Abstract
The invention relates to a phase-change constant-temperature material and a manufacture process thereof. The phase-change constant-temperature material comprises the following components in mass percent: 62% of sodium sulfafe decahydrate, 5% of borax, 3% of water, 20% of glycerol, 5% of calcium chloride and 5% of sodium carboxymethylcellulose. By adopting the phase-change constant-temperature material and the manufacture process thereof, the technical problem that an existing cold-accumulation phase-change memory material is always blocked after being molten and congealed is mainly solved; iced blend particles of sodium sulfafe decahydrate that is the phase-change material are finer, and thus the problem which plagues the ice mat industry for a long term is solved, and the best experience is provided for customers.
Description
Technical field
The present invention relates to cold-storage constant temperature phase change material memory-phase change material sal glauberi (sorbet), particularly a kind of phase-change constant-temperature material and manufacture craft thereof.
Background technology
Cold-storage constant temperature phase change material memory-phase change material sal glauberi (sorbet) is packed into as weighting material and is made the sorbet pad in the matrix material.The heat that absorbs human body when sorbet pad contact human body slowly melts, the temperature difference with human normal body temperature maintenance 6-7 degree, make body temperature on the basis, reduce the 3-5 degree, make us body and remain on comfortable, a nice and cool state, and when room temperature drop to 27 degree when following sorbet can automatically solidify, so recycle.Making you spend a salubrious pleasant summer, and reduce the use of air-conditioning, is the household supplies of real environmental protection.
But above-mentioned existing product in use can often have caking phenomenon after the thawing of cold-storage constant temperature phase change material memory is condensed again.
Summary of the invention
The object of the present invention is to provide a kind of phase-change constant-temperature material and manufacture craft thereof, mainly solve the technical problem that can often have caking phenomenon after existing cold-storage constant temperature phase change material memory thawing is condensed again, it makes the Sorbet particle of phase change material sal glauberi trickleer, solved the difficult problem of long-term puzzlement ice pad industry, preferably experienced for the human consumer.
For achieving the above object, the present invention realizes like this.
A kind of phase-change constant-temperature material is characterized in that: the composition according to mass percent is sal glauberi 62%, borax 5%, water 3%, glycerol 20%, calcium chloride 5% and Xylo-Mucine 5%.
A kind of manufacture craft of aforesaid phase-change constant-temperature material, it is characterized in that: split two stainless steel vessels, the raw material of first container weighing ratio, in glycerol, add Xylo-Mucine, borax and calcium chloride, rapid stirring makes it abundant dissolving, the sal glauberi of the mass ratio that second container weighing is suitable adds an amount of pure water, makes it abundant mixing; The raw material of the first container is added second container fully to be stirred and got final product in 50 minutes.
Phase change material transformation temperature of the present invention is at the 26-29 degree, and latent heat of phase change is at 198-257KJ/KG, and phase transition process is reversible, and the number of times that can be recycled is more than 5000 times, and raw material is scale production, and is cheap, and is nontoxic without corrosion, is easy to promote.This phase change material snow that is white in color when normal temperature is cotton-shaped, and certain elasticity is arranged, and plasticity very easily is convenient to each energy storage field development and use.
Innovative point in the materials and methods of the present invention is: add glycerol in the prescription of the present invention, because the transparent thick liquid of glycerol appearance colorless, odorless, tasteless, have water absorbability, humectation, a property of softening, moisture in the extremely aobvious absorbing air, it is neutral that the aqueous solution is, and can mix with water, ethanol, methyl alcohol arbitrary proportion.Density 〉=1.260, boiling point 〉=120 degree, freezing point has good freeze-proof below-26 degree.So in covert material, the speed of crystallization is slowed down, be that crystal caking phenomenon after this condenses after melting disappears and keeps the flexibility of the particle after the crystallization.
Sal glauberi loses crystal water and is thenardite, claims again Sodium sulfate anhydrous.min(99), is the matrix components of heat-storage agent.Borax formal name used at school sodium tetraborate is done the karyogenesis agent in covert material, play to promote sal glauberi crystallization and the effect that crystallization is evenly generated.Glycerol is the essential composition of covert material, can impel the sal glauberi crystallization except cooperating with borax, also make the crystallization of sal glauberi loose, soft, contact with human body comfortable.Pure water is as heat-transfer medium, and it is indispensable.Calcium chloride can make the refrigerant sense that increases Sorbet.
The advantage that the ice spacer that uses material of the present invention to make has is:
The ice pad outside temperature of 1, making can directly be used more than 27 degree, need not electricity consumption, the source of not consuming energy, and cooling-down effect is obvious, and the contact human body several seconds just can feel refrigerant comfortable.But can not allow the people catch a cold because of long-time the use.
2, the caloric receptivity of Sorbet pad is more than 35 times of identical weight water cushion or gel mat.Under the 27 degree environment, can automatically solidify, return to the Sorbet solid state.Temperature is lower, and setting time is short.
3, Humanity Design, fabric texture is soft and smooth, need not to worry to scratch notebook computer and people's health.Radiationless, the toxicological harmless goods and materials, environmental-protecting material, to human body without any injury.And but Reusability is more than 3 years.
4,0.8Kg weight is collapsible, and is portable superpower.Overcoat adopts high-quality antibacterial surface mildew-resistant terylene matrix material to form through the high frequency heat seal, can withstand voltage 200 kilograms break.
5, energy-conserving and environment-protective need not power supply, effectively prolong the work-ing life of cells in notebook computer and major parts.
6, novelty, fashion, be applicable to office, SOHO, outdoor leisure, all can use on desktop, knee, the bed
7, this product is attractive and durable, can not only play nice and cool effect, and can relieve summer heat analgesic except miliaria, cooling, to hemorrhoid, hypertension, hot summer weather insomnia, long-term bed, the auxiliary effect for the treatment of is arranged.
