The PU reactor in Hangzhou is easy to operate and maintain

Description :

　　The materials of reaction vessels generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel) alloys, and other composite materials. The reaction vessel can be made of stainless steel materials such as SUS304 and SUS316L. Blenders come in anchor, frame, paddle, turbine, scraper, and combination types. The rotating mechanism can use cycloidal pinwheel reducers, continuously variable speed reducers, or variable frequency speed reducers to meet the special reaction requirements of various materials. The sealing device can adopt sealing structures such as mechanical seals and packing seals. Heating and cooling can be achieved through structures such as jackets, half tubes, coils, and Miller plates. Heating methods include steam, electric heating, and thermal oil to meet the process requirements of different working environments such as acid resistance, high temperature resistance, wear resistance, and corrosion resistance. And it can be designed and manufactured according to the user's process requirements.

　　Attention to the use of reaction kettle

　　A reactor is a type of reaction equipment that must be operated carefully, otherwise it may be damaged due to various reasons, leading to production stoppage. There are many aspects to pay attention to when operating a reactor.

　　Firstly, it is necessary to strictly operate the reactor according to the rules and regulations.

　　Secondly, before operation, carefully check for any abnormalities. During normal operation, do not open the upper cover or touch the wiring terminals on the board to avoid electric shock; It is strictly prohibited to operate under pressure; During the nitrogen pressure test, carefully observe the changes in the pressure gauge. Once the test pressure is reached, immediately close the nitrogen valve switch; The heating rate should not be too fast, and the pressurization should also be carried out slowly, especially the stirring speed, which is only allowed to increase slowly.

　　Afterwards, when the kettle body is heated to a higher temperature, do not come into contact with the kettle body to avoid; After the experiment, the temperature should be lowered first. Do not cool quickly to prevent damage caused by excessive temperature and pressure differences. At the same time, it is necessary to unplug the power supply in a timely manner.

　　At the same time, attention should be paid to maintenance of the reaction kettle after use, so that the high-pressure kettle can have a better service life.

　　The broad understanding of a reactor is a container that contains physical or chemical reactions. By designing the structure and configuring the parameters of the container, the heating, evaporation, cooling, and low-speed mixing functions required by the process can be achieved.

　　When using a stainless steel reactor, the refrigerant inlet valve must be closed, the remaining refrigerant in the pot and jacket must be drained, and then the material must be input. The mixer should be started, and then the steam valve and electric power supply should be turned on. After reaching the desired temperature, the steam valve and electric power supply should be turned off first. After 2-3 minutes, the mixer should be turned off. After processing is completed, the remaining condensed water in the pot and jacket should be drained, and the sticky material should be washed away as soon as possible with warm water. Then, the inner wall of the container should be thoroughly cleaned with 40 ℃ -50 ℃ alkaline water, and rinsed with clean water. Especially when there is no material (heat absorbing medium) in the stainless steel reactor pot, the steam valve and electric power supply should not be turned on. Pay special attention to the use of steam pressure. Do not exceed the rated work pressure.
