinary cage pinched foot problem, prevent the puppy in the development of adverse reactions. The bulkhead of the pet cage is breathable and comfortable, which can be used as a heat shield for pets in summer. A puppy with small feet, not a foot, not a pinch.
Hot drawing is the heating before the wire enters the die hole, mainly used for high melting point wire drawing; The temperature drawing is carried out by heating the heater to the range of temperature, mainly used for galvanized steel wire, difficult to deform drawing.
Take 20cm galvanized wire for acid fog experiment, check the zinc content of galvanized wire through the balance to see whether it meets the zinc layer standard required by customers, ensure that the metal wire achieves the role of rust and corrosion prevention, and meet the service life required by customers. Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound inward to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test, which is decided according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.
Hook mesh is crocheted with silk heart, its mesh is uniform, flat net surface, beautiful and generous net width, thick silk diameter, not easy to corroded long life, weaving simple, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Protection of mechanical equipment, highway guardrail, sports site fence, road beautification with protective net. The screen in the manufacture of a box-like container, with stone filled with the cage, can be used to maintain and support seawall, hillside, road and bridge, reservoir and other civil engineering.
Pay attention to the maintenance of the dog cage, plastic and wire and other materials of the dog cage need to avoid exposure to the sun, the dog cage must be cleaned in time after cleaning with water, or rust will affect the service life.Barbed wire production of general selection of low carbon iron wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong consolidation, even if part of the trade-off or under pressure will not appear lax phenomenon.
The quality of hot-dip galvanized barbed wire is only in the surface of the wire attached to the galvanized layer, and with the reason of the chemical reaction, the surface of the zinc layer will gradually lose its role because of the oxidation reaction, this situation is more prominent in humid areas. And because after all, the steel wire will rust, so the quality of hot-dip galvanized barbed wire is certainly not up to the level of stainless steel barbed wire.
In current market is a lot of manufacturers, that is to say, when consumer is choosing the blade thorn rope can see more manufacturers, after the contrast is that you can know what is good, can from the strength of the manufacturer, the type of product, the quality of the product and the price of the maternity leave and so on comprehensive comparison, so when the actual choice will be more easy and convenient, And the high-value blade barbed rope in the use process can also play better, so that we really know what is a good product.Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
Using activated carbon mat to remove surface active substances, or through filtration to make the foam is not too stable, this is an effective measure; Other measures should also be taken to reduce the amount of surfactant introduced to Z.
The entire steel surface is protected, and the melted zinc is easily coated evenly, whether in the interior of the pipe fitting in a depression, or in any other corner where the coating is difficult to access. The hardness of galvanized coating is greater than that of steel. The Eta layer of the upper layer of Z is only 70 DPN hardness, so it is easy to be dented by collisions. However, the hardness values of the lower layer of Zeta layer and delta layer are 179 and 211 DPN respectively, which are higher than that of the iron material of 159 DPN. Therefore, its impact resistance and wear resistance are quite good.
With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.
