There is also a straight blade stabbing rope, which is mainly because the board and wire are not wound in the process of wrapping, so the blade stabbing rope produced is a straight product. The length of the barbed rope of this specification cannot be too long due to the limitation of logistics, and it cannot be bent because it is easy to be deformed by force. This is also the main reason why the barbed rope of the straight blade is not whole or long. Customers are advised to determine the spacing before purchase to prevent losses caused by no calculation.

Large rolls of galvanized silk play a very important role in our life. Made of low carbon steel rod processing, after drawing forming, pickling rust removal, high temperature annealing, hot dip galvanized. Cooling and other process processes. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire). Galvanized iron wire has good toughness and elasticity, the amount of zinc can reach 300 g/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.

When the large roll galvanized wire galvanizing process coating foaming, first check the bath temperature. If the bath temperature is not low, then strengthen the plating before removing oil, prevent the matrix metal in acid corrosion. If you pay attention to these problems, the foaming phenomenon still exists, it should pay attention to the amount and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, in order to reduce the content of additives, observe whether the foaming phenomenon is improved. If there is still no improvement, it is necessary to check whether the storage period of additives is too long, or whether there are too many impurities in the additives.
