摘要：以羧甲基壳聚糖为原料添加无机盐,制得调湿材料。研究了实验因素,如无机盐的种类,无机盐的用量对调湿材料的调湿性能的影响。结果表明:无机盐选用KAc,用量占总量的50%时,调湿材料在相对湿度为30%、50%、70%下吸湿量分别可达26.2%、45.5%和86.0%,同时具有较好的放湿能力。
A humidity controlling material was obtained by adding inorganic salt to carboxymethyl chitosan, We studied me faets which effect the property, such as the kind and amount of the salts. Experimental results showed that the best selection of salt is KAe. The humidity controlling material has the good capability of both adsorption and desorption. When the KAe, 50% of the total weight was added into carboxymethyl ehitosan,its water adsorption pereent is 26. 2%;15. 5% and 86%, in RH30% ;RH50% and RH70% respectively.
