| 目的 通过复合调湿凝胶P（NAC）调控微环境的湿度，使微环境湿度处于相对稳定的状态，减少环境湿度变化对烟丝含水率的影响。方法 以异丙基丙烯酰胺、丙烯酸、羧甲基纤维素和丙三醇等为原料，通过自由基聚合合成具有调湿功能的凝胶材料；在不同湿度条件下，研究调湿凝胶P（NAC）对烟丝含水率的影响。结果 在相对湿度为60%的条件下对P（NAC）进行预处理。当环境相对湿度为40%~70%时，含有P（NAC）的烟丝含水率维持在10.94%~12.95%范围内，烟丝含水率变化幅度较小；不含P（NAC）的烟丝含水率在8.43%~14.36%范围内，烟丝含水率变化明显。结论 复合调湿凝胶P（NAC）在调控微环境湿度，减少烟丝含水率的变化，保持烟丝的稳定性与质量等方面，具有一定的实际应用价值。 |
| 英文摘要: |
| The work aims to control the humidity of the microenvironment with compound humidity control gel P(NAC), so that the humidity of the microenvironment is relatively stable, and the effects of changed environmental humidity on the moisture content of cut tobacco are reduced. The gel materials with humidity control function were synthesized from N-isopropylacrylamide (NIPAM), acrylic acid, carboxymethyl cellulose and glycerol by means of free radical polymerization. The effects of humidity control gel P(NAC) on the moisture content of cut tobacco were studied under different humidity. Pretreatment of P(NAC) was conducted under relative humidity RH=60%. When the ambient relative humidity was 40%-70%, the moisture content of cut tobacco containing P(NAC) changed slightly, in the range of 10.94%-12.95%; while the moisture content of cut tobacco without P(NAC) changed significantly, which was 8.43%-14.36%. The compound humidity control gel P(NAC) has certain practical application value in controlling the micro-environment humidity, reducing the moisture content change of cut tobacco, and maintaining the stability and quality of cut tobacco. |
