復合乳化劑對于(yu)提高乳液穩定的重要性

　　復合乳化劑對于提高乳液穩(wen)定的重要性(xing)主要表現在以下幾(ji)點：

　　一、HLB值(zhi)乳(ru)(ru)化(hua)(hua)劑(ji)必須較強乳(ru)(ru)化(hua)(hua)能(neng)力(li),評定(ding)種乳(ru)(ru)化(hua)(hua)能(neng)力(li)標準乳(ru)(ru)化(hua)(hua)劑(ji)HLB值(zhi).表(biao)示乳(ru)(ru)化(hua)(hua)劑(ji)親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)親(qin)(qin)水(shui)基(ji)(ji)(ji)(ji)間力(li)量平衡關系(xi).HLB值(zhi)=7+Σ（親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)）+Σ（親(qin)(qin)水(shui)基(ji)(ji)(ji)(ji)）根據乳(ru)(ru)化(hua)(hua)劑(ji)HLB值(zhi)表(biao)查詢由于瀝青(qing)HLB值(zhi)般(ban)8~18,用于瀝青(qing)乳(ru)(ru)化(hua)(hua)劑(ji)HLB值(zhi)應該近范(fan)圍宜(yi).作乳(ru)(ru)化(hua)(hua)瀝青(qing)乳(ru)(ru)化(hua)(hua)劑(ji)親(qin)(qin)水(shui)基(ji)(ji)(ji)(ji),親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)數(shu),與水(shui)連(lian)(lian)接,與瀝青(qing)脫離(li)(li)；乳(ru)(ru)化(hua)(hua)劑(ji)親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)數(shu),親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)數(shu),與瀝青(qing)連(lian)(lian)接,與水(shui)脫離(li)(li).親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)與親(qin)(qin)水(shui)基(ji)(ji)(ji)(ji)適宜(yi),乳(ru)(ru)化(hua)(hua)劑(ji)便瀝青(qing)水(shui)相連(lian)(lian)接起(qi).說(shuo)許帶親(qin)(qin)油(you)(you)基(ji)(ji)(ji)(ji)親(qin)(qin)水(shui)基(ji)(ji)(ji)(ji)結構表(biao)面(mian)性劑(ji)能(neng)作用乳(ru)(ru)化(hua)(hua)劑(ji),尤(you)其能(neng)作瀝青(qing)乳(ru)(ru)化(hua)(hua)劑(ji).,瀝青(qing)標號(hao)與發(fa)變化(hua)(hua),定(ding)要(yao)重新(xin)配乳(ru)(ru)化(hua)(hua)劑(ji)品(pin)種及用量。

　　二(er)、ξ電(dian)位值各種(zhong)乳化(hua)劑(ji)制瀝青(qing)(qing)乳液性能,檢(jian)測(ce)其ξ電(dian)位值具重要意義.ξ電(dian)位值越,乳化(hua)瀝青(qing)(qing)微粒間相互排(pai)斥(chi)力越,乳液穩定性越,且瀝青(qing)(qing)微粒所(suo)帶離(li)電(dian)荷強,與骨料粘附性。

　　三、離(li)(li)特性乳(ru)(ru)化(hua)劑(ji)(ji)根(gen)據電荷陽(yang)離(li)(li)、陰(yin)(yin)離(li)(li)、非離(li)(li)型乳(ru)(ru)化(hua)劑(ji)(ji).道路(lu)施(shi)工(gong)(gong),由于選(xuan)擇集料(liao)種(zhong)類(lei)同,乳(ru)(ru)化(hua)劑(ji)(ji)要作(zuo)調整.安山(shan)巖、輝(hui)綠巖等二氧(yang)化(hua)硅含(han)(han)量(liang)較(jiao)高,碳(tan)酸鈣含(han)(han)量(liang)較(jiao)低,耐酸性較(jiao),石料(liao)般帶負電荷、所選(xuan)用陽(yang)離(li)(li)型乳(ru)(ru)化(hua)劑(ji)(ji)產(chan)乳(ru)(ru)化(hua)瀝(li)青集料(liao)粘附(fu)性較(jiao).于石灰巖集料(liao),采(cai)用陽(yang)離(li)(li)乳(ru)(ru)化(hua)劑(ji)(ji)制(zhi)(zhi)作(zuo)乳(ru)(ru)化(hua)瀝(li)青,石灰石集料(liao)腐蝕性,并放二氧(yang)化(hua)碳(tan)發泡,影響鋪路(lu)質量(liang),必(bi)須選(xuan)用陰(yin)(yin)離(li)(li)乳(ru)(ru)化(hua)劑(ji)(ji)制(zhi)(zhi)作(zuo)乳(ru)(ru)化(hua)劑(ji)(ji)制(zhi)(zhi)作(zuo)乳(ru)(ru)化(hua)瀝(li)青.施(shi)工(gong)(gong),選(xuan)用何種(zhong)離(li)(li)乳(ru)(ru)化(hua)劑(ji)(ji)制(zhi)(zhi)作(zuo)乳(ru)(ru)化(hua)瀝(li)青,應根(gen)據工(gong)(gong)程要求定。

