         polyvinyl chloride (PVC) aging is non heavy. how to anti its aging, long its use lifespan formed is important issues. anti aging is anti polyvinyl chloride (PVC) film 永远不 aging, is improve/increase its anti-aging property can, long its use lifespan.

        宇宙间一切 material 质 运动都 is versus made 约, versus effect/influence. has make polyvinyl chloride (PVC) film aging factors, 也必然存 in anti aging measures. from polyvinyl chloride (PVC) plastics industrial production 以, through production and a large amount of experiment/testing, for improve/increase polyvinyl chloride (PVC) film low temperature resistance anti aging property can very more as, many solutions, combined formed many low temperature resistance anti aging stabilizer and increase agent, is improve/increase polyvinyl chloride (PVC) film low temperature resistance anti aging property can 创造 良 good conditions.

         polyvinyl chloride (PVC) film aging front 述, main/primary 取决于 polyvinyl chloride (PVC) resin 本身 组 formed, structure and add stabilizer, increase agent and other, meanwhile and processing and use outer conditions, hot, light, oxygen and water and other has 关. polymerization effect/influence resin structure and other factors, 本书不予 discussion. is improve/increase low temperature resistance anti aging property can need from 几方面人手:

        ① formulation design —— main/primary is additives selection, use amount, ratio;

        ② process 确定;

        ⑧ use, repair and tube/pipe and other, its in additives selection is important. is anti hot, light, oxygen and water for polyvinyl chloride (PVC) aging effect/influence, need add stabilizer, stabilizer types type very more, has heat stabilized agent, antioxidant, light stabilizer, combined agent and other. this additives property can, function mechanism same, therefore in selection upper, need understanding and various stabilizer, increase agent property can, use amount, function mechanism.
