Txoj kev loj hlob ntawm fiber ntau hauv lub tshav pob ntawm lub tsev muaj zog thiab kev tiv thaiv kev phem thiab txo
Fiber ntau lub tsev qhov cuab lub zog yog tsim los ntawm Goldfein nyob rau hauv 1965, thiab polypropylene fiber tau siv nyob rau hauv kev sib tsoo hluav taws kub ntawm cov tub rog hauv Teb Chaws Asmeskas cov tub rog ntawm engineers. Nyob rau xyoo 1960, Tebchaws Asmeskas thiab Europe pib siv cov pob zeb fiber ntau polypropylene rau cov khoom siv cement thiab kev tsim kho. Nyob rau hauv 1971, lub UK tau tsim cov qauv kev cai lij choj rau kev siv cov fibre-reinforced qhob hauv kav thiab fittings. Txij xyoo 1980s, muaj zog thiab muaj peev xwm ua tau zoo tshaj plaws modulus fibers tau tsim nyob rau hauv Tebchaws Meskas thiab Europe kom ntxiv dag zog. Tus nqi ntawm lub tshuab fais fab siv fiber ntau twb tau tshaj li 10% ntawm tag nrho cov nqi ntawm cov pob zeb.
2. Cov neeg tau zoo
Nyob hauv tebchaws Asmesliskas, Tebchaws United Kingdom, Nyiv thiab Western Europe, siv ntau lub pob zeb siv fiber ntau coj los siv rau txoj kev zoo thiab txoj kev davhlau ya davhlau, cov chaw ua haujlwm thiab kev kho tsheb, kev sib txeeb thiab cov chaw tiv thaiv hluav taws. Lub koom haum Japanese lub koom txoos tiv thaiv kev puas tsuaj thiab kev tshawb nrhiav tau ntse tau tsim cov polypropylene fiber reinforced concrete (pp) uas tuaj yeem muaj av qeeg ntau tshaj 1.5 zaus qhov av qeeg ntawm hanshin.
Qhov tshwj xeeb polypropylene fiber ntau reinforced qhob tau siv rau cov nqaj hlau loj loj hauv cheeb tsam hauv chongqing ntiaj teb chaw, uas ntse daws qhov teeb meem ntawm kev sib tw tsis sib haum thiab kev ua kom muaj zog nyob rau hauv kev tsim kho ntawm cov qib siab tej pob zeb ntau.
Tiv thaiv kom tsis txhob muaj kev sib tsoo thiab ua kom tsis txhob ntsev cov tshuaj polypropylene polyethylene ciav hlau yog siv rau cov dej tsis ruaj ntawm lub hauv paus thiab qab daus ntawm lub teb chaws grand theatre. Tsis muaj txhaws teeb meem tshwm sim nyob rau hauv txoj kev txheej txheem tag nrho. Tus choj Hunan yuehu yog ib lub pob zeb polypropylene fiber ntau reinforced qhob ceev nruj choj, uas ua tau raws li cov txheej txheem dynamic thiab static test thiab ua raws li cov qauv tsim.
