Biodegradable Plastic Polymer Melt Gear Pump

Due to the introduction of the "plastic restriction order" and related environmental protection policies, traditional plastic products can no longer meet market needs. Degradable plastics PLA, PGA, PBAT, etc. have become popular products due to their good degradability. Therefore, the production capacity of degradable plastics has expanded rapidly in the past two years, and the corresponding demand for gear pumps for polymerization is also very large. The common specifications of large polymer melt gear pumps provided by Zhengzhou Batte are: 6000CC, 8500CC, 12000CC, which can meet the needs of most working conditions.

The biodegradable plastic melt pump is used in conjunction with the reaction kettle for the transportation and metering of PLA (polylactic acid) melt; the PLA kettle bottom pump is designed with a large suction flange, which can complete the transportation of polymer materials under vacuum reaction conditions. . The pressure and flow pulsation is small, and the near-linear output of the flow can be realized, which is easy to control. The PGA bottom pump has good self-priming performance and can be applied to the working condition where the inlet is vacuum (-0.05～-0.09MPa). PBAT polymer melt pump has precise structure, high precision and long service life.

Biodegradable melt pump installation method The PLA resin kettle bottom melt pump is generally installed at the lower part of the reactor and used as a feed pump, and the input shaft of the pump is arranged horizontally. Drive mode: motor + reducer + universal coupling. In the industries of degradable materials, such as PLA/PBAT/PGA, Batte has a successful domestic application performance of melt gear pumps for PBAT production units, has a deep understanding of the PBAT process, and has maintained a long-term relationship with many patent providers and engineering companies. Good cooperative relationship, can provide esterification - → prepolymer - → final polymerization - → viscosity increase the whole production line gear pump device solution, can provide users with selection guidance to provide from the original solution, esterification, prepolymerization, polymerization, dehydration. Solutions for the whole process such as volatility and viscosity increase. info@battemachinery.com
