消灭蚊蝇是部队卫生防疫工作重点之一。二二三的油剂与乳剂虽有一定的效能,但配制繁杂,成本较高,使用时需要较多的人力、工具、时间,同时又不适用于铁制工具,此外用量大,供应亦有问题。我们根据中级医刊1957年3月号上陈龐报告的六六六烟熏锭,加以改进,结果证明效果良好,且成本更低。按陈氏的六六六烟熏锭的配方为:六六六原粉(或可湿性六六六粉)37 .5%土硝 47%(化工原料公司购得)淀粉 14%重铬酸钾(粗制) 1.5%(化工原料公司购得)因为我们地区买不到土硝,故我们改用硝酸钾代替土硝,经试验其效果尚满意。我们的配方为:可湿性六六六粉 60.0克硝酸钾 24.5克淀粉 14.0克重铬酸钾(粗制)1.5克配法:将上远四种原料研碎放在一盛器内充分的拌匀,然后加水搅拌,待能用手揑合为度,随即
Elimination of mosquitoes and flies is one of the key points of the health and epidemic prevention work of the armed forces. Although Erzhong Oil and Emulsion has a certain efficiency, it is complicated and costly to prepare. It requires a lot of manpower, tools and time while it is not suitable for iron tools. In addition, problem. Based on the 666 smoked cigarettes reported by Chen Pang in the March 1957 issue of Intermediate Medicine, we improved the results and proved that the effect was good and the cost was lower. According to Chen’s six six six smoked ingot formula: six six six original powder (or wet six six six powder) 37 .5% soil nitrate 47% (chemical raw materials company) starch 14% potassium dichromate (Crude) 1.5% (purchased from Chemical Materials Company) Because we can not buy soil nitrate in our area, we use potassium nitrate instead of soil nitrate. The result is satisfactory. Our formula is: wettable six six six powder 60.0 grams of potassium nitrate 24.5 grams of starch 14.0 grams of potassium dichromate (crude) 1.5 grams with law: the far four kinds of raw materials on the ground in a blender and mix well , Then add water and stir until ready to hand kneading degree, then
