xov xwm

Fiberglass reinforcement, tseem hu ua GFRP reinforcement, yog ib hom tshiab ntawm cov khoom sib xyaw.Ntau tus neeg tsis paub meej tias qhov sib txawv ntawm nws thiab cov khoom siv hlau zoo li cas, thiab vim li cas peb thiaj li yuav tsum siv fiberglass reinforcement?Cov kab lus hauv qab no yuav qhia txog qhov zoo thiab qhov tsis zoo ntawm fiberglass reinforcement thiab cov hlau zoo tib yam, thiab tom qab kev sib piv, saib seb fiberglass reinforcement puas tuaj yeem hloov cov hlau zoo tib yam?

Dab tsi yogfiber ntauiavcov khoom siv dag zog
Raws li cov khoom siv ua haujlwm siab tshiab, fiberglass reinforcement yog dav siv nyob rau hauv subway tunnels (shield), txoj kev loj, txuas hniav, tshav dav hlau, docks, chaw nres tsheb, dej txuag tej yaam num, underground tej yaam num thiab lwm yam teb, thiab yuav hloov mus rau corrosive ib puag ncig xws li dej phwj tuaj. kev kho cov nroj tsuag, tshuaj nroj tsuag, electrolytic tanks, manhole npog, dej hiav txwv tiv thaiv tej yaam num.Fiberglass reinforcement tuaj yeem daws tau ntau yam teeb meem hauv engineering, tsim kom muaj qhov tsis zoo ntawm cov hlau ib txwm muaj, thiab coj txoj hauv kev txhim kho tshiab rau pej xeem thiab kev tsim kho engineering.

Qhov zoo thiab qhov tsis zoo ntawm cov hlau zoo tib yam thiabfiber ntauiavkev txhawb zog
1, siab load-bearing muaj peev xwm, siab tensile lub zog, lub zog ntawm lub bar yog ob zaug ntau npaum li tib txoj kab uas hla rebar, tab sis qhov hnyav tsuas yog 1/4 ntawm steel bar;
2, ruaj khov elastic hom, txog 1/3 ~ 2/5 ntawm steel bar;
3, Hluav taws xob thiab thermal rwb thaiv tsev, thermal expansion coefficient yog ze rau cov cement dua li cov hlau;
4, zoo corrosion kuj, haum rau siv nyob rau hauv ntub dej los yog lwm yam corrosive ib puag ncig xws li kev txuag dej, txuas hniav, docks thiab tunnels;
5, shear zog yog tsawg, qhov zoo tib yam fiberglass reinforcement shear lub zog tsuas yog 50 ~ 60MPa muaj cov khoom zoo heev.

Nyob rau hauv kev ua tau zoo thiab steel yeej zoo sib xws, thiab pob zeb muaj adhesion zoo, tab sis kuj muaj lub zog tensile siab thiab tsis tshua muaj zog shear, tuaj yeem txiav tau yooj yim ncaj qha los ntawm lub tshuab thaiv kev sib xyaw, tsis ua rau cov cuab yeej txawv txav.

Qhov sib txawv ntawm fiberglass reinforcement thiab steel reinforcement
1, nyob rau hauv cov nqe lus ntawm kev tsim kho lub sij hawm, piv rau zoo tib yam steel tuav, fiberglass reinforcement yog customized los ntawm cov chaw tsim tshuaj paus, vim hais tias lub site tsis tuaj yeem ua tiav, yog li qhov loj me yuav tsum raug tswj kom raug, ib zaug cov khoom tsis raug yuav ua rau ncua sij hawm tsim kho. .Nws cov duab yog customized ncaj qha, uas txo cov kev ua cov kauj ruam ntawm ib tug zoo tib yam steel tuav, thiab lub puab tsaig txoj kev tying hloov cov txheej txheem vuam, txuag lub sij hawm ntau lawm ntawm lub bar tawb.
2, Nyob rau hauv cov nqe lus ntawm kev tsim kho nyuaj, khoov thiab shear tsis kam ntawm fiberglass qhov cuab lub zog yog ntau txawv ntawm cov zoo tib yam steel tuav thiab qhov zoo yog sib dua, yog li nws tsis ruaj khov dua li qub steel tawb nyob rau hauv tus txheej txheem ntawm lub tawb nqa, tawb qis thiab pouring, yooj yim kom pom xoob tawb, tawb jamming, floating thiab lwm yam tshwj xeeb tej yam kev mob, yuav tsum tau tshwj xeeb mloog nyob rau hauv lub tawb tsim thiab lifting.
3, Nyob rau hauv cov nqe lus ntawm kev tsim kho kev ruaj ntseg, piv nrog rau kev tsim kho txoj kev ntawm ib feem los yog kiag li rhuav lub nruam phab ntsa ntawm cov ntaub thaiv npog qhov kawg, lub nruam phab ntsa ntawm fiberglass tawb tuaj yeem nkag ncaj qha los ntawm cov ntaub thaiv npog tshuab, uas zam cov xwm txheej txaus ntshai ntawm av nkos, dej thiab xuab zeb gushing, txuag tus nqi ntawm kev rhuav tshem cov phab ntsa txuas ntxiv, thiab tseem txo cov pa phem ntawm plua plav thiab suab nrov.
4, nyob rau hauv cov nqe lus ntawm kev lag luam, piv nrog cov hlau zoo tib yam, iav fiber reinforcement yog sib dua, uas txo tus nqi ntawm lub tawb, thiab nyob rau tib lub sij hawm, vim lub loj iav fiber tawb, nws txo qhov dav ntawm lub diaphragm phab ntsa, txuag. tus naj npawb ntawm diaphragm phab ntsa interface I-beam los yog xauv cov yeeb nkab, thiab txuag cov nqi.

