The measurment of rheological properties by slit(capillary) die on extruder exhibits some obviousadvantages over other rheometers. A set of slit die isdesigned and made,and the theological data of LDPEat various screw are measured. The results show thatthe technique is of great importance to polymerprocessing.

与一般常用的流变仪相比,在挤出机上用狭缝或毛细管口模测试高聚物的流变性能有很多优点,例如可同时适合于测定材料的粘性和弹性、测试装置简单,并且测试过程与实际生产过程比较一致。本文作者自行设计加工了几套狭缝毛细管和流变口模,以LDPE为原料,在不同螺杆转速下用狭缝口模初步进行了流变性能测试,实验证明这种方法简单、可行,适合于在实际生产控制中应用。

In this paper the mechanical behaviour of the fluid at the exit of a slit die has been analysed theoretically based on the basic law of hydromechanics. The study indicates that the shear stress of the fluid cross section at the exit is the cause leading to fluid bend. The direction of exit bend angle was approached and the equation which is used to calculate bend angle was deduced. In the experiment two fluids of different rheological behaviour were coextruded side by side through a slit die. The...

In this paper the mechanical behaviour of the fluid at the exit of a slit die has been analysed theoretically based on the basic law of hydromechanics. The study indicates that the shear stress of the fluid cross section at the exit is the cause leading to fluid bend. The direction of exit bend angle was approached and the equation which is used to calculate bend angle was deduced. In the experiment two fluids of different rheological behaviour were coextruded side by side through a slit die. The magnitude and direction of bend angle was measured. Experimental results are corresponded with theoretical analysis.

本文从流体力学的基本定律出发,从理论上分析了流体在狭缝出口处的力学行为.研究表明,流体在出口横截面上的剪切应力是导致流体弯曲的根本原因;探讨了出口弯角的方向;导出了出口弯角的计算公式.实验采用流变性能不同的两种流体从狭缝模并列挤出,测定了弯角的大小和方向.实验结果与理论分析相一致.

This paper summarizes several structures of distribution flow system used widely in slit die in extruding simple melt plastics,and on the basis of rhecological theory and several actual supposes for coathanger manifold die and mold,presents a novel and quick approach to design the distribution flow system of coathanger manifold die and mold by the method of representative data.

本文概述了几种典型的挤出单一熔体的缝口模头的分配流道系统结构,并在流变学理论分析和对衣架型分配流道系统进行实际假设的基础上,采用特征数据法,对挤出单一熔体的衣架型缝口模头的分配流道(歧管)系统实现了计算机辅助设计,以生成最优化的衣架型缝口模头的分配流道系统。
