不少人在操作实验室密炼机的时候,都不知道密炼机上顶栓的压力应该怎么设置才比较合理。下面，世研仪器来为你大家简单的介绍,。
对于密炼机来说，混炼不同的胶，不同的时间，不同的温度，压力是差不多的。
一、增加上顶栓对胶料的压力，能够提高胶料中的流体静压力，虽然不直接影响剪切应力，但是由于减少了密炼室内胶料的空隙，使得胶料与密炼室内壁，转子，上、下顶栓等之间，以及胶料内部各种物料之间更加迅速地互相接触和挤压，加速各种物料混入胶料中的讨程,从而缩短混炼时间，提高密炼机的功效。
二、增加下顶栓压力，使物料之间更加迅速地互相接触和挤压，并使物料之间接触面积增大,从而减少了胶料与密炼室内壁及胶料与转子表面的滑动，能间接的导致较高的剪切应力，加速分散过程，从而缩短混炼时间，提高了混炼胶质量。
最后，世研塑料挤出机厂家提醒大家，在调整上顶栓压力的同时还应注意东莞密炼机的混炼温度，同时注意修改现有的混炼工艺。
