4、值為,反,,應(yīng)溫度為℃左右壁材配比為乙二胺溶液在內(nèi)勻速加入,反應(yīng)時間為。最后,采用單因素實驗討論了相比、芯壁比、乳化劑用量等因素對微膠囊釋放速率的影響并得出了比較適宜的反應(yīng)工藝條件。結(jié)果表明攪拌速度、乳化時間、乳化劑的用量和芯壁比對釋放速率有正影響,而相比油水、用量對釋放速率有負影響。反應(yīng)條件如下芯壁比為一,乳化劑一十二烷基酚聚氧,乙烯醚小于相比為一,聚,乙烯醇用量不超過攪拌速度不小于,乳化時間不小于。關(guān)鍵詞微膠囊制備分散染料聚酞胺釋放性能?1994-2009ChinaAcademicJournalElectronicPublishingHouse.Allrightsr
