style="text-indent:25px">偶氮二碳酸胺大多數(shù)主要工業(yè)用熱塑性塑料的加工溫度，其范圍如上所述。大部分聚烯烴類、聚氯乙烯類和苯乙烯類熱塑性塑料的加工溫度范圍在300－410°F。對(duì)于這類塑料，有一種發(fā)泡劑使用可靠，就是偶氮二碳酸胺，又稱偶氮雙甲酸胺，或簡(jiǎn)稱AZO或AZ。在純凈狀態(tài)時(shí)，它是一種黃色／橙色粉末，大約在390°F開始分解，分解時(shí)產(chǎn)氣量為220cc／g，所產(chǎn)氣體主要為氮?dú)夂虲O，并帶有少量CO2，在某些條件下也含有氨。其固體分解產(chǎn)物是米色的，它不*可作為表明完全分解的指示劑，而且對(duì)發(fā)泡的塑料的顏色也無(wú)不良影響。較早的化學(xué)發(fā)泡劑（大約在1850年）是簡(jiǎn)單的無(wú)機(jī)碳酸鹽和碳酸氫鹽。浙江高溫發(fā)泡填充劑</p><p

style="text-indent:25px">發(fā)泡劑的實(shí)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(dòng)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(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，種類很多，其性能品質(zhì)相差很大，具有非常普遍的選擇性。浙江高溫發(fā)泡填充劑</p><p
