PLA resin extrusion melt pump PBAT continuous screen changer

PLA/PBAT extrusion melt pump introduction

PLA/PBAT resin extrusion melt pump is mainly used for the steady pressurization and stable flow of PLA melt medium. It is used in conjunction with the extruder. PLA resin is also called polylactic acid. It is a polyester polymer obtained by polymerization of lactic acid as the main raw material. It is a new type of biodegradable material. PBAT is a thermoplastic biodegradable plastic. It is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has both good ductility and elongation at break, as well as Good heat resistance and impact performance; in addition, it also has excellent biodegradability, which is very active in the research of biodegradable plastics and one of the best degradable materials for market applications.

PLA/PBAT melt gear pump characteristics

1. The optimized flow channel design of PLA / PBAT extruded melt pump can avoid dead corners in the flow channel, reduce material residues and improve product quality.
2. The improved gear parameter design makes the output pressure more stable and the pulsation rate lower, which is suitable for precision extrusion.
3. Using high temperature alloy steel, good wear resistance and long life.
4. Adopt different sealing methods to adapt to a wide range of viscosity.
5. Appropriate installation methods can be provided according to different site conditions of customers, which is more flexible and practical.

PLA/PBAT automatic continuous screen changer

PLA/PBAT mesh belt automatic screen changer can automatically filter and process plastic, rubber, chemical fiber, melt glue and other adhesives on-line, automatically replace the filter, without stopping the production line, without interrupting the product, increasing production and energy saving, saving time and effort, No waste, small pressure fluctuations in the melt system, constant material flow, high product quality, stable and reliable performance, and are well received by users.

PLA/PBAT polymer screen changer advantage

1. This series of screen changer is composed of filter body, heating/cooling series, electric control system, etc.
2. No external force control is required, and its system control elements can automatically control the filtering time and the speed of the net.
3. Automatic and continuous replacement of the filter screen without any manual operation.
4. During the screen changing process, there is no fluctuation in material flow, no product deformation, and good quality stability.
5. No waste or waste is generated, and raw material consumption is low.
6. The length of the filter screen is 10~20m and can be customized for 2~6 months without interruption.

Horizontal installation method of PLA / PBAT extruded melt pump and screen changer

1. PLA / PBAT extruded melt gear pumps can be installed in a variety of ways. The input shaft of the pump can be arranged horizontally or vertically (upward and downward); the drive system generally includes: motor, reducer, universal Couplings, pump connectors, reducer connectors, etc. The complete set of equipment includes melt pump, inlet and outlet connectors, drive system, control system, etc. Customers can choose according to specific conditions.
