Fiberglass reinforcement, yomwe imatchedwanso GFRP reinforcement, ndi mtundu watsopano wazinthu zophatikizika.Anthu ambiri sadziwa kuti pali kusiyana kotani pakati pa izo ndi zitsulo wamba kulimbitsa, ndipo n'chifukwa chiyani tiyenera kugwiritsa ntchito fiberglass reinforcement?Nkhani yotsatirayi ifotokoza za ubwino ndi kuipa kwa chitsulo cha fiberglass ndi zitsulo wamba, ndipo pambuyo poyerekezera, muwone ngati kulimbitsa magalasi a fiberglass kungalowe m'malo mwa chitsulo wamba?

Ndi chiyanifibergalasikulimbikitsa zinthu
Monga latsopano mkulu-ntchito zakuthupi structural, fiberglass kulimbitsa chimagwiritsidwa ntchito mu tunnel yapansi panthaka (chishango), misewu, milatho, ndege, madoko, masiteshoni, ntchito zosungira madzi, ntchito mobisa ndi madera ena, ndipo akhoza azolowere kuwononga chilengedwe monga zinyalala. zopangira mankhwala, zopangira mankhwala, akasinja a electrolytic, zovundikira mahole, ntchito zoteteza nyanja.Kulimbitsa magalasi a fiberglass kumatha kuthetsa mavuto ambiri muuinjiniya, kupanga zofooka zachitsulo chachikhalidwe, ndikubweretsa mwayi watsopano wachitukuko ku uinjiniya wa zomangamanga ndi zomangamanga.

Ubwino ndi kuipa kwachitsulo wamba ndifibergalasikulimbikitsa
1, kunyamula katundu wambiri, kulimba kwamphamvu kwambiri, kulimba kwa bar ndi kuwirikiza kawiri kuposa rebar m'mimba mwake, koma kulemera kwake ndi 1/4 yokha yazitsulo;
2, Khola mode zotanuka, za 1/3 ~ 2/5 wa zitsulo bala;
3, Kutchinjiriza magetsi ndi matenthedwe, matenthedwe kukulitsa koyenelera ndi pafupi simenti kuposa zitsulo;
4, kukana bwino kwa dzimbiri, oyenera kugwiritsidwa ntchito m'malo onyowa kapena owononga monga kusungirako madzi, milatho, ma docks ndi tunnel;
5, kumeta ubweya wa mphamvu ndizochepa, mphamvu wamba ya fiberglass yolimbitsa tsitsi ndi 50 ~ 60MPa yokha yomwe ili ndi zida zabwino zodulira.

Mu ntchito ndi zitsulo zofanana kwenikweni, ndipo konkire imakhala ndi zomatira zabwino, komanso imakhala ndi mphamvu zolimba kwambiri komanso mphamvu zochepa zometa ubweya, zimatha kudulidwa mwachindunji ndi makina a chishango chamagulu, popanda kuwononga chida chachilendo.

Kusiyana pakati pa fiberglass reinforcement ndi chitsulo kulimbikitsa
1, potengera nthawi yomanga, poyerekeza ndi mipiringidzo wamba zitsulo, kulimbitsa kwa fiberglass kumasinthidwa ndi wopanga, chifukwa malowa sangathe kukonzedwa, kotero kukula kwake kuyenera kuyang'aniridwa bwino, zinthu zolakwika zikadzabweretsa kuchedwa kwa nthawi yomanga. .mawonekedwe ake mwachindunji makonda, amene amachepetsa masitepe processing wa mipiringidzo wamba zitsulo, ndi pachifuwa njira zingwe m'malo ndondomeko kuwotcherera, kupulumutsa nthawi yopanga khola bala.
2, Pankhani ya zovuta zomangamanga, kupindika ndi kukameta ubweya wa fiberglass kulimbitsa ndi kosiyana kwambiri ndi mipiringidzo wamba zitsulo ndi khalidwe ndi opepuka, choncho ndi wosakhazikika kuposa wamba zitsulo khola m`kati kukweza khola, khola kutsitsa ndi kuthira, zosavuta kuoneka lotayirira khola, khola kupanikizana, zoyandama ndi zinthu zina zapadera, amafunikira chisamaliro chapadera mu khola kupanga ndi kukweza.
3, Kumbali ya chitetezo cha zomangamanga, poyerekeza ndi njira yomanga ya pang'onopang'ono kapena kwathunthu kuswa khoma mosalekeza kulimbikitsa khola kumapeto chishango, mosalekeza khoma la fiberglass khola akhoza mwachindunji analowerera ndi makina chishango, amene amapewa zinthu zoopsa za matope, madzi ndi mchenga kuchucha, zimapulumutsa mtengo wothyola khoma lopitirizabe, komanso zimachepetsanso kuipitsidwa kwa fumbi ndi phokoso.
4, ponena za chuma, poyerekeza ndi chitsulo wamba, galasi CHIKWANGWANI reinforcement ndi opepuka, amene amachepetsa mtengo khola, ndipo nthawi yomweyo, chifukwa chachikulu galasi CHIKWANGWANI khola, amachepetsa m'lifupi khoma diaphragm, amapulumutsa. kuchuluka kwa mawonekedwe a khoma la diaphragm I-mtengo kapena chitoliro chotseka, ndikusunga mtengo.

