The market demand and development speed in different regions and fields may vary, but with technological progress and market promotion, wood-plastic products are expected to be applied and developed in more fields. In the actual market development, enterprises need to continuously improve their technical level, product quality and innovation capabilities to better meet consumer needs and cope with market competition.
A:In the plastic product extrusion process, it is important for stably and continuously production, so the engineer need to solve the problems quickly when there is failure of plastic extrusion. To quickly and accurately determine the cause of the failure of the plastic extruder, you can follow the following steps: 1. First, observe the phenomenon.
1. Unstable extrusion volume: It may be due to uneven feeding, such as fluctuations in feeding speed, blockage of feed port, uneven size of raw material particles, etc.; it may also be caused by wear of the extruder screw, unstable screw speed, or uneven barrel heating temperature. 2. Plastic scorching: If the barrel temperature is too high, the screw speed is too fast, the gap between the screw and the barrel is too small, or the material stays in the barrel for too long, it may cause plastic scorching, causing the product to change color, decompose and other problems.
A:Lubricant is one of the most important additives in composite plastics. It is correlated and influenced with other auxiliaries. For example, in conjunction with antioxidants, reduce oxidation; Combine with plasticizer to improve flexibility. Its type and dosage will also affect the dispersion of other auxiliaries, which will affect the performance of plastics, and play a key role in the composite auxiliaries system.
A:Rubber mold is mainly divided into pressing mold, injection molding mold, extrusion molding mold, die casting mold and transfer molding mold. Pressing is suitable for simple products, injection molding is used for high-precision complex products, extrusion molding produces continuous long strip products, die-casting molding produces large products, transfer molding is suitable for high-precision products.
A:Conical twin screw extruder is an important equipment for plastic processing. Its structure is unique, two conical screw fit each other. With excellent plasticizing and mixing capabilities, can adapt to a variety of plastic processing, high yield and good self-cleaning. Widely used in pipe, plate and other products production, for the plastic industry to bring efficient and high-quality processing solutions.
