Building, kawngkhar leh kawngkhar, pawn lam bang, inchung leh leiah chuan building-a energy hmanna hmun pawimawh pali a ni a, kawngkhar leh kawngkhar insulation erawh chu a chhe ber thung. China rama retaining parts tlangpui lam hawi chuan, kawngkhar leh kawngkharte energy hman dan chu bang atanga a let 4 vel, a chung aiin a let 5 vel a ni a, lei atanga a let 20 aia tam a ni a, retaining parts te energy hman zawng zawng atanga 40%~50% vel a ni. Chuvangin, kawngkhar leh kawngkharte thermal insulation performance tihsan, kawngkhar leh window-a energy hman tlem hi indoor thermal environment quality tihsan leh building energy saving level tihsan nan link pawimawh tak a ni. Application-a composite materials lo chhuahna hian ngaihtuahna thar min rawn thlen a, chu chuan energy-saving door leh window-te inthlak danglamnaah a hmang thei ta a ni. Polyurethane pull extrusion window frame, traditional materials nena khaikhin chuan a size stability a chak zawk a, transverse mechanical property sang zawk a nei a, specific strength leh rigidity sang zawk a nei a, heat insulation effect a nei tha zawk bawk. Polyurethane material technology hmanga pull leh extrusion process danglam tak bakah hian he material hian mechanical volatile matter (VOC) a keng tel lo a, chuvangin boruak tichhe lo tak a ni bawk. Glass Fiber Reinforced polyurethane extrusion door leh window profile, chu glass fiber hmanga siam a ni a, chu chu reinforcing material atan, polyurethane chu matrix atan, advanced injection immersion rubber extrusion process hmangin a ni. GRPU kawngkhar leh window profile siam chu building sang tak tak tan K 2.0 W / (MK) total heat transfer coefficient hmanga energy-saving window solution pek a ni. Polyurethane (PU) hian innate heat insulation ability a nei a, energy saving doors leh Windows industry-ah hian foam sealant siam nan hun rei tak an lo hmang tawh a, sealing strip, heat insulation strip, polyurethane hmangin energy saving window frame pumpui siam nan an hmang a, hei hi China rama hmasa ber a ni. GRPU window frame thatna chu GRPU material ngeia performance characteristics atanga teh a ni. Composite material chi thar a nih angin GRPU hi a thanlenna hmun thar a ni. He resin hmang hian profile lian zawk, thinner leh chak tawk tak i siam thei a, window frame lian tak leh curtain wall thlengin hman a ni. Aluminum, thing leh plastic aiin an tha zawk hle niin an sawi. Expansion tha tak leh contraction performance tha tak neiin, climatic condition hrang hrang a tuar thei a, Arctic khaw lum atanga thlaler khaw lum leh tuipui kama hnim thlengin a tuar thei bawk. A paint theih a, a hnuah pawh a process theih a, thing ang maia lang thei a ni. Polyurethane Composite Window Frame hian a hnuaia thil pawimawh ber berte hi a nei a: Heat insulation sang GRPU profile leh solid wood, PVC hian thermal conductivity a nei tlem hle a, room temperature-ah 0.22 W / MK a nei a, aluminum alloy 1 / 700 vel chauh a ni a, heat insulation material tha tak a ni. Low thermal expansion GRPU-a linear thermal expansion coefficient chu 710-6 / K vel a ni a, hei hi aluminum alloy aiin a hniam zawk hle a, wall-a linear thermal expansion coefficient nen a inang hle. Chuvangin, temperature a inthlak chuan GRPU material frame chuan wall nen gap a siam lo ang a, temperature danglamna lian tak nei environment-a window pumpui heat insulation a tichiang ang. Corrosion resistant GRPU profile te hian acid tam zawk, alkali, chi, organic matter, tuifinriat tui, boruak lum lutuk te lakah corrosion resistance chak tak an nei a; Tin, rust immortality a awm lo, corrosion resistance hi material door leh window profile dang aiin a tha zawk. A bik takin tuipui kama awm, corrosive, leh generally wet places atan a tha hle. GRPU profile hi electromagnetic wave nei lo leh radio wave lantir thei insulating material tha tak a ni a; Communication system building-te hmanna bik a nei a ni.2) Polyurethane / Glass Fiber Composite Material
