Due to the PET bottle which are applied for the special requirement of bear packing, so this paper briefly described the obstructing technology of PET and the relative research progress, mainly included surface coating technique, co-compounding or copolymer、oxygen clean up agent、multi- layer complex and nano technology.
由于PET(聚对苯二甲酸乙二醇酯)瓶应用于啤酒包装的特殊要求,本文对PET的阻隔技术及相关研究进展进行了简述,主要包括表面涂层技术(高阻隔氧化硅、无定型碳沉积技术、环氧胺技术等)、共混或共聚、氧清除剂、多层复合和纳米技术。
Surface coating is one of effective methods for preparing carbon molecular sieve membrane (CMSM ).
表面涂层法是制备分子筛炭膜的有效方法、以酚醛树脂的乙醇溶液作为涂层液对炭膜基板进行处理，制得适合H2/CO2分离的分子筛炭膜。
The surface coating techniques,which modify the surface components and structure of materials and their articles and thus yield surface coatings of good performance,are widely used in industries.
表面涂层技术能够改变材料及其制件表面成分和组织结构,获得性能优异的表面薄层,因而广泛应用于各行业。
The flexural properties and fracture toughness of several CVI-SiC/SiC composites with various fiber/matrix interlayers and SiC nanowires were investigated comparatively.
研究表明:界面涂层对SiC/SiC的力学性能至关重要,120nm厚的碳界面涂层使材料的强度与韧性都增加一倍;在用140nm厚的SiC层将该碳层分为更薄的两层,形成C/SiC/C多层界面涂层时,材料的强度没有明显的变化,而断裂韧性则略有提高。
