Metal surface treatment method of PCB depaneler machine

Chemical treatment can be carried out after passing through the diaphragm treatment: first, acidic or alkaline solution is used to react with oxides and oil stains on the workpiece surface to dissolve them in acidic or alkaline solution. The purpose of removing surface rust is to remove scale and oil stains. Chemical treatment is based on the flatness of sheet parts, but the disadvantage is that if the time cannot be properly controlled, even if corrosion inhibitors are added, excessive corrosion of steel will occur.

Mechanical disposal methods: firstly, it includes shot blasting and shot blasting. Shot blasting is a method that uses centripetal force to accelerate the shot and project it onto the workpiece to stop rust removal and solidification. However, shot blasting is less sensitive and limited by this location. There is a certain awareness when cleaning the workpiece, and it is easy to occur inside and outside the workpiece. The equipment structure is chaotic, there are many vulnerable parts, especially blades and other parts, which wear quickly, take a long time to repair, have high cost and large one-time investment.

Based on the application of these two methods in practice, no matter which method you choose to deal with, there are many places to pay attention to.

In the process of operation, if chemical treatment is adopted, the surface of the PCB depaneler machine can be effectively and thoroughly cleaned. However, one of the problems we need to pay attention to during operation is to have accurate time control. Please note that the equipment is treated in an acidic or alkaline solution. If the time problem cannot be controlled, it will be easier to corrode the equipment. Therefore, based on the application of internship, it is best to invite those professionals to deal with it.

If mechanical disposal methods are used, there will be many restrictions during the internship operation. It should be known that the sensitivity of shot blasting is very poor in the process of using centripetal force to accelerate shot. In addition, there will also be restrictions on origin during the internship operation. For example, use substances with acidic or alkaline solution, chemical reaction with oxides on the surface of the PCB depaneler machine workpiece and greasy dirt. In this case, the substance can be dissolved in acidic or alkaline solution, so the purpose of removing rust scale and grease on the workpiece surface can be achieved. However, during the internship, if you can't control the dose between the two, try not to use this method. Corrosion will occur.
