The problem of lifting pliers rust is very common, due to the user's maintenance is not in place, lifting pliers are prone to rust, then lifting pliers rust can continue to use? On this question, we have to decide according to the actual situation.

　　First of all, we understand that rust belongs to a process of corrosion, rust belongs to iron oxide, which is generated by a chemical reaction with water in the humid air, and the metal properties of iron oxide are brittle, far less than the original metal properties, so in this case, we must be treated.

　　The impact of different degrees of rust on the lifting pliers is also different, if the rust in the thickness has eroded the lifting pliers 10%, then the lifting pliers can be scrapped, and then continue to use is also a safety hazard.

　　If the degree of rust is less than 10% of the thickness of the lifting pliers, it is necessary to immediately remove the rust treatment, can be delayed, to know that after the iron oxidation reaction into rust, the volume will become larger, the volume will change nature will cause a backlog of the surrounding metal, thus further diffusion, so it is necessary to stop this situation in time.

　　Whether the lifting pliers can continue to use after rust depends on the degree of rust, but no matter how small the degree of rust, it is impossible to ignore its existence, must be dealt with in the first time, and properly kept.
