摘要
以辛硫磷、硫铵、磷酸二氢钾、氯化钾等为原料,采用挤条造粒技术制备0.3%辛硫磷药肥颗粒剂。对不同惰性的载体和肥料进行筛选,测试了所配制的药肥颗粒剂的各项指标以及热贮性能,结果都符合行业标准。确定了最终配方:辛硫磷0.3%,高岭土0.2%,硫铵71.5%,磷酸二氢钾12%,氯化钾10%,田箐粉4%,十二烷基苯磺酸钠2%。配方可为工业化生产提供依据。
The compound fertilizers with insecticide was prepared by extruded strip granulation with phoxim,sulphate,monopotassium phosphate and potash fertilizers as raw materials.Different inert carrier and fertilizers were selected and the various control indexes and heat storage performance for the medicinal fertilizer granules was investigated.The best formula was obtained:phoxim 0.3%,kaolin 0.2%,ammonium sulfate 71.5%,monopotassium phosphate 12%,potassium chlorate 10%,turnip powder 4%,sodium dodecyl benzene sulfonate 2%.
