Tianzhou-1 cargo spacecraft was lunched in China successfully yesterday. Tianzhou-1 cargo spacecraft carrying the low temperature locker is used for materials preservation, its with extremely tough targets for the performance of heat insulation materials, both thermal insulation, and frivolous, this is what a traditional insulation material cannot be carried out. Aluminum foil packaging is used to produce "VIP" material for Tianzhou-1 cargo spacecraft.
Because of the strict requirement of heat insulation performance, the mature aerogel insulation materials is necessary, however, there is a big gap between the thermal conductivity and asked performance index, the aerogel cannot satisfy the application requirements. After several rounds of testing and verification, "vacuum" of aerogel material is produced, using aluminum foil membrane coated aerogel resistance, to carry on the process of pumping air into vacuum state, as a result, "vacuum insulation board" based on the aerogel materials was born, and it can effectively prevent air convection caused by heat transfer, make its coefficient of thermal conductivity is greatly reduced to original aerogel material, and heat insulation performance improved nearly doubled, at the same time it had good capability and puncture resistance. The aerogel products with aluminum foil packaging finally reached the strict technical requirements, it is made into the protection coat of low temperature locker of Tianzhou-1 cargo spacecraft. The outstanding strong points of aluminum foil make contribution on the technical construction project again. On the other side, aluminum foil are widely used in daily life, you can baking with it, fish, cake or other food you like. Packaging industry has been one of important aspect of aluminum foil usage, and develops very fast, in 2005 the world packaging container with aluminum foil is about 21 % of total global aluminum production. Aluminum coil packaging products include household packaging materials, flexible packaging, food containers, caps, cans, food cans, hose and so on.
