1.Soft and weak, with certain toughness, no cutting property, no damage to treated workpieces, it will reduce the defect rate of the treated workpieces
2. Not only remove the burrs and throns on the surface of treated workpiece,but also no damage to treated workpieces. Low dust generated in the cleaning process.
PA Nylon sand has certain toughness and non-cutting properties, it will not cause damage to the product to be processed during use, at the same time, it has a long service life.
It is mainly used in below fields:
1. To clean the burr and overflow glue on the surface, holes and recesses of plastic, bakelite, resin and other products;
Nylon sand will generate static electricity in the process of recycling; that is, there will be a lot of powder adhere to the surface of the product and it is difficult to clean up. Using an appropriate amount of antistatic liquid at the same time during use can prevent this from happening, and can make the machine in a long Maintain normal temperature during use to maintain the machine and extend its life.
