| Summary: | 碩士 === 朝陽科技大學 === 應用化學系碩士班 === 97 === This experimental choice tech：Pencycuron in field have DP(Dustable powder)、SC(Suspension concentrate)、WP(Wettable powder) and so on three kind of formulations. Difenoconazole in field have EC(Emulsifiable concentrate)、SC(Suspension concentrate)、WG(Water dispersible granules) and so on three kind of formulations.For the friendliness environment nowadays employs the formulation. Promotion medicament and save labor.Test Pencycuron preparation SC(Suspension concentrate) and Difenoconazole preparation ME(Micro- emulsion) and EW(Emulsion, oil in water). Distinction test SC(Suspension concentrate) with ME(Micro- emulsion) preparation SE(Suspo-Emulsion) and SC(Suspension concentrate) with EW(Emulsion, oil in water) preparation SE(Suspo-Emulsion).
ME(Micro- emulsion) and EW(Emulsion, oil in water) mixes matches non-ionic surfactant,and test hydrophilic-lipophilic balance. Observation effective component. In room temperature and heat-resisting under rate of dissociation and appearance. The operation changes including hydrophilic-lipophilic balance and surfactant.In SC(Suspension concentrate) with ME(Micro- emulsion) preparation SE(Suspo-Emulsion) rate of dissociation 2.16% and 1.62%,less than 5%.
Result demonstration particle size analysis chart. SC(Suspension concentrate) with EW(Emulsion, oil in water) preparation SE(Suspo-Emulsion) the particle size is 27.795
