AkzoNobel Introduces Safer Organic Peroxide System to U.S. PVC Market
阿克苏诺贝尔特种化学品公司将开始在美国生产聚氯乙烯(PVC)的首批乳液型有机过氧化物。乳液产品是用于制造聚氯乙烯(PVC)的溶剂型过氧化物的更安全替代品,聚氯乙烯是日常应用中使用的塑料,包括管道,门窗和家庭壁板。
“有机过氧化物经常在非常低的温度下分解,当不储存或处理不当时会导致燃烧,”Americas - Polymer Chemistry销售总监Rob van de Graaf说。“乳液含有水,大大降低了燃烧的可能性,并增加了运输,储存和处理的安全性。改进的安全特性还允许大容量储存和全自动化处理,降低手动操作事故的风险。
基于乳液的过氧化物还含有防冻剂,防止有时在基于溶剂的溶液中发生的冰晶形成,这可能影响引发剂向聚合反应的进料。这也改善了成品PVC产品的产品质量。
“欧洲的PVC生产商已经在使用我们的乳液型有机过氧化物,随着美国的推出,我们相信我们的客户将会获得同样的收益,我们有信心有机过氧化物乳液市场将继续增长,”Johan Landfors说。 ,负责高分子化学的执行委员会成员。
该公司的连续引发剂剂量(CiD)技术也使用基于乳液的过氧化物。使用CiD,PVC反应器中的产热量通过在聚合过程中加入过氧化物来控制。这优化了冷却能力,并将批量生产时间缩短了20%到40%,从而提高了总体生产能力。通过能够随时停止聚合反应,从而进一步提高PVC聚合安全性,从而防止失控反应。
