Shanghai Daoqin Plastics Co., Ltd.

large more industrial has machine material, is also is combined formed, easy oxidation reaction, plastics, fiber, 橡胶, viscous agent, material 油, lubricated 油, food and material and other, and oxygen gas reaction, material and oxygen gas reaction rear 会失 原 has has property 质. 例如, if polymer/macromolecule material oxidation, 就会发生 aging, its surface viscous, color, cracking, polymer/macromolecule material 失 原 has use value. oxidation generate 沉淀, machine gas or tube/pipe, 导致发动 machine as positive 常. is 试图抑 made and anti upper oxidation phenomenon 发生, in 不改变现 has production process front lower, to types has 效便捷 methods, add resistant oxidation agent. in meet/satisfy polymer processing application requirements meanwhile, due to environmental protection and safety regulations day 益严格, in recent years antioxidant development has new toward and features.

1. reaction property resistant oxidation agent

resistant oxidation agent remove by 挥发消 consumption outer, in light hot function lower also 会变质 or and chemical material 质发生 reaction, in product use process in 迁移并 by solvent agent 萃取, reduce resistant oxidation agent can. therefore, 人们希望 development types property stabilizer, reaction property antioxidant, it can and mono polymerization, formed is polymer separation, solution antioxidant 挥发, 萃取, and other defect.

2. antioxidant polymer/macromolecule amount 化

持久 property and high property is amount stabilizer comprehensive property can 两 方面. molecular weight increase has decrease/reduce product in 挥发, and and other loss 失, meanwhile decrease/reduce product and and other issues. is, molecular weight is large good. due to oxidation main/primary in product surface, surface resistant oxidation agent consumption rear, product in resistant oxidation agent can and 时迁移 to surface formed is its has property key/critical, therefore resistant oxidation agent versus for separation quality usually in 1500 below/following.

3.无尘 and specialized resistant oxidation agent

large more resistant oxidation agent is powder 末状, 随 人们 for as ring requirements improve/increase, pellets resistant oxidation agent 开始出现, not only improvement 劳动者 工 as ring 境, make can 够准确测 amount resistant oxidation agent use amount. meanwhile, resistant oxidation agent in polymer in distribution more add uniform, has improve/increase product overall stability property.

4. composite/compounding resistant oxidation agent

resistant oxidation composite/compounding product tool has development cycle short, good, comprehensive property can good, multiple additives function separation 发挥, use use and other features.
