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.
They are good at expressing unspoken feelings to people. Their owners feel respect, dependence, admiration and affection. The process of caring for pets inspires people’s sense of responsibility, brings more meaning to people’s life, and helps people establish the fulcrum of life and confidence in life. In fact, dogs are very malleable animals. Through scientific and rational training, you can become a popular family member.
The use of electric welding mesh is very widely, but also used in different industries, different places, many times the name is named because of the use or use, so the use of electric welding mesh is doomed to a variety of different names. Can be called row welding mesh, or zinc plating welding mesh or galvanized welding mesh. There’s also the outer wall wire, which is just used for insulation, usually placed on the outside of the wall, to reduce heat emission.
When large rolls of galvanized wire are used to bind and reinforce the goods, corresponding binding methods should be selected according to the fastening node conditions of the strengthened goods, such as opening binding, opening binding, insertion binding and so on. The insulation layer of semi-hard and soft insulation products shall be based on the diameter of the steel pipe and the size of the equipment. Large rolls of galvanized wire or glue are tied together with a width of 60mm. The binding interval of semi-hard insulating products shall not exceed 300 mm; The larger length of felt and cushion shall not exceed 200mm, and the number of belts shall not be less than 2.
Some customers may not use the blade rope immediately when they buy it, some are retail, and some are temporarily not used in site construction. At this time, it is necessary for customers to follow up the characteristics of the blade rope for storage. Because they are afraid of rain, so this is needless to say, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent outdoor exposure to sunlight will cause the woven bag to become ineffective, resulting in the internal blade of the rope exposed to affect the later use.
In use, there is no need for daily maintenance and maintenance, not only can save a lot of time, but also can reduce costs, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different types, can choose according to their own needs. With good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, in the production of annealing wire is made of steel wire, now more used in the construction industry binding use, compared with ordinary wire is also more soft, have better luster.
The cat cage is novel in shape, exquisitely crafted, exquisite in materials, luxurious and generous, and is an ideal choice for you to raise pet cats. Generally, high-quality steel wire is selected, and the surface is treated by spraying, dipping, chrome plating, galvanizing, and imitation gold. Cats have become an extremely widespread pet in families all over the world. There are fat pads on the bottom of their toes, so they walk silently. When catching mice, they will not startle them, and have sharp nails on the toes.
We must have a certain understanding of the hexagonal network, we are the beautiful appearance of the hexagonal network, hexagonal network is not only very beautiful appearance, 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.
In sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, galvanized wire galvanized layer is easy to be corroded. The uniformity of the galvanized layer on the surface of galvanized wire and the color of galvanized wire, the galvanized layer on the surface of high-quality galvanized wire is uniform, zinc adhesion is good, and the color is white, there is no leakage plating and rust points and other problems.
