Once this separation occurs, the raw material liquid being filled will immediately leak to the outside environment of the reaction kettle. This not only directly leads to the unnecessary waste of the raw material liquid, increases the production cost, but also in some special cases, when the raw material liquid has irritating odor, the leakage will quickly pollute the surrounding air environment, expose the operating personnel to the harmful gas atmosphere, cause damage to the respiratory system and health of the operating personnel; if the raw material liquid has corrosive property, the leaked liquid will also cause corrosion damage to the equipment and facilities, working site and the like around the reaction kettle, seriously affect the normal service life of the equipment and the safety of the working site, and also greatly increase the equipment maintenance cost and cleaning difficulty.
