FRP, Imadziwikanso kuti fiber-reinforced polymer, ndi chinthu chophatikizika chopangidwa ndi ulusi wolimbitsa ndi utomoni wa matrix. Cholinga chake chachikulu ndikuthana ndi vuto la dzimbiri lachitsulo lomwe limafooketsa zida zachikhalidwe zolimba za konkriti.
FRP ili ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana chifukwa cha kuthekera kwake kusinthidwa ndi mitundu yosiyanasiyana ya utomoni woyambira monga poliyesitala wosaturated, epoxy, vinyl ester, ndi polyurethane. Ma resinswa ali ndi zinthu zapadera zomwe zimathandiza FRP kukwaniritsa zofunikira zosiyanasiyana.
Kuphatikiza apo, FRP imagwiritsanso ntchito mitundu yosiyanasiyana ya ulusi wolimbikitsira, kuphatikiza ulusi wagalasi, ulusi wa basalt ndi mpweya wa kaboni, womwe uli ndi zinthu zapadera monga mphamvu yayikulu, kukana kwa dzimbiri komanso kulimba. Zotsatira zake, FRP imakhala yosunthika komanso yothandiza pomanga ndi zomangamanga.
galasi fiber

Chithunzi cha FRPamaonedwa kuti ndi njira yotheka kusiyana ndi zitsulo zachikhalidwe pomanga ntchito zomanga ndipo akudziwika kwambiri chifukwa cha ubwino wake wapadera.
Chimodzi mwa zifukwa zazikulu zowonongeka zowonongeka ndi kuwonongeka kwa zitsulo zolimbitsa zitsulo mu konkire. Sikuti izi zimafupikitsa moyo wa konkire, zingayambitsenso kuwonjezereka kwa ndalama zowonongeka ndi zoopsa za chitetezo. Komabe, pogwiritsa ntchito fiberglass rebar, vuto la dzimbiri limatha kuthetsedwa.
Mwachitsanzo,GRECHO fiberglass rebar amapangidwa kwathunthu ndi zinthu zopanda zitsulo, kupereka njira yokhazikika yomwe imapikisana ndi zitsulo zotsika mtengo. Kuphatikiza apo, inertness yake yamagetsi imapangitsa kuti ikhale yoyenera kutumizidwa kumadera ovuta.
Zotsatirazi ndi mawonekedwe ndi kugwiritsa ntchito kwa FRP rebars:
Kulimbana ndi Corrosion:
Chimodzi mwazabwino zazikulu za FRP rebar ndikukana kwa dzimbiri. Mosiyana ndi chitsulo, chomwe chimapangitsa dzimbiri ndi dzimbiri pamene chimalowa mu chinyezi, FRP rebar sichiwononga. Izi zimapangitsa kukhala koyenera kwa zomanga m'madera am'madzi, m'mphepete mwa nyanja ndi malo okhala ndi chinyezi chambiri.
Mphamvu Zapamwamba, Zopepuka:
FRP rebar ili ndi chiyerekezo champhamvu mpaka kulemera, kutanthauza kuti imalemera pang'ono kuposa chitsulo pomwe imakhala ndi mphamvu zofananira kapena zokulirapo. Izi zimapangitsa kutumiza, kusamalira ndi kukhazikitsa mosavuta. Ngakhale kulemera kwake, FRP rebar ili ndi mphamvu zolimba kwambiri.
Zosayendetsa:
FRP rebar si conductive, kutanthauza kuti siyendetsa magetsi. Katunduyu amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mabwalo monga milatho ndi kuyika kwamagetsi, komwe kukhalapo kwa zinthu zochititsa chidwi kungayambitse ngozi.
Kukhalitsa:
FRP rebar imakhala ndi moyo wautali chifukwa cha kukana kwawo kuzinthu zosiyanasiyana zachilengedwe. Simakhudzidwa ndi cheza cha UV, kusinthasintha kwa kutentha kapena kuzizira kozizira. Katunduwa amapanga FRP rebar kukhala yoyenera pama projekiti a zomangamanga pomwe kulimba ndikofunikira.
