As summer approaches, the temperature gradually increases, and more and more products are required to use ice packs for cryopreservation. The ice pack ice box that requires a large number of product-purchasing temperature zones has become an important task for most companies' purchasing departments. Therefore, many friends are very cold. The principle of ice bag production has a relatively high interest. What is the production principle of the ultra-low temperature ice pack?
First of all, we first understand the components of the ultra-low temperature ice pack. The ultra-low temperature ice pack consists of an ultra-low temperature transition temperature high-performance coolant and a corrosion- and freeze-resistant double-layer nylon composite membrane.
The production process of the ultra-low temperature ice pack is based on the quantitative analysis of the ultra-low temperature phase change temperature cryogenic agent developed by Nanchuan Chuanhang into a plastic bag processed from a nylon composite film material by a fully automatic cold accumulation agent filling machine. A staff from Nanbeichuan line sealed the bags through the edge banding machine to complete the production of ultra-low temperature ice bags.
The principle of the ultra-low temperature ice pack is to realize the constant temperature protection of the low temperature articles through the working principle of the phase change, so as not to allow the low temperature articles to be destroyed due to the high outside temperature.
