關於火棉膠的製造,藥典上並無記載,因藥典只要求用现存的火棉溶解在醚醇混合液内製成火棉膠。市面上買不到現成的火棉,因此必須從原料脫脂棉做起;但由於各藥劑書上所載的製造方法,說得不够詳細,且不一致,而工业書上的方法雖然具體,而所用的混酸量又和各藥劑書上所叙述的有很大區别,一般限於设备,自然不能依樣搬到實驗室來製造。為此,我們在研究配合教學的原則下,根据下列的處方作了一系列的實驗。
Regarding the manufacture of collodion glue, there is no record in the pharmacopoeia because the pharmacopoeia only requires the use of existing cotton wool dissolved in ether alcohol mixture to make collodion. There is no ready-made fireproof cotton on the market. Therefore, it is necessary to start from the raw material absorbent cotton. However, due to the manufacturing methods contained in each Pharmacy Book, it is not very detailed and inconsistent, and the method in the industrial book is specific and used. The amount of mixed acid is again very different from that described in each Pharmacy Book and is generally limited to equipment. Naturally, it cannot be manufactured in the laboratory. To this end, we have conducted a series of experiments based on the following prescriptions under the principle of research and cooperation.
