After annealing, iron wire will become soft, flexibility will increase, iron is a more active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron in the dry air is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements, its production cost is lower, use and scale is wider, better protection function, so it is an important material for iron and steel parts in a strict working environment.
Post time: 30-01-23Speaking of pets, we have to talk about parrots. Because it’s easy to take care of, and it can talk, talk to you, and make you laugh. Parrots love to climb, so there is a cage with bars that are made up of horizontal bars rather than vertical bars, because this makes climbing easier for the parrots.
- Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outdoor blade thorn rope will cause the woven bag to become ineffective, resulting in the internal blade thorn rope exposed to affect the later use.
Post time: 19-12-22Razor blade barbed rope has been widely used in military sites, prisons, government agencies, banks in the world. The walls of living quarters, private homes, villas, fences, doors and Windows, highways, railway guardrail and border lines and other protection and security.
Galvanized iron wire is a substance we often see in life. It is the zinc gradually plated on the metal surface through the unidirectional current in the electroplating tank. The production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 microns, the appearance is bright, the corrosion resistance is poor, and the corrosion will rust in a few months. Galvanized wire has the characteristics of thick galvanized layer, strong corrosion resistance, strong galvanized layer, etc., the products are widely used in construction, highway walls, Zahua, weaving nets.
Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.
- The cost of blade thorn rope is much more troublesome than ordinary thorn rope, mainly because the raw materials and processes are more factors.
The 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.
- In use, it can be well used to control the degree of softness and hardness in the annealing process, mainly used for binding silk and binding wire in the construction industry. Its use is not limited to handicrafts, of course, in the construction industry is also widely used. In the early days, the lanterns were made with wire outside and proper candles were placed inside. People hung them in front of the door and it was very beautiful to go up at night.

- The electrolytic deposition of large roll galvanized wire zinc-chin layer is basically the following two kinds of electrolyte: zinc is mainly in the form of zinc cation hydration in the solution; Zinc is mainly present in solution as complex anion. Acid electrolyte belongs to one class, complex cyanide and zincate electrolyte, and nickel sulfate electrolyte constitute the second class. Cyanide electrolyte and acid electrolyte are of great significance.
Post time: 02-09-22Stainless steel is short for rust acid steel, air, steam, water and other weak corrosion medium or stainless steel is called stainless steel; And the chemical corrosion resistance medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid steel.
- 3, whether positive and negative twist, whether bilateral silk is needed.
- 5, there are no special requirements: such as whether to shrink packaging, etc.
Post time: 03-04-23- In the processing of stainless steel barbed wire after cold galvanized or hot galvanized coating on the surface of the last zinc material, not only beautiful but also plays a good protective role.
Because of its light weight, strength is relatively large has gradually begun to replace the original column. At the same time, due to the relatively uniform specifications, the barbed rope installation is also more beautiful. The direct spacing of the barbed rope is relatively fixed, which can effectively prevent crossing. At the same time, the mesh at the bottom is relatively dense, while the mesh at the top is relatively loose, which can save resources.
- Four: spray blade barbed rope long service life.
- 2, pasture installation of thorn rope spacing, if it is cattle or horses due to the larger size, the spacing can be appropriately relaxed. But if it’s a sheep, it’s a smaller animal and you have to make it a little bit narrower.
