Ngolo yovala hotelo - ngolo ya Bonasi (wamalonda wovomerezeka) - mtengo wangolo ya hotelo

Fiberglass yolimbitsa pulasitiki, yomwe imadziwika kuti FRP, yomwe ndi pulasitiki yowonjezeredwa ndi fiberglass.Ndi chinthu chophatikizika chokhala ndi ulusi wagalasi ndi zinthu zake (nsalu zamagalasi, lamba, zomverera, ulusi, ndi zina zotero) monga kulimbikitsa ndi kupanga utomoni ngati matrix.Ngolo yansalu yopangidwa ndi FRP ili ndi zabwino ndi zoyipa izi:
Ubwino: kulemera kopepuka, mphamvu yayikulu, kachulukidwe wachibale pakati pa 1.5-2.0, 1 / 4-1 / 5 yokha ya chitsulo cha kaboni, koma mphamvu yamakomedwe ili pafupi.Kulimba, kupindika ndi kukakamiza kwa epoxy FRP kumatha kufika kupitilira 400MPa.
FRP yolimbana ndi dzimbiri ndi zinthu zabwino zolimbana ndi dzimbiri, zomwe zimalimbana bwino ndi mlengalenga, madzi, kuchuluka kwa asidi, alkali, mchere, komanso mafuta osiyanasiyana ndi zosungunulira zosiyanasiyana.
Njirayi ndi yophweka, ndondomekoyi ndi yophweka, ndipo ikhoza kupangidwa nthawi imodzi, kuti mankhwalawa akhale ndi kukhulupirika kwabwino.
Zoipa: kusakhazikika bwino.The zotanuka modulus FRP ndi apamwamba kuposa zitsulo (E = 2.1 × 105) 10 nthawi yaing'ono, choncho nthawi zambiri amaona kuti kuuma sikokwanira ndi zosavuta kupunduka mu kapangidwe mankhwala.Kukana kutentha kwakukulu, FRP wamba sangathe kugwiritsidwa ntchito kwa nthawi yayitali pa kutentha kwakukulu.Pamene ambiri poliyesitala FRP ndi pamwamba 50 ℃ ndi ambiri epoxy FRP ndi pamwamba 60 ℃, mphamvu amachepetsa kwambiri.Kukalamba kosavuta ndi vuto lofala la mapulasitiki, ndipo FRP ndi chimodzimodzi.N'zosavuta embrittle ndi kuwonongeka pansi zochita za UV, mankhwala sing'anga ndi makina kupsyinjika.Zotsalira pambuyo pa kuchotsedwa kwa kuwononga chilengedwe ali ndi mlingo winawake wa kuipitsa chilengedwe.
