LS-I沥青脆点仪工作原理 1、将仪器擦净,使之透明无暇,以便观察试验中的试样变化。 2、将沥青试样加热熔化,脱水,待冷却后称取重量相当于0.4Cm3沥青试样,将其置于烘箱内加热,使沥青熔融涂裹于干金属片上(注意要均匀),其厚度为0.5毫米。之后让涂有沥青的钢片在室温下冷却1小时。 3、取下大橡皮塞,在保温筒内放入适量固态二氧化碳和乙醇混合物(或丙酮),按原样安装好。 4、取下小橡皮塞(固定在塞的整体装置)将涂有沥青的钢片小心的夹在仪器的上、下夹头之间。 5、装上小橡皮塞及其它附件,按原样装配好,小心放入制冷槽内,然后慢慢注入干冰,使仪器冷却速度为每分钟降低1℃±0.5℃。 6、当温度降到预计的脆点温度10℃左右时,即按下弯曲,使仪器开始摆动。试验完后。如需升温则设定温度表所需温度,待升至设定温度即开始第二组试验。 7、当试件出现裂纹时的温度即为该沥青试样的脆点。同时按脆点锁存开关锁定。
