混炼焦烧特性
1.
The mixing scorch safety ( t s and Δ t ) of four kinds of rubber compounds (NR,SBR,BR and NBR) was measured using a Brabender torque rheometer in a wide temperature range (100~140 ℃) and rotor speed range (20~80 rpm),and compared to Mooney scorch safety ( t 5 and Δ t 30 ).
采用Brabender转矩流变仪 ,在混炼温度为 10 0~ 14 0℃和混炼转子转速为 2 0~ 80r·min- 1 的条件下测试了4个胶种 (NR ,SBR ,BR和NBR)的混炼焦烧特性 (ts 和Δt) ,并与门尼焦烧特性 (t5和Δt30 )进行比较 ,指出门尼焦烧不能真正地反映混炼胶在实际加工过程中的焦烧特性。
补充资料:捣固炼焦
扩大炼焦煤源的炼焦方法之一。利用专门的捣固机械,将装炉煤料捣固成煤饼,然后从炭化室的一侧推入。使装炉煤料的堆密度可以增大到0.95吨/米3以上(顶装焦炉煤料堆密度一般为 0.75吨/米3左右)。捣固炼焦,对采用以胶质层厚度在11~14毫米的气煤为主的煤料,效果比较显著。
