　　反应釜使用注意
　　反应釜是一种反应设备，在操作的时候一定要注意，否则会因为很多原因造成损坏，导致生产被迫停止。反应釜的操作要注意很多方面。
　　首先，一定要严格的按照规章制度去操作反应釜。
　　其次，在操作前，应仔细检查有无异状，在正常运行中，不得打开上盖和触及板上之接线端子，以免触电；严禁带压操作；用氮气试压的过程中，仔细观察压力表的变化，达到试压压力，立即关闭氮气阀门开关；升温速度不宜太快，加压亦应缓慢进行，尤其是搅拌速度，只允许缓慢升速。
　　，釜体加热到较高温度时，不要和釜体接触，以免烫伤；实验完应该先降温。不得速冷，以防过大的温差压力造成损坏。同时要及时的拔掉电源。
　　同时反应釜使用后要注意去保养，这样高压釜才能有更好的使用寿命。

　　Reactors are widely used in fields such as petroleum,chemical,rubber,pesticides,dyes,medicine,and food.They are pressure vessels used to complete processes such as vulcanization,nitrification,hydrogenation,alkylation,polymerization,and condensation,such as reactors,reaction pots,decomposition pots,polymerization pots,etc;Materials generally include carbon manganese steel,stainless steel,zirconium,nickel based(Hastelloy,Monel,Inconel)alloys,and other composite materials.
　　Classification of reaction vessels
