Common galvanized iron wire equipment is usually used in barbecue net, barbecue net generally requires to have a long service life, with galvanized iron wire equipment to wire a layer of zinc, barbecue net is not easy to be corroded.
As we all know, iron wire rust is due to contact with water and oxygen chemical reaction, therefore, how to prevent galvanized iron wire rust, first of all, in the storage of galvanized iron wire should choose ventilated dry place, avoid wet or rain leakage, in use, in addition to follow the principle of first in first out, if accidentally caused by the destruction of galvanized layer, should be coated with anti-rust paint treatment, Otherwise, it is easy to lose the protection of galvanized layer and cause galvanized iron wire rust.
In order to pack and bundle galvanized wire on the surface of the deposit layer to remove the surface film, surface inclusion and other defects can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. Small homogeneous particles of large denier present in the tank can stabilize the foam layer. 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 intake of surfactant. 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.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Aquaculture galvanized welding net this mesh structure is easy to construction, to ensure quality. Compared with the traditional manual binding on site, it can guarantee the quality of the project, shorten the anti-drug construction and shorten the construction period. So now such grids are being used in new villages to strengthen walls and prevent earthquakes.
The construction of inner wall and outer wall steel wire mesh can effectively solve the wall cracks, falling off, empty drum phenomenon. Hot dip galvanized steel wire mesh material requirements: net surface leveling, width and length to meet the project required standards, welding process, weight, zinc, etc., with more production and operation, detection certificate is complete.
The wire diameter of raw materials used in different types of barbed rope is also very different, but in the production and processing process of barbed rope need to know the amount of use.
3, barbed rope protection net in the bridge, channel, should be toward the bridge head cone slope (or end wall) direction surrounded, should not leave for people, livestock can drill into the gap.There are many categories of large rolls of galvanized wire, and different categories can be applied to different scenarios. The common application of galvanized iron wire is the application of the construction industry. One is the use of binding wire. Whether it is the binding of scaffolding or reinforcement, galvanized iron wire is needed to carry out. There are also 20kg or 50kg bundles of No. 18, No. 16, No. 14, No. 12, No. 10 galvanized coils.
The installation of guardrail should also follow certain steps, first of all, after the guardrail is transported, according to the length of the guardrail, determine the distance between the column, if the installation of the guardrail field is soft ground, then you can first dig out a 40*40*50cm embedded machine base. If it is a concrete floor, as long as the expansion bolt directly fixed. 2. To avoid galvanized iron wire being gripped by tools like pliers or hardened claws, when the wire suffers from tension or bending stress, scoring or pooping on the surface can lead to damage.Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
Fourth, the difference between 201 and 304 is the problem of nickel. And the price of 304 is relatively expensive now, generally close to 20,000 yuan per ton, but 304 can at least ensure that it will not rust in the process of use. (Experiment with potions)
Low and medium carbon steel wire is used as raw material, with good surface gloss, uniform zinc layer, strong adhesion, corrosion resistance and so on. Available: diameter 1.60mm-4mm (16#-33#) cold plating wire; Diameter 6.40mm-0.81mm(8#-21#) black iron wire, changed wire. It is mainly used in communication equipment, medical equipment, weaving net, brush, steel cable, filter, high-pressure pipe, construction, crafts and other industries.
The strength of the hook mesh should be satisfied: when the vehicle is traveling at 80 kilometers per hour, the hook mesh will not fall into the river when it bumps against the rail at a 15 degree Angle. The shape and color of the hook mesh should be in harmony with the surrounding natural environment. The phenomenon planning of the important Bridges should be done well. When the bridge crosses important traffic lines, such as expressways, urban rail transit, expressways, railway trunk lines, etc., the hook mesh should add the protective mesh on the pavement of the bridge deck.
Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.
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.
Enclosure to calculate the use of barbed rope, so as to reasonably plan to purchase the amount of barbed rope to facilitate construction
Electric welding net is also known as external wall insulation wire mesh, galvanized wire, galvanized electric welding net, wire mesh, row welding net, touch welding net, construction net, external wall insulation net, decorative net, wire mesh, square eye mesh, screen mesh, anti-crack mesh. Stainless steel electric welding mesh, is made of high quality stainless steel wire row welding, more acid resistance, alkali resistance, welding firm, beautiful, widely used and so on.
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.
Nemesis roller cage is used for the isolation and protection of pasture distance, railway and highway, as well as the enclosure and protection of garden apartment, government units, guard posts and border defense. The Nestor rolling cage is fixed with Nestor connecting card at intervals of 120° after the blade barbed rope is wound around the cage. After opening, the Nestor connecting card is formed into a snake belly network. After closing, the diameter of the blade barbed rope ring is 50cm.
