简述开炼机与密炼机区别

Time:2016-11-07   Hilts:407

在橡胶行业,炼胶时经常会用到开炼机、密炼机设备。开炼机与密炼机的区别有哪些呢?其特点有哪些呢?下面我们来分析一下。

开炼机与密炼机区别:

开炼机混炼量少,各种配合剂量好加,因为是开放式的,散热快,温度影响不是那么明显,如果温度过高了,可以停炼一段时间,让其冷却后再混炼;密炼机单次炼胶量是开炼机的数倍,混炼过程中需要严格控制温度变化,同时需要控制小料的添加次序。

再者由于密炼量较大,以前也考虑硫化最后通过开炼机加入,后来发现行不通,因为一车密炼机的料相当于几车的开炼机料量,无法混炼加硫,如果通过开炼机来加硫,则必须将密炼机的一车料分割几车开炼机的料来加,但是现实是这样不行的,因为每车密炼的料你是无法保证混炼均匀的,分割的胶料重新计算的组成 含量一般来说是不均匀的、不对的,添加的硫磺也将是不对的、不合理的。因此硫化也必须通过密炼过程加入,这时候温度的控制更加重要

开炼机与密炼机的区别在哪里?综合本文所述,最基本的区别就是工艺的不同。在炼胶时选择开炼机或密炼还是依据胶料的特性以及客户需要来选择。
