Free energy-efficient twin-screw dry PET sheet extrusion machine after several years of efforts, the Nanjing Bo company successfully developed for PET sheet production of special twin-screw extrusion unit, the first unit has been set for continuous operation in the Guangdong High Fidelity Over five years, and achieved the desired effect, which is to highlight the advantages: ◆ eliminates the traditional pre-crystallization processes and raw materials drying process, significantly reducing energy consumption and costs dry; ◆ for PET water sensitivity characteristics, innovative research and development of efficient energy consumption online devolatilization technology to the water, and Bo super torque from the twin-screw technology and unique design combines a host, so the impact of PET water sensitivity and viscosity drop was the ideal control, in order to ensure and improve product performance quality to provide a solid technical support ; ◆ shorten simplify the process, can be used directly or authentic material crushing all kinds of PET material (such as APET, PETG, GAG, etc.), significantly improve production efficiency; ◆ for recycled materials form dimensionally unstable features, while supporting the development of a dedicated double-precision closed-loop control technique weightlessness dosing system and extrusion flow, can be adapted to different types of raw materials change shape, achieve high precision extrusion; ◆ can be provided on a single-layer sheet unit or two-unit composite sheet extrusion (GAG); ◆ can provide a complete production line of new processes, upgrading service is also available on the traditional single-screw production line.
