Protection method of twin screw barrel screw
Protection method of twin screw barrel screwCorrosive, abrasive and high temperature resistant resin may damage the twin screw barrel screw unintentionally. For example, some engineering materials, thermoplastic elastomers and biopolymer materials sometimes form a corrosive environment. In addition, reinforcing materials (such as glass fibers, glass balls, etc.), certain fillers and additives are all abrasive.
In order to avoid affecting the production efficiency and product quality, these materials must be closely monitored for possible damage to the 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 inspected and measured, and the screw should be pulled out for re-installation or replacement, because minimal wear will also affect product quality.
To protect the equipment from corrosive and abrasive resin damage, the best way is to choose the appropriate material to manufacture the twin screw barrel screw. In order to cope with corrosive, abrasive and high temperature resistant melts, the manufacturing cost of wear-resistant barrels and screws is about 3 to 4 times higher than that of standard polyolefin screws. This is because wear-resistant alloys are relatively expensive and difficult to process. But they can provide a longer service life, and the maintenance interval can be longer.
