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，河北低溫發(fā)泡填充劑，或提高發(fā)氣量。按化學(xué)組分，發(fā)泡劑和發(fā)泡助劑有無機和有機兩大類；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，河北低溫發(fā)泡填充劑，河北低溫發(fā)泡填充劑，橡膠工業(yè)普遍采用的是有機類發(fā)泡制。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，具有非常多的選擇性。河北低溫發(fā)泡填充劑</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．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。天津固體發(fā)泡填充劑動物性水泥發(fā)泡劑以精選的動物(牛、羊)角質(zhì)蛋白為主要原材料。</p><div
