电热蒸馏水器使用一段时间之后,便会结垢。有人采用绑纱布的方法,使垢吸附在纱布上,利于清洗。然而,在蒸馏器壁及其它纱布难于复盖的部位,其垢的清洗,免不了要加盐酸处理。一般的蒸馏器系用钢材或铝材制成,长期用盐酸清洗,势必造成蒸馏器的锈蚀,影响其使用寿命。为克服上述毛病,我们采用六次甲基四胺(2%)的盐酸溶液(1+1)作为清洗剂。其中,六次甲基四胺 Electrothermal distilled water used for some time, it will scale. Some people use the method of binding gauze, dirt scale adsorption on the gauze, which will help clean. However, in the retort wall and other gauze hard to cover the site, the scale cleaning, inevitably need to add hydrochloric acid. The general distillation system made of steel or aluminum, long-term cleaning with hydrochloric acid, is bound to cause distillation of the rust, affecting its service life. To overcome the above problems, we use hexamethylenetetramine (2%) hydrochloric acid solution (1 + 1) as a cleaning agent. Among them, hexamethylenetetramine
