一、前言目前国内灭蚊喷射剂绝大部分采用酒精作溶剂,由于酒精来源紧张,价格日趋上升,导致灭蚊喷射剂溶剂的成本超过原药成本,同时室内喷洒酒精会破坏地面、墙壁及家俱饰面。因此,近年来许多单位开始以水代酒精作溶剂的研究,并也有产品问世,但是,除虫菊酯类产品在水中不能长期稳定存在,以水作溶剂不能长期贮存,而且水剂产品包装大,运输极不方便。如果采用浓缩剂剂型,则可大量节约酒精、缩小包装。在有关单位的协助下,我们完成了浓缩剂的研究。
I. Introduction At present, the vast majority of domestic mosquito-killing propellants use alcohol as a solvent. Due to the shortage of alcohol source and the rising price, the cost of the solvent for the mosquito-killing propellant exceeds the cost of the original drug. Meanwhile, indoor spraying of alcohol destroys the ground, walls and furniture. Finishes. Therefore, in recent years, many units began to use water as a solvent for alcohol research, and also products come out, but the pyrethroid products in the water can not be long-term stability of the water as a solvent can not be long-term storage, and water products packaging large transport Very inconvenient. If you use concentrate formulations, you can save a lot of alcohol, reduce packaging. With the help of the relevant units, we completed the study of concentrates.
