Each coil of steel wire shall consist of one wire. The surface of the rod shall not have cracks, folds, scars, ears, layers or inclusions. However, indentation, pits, bumps, scratches and pockmarks are allowed, and the depth or height shall not be 0.2mm. There should be no corrosion and oxidation skin on the surface of the steel wire, and oxidation color is allowed by heat treatment. The surface of the wire is allowed to have scratches not exceeding half of the allowable deviation range of the diameter, and local defects not exceeding the allowable deviation of the appropriate diameter.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
Hexagonal mesh is a metal wire woven Angle mesh (hexagonal) made of wire mesh, the use of metal wire diameter is based on the size of the hexagonal and different. If it is a hexagonal metal galvanized layer of metal wire, the wire diameter is 0.3mm to 2.0mm metal wire, if it is a PVC coated metal wire braided hexagonal net, the use of 0.8mm to 2.6mm PVC(metal) wire. Twisted into a hexagonal shape, the outer frame edge of the line can be made into a unilateral, bilateral, movable silk. 3. The structure of the dog cage should be reasonable
Large coil galvanized wire in the zinc immersion distance debugging, keep the original speed unchanged, according to t= KD to determine the zinc immersion time (1), where: t is the zinc immersion time is constant, take 4-7D is the diameter of steel wire mm, and then estimate the zinc immersion distance. By adjusting the zinc dip distance, the zinc dip time of steel wire of various specifications can be shortened by 5s on average. In this way, the zinc consumption per ton of steel wire decreases from 61kg to 59.4kg.
Now it is more used in the binding of the construction industry. Compared with ordinary wire, it is also softer and has better luster. Use in daily life does not need to carry out maintenance and maintenance, saving a lot of time, but also save the cost of maintenance and maintenance. Annealed wire has good stability, good corrosion resistance, greatly prolonging the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved. The material properties of annealed wire can meet different processing needs.
Greenhouse special electroplating process iron wire blackening solution:
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed rope has beautiful, economical and practical, good resistance effect, convenient construction and other excellent characteristics.
Different from double strands of barbed wire to install directly on the ground, the blade thorn rope is fixed on some affiliate products just again, as was the case according to the common on the wall, often wall width is far lower than the diameter of the blade thorn rope under the premise of no such device is fixed in place, use special stents to prevent blade thorn rope can better protect us.
Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.
Two, the production process is different
When the barbed rope is used, it is calculated according to the length, while when purchasing the barbed rope, it is calculated according to the weight of the barbed rope, which causes the confusion of users’ difficulty in counting the quantity of purchase. Therefore, it is necessary to understand clearly that there are less meters per kilogram of the barbed rope. How much does a barbed rope weigh in a meter? These two problems, the purchase of barbed rope becomes very simple.
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.
Coping methods we also have: 1, gouging, the straight wire rolled into a wavy shape, but still not enough to raise chickens with mesh can only be large enough to extend the beak can not feed! 2, is the electric welding net, with the current to wire spot welding together, mesh is not limited.
There is no need to carry out daily maintenance and maintenance when in use, which can not only save a lot of time, but also reduce the cost, but also has good stability, strong corrosion resistance, greatly extend the service life. According to the different technology is divided into different types, can be selected according to their own needs, has better flexibility and elasticity. The main function of annealing wire is to control its hardness, when the annealing wire is made of steel wire.
