style="text-indent:25px">表面活性劑和合成洗滌劑形成一門工業(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60余年的發(fā)展，1995年世界洗滌劑總產(chǎn)量達(dá)到4300萬噸，其中肥皂900萬噸。據(jù)**預(yù)測，全世界人口從2000年到2050年將翻一番，洗滌劑總量將從5000萬噸增加到12000萬噸，凈增1.4培，這是一個令人鼓舞的數(shù)字。中國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310萬噸，僅次于美國，排名世界第二位。其中合成洗滌劑的生產(chǎn)量從1980年的40萬噸上升到1995年的230萬噸，凈增4.7倍，并以年平均增長率大于10%的速度增長。四川親水性發(fā)泡填充劑YM-305A是一種新一代發(fā)泡**碳?xì)浔砻婊钚詣?，適用于耐鹽發(fā)泡，發(fā)泡效果明顯優(yōu)于APG烷基糖苷。</p><div

style="text-indent:25px">發(fā)泡劑的實質(zhì)就是它的表面活性作用。沒有表面活性作用，就不能發(fā)泡，也就不能成為發(fā)泡劑，表面活性是發(fā)泡的關(guān)鍵。常用的表面活性劑類發(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）；3.松香皂類發(fā)泡劑；4．動植物蛋白類發(fā)泡劑；5．紙漿廢液等。廣義的發(fā)泡劑和狹義的發(fā)泡劑發(fā)泡劑有廣義與狹義兩個概念。這兩個概念是有一定的差別的，它可以區(qū)分非應(yīng)用性的發(fā)泡劑與應(yīng)用性發(fā)泡劑。廣義的發(fā)泡劑是指所有其水溶液能在引入空氣的情況下大量產(chǎn)生泡沫的表面活性劑或表面活性物質(zhì)。因為大多數(shù)表面活性劑與表面活性物質(zhì)均有大量的起泡的能力，因此，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)。因而，廣義的發(fā)泡劑的范圍很大，種類很多，其性能品質(zhì)相差很大，具有非常普遍的選擇性。</p><p style="text-indent:25px">表面活性劑的分類方法很多，根據(jù)疏水基結(jié)構(gòu)進(jìn)行分類，分直鏈、支鏈、芳香鏈、含氟長鏈等；根據(jù)親水基進(jìn)行分類，分為羧酸鹽、硫酸鹽、季銨鹽、PEO衍生物、內(nèi)酯等；有些研究者根據(jù)其分子構(gòu)成的離子性分成離子型、非離子型等，還有根據(jù)其水溶性、化學(xué)結(jié)構(gòu)特征、原料來源等各種分類方法。但是眾多分類方法都有其局限性，很難將表面活性劑合適定位，并在概念內(nèi)涵上不發(fā)生重疊。陽離子該類表面活性劑起作用的部分是陽離子，因此稱為陽性皂。其分子結(jié)構(gòu)主要部分是一個五價氮原子，所以也稱為季銨化合物。其特點是水溶性大，在酸性與堿性溶液中較穩(wěn)定，具有良好的表面活性作用和殺菌作用。YM-309發(fā)泡效果好，產(chǎn)生的泡沫豐富細(xì)膩、性能穩(wěn)定。</p><div

style="text-indent:25px">對于聚氧乙烯型非離子表面活性劑，溫度升高到一定程度時，溶解度急劇下降并析出，溶液出現(xiàn)混濁，這一現(xiàn)象稱為起曇，此溫度稱為曇點。這是因為聚氧乙烯與水之間的氫鍵斷裂，當(dāng)溫度上升到一定溫度時，聚氧乙烯可發(fā)生強(qiáng)烈脫水和收縮，使增溶空間減小，增溶能力下降。在聚氧乙烯鏈相同時，碳?xì)滏溤介L，濁點越低；在碳?xì)滏溝嗤瑫r，聚氧乙烯鏈越長則濁點越高。親水親油平衡值（HLB）：表面活性劑分子中親水和親油基團(tuán)對油或水的綜合親合力。根據(jù)經(jīng)驗，將表面活性劑的HLB值范圍限定在0-40，非離子型的HLB值在0-20。發(fā)泡劑較初形成的泡孔在不斷漲大，這是因為有更多的氣體擴(kuò)散并透過聚合物進(jìn)入了泡孔。北京發(fā)泡劑</p><p

style="text-indent:25px">發(fā)泡劑是用以使橡膠、塑料等分子材料發(fā)孔的一類物質(zhì)。它主要用于制備海綿制品，泡沫塑料和空心制品。原則上，凡不與高等分子材料發(fā)生化學(xué)反應(yīng)，并能在特定條件下產(chǎn)生無害氣體的物質(zhì)，都能用作發(fā)泡劑或發(fā)泡助劑。對發(fā)泡劑來說，總的要求是無毒或低毒，分解溫度適宜，易于在高的分子材料中分散及發(fā)孔率高等。發(fā)泡助劑的作用是降低發(fā)泡劑的分解溫度，幫助發(fā)泡劑分散，或提高發(fā)氣量。按化學(xué)組分，發(fā)泡劑和發(fā)泡助劑有無機(jī)和有機(jī)兩大類；按發(fā)泡劑所產(chǎn)生的氣體分，有氫氣和二氧化碳兩大類。目前，橡膠工業(yè)普遍采用的是有機(jī)類發(fā)泡制。四川親水性發(fā)泡填充劑</p><p
