现在常用镀银或镀铝的玻璃反射镜来制造太阳能聚光器,然而玻璃既笨重易碎,供应又比较紧张。工业发达的一些国家也有用阳极氧化铝来作反射镜的,但这种反射镜价格昂贵,难以大规模推广。因此,研制一种比较理想的新型反光材料,便成了一项十分迫切的工作。在有关单位共同努力下,上海研制成一种胶带式反光材料(全称胶带式聚酯薄膜真空镀铝反光材料),在新型反光材料的研制方面迈出了可喜的一步。这种反光材料以聚酯薄膜为底材(厚0.020—0.025毫米),真空涂铝层作反光层(1公斤铝可蒸涂1000平方米),有机硅树酯作保护层,外面还涂有硅
Solar reflectors are now commonly made of silvered or aluminized glass mirrors, however, the glass is both bulky and fragile and the supply is relatively tight. Some developed countries also use anodized aluminum as reflector, but this reflector is expensive and difficult to promote on a large scale. Therefore, the development of a more ideal new reflective material, it has become a very urgent task. In the joint efforts of relevant units, Shanghai developed into a tape-type reflective material (full name tape-type polyester film vacuum aluminum reflective material), in the development of new reflective materials has taken a gratifying step. The reflective material to the polyester film as the substrate (thickness 0.020-0.025 mm), vacuum coating aluminum layer as a reflective layer (1 kg of aluminum can be cast 1000 square meters), silicone resin as a protective layer, the outside is also coated silicon
