twin screw extruders have the extruder principles of single screw extruders: conveying solids, melting, pressurizing and pumping, mixing, stripping and degassing, but not easy. Research on twin screw extrusion theory began late, combined with its many types, complex screw geometry and complex extrusion process, which caused many difficulties for research.
Why choose twin screw extruder?
What should I pay attention to when using a twin screw extruder?
What is the use value of a twin screw extruder?
1.The twin screw extruder uses lateral feeding technology, which improves the integrity of the material and greatly increases the performance. The position and shape of the feed opening also have a major influence on feed efficiency. With the same parameters, the feed area increases and the output increases. With the same inlet surface, the rectangular cross-section has a higher loading efficiency than the circular cross-section. The use of the lateral twin screw conveyor is also based on this consideration.
2.The twin screw extruder has strong self-cleaning ability. Since the two threaded sleeves are intertwined, the contact part forms a continuous space curve with even clearance. With the synchronous rotation of the two, the space curve moves along and forms the self-control effect between the screws. At the same time, the glue on the thread surface is cleaned to ensure the properties of residual material.
1. Check. Set the engine, control unit, each pipeline and all components into operation. If there is a sudden power failure during production, the main drive and the heater stop. When the switching power supply is repaired, each part of the cylinder section must be reheated to the required temperature and held for a certain time before the extruder is put into operation.
2.If the instrument panel of twin screw extruder is found, when the needle becomes full, it should be checked whether the contact of the boundary line such as the thermocouple is good.
3.The inner cavity of the cooling tube of the twin screw extruder accessory is very easy to dirty, and the outside is very easy to corrode and corrode. Be careful and careful with daily maintenance. Excessive dirt blocks the pipeline, cannot reach air conditioning and cooling, and strong rust also causes leaks. During daily maintenance, be sure to apply lime cleaning and corrosion protection and temperature reduction measures.
Due to the increased environmental awareness, biodegradable twin screw extruders are gradually being used in all areas of life. The feature of the degradable twin screw extruder is that it can use fully degradable plastic raw materials to produce plastic products with the same function. The traditional plastic granulator needs to be controlled manually, while the biodegradable twin screw extruder is fully automated, which can greatly improve the product quality. In addition, it has a strong durability and can be used for a long time.
Nanjing Haisi Extrusion Equipment Co., Ltd. has been focusing on the development and production of twin screw extruders for several years. And it is committed to providing perfect service to every customer from all over the world.