Non-magnetic and non-conductive:
FRP rebar ndi yopanda maginito komanso yosagwiritsa ntchito, ndikupangitsa kuti ikhale yabwino kwa malo ovuta momwe kusokoneza kwamagetsi kumafunika kuchepetsedwa, monga zipatala, malo a MRI ndi malo opangira deta.
Kugwiritsa ntchito mipiringidzo yachitsulo ya FRP ndi:
Civil Infrastructure:
Zithunzi za FRPamagwiritsidwa ntchito pomanga milatho, misewu yayikulu, tunnel ndi malo oimikapo magalimoto kuti alimbikitse konkire ndikuwonetsetsa kukhazikika kwanthawi yayitali pazovuta zachilengedwe.
Kapangidwe ka Marine:
FRP rebars imagwiritsidwa ntchito kwambiri m'mabwalo am'madzi monga madoko, madoko, madoko ndi nyumba zam'mphepete mwamadzi komwe kukhudzana ndi madzi amchere, chinyezi ndi zinthu zowononga ndizokwera.
Zomangamanga:
FRP rebar ikugwiritsidwa ntchito kwambiri m'nyumba zogona komanso zamalonda kulimbitsa zomanga za konkriti monga ma slabs, mizati, makoma ndi maziko.
Kukonza Zomangamanga:
FRP rebar imagwiritsidwa ntchito kukonzanso ndi kulimbikitsa zida zomwe zilipo kale zomwe zikuwonongeka kapena zimafuna kulimbikitsidwa kwina.
Malo Oyeretsera Madzi Otayira:
FRP rebars imagwiritsidwa ntchito kwambiri m'malo opangira madzi oyipa omwe amakumana ndi zinthu za acidic komanso zowononga.
Mapulogalamu Aukadaulo:
FRP rebars itha kugwiritsidwa ntchito pazantchito zamaluso monga kukhazikitsa magetsi, zipatala, malo a MRI ndi malo opangira ma data chifukwa cha zinthu zomwe sizimayendera maginito komanso zopanda ma conductive.
Ponseponse, FRP rebar imapereka zabwino zambiri, kuphatikiza kukana dzimbiri, kulimba kwambiri, kulimba, komanso zinthu zosagwiritsa ntchito, zomwe zimapangitsa kuti ikhale yankho losunthika komanso lothandiza pazosowa zosiyanasiyana zomanga.
CHIFUKWA CHIYANI KUSANKHA FRP REBAR
Lingaliro losankha FRP rebar limafuna kulingalira mosamala zinthu monga mtundu, magwiridwe antchito ndi mtengo. Kusiyanitsa pakati pa zosinthazi ndikofunikira popanga chosankha mwanzeru. Tsoka ilo, anthu nthawi zambiri amaika patsogolo mapindu anthawi yomweyo ndikuwononga mapindu a nthawi yayitali omwe angapezeke. Ngati titenga njira zazifupi lero ndikunyalanyaza kukonzekera koyenera, mosakayikira tidzawononga ndalama zambiri pakugwetsa mobwerezabwereza ndikumanganso mtsogolo. Ngakhale mtengo woyamba wa FRP rebar umakhala wokwera,mapindu a nthawi yayitali kulimba kwake komanso kuchepetsedwa kwa chisamaliro kumaposa ndalama zoyambira. Kukonzekera mwanzeru ndikofunikira tsopano, kuphatikiza kuwunika mosamalitsa zolosera za moyo wautumiki, zomwe ndizofunikira kuti uinjiniya wamtengo wapatali wokhalitsa. Kumanga maziko olimba a dziko lathu ndikumanga nyumba zolimba kumafuna kugwiritsa ntchito zida zapamwamba komanso zogwira mtima.
Poganizira mawonekedwe anu a carbon, ndizofunika kudziwa kuti kupanga chitsulo kumakhala ndi mphamvu zambiri zachilengedwe kuposa kupanga fiberglass rebar. Izi zimakhala zoona ngakhale osaganiziranso zowonjezera za carbon zomwe zimapangidwa ndi kugwetsa mobwerezabwereza ndi kubwezeretsa.
Potenga njira yoyang'ana kutsogolo ndikuganizira zopindulitsa zomwe zingabwere m'tsogolomu, tikhoza kutsimikizira kuti zochita zathu zimabweretsa zotsatira zokhazikika komanso zokhalitsa.
