液化石油氣.丙烷丙烯丁烷丁烯及其混合物.要求The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm
本論文以開發無機?有機復合納濾膜為出發點,首先在al _ 2o _ 3多孔微濾膜上利用溶膠?凝膠法制備sio _ 2 al _ 2o _ 3無機復合超濾膜作為無機?有機復合納濾膜的基膜;選用聚乙烯醇和聚酰胺為表面功能層材料,分別探討了以羥基丁二酸和磺基水楊酸為混合交聯劑,採用浸塗法制備了聚乙烯醇sio _ 2 ? al _ 2o _ 3復合納濾膜;以均苯二甲酰氯、哌嗪和二胺為單體,採用界面聚合法制備了聚酰胺sio _ 2 ? al _ 2o _ 3復合納濾膜,並對影響膜性能的諸多因素進行系統研究。The substitution of pervaporation for traditional separation in organic mixtures is of energy - saving and environment - protecting significance. in this paper, pervaporation of two kinds of organic mixtures is investigated : one is using ca membrane and ca - eva ( ethylene - co - ethylene acetate ) composite membrane for methanol removal from mtbe ( methyl t - butyl ether ), focused on the influence of casting solvent mixtures ; the other is utilizing proper membrane stuff and additive to separate p - xylene from m - xylene
本文對兩類有機有機混合體系進行了滲透汽化膜過程的研究,其一為醋酸纖維素( ca )膜及ca -乙烯醋酸乙烯共聚物( eva )復合膜用於甲基特丁基醚( mtbe )中少量甲醇( 5 meoh )的脫除,探討鑄膜混合溶劑及后處理技術對膜分離性能的影響。其二為運用適當的膜材料及添加劑去除間二甲苯( mx )中的少量對二甲苯( 10 px ) 。Raw materials for the rubber industry. carbon black. evaluation of the quality of the carbon black in a styrene - butadiene based mixture
