Title
(EN) Container blowing method
(ZH) 一种容器吹制方法
Abstract
(EN) The invention discloses a container blowing method. The container blowing method comprises the following steps of: (1) stretching a stretching rod into a bottle blank in a mold, stretching the bottleblank, and pre-blowing the bottle blank through low-pressure gas; (2) blowing the bottle blank into a bottle body through high-pressure gas; and at least one of the low-pressure gas and the high-pressure gas being a gas which can be ionized into plasma particles; and (3) ionizing the gas in the blow-molded bottle body, so that the plasma particles generated in the bottle body being deposited on the inner wall of the bottle body to form a coating. According to the container blowing method, equipment for coating after bottle body forming is omitted, and the cost is relatively low; the bottle body and the coating are formed at a time, so that the pollution risk increased by secondary processing is avoided; and the prepared bottle body has good light-blocking, oxygen-blocking and permeation-blocking properties, and can be used for filling beer and milk.
(ZH) 本发明公开了一种容器吹制方法,包括以下步骤:(1)将拉伸杆伸入处于模具中的瓶坯中,对瓶坯进行拉伸,同时通过低压气对瓶坯进行预吹;(2)通过高压气将瓶坯吹制成瓶体;低压气和高压气中的至少一种为可以被电离成等离子颗粒的气体;(3)对吹制成型的瓶体中的气体进行电离,使瓶体中生成的等离子颗粒沉积在瓶体内壁并形成一层涂层。本发明一种容器吹制方法,节省了瓶体成型后再行涂层的设备,成本相对较低;瓶体和涂层一次成型,避免了二次加工增加的污染风险;制得的瓶体具有良好的阻光、阻氧、阻透性性能,能够用于啤酒和牛奶的灌装。
