摘要： A polyolefin composition for electrical insulation which comprises polyolefin or crosslinked polyolefin and a small quantity of high-molecular weight polyethylene glycol. This composition is far less vulnerable to the deterioration that occurs as dendroid voids when employed as an electrical insulation of high-tension power cables which are operated under water. The polyethylene glycol has more than 44 carbon atoms and is used in an amount from 0.3 to 10 wt % based on polyolefin.

摘要： The purpose of the present invention is to provide a container sterilization method, washing method, and system which retain food hygiene manufacturing standards and a required production line speed, as well as reducing the amount of treatment fluids used such as pharmaceutical fluid, hot water and aseptic water. The container sterilization method and washing method of the present invention is a method in which a container is sterilized/washed using a treatment fluid, and the sterilization step and/or washing step are divided into at least two parts. By storing and pumping upwards the treatment fluid supplied from one part of the divided sterilization or washing step after use, the treatment fluid can be supplied in series to the other part of the same divided sterilization or washing step.
摘要翻译：本发明的目的是提供一种保持食品卫生制造标准和所需生产线速度的容器灭菌方法，洗涤方法和系统，以及减少使用的处理流体的量，例如药液，热水和无菌水。本发明的容器灭菌方法和洗涤方法是使用处理液对容器进行消毒/洗涤的方法，并且将灭菌步骤和/或洗涤步骤分成至少两部分。通过将使用后的分割灭菌或洗涤步骤的一部分供给的处理流体向上储存并向上抽吸，可以将处理流体串联供应到相同的分开的灭菌或洗涤步骤的另一部分。