Nta ntawmfiber ntauiav reinforcement
1, lub zog tensile siab: lub zog tensile ntawm fiberglass qhov cuab lub zog yog zoo dua li cov hlau zoo tib yam, siab dua 20% ntawm tib cov ntsiab lus steel, thiab kev qaug zog zoo.
2, lub teeb yuag: qhov loj ntawm fiberglass reinforcement tsuas yog 1/4 ntawm tib lub ntim ntawm cov hlau, thiab qhov ceev yog nyob nruab nrab ntawm 1.5 thiab 1.9 (g / cm3).
3, muaj zog corrosion kuj: tsis kam rau cov kua qaub thiab alkali thiab lwm yam tshuaj muaj peev xwm tiv taus qhov yaig ntawm cov tshuaj chloride ions thiab cov tshuaj pH tsawg, tshwj xeeb tshaj yog cov corrosion ntawm carbon compounds thiab chlorine compounds muaj zog.
4 、 Cov khoom siv muaj zog sib txuas: cov coefficient ntawm thermal expansion ntawm fiberglass reinforcement yog nyob ze rau cov cement dua li cov hlau, vim fiberglass reinforcement muaj zog dua cov pob zeb sib txuas.
5, muaj zog tsim qauv: lub elastic modulus ntawm fiberglass reinforcement yog ruaj khov, qhov loj yog ruaj khov nyob rau hauv thermal stress, dabtsi yog khoov thiab lwm yam duab yuav arbitrarily thermoformed, zoo kev nyab xeeb kev kawm, tsis-thermal conductivity, tsis-conductive, nplaim retardant anti-static, los ntawm cov qauv kev hloov pauv thiab kev sib tsoo hlau yuav tsis tsim cov txim taws.
6, muaj zog permeability rau magnetic nthwv dej: fiberglass reinforcement yog ib yam khoom uas tsis yog-magnetic, nyob rau hauv lub non-magnetic los yog electromagnetic pob zeb cov tswv cuab tsis tas yuav ua demagnetization kho.
7, kev tsim kho yooj yim: fiberglass reinforcement tuaj yeem tsim tau raws li cov neeg siv khoom xav tau rau ntau qhov sib txawv ntawm ntu thiab qhov ntev ntawm cov qauv thiab cov khoom tsis yog cov qauv, ntawm qhov chaw sib khi muaj cov ntaub nplaum uas tsis yog xim hlau, kev ua haujlwm yooj yim.

Cov saum toj no yog cov kev taw qhia txog qhov zoo thiab qhov tsis zoo ntawm fiberglass reinforcement thiab zoo tib yam steel, fiberglass reinforcement raws li ib tug tshiab high-performance ntaub ntawv, lug siv nyob rau hauv subway tunnels (shield), txoj kev loj, choj, tshav dav hlau, docks, chaw nres tsheb, dej txuag tej yaam num. , underground engineering thiab lwm yam kev lag luam, tuaj yeem hloov kho rau cov dej phwj tuaj kho, cov nroj tsuag tshuaj, electrolytic tanks, manhole npog, dej hiav txwv tiv thaiv tej yaam num thiab lwm yam corrosive ib puag ncig.
