我国煤矿井下用低级别输送带主要采用整芯带 ,高级别 ( 1 40 0Ｓ以上 )则主要采用钢丝绳芯带。随着整芯带技术水平的提高 ,高级别阻燃整芯输送带也越来越普遍地被采用。本工作研制了适用于高级别阻燃整芯输送带的覆盖胶。1 胶料配方覆盖胶配方设计中要注意以下几点 :( 1 )胶料
China’s coal mine with low-grade conveyor belt mainly uses the whole core belt, high-level (more than 1 40 0S) is mainly used steel cord core belt. With the improvement of the whole core technology, the high grade flame retardant whole core conveyor belt is also more and more widely adopted. This work developed a suitable high-level flame retardant whole conveyor belt cover plastic. 1 plastic formula formula design covering plastic should pay attention to the following points: (1) rubber material
