  1. 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。
  2. Firstly, the surface characteristic of polystyrene particle is changed from water detesting to water intimity by using special techniques and admixtures so mat the compound quality with inorganic materials is insured. secondly, the contradiction between the weight and strength is solved through optimizing the particle size and using composite fiber and the best heat conductivity is achieved under the condition that the necessary strength is met. in the research process, the author solved the problem of fiber dispersing in insulating materials so that the contraction of the material is controlled

    課題研究中，首先採用特殊的改性工藝及外加劑實現對聚苯乙烯顆粒表面的成功改性，使其表面由憎水轉化為完全親水，確保與無機材料的復合質量；其次，通過採用優化骨料級配及使用復合纖維等措施解決了保溫材料的輕質與強度的矛盾，使保溫材料在滿足必要的強度的前提下，導熱系數降至最小；並且，課題研究中成功解決了纖維在保溫材料中均勻分散的問題，達到了抑制保溫材料收縮的目的；最後，通過採用復合外加劑、合適的膠凝材料及合理的配比等措施確保該保溫材料具有良好的和易性，滿足施工的要求。
  3. First, the low profile performance of up / lpa / styrene system is governed by two critical steps : the phase separation and the microvoid formation. second, the cure of the low profile unsaturated polyester resin can be divided into four periods : induction, phase separation ( including spinodal decomposition and coalescence and growth ), gelation and microvoid formation

    指出:相分離以及微孔的形成是決定up田l隊/苯乙烯三相系統低收縮性能的關鍵，低輪廓不飽和聚醋樹脂的固化可以分成四個階段:引發、相分離（包含兩種類型:旋竹線分離以及合井與長大） 、凝膠和微孔形成。
