'Denga lowala' la nyumba zamafakitale: FRP skylights

Chifukwa chomwe magetsi a FRP (fiberglass reinforced plastic) amatha kukhala "denga lowala" la nyumba zamafakitale ndikuti amakwaniritsa zofunikira zamafakitale pa-zowunikira zazikuluzikulu, kulimba kwambiri komanso kukhazikika, komanso kutsika mtengo wokonza. Amatha kuthana ndi zowawa zamawonekedwe achikhalidwe ndikuwongolera magwiridwe antchito a nyumba zamafakitale.

1. Kuthetsa zovuta zowunikira zanyumba zamafakitale

Nyumba zamafakitale nthawi zambiri zimadziwika ndi "kutalika kwakukulu, denga lalitali, ndi nthawi yayitali yogwirira ntchito", zomwe zimafuna kwambiri "kufanana, kukhazikika, ndi kuphimba" kwa kuyatsa. FRP (fiberglass reinforced plastic) mapanelo owunikira masana amatha kukwaniritsa izi.

Kuunikira kwadzaoneni, kunyezimira-kwaulere komanso kopanda khungu: FRP (fiberglass reinforced plastic) kuwala-mapanelo otumiza amakhala ndi kuwala kwa 75% -85%, ndipo kuwalako kumawonekera atamwazitsidwa ndi fiberglass, kupewa kunyezimira komwe kumachitika ndi galasi. Ngakhale m'nyumba zamafakitale zokhala ndi kutalika kopitilira 10 metres, kuwala kumatha kuphimba mizere yopangira, malo osungira, ndi madera ena, kuchepetsa zolakwika zomwe zimachitika chifukwa cha kusayatsa kokwanira kwanuko.

Zogwirizana ndi-zikuluzikulu zokhala ndi mawonekedwe osavutikira: Ma skylights a FRP amatha kusinthidwa malinga ndi utali wake ndipo amatha kusanjidwa ngati mafunde kuti agwirizane ndi ma 30 metres kapena kupitilira apo. Mosiyana ndi magalasi, safunikira kugawidwa m'zidutswa ting'onoting'ono kuti akhazikike, kuchepetsa kusokoneza kwa kuwala komwe kumachitika chifukwa cha splicing seams, kuwapanga kukhala oyenera kwambiri-zinyumba zazikulu monga mafakitale azitsulo ndi malo osungiramo katundu.

-kutumiza kwa kuwala kosasunthika kwanthawi yayitali komanso kuchepetsedwa pang'ono pazaka khumi: Kuwala kwa nyali zapulasitiki wamba kudzachepa ndi 30% mu 3-zaka 5, pomwe zowunikira za FRP, pogwiritsa ntchito zokutira za anti-UV, zimatha kuwongolera kutsika kwa kutsika kwa kuwala kufika Kuchepera 2% pachaka kapena kofanana ndi 2% pachaka. Akagwiritsidwa ntchito bwino kwa zaka 15, amatha kukhalabe ndi kuwala kopitilira 60%, kupeŵa kufunika kosinthira mapanelo pafupipafupi m'nyumba zamafakitale chifukwa chowunikira kosakwanira.

2. Kulimbana ndi mayeso a "hardcore" a chilengedwe cha mafakitale

Nyumba zamafakitale nthawi zambiri zimayang'anizana ndi malo ovuta monga mpweya wowononga, kuwononga zinthu zolemera, komanso nyengo yoipa. Zowoneka bwino za FRP (fiberglass reinforced plastic) zowunikira zimatha kuthana ndi zovuta izi, kuchepetsa zoopsa zachitetezo komanso ndalama zosamalira.

Zosawonongeka-zosamva asidi ndi alkali-zosamva, zoyenererana ndi maphunziro apadera: Chemical, electroplating, pickling ndi malo ena ogwirira ntchito amatha kutulutsa mpweya wa asidi ndi alkali. Galasi wamba imakhala ndi dzimbiri komanso nkhungu mosavuta, pomwe mapanelo owoneka bwino a FRP amatha kupangidwa ndi utomoni wa vinyl ester, womwe umapangitsa kuti asidi ndi alkali asamve zambiri nthawi 3-5. Pogwiritsa ntchito nthawi yayitali, pamwamba sidzaphulika kapena kusungunuka, ndipo palibe chifukwa chochotsa dzimbiri nthawi zonse kapena kusinthidwa.

