Annular rubber synchronous belt this production process, the manufacturing process of belt artificially divided into several pieces, can't link up; Combined with the transmission belt specifications too much, production batch is small, frequent product changes, to the continuous of process equipment, automation has brought many difficulties, the production efficiency is very low. The current trend of the development of abroad, one is to research and implementation process of continuous production, improve the level of automatic control equipment, prompted greatly improve production efficiency, 2 it is to continue to expand use liquids such as polyurethane elastomer, radically simplify process, shorten the process, change the traditional way of rubber processing technology. Now, polyurethane liquid phase process in small and micro, has dominated, is optimistic outlook. Also, short fiber and rubber mixing is the belt in today's world the industry a big issue. How to make the uniform dispersion of short fiber in rubber, and solve the resulting rubber of high viscosity, resulting in decreased efficiency of phenomenon, need to have the new mixing method and the control mode. In addition, the fiber array orientation of short fiber and rubber is also another problem to be reckoned with, usually adopts the calender and orientation for the extruder glue out, according to the flow direction to take pills method, also not good zui. Non-woven fabrics, composite sheet is the direction of the development in the future. Information: annular rubber synchronous belt, ring rubber synchronous belt at http://www. lilainuo。 com
