PAST AND FUTURE OF EXTRUDER
2024-10-15
I. The Definition of Extruder
Extruder is also known as plastic film molding processing equipment. It is a kind of plastic processing machinery. Its main function is to mix and process plastic fragments or granules of different compositions in a certain proportion, and after a series of processes, finally form plastic sheet or film form products, in order to be reprocessed into a variety of stereotyped plastic products. Plastic extruders can be divided into single-screw, twin-screw and multi-screw extruders according to the number of screws.
Ⅱ. The Basic Introduction of The Extruder
In the plastic machinery, plastic extruder is usually referred to as extruder. Plastic extruder can be basically categorized as twin-screw extruder, single-screw extruder, multi-screw extruder and screwless extruder. Screw extruder is relying on the pressure and shear force generated by the screw rotation, can make the material can be fully plasticized as well as uniform mixing, through the mouth molding. Screw is the heart of the extruder, is the key component of the extruder, screw performance is good or bad, determines an extruder's productivity, plasticization, filler dispersion, melt temperature, power consumption, etc., which can directly affect the scope of application of the extruder and production efficiency. Through the rotation of the screw on the plastic to produce the role of plastic in the machine can occur in the brief movement, pressurization and from which to obtain part of the heat, plastic in the barrel in the process of moving mixed and plasticized, viscous flow state of the melt in the flow through the mouth of the die, the desired shape and molding. At present, China's single-screw extruder is the most widely used, suitable for general material extrusion processing.
Ⅲ. The Characteristics of Extruder Products
The energy saving of the extruder can be divided into two parts: one is the power part and the other is the heating part.
Power part of the energy saving: most of the use of frequency converter, energy saving is through the saving of the motor's residual energy consumption, for example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production is enough to produce, those excess energy consumption will be wasted, the frequency converter is to change the power output of the motor to achieve the effect of energy saving.
Heating part of the energy-saving: heating part of the energy-saving mostly electromagnetic heaters are used to save energy, the energy saving rate is about 30% to 70% of the old resistance circle.
Working Process
Plastic material enters into the extruder from the hopper, and is transported forward by the rotation of the screw. During the forward movement, the material is heated by the barrel, and the shear and compression brought by the screw makes the material melt, thus realizing the change among the three states of glassy state, high elasticity state, and viscous flow state.
Under pressure, the material in the viscous flow state passes through the mouth mold with a certain shape, and then becomes a continuous body with a cross-section similar to the shape of the mouth according to the mouth mold. Then, it is cooled and shaped to form a glassy state, and the desired processed part is obtained.
