Machine processing after the appearance of metal available chemical disposal: the first is using acidic or alkaline solution and the workpiece surface oxides and oil produce chemical reaction and make it dissolve in acid or alkaline solution and to reach to remove the purpose of workpiece surface rust oxide skin and oil. Chemical disposal is in compliance with the clearing of the sheet metal, but the defects are: if the time control is improper, even if the corrosion inhibitor, can also make the steel attack corrosion phenomenon.
Method: the primary mechanical disposal including blasting method and shot peening method. Blasting method is used to accelerate the liquidation of the projectile centripetal force, projectile to stop clearing the way the workpiece cleaning. But shot poor sensitivity, constrained by the place and clearing work some consciousness, in workpiece inner and outer surface easy to attack the liquidation to the dead. Equipment structure messy, wearing parts, especially the blade and other parts wear and tear, repair man hours, high cost, one-time investment.
These two methods, in the practice of the use of base, regardless of you are the choice of what kind of approach to deal with, are all have a lot of local we go to pay attention.
In the process of the internship, the choice of chemical method for disposal, is able to use the machine will be completely clean surface treatment. However, in practice the process of using, we need to pay attention to a question is to doubt excellent control of the time, you know, place the device in the acidic or alkaline solution for processing. If it is not a good command of the time of the doubt, is very simple equipment corrosion situation. Therefore, in the practice of the use of base, it is best to ask those professionals to deal with.
If it is the choice of mechanical disposal, in the course of the internship, there are a lot of limitations. You know, in the use of the centripetal force will accelerate the process of the projectile, the sensitivity of blasting, is poor. Moreover, in the practice of the operation, but also by the origin of the limitations and so on. For example, for those with acidic or alkaline solution, and machine workpiece surface oxides and oil produce chemical reaction, then, excellent material can be dissolved in acidic or alkaline solution. This can be an excellent arrived removed workpiece surface rust oxide skin and oil the. However, in the course of the operation of the sub machine practice, if you can not excellent control of the amount of drugs used, it is best not to use this approach to deal with. Otherwise, there will be a corrosion situation.
