Cold plating is a physical treatment method, the zinc is simple and uneven, the amount of zinc is also less than in the corrosion and rust prevention and chemical disposal of hot plating; The amount of hot zinc plating is relatively thick, the surface of the disposal is flat on average, and it is not easy to fall off. A layer of alloy composed of zinc and metal has very strong oxidation ability, and there is a layer of pure zinc on the outside of this layer of alloy, which is why hot plating is thicker and stronger than cold plating. Under the condition of high degree of natural recovery, galvanized hook net can play a very good maintenance effect on the environment, it is not afraid of wind and rain, it is the battle machine in the hook net, much stronger than the dip plastic hook net.
Electro galvanizing shaft wire direct is in the electroplating tank through the current unidirectional zinc gradually plated on the metal surface, production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, electric galvanizing has lower production cost. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanized shiny hair white.
1. The diameter of raw materials and the thickness of the diameter have a direct impact;
- If adult dogs and puppies touch noses out of love for the dog, then adult dog nose touch is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
- 3, PVC plastic coated barbed rope protection function is very good
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
- 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.
Steel mesh galvanized: galvanized refers to the surface of metal, alloy or other materials coated with a layer of zinc to play a beautiful, rust prevention and other surface disposal technology. Now the first choice of method is hot dip galvanized, galvanized solution has cyanide bath and cyanide-free bath two categories. Cyanide bath bisects micro cyanide, low cyanide, medium cyanide, and high cyanide.
Post time: 31-10-22Flexibility because the wire is different from other stainless steel raw materials, it is low density so in the flexibility of the appropriate excellent, it can be described according to people’s fantasy into all kinds of different shapes. Some large enterprises will buy hook flower net products, its reasons are no more than two, one is to prevent people outside the enterprise to walk around at will, the second is to advance the whole image of the enterprise. Therefore, under the premise that the protection requirements are not high, galvanized hook net can play a role in its use, the appearance of flexible hook net is settled to the use of address, from a distance and look at it like a work of art quite appreciate the meaning.
If the blade barbed rope produced by the barbed rope factory wants to be made into a straight line, it can’t be made too long because of the constraints of logistics.
- Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and rust prevention. The main method used now is hot galvanizing. However, hot dip galvanizing industry has been developed with the rapid development of cold strip rolling in the past 30 years. The production process of hot-galvanized sheet mainly includes: raw plate preparation → pre-plating treatment → hot-dip plating → post-plating treatment → finished product inspection and so on.
2. Adjust the drawing process parameters of the water tank
- Large hexagonal net called stone cage net, mainly used for mountain preparedness protection, hydraulic construction, etc. Small wire hexagonal net is used as a good material for culture, will twist the hexagonal net in the welding of the iron frame on the hexagonal net welding into chicken cage, pigeon cage, rabbit cage and other cage, hexagonal net is an excellent material for culture with net.
Post time: 27-04-22- There are many kinds of zinc plating solution, which can be divided into plating solution and no plating solution according to its properties. The galvanized liquid has good dispersion and covering property, the coating crystal is smooth and fine, the operation is simple, the application range is wide, and the long-term use is in the production. However, due to the toxic substances contained in the plating solution, the gas escaping from the plating process has great harm to the health of workers, and the waste water must be treated strictly before discharge.
The production process of large coil galvanized wire is relatively simple. The wire after cleaning is put into electroplating solution first. Of course, the plating solution should contain zinc oxide, a direct current of steel, another zinc plate in the plating solution. The zinc is transferred to the surface of the steel as a molecule. If it shows a bright and beautiful color, the wire is coated with zinc.
- 2, galvanized wire mesh molding sheet storage ground should be flat, according to the symbolic requirements of the accumulation of regular, height should not exceed 2M, and away from heat sources, avoid exposure.
- The common type of barbed rope is double-strand barbed rope, and the models are 2.0*2.0mm, 2.25*2.25mm, 2.7*2.25mm, and all of them are galvanized barbed rope (plastic coated barbed rope is rarely used). The barbed distance (that is, the distance between winding wires) is generally 14 cm. Here’s what these models mean:
- For example, if barbed rope is used to circle, the cost per meter is only a few yuan. If other products are used to circle, it may be more than ten yuan or even more than 20 yuan, which undoubtedly increases the cost of users again. Therefore, barbed rope is the most economical product for breeding cattle and sheep.
Post time: 08-05-23- With the progress of the anti-corrosion skills of the cattle fence, the steel wire function of the cattle fence will also improve, so that the life of the progress of the use of great help. The number of years of use is primarily dependent on the environment of use and whether the operation of the construction is standard at the time. The operation standard of progress operation can also extend the number of years of use. The above is a general estimate of the life of the cattle net, I hope to help you.
1. Adjust electroplating process parameters
- The tensile strength of steel wire is high and the hardness is high. In the flattening process, the longitudinal movement resistance of steel wire per unit volume increases and the elongation decreases. The steel wire unit volume will move to the lateral resistance smaller, the width of the increase. On the contrary, the wire is easy to extend lengthwise, and its width decreases. This is the production of high steel wire hardness is easy to wide, small hardness, easy to stretch out of wide reasons. If the tensile strength deviation of steel wire is large, the hardness uniformity of steel wire strip is poor, the width difference of the billet rolled into large, will seriously affect the quality of the billet.
- Galvanized wire is immersed in heated molten zinc, the production speed is fast, the coating is thick but uneven. The thickness of 45 microns allowed by the market, the color is dark, the consumption of zinc metal is more, and the matrix metal is formed into an infiltration layer, and the corrosion resistance is good. The hot dip galvanizing can be maintained for decades in the outdoor environment.
The size of the dog cage is generally relatively small, suitable for indoor small dogs, dog cage is easy to carry, go out to compare the use, folding dog cage high strength steel wire and steel pipe material, the outer layer spray treatment. Strong texture, excellent rust resistance, the dog cage inside the tray, can be pulled out, convenient to clean the dog’s urine and feces, folding, dog cage is suitable for families and pet stores to raise more pet dogs.
- Attention should be paid to line collection and operation. Others shall not get on the train without the monitor’s consent. The wire reel should be put lightly, stacked firmly and neatly, not more than 5 discs. It is forbidden to contact human skin directly with acid and base. When the acid fog exceeds the specified target of the state, timely measures should be taken to control it; otherwise, production is not allowed.
