Embodiment Construction

[0008] The preferred embodiments of the present invention will be described in detail below in conjunction with the present invention.

[0009] The specific process route of polyvinyl chloride suspension method is as follows:

[0010] 1. Polymerization The process of suspension polymerization is to first pump deionized water into the polymerization tank to start the agitator, and then add the dispersant solution, initiator and other additives into the polymerization tank in turn. Then, put steam and hot water into the jacket of the polymerization kettle, and when the temperature in the polymerization kettle rises to the polymerization temperature (50-58°C), change the cooling water to control the polymerization temperature not to exceed plus or minus 0.5°C of the specified temperature . When the conversion rate reaches 60-70%, self-acceleration phenomenon occurs, the reaction is accelerated, and the exothermic phenomenon is intense, so the amount of cooling water should be in...

Abstract

The invention discloses a PVC suspension production method. The method comprises a, polymerization, b, alkali treatment, c, resin drying, and d, dehydration and finishing. The method solves the problem that the existing polyvinyl chloride production method has high energy consumption and low quality of finished products.

Description

technical field [0001] The invention relates to a suspension production process, in particular to a polyvinyl chloride suspension production process, which belongs to the field of plastic production. Background technique [0002] With the acceleration of my country's urbanization process, facing the huge pressure of population, resources and environment, in order to ensure the sustainable development of the national economy, the Chinese government has increased investment in urban infrastructure year by year, and the construction of municipal public pipelines has been accelerating. The specifications are constantly enriched, the output is constantly increasing, and the quality is constantly improving, especially the development of plastic pipes is faster, which has become a hot spot for investment today. At present, in the field of pipe applications, plastic pipes are developing steadily, and have gradually replaced traditional cast iron pipes and cement pipes in water supply...
