Embodiment 1

[0024] Embodiment 1: The making and use of ultra-low temperature instant cooling ice pack

[0025] (1) Make 100g ice packs

[0026] A. Use OPP+PE composite film to make the inner water bag, fill it with 40ml of water, heat seal it to make the inner water bag;

[0027] B. 45g of urea and 15g of ammonium chloride are packed in the nylon composite outer bag;

[0028] C. Put the inner water bag into the nylon composite outer bag, heat seal the outer bag, and get 100g of ice bag finished product.

[0029] (2) Make 120g ice packs:

[0030] A. Use PET+PE composite film to make the inner water bag, fill it with 50ml of water, heat seal it to make the inner water bag.

[0031] B. Put 50g of urea and 20g of ammonium chloride into a nylon composite outer bag.

[0032] C. Put the inner water bag into the nylon-nylon composite outer bag, and seal it with heat to obtain a finished product of 120g ice bag.

[0033] When using the ice packs of the above specifications, pinch the inner wa...

Embodiment 2

[0034] Embodiment 2: Performance comparison of ultra-low temperature instant cooling ice packs

[0035] The inventor compares the product of the present invention with a plurality of products currently on the market. Samples from two different manufacturers were taken from Shenzhen, Guangzhou, and Shanghai for comparison. The samples were left at room temperature for 2 hours to bring the sample mass to the same temperature as room temperature. In order to make the products comparable, the inventor took a beaker of the same size, poured the material into the beaker first, then cut the corresponding water bag, poured it into the beaker, started timing, stirred at an even speed to the lowest temperature, and stopped stirring. , to record the time. And observe the temperature situation, record the time required for the product to rise from the lowest temperature to 15 degrees. The comparison results are as follows:

[0036]

[0037] Through the comparison of experimental re...

Abstract

The invention discloses a manufacturing method of an ultralow-temperature instantaneous cooling ice bag. The ice bag is composed of a refrigerant, water, an inner water bag body and an outer packaging bag body, wherein the refrigerant and the inner water bag body are contained in the outer packaging bag body, the refrigerant is wrapped between the outer packaging bag body and the inner water bag body, and the water is contained in the inner water bag body. The refrigerant is prepared by mixing urea and ammonium chloride at the ratio of 3:1. When the ice bag is used, the inner water bag body in the outer packaging bag body is broken in a pinching mode, the refrigerant makes contact with the water to fast react so that heat can be absorbed and refrigeration can be performed, the refrigerating temperature can be -4 DEG C or below, and the refrigerating time lasts for 40 min or more at room temperature. The ice bag can be used for performing medical hypothermia and fever abatement for high fever, diminishing inflammation to stop pain, performing cold compress to beautify faces, treating sprain, stopping bleeding, preventing festering, caring skin and performing other auxiliary physical therapy of cold and hot compress physical therapy bags.

Description

technical field [0001] The invention relates to a method for making an ultra-low temperature instantaneous cooling ice bag, which uses the principle of physical and chemical technology to use a mixture of urea and ammonium chloride as a refrigerant, and belongs to the fields of medical cosmetology, medicine, cosmetics and other industries. Background technique [0002] At present, there are many kinds of instant cooling ice packs on the domestic market, and they are uneven. The most common ice pack refrigerants are urea, ammonium nitrate, or a mixture of both. Although ammonium nitrate has a strong cooling effect and can reduce the temperature from room temperature to a few degrees below zero, it is an explosive product. With the stricter production safety control in the country, it is used as the source of ammonium nitrate for explosive products. are strictly controlled. Raw materials are not easy to purchase, and the purchase record and production management are extremel...
