Problems solved by technology

[0003] Cold storage technology is currently widely used, and the types of cold storage agents are constantly being updated. Some of them add polyN-vinylacetamide and sodium borate to sodium chloride aqueous solution to make cold storage agents; there is also a cold storage agent, which is Polyvinyl alcohol and borax, which are fully swollen in water, cross-link to form a body structure, and then absorb a large amount of water to swell into a translucent and easy-flowing gel. In the existing cold storage technology, a large amount of ammonium nitrate, ammonium chloride, and chlorine are used. Sodium chloride, potassium chloride, calcium chloride,

Abstract

A cold accumulating agent in the form of gel is prepared from attapulgite clay, urea, high-hydroscopicity resin and water through proportional mixing and stirring. Its advantages are high effect and no environmental pollution.

Description

Technical field: [0001] The invention relates to a cold storage agent, in particular to an attapulgite gel cold storage agent. Background technique: [0002] At present, energy resources are relatively tight, so it is necessary to vigorously promote cold storage technology. Using the low power at night, the cold storage agent is used for cold storage, and the cold storage agent is used for cooling during peak power consumption, which can be widely used in refrigerators, freezers, freezers, air conditioners and low temperature. In transportation and other occasions that require cooling, it has the function of shifting peaks and filling valleys for the power grid, and can reduce or postpone the construction of power plants and other power facilities, so it has good social benefits; at the same time, because the difference in peak and valley electricity prices is used, users can Save money on electricity bills. [0003] Cold storage technology is currently widely used, and the...
