Kodi mapulasitiki olimbikitsidwa ndi fiberglass ndi chiyani?
Fiberglass yolimbitsa pulasitikindi chinthu chophatikizika chokhala ndi mitundu yambiri, katundu wosiyanasiyana, ndi ntchito zosiyanasiyana. Ndi chinthu chatsopano chopangidwa ndi utomoni wopangira ndi fiberglass kudzera munjira yophatikizika.

Mawonekedwe a pulasitiki yolimba ya fiberglass:
(1) kukana bwino kwa dzimbiri: Mtengo wa FRPndi zabwino dzimbiri zosagwira zipangizo, kwa mlengalenga; madzi ndi ambiri ndende zidulo ndi zamchere; mchere ndi zosiyanasiyana mafuta ndi zosungunulira ndi kukana zabwino, wakhala ankagwiritsa ntchito mbali zonse za dzimbiri mankhwala. Kodi m'malo carbon zitsulo; chitsulo chosapanga dzimbiri; matabwa; zitsulo zopanda chitsulo ndi zipangizo zina.
(2) Kulemera kochepa komanso mphamvu zambiri:Kachulukidwe wachibale wa FRP ali pakati pa 1.5 ~ 2.0, 1/4 ~ 1/5 yokha ya chitsulo cha kaboni, koma mphamvu yamakomedwe imakhala pafupi kapena kuposa ya chitsulo cha kaboni, ndipo mphamvuyo imatha kufananizidwa ndi chitsulo chapamwamba cha aloyi, chomwe chimagwiritsidwa ntchito kwambiri muzamlengalenga; zitsulo zothamanga kwambiri komanso zinthu zina zomwe zimafunika kuchepetsa kulemera kwake.
(3) zabwino zamagetsi:FRP ndichinthu chabwino kwambiri chotchingira chopangira ma insulators, ma frequency apamwamba amatha kukhalabe abwino.
(4) zabwino matenthedwe katundu:Mtengo wa FRPotsika madutsidwe, chipinda kutentha 1.25 ~ 1.67KJ yekha zitsulo 1/100 ~ 1/1000 ndi kwambiri matenthedwe kutchinjiriza zakuthupi. Pankhani ya kutentha kwambiri nthawi yomweyo, ndiye chitetezo choyenera chamafuta ndi zinthu zosagwirizana ndi dzimbiri.
(5) ntchito yabwino kwambiri:malinga ndi mawonekedwe a mankhwala kusankha ndondomeko akamaumba ndi njira yosavuta akhoza akamaumba.
(6) Mapangidwe abwino:zinthuzo zikhoza kusankhidwa mokwanira malinga ndi zofunikira kuti zikwaniritse zofunikira za ntchito ya mankhwala ndi kapangidwe.
(7) otsika modulus elasticity:modulus ya elasticity ya FRP ndi 2 nthawi zazikulu kuposa zamatabwa, koma 10 nthawi yaying'ono kuposa yachitsulo, choncho nthawi zambiri zimamveka kuti kulimba sikukwanira mu kapangidwe ka mankhwala, ndipo n'kosavuta kupunduka. Njira yothetsera, ikhoza kupangidwa kukhala chipolopolo chopyapyala; Mapangidwe a sangweji amathanso kupangidwa kudzera mu ulusi wapamwamba wa modulus kapena mawonekedwe a nthiti.
(8) Kusakhazikika kwa kutentha kwanthawi yayitali:wambaMtengo wa FRPsangathe kugwiritsidwa ntchito kwa nthawi yaitali pa kutentha, ambiri cholinga polyester utomoni FRP pa madigiri 50 pamwamba mphamvu adzakhala kwambiri yafupika.
(9) Zochitika zaukalamba:mu kuwala kwa ultraviolet; mphepo, mchenga, mvula ndi matalala; media media; kupsinjika kwamakina ndi zotsatira zina mosavuta kumabweretsa kuwonongeka kwa magwiridwe antchito.
(10) Mphamvu yometa ubweya wapakati:interlayer kukameta ubweya mphamvu amanyamulidwa ndi utomoni, choncho ndi otsika. N'zotheka kupititsa patsogolo mphamvu ya interlayer yomangirira posankha ndondomekoyi, pogwiritsa ntchito coupling wothandizira ndi njira zina, ndikupewa kumeta ubweya wa interlayer momwe mungathere popanga mankhwala.
