摘要
为了掌握烟用爆珠制备核心技术,得到压破强度和形变量可控的乳化法爆珠制备方法,通过调节乳化液和二次强化溶液中氯化钙质量分数,研究爆珠压破强度和形变量的变化规律,并利用热重方法分析了爆珠胶皮的热稳定性。结果表明:①通过爆珠生长动力学研究,发现爆珠滴制过程中胶皮质量差异小于10%。②乳化液中氯化钙质量分数与爆珠的压破强度呈正相关,与形变量呈弱负相关。③二次强化溶液中氯化钙质量分数小于等于0.5%时,爆珠压破强度和形变量无显著变化;二次强化溶液中氯化钙质量分数大于0.5%时,氯化钙质量分数和爆珠压破强度及形变量均呈正相关。④钙离子提高了海藻酸中羟基的稳定性,增强了爆珠的韧性。
In order to master the core technology of preparing breakable capsules for cigarettes and obtain the method for preparing breakable capsules with controllable crushing strength and deformation variables,by adjusting the concentration of calcium chloride(CaCl_(2))in the emulsion and the secondary strengthening solution,the changing law of the bursting strength and deformation variables of the breakable capsules was studied.The thermogravimetric method was used to analyze the thermal stability of the breakable capsule shells.The results showed that:(1)according to the research on the growth kinetics of breakable capsules,the difference in shell weight was less than 10%(by mass)during the dropping process of breakable capsules.(2)The mass concentration of CaCl_(2)in the emulsion was positively correlated with the crushing strength of the breakable capsules,and it was weakly negatively correlated with the deformation variables of the breakable capsules.(3)When the mass concentration of CaCl_(2)in the secondary strengthening solution was less than or equal to 0.5%,the crushing strength and deformation variables of the breakable capsules had no significant changes.When the mass concentration of CaCl_(2)in the secondary strengthening solution was greater than 0.5%,the mass concentration of CaCl_(2)was positively correlated with the crushing strength and deformation variables of the breakable capsules.(4)Calcium ions improved the stability of the hydroxyl group in alginic acid and enhanced the tenacity of the breakable capsules.
