Ua ntej dhia mus rau hauv daim ntawv thov, cia peb luv luv txhais cov khoom. Cold drawn steel fibers yog tsim los ntawm kev kos cov hlau xaim los ntawm kev tuag ntawm chav tsev kub. Cov txheej txheem no nce tensile zog, refines lub grain qauv, thiab tsim ib tug du, siab - zog- lub zog filament. Cov fibers no feem ntau yog ntxiv rau cov pob zeb sib xyaw hauv cov tshuaj tshwj xeeb ( ntsuas hauv kg / m³), qhov chaw uas lawv tawg randomly thoob plaws hauv matrix, tsim kom muaj peb -sib nqus qhov cuab lub zog- qhov ntev ntawm qhov txuas uas tuav cov pob zeb ua ke txawm tias tom qab tawg.
Kev nkag mus zoo tshaj -Level Application Scenarios
Rau thawj- cov neeg siv sijhawm, cov haujlwm zoo tshaj plaws yog cov uas qhov zoo ntawm steel fiber ntau -cov pob zeb siv zog (SFRC) tau pom meej meej thiab qhov chaw logistics ncaj nraim.
1. Muaj Flooring thiab Warehouse Warehouse Slabs
Qhov no yog arguably qhov feem ntau thiab kev vam meej nkag point rau txias drawn steel fiber.
Teeb meem:Cov pob zeb ua vaj huam sib luag hauv cov chaw muaj kev lag luam yog qhov ua rau tawg tawg thiab tuaj yeem ua tsis tau raws li cov ntsiab lus hnyav los ntawm cov tshuab racking lossis rov ua dua los ntawm kev tsheb forklift.
Kev daws:Qhov sib faib tsis sib haum ntawm cov hlau fibers muab cov ncej zoo tshaj plaws - tawg ductility. Nws txo cov kab nrib pleb dav thiab tswj shrinkage cracking los ntawm qhov pib. Qhov no ua rau hauv pem teb tougher, ruaj khov dua uas tuaj yeem tiv taus qhov cuam tshuam thiab hnyav hnyav hnyav yam tsis muaj qhov hnyav.
Cov txiaj ntsig rau Beginners:Kev txhim kho kev ua tau zoo yog ntsuas tau yooj yim. Cov neeg cog lus thiab cov tswv tuaj yeem pom qhov txo qis ntawm kev tawg thiab muaj kev siv sijhawm ntev dua - kev tu lub sijhawm. Nws kuj tseem ua kom yooj yim kev tsim kho los ntawm kev tshem tawm lub sijhawm thiab kev ua haujlwm uas yuav tsum tau ua rau qhov chaw thiab ruaj ntseg hlau mesh.
2. Pavements thiab Sidewalks
Rau cov phiaj xwm hauv nroog thiab kev lag luam uas cuam tshuam nrog kev ua haujlwm hauv tsev, SFRC muab cov kev daws teeb meem ntev dua -.
Teeb meem:Cov pavements thiab txoj kev ib txwm muaj tuaj yeem tsim cov kab nrib pleb los ntawm subbase thiab muaj kev puas tsuaj los ntawm khov -thaw cycles thiab de- icing ntsev.
ntsev.
Kev daws:Cov fibers ua raws li micro- txhawb nqa, txuas hla micro- tawg thiab tiv thaiv lawv los ntawm kev nthuav tawm mus rau qhov loj dua, cov qauv ua txhaum. Qhov no txhim kho qhov qaug zog tiv thaiv ntawm pavement.
Cov txiaj ntsig rau Beginners:Daim ntawv thov no tso cai rau kev txo qis hauv slab thickness thaum tswj kev ua haujlwm, muab cov khoom txuag. Kev txhim kho durability ua rau txo qis cov nqi ntawm lub neej, qhov muag muaj zog rau cov tswv haujlwm.
3. Precast Concrete Elements
Kev lag luam precast yog qhov zoo tshaj plaws rau SFRC vim nws qhov chaw tsim khoom tswj tau.
