style="text-indent:25px">表面活性劑和合成洗滌劑形成一門(mén)工業(yè)得追溯到本世紀(jì)30年代，以石油化工原料衍生的合成表面活性劑和洗滌劑打破了肥皂一統(tǒng)天下的局面。經(jīng)過(guò)60余年的發(fā)展，1995年世界洗滌劑總產(chǎn)量達(dá)到4300萬(wàn)噸，其中肥皂900萬(wàn)噸。據(jù)**預(yù)測(cè)，全世界人口從2000年到2050年將翻一番，洗滌劑總量將從5000萬(wàn)噸增加到12000萬(wàn)噸，凈增1.4培，這是一個(gè)令人鼓舞的數(shù)字。中國(guó)的表面活性劑和合成洗滌劑工業(yè)起始于50年代，盡管起步較晚，但發(fā)展較快。1995年洗滌用品總量已達(dá)到310萬(wàn)噸，僅次于美國(guó)，排名世界第二位。其中合成洗滌劑的生產(chǎn)量從1980年的40萬(wàn)噸上升到1995年的230萬(wàn)噸，凈增4.7倍，并以年平均增長(zhǎng)率大于10%的速度增長(zhǎng)。黑龍江防水發(fā)泡劑廣義的發(fā)泡劑包含了大多數(shù)表面活性劑與表面活性物質(zhì)。</p><div

style="text-indent:25px">表面活性劑通常分為四大類(lèi)：陰離子，陽(yáng)離子，非離子和兩性離子（雙電子）。表面活性劑系統(tǒng)的熱動(dòng)力學(xué)很重要，不論是理論上還是實(shí)踐上。因?yàn)楸砻婊钚詣┫到y(tǒng)表示的是介于有序和無(wú)序物質(zhì)狀態(tài)之間的系統(tǒng)。表面活性劑溶液可能含有有序相（膠束）和無(wú)序相（自由表面活性劑分子和/或離子）。膠束——表面活性劑分子的親脂尾端聚于膠束內(nèi)部，避免與極性的水分子接觸；分子的極性親水頭端則露于外部，與極性的水分子發(fā)生作用，并對(duì)膠束內(nèi)部的憎水基團(tuán)產(chǎn)生保護(hù)作用。形成膠束的化合物一般為兩親分子，因此一般膠束除可溶于水等極性溶劑以外，還能以反膠束的形式溶于非極性溶劑中。</p><p style="text-indent:25px">由于液體蒸發(fā)是一個(gè)吸熱過(guò)程，因而用揮發(fā)性物理發(fā)泡劑時(shí)體系溫度容易控制，可防止聚合物的熱降解，避免中心燒焦，有利于制得較厚的發(fā)泡體．常用的揮發(fā)性發(fā)泡劑品種有：含5～7個(gè)碳的脂肪烴；鹵代烴；低沸點(diǎn)的醇，醚、酮和芳烴。在物理發(fā)泡劑中，氯氟烴(CFC)由于對(duì)臭氧層的破壞而受到限制。目前，用以部分替代CFC的物理發(fā)泡劑主要是二氯甲烷、甲基氯仿等．雖然它們的應(yīng)用可以減小CFC的用量，但仍不能徹底根除CFC對(duì)臭氧層的破壞，況且甲基氯仿對(duì)臭氧層也有一定的破壞作用，而極易燃燒，使用不安全，因此，對(duì)于實(shí)現(xiàn)完全不用CFC等對(duì)臭氧層破壞的物質(zhì)的較終目標(biāo)來(lái)說(shuō)，任重而道遠(yuǎn)．通常應(yīng)用物理發(fā)泡劑的工程塑料主要有ABS和酚醛樹(shù)脂等。常用的表面活性劑類(lèi)發(fā)泡劑有：1．十二烷基硫酸鈉（K12）；2．脂肪醇聚氧乙烯醚硫酸鈉（AES）。</p><div
