1982年以来,我们试用铁制发射器发射DDVP(敌敌畏)烟雾炮灭鼠,效果很好,现将试验结果报告如下。一.DDVP烟雾剂的制备将烤干的锯木屑2克,用喷雾器将80％DDVPlml喷至锯木屑上拌匀,立即用塑料口袋装好,胶圈套严,以防挥发。另取硝酸钾4克,木炭粉2克《硝酸钾和木屑、DDVP不能统装一个口袋,否则难以燃烧,将上述药物拌匀后装炮,插入引捻,待点火。二.发射器:无缝钢管长约13cm,内径2
Since 1982, we have experimented with iron launchers emitting DDVP (dichlorvos) smoke guns rodent control, the effect is very good, the test results are reported as follows. I. Preparation of DVVP Aerosols 2 grams of dried sawdust, spray 80% DDVPlml sprayed with sawdust and mix well, immediately filled with plastic pockets, rubber ring sets to prevent evaporation. Another take 4 grams of potassium nitrate, charcoal powder 2 grams of “potassium nitrate and sawdust, DDVP can not hold a pocket, otherwise it is difficult to burn, mix the drugs after the cannon, insert the twist, to be ignited.” Two launchers: seamless steel pipe length of about 13cm, diameter 2
