- “Wet” hot dip galvanizing is also called “molten solvent method” hot dip galvanizing. Iron and steel workpiece through degreasing, pickling and cleaning, it is necessary to set in a special box above the surface of the molten zinc in the “molten solvent” (also called cosolvent), and then into the zinc liquid to galvanized. The molten solvent is usually a mixture of ammonium chloride and zinc chloride, but also other chlorine salts.
- Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives should be used to obtain a coating that meets the requirements of this standard. Light treatment should be carried out after light plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied for activation for 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
We must have a certain understanding of the hexagonal network, we are the beautiful shape of the hexagonal network, more than the appearance of the hexagonal network is very beautiful, in fact, the practical value of survival is very high. To introduce the relevant information should be very clearly know the highway guardrail net, hexagonal wire netting in all kinds of fence netting, in the value of the high-speed on the road more MaoJian, it not only be used in all kinds of road, in a sports ball games venue and try our best to take care of landslides, also has reached very matter effectiveness.
- The reason for the bridge reinforcement is that the bridge durability function is poor and aging, through the steel wire mesh reinforcement, can prolong the service life of the bridge, to avoid the bridge cracks, collapse and other phenomena, steel wire mesh in the bridge reinforcement anti-crack engineering can play an obvious effect, improve the construction speed of the project, enhance the concrete anti-crack function, sum up the economic benefits.
For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering nets, the mesh should be less than 20 and the diameter should be greater than 1 mm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering nets. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.
The characteristics of this kind of small animal cage, is small, light, easy to carry, but also easy to clean care. For small animal cages, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violent”, or the cage under the “destruction” will occur welding or plastic crack off.
Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.
Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
- Hard black galvanized iron wire is made of low carbon steel wire by wire drawing machine. Hard black galvanized iron wire is the first feature of high hardness, bright appearance. It is mainly used for welding clothes hanger, umbrella, metal mesh, basket, basket and other metal products. Soft black galvanized iron wire is made of low carbon steel wire after annealing and softening, and then cold drawing. Soft black galvanized iron wire is the first feature of good flexibility, slightly higher hardness, bright appearance. Mainly used for metal mesh weaving technology, welding net, process products of welding.
- The reason for the bridge reinforcement is that the bridge durability function is poor and aging, through the steel wire mesh reinforcement, can prolong the service life of the bridge, to avoid the bridge cracks, collapse and other phenomena, steel wire mesh in the bridge reinforcement anti-crack engineering can play an obvious effect, improve the construction speed of the project, enhance the concrete anti-crack function, sum up the economic benefits.
The surface coating of galvanized wire can be seen 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. High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer, we can generally judge the quality of galvanized wire.
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)
The barbed rope factory not only provides the sales work of blade barbed rope, including the subsequent construction, but also contracted together, and the construction price is particularly different.
- Since nose touching is an important part of a dog’s social behavior, humans can use this to train them. Experts say that if owners touch their dogs’ noses regularly when they are young, they will have softer personalities and be less likely to hurt when they grow up.

Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
In order to improve the corrosion resistance of steel pipe, the general steel pipe is galvanized. Galvanized steel pipe is divided into hot dip galvanized and electric galvanized. The layer of hot dip galvanized is thick, the cost of electric galvanized is low, and the surface is not very smooth. Used for steel blowing oxygen pipe, generally with small diameter welded steel pipe, specifications from 3/8-2 inches of eight. Made of 08, 10, 15, 20 or 195-Q235 steel strip, in order to prevent corrosion, some should be aluminized.
Twist flower hexagonal network customized quotation needs to provide the following parameters:
When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.
- 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 kind of plating method, not only has the corrosion characteristics of the electric galvanized wire, and because of a zinc 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.
- Bridge reinforcement reason is the bridge durability function is poor and aging, through the steel wire mesh reinforcement, can prolong the service life of the bridge, avoid the bridge cracks, collapse and other phenomena, steel wire mesh in bridge reinforcement anti-crack engineering can play an obvious effect, improve the construction speed of the project, enhance the concrete anti-crack function, induction of good economic benefits.
Compared with the traditional protective device, the advantages of barbed wire protective net are very obvious. First of all, because of the standardized production mode, the barbed wire net is dense after installation. Not conducive to the passage of personnel. The traditional way of protection due to private disorderly construction of the density of the protective net can not play a protective performance. So the installation of barbed wire net is the best choice to protect the home.
Galvanized wire can be used zincate galvanized or chloride galvanized and other processes, appropriate additives should be used to obtain the coating required by the standards of low carbon steel wire. When the galvanized wire out of light plating should be carried out light treatment, the galvanized wire bath to control the temperature. Now the quality level of galvanized wire on the market is not equal, galvanized wire is also called hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities.
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.
At present, there are two main kinds of electric galvanized wire products, hot dip galvanized wire and electric galvanized wire. The difference is that the way of galvanizing is different, and the quality of the products is different. Hot dip galvanized wire zinc layer thick, corrosion resistance is stronger, but correspondingly, the price is high. Galvanized wire zinc coating thin, corrosion resistance is poor, but the price is low.
1: according to the different color of the sprayed blade barbed rope, its price is 2000-2200 yuan higher than the ordinary blade barbed rope, but the cost performance of the sprayed blade barbed rope is much higher.
Post time: 23-05-22- Although galvanized hook mesh is outstanding because of its surface, this does not mean that this hook mesh product is not useful. From the point of view of people’s use of it, this hook mesh products through a surface of galvanized treatment, whether it is wind and sun, or man-made inadvertent damage, will not bring a little harm to it, so the more comprehensive use of galvanized hook mesh products will then be widely used in several fields.
