preparation example Construction

[0030] Two, the preparation method of long-term refrigeration ice pack

[0031] A preparation method for preparing a long-acting refrigerated ice pack, comprising the steps of:

[0032] Step 1, first mix CMC and guar gum in a stirred tank in proportion and fully mix them for later use; among them, 1-2 parts of CMC, 0.5-1 part of guar gum and 95-98 parts of deionized purified water; preferably , 2 parts of CMC, 0.8 parts of guar gum and 97.7 parts of deionized purified water.

[0033] Step 2, after injecting deionized pure water into the reaction kettle in proportion, adding the CMC and guar gum fully mixed in the step 1, the stirring time is 30 minutes;

[0034] Step 3, after the step 2 is stirred evenly, the closed-loop pipeline is filled in the outer bag, and the long-acting refrigeration ice bag can be obtained.

[0035] The outer bag is a soft storage bag; the soft storage bag is a medical non-toxic plastic bag.

[0036] 3. Refrigeration experiment

[0037] 1. The infl...

Embodiment 1

[0039] A kind of long-term refrigerated ice bag, comprises outer bag and the mixture sealed in the outer bag, the weight percent of each component of the mixture is: 1 part of CMC, 0.5 part of guar gum and 95 parts of deionized purified water, The outer bag is 500 milliliters, and 250 milliliters of the mixture is injected into the outer bag.

Embodiment 2

[0041] A kind of long-acting refrigerated ice bag, comprises outer bag and the mixture sealed in the outer bag, the weight percent of each component of the mixture is: 1.5 parts of CMC, 0.7 parts of guar gum and 96 parts of deionized purified water, The outer bag is 500 milliliters, and 250 milliliters of the mixture is injected into the outer bag

Abstract

The invention provides a long-acting refrigeration ice bag which comprises an outer bag and a mixture sealed in the outer bag, and the mixture comprises the following components in parts by weight: 1-2 parts of CMC, 0.5-1 part of guar gum and 95-98 parts of deionized purified water. The preparation method has the beneficial effects that the production efficiency is improved, the reaction time is shortened to 20-30 minutes from the original 50-80 minutes, and the efficiency is improved by 61 percent; the loss of a manual operation link is reduced, the production rate is increased to 36-45 bagsper minute from 25-30 bags per minute, and the rate is increased by 50%.

Description

technical field [0001] The invention relates to the field of ice packs, in particular to a long-acting refrigeration ice pack and a preparation method thereof. Background technique [0002] Chemical ice packs are made by using the principle that certain chemical substances (such as ammonium salts) absorb heat during the dissolution process, and the temperature in the bag drops rapidly. It is mainly used in medical care (such as cold compress to reduce swelling), or food preservation, or medicine (such as vaccine) cold storage, etc., and has good results. In short, chemical ice packs play a relatively important role in daily life. [0003] The traditional cold storage agent is made of resin mixed with water. The existing patent CN101694338A discloses a cold storage agent made of polymer water-absorbing resin and water. The ice pack cold storage agent prepared by the above technical scheme has defects such as short cold storage time, high cost, and narrow phase transition te...
