Steel fiber yog npaj los txhim kho cov yam ntxwv zoo ntawm pob zeb tom qab nws tau txais nws lub zog tsim. Nws yog ib qho tseem ceeb tias kev siv cov fiber ntau yog qhov yooj yim heev, thiab cov thev naus laus zis txawv ntawm qhov nws tuaj yeem siv tau txawm tias cov neeg tsis muaj kev paub ntau hauv kev tsim kho.
Cov khoom siv no ua lub luag haujlwm ntawm lub zog, thiab tseem ua kom muaj kev ntseeg siab ntawm cov phaj. Cov hlau fiber ntau tsim ib qho qauv nrog kev daws teeb meem thaum sib xyaw, uas tuaj yeem ua tau manually lossis mechanically. Kuj tseem muaj steel fiber ntau pob zeb, uas yog ib hom kev ua vaj tse, qhov twg steel fibers ua haujlwm ntawm kev txhawb nqa. Lawv raug faib thoob plaws hauv lub ntim, thiab kev siv cov pob zeb zoo li no tso cai rau koj tshem tawm qee qhov ntawm qhov kev txhawb nqa los ntawm cov qauv, thiab qee zaum nws tuaj yeem tshem tawm tag nrho ntawm qhov muaj cov tsoos bar reinforcement.
Kev ua haujlwm ntawm kev siv steel fiber ntau hauv cov qauv ua tiav los ntawm kev txo cov nqi zog rau kev ua haujlwm ntxiv, nrog rau kev txo qis kev noj cov tshuaj khib nyiab thiab cov hlau. Kev ua haujlwm thev naus laus zis tuaj yeem sib xyaw ua ke, thiab vim li ntawd, cov pob zeb lojNws hloov tawm qhov kev txhawb zog, uas ua rau txo qis kev siv zog los ntawm 27% thiab txuag cov khoom siv hauv tsev ib 1 m3 ntawm cov khoom tiav.
Tshaj siv cov khoom siv
Steel fiber tuaj yeem siv tau:
- hauv cov plag tsev;
- dai panels;
- stilt;
- phab ntsa hauv qab daus;
- seamless floors.
Ntawm lwm yam, cov khoom siv no yog siv rau hauv kev npaj ntawm lub hauv paus, prefabricated qauv, txoj kev thiab kev txhawb nqa panels.
Qhov zoo ntawm steel fiber ntau
Yog tias koj hloov lub mesh reinforcing nrog fiber ntau, lub thickness ntawm cov screed yuav txo qis, thaum nws bearing muaj peev xwm yuav nyob twj ywm. Yog li, steel-fiber-reinforced qhob vaj tse muaj kev tiv thaiv siab rau dynamic thiab zoo li qub loads. Cov qauv tsim tau txais cov txiaj ntsig ntawm kev ua haujlwm tawg, hnav tsis kam, kev vibration endurance nce, nrog rau lub zog.
Yog tias peb piv cov hlau fiber ntau nrog cov khoom siv dag zog, nws tuaj yeem raug sau tseg tias lub sijhawm siv rau kev txhim kho ntawm qhov cuab lub zog yog txo. Qhov no yog vim lub fact tias cov hlau fibers tau ntxiv rau hauv lub tov khoom los yog nyob rau hauv lub Hoobkas, thiab lub sij hawm sib tov yuav kav li ntawm 5 mus rau 15 feeb. Kev vibration tsis kam yog vim qhov tseeb tias cov khoom thauj tau muab faib sib npaug thiab tsis ua rau kev puas tsuaj ntawm pob zeb. Tab sis yog hais tias koj nteg reinforcing tuav nyob rau hauv tus txheej txheem ntawm pouring lub hauv paus, ces lawv yuav tsis tiv thaiv cov tsim ntawm me me tawg. Steel fiber reinforced pob zeb muaj zog tiv thaiv corrosion. Yog tias qhov kev txhawb nqa tau raug cuam tshuam rau qhov tsis zoo, ces nws qhov ntim yuav nce ntxiv hauv cov qauv, uas yuav ua rau kev puas tsuaj ntawm cov txheej txheem tiv thaiv.
Lub ntsiab nta
Yog steel fibers ntxiv rau pob zeb thaum lub sij hawm tsim ntau yam qauv, tom qab ntawd tom kawg yuav muaj kev txhim kho zoo ntawm dabtsi yog khoov thiab tensile lub zog, nrog rau lwm yam, qhov kawg compressibility thiab siab cuam tshuam lub zog yuav ua tiav. Nrog kev pab los ntawm cov ntsiab lus no, nws muaj peev xwm txo qis shrinkage, deformation thiab creep. Cov khoom muaj cua sov-, Frost- thiab hluav taws-resistant, thiab kuj muaj peev xwm tiv taus abrasion.
