| 摘 要： | 采用热重法、导数热重法和差热分析法,分别对基料凹凸棒、主效成分氯苯胺灵和抑芽粉剂进行热分析测定,通过对热分析结果的比较,提出了基料凹凸棒对主效成分氯苯胺灵的缓释机理。结果表明,经过液化工艺将氯苯胺灵附载到凹凸棒上,由于基料凹凸棒的比表面积较大,吸附在凹凸棒上的氯苯胺灵因表面效应在较低的温度下也易于挥发,并延缓了挥发速率,为选用凹凸棒作为基料对氯苯胺灵的缓释提供了理论依据。

| Abstract: | In this research,base-powder clay,chlorpropham and potato sprout inhibitor were determined by thermogravimetry(TG),derivative thermogravimetry(DTG) and differential thermal analyses(DTA),respectively.And the slow-release mechanism of chloropropham in potato sprout inhibitor was put forward by comparisons.It was concluded that when chlorpropham was carried on the clay by colliquative technology,chlorpropham absorbed on the clay could easily evaporate even at low temperature due to the clay's large specific surface area,and be slowed down for the rate of volatilization,which suggested that the clay could be used as base-powder for chlorpropham's slow-release. |
