Therefore, the rust of galvanized black iron wire has a great relationship with storage. At the same time, after rust, it should also be reasonable for post-treatment to avoid affecting its use effect. Of course, when the black iron wire is galvanized, the thickness of the galvanized layer should be ensured, so that the possibility of rust can be reduced. Speaking of galvanized iron wire, perhaps many people think it is relatively rare, in fact, it is not.
- The use of bundled galvanized wire with the development of industry and agriculture also expanded accordingly. Therefore, galvanized wire products in the industry, such as chemical equipment, oil processing, Marine exploration, transport, electricity, shipbuilding, metal structure, etc.), agriculture (such as sprinkler irrigation, dim room, building (such as water and gas transport, wire casing, scaffolding, house, etc.), Bridges, shipping, etc., has been widely use in recent years. Because galvanized wire goods have beautiful surface, good corrosion resistance and other characteristics, its use scale is more and more extensive.
Post time: 19-04-23The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.
- The uniformity of galvanized wire is reflected in what aspects:
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.
- 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.
Post time: 14-10-22- 2, line diameter, mesh spacing (refers to the edge of the twist to the opposite side of the distance).
1, galvanized wire mesh molding sheet must be packed with flat hard data, to avoid eternal deformation due to poor packaging.
- Galvanized hexagonal mesh uses: building wall fixed, heat preservation, heat insulation; Power plant piping, boiler heating; Anti-freezing, residential protection, landscaping protection; Raise chicken and duck, isolate chicken and duck house, play the role of protecting poultry; Protect and support seawalls, hillsides, roads and Bridges and other waterworks.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
After electric galvanizing hot galvanizing. Electroplated copper and other common applications of screen consumption. The weaving of the binding of the building steel wire mesh has the first braided after plating, plating after weaving and other methods, after the disposal of the wire mesh or wire mesh has good corrosion, oxidation resistance characteristics, can be used in the construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries of reinforcement, protection and insulation.
Post time: 06-01-23- Application scope of hot wire: Because the coating is thicker, hot galvanized has better protective performance than electric galvanized, so it is an important protective coating for steel parts used in harsh working conditions. Hot galvanized products in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries have a wide range of applications, in the agricultural field such as pesticide irrigation, greenhouse and construction such as water and gas transmission, wire casing, scaffolding, bridge, highway guardrail and other aspects, in recent years has been widely used.
- Aquaculture galvanized welding mesh is still in construction projects and has been well used. It is because of such a net that it can now save time and effort in construction projects. Not only in this industry, such as breeding and breeding in nursery stock and supermarket shelves, have begun to use such nets, to meet the needs of the industry, but also can well help people in their work.
In fact, there are not too many kinds of plastic coated thorn rope in color, often seen as grass green and fruit green, export types have white, orange, dark green.
- U nail price selection of galvanized iron wire, hot dip galvanized iron wire and black iron wire and other high-quality wire, welded, PVC or PE, PP powder after curing coated its surface, with strong adhesion, good corrosion resistance, bright color and so on.
The prepared black wire welding net is placed in environmental protection galvanized equipment for galvanized treatment. The surface of galvanized welding net is evenly covered with a layer of metal zinc. The corrosion resistance of zinc is very good and it is not easy to be oxidized. The wire diameter error of galvanized welding mesh is very strict, and the gap should be controlled at about 0.02 mm. But whether the tension of an electric welding mesh is qualified, can only be tested by professional tools.
- ③ The galvanized iron wire shall not be damaged when it is tightened.
- Of course, the quality of any kind of product is also affected by the implementation of the specification by the manufacturer. If the manufacturer of electric welding mesh has no high implementation specification in the production itself, or the procedure specification has declined in the production line, or there is no higher requirement on the production link.
3. Salt water or alkali washing: In order to remove the residual acid in the dissolution tank, it is necessary to carry out salt water or alkali washing treatment on the steel wire to ensure that the surface of the steel wire is clean.
Post time: 19-04-23- 5, according to the thickness of the wire diameter to adjust zinc dipping time
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
