  • But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.

  • The utility of the hexagonal net in the playground is very superficial, in each city to build the playground, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal nets, not only can improve the stadium group image, but also convenient city residents to carry out a row of activities.

  • 3. The surface adhesion of stainless steel pet cage contains acid, alkali and salt substances (such as alkali and lime water splashing on the decoration wall), which causes local corrosion.

  • You can also buy a cage from other places. You can choose the cage you like or find suitable on the website. For example, a pet store, supermarket, pet products website, etc., it is recommended that you buy metal cage, with a metal tray underneath, of course can also be of stainless steel and plastic, is plastic easily damaged by the dog bite, plastic tray is easy to be a dog of uric acid corrosion, but also show the low end of the plastic products, beautiful, durable.

  • 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.