Kukana kwakukulu, osawopa kuwonongeka mwangozi: Zomera zamafakitale nthawi zambiri zimakhala ndi ntchito monga kunyamula forklift ndi kukweza makina. Kukaniza kwa ma skylights a FRP ndi nthawi 2-3 kuposa galasi. Ngakhale kugundidwa ndi zinthu zolemera kapena kukumana ndi matalala, kumangowonongeka kwanuko osati kusweka, kupewa kuwonongeka kwa zida kapena kuvulala komwe kumachitika chifukwa cha magalasi osweka.

Kusalimbana ndi nyengo kumagwirizana ndi nyengo yapadera: Kaya kukuzizira kwambiri -madigiri 30 kapena kukawomba ndi mphepo yamkuntho, zounikira zakuthambo za FRP zimatha kugwira ntchito bwino. Kutentha kwake kocheperako kumacheperako kapena kofanana ndi -40 digiri, ndipo kukana kwake kwa mphepo kumatha kufika 2.5kPa, ndikupangitsa kuti ikhale yoyenera ku nyumba zamafakitale m'malo osiyanasiyana anyengo monga madera a m'mphepete mwa nyanja ndi mapiri.

3. Kuchepetsa mtengo wonse wa moyo wa nyumba zamafakitale.

Nyumba zamafakitale zimayika patsogolo "mtengo-wogwira ntchito bwino" komanso "ntchito yabwino." FRP (fiberglass reinforced plastic) zowunikira zimatha kuchepetsa kwambiri ndalama kuyambira pakukhazikitsa koyambirira mpaka kukonzanso pambuyo pake, mogwirizana ndi malingaliro owongolera mtengo wama projekiti amakampani.

Kuyika kopepuka kumapulumutsa ndalama zamapangidwe ndi antchito: Ma skylights a FRP amalemera theka la galasi, kuthetsa kufunikira kwa mafelemu achitsulo olemera ndi ma cranes ngati kuyika magalasi. Gulu limodzi limatha kusunthidwa ndi anthu a 2-3, ndipo nthawi yoyika ma 10,000 masikweya mita ya skylight imatha kufupikitsidwa mpaka masiku 3-5, ndikuwonjezera magwiridwe antchito ndi 50% poyerekeza ndi galasi, kuchepetsa mwachindunji ndalama zogwirira ntchito ndi zida zobwereketsa.

Kukonza pang'ono komanso kusafunikira m'malo, kuchepetsa kutayika kwa nthawi yocheperako: FRP (pulasitiki yolimba ya fiberglass) yowunikira imatha kugwiritsidwa ntchito nthawi zonse kwa zaka 15-25 popanda kusinthidwa, kumangofunika kuyeretsa kosavuta kwapachaka kwa fumbi lapamtunda. Poyerekeza ndi mapanelo apulasitiki wamba omwe amafunikira kusinthidwa zaka 3-5 zilizonse, izi zimapewa kutayika kwanthawi yayitali m'mizere yopanga mafakitale chifukwa chosintha zinthu zakuthambo, zomwe ndizofunikira kwambiri kwamakampani omwe amapanga mosalekeza monga kupanga mankhwala ndi magalimoto.

Kuchepetsa mphamvu ndi kuchepetsa kugwiritsa ntchito mphamvu, -kupulumutsa nthawi yayitali pakugwiritsa ntchito: Thermal insulation coefficient of FRP skylights (0.18W/(m・K)) ndi yotsika kwambiri kuposa ya galasi (0.76W/(m・K)), yomwe ingachepetse kutentha mufakitale m'chilimwe ndi kuchepetsa katundu woziziritsa mpweya ndi 15%; pa nthawi yomweyo, mkulu kuwala transmittance akhoza m'malo 40% -60% ya kuunikira yokumba. Kutengera fakitale ya 10,000㎡, imatha kupulumutsa pafupifupi 80,000-120,000 yuan pamitengo yamagetsi pachaka.