　　四、根據裂(lie)(lie)速度(du)選擇瀝(li)(li)青(qing)路面(mian)(mian)鋪(pu)(pu)筑,施工性能需要,乳化(hua)瀝(li)(li)青(qing)提許特殊要求(qiu).例(li)修筑貫入(ru)式瀝(li)(li)青(qing)路面(mian)(mian),噴灑完(wan)全裂(lie)(lie)凝固要求(qiu)間(jian)較短(duan),防集料(liao)及(ji)吸附(fu)流(liu)失,造鋪(pu)(pu)筑瀝(li)(li)青(qing)路面(mian)(mian)黏附(fu)性差,路面(mian)(mian)松散,強(qiang)度(du)低,要求(qiu)選用乳化(hua)瀝(li)(li)青(qing)裂(lie)(lie)速度(du)要快、凝結快.根據路面(mian)(mian)鋪(pu)(pu)筑施工要求(qiu),選擇裂(lie)(lie)速度(du)適宜乳化(hua)劑,產(chan)適宜裂(lie)(lie)速度(du)乳化(hua)瀝(li)(li)青(qing)。

　　五、根據瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)組特性(xing)(xing)(xing)(xing)選擇(ze)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)材料組同,乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)要(yao)求相(xiang)同,每種乳(ru)(ru)(ru)化(hua)劑(ji)定(ding)類型(xing)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)效.般講,于(yu)少(shao)芳(fang)香(xiang)(xiang)族富環烷烴(jing)石油瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),直鏈烷烴(jing)乳(ru)(ru)(ru)化(hua)劑(ji)效；芳(fang)香(xiang)(xiang)烴(jing)含量占優(you)勢(shi)石油瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),高(gao)環烷烴(jing)鈉皂比(bi)(bi)較效；于(yu)高(gao)芳(fang)烴(jing)結構化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),用芳(fang)香(xiang)(xiang)環乳(ru)(ru)(ru)化(hua)劑(ji)比(bi)(bi)較理想.乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)極(ji)(ji)性(xing)(xing)(xing)(xing)較,則要(yao)求親水(shui)性(xing)(xing)(xing)(xing)極(ji)(ji)強乳(ru)(ru)(ru)化(hua)劑(ji),才(cai)(cai)能穩(wen)(wen)定(ding)乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)；相(xiang)反,若乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)極(ji)(ji)性(xing)(xing)(xing)(xing)較或(huo)極(ji)(ji)性(xing)(xing)(xing)(xing),則要(yao)求親油性(xing)(xing)(xing)(xing)極(ji)(ji)強乳(ru)(ru)(ru)化(hua)劑(ji),才(cai)(cai)能獲穩(wen)(wen)定(ding)乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing).聚合物(wu)改性(xing)(xing)(xing)(xing)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)、煤焦油瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),選用極(ji)(ji)性(xing)(xing)(xing)(xing)機乳(ru)(ru)(ru)化(hua)劑(ji)或(huo)機膠(jiao)(jiao)體乳(ru)(ru)(ru)化(hua)劑(ji),獲穩(wen)(wen)定(ding)機膠(jiao)(jiao)體乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing).瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)存機酸(suan)含量太(tai)低,足使苛性(xing)(xing)(xing)(xing)堿溶(rong)液制造(zao)快(kuai)裂型(xing)乳(ru)(ru)(ru)化(hua)瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)添(tian)加表面性(xing)(xing)(xing)(xing)酸(suan)類物(wu)質(zhi),用改善乳(ru)(ru)(ru)化(hua)性(xing)(xing)(xing)(xing)質(zhi).用高(gao)溫(wen)空(kong)氣氧化(hua)重油瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing),比(bi)(bi)用蒸汽蒸餾或(huo)真(zhen)空(kong)蒸餾瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)具(ju)較乳(ru)(ru)(ru)化(hua)性(xing)(xing)(xing)(xing)。六、乳(ru)(ru)(ru)化(hua)劑(ji)結構乳(ru)(ru)(ru)化(hua)劑(ji)親油基碳氫(qing)鏈及其(qi)支(zhi)鏈直接(jie)影(ying)響親油基親瀝(li)(li)(li)(li)(li)青(qing)(qing)(qing)(qing)能力。
