In recent years, engineering plastics extruders have become more and more widely used and have a very important role to play in plastic recycling. We all know that plastics can be quite harmful to the environment, but we really can't say exactly what the hazards are, and they are precisely the reasons why engineer plastic extruders are used to recycle plastics.

Elastomer extruders are often used in the process when there are a variety of reasons for a variety of small problems. For example, the plastic products in the production process are not stable, the ups and downs lead to uneven production of products is a relatively common problem. When we encounter this problem, how should we troubleshoot the problem to solve it? The causes of unstable extrusion of elastomer extruders are several common, and we can gradually eliminate them.

The advantage of engineering plastics is that they can act as a structural member under stress, and can maintain dimensional stability for a long time with unchanged performance. The tensile strength of engineering plastics is more than 40MPa, with excellent comprehensive mechanical properties, corrosion resistance, good electrical insulation, and high and low-temperature resistance. They are widely used in automobiles, aerospace, household appliances, mechanical construction, and the chemical industry for various structural parts, transmission parts, insulating parts, corrosion-resistant parts, seals, etc.

How to reduce the energy consumption of underwater pelletizing machines and improve the environmental pollution problem is gradually becoming a major concern. As the global petrochemical occupation is unusually rapid, the demand for granulators is rapidly increasing, the underwater granulator is getting bigger and bigger, and users are demanding more and more mechanical stability and energy-saving and cost reduction. underwater pelletizer does not use substances for basic transformation, but also all, multi-level energy-saving skills transformation, vigorously carry out underwater pelletizer using renewable energy and industrial thermal energy skills. So, how does the underwater granulator reach the effect of saving energy?

Most recycling tasks use pellets as an intermediate product. For some materials, a plastic recycling twin-screw extruder can be followed by a pellet cutting system or downstream flake extrusion. In the case of PET bottle flake recycling, it can produce PET pellets or directly manufacture PET flakes. Twin-screw extruders are developed on the basis of single-screw extruders, which have numerous advantages that cannot be ignored compared to single-screw extruders.

PBAT/PLA films and PBAT/PLA/CaCO3 composite films were prepared by melt blending and blow molding, and the effects of CaCO3 on the thermal stability, mechanical properties and rheological properties of PBAT/PLA blends were investigated.

PLA has excellent properties such as high mechanical strength, ductility and good biocompatibility, and is easy to process. Among them, blow molding and thermoplastic are the most commonly used, with a wide range of applications and promising prospects.

Using corn starch and PBAT as the main raw materials, and glycerol as the main plasticizer, starch-filled PBAT film was made by extruder granulation and then blow molding. The plasticizing effects of different plasticizers in starch-filled PBAT materials were studied and compared.

The screw of the twin-screw extruder is a building block combination. The combination of the entire screw should be selected according to the specific formula, material characteristics, mixing requirements and operating conditions.

In general, the extrusion process experienced by the material in the twin-screw barrel generally includes: feeding, melting, melt conveying, mixing, homogenization, exhausting, metering, and the like.
