Abstract

The invention discloses a reaction system and method for intermittent production of chlorinated polyvinyl chloride. The reaction system mainly comprises a liquid chlorine vaporizer, a chlorine buffer tank, an activation reactor and a chlorination reactor, wherein the chlorine buffer tank is connected between the liquid chlorine vaporizer and the chlorination reactor, and the activation reactor is connected to the chlorination reactor. The reaction system disclosed by the invention is suitable for gas-solid phase chlorination reaction of polyvinyl chloride and other powder, can be singly used as a chlorination reaction system, can be used together with other chlorination systems, and has very good using flexibility. The reaction system and method for the intermittent production of chlorinated polyvinyl chloride are low in cost, high in product quality, easy in operation control and high in energy source utilization ratio, reduce the production cost, and can improve the chlorine content in chlorinated polyvinyl chloride to be more than 65%.

Description

technical field

[0001] The invention belongs to the field of industrial production of chlorinated high polymers, and relates to a system and method for intermittently producing chlorinated polyvinyl chloride. Background technique

[0002] Chlorinated polyvinyl chloride (CPVC) is a new type of engineering plastic obtained by chlorinating and modifying polyvinyl chloride (PVC) resin. After the PVC resin is chlorinated, the irregularity of the molecular chain arrangement increases and the polarity increases, which increases the solubility and chemical stability of the resin, thereby improving the heat resistance of the material and resistance to acids, alkalis, salts, oxidants, etc. corrosion performance. The mechanical properties of the heat distortion temperature of the resin are improved, the chlorine content is increased from 56.7% to 61-69%, the Vicat softening temperature is increased from 72-82°C to 90-125°C, the maximum service temperature can reach 110°C, and the long...
