How to deal with the metal appearance of the dividing machine?

The metal surface can be chemically treated: first, the acid-base solution reacts with the oxide and grease on the workpiece surface and dissolves in the acid or alkaline solution, so as to remove the rust, scale and oil on the workpiece surface. The chemical treatment is in line with the liquefaction of metal plate, but the disadvantage is that if the time is not controlled properly, the steel will be corroded even if corrosion inhibitor is added.

Mechanical treatment methods: mainly shot blasting and shot blasting. Shot blasting is a method of accelerating shot blasting and shot blasting by centripetal force until the workpiece stops derusting and cleaning. However, the sensitivity of shot blasting is poor. Due to the limitation of the site, there is some consciousness when cleaning the workpiece, and it is easy to have dead corners on the inner and outer surfaces of the workpiece. The equipment structure is chaotic and there are many vulnerable parts, especially vulnerable parts such as blades, which wear quickly, take a lot of maintenance time, have high cost and large one-time investment.

In the practice base, no matter what method you choose to deal with these two methods, there are many places worthy of our attention.

In practice, if we choose chemical treatment, it will help to thoroughly clean the surface of the paperboard machine. However, in the process of internship application, one problem we need to pay attention to is the control of time. We should know that the equipment is treated in those acidic or alkaline solutions. If the problem of time is not well controlled, it is very simple equipment corrosion. Therefore, in the internship base, it is best to let those professionals deal with it.

In the actual operation process, there are many limitations if the mechanical treatment method is selected. It should be noted that the sensitivity of shot blasting is poor in the process of accelerating the projectile by centripetal force. In addition, in the process of practice, there will be limitations in origin and so on. For example, if the acidic or alkaline solution reacts with the oxide and oil on the surface of the plate splitter, the material can be dissolved in the acidic or alkaline solution, so as to remove the rust, scale and oil on the surface of the workpiece. However, in the operation process of board exercise, if the dosage cannot be controlled, it is best not to deal with it in this way. Otherwise, there will be corrosion.
