Post time: 12-12-22 - Galvanized wire is coated with a layer of stable zinc on the outside of the wire, and the zinc layer is used to protect the wire and make the service life of the wire longer. In the production of galvanized wire, the wire should be pickled. Pickling is to use some acid mist or acid liquid to wash away some oxides on the surface of iron, that is, rust, and some other corrosion, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanized.
- In addition to these reasons, we should also pay attention to the tooling and process must be stable, and regular testing should be done to ensure the uniformity of galvanized layer.

Most people in addition to pay attention to the price of barbed rope, many people for hot-dip galvanized barbed rope or cold galvanized barbed rope will have questions, in fact, these two products, the price difference is not very big, so how to choose hot-dip galvanized barbed rope and electric galvanized barbed rope?
-
Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

Post time: 17-05-23 - Barbed rope manufacturers specializing in galvanized barbed rope, hot dip galvanized barbed rope, blade barbed rope, stainless steel barbed rope, plastic coated barbed rope, positive and negative twisted barbed rope production for ten years.
- Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.
- Hexagonal hulanwang custom applications in the channel slope protection work plays a very important role, according to the network performance, it can make is not firmly grasp soil erosion, so hexagonal hulanwang custom slope protection effect is very significant, but also because of this advantage, is widely used in such as channel protection, river bank protection, protection of landslides.
- If adult dogs and puppies touch noses out of love, then adult dog nose touching is more meaningful. For example, dogs can touch their noses to communicate where food is safe and whether people or other animals are in danger.
