vinyl acrylate 中文意思是什麼
-
The effects of poly ( vinyl alcohol ) ( pva ), poly ( vinylpyrrolidone ) ( pvp ), sodium alginate ( sa - na ) and poly ( sodium acrylate ) ( pa - na ), blended with sodium carboxymethyl cellulose ( cmc ) respectively, on the suspension stability of graphite were studied
由於pva 、 pvp大分子的熵彈性和滲透壓效應，能改善懸浮液穩定性。 sa - na 、 pa - na還具有靜電排斥的機理，因此，比pva 、 pvp更能顯著地改善石墨懸浮液的分散性與穩定性。 -
The dispersity and stability of the graphite aqueous suspensions was investigated with centrifugation, the violet visible spectrophotometer, the laser particle size analyzer and scanning electron microscopy ( sem ). the following aspects of the production technique were carefully studied : 1. the effects of surfactants, poly ( vinyl alcohol ) ( pva ), poly ( vinyl pyrrolidone ) ( pvp ), sodium alginate ( sa - na ) and poly ( sodium acrylate ) ( pa - na ) on the suspension stability of graphite were investigated
本研究的主要內容有以下三個方面: 1 、研究了陰離子表面活性劑、非離子表面活性劑、聚乙烯醇（ pva ） 、聚乙烯基吡咯烷酮（ pvp ） 、海藻酸鈉（ sa - na ） 、聚丙烯酸鈉（ pa - na ）對石墨在水中分散性和穩定性的影響; 2 、研究了分散方法、分散介質、 ph值及羧甲基纖維素鈉（ cmc ）含量對石墨在水中分散性和穩定性的影響; 3 、研究了聚乙烯醇（ pva ） 、聚乙烯基吡咯烷酮（ pvp ） 、海藻酸鈉（ sa - na ） 、聚丙烯酸鈉（ pa - na ）四種助分散劑與羧甲基纖維素鈉（ cmc ）復配對石墨在水中分散性和穩定性的影響。 -
Poly butyl acrylate ( pba ) / mmt composites were prepared by emulsion polymerization. then, pvc / ( pba - mmt ) nanocomposites were prepared by suspension polymerization of vinyl chloride in the presence of pba / mmt composites
利用乳液聚合的方法制備了聚丙烯酸丁酯（ pba ）無機mmt復合膠乳，並在pba mmt復合膠乳存在下，採用懸浮聚合法制備了pvc （ pba - mmt ）納米復合材料。
