滤棒物性参数之间的相关关系

Relationships among Physical Parameters of Filter Rod

为研究滤棒圆周、重量、硬度、吸阻4要素间的相互关系,选用2 7Y/30000、3 0Y/35000、3 3Y/370003种常用规格的醋酸纤维丝束,进行了不同圆周、不同重量的滤棒成形试验。在不添加增塑剂的情况下,试验结果表明:①对于2 7Y/30000的醋纤丝束,滤棒的圆周每产生0 1mm的变化,将导致吸阻产生83Pa的变化,硬度产生0 43%的变化;滤棒的重量每产生0 01g/支的变化,将导致吸阻产生116Pa的变化,硬度产生1 18%的变化。②对于3 0Y/35000的醋纤丝束,滤棒的圆周每产生0 1mm的变化,将导致吸阻产生74Pa的变化,硬度产生0 49%的变化;滤棒的重量每产生0 01g/支的变化,将导致吸阻产生114Pa的变化,硬度产生0 88%的变化。③对于3 3Y/37000的醋纤丝束,滤棒的圆周每产生0 1mm的变化,将导致吸阻产生77Pa的变化,硬度产生0 53%的变化;滤棒的重量每产生0 01g/支的变化,将导致吸阻产生109Pa的变化,硬度产生1 31%的变化。

In order to investigate the relationships among circumference, weight, hardness and draw resistance, the filter rods of different circumferences and weights made of 27Y/30000, 30Y/35000 and 33Y/37000 tows without plasticizer were tested The results showed that 1) for the filter rod made of 27Y/30000 acetate tow, the draw resistance and hardness changed by 83Pa, 043% and 116Pa, 118%, respectively; 2) for the filter rod made of 30 Y /35000 tow, the draw resistance and hardness of filter rod were varied by 74Pa and 049% and by 114pa and 088%, respectively; 3) for the filter rod made of 33Y/37000 tow, the changes of draw resistance and hardness were 77Pa, 053% and 109Pa, 131%, respectively; when the circumference and weight of filter rod varied 01mm and 001g, respectively
