Torque wrench in use for a long time, will produce carbon deposition in the clamp wall, prone to thermal cracking, affect the heat transfer efficiency, to accelerate the aging heat medium failure. So we need to clean them regularly to strength tongs. So how do we wash?

In fact, we can choose the treatment method of phosphating, corrosion-resistant, wear-resistant, improve organic coating binding force, electric insulation and lubrication in cold working. Metal on the surface of the oil and solid dirt removal will directly affect the quality of the phosphating, metal surface decontamination process is not only a colloid role, at the same time is a complex role in many simple colloidal aggregation process. Several different colloid at the same time, the interaction between surfactants also emerged, choose to clean up dirt multiphase multicomponent surfactant.
