制备溶液
试样干燥：
将装有样品的瓷盘置于烘箱内干燥一小时,（或在红外线烘箱内干燥半小时）取出,
放入干燥器中,冷却至保温.其中含醇nitrocellulose需先挥酒0.5H ．
后于100 一l05 ℃ 条件下,干燥含水nitrocellulose于110 ℃ 士2 ℃ 条件下干燥,
根据不同规格,干燥nitrocellulose按下表制备溶夜
先称取规定量干燥试样于具塞三角瓶中,加乙醇,摇晃之后再加甲苯,摇晃均匀使试样完全浸润三分钟,
最后加乙酸乙酯,间歇摇晃使之完全溶解成为均匀的胶体溶液,静止至无气泡.
3.2
将上述胶液注入一干燥洁净的粘度管内,溶液应超过上刻线30mm 粘度管应与台面垂直,
于玻璃保温筒内静止保温不少于30min （此时管口应塞一塞子,以防溶剂挥发）待气泡全部上升到刻线以上．
取洁净的钢球从粘度管顶部中央自由落下,钢球至上刻线时开动秒表,
降至下刻线时,停止秒表,记录落球时间（即钢球经过两刻线的时间）,精准至0.1s
同时测量保温筒水温,精准至0.5 ℃ ,同一粘度管落三个钢球,其相对误差应小于5 %
(即最大值减最小值除以三结果平均值）.

Preparation of the sample drying solution : porcelain plates with samples placed in a drying oven within hours. (or in infrared drying the half-hour) Retrieve, Add dryers, cooling and insulation. Nitrocellulose containing alcohol which should first command liquor H 0.5. After a l05 100 ℃, nitrocellulose drying at 110 ° C ± 2 ° C under dry conditions, according to different specifications, dry nitrocellulose dissolved the table below Preparation first night called for drying the sample volume requirements in China with Cypriot flask increase ethanol, after shaking with toluene, shaking uniform specimen completely infiltration 3 minutes, add ethyl acetate, Intermittent shaking so that they become completely dissolved homogeneous colloidal solution, a non-static bubble. 3.2 Side of the above steps will be liquefied into a dry cleaner viscosity control, Solution should be carved on line more than 30 mm of viscosity and the surface should be vertical, in the glass tube static thermal insulation of not less than 30 min (At this point I should Cypriot control a stopper. prevent solvent evaporation) until all air bubbles rise to the moment above. Take clean ball from the top of the central viscosity of free sets, and the ball at the last moment line running stopwatch, to the next groove, stop stopwatch and record-ball (ball after two engraved lines of time), accurate to 0.1's simultaneous measurements of water temperature insulation cones, accurate to 0.5 ° C, the viscosity of the same three-ball, The relative error of less than 5% (that is, reduce the maximum three results divided by the minimum average).
