Abstract
The invention discloses an ice bag at low temperatures ranging from -19 DEG C to -26 DEG C. The ice bag comprises, by weight, 2-3 parts of polyvinyl alcohol, 1-2 parts of CMC cellulose or slow-release agents, 40 parts of ethylene glycol, 55 parts of pure water and 0.25-0.5 part of triethanolamine. By means of the low-temperature ice bag, the cold accumulation effect of vaccine at low temperatures ranging from -19 DEG C to -26 DEG C in cold chain transportation process can be achieved, and refrigerated transportation of the vaccine at the low temperatures can be achieved; two thirds of transportation cost can be saved through the ice bag and cold chain packages, the freezing point of the ice bag is -22.5 DEG C, and a storage solution is provided for the vaccine with requirements for temperatures ranging from -19 DEG C to -26 DEG C.
Description
Technical field
The present invention relates to a kind of ice bag, be specifically related to a kind of-19 ℃ to-26 ℃ of low temperature ice bags.
Background technology
Ice bag is in the market all to take the ice bag that zero degree is ice bag point as freezing point or subzero, due to the uncontrollable ice bag temperature of common ice bag, therefore in a lot of occasions, can not use, in vaccine transportation, very strict to the requirement of temperature, need the strict temperature of controlling, at this moment common ice bag is just helpless.
Summary of the invention
The object of the present invention is to provide and a kind ofly temperature can be controlled to-19 ℃ to-26 ℃ of low temperature ice bags.
The present invention is achieved in that
A kind of-19 ℃ are to-26 ℃ of low temperature ice bags, in described ice bag, composition is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, ethylene glycol 40 weight portions, pure water 55 weight portions, triethanolamine 0.25-0.5 weight portion.
The present invention also provides described-19 ℃ of preparation methods to-26 ℃ of low temperature ice bags, be specially: first by polyvinyl alcohol and pure water Hybrid Heating, after making it cooling, again with CMC cellulose, triethanolamine mix and blend, until product, become after paste, finally add ethylene glycol, stir and prepare composition in ice bag, then adopt conventional method to prepare ice bag.
The present invention can solve low temperature vaccine cold-storage effect in cold chain transportation process of-19 ℃ to-26 ℃, overcome the low temperature vaccine of refrigeration transportation, with this ice bag and cold chain, pack the cost of transportation that can save 2/3rds, its freezing point is-22.5 ℃, can at the vaccine of-19 ℃ to-26 ℃, provide storage solution for temperature requirement.
Invention effect: the development of holding biologics, its biological reagent, low temperature medicine, vaccine etc. are also more and more, classification and temperature requirement be each difference and segmentation to some extent also, in order to use the product of-19 ℃ to-26 ℃ preservations and freight charges can have personalized quality guarantee, at-19 ℃ of this invention to-26 ℃ of low temperature ice bags, for its solution need to be at storage and the transportation cold chain of biological reagent, low temperature medicine, vaccine and the food of this temperature province cold insulation.
The specific embodiment
A kind of-19 ℃ are to-26 ℃ of low temperature ice bags, in described ice bag, composition is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, ethylene glycol 40 weight portions, pure water 55 weight portions, triethanolamine 0.25-0.5 weight portion, and ethylene glycol is the main component of anti-icing fluid, a kind of colourless, transparent, sweet taste and there is hygroscopic thick liquid slightly, it can be with any ratio and water when molten, when the concentration of its ethylene glycol is different, freezing point is also different, when ethylene glycol 40 weight portion, its freezing point is-22.5 ℃, when this ice bag is placed on to cryogenic freezing accumulation of energy, it just starts to freeze at-22.5 ℃, can be very stable by ice source perseverance degree between-19 ℃ to-26 ℃, vaccine to temperature requirement at-19 ℃ to-26 ℃, food has played insulation effect.
Claims (2)
1. one kind-19 ℃ to-26 ℃ of low temperature ice bags, it is characterized in that the interior composition of described ice bag is comprised of the component of following weight portion: polyvinyl alcohol 2-3 weight portion, CMC cellulose or sustained release agent 1-2 weight portion, ethylene glycol 40 weight portions, pure water 55 weight portions, triethanolamine 0.25-0.5 weight portion.
2.-19 ℃ of preparation methods to-26 ℃ of low temperature ice bags described in claim 1, it is characterized in that: first by polyvinyl alcohol and pure water Hybrid Heating, after making it cooling, again with CMC cellulose, triethanolamine mix and blend, until product, become after paste, finally add ethylene glycol, stir and prepare composition in ice bag, then adopt conventional method to prepare ice bag.
