封瓶口胶帽套在制药、食品工业、医院药房沿用已久。但5～10毫升管状瓶封口的胶帽套缺货(因小而难制),所以在生产上用蜡封口。蜡封瓶口,不美观、不坚固。封瓶口时蜡温高塑料塞易松动,运输、搬动易脆裂脱落,因而失去封口作用,瓶内药液易变质。若改用火棉胶封瓶口,火棉胶成膜也易破裂。笔者经试用涂膜剂代替火棉胶封瓶口,成膜性能较火棉胶好,且美观。现将封瓶口胶液配方和使用方法简介如下。
Sealing caps have been used for a long time in the pharmacy, food industry and hospital pharmacy. However, 5 to 10 milliliters of plastic bottle caps sealed by a tubular bottle are out of stock (due to their small size), so they are sealed with wax in production. Wax sealed bottle mouth, not beautiful, not strong. When the bottle sealing mouth is high, the wax temperature is high and the plastic plug is easy to loosen. The transportation and handling of the plastic plug are easy to crack and fall off, so that the sealing effect is lost and the liquid in the bottle is easily degenerated. If you change the bottle mouth with fire rubber, fire cotton glue film is also easy to break. The author tried the coating agent instead of the fireproof rubber to seal the bottle mouth, the film forming performance is better than the fire cotton glue, and beautiful. The following is a summary of the formulation and usage of the sealer glue solution.
