Especially in some dark, wet and cold environment with high pH value, the bolt will be corroded in a flash. Once the bolt is rusted, the quality of all the products bearing on the bolt may be seriously damaged, and the stainless steel double drum core pulling rivet will be damaged immediately. Therefore, how to improve the alkali resistance of the bolt has become an unavoidable consideration for many manufacturers One of the key problems!

At present, electroplating process is a common method to improve the alkali resistance of bolts. Electroplating process includes nickel plating, hot-dip galvanizing, copper plating, imitation gold plating and other solutions. Among them, the actual effect of environmental protection of white blue zinc on acid resistance is that it can achieve the salt spray test level above two days. In addition to the electroplating process, oil pump and spray painting can improve the alkali resistance of bolts, and the products with high acid resistance can be applied in many aspects, which can achieve unexpected actual effect. Naturally, in order to improve the alkali resistance of bolts, metal surface treatment alone is not enough, and material selection is also very important. New environmental protection materials such as environmental protection et line are excellent in acid resistance. Therefore, if you have high regulations, you don't have to pay for low cost, you have to spend money, and you can't save quality any more. Riveting well does not mean that you can be carefree. The maintenance of lantern rivets in the middle and later period is also very important. If there is no special situation, try to avoid the damage to the bolt, and try to put the bolt in a dry and natural ventilation environment to reduce the damage to the bolt coating.
