摘要
通过塑化成型试验,找出双螺杆机塑化成型的工艺规律,用正交试验确定工艺参数。用极差分析方法分析了溶剂比、模具形式、螺杆组合方式、模具水温、螺杆水温对产品密度、机头压力和扭矩的影响。结果表明,模具形式对产品密度影响最大,溶剂比对机头压力影响最大,螺杆组合方式对主机扭矩影响最为显著。分析了螺杆转速对机头压力和加料频率对扭矩的作用关系,为双螺杆技术在连续化、自动化发射药生产线中的工程化应用提供了依据。
Through plasticization and molding experiments, the technology rule of plasticization and molding of twin-screw machine is found and the main technology parameters are determined. An orthogonal experiment method is adopted to determine the technology parameter. The effects of solvent percentage, die form, screw- combining mode, water temperature in die and screw on product density, die pressure and torque were analyzed by the range analysis method. The results show that the solvent percentage has the most effect on die pressure. The die form has the most effect on product density and screw-combining mode has the most effect on torque. The effects of screw rotating speed on die pressure, and of adding frequency on torque are also analyzed. The results obtained offer a technology foundation and basis on the engineering application of the twin-screw technology in continuous and automatical propellant production line.
