Cutting Performance of PE Film Blower

Release date:2019-08-16 00:00 Source: Click:

PE film blower enters the screw from the hopper. When the raw material contacts with the screw rib, the rotating oblique edge pushes the raw material particles forward. During the pushing process, the raw material gradually melts through extrusion, friction, heating and external heating. The melted raw material is extruded from the die mouth, and then it is blown, cooled by the air ring, pulled up by the traction frame, pulled roll and retrieved. The reel rack is rolled into thin film barrel material.


The cold air is blown into the membrane bubble by the intake fan, and the hot air is discharged by the exhaust fan. The gas in and out of the membrane bubble is continuously exchanged to achieve a dynamic balance. If there is no internal cooling and exhaust air, more and more air will be in the membrane bubble, leading to no winding, the air must be consistent in and out. Extrusion of various plastics, such as pp, po, pvc, etc. It also has high temperature resistance and no distortion at high temperature.


Abrasion resistance, long service life; corrosion resistance, corrosive material; high strength, can withstand large torque, high speed; good cutting performance; small residual stress after heat treatment, small thermal deformation, etc. A good screw should have high plasticizing ability. It should be pointed out that low temperature extrusion is a developing trend at present.


It can improve the quality of extruded products (such as reducing internal stress), prevent thermal sensitive materials from overheating decomposition, reduce energy consumption, reduce the burden of cooling system of main and auxiliary machines, and improve productivity. Unit consumption unit consumption refers to the energy consumption per kilogram of plastic (rubber) extruded, generally expressed in N. Among them, N is power (kilowatt) and Q is output (kilowatt/hour).


The so-called screw adaptability refers to the screw's adaptability to processing different plastics, matching different machine heads and different products. Generally speaking, the stronger the adaptability, the lower the plasticizing efficiency. Therefore, we always hope that a good screw, its adaptability and high plasticizing efficiency should be both.
