The hot summer temperatures, need to use more and more ice cold preservation products, ice box purchase large quantities of products required temperature range has become an important work of the purchasing department in many enterprises, so many of my friends and the principle of ultra low temperature ice has relatively high interest, what is the principle of making ultra low temperature ice?
First we learn part of ultra cold packs, composed of high coolant and a double nylon composite film corrosion resistance to freezing and ultra low temperature ice mainly by an ultra low temperature phase transition temperature.
The production process of ultra low temperature ice is through a cold storage automatic filling machine according to quantitative ultra low temperature phase transition temperature, coolant is poured into the nylon composite membrane material and the plastic bag, the staff through the edge of the packaging bag is made of super low temperature sealing, ice bag.
The principle of ultra low temperature ice pack is to realize the constant temperature protection of low temperature articles by the operation principle of phase change so as not to destroy the low temperature articles because of the high temperature of the outside.http://www.gel-pack.net/
