(一)试制经过情况:关于六六六烟雾剂的处方,开始时我们以木屑代替了木香,氯酸钾代替了硝酸钾,白糖代替了硫脲,以后又用麸皮代替了白糖。我们在第一处方拟定后,进行了效果测定,发烟观察,燃烧时间和温度的测量及残渣重量测定。经过实地试用,我们认为以麸皮、氯酸钾、木屑、可湿性六六六这一组比较满意。主要的是以木屑代替了木香,麸皮代替了硫脲和白糖,降低了成本,简化了操作过程。现将几种处方列表如下:
(A) trial after the situation: on the BHC aerosol formulations, we started with wood instead of woody, potassium chlorate instead of potassium nitrate, sugar instead of thiourea, and later replaced with sugar bran. After the first prescription was drafted, we performed performance measurement, smoke observation, measurement of burning time and temperature, and determination of residue weight. After a field trial, we believe that the bran, potassium chlorate, wood chips, wettability six six six this group is more satisfied. Mainly wood instead of wood, wheat bran instead of thiourea and sugar, reducing costs and simplify the operation process. Now a few prescriptions are as follows:
