Problems solved by technology

The coolant in the disposable ice pack is divided into two parts, one part is ammonium nitrate and the other is crystalline sodium carbonate. When using, the central seal is pulled off, and the two chemicals are mixed together, and the temperature of the ice pack drops to 0°C The following; the main defect of this kind of ice pack is that the packaging cost is high, and it has a cooling effect when used. If the inner packaging bag is damaged, the function of the ice pack will be lost.
Also, it is only available for one-time use, so usage is low

Embodiment 1

[0024] A kind of manufacturing steps of the ice bag that can be repeatedly applied to the preservation of biological products is as follows:

[0025] (1) Put water and superabsorbent resin into a sealed plastic bag at the same time, for example: add 200ml of water to 2g of superabsorbent resin; the superabsorbent resin used in this example is polyacrylic acid resin;

[0026] (2) Soak the polyacrylic acid resin in water for 15 minutes to form a hydrogel;

[0027] (3) Place water and polyacrylic resin plastic bags flatly or determine the shape as required before freezing;

[0028] (4) Put the plastic bag in a cold storage, freezer or refrigerator at minus 10-20°C, and freeze for more than 12 hours; the temperature suitable for the storage and distribution of biological products is 2-8°C.

[0029] In this embodiment, the superabsorbent resin has adopted polyacrylic resin; polyacrylates, polyvinyl alcohols, vinyl acetate copolymers, polyurethanes, polyethylene oxides, starch-link...

Embodiment 2

[0031] The production steps of the biological ice pack are as follows:

[0032] (1) Put water and polyacrylic resin into a sealed plastic bag at the same time, for example: add 10g of superabsorbent resin to 500ml of water;

[0033] (2) Soak the polyacrylic acid resin in water for 25 minutes to form a hydrogel;

[0034] (3) Place water and polyacrylic resin plastic bags flatly or determine the shape as required before freezing;

[0035] (4) Put the plastic bag in a cold storage, freezer or refrigerator at minus 10-20°C, and freeze for more than 12 hours; the temperature suitable for the storage and distribution of biological products is 2-8°C.

[0036] Others are with embodiment 1.

Embodiment 3

[0038] A kind of manufacturing steps of the ice bag that can be repeatedly applied to the preservation of biological products is as follows:

[0039] (1) Put water and polyacrylic resin into a sealed plastic bag at the same time, for example: add 300ml of water to 8g of superabsorbent resin;

[0040] (2) Soak the polyacrylic acid resin in water for 20 minutes to form a hydrogel;

[0041] (3) Place water and polyacrylic resin plastic bags flatly or determine the shape as required before freezing;

[0042] (4) Put the plastic bag in a cold storage, freezer or refrigerator at minus 10-20°C, and freeze for more than 12 hours; the temperature suitable for the storage and distribution of biological products is 2-8°C.

[0043] Others are with embodiment 1.

Abstract

The invention relates to an ice bag capable of applying in preserving biological product repeatedly and a method for preparing the ice bag. The ice bag adopts a sealed plastic bag, mixed solution proportioned by super absorbent resin 1 to 6g per 100ml water is sealed in the bag, and the bag is frozen with the temperature of 10 to 20DEG C below zero for more than 12h. The super absorbent resin comprises one of polyacrylic ester type, polyvinyl alcohol, ethylene-vinlacetate copolymer, polyurethanes, polyethylene oxide, starch grafting copolymer, and composite water absorbing materials mixed with rubber, or combination of any two above materials. The preparation comprises the following steps: firstly, placing water and super absorbent resin into a sealed plastic bag simultaneously, adding super absorbent resin 1 to 6g into each 100ml water, secondly, dipping the super absorbent resin into water for 10 to 30min to form aquagel, thirdly, placing the plastic bag flatly or confirming the shape according to demands before freezing, fourthly, placing the plastic bag into a refrigerating room, an ice chest or an ice box with the temperature of 10 to 20DEG C below zero, and freezing for more than 12h. The ice bag has simple manufacture and prominent effect.

Description

technical field [0001] The invention relates to a physical cooling agent and a production method thereof, in particular to an ice bag which can be repeatedly applied to biological product preservation and a production method thereof. Background technique [0002] The refrigerated logistics industry is established with the advancement of science and technology and the development of refrigeration technology. It is based on refrigeration technology and uses refrigeration technology as a means. The logistics phenomenon under low temperature conditions requires special equipment and attention to the transportation process. , Time control and special logistics form of transportation type. With the high development of China's cold chain logistics, especially the specialized cold chain logistics of medicine and vaccines, phase change energy storage technology has increasingly become a focus of attention in China's logistics industry. Phase change cold storage technology has been w...
