style="text-indent:25px">凡是溶于水能夠明顯降低水的表面能的物質(zhì)稱為表面活性劑(surfaceactiveagent，SAA)或表面活性物質(zhì)。傳統(tǒng)觀念上認(rèn)為，表面活性劑是一類即使在很低濃度時(shí)也能明顯降低表（界）面張力的物質(zhì)。隨著對表面活性劑研究的深入，一般認(rèn)為只要在較低濃度下能明顯改變表（界）面性質(zhì)或與此相關(guān)、由此派生的性質(zhì)的物質(zhì)，都可以劃歸表面活性劑范疇。表面活性劑有天然的，如磷脂、膽堿、蛋白質(zhì)等，但更多的是人工合成的，如十八烷基硫酸鈉C18H37-SO3Na、硬脂酸鈉C17H35-COONa等。表面活性劑范圍十分普遍（陽離子、陰離子、非離子及兩性），為具體應(yīng)用提供多種功能，包括發(fā)泡效果，表面改性，清潔，乳液，流變學(xué)，環(huán)境和健康保護(hù)。物理發(fā)泡劑還能對菱鎂水泥起到一定的改性作用，降低產(chǎn)品返鹵泛霜的概率。遼寧發(fā)泡填充劑</p><p
