Corrosive, abrasive and high temperature resistant resins may damage the twin screw barrel screw without knowing it. For example, some engineering materials, thermoplastic elastomers and biopolymer materials sometimes form a corrosive environment. In addition, the reinforcing materials (such as glass fibers, glass balls, etc.), certain fillers and additives are all abrasive.
In order to avoid affecting production efficiency and product quality, these materials must be closely monitored for possible damage to equipment. In order to maintain high processing standards, it is necessary to establish a preventive maintenance program. When necessary, the screw of the twin-screw barrel should be checked and measured, and the screw should be pulled out for re-installation or replacement, because minimal wear will also affect product quality.
The best way to protect equipment from corrosive and abrasive resins is to select the appropriate material to manufacture the twin screw barrel screw. In order to cope with corrosive, abrasive and high temperature resistant melts, manufacturing wear-resistant barrels and screws, the processing cost is about 3 to 4 times higher than the standard polyolefin screw.
This is because wear-resistant alloys are relatively expensive and difficult to process. But they can provide longer service life, and the maintenance interval can be longer.
