How to solve the sticking wall phenomenon of stainless steel reactor

1/10 2020 Reading (2727)

To avoid sticking to the stainless steel reactor, you must first understand the cause of the sticking.
Reasons for the sticking of the stainless steel reactor:
1. Temperature difference: The temperature difference between the temperature of the kettle wall and the cooling medium is too low or suddenly lowered, so that the temperature difference between the temperature of the kettle wall and the material is too large, resulting in contact with the glue sticky wall of the stainless steel reactor.
2. Reaction time and temperature of the reaction kettle: When the temperature of the reaction solution is lower than 80 ° C, if ammonia chloride is used as a catalyst, the pH value cannot be displayed due to the fast reaction speed of ammonia chloride. After the temperature rises, the pH value It decreases rapidly, the reaction speed is accelerated, and the polycondensation reaction is too intense, which causes gelation and sticky walls.
3. Reasons for the materials: For example, the sulfate content in urea is too high. When urea is added at the later stage of the resin polycondensation reaction, it is equivalent to adding a curing agent to promote rapid crosslinking of the resin into a network structure. At this time, stickiness will occur. Wall phenomenon.
4. During the production operation of the stainless steel reaction tank, it should be slowly pressurized and heated. When the temperature and pressure of the rubber production process indicators are unstable or fluctuated too much, the resin polycondensation reaction process is uneven, and it is easy to cause sticking walls.
Tips from the editor of Xiangpai Machinery: The stainless steel reaction kettle plays a great role in the reaction and mixing of many materials. Therefore, only the correct use of the reactor can avoid the phenomenon of sticky walls in the kettle and ensure the quality of production. And efficiency.
The inner and outer surfaces of the stainless steel reactor are mirror-polished and can be cleaned well in most production situations. Special conditions are treated specially. Sticking to the wall will still occur in the case of special materials, special production processes, and improper operation. The sticking wall of the stainless steel reaction kettle will affect the production quality and damage the kettle body. Therefore, you must master the use skills before you use it, so that the reactor can be used longer.
