Study On The Technology Of The Injection Macromolecule Rubber

Rubber products have played a important role in the national economy and the construction of national defence. It is an essential material in the instrument and apparatus industry, the chemical industry, the automobile industry, the architecture industry, the mechanical industry, the war industry and the spaceflight industry. But the under-developed technology of the rubber confectioning has been an obstacle to the rubber application. The reason is that the main method of the rubber confectioning is the press mold method, which is the common way of the thermoset rubber. There are a lot of shortcoming about this means of confectioning such as the complex handle craft, the long confectioning period, the low produce efficiency, the easy destroyed mould, the instability of the quality and the physical force of handwork, etc.This topic focus on the injection confectioning of the rubber products in order to avoid the shortcoming of the press mold method. There are contents of three aspects, that is injection rubber, injection machine and injection mould. And these are the three elements about the confectioning of the thermoset macromolecule material. Because we can use the injection mould of the thermoplastic for reference, we would not study on it. The key problem of studying on the injection rubber is how to modify the injection rubber to obtain appropriate viscosity liquid in order to avoid the over vulcanization and burn in high temperature. And the mechanical capability of the rubber would not be weakened.The injection machine affects the injection process, and it was incarnated by the injection processing parameter. So the distributing of temperature and pressure in the injection processing will be one of the main contents in studying. Furthermore, the design of temperature surveillance and control would affect the injection processing seriously, it would also be studied in this paper.Otherwise, this paper will discuss the applied possibility of the Expert system which is comprehensively used in the other field. This would be helpful to the future development.
