style="text-indent:25px">發(fā)泡劑的實(shí)質(zhì)就是它的表面活性作用。沒(méi)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(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）；3.松香皂類(lèi)發(fā)泡劑；4．動(dòng)植物蛋白類(lèi)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(gè)概念。這兩個(gè)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?yàn)榇蠖鄶?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(lèi)很多，其性能品質(zhì)相差很大，具有非常普遍的選擇性。陜西消防用發(fā)泡劑發(fā)泡劑當(dāng)聚合物粘度增加，泡孔不能再增長(zhǎng)時(shí)，泡沫就會(huì)穩(wěn)定住。</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(jiǎn)稱(chēng)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(wú)親水基）聚乙二醇HLB值=20（完全親水）。對(duì)陰離子表面活性劑，可通過(guò)乳化標(biāo)準(zhǔn)油來(lái)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(rùn)濕劑水/油乳化劑消泡劑。對(duì)非離子表面活性劑來(lái)說(shuō)，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(shí)的溫度稱(chēng)濁點(diǎn)。此時(shí)表面活性劑失去作用。濁點(diǎn)越高，使用的溫度范圍廣。</p><p

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(lèi)發(fā)泡劑效果較佳。其主要原因有兩個(gè)。一是由于所需發(fā)泡劑之量極大（有時(shí)達(dá)到基質(zhì)樹(shù)脂重量的20%或更多），而這類(lèi)發(fā)泡劑要比化學(xué)發(fā)泡劑便宜，這就補(bǔ)償了設(shè)備上的較高費(fèi)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(gè)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(lèi)和氯氟烴類(lèi)發(fā)泡劑，實(shí)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(shí)，熔體的粘度升高了，就可減少為穩(wěn)定泡沫所需的冷卻費(fèi)用。對(duì)于特低密度的泡沫塑料來(lái)說(shuō)，這一點(diǎn)尤其重要?；瘜W(xué)發(fā)泡劑應(yīng)容易分散均勻，能同塑料混熔者較好。陜西消防用發(fā)泡劑</p><p
