preparation example Construction

[0021] The technical solution adopted by the present invention to solve the technical problem is a preparation method of a phase-change cold storage material for the ecological ice-temperature preservation transportation of Penaeus vannamei, comprising the following steps:

[0022] a. Mix distilled water and anhydrous sodium sulfate at a mass ratio of 1.53:1, place in a constant temperature water bath at 40°C, stir and dissolve for 30 minutes, until there is no obvious precipitation in the lower part, and a mixed solution is formed.

[0023] b. Add sodium chloride, and the mass ratio of sodium chloride to anhydrous sodium sulfate is 0.45:1. Then add silicon dioxide and sodium tetraborate, the mass ratio of which is 0.18:1 to anhydrous sodium sulfate, and stir evenly; sodium chloride should be added slowly along the edge of the vortex stirred by the stirrer.

[0024] c. Add CMC to the sol obtained in step b, the mass ratio to anhydrous sodium sulfate is 0.04:1, adjust the stirr...

[0029] Fabrication of phase change cold storage materials.

[0030] Take 58mL of distilled water, heat it in a water bath to 40°C and place it at a constant temperature, accurately weigh 38g of anhydrous sodium sulfate, slowly add it to the constant temperature water, stir and dissolve for 30 minutes, until there is no obvious precipitation in the lower part. Weigh 17g of sodium chloride and slowly add it along the edge of the vortex stirred by the stirrer. Then accurately weigh 3 g each of silicon dioxide and sodium tetraborate, add to the solution, and stir. Finally, weigh 1.5g of CMC, slowly add it into the solution, adjust the stirrer to a higher speed, and stir at a constant temperature of 40°C for 3 to 4 hours, until the mixed solution system is stable and milky white gel-like, and no obvious salt particles exist. Put the mixed solution into an ultrasonic oscillator and sonicate for 2 hours until there are no crystals and particle precipitates (at this time, there is no...

[0033] Material insulation experiment.

[0034] according to figure 2 In the phase change material heat preservation experiment, the design method of placing the heat preservation bag according to the diagram is used for the test. The size of the heat preservation box is 400mm×220mm×275mm. Only 3 parts of phase change materials are placed in picture A, and 6 parts of materials are placed in picture B. After putting the phase change cold storage material into the incubator, seal it with adhesive tape. The incubator is placed in a room with a constant temperature of 25°C. The automatic temperature recorder record is set to 2min / time, and the temperature is recorded, and then the probe is inserted into the incubator along the blue hole in the middle, placed in the air, and the temperature data is collected at any time, and placed for 3 Days later, it was taken out for data processing.

[0035] After the incubator was placed in a constant temperature room at 25°C for 2 days, it...

Description

Technical field: [0001] The invention belongs to material application technology, and in particular relates to a phase-change cold storage material, which is a preparation method of the phase-change cold storage material suitable for ecological ice-temperature preservation and transportation of Penaeus vannamei. Background technique: [0002] In comparison, the price of live aquatic products is several times higher than that of frozen products. Keeping alive transportation is the most effective way to maintain the best freshness of aquatic products to meet consumer demand, and it also improves the economic benefits of enterprises. Traditional transportation methods for aquatic products are generally divided into water transportation and non-water transportation. Compared with water transportation, non-water transportation has the advantages of increased transportation density, prolonged transportation time, no need for water quality management, and saving transportation. Low...
