一电解部分 1 仪器用具 (1) 电解槽:3000ml烧坏和不锈钢圆筒(作阴极用)。 (2) 整流器:0～50伏;0～15安。 (3) 可变电阻:2.5安:0～100欧. (4) 直流电表:0～5安。 (5) 胶袋:6g硝酸纤维加100ml醇醚(1:4)混合液配制成火棉胶液。将胶液均匀地倒在套以玻璃环的倒立试管(内径5厘米,长15厘米)外壁上,待溶剂挥发后,将试管置流水下冲数分钟,小心地移出玻璃环,即取出成试管形状的胶袋,不用时需将其浸泡在水中。
An electrolysis part 1 apparatus (1) electrolyzer: 3000ml burned and stainless steel cylinder (for cathode). (2) Rectifier: 0 ~ 50V; 0 ~ 15A. (3) Variable resistance: 2.5A: 0 ~ 100E. (4) DC meter: 0 ~ 5A. (5) plastic bags: 6g nitrocellulose plus 100ml alcohol ether (1: 4) mixture prepared into cotton collodion. The glue is poured evenly on the inverted glass tube ring (5 cm in inner diameter and 15 cm in length) on the outer wall. After the solvent is evaporated, the tube is allowed to drain for several minutes and carefully removed from the glass loop, Shape plastic bags, when not in need of it soaked in water.
