的條件下，乙烯于管式反應(yīng)器中連續(xù)聚合可以得到低相對(duì)分子質(zhì)量聚乙烯；②裂解法，中國(guó)臺(tái)灣蠟供應(yīng)公司，在一定的溫度下。高相對(duì)分子質(zhì)量聚乙烯可以分解得到低相對(duì)分子質(zhì)量聚乙烯；③

style="text-indent:25px">乳化蠟及其應(yīng)用乳化蠟是多相分散體系，一般制備的乳化蠟是微小的蠟粒分散于水中，這種乳化蠟稱為水包油型乳化蠟(O／W)。若水在內(nèi)相而蠟在外相則稱為油包水型乳化蠟(W／O)。分散相粒徑一般小于I．5Ⅲ 。乳化蠟配方中主要包括各種蠟類、油類、乳化劑，各種添加劑和水。常用的乳化劑有陽離子乳化劑、陰離子乳化劑和非離子乳化劑。乳化蠟應(yīng)用領(lǐng)域相當(dāng)廣1泛，可以說量大面廣。其主要的應(yīng)用領(lǐng)域是紡織、造紙、皮革、纖維板、上光水果保鮮、建筑、園藝、陶瓷等方面。國(guó)外石蠟乳液的主要制造廠商有飛馬石油公司、香港飛馬石油公司等。1988年美國(guó)市場(chǎng)乳化蠟用量為190
