- Dip is one of the anticorrosion methods of galvanized diamond net. For hook mesh immersion is one of the methods of anti-corrosion, now the domestic more mature method is: powder immersion method, it originated from the fluidized bed method, the so-called fluidized bed is used in the Winkler gas furnace on the oil contact decomposition, and then developed the solid-gas two-phase contact process, gradually used in metal coating. So sometimes it is still called “fluidized bed coating method”, the actual process is to add the powder coating to the bottom of the porous, breathable container, the blower from the bottom into the treated compressed air, so that the powder coating turned to the “fluidization state”. It becomes a fine, evenly distributed powder.
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire) is made of low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. The products are widely used in construction, handicrafts, wire mesh, galvanized hook mesh, spackle mesh, highway fence, product packaging and daily civilian and other fields.
- If adult dogs touch noses with puppies out of affection, adult dogs touch noses with dogs that have more meaning in life. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
Galvanized iron wire will rust, mainly and the thickness of galvanized layer and the use of the environment, galvanized iron wire is also divided into cold galvanized iron wire and hot galvanized iron wire, in general, hot galvanized iron wire galvanized layer is thicker, rust prevention time is longer, generally can be 7 or 8 years without rust. If the galvanized layer is damaged, or long-term use in a humid environment, it will accelerate the rust time of galvanized iron wire.
The application of cold wire drawing is very wide today. What problems need to be paid attention to in the acceptance of cold wire drawing in galvanizing plant?
- 3, twisting hexagonal net factory weight, the greater the weight, the more sufficient material.
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.
Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance is often called stainless steel, and the steel with chemical corrosion resistance is called acid resistant steel. And galvanized wire has good toughness and elasticity, zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Products are widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields.
From the plastic spraying, spraying blade gill net (pvc blade gill net, plastic blade gill net), also known as spraying blade barbed wire, spraying blade barbed wire is produced in the future, to rust treatment by the attack. Spray appearance treatment makes it have quite good anticorrosion ability, beautiful appearance, good waterproof effect, easy construction, economic and practical excellent characteristics. Spray blade thorn rope is a plastic powder spray on the product blade thorn rope of an appearance treatment method.
Post time: 06-05-22In order to remove defects such as surface film layer and surface inclusion of large roll galvanized wire, it can be treated by conventional technology. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion. Activated carbon mat to remove surface active substances, or through filtration to make the foam less stable, these are effective measures; Other measures should also be taken to minimize the intake of surface active substances. The electroplating speed can be significantly reduced by the introduction of organic matter.
- 2.7*2.25mm means that the two strands are 2.7mm silk, and the thorns are 2.25mm silk.
Bird cage is a kind of pet cage, is the main environment for ornamental birds to carry out activities and habitat, “work to do a good job, must first sharpen its tools” bird equipment is applicable or not, is one of the key to raise ornamental birds. Therefore, only if the appropriate cage and other accessories are prepared first, can the birds be kept healthy and lively, singing freely and suitable for viewing. There are many kinds of cages, depending on their body shape and habits.
- Choose a cage with a proper structure, such as a tray under the cage so that the dog can urinate in the cage. It’s also easy for the owner to clean up.
Post time: 17-03-23Two is to pay attention to the storage and use of galvanized wire products, according to the actual environmental standards to choose different specifications of galvanized wire products;
- 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.
Post time: 17-06-24- The steel mesh improves shock resistance and crack resistance. The longitudinal and transverse steel bars of the welded steel mesh constitute a network structure. Therefore, the bond anchorage between the steel mesh and concrete is good, and the load distribution is uniform, which significantly improves the earthquake resistance and crack resistance of the reinforced concrete structure. According to the practice test, the cracks of welding net are reduced by more than 75% than that of manual binding net. Greatly reduce the unnecessary cost of the construction process, shorten the construction cycle, the use of steel wire mesh is simple and convenient, easy to transport.
- In summary, as a commonly used anticorrosive material, electrogalvanized wire has good corrosion resistance. Its corrosion resistance mainly depends on the thickness, uniformity and structure of zinc layer, substrate material and environmental conditions and other factors. Through reasonable electroplating process and material selection, the corrosion resistance of electrogalvanized wire can be improved and its service life can be extended.
Cold galvanizing is in the plating tank through the current unidirectional zinc gradually plated on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, smooth, high aesthetics, poor corrosion resistance, generally a few months will rust. Hot dip galvanized coating is thicker, generally 30-60 microns, coating corrosion resistance is higher. Suitable for outdoor work of steel parts, such as highway fences, power towers, large size fasteners and other more “rough” workpiece long-term rust prevention.
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.
- Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
There are still some differences between the welding mesh and the wire mesh and the steel mesh. This mesh is mainly a welding mesh made of high quality low carbon steel wire straightened and cut, and then welded with electric welding equipment. It can be said that because of the characteristics of fast production and convenient transportation, it has been applied to many industries. The application of welding mesh in the industry, because the mesh has strong corrosion resistance and uniform mesh. It has become a special grid for floor heating in the building industry and has been applied in many fields.
- The above is how to prevent the rust of galvanized iron wire when stored and used. Of course, the choice of high-quality galvanized iron wire can also prevent the problem of zinc removal and rust of galvanized iron wire.
