为什么干冰块放久了会变小或者直接消失？干冰质量不好吗？答案是否定的。事实上，您的干冰储存方式并不正确。干冰的挥发性极强，如果储存不当，干冰的消耗量会很大。作为专业的干冰制造商，我们舒利机械将为您提供一些有用的技巧，以更好地保存干冰产品。
干冰粒或干冰块的保存并不困难。真正的难点是如何降低干冰的损耗率，延长干冰产品的实用期限。这是很多干冰用户和干冰生产商最关心的问题，因为只有干冰保存完好才能减少损失，节省成本。
What can be done to make dry ice last longer?
The temperature of dry ice is minus 78 degrees Celsius, so if you want dry ice to last longer, you must first have a low-temperature environment, otherwise, it will be difficult to guarantee the storage time of dry ice. The dry ice preservation effect of ultra-low temperature refrigerator is very good, and the lower the temperature, the better the preservation effect of dry ice, the longer its service life. However, for most dry ice users and dry ice manufacturers, the cost of buying an ultra-low temperature refrigerator is too high and it is not practical. Therefore, it is ideal to use a special dry ice heat preservation box to store and transport dry ice products.
Environmental factors have a great impact on the storage of dry ice
The change in temperature in the environment has the greatest impact on the preservation of dry ice blocks and dry ice pellets. In the process of dry ice production, a lot of dry ice is wasted, because there is no dry ice incubator with good insulation effect and the correct operation method. We need to place the dry ice heat preservation box and dry ice in a cool, dry and well-ventilated area. After taking dry ice pellets from the dry ice box, the lid should be pressed immediately to prevent temperature loss and excessive dry ice evaporation.
Pay attention to the dry ice use process
During the use of dry ice, care should also be taken to reduce the loss of dry ice. Dry ice is easy to sublimate, and the smaller the volume of dry ice, the faster it will lose. Therefore, during the use, try not to cut the dry ice blocks several times. In particular, granules or powdery dry ice with a small diameter should be packaged in a package and taken out of the incubator when use.
Dry ice can not be stored in a sealed container
干冰极易挥发，会升华为无毒、无味，面积比固体二氧化碳大1000倍，所以干冰不能存放在密封良好、体积小的盒子里，有爆炸的危险。为了使干冰蒸发的气体自然释放出来，培养箱必须放置在空气流通良好的地方。
