Abstract
Description
Technical Field
[0001] The invention relates to the technical field of PVC heat stabilizer production, in particular to a reaction device used for the production and preparation of PVC heat stabilizer. Background Art
[0002] PVC heat stabilizer is an additive that can improve the thermal stability of polymers. It is mainly used for PVC (polyvinyl chloride) and other chlorine-containing polymers. Due to the poor thermal stability of polyvinyl chloride, it is easy to degrade, cross-link, discolor and age due to heat during processing, use and storage. Therefore, heat stabilizers are needed to extend its service life and protect the quality of products. PVC heat stabilizers can capture or chelate harmful metal chlorides or other harmful substances in polymers to prevent them from catalytic degradation of polymers, thereby achieving the purpose of stabilizing PVC.
[0003] The existing PVC heat stabilizer reproduction reaction is usually carried out in a reactor. However, the stirring and mixing in the reactor is usually carried out by a stirring blade driven by a motor, and the mixing effect is relatively general. In addition, the PVC heat stabilizer is prone to thermal decomposition due to high temperature, releasing HCl gas, which leads to severe degradation of PVC. If it is not controlled, this decomposition will be further aggravated, seriously affecting the quality and performance of PVC products. Therefore, temperature control is particularly important when producing PVC heat stabilizers. Summary of the invention

[0017] 3. The temperature sensor on the temperature measuring device is set on the inner wall of the reactor, so that the temperature in the reactor can be detected. When the temperature is too high, the cold water in the water tank is extracted by the water pump on the cooling device, and passed into the circulating water pipe through the water pipe.
