要获得质量好的混炼胶抖,必须经过充分的混炼,选用适宜的混炼机是非常重要的,控制加工温度是胶料在混炼机内混炼的关键。特别是白炭黑胶料的混炼必须控制其温度,所以,对混炼机进行降温就显得尤为重要。文中将新型加压式55L捏和机与老式的75L密炼机进行了降温对比试验,测定了整机及各个部位的降温幅度和导热率。 To get a good quality mix of rubber shaking, must be fully mixed, the selection of a suitable mixer is very important to control the processing temperature is the rubber compounding in the mixing machine key. In particular, the mixing of silica fumes must be controlled by the temperature, so it is important to cool the mixer. In this paper, a new type of pressurized 55L kneading machine and the old 75L mixer were compared in cooling test, measuring the whole machine and various parts of the cooling rate and thermal conductivity.
