Abstract
The invention discloses a cryogenic cold storage material composition which is formed by inorganic salts and mainly comprises water, calcium chloride, potassium chloride, calcium hypochlorite, aerosol and polyacrylamide. The cold-storage temperature of the cryogenic cold storage material composition is (-19)-(-21) DEG C, and the cold storage amount is more than 290kJ/kg.
Description
Technical field
The present invention relates to a kind of low temperature storage cold material compsn, it stores up cold temperature be-21～-19 ℃, add a certain proportion of thickening material after, effectively overcome the problem of saltouing under the low temperature, make and store up cold material and have splendid stability.According to the resulting low temperature of the present invention storage cold material compsn, can be used for the deepfreeze, accumulating of perishable prod etc.
Background technology
Refrigerated shipment receives the influence of outside atmosphere bigger, and Refrigeration Technique is had higher requirements, and is link the weakest in each link of Cold Chain Logistics.China is annual because the perishable prod waste that refrigerated shipment causes accounts for 25%～30% of whole cold chain perishable prod waste.In the refrigerated shipment process; The product that refrigerator carriage generally adopts the onboard fuel compressor to carry out in transit is fresh-keeping or freezing, though can be according to the storage request control vehicle interior temperature of shipping products, transportation cost is higher; According to statistics; China's refrigerated shipment cost accounts for 70% of product total cost, must not be far above the refrigerated shipment cost above the international standard of product total cost 50%, and wherein energy consumption for cooling accounts for quite great proportion in the transportation cost; And fuel compressor on average per hour is used for refrigerating consumption oil about about 3L, and this has constituted sizable cost pressure.In addition, the consumption environmental pollution of fuel, carbon emission etc. all produce negative influence.
In addition, in the short distances transportation process, also solve of short duration deepfreeze problem with ice cube usually, but, only can make temperature maintenance in the compartment in 0～10 ℃ of scope, can not satisfy the storage requirement of frozen prods because the melting point of ice is 0 ℃.
The present invention has announced a kind of low temperature storage cold material compsn; It stores up cold temperature can remain on-21～-19 ℃; The storage cold can be kept enclosed environment temperature-18 ℃ with this material as cold storage material up to 290kJ/kg, can satisfy the preservation demand of most of frozen prodss.Adopt the organic and composite thickener system of mineral compound in the invention prescription simultaneously, solved inorganic salt at low temperatures owing to solubleness reduces layer sedimentation problem of analysing that causes.
Summary of the invention
The object of the present invention is to provide a kind of low temperature storage cold material compsn; Storing up cold temperature is-21～-19 ℃; The storage cold can be used for the refrigeration (like refrigerator carriage, freezer, small-sized vehicle-mounted insulation can etc.) of the good enclosed space of insulation up to 290kJ/kg, does not use fuel compressor; Improve the comprehensive utilization ratio of the energy, reduced pollutant emission.
