What requirements should be met by rubber joints?
Although the chemical water treatment of pickling passivation can make the surface clean and bumpy at the level, its prestressing anchor is shallow, and it is easy to air pollute the deposition geography of rubber joints. Different methods of rust removal and methods can cause important harm to pickling passivation and affect many characteristics and factors. Rubber joints produce a very thin protective film on the surface when bright annealing is carried out, and although this protective film is about 3×10-6mm, it is very tough, even if it is destroyed.
 
Therefore, if you understand the characteristics of rubber joints and apply them reasonably, you do not have to worry about rusting when there is little corrosion in water pipes or hot water up to 100℃, and you do not have to worry about reducing the inner diameter or increasing the frictional resistance caused by the common "rusting protrusions" in rubber joints, and you can get flowing water that is not easily blocked.
Generally speaking, first of all, use the millipede wheel or abrasive wheel to carry out coarse polishing, and then slowly use the precision to carry out fine polishing according to the demand of smoothness. Large size rubber joints above the general use of a thousand leaf wheel, rubber joints can be used to make the cloth wheel, to reduce the cost of fees. If you feel that grinding wear-resistant throwing out is not bright enough, fine throwing can be moderately wiped wear-resistant wax to enhance the brightness.
Under the premise of less corrosion such as water pipe or hot water up to 100℃, there is basically no need to worry about rusting, and there is no need to worry about reducing the inner diameter or expanding the frictional resistance caused by the common "rusting protrusions" in the rubber joint, and it is possible to get flowing water that is not easily blocked. When welding rubber joints by electric welding, the rubber joint is introduced into the internal welding, and the residual heat recovery from welding is used to speed up the oxidation of the air in the rubber joint and reduce it to below the airflow.
