摘要
以乙烯-醋酸乙烯酯共聚物为壁材,水为芯材,采用滴丸机制备了卷烟用水溶性芯材爆珠。探究了冷却液组成和温度、爆珠滴落高度、壁材粘度、以及芯材温度等工艺条件对爆珠形状、壁厚以及包水率的影响。结果表明,冷却液中乙醇与水体积比为100∶6,温度为25℃,爆珠滴落高度为1 cm,壁材熔融粘度为200~269 MPa·s,芯材温度为65℃时,可制得圆度好,壁厚较为均匀的爆珠。所制得的爆珠包水率可达80%,且保水性能优异,保存180 d后,水分流失率在2%左右。
Using ethylene-vinyl acetate copolymer as wall material and water as core material,the water-encapsulated cigarette capsule was prepared by pill dropping machine.The influences of coolant composition and temperature,drop height of the capsule,melt viscosity of wall material and core material temperature on the capsule shape,wall thickness and water content were investigated.The results showed that the cigarette capsules with good roundness and uniform wall thickness could be obtained under optimized following conditions:the volume ratio of ethanol to water in coolant was 100∶6;the coolant temperature was of 25℃;the drop height of the capsule was 1 cm;the melt viscosity of wall material was 200~269 MPa·s,and the temperature of core material was 65℃.The water content of the as prepared capsules reached 80%,and the water loss rate was less than 2%after a storage time of180 days indicating an excellent water retention performance.
