双层玻璃反应釜采用的是高硼硅玻璃，具耐高温、耐腐蚀、硬度高、低膨胀率和透光率高等特点，相比起普通的玻璃更像是性能特殊的塑料制品。但是我们在对双层玻璃反应釜的操作过程中，如果使用不恰当也会对双层玻璃反应釜造成不可避免的损伤，严重情况下甚至会产生破裂的现象。接下来就带大家了解下产生这种情况的原因，以及如何有效的避免这种情况的发生。

 

 

   当双层玻璃反应釜在进行实验的时候，当实验温度超过规定使用温度时物料的剧烈反应会产生大量的气体，气体使反应釜内气压剧增对双层玻璃反应釜造成损伤。所以我们在操作过程中应该注意观察物料的变化，或者对双层玻璃反应釜增加泄压装置，出现不正常情况应该立即停止避免出现损伤。

   双层玻璃反应釜的夹层的压力过高时，也会导致反应釜釜体受损或破裂。尤其是在使用高压蒸汽作为温度媒介时，需要经过减压后才能正常使用，但是减压阀一旦出现问题失效会导致夹层超压，从而导致釜体因压力过大产生破裂等现象。建议增加一个加压阀起到双保险的作用。
