液态二氧化碳可彻底清洗硅橡胶

与传统的硅橡胶清洗技术相比,冷洗技术可缩短75%的处理时间,降低35%的成本。

Nanon a/s公司(丹麦, Brndby; www.nanon.dk)开发了一种液态二氧化碳处理技术,可去除硅橡胶中的挥发性残留物,并且不到1小时即可杀死致病菌。据该公司介绍,传统固化后处理技术需要在200℃的烤箱内处理4小时,而这种冷洗技术可将处理时间缩短75%,同时最多可降低35%的成本。

Nanon公司业务开发部副总裁Thomas Christensen先生说: 该技术简化了硅橡胶在医疗器械中的应用处理,硅橡胶既可用于与皮肤接触的器械,也可用于植入体内的器械。 许多产品都将从该技术中获益,包括:硅树脂植入物、导管、引流管以及婴儿奶瓶的奶嘴。

这种冷固化技术利用加压液态二氧化碳对硅橡胶进行45分钟的清洗。液态二氧化碳可渗入材料中,并溶解其中的挥发性残留物。扩散结束后,材料内游离硅油等物质的含量可降低到0.1%至0.3%,远远低于EN14350-2的规定(0.5%)。硅油过多可造成污染,手术时还会危害病人的健康。

由于部件的处理均在低温下进行,因此,可避免烤箱处理过程中出现的裂隙弥合等问题。冷固化可确保硅橡胶部件上的小孔在处理期间及处理后均保持开放。

而且,这种新技术十分环保,整个过程均在闭环体系内进行,避免了游离硅油和硅尘的排放。二氧化碳可循环使用,不会增加温室效应。

该公司提供硅树脂产品的内部灭菌服务,对于购买冷固化设备的客户,公司还提供产品维修和免费培训。
