People can carry out reasonable maintenance for themselves according to the methods of fitness exercise and diet maintenance, so as to achieve the actual effect of prolonging life. The same can be said of goods, which can increase their life span according to special "maintenance" methods. Generally speaking, the vast majority of bolt products can survive for 24-2 days under the corrosion of 5% concentration value of salt spray testing machine, in other words, the specific service life of such bolts is about 1-2 years, but if we can carry out moderate maintenance on bolts, we will be able to Open all iron core pulling rivets can reasonably increase their service life. Some specific and reasonable maintenance methods are shared by Dazai with hardware products Co., Ltd

If your enterprise has high regulations on the oxidation resistance of commodities and can carry out metal surface treatment on bolts, which treatment method is actually selected can be deeply analyzed according to the actual problems of product properties. After solving the problem, salt spray test is carried out for bolts. Generally speaking, 24 hours in natural environment is equivalent to one year in geographical environment, which can be controlled according to the actual situation.

2. If it is not necessary, the bolt should be placed in the dry and natural ventilation environment as far as possible, so as to pull the blind rivet, reasonably maintain the thickness of the protective layer of the bolt, and avoid air oxidation.

3. Try to avoid the damage to the bolts. Generally, there is a protective layer thickness on the surface of the bolts to protect the bolts from air oxidation. Therefore, maintaining the consistency of the bolts can actually improve the oxidation resistance of the bolts.
