Problems solved by technology

[0003] At present, there is no cold storage ice box or ice bag with ultra-low temperature phase change material as the content. The contents of common ice boxes or ice bags are mainly superabsorbent resin or thickener, which cannot achieve the real cold storage effect. After cold storage, the low temperature is maintained. The time is short. Generally, after 48 hours of cold storage in a refrigerator at minus 14 degrees to minus 18 degrees, the initial temperature can only reach about minus 13 degrees. In an environment of 28 degrees, the time it takes for the release temperature to reach 0 degrees is 30 minutes to 90 minutes, the cold storage effect is poor

Embodiment Construction

[0025] The substantive content of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments:

[0026] like figure 1 Shown: A production process of low-temperature phase-change cold storage ice boxes or ice packs. The process is implemented in six steps: box or bag making, trimming or trimming, internal material stirring, filling, sealing and boxing:

[0027] The first step is to make bags. Install the pre-designed mold in the shape of an ice bag on a high-frequency machine or a heat-sealing machine, and weld the upper and lower layers of plastic cloth or plastic composite cloth together to form a surrounding bag, and reserve a filling port; The mold in the shape of an ice box is installed on a blow molding machine or a plastic machine for blow molding or injection molding, and an enclosed ice box is made, and a filling port is reserved;

[0028] The second step is to cut the edges. For ice packs...

Abstract

The invention discloses a production process of a low temperature phase change cold accumulation ice box or ice bag in the field of phase change material cold accumulation containers. The production process is implemented according to six steps including box or bag manufacturing, edge cutting or trimming, internal material stirring, filling, sealing and encasement. Purified water, ammonium chloride, sodium chloride, sodium carboxymethyl cellulose and antibacterial agents are slowly added into a reaction kettle in sequence; then, internal materials are stirred sufficiently, wherein the accurate ratio of the internal materials is 78.9 to 15.5 to 2.5 to 3 to 0.1; the stirred internal materials are poured in the ice box or ice bag, sealed and encased. The production process has the advantages of being good in cold accumulation effect, wide in usage, good in shaping performance (smoothness), suitable for low temperature refrigeration and freshness preservation, environmentally friendly and safe, lowering use cost, saving energy and power, shortening cold accumulation time, reducing cold accumulation space and the like.

Description

technical field [0001] The invention relates to a production process of a cold storage container containing a high-efficiency polymerized ultra-low temperature phase change material, more specifically, the invention relates to a low temperature phase change cold storage ice box or ice box [0002] Bag production process. Background technique [0003] At present, there is no cold storage ice box or ice bag with ultra-low temperature phase change material as the content. The contents of common ice boxes or ice bags are mainly superabsorbent resin or thickener, which cannot achieve the real cold storage effect. After cold storage, the low temperature is maintained. The time is short. Generally, after 48 hours of cold storage in a refrigerator at minus 14 degrees to minus 18 degrees, the initial temperature can only reach about minus 13 degrees. In an environment of 28 degrees, the time it takes for the release temperature to reach 0 degrees is 30 minutes to 90 Minutes or so, ...