Specifications
Steel fiber ntau rau pob zeb, daim duab uas tau nthuav tawm hauv tsab xov xwm, yog ib daim hlau, qhov ntev ntawm qhov sib txawv ntawm 0.5 txog 1.2 hli. Qhov ntev ntawm cov ntsiab lus txawv ntawm 25 mus rau 60 mm. Yog tias koj saib ze rau ntawm fiber ntau, koj yuav pom tias nws qhov kawg muaj qhov tshwj xeeb teeb tsa, uas ua rau muaj kev ruaj ntseg adhesion rau cov tshuaj.
Cov ntsiab lus yog ua los ntawm cov hlau tsis tshua muaj carbon, uas yog ib qho ntawm peb chav kawm muaj zog. Thawj yog tus cwj pwm los ntawm qhov ntsuas ntawm 1150 MPa, thaum lub thib ob thiab thib peb muaj lub zog ntawm 1335 thiab 1550 MPa, feem. Kev siv cov hlau fiber ntau hauv qee qhov muaj qhov tsis zoo ntawm kev siv cov cuab yeej cuab tam. steel fiber ntau rau pob zeb,noj ib m3 ntawm uas yog kwv yees li 25-50 kg, tsim ib tug peb-dimensional qauv uas muaj peev xwm tiv taus tensile quab yuam thiab tsis suav nrog qhib microcracks. Cov tom kawg tuaj yeem tsim nyob rau hauv kev cuam tshuam ntawm lub zog load thiab ya raws. Thaum kawg, steel fiber reinforced pob zeb siv tau yam tsis tas yuav kho.
txiaj ntsig ntawm fiber ntau
Steel fiber ntau rau pob zeb, hais los saum toj no, tshem tawm qhov qeeb vim los ntawm kev teeb tsa ntawm cov txheej txheem fasteners. Yog li, nws tsis yog qhov tsim nyog los tso cov kab sib chaws rau hauv pem teb yog tias cov pob zeb loj loj tau tsim. Los ntawm kev ntxiv cov hlau no, cov neeg ua haujlwm tsawg dua tuaj yeem koom nrog, thiab cov pob zeb thiab cov qauv tsim los ntawm nws yuav muaj qhov zoo dua qub, uas tau hais hauv qhov tseeb tias lub zog tensile thiab dabtsi yog khoov tau nce los ntawm 2 zaug, thiab qhov kawg tensile strain yog txhim kho los ntawm 20x ua. Cov qauv siv fiber ntau tuaj yeem siv tau txawm tias nyob hauv thaj chaw muaj kev puas tsuaj.
xeev Standards
Hlau fiber ntau rau pob zeb, GOST uas zoo li 3282-74, yog cov khoom thauj tog rau nkoj uas yog ua los ntawm cov hlau zoo. Qhov tseem ceeb tshaj plaws uas txiav txim siab txog kev tsim khoom yog lub zog tensile, uas pib ntawm 900 N / mm 2. Cov khoom no yog siv rau kev tsim khoom ntawm ntau, nrog rau seamlesspem teb, reinforcing bases thiab restoring txoj kev nto. Qhov no fiber ntau thauj tog rau nkoj yog siv rau cov khoom siv, fortifications, choj qauv, runways thiab hydraulic lug.
Ntawm kev muag khoom koj tuaj yeem pom cov hlau fiber ntau ua los ntawm cov xaim hluav taws xob siab, uas yog coated nrog tooj dag sib xyaw thaum lub sijhawm tsim khoom. Tib lub sijhawm, GOST zoo li 9389-75, thiab lub zog tensile ntawm cov khoom pib ntawm 1200 N / mm2.
Dramix Fiber yam ntxwv
Yog tias koj txaus siab rau Dramix steel fiber ntau rau pob zeb, ces koj yuav tsum paub koj tus kheej nrog nws cov yam ntxwv hauv kev nthuav dav ntxiv. Nws yog ua los ntawm cov hlau tsis tshua muaj carbon steel, uas muab kev txhawb nqa ntau. Cov fiber ntau no yog profiled, yog li nws adheres zoo rau lub pob zeb matrix. Cov khoom siv no tuaj yeem siv rau hauv pem teb hauv kev lag luam, kev tsim cov kwj tubing, tsim cov pob zeb txau thiab nyob rau hauv txhua rooj plaub uas yuav tsum tau txhim kho cov yam ntxwv zoo ntawm pob zeb.
