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，山東聚氨脂發(fā)泡劑，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，山東聚氨脂發(fā)泡劑。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，山東聚氨脂發(fā)泡劑，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。物理發(fā)泡劑分為三類：①壓縮氣體；②可溶性固體：③在沸點低于0℃的揮發(fā)性液體。山東聚氨脂發(fā)泡劑</p><div

style="text-indent:25px">由于液體蒸發(fā)是一個吸熱過程，因而用揮發(fā)性物理發(fā)泡劑時體系溫度容易控制，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個碳的脂肪烴；鹵代烴；低沸點的醇，醚、酮和芳烴。在物理發(fā)泡劑中，氯氟烴(CFC)由于對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對臭氧層的破壞，況且甲基氯仿對臭氧層也有一定的破壞作用，而極易燃燒，使用不安全，因此，對于實現(xiàn)完全不用CFC等對臭氧層破壞的物質(zhì)的較終目標(biāo)來說，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和酚醛樹脂等。山東聚氨脂發(fā)泡劑有機發(fā)泡劑與無機發(fā)泡劑相反，可供選擇的有機化學(xué)發(fā)泡劑品種繁多，物理形態(tài)也各自不同。</p><div

style="text-indent:25px">表面活性劑要呈現(xiàn)特有的界面活性，必須使疏水基和親水基之間有一定的平衡。親水親油平衡值(Hydrophile-LipophileBalance)，簡稱H·L·B值，表示表面活性劑的親水疏水性能，如石蠟HLB值=0（無親水基）聚乙二醇HLB值=20（完全親水）。對陰離子表面活性劑，可通過乳化標(biāo)準(zhǔn)油來確定HLB值。HLB值可作為選用表面活性劑的參考依據(jù)。HLB值：15~1813~158~167~93.5~61.5~3。用途增溶劑：洗滌劑油/水型乳化劑潤濕劑水/油乳化劑消泡劑。對非離子表面活性劑來說，親水性取決于醚鍵的多少，醚與水分子的結(jié)合是放熱反應(yīng)。當(dāng)溫度上升，水分子逐漸脫離醚鍵，而出現(xiàn)混濁現(xiàn)象，剛剛出現(xiàn)混濁時的溫度稱濁點。此時表面活性劑失去作用。濁點越高，使用的溫度范圍廣。</p><p style="text-indent:25px">兩性離子這類表面活性劑的分子結(jié)構(gòu)中同時具有正、負(fù)電荷基團，在不同pH值介質(zhì)中可表現(xiàn)出陽離子或陰離子表面活性劑的性質(zhì)。表面活性劑由于具有潤濕或抗粘、乳化或破乳、起泡或消泡以及增溶、分散、洗滌、防腐、抗靜電等一系列物理化學(xué)作用及相應(yīng)的實際應(yīng)用，成為一類靈活多樣、用途普遍的精細(xì)化工產(chǎn)品。表面活性劑除了在日常生活中作為洗滌劑，其他應(yīng)用幾乎可以覆蓋所有的精細(xì)化工領(lǐng)域。在堿性水溶液中呈陰離子表面活性劑的性質(zhì)，具有很好的起泡、去污作用；在酸性溶液中則呈陽離子表面活性劑的性質(zhì)，具有很強的殺菌能力。發(fā)泡劑選用天然油脂制造，不含PFOA/PFOS，無毒，可完全生物降解，是綠色環(huán)保型產(chǎn)品。</p><div

style="text-indent:25px">為制成特低密度泡沫塑料（密度低至10lb/cu.ft.左右）采用氯氟烴和烴類發(fā)泡劑效果較佳。其主要原因有兩個。一是由于所需發(fā)泡劑之量極大（有時達(dá)到基質(zhì)樹脂重量的20%或更多），而這類發(fā)泡劑要比化學(xué)發(fā)泡劑便宜，這就補償了設(shè)備上的較高費用；二是與泡沫穩(wěn)定化的熱力學(xué)相關(guān)。正如本文前面談到的，要使一個泡沫穩(wěn)定化，必須在出現(xiàn)塌陷之前就得改變聚合物熔體的粘度。使用較普遍的烴類和氯氟烴類發(fā)泡劑，實際上可以降低它們所用于的聚合物的熔體粘度。當(dāng)它們發(fā)生汽化而脫離聚合物溶液時，熔體的粘度升高了，就可減少為穩(wěn)定泡沫所需的冷卻費用。對于特低密度的泡沫塑料來說，這一點尤其重要。廣義的發(fā)泡劑的發(fā)泡倍數(shù)（產(chǎn)泡能力）、泡沫穩(wěn)定性（可用性）等技術(shù)性能沒有嚴(yán)格的要求。山東聚氨脂發(fā)泡劑</p><p style="text-indent:25px">狹義的發(fā)泡劑就是工業(yè)實際應(yīng)用的發(fā)泡劑，一般人們常說的發(fā)泡劑就是指這類狹義發(fā)泡劑。山東聚氨脂發(fā)泡劑</p><p style="text-indent:25px">目前世界各國針對無氟發(fā)泡的相關(guān)應(yīng)對方案也有很大的區(qū)別，通常是由于每個國家基礎(chǔ)研究水平和工業(yè)發(fā)展水平差距較大，又對聚氨酯泡沫產(chǎn)品特定性能的要求也有所不同，故對CFC替代技術(shù)的研究、應(yīng)用側(cè)重點也不一致導(dǎo)致的。在聚氨酯工業(yè)發(fā)展的近百年中，一直采用一氟三氯甲烷（CFC-11）和二氟二氯甲烷（CFC-12）、三氯三氟乙烷CFC-113等作為發(fā)泡劑使用。CFC-11是低沸點化合物，室溫下為液體，低毒性，不易燃，與聚醚（酯）多元醇組分互融性優(yōu)良，沸點低（23.8℃）且適度。當(dāng)異氰酸酯和聚酯多元醇或聚醚多元醇反應(yīng)產(chǎn)生熱能時，即可使其汽化，產(chǎn)生大量氣泡，蒸汽熱導(dǎo)率低，是一種十分優(yōu)良的物理發(fā)泡劑。然而，近年來發(fā)現(xiàn)，該類化合物是破壞地球臭氧層的主要物質(zhì)，已經(jīng)被列入禁用化學(xué)品。因此，對于聚氨酯工業(yè)來說，尋找取代氯氟烴（CFC）類發(fā)泡劑的新品種是當(dāng)前聚氨酯工業(yè)發(fā)展的首要任務(wù)之一。山東聚氨脂發(fā)泡劑</p><p
