特点及用途

SJSZ系列锥形双螺杆挤出机，配以相应的模具和辅机，可将各种热塑性塑料特别是硬聚氯乙烯粉料直接挤出成管、板、片、膜及异型材等，也可完成对各种塑料的改性及粉料造粒过程，本机采用交流电机，可控无级调速，设有过载保护和故障报警，螺杆芯部油循环，机筒油冷却，并装有真空排气装置和定量喂料装置。

本机主要供挤出软、硬聚氯乙烯、聚乙烯等热塑性塑料之用，它与相应的辅机（包括成型机头）配合，可加工多种塑料制品，如膜、管、板、丝、带、电缆绝缘层及中空制品等，亦可用于造粒。本机设计先进，产量高，塑化好，能耗低，采用硬齿面齿轮传动，具有噪音低，运转平稳，承载力大，寿命长等特点。

Features and application

The series extruders with appropriate die-mould and auxiliary machine can directly convert thermoplastic especial PVC powder into pipe,plate,sheet.film and profile,and also provide function of modifying and pelleting.The extruders are derived by A.C motor with a thruster to steepless regulate.It is also equipped with the over-load protection and stoppage alarming system.The screw's core and the outside of barrel is cooled by circulation of oil,it includes vacuum venting and forced feeding.

This set is advanced in design,high in output,good in plasticization and low in energy consumption.The involute gear driving is characterized by low noise,stable working,big bearing capacity and long service life.This set can be used for extruding themo-plastics like soft or hard polyvinyl chlorid (PVC) and polystyrene(PE).Coordinated with the approptiate auxiliary machine (including the head of former),it can produce many kinds plastic products such as film,pipe,board,braid,beit as well as granule.
