一机部武汉材料保护研究所研究成功的,由常州包装材料厂中试的新型防锈包装材料BF—7吹塑型气相防锈塑料薄膜和CF—4涂覆型气相防锈塑料薄膜、于1981年5月下旬在一机部机械科学研究院和外贸部中国包装进出口总公司联合主持的常州鉴定会上通过了鉴定。一致认为,这两种气相防锈塑料薄膜都对钢、铝及其合金有良好的防锈能力,CF—4气相防锈塑料薄膜还对钢及镀锌、镀镉钝化件有适应性,封存防锈期二年,其透明度、柔韧性、可焊性等主要理化性能达到美、日同类产品标准水平。气相防锈塑料薄膜的研制成功,填补了我国气相防锈包装材料的空白,为发展我国的防锈包装材料开辟了一条新的途径。
A machine research institute of Wuhan Institute of Materials successfully researched by the Changzhou Packaging Materials Factory Pilot new rust-proof packaging materials BF-7 blow-type VCI plastic film and CF-4 coated VCI plastic film, at In late May 1981 in a machine-made Institute of Machinery Science and Technology and the Ministry of Foreign Trade China Packaging Import and Export Corporation jointly chaired the Changzhou appraisal passed. Unanimously, both of these vapor-phase anti-rust plastic films have good antirust ability to steel, aluminum and their alloys, CF-4 vapor phase anti-rust plastic film also has adaptability to steel and galvanized, Anti-rust storage period of two years, its transparency, flexibility, solderability and other major physical and chemical properties to the United States, Japan standard level of similar products. The successful development of vapor-phase anti-rust plastic film has filled the blank of vapor-proof packaging materials in our country and opened up a new way for the development of rust-proof packaging materials in our country.
