The internal relationship between the reaction process, speed, performance, screw configuration, and operating conditions of the twin-screw extruder during extrusion reaction molding is established, and a model is established to guide the reaction molding extrusion.
The gear transmission system includes a gear box and a distribution box. Mainly to ensure the raw materials, machining accuracy and assembly accuracy of its accessories. Especially for gearboxes, the assembly accuracy is particularly important. The main problem that occurs when the assembly is not in place is the oil leakage of the gearbox. Although it will not have a great impact on production, it will affect the workshop environment.
The electrical control part is equivalent to the heart of the twin-screw extruder, and any damage to the components will affect the operation of the entire equipment. Therefore, its electrical parts need to use imported products to ensure the continuity and durability of the products.
reduce manufacturing cost. When making masterbatches, it is often necessary to change the color, if necessary to change the product, open the open processing area within a few minutes, and also analyze the mixing process by observing the melt profile over the entire screw.
1. After the machine is used for a period of time, a comprehensive inspection should be performed to check the tightness of all screws.
2. In case of interruption of production, the main drive and heating stop. When the power supply is restored, each section of the barrel must be reheated to the specified temperature and kept for a period of time before the twin-screw extruder can be started.
3. After the extruder is used for 500 hours, there will be iron filings or other impurities in the gear box. Therefore, the gear box of the twin-screw extruder should be cleaned and the lubricant of the gear box should be replaced at the same time.
4. If the instrument and pointer of the twin-screw extruder are found to be full of turning, check whether the contact between the thermocouple and other side lines is good.
1. Sundries are not allowed in the material, and hard objects such as metal and sand are strictly prohibited from entering the hopper and extruder.
2. When opening the barrel cover or the air extraction cover, be careful to prevent foreign objects from falling into the host.
3. There must be enough preheating and heating time, and the manual cranking should be brisk before driving. Generally, it should be kept at a constant temperature for 2 hours after reaching the process set temperature.
4. The screw of the twin-screw extruder is only allowed to start at low speed, and the idling time should not exceed 3 minutes.
