在突然停电时,五合机制胶在黄化阶段出现坏料的可能性最大。这是因为五合机虽然停止了搅拌,但黄化反应并未终止,由于五合机内壁温度较低,靠近机壁的碱纤维素与CS_2接触困难,黄化反应进行不均匀,制出的胶粘度高,有细小纤维影响过滤。另外,还有严重的粘车现象。以往所采取的措 In the event of a power outage, Wuhechan gum is most likely to have bad material in the yellowing stage. This is because although the mixing machine was stopped, the yellowing reaction did not stop. Due to the lower temperature of the inner wall of the machine, the contact of alkali cellulose near the machine wall with CS2 was difficult and the yellowing reaction was not uniform. High viscosity, fine fibers affect the filter. In addition, there is a serious sticking phenomenon. Measures taken in the past
