一、前言随着低温技术的发展,为了贮存大块的皮肤、大容量的血液及其它生物组织的需要,设计制作了一台容量和口径都比较大、保冷性能好的低温容器。该容器不是采用传统的不锈钢制作,而是采用铝合金壳体和玻璃钢颈管粘接工艺、其保冷性能比用不锈钢制作的提高七倍左右。该容器不仪口径大、保冷性能好,而且重量轻、投资小、成本低,是一种能满足广泛 I. Introduction With the development of cryogenic technology, in order to store the needs of skin, large volume of blood and other biological tissues, a cryogenic container with large capacity and caliber is designed and manufactured with good cold insulation performance. The container is not made of traditional stainless steel, but the use of aluminum alloy shell and FRP neck bonding process, the cold-proof performance than stainless steel made by about seven times. The container is not the big caliber, cold performance, and light weight, small investment, low cost, is a wide range of
