【摘要】：由高吸水性樹脂和無(wú)機(jī)鹽組成的蓄冷材料具有良好的實(shí)用性，適用于物理降溫、冷敷理療，現(xiàn)在已成為醫(yī)療衛(wèi)生機(jī)構(gòu)降溫冷敷的首選產(chǎn)品。但目前市面上的這種蓄冷材料冷敷袋存在反應(yīng)后是液體狀態(tài)，易于流動(dòng)，且制冷時(shí)間也相對(duì)較短，不能重復(fù)使用，消耗量大等問(wèn)題，為醫(yī)護(hù)人員提供的便利有限。本研究以高吸水性樹脂為主要原料，優(yōu)化出一種冷量釋放均勻且緩慢，保冷時(shí)效佳等特點(diǎn)的蓄冷材料。 本研究通過(guò)測(cè)量經(jīng)過(guò)冷凍的樹脂在同一室溫下溫度隨時(shí)間的變化關(guān)系來(lái)測(cè)量四種高吸水性樹脂材料的蓄冷效果，對(duì)四種不同生產(chǎn)廠家的高吸水性樹脂A、B、C和D的水溶液進(jìn)行濃度優(yōu)化研究。結(jié)果表明，在0.2%——1.0%濃度范圍內(nèi)，優(yōu)化濃度分別為：樹脂A為0.8%、樹脂B為0.4%、樹脂C為0.6%、樹脂D為0.8%；在0.8%——4.5%濃度范圍內(nèi)，優(yōu)化濃度分別為：樹脂A為2.5%、樹脂B為0.8%、樹脂C為1.5%、樹脂D為1.5%。綜合比較四種樹脂的蓄冷效果發(fā)現(xiàn)1.5%的樹脂C溶液的蓄冷效果最佳。 在樹脂A水溶液中分別添加NaCl、Na2SO4和Na2CO3發(fā)現(xiàn)由于溶解平衡的影響，，反而使樹脂的蓄冷效果變差。此外，從樹脂本身的性質(zhì)分析，探究不同吸水倍率和粒徑大小對(duì)樹脂蓄冷效果的影響。研究結(jié)果表明吸水倍率對(duì)同種濃度下樹脂溶液的蓄冷效果影響規(guī)律不顯著；而樹脂粒徑小對(duì)樹脂蓄冷效果有利，但具體的規(guī)律還有待進(jìn)一步研究。
[Abstract]:The cold storage material composed of super absorbent resin and inorganic salt has good practicability and is suitable for physical cooling and cold compress physiotherapy. Now it has become the first choice of cooling cold compress in medical and health institutions. But at present, the cold dressing bag of this kind of cold storage material on the market has a liquid state after reaction, is easy to flow, and the refrigeration time is relatively short, can not be reused, and the consumption is large, so the convenience for medical and medical personnel is limited. In this paper, the superabsorbent resin was used as the main raw material to optimize a cold storage material with the characteristics of uniform and slow cold release, good cold retention aging and so on. The cold storage effects of four kinds of super absorbent resin materials were measured by measuring the relationship between temperature and time of the frozen resin at the same room temperature, and the cold storage effects of four kinds of super absorbent resins A, B, B were measured by measuring the relationship between the temperature and the time of the frozen resin at the same room temperature. The concentration optimization of aqueous solution of C and D was carried out. The results showed that the optimum concentration was 0.8% for resin A, 0.4% for resin B, 0.6% for resin C and 0.8% for resin D in the concentration range of 0.2% / 1.0%. In the range of 0.8% / 4.5%, the optimum concentration was 2.5% for resin A, 0.8% for resin B, 1.5% for resin C and 1.5% for resin D, respectively. A comprehensive comparison of the cold storage effects of four resins shows that 1.5% resin C solution has the best cold storage effect. The addition of NaCl,Na2SO4 and Na2CO3 to the aqueous solution of resin A showed that the cold storage effect of the resin became worse due to the influence of dissolution equilibrium. In addition, from the analysis of the properties of the resin itself, the effects of different water absorption rates and particle sizes on the cold storage efficiency of the resin were investigated. The results show that the water absorption ratio has no significant effect on the cold storage effect of the resin solution at the same concentration, but the small particle size of the resin is beneficial to the cold storage effect of the resin, but the specific law needs to be further studied.
