Read MoreUsing the patented technology of the invention, regularly put zinc block into the plating aid pool, so that the bivalent iron in the plating aid into trivalent iron, and play a stable PH value in a numerical range of an important measure, but also easy to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

Post time: 10-08-22Generally, galvanized wire used for welding is required to have a certain hardness. After acceptance of galvanized wire, the first thing to do is to feel the hand, and the other thing is to test on the machine. Because the average user does not have testing equipment, it is also very inconvenient to test on the machine. Use a micrometer to measure the diameter of galvanized wire evenly, and keep it about 0.02mm above and below the contract signing standard, with neat appearance, no leakage plating and no mess.

After annealing, the wire will become soft, flexibility will increase, iron is a relatively active metal, and more active than hydrogen, so it is a good reducing agent. At room temperature, iron is not easy to react with oxygen, sulfur, chlorine and other non-metallic elements in dry air. Its production cost is lower, its use and scale are also relatively wide, and it has better protective function. Therefore, it is an important material for steel parts in strict working environment.

Bridge bridge reinforcement is durable in poor function and aging, etc., through the wire mesh reinforcement, can prolong the service life of the bridge, avoiding the phenomenon of bridge cracks, subsidence and so on, wire mesh can play an obvious effect of crack in bridge reinforcement engineering, engineering construction speed, to enhance the crack resistance of concrete function, better economic benefit.

In the purchase of large rolls of galvanized wire, see the hardness of galvanized wire first, only after the hardness reaches the standard can be used. The hardness standard of large roll galvanized wire is a very important performance index and an economic test method. But for the hardness of metal materials, there is not a unified and clear definition including all test methods at home and abroad.

It is recommended for use in oil which contains load bearing additives such as EP gear oilsdecreased at low temperature.Vi. Fluoro silicone rubberFluorosilicone rubber, like silica gel, combines- In addition to its functional benefits, the rubber carburetor gasket also plays a role in maintaining the overall health of the engine. By preventing leaks and absorbing vibrations, it helps to reduce wear and tear on the engine's components, extending their lifespan and reducing the need for costly repairs.