Makhalidwe afibergalasi kulimbitsa
1, kulimba kwamphamvu kwambiri: kulimba kwamphamvu kwa fiberglass kulimbitsa bwino kuposa chitsulo wamba, kupitilira 20% yachitsulo chofananira, komanso kukana kutopa.
2, kulemera kopepuka: kuchuluka kwa fiberglass kulimbikitsa ndi 1/4 yokha ya voliyumu yofanana yachitsulo, ndipo kachulukidwe kali pakati pa 1.5 ndi 1.9 (g/cm3).
3, amphamvu dzimbiri kukana: kukana asidi ndi zamchere ndi mankhwala ena akhoza kukana kukokoloka kwa ayoni kolorayidi ndi otsika pH njira, makamaka dzimbiri wa carbon mankhwala ndi mankhwala klorini wamphamvu.
4, Kumangirira kwamphamvu kwazinthu: coefficient ya kukulitsa kwa matenthedwe a fiberglass kulimbitsa kuli pafupi ndi simenti kuposa chitsulo, chifukwa kulimbitsa kwa fiberglass ndikwamphamvu kuposa kugwirizira konkriti.
5, mawonekedwe amphamvu: zotanuka modulus wa fiberglass kulimbikitsa ndi khola, kukula ndi khola pansi kupsyinjika matenthedwe, kupinda ndi akalumikidzidwa ena akhoza mopanda matenthedwe thermoformed, chitetezo ntchito bwino, sanali matenthedwe madutsidwe, sanali conductive, malawi retardant odana malo amodzi, kupyolera mu kusintha kwa chilinganizo ndi kugunda kwachitsulo sikudzatulutsa zopsereza.
6, kutha kwamphamvu kwa mafunde a maginito: kulimbitsa magalasi a fiberglass ndi zinthu zopanda maginito, mwa mamembala omwe si a maginito kapena ma electromagnetic konkriti safunikira kuchita chithandizo cha demagnetization.
7, yomanga yabwino: fiberglass reinforcement imatha kupangidwa molingana ndi zomwe wogwiritsa ntchito amafunikira pamitundu yosiyanasiyana yamitundu yosiyanasiyana komanso kutalika kwa magawo okhazikika komanso osakhala wamba, kumangiriza tepi yomwe ilibe zitsulo zosapanga dzimbiri, ntchito yosavuta.

Pamwambapa ndi kukhazikitsidwa kwa ubwino ndi kuipa kwa fiberglass kulimbitsa ndi zitsulo wamba, fiberglass kulimbitsa monga latsopano mkulu-ntchito structural zipangizo, chimagwiritsidwa ntchito mu tunnel yapansi panthaka (chishango), misewu, milatho, ndege, docks, malo, madzi kusungirako ntchito. , uinjiniya wapansi panthaka ndi madera ena, amatha kusintha malo opangira zimbudzi, zomera zamankhwala, akasinja a electrolytic, zovundikira manhole, ntchito zoteteza nyanja ndi malo ena owononga.
