据《最新科技情报》介绍,日本航空公司研制成功可以代替冰的新型保冷材料,它比冰不容易溶化,保冷时间长。这种新型保冷材料是在合成树脂制的袋中,装入吸水树脂的粉沫制成,加水使它冻结后即可使用。合成树脂袋采用耐给与聚乙烯拼合而成,增强了它的强度。吸水树脂为丙烯酸酯(acrylicest-er)。每袋约加0.1升水。用飞机运送水产品多采用冰冷却,但冰易溶化,且有漏水等问题。上述新型保冷材料在25℃以下5小时以上不会溶化,可多次重复使用,重量较水轻30％,可大幅度降低运输成本。
According to “the latest scientific and technological intelligence,” introduced, Japan Airlines successfully developed a new type of cold to replace the ice material, which is not easy to dissolve than ice, cold for a long time. The new cold-proof material is made of synthetic resin bags, filled with absorbent resin powder, add water to freeze it can be used. Synthetic resin bags made of polyethylene and resistant to put together to enhance its strength. The water absorbing resin is acrylicest-er. About 0.1 liters of water per bag. Use of ice to transport aquatic products using ice-cooled, but the ice is easy to dissolve, and there is water leakage and other issues. The above-mentioned new cold-keeping material can not be melted for more than 5 hours under 25 DEG C and can be reused repeatedly with the weight being 30% lighter than that of water, which can greatly reduce the transportation cost.
