引言为适应合成塑料采用复合工艺发展的需要,连续混炼装置已取得了新的进展。目前,各种类型的连续混炼挤压机名目繁多,可随意择取。然而,对复合工艺的方法及在塑性材料领域中的应用又提出了更新的要求,现已研制出混合和合金化的复合工艺,而且这一工艺已经沿用这种连续混炼装置用于连续反应过程。混合和合金化的过程需要高剪切和分散的专用设备,而且反应过程工艺强调连续分散。因此,这类设备必须具备以下各种功能:1)控制温度;2)在留置期间时间的控制,3)自动清洗;4)易于变更工序组合;5)
Introduction In order to meet the needs of the development of composite plastics using synthetic technology, continuous mixing device has made new progress. At present, various types of continuous mixing extruder variety, free to choose. However, there is renewed demand for a composite process method and its application in the field of plastic materials. A compounding and alloying compounding process has been developed, and this process has been used in such a continuous mixing apparatus for continuous reaction process. The mixing and alloying process requires specialized equipment for high shear and dispersion, and the reaction process emphasizes continuous dispersion. Therefore, such devices must have the following functions: 1) control of temperature; 2) control of time during stay; 3) automatic cleaning; 4) ease of change of process combination;