Teeb meem:Precast cov ntsiab lus xws li manhole npog, trench drains, me me tuav phab ntsa thaiv, thiab paving chij yog tsis yooj yim thaum tuav thiab thauj. Lawv tuaj yeem nkig thiab tawg thaum muaj kev cuam tshuam.
Kev daws:Ntxiv cov khaub thuas kos steel fibers ua tau zoo txhim kho lub caij toughness thiab cuam tshuam tsis kam. Nws pab cov khoom muaj sia nyob ntawm demolding, tuav, thiab shipping txheej txheem nrog deb tsawg breakage.
Cov txiaj ntsig rau Beginners:Rau precasters, qhov no txhais ncaj qha rau txo cov khib nyiab thiab cov khoom zoo dua. Cov fibers feem ntau tuaj yeem hloov cov hlua txuas ntxiv, ua kom yooj yim rau cov txheej txheem tsim khoom thiab ua kom lub voj voog casting.
4. Kev tiv thaiv kev nqes hav thiab kev tiv thaiv kev yaig (Shotcrete)
Siv cov hlau fiber ntau hauv shotcrete yog ib qho me ntsis ntxiv tab sis siv tau zoo heev uas siv tau nrog cov cuab yeej tsim nyog.
Teeb meem:Teeb meem:Cov av slopes, embankments, thiab tunnel linings yuav tsum tau ib txheej ntawm pob zeb los tiv thaiv yaig. Plain shotcrete tuaj yeem nkig thiab yuav tsis ua raws li qhov zoo ntawm lub substrate.
Kev daws:Steel fiber ntau-cov ntaub ntawv ntxiv muaj zog muaj zog ntau dua cohesive thiab yooj. Cov fibers khi cov matrix ua ke, tso cai rau nws nqus ntau zog thiab tiv taus me me hauv av tsis ua haujlwm.
Cov txiaj ntsig zoo rau cov pib tshiab: Thaum xav tau cov cuab yeej tshwj xeeb txau, qhov tshwm sim yog qhov muaj kev nyab xeeb dua, muaj zog dua, thiab ruaj khov dua li hauv ob sab phlu piv rau cov mesh- ntxiv cov tshuaj tua kab mob, vim tias tsis muaj kev pheej hmoo ntawm corrosion tom qab txheej.
Cov txiaj ntsig tseem ceeb rau thawj -Cov neeg siv sijhawm
Simplified Kev Tsim Kho:Tshem tawm qhov xav tau rau qhov chaw thiab qhov chaw rebar lossis mesh, ua kom cov txheej txheem kev tso kawm.
Isotropic Reinforcement:Muab cov khoom sib xws, ntau-kev taw qhia lub zog thoob plaws tag nrho cov ntim ntawm cov pob zeb, tsis zoo li cov phiaj xwm mesh / rebar.
Txhim kho Durability:Txhim khu kev tiv thaiv kev cuam tshuam, kev puas tsuaj, thiab qaug zog, ua rau cov qauv siv ntev dua nrog kev saib xyuas tsawg dua.
Tus nqi -Kev ua tau zoo:Txawm hais tias tus nqi ntawm cov khoom siv rau ib lub cubic meter ntawm cov pob zeb yuav siab dua, kev txuag nyiaj hauv kev ua haujlwm, lub sijhawm, thiab kev ua haujlwm ntev - feem ntau ua rau tus nqi qis dua.

Rau cov kws tsim khoom, cov neeg cog lus, thiab cov neeg tsim khoom tab tom nrhiav kev siv cov khoom siv niaj hnub siv los tsim cov khoom siv, cov khoom siv txias kos steel fiber ntau nthuav tawm qhov tsawg - pheej hmoo, siab - khoom plig. Pib nrog cov ntawv thov ncaj nraim xws liindustrial pem teb, pavements, precast ntsiab, thiab shotcretetso cai rau cov pab pawg los tsim kev ntseeg siab thiab ua tim khawv txog qhov kev hloov pauv ntawm cov khoom siv sib xyaw no. Los ntawm kev sib koom ua ke txias kos steel fiber ntau, koj tsis yog tsuas yog nchuav pob zeb; koj tab tom tsim kom ntse dua, muaj zog dua, thiab muaj zog dua infrastructure.
