我厂使用数量较多的皮带溜槽,过去都是用热硫化胶接法粘接皮带和皮带挡边。由于硫化胶接工艺需加热升温和加压,经硫化反应,使生橡胶变成硫化橡胶才能胶按皮带,粘接工艺复杂,不经济,又不能成批生产,给生产带来较大影响。因此,自1972年起我们采用冷接工艺代替了上述工艺,十一年 I plant a larger number of belt chute, the past are bonded with hot vulcanized rubber belt and belt ribs. As the vulcanization bonding process needs to heat up and pressurize, the vulcanization reaction makes the raw rubber turn into vulcanized rubber to press the belt, the bonding process is complex, uneconomical, and can not be mass-produced, bringing great impact on the production. Therefore, since 1972 we have adopted the cold-bonding process instead of the above process, eleven years
