Galvanized wire according to the production technology can be divided into: hot galvanized wire, electroplating wire hot plating: 8# — 36# (3.8mm,0.19mm) electroplating: 8# — 38# (3.8mm-0.15mm)
1. The diameter of raw materials and the thickness of the diameter have a direct impact;
In addition, heavy hexagonal net is commonly used in water conservancy projects, as the use of loading stone box, in order to achieve the purpose of river management, floods, in addition to it can also be used as slope prevention, retaining wall, breeding and cherish animals. Small hexagonal net is usually used for animal breeding, wall protection network, green vegetation network and so on.
Spring steel wire with high carbon quality carbon structural steel or carbon tool steel wire rod production, according to the use of spring strict control of its chemical composition, gas content and non-metallic inclusions. In order to reduce the appearance defect and decarbonization layer, the billet of consumption rod should stop the appearance grinding, and if necessary, stop the peeling.
Factors affecting the corrosion resistance of galvanized wire: The corrosion resistance of galvanized wire is affected by many factors, mainly including the following aspects.
If not packaged, then a car of blade thorn rope can not be loaded with many pieces, but also relatively occupied places and easy to be lost in the process of transportation. Each bundle of blade barbed rope is 50 bundles. After hydraulic compression, the volume is reduced and it is more convenient to load and unload. Forklift trucks can load and unload easily. In general, when exporting, the blade thorn rope will be packaged for sale, so that the volume occupied in the container is relatively small, which can be very easy to size and place will not take up much place.
Third, 201 is high manganese content, the surface is very bright with dark bright, high manganese content is easy to rust. 304 contains more chromium, the surface is matte, no rust. Put the two together and you have a comparison. The most important thing is that the corrosion resistance is different. The corrosion resistance of 201 is very poor, so the price will be much cheaper. Because of the low nickel content of 201, the price is lower than 304, so the corrosion resistance is not as good as 304. Steel mesh plastic sprayed: Coating is also we often speak of electrostatic powder spraying coating, it is to make plastic powder charged with static electricity generator, adsorption in the iron plate or other product appearance, and then through 180 ~ 220 ℃ baking, make powder agglomeration adhesion of metal or other objects, plastic product used for indoor use more boxes, paint film present flat or matte effect. Spray powder mainly acrylic powder, polyester powder and so on.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.
Magnetic test method is the original common difference between austenitic stainless steel and ferritic stainless steel simple way, austenitic stainless steel is wrong magnetic steel, but after cold processing under large pressure will have a slight magnetic; But pure chrome steel and low alloy steel are strong magnetic steel.
Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. So why annealing wire according to material properties processing?
Some raw materials in the production of unstable processing, the wire itself will exist burr, surface small pits and other local defects. Galvanized steel in galvanized, generally should pay attention to the galvanized layer protection time of galvanized wire, and the thickness of galvanized layer has a great relationship. Generally speaking, when the main gas is relatively dry and used indoors, the galvanized layer thickness of galvanized wires is only 6-12μm, and under relatively harsh conditions, the galvanized layer thickness of galvanized wires needs 20μm, and can be predicted to reach 50μm.
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
The error of construction welding net diameter should be controlled at 0.02 mm. For example, we buy wire diameter of 89 wire welding net, with a micrometer to measure the diameter, the diameter of the allowable range is 87 -91 wire. In this range is qualified welding net. Because the accuracy has been compared, but no one can control it so well in the production process. The welding net can be accurate to 0.01 mm, so the error is allowed.
Stainless steel blade barbed rope material is produced according to stainless steel plate and stainless steel wire, as a whole have achieved the purpose of high quality anticorrosion. So how long can stainless steel blade thorn rope be used?
Hot – plated wire average performance: reflected in its cross – section, longitudinal uniformity. In the actual process of operation, such as steel wire jitter, the surface scum plating pot and other reasons will cause the surface of galvanized wire galvanized layer accumulation, should strive to solve the problem. In addition to these reasons, we should pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of the galvanized layer.
3. Acid activation acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts, without excessive corrosion on the matrix.
Greenhouse special electroplating process iron wire blackening solution:
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, which is characterized by beautiful, lightweight, folding, easy to store. The surface treatment of pet cage is generally: cold galvanized, hot galvanized, spray, dip, chromium plating, nickel plating and other methods.
