实验室反应釜减少损坏方式：

　　实验室反应釜之耐腐蚀性基于在玻璃衬里与介质接触后，造成一层硅氧掩护膜，此膜阻拦了介质对罐体的腐蚀。当搪玻璃层接触强碱液时，其外表不能造成硅氧掩护膜，致使碱液一直向玻璃层深部腐蚀，而强碱浓度越高，温度越高其被腐蚀的水平越大，沸腾状况的强碱溶液具备大的腐蚀才能。

　　实验室反应釜在实践状况中，因为消费并非运用一种实验室反应釜介质，多种酸在一起时因为“混酸效应”多数状况下多下降离子活度，加重实验室反应釜腐蚀水平。倡议用户在腐蚀水平不肯定的状况下亦与实验室反应釜消费厂家联络。

　　在实验室反应釜实用规模中，有一个很主要的问题，这就是对实验室反应釜装备对温度的实用性。不言而喻，实验室反应釜钢与玻璃层的热收缩系数不同，当装备温度急巨变更时，所发生过大的应力会招致爆瓷而破坏实验室反应釜装备。为防止实验室反应釜这种破坏咱们在介质实用规模内还应注重实验室反应釜装备的温差，即冷冲击110℃，热冲击120℃，所以在实验室反应釜装备加热与冷却的历程中应迟缓进行。

Laboratory reactor to reduce damage:

The corrosion resistance of a laboratory reaction vessel is based on the contact between the glass lining and the medium, resulting in a layer of silicon oxygen shield that prevents the medium from corrosion to the tank. When the enamel layer is in contact with alkali solution, the appearance can not be caused by the silica membrane cover, which has been to the deep layer of glass alkali and alkali corrosion, the higher the concentration, the higher the temperature the corrosion level increases, alkali solution boiling condition to have the largest corrosion.

Laboratory reactor in the practice situation, because the consumer is not using a laboratory reactor medium, various acids together because of the "mixed acid effect" most of multi ion activity decreased, increased the corrosion level in laboratory reactor. It is recommended that users contact the manufacturers of laboratory reaction tanks at the level of corrosion uncertainty.

There is a major problem in the practical scale of the laboratory reactor, which is the usefulness of the laboratory reactor for temperature. It goes without saying that the thermal shrinkage coefficient of the steel and glass layer in the laboratory reaction vessel is different. When the equipment temperature changes rapidly, the excessive stress will lead to explosion porcelain and destroy the laboratory reactor equipment. In order to prevent the destruction of the laboratory reactor we should pay attention to the temperature of reactor laboratory equipment in practical medium scale, namely cold shock and heat shock 110 C, 120 C, so in the process of laboratory reactor equipment heating and cooling should be slow to.
