Abstract: An ambient temperature curable hydrophilic PU oligomer includes a PU pre-polymer having a hydrophilic center group and a curable terminated group. The ambient temperature curable hydrophilic PU oligomer includes the moisture-curable hydrophilic PU oligomer such as isocyanate-terminated PU pre-polymer and free-radical curable hydrophlic PU oligomer. The isocyanate-terminated PU pre-polymer is synthesized by mixing at least one multi-isocyanate, at least one polyol and one or more diol monomer with hydrophilic group. The acrylate-terminated PU oligomer is synthesized by adding 2-hydroxyethyl methacrylate (HEMA) into the isocyanate-terminated hydrophilic PU pre-polymer. Either acrylate- or isocyanate-terminated PU oligomer can be applied on a textile or a glass surface with a thin-layer coating technology. The curing reactions of these hydrophilic thin-layer coatings are carried out with moisture or UV-radiation, respectively, at ambient temperature.

Abstract: The invention related to an overlap of one pair of semicircles for the folding combining structure, wherein it have several yarn frame structure groups to one-way open or two-way open and one-way close or two-way close between left frame and right frame, and its characteristic lies in: Even rounds-lack overlap post consists of the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, among round-lack connected post insert in the left directional round-lack terminal surface plate and right directional round-lack terminal surface plate, and join the yarn frame structure group, so, can form several screen windows and rotate the two-way opening and closing or unilateral state that open and closing between the left frame of the window frame and right frame, in order to reach the theft-proof result of screen window.

Abstract: The invention related to an overlap one pair of semicircles for the folding typhoon defense combining structure, and it has installed several pieces of defend typhoon structure body between the left frame and the right frame of the window, its characteristic lies in: Defend structure body and include several even rounds-lack overlaps post, several even round-lack head defend typhoon board and two upright posts to make up, and the terminal surface of left frame and right frame have round-lack seat in order to join even round-lack head defend typhoon board, so, an overlap one pair of semicircles for the folding typhoon defense combining structure of the present invention is between the left frame and right frame, can form a result of effective dyke.
