pvc乳液聚:早的工業(yè)生產(chǎn)pvc的一種。在乳液聚合中,,除水和單體外,,還要加入磺酸鈉等表面活性劑作乳化劑,使單體分散于水相中而成乳液狀,,以水溶或過酸銨為引發(fā)劑,,還可以采用“氧化-還原”引發(fā)體系,聚合歷程和懸浮法不同,。也有加入聚醇作乳化劑醇作調(diào)節(jié)劑,,碳鈉作緩沖劑的。聚合有間歇法,、半連續(xù)法和連續(xù)法三種,。聚合產(chǎn)物為乳膠狀,乳液粒徑0.05~2μm,可以直接應(yīng)用或經(jīng)噴霧干燥成粉狀樹脂,。乳液聚的聚合周期短,,較易控制,的樹脂分子量高,,聚合度較均勻,,適用于作聚糊,制人造革或浸漬制品,。乳液法聚合的配方復(fù)雜,,產(chǎn)品雜質(zhì)含量較高。

as mentioned before, glass reinforced ppa resin has a high hdt value, which can tolerate short term effects of high temperature, for example, in a furnace,/in steam phase&in the process of infrared countercurrent consolidation. the thermal oxidation stability of ppa resin makes it capable of long-term high temperature effect&glass enhancement ppa. within 20000 hours, its continuous use temperature can reach 330 f.
