干冰是什么?干冰是固体二氧化碳,凝聚成一种无色液体的压力6250.5498 kPa,然后迅速蒸发在低压形成干冰。干冰的用途是什么?干冰中使用广泛的应用,如人工降雨,保存新鲜食物,灭火,冷冻疗法,保存血浆和医疗药物在医院,等。有许多应用在食品、卫生、工业和餐饮。我需要什么样的储存条件为干冰吗?因为干冰的凝固温度是-78.5,它开始挥发时达到-78度,很容易挥发和升华成无毒,无味,600 - 800倍的固体体积气体二氧化碳,所以干冰不能存储在完全密封的体积的容器,如塑料瓶、干冰和液体混合容易爆炸,因此干冰必须存储在一个特殊的冰箱。干冰在零下60度和零下40度超低温冰箱可以短期存储5 - 10天,但由于温度大于解散干冰,干冰挥发,天然气的生产,所以只适合短期存储少量,放置在- 80度低于超低温冰箱可以长期储存。干冰必须存储和正确使用,防止不必要的伤害造成的错误的干冰处理。干冰,制冷剂冷链运输,因此被推到聚光灯下由于-70°C的极端低温运输要求辉瑞/ BioNTech疫苗。大量的非洲医疗机构选择使用超低温冰箱存储干冰,在-78°C开始蒸发,所以他们不得不选择较低的冰柜的温度。 The DW-HW138 and DW-HW328 ultra-low temperature freezers developed by Meling Biomedical are very suitable for storing dry ice, and the temperature of minus 86 degrees makes the dry ice not easy to volatilize. The ultra-low temperature freezer is slow to dissipate cold when opening the door, and the cover is sealed and pressed and sunk with good insulation and cooling effect. Meling biolmedical -86 ℃ ultra-low temperature freezer DW-HW138 has a high-precision microcomputer temperature control system, temperature control accuracy of 0.1 ℃; 14 kinds of sound and light alarm system (high and low temperature alarm, sensor failure alarm, high ring temperature alarm, open the door alarm, voltage abnormalities, power failure alarm, condenser dirty alarm, battery power low alarm, system failure, etc.), items stored more safely; comes with USB temperature recorder, recorder and controller work with long time backup battery; stainless steel inside, painted steel plate outside, 6 units of casters for easy handling. The top door has key ...
