Greenhouse special electroplating process iron wire blackening solution:
- Barbed rope manufacturers specializing in galvanized barbed rope, hot dip galvanized barbed rope, blade barbed rope, stainless steel barbed rope, plastic coated barbed rope, positive and negative twisted barbed rope production for ten years.
- Packing and binding galvanized wire is in the liquid state of zinc, after a messy physical and chemical effect, not only on the steel plated thick pure zinc layer, and also generate a zinc-iron alloy layer. This plating method, not only has the characteristics of corrosion resistance of galvanized wire, and because of the zinc iron alloy layer. It also has strong corrosion resistance that can not be compared with electric galvanizing. Therefore, this plating method is particularly suitable for a variety of strong acid, alkali fog and other strong corrosive environment.
- (2) Spray large number hook mesh guardrail should be used electric spray paint or electrostatic spray paint.
As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:
- 1, the width and length of the hexagonal net (according to your actual needs, the width and length we can adjust flexibly).
- 2, line diameter, mesh spacing (refers to the edge of the twist to the opposite side of the distance).
Stainless steel hexagonal network is composed of machine will be produced stainless steel wire of a kind of metal mesh, not easy corrosion, the survival of the fixed number of year is longer, net of wide, coarser size, strong practicability, flexibility and other unique places, stainless steel hexagonal wire netting material is stainless steel wire, wire diameter because stainless steel wire big viscosity of large stainless steel hexagonal network would be hard to manufacture, Of course, it is more difficult to hold the edge or twist the edge, so stainless steel hexagonal mesh whether from the material or artificial are expensive, but stainless steel hexagonal mesh will not rust and use years is also very long, appearance without disposal can achieve the use effect.
When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.
- With a large pickpocket for the steel wire, into the zinc liquid before the surface of the zinc ash stirring; Use a small outlet for steel wire galvanized; Zinc pot steel wire outlet in 30 minutes, with the pickpocket back and forth, until the large, floating zinc residue into brown yellow, real zinc ash, zinc ash surface. The zinc ash taken out should be brown yellow real zinc ash, zinc surface, effectively reduce the zinc consumption. This is one of the biggest measures to reduce zinc consumption, and it is a real problem, which has not been solved for many years.
- (7) twist twist hexagonal mesh is made to use low carbon steel wire galvanized large wire braided, the tensile strength of steel wire is not less than 38kg/㎡, the diameter of steel wire up to 2.0mm-3.2mm, the surface of steel wire is usually hot galvanized protection, galvanized protective layer thickness can be made according to customer requirements, galvanized amount can reach 300g/㎡.
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.
Thorn rope factory can not only have one type of product when processing thorn rope, a variety of models can meet the protection needs of different customers.
Wire mesh production of general selection of low carbon 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 and consolidated, even if part of the choice or pressure will not appear lax phenomenon.
The wire rod should be normalized or soxhlet processed, instead of spheroidal annealing for standard large ones. Soxhlet process is widely used in the heat treatment of the center, especially the products before drawing. Avoid decarbonization during heat treatment. After heat treatment, sulfuric acid or hydrochloric acid pickling is used to remove iron sheet. The coating (see smooth carrier) can be dip-lime, phosphating, borax treatment or copper plating.
The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.
According to the different requirements of the industry, different weights of alloy ingots are put in the smelting furnace according to the standard, such as weaving, Ming, paper, lang, silicon, etc., and the data out of this smelting is called gold ore iron. Iron has gray iron, white iron and the above-mentioned gold, they have different characteristics, so in the industry according to their different characteristics to transport and selection. For example, in gray iron, its carbon exists in iron ore in graphite condition, the crack is often gray, soft and strong, simple filtering, suitable for casting.
The iron wire used for the barbed wire is woven or welded into low carbon steel wire, medium carbon steel wire, high carbon steel wire, stainless steel wire and other materials. Production process: general braided, embossed braided and spot welding. If the material is steel wire, after equipment processing into a network, it is called wire mesh.
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, the use of low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can be cut off the tie wire used in the building, the length of 20cm 30cm 40cm, can be cut off according to requirements.
Hexagonal net structure can be used for slope support, excavation, rock face net mine support form, slope vegetation (green color), railway road isolation block, it can be made into a cage, pad, used for river, flood dam and seawall erosion protection and reservoir, river closed cage. Driving and guiding rivers and waterlogging disasters are major water erosion damage to rivers, resulting in flooding, resulting in significant loss of property and loss of water and soil. Because of this, in dealing with these problems, the application of the living grid structure becomes a solution plan, which makes it possible to protect the shore forever.
- The drawing process of the waste product has a great influence on the function of the product. The general selection of about 90% of the larger total surface reduction rate (see area reduction rate) and the smaller pass surface reduction rate (about 23%), to ensure the endurance of the product. On the high strength spring steel wire, pulling should be controlled each time the temperature of the steel wire outlet is lower than 150℃, to prevent the steel wire due to strain aging and change the crack, which is the main drawback of steel wire waste.
The main factors causing metal rust: relative humidity of the atmosphere at the same temperature, the percentage of water vapor content and water vapor saturation content in the atmosphere, known as relative humidity. Under certain relative humidity, the corrosion rate of metal antirust oil is very small, but higher than the relative humidity, the corrosion rate increases suddenly. This relative humidity is called the critical humidity. When the humidity in the atmosphere is higher than the critical humidity, the metal surface will appear water film or water droplets, if the atmosphere contains harmful impurities, dissolved in the water film, water droplets, electrolytes and aggravate corrosion.
