中文拼音 [zēngshuǐjì]
憎水劑
英文
hydrophober-
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。According to the feature that deformation resulted from water absorption and mildew appear mainly on the rabbet surface of ccf, this paper adopts rsst to spray a special waterproof sealant on rabbet surface of ccf, so that the sealant can get into fiberboard to certain extent by means of capillarity and penetration, blockage the holes between fibers and capillary, cut up passage of water and change the properties of soakage and sorption to water in capillarity and fiber. at the same time, solidified sealant can form a compact waterproof pellicle on rabbet surface so as to prevent water and humidity from fiber ' s expansion and mildewing
針對吸水變形、霉變主要發生在地板企口表面的特徵，採用企口表面全封閉法，在復合強化地板企口表面噴塗特殊的防水封閉劑，使其依靠毛細管作用及滲透作用進入板內一定深度，堵塞木纖維之間的空隙及毛細孔通道，截斷水分傳遞的渠道，並改變毛細孔壁及纖維的表面性質以不利於水的浸潤與吸附，同時其固化后能在企口表面形成一層緻密的憎水薄膜，防止水分、濕氣從企口侵入板內引起木纖維膨脹變形、發霉等現象。The epoxy resin modified by polysiloxane have the advantage of both polysiloane and epoxy resin, it have good heat - resistance, moisture - resistance, dielectric properties. to improve the heat - resistance and the strengthening of the composite, nano - sio2 has been add into the reaction system to modify the epoxy resin with polysiloxane
