Liter internal mixer
The main and auxiliary threads have equal lifts. The width of the liquid phase groove and the solid phase groove of the screw groove remain unchanged. Starting from the compression section, the depth of the solid phase groove gradually becomes shallower, while the liquid phase groove The depth gradually becomes deeper until the end of the homogenization section. This structure is good for products with high transparency and raw materials with poor thermal stability. In addition, the separation screw design has strong adaptability to raw materials and needs to reasonably select the screw parameters according to the actual situation, including compression ratio, distribution of three stages, and position of the secondary screw edges. 3. Structure and application of double-wave screw. The structural feature of double-wave screw is that a parallel secondary helix is added to the groove of single-wave screw, and the pitch is equal. The secondary helix is lower than the main helix, and the wave crest of one groove is Corresponds to the trough of another spiral channel. During the plasticizing process, not only the materials on the main and auxiliary screws are sheared periodically, but also the materials on the main and auxiliary screws can be continuously merged, which is conducive to homogenization. Therefore, compared with other screws, it can not only improve the plasticizing capacity , and can increase the mixing effect. It is suitable for injection molding of fillers, pigments, and foamed materials to obtain uniform components. It is also suitable for heat-sensitive raw materials to reduce degradation. This type of screw requires relatively high processing accuracy and is difficult to process, so it is used relatively rarely. How to increase the flow rate during injection molding? There are two ways to increase the flow rate during injection molding: if it is low-grade, you can directly add wax and fill the masterbatch. Filling the masterbatch can increase fluidity. If the quantity is larger, the quality will be better. A certain amount of brightener needs to be added. In order to ensure the health and safety of plastic workers, plastic products must not only use various plastic polymers as raw materials, but also add various ingredients, such as pigments. Gas-generating agent and stabilizer that retards ignition. Can't wait for thousands of chemicals. When transporting and using these chemicals, a large amount of chemical powder vapor may be generated, as well as smoke and decomposition products released when the plastic is decomposed by heat. In the case of long-term inhalation of large amounts, it may invisibly damage the health of workers. These substances present in the air of the workplace are difficult to detect unless they are analyzed by scientific instruments. Three: Internal mixer load test operation
Internal mixer
: After the internal mixer has passed the no-load test operation, the load test operation can be carried out. During load test operation, each piece of equipment must undergo continuous load operation of no less than the load. During the load test operation of the internal mixer, the rotation speed should be adjusted from low speed to high speed, and soft materials should be tested first and then hard materials should be tested. : During the load test operation of the internal mixer, the amount of glue added gradually increases from the working volume to full load. The internal mixer should have an interlocking device that starts the lubricating oil pump first before starting the main motor, and runs idling at the same time before adding materials for load test operation. After the last truck of rubber mixing is completed, it will be idle and then shut down. During dry operation, the end face seal lubrication system continues to inject oil into the sealing surface to clean and lubricate the sealing end face. During load test operation of the internal mixer, the following items should be checked: Whether the basic technical parameters meet the requirements of the internal mixer. The temperature rise of the rotor bearing should be ℃. : The temperature rise of the reducer bearing should be ℃. : Rotor, reducer bearing maximum temperature ℃. The oil temperature in the hydraulic system tank is ℃. The maximum temperature of the fixed ring of the rotor end seal device is ℃.
