Polypropylene Fiber vs Rebar Mesh

Taw qhia

Kev tawg pob zeb yog ib qho teeb meem feem ntau thiab kim tshaj hauv cov vaj tse pob zeb. Thaum nws los txog rau kev txhawb zog, ntau tus engineers thiab precast tivthaiv manufacturers nug tib lo lus nug: Qhov twg zoo dua, polypropylene fibers lossis steel mesh? Ob lub hom phiaj los txhim kho kev ua tau zoo, tab sis lawv daws teeb meem sib txawv heev.

Polypropylene fibers tsom rau kev tswj kev tawg thaum ntxov thiab qhov chaw zoo, thaum steel mesh yog siv los txhim kho lub zog thiab kev thauj mus los. Kev nkag siab qhov sib txawv no yog qhov tseem ceeb, vim tias xaiv cov khoom tsis raug tuaj yeem ua rau cov nqi tsis tsim nyog, rov ua haujlwm, lossis teeb meem kev ua haujlwm.

Polypropylene Fiber hauv pob zeb yog dab tsi?

Polypropylene fibers yog cov khoom siv hluavtaws ntxiv ncaj qha thaum lub sijhawm sib xyaw ua ke.

Tsis zoo li cov khoom siv dag zog ib txwm muaj, lawv tau sib npaug sib npaug thoob plaws hauv lub pob zeb matrix, tsis yog muab tso rau hauv ib txheej. Lawv lub luag haujlwm tseem ceeb yog tswj cov yas shrinkage thiab tawg thaum ntxov, tshwm sim uas feem ntau tshwm sim hauv thawj ob peb teev tom qab nchuav. Cov fibers no ua hauj lwm los ntawm kev tsim lub microscopic network uas tuav cov pob zeb ua ke raws li cov dej evaporates.

Piv nrog rau cov hlau mesh, polypropylene fibers tsis dais cov qauv loads, tab sis lawv zoo heev ntawm kev tiv thaiv nto tawg thiab txhim kho nto zoo. Lawv yog cov hnyav, tsis yog -corrosive, thiab chemically ruaj khov, ua rau lawv haum rau corrosive los yog ntub ib puag ncig.

Rebar Mesh yog dab tsi thiab Yuav Ua Li Cas Txhim Kho Pob Zeb?

Rebar mesh yog welded steel qhov cuab lub zog ua los ntawm cov kab sib npaug sib npaug ntawm cov kab sib txuas, tsim los txhim kho pob zeb lub zog tensile, vim pob zeb nws tus kheej kuj tsis muaj zog hauv kev nro. Thaum embedded nyob rau hauv lub pob zeb, lub mesh ua hauj lwm ua ke nrog lub hardened pob zeb matrix los tiv thaiv dabtsi yog khoov, stretching, thiab cracking tshwm sim los ntawm cov ntaub ntawv loads, kub hloov, thiab structural txav. Piv nrog rau kev tso ib tus neeg rebars, rebar mesh muaj ntau qhov sib txawv thiab kev teeb tsa sai dua, uas yog vim li cas nws tau siv dav hauv slabs, pem teb, thiab precast qhob ntsiab.

Rebar mesh muab ntsuas lub zog tensile uas engineers tuaj yeem xam thiab tso siab rau hauv kev tsim qauv. Tsis zoo li cov fibers uas sib xyaw ncaj qha rau hauv pob zeb, rebar mesh ncaj qha ua rau kev thauj khoom -cov kabmob muaj peev xwm thiab tswj kev tawg thaum muaj kev ntxhov siab. Thaum muab qhov chaw zoo nrog cov pob zeb ua kom txaus, nws tsim ib qho kev txhim kho ruaj khov uas ua kom zoo dua qub thiab ntev - lub sij hawm kev ncaj ncees.

Polypropylene Fiber vs Rebar Mesh

Crack Tswj Kev Ua Haujlwm

Polypropylene fibers ua lub luag haujlwm hauv kev tswj kev tawg ntawm qhov pib ntawm pob zeb. Vim tias cov fibers tau tawg mus thoob plaws hauv cov pob zeb sib xyaw, lawv pab tuav cov pob zeb tshiab rau hauv qhov chaw raws li cov dej noo evaporates, txo cov yas shrinkage cov kab nrib pleb thiab cov kab nrib pleb zoo, tiv thaiv lawv los ntawm kev tsim cov teeb meem pom. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov khoom siv precast, qhov chaw zoo ntawm cov khoom siv precast yog qhov tseem ceeb; Txawm tias me me tawg tuaj yeem ua rau kev kho, khawb, lossis ua kom tiav sijhawm.

Kev txhawb nqa mesh tuaj yeem pab txo qhov dav ntawm qhov tawg tom qab cov pob zeb ua kom tawv, tab sis nws tsis yog ib qho kev daws teeb meem zoo rau thaum ntxov - theem tawg. Lub qhov tob ntawm qhov reinforcing mesh yog tsau, yog li nws nto tseem tuaj yeem tawg yog tias ziab sai dhau los yog kho tsis sib xws.

Nyob rau hauv qhov tseeb, cov fibers ua raws li tag nrho - cheeb tsam tawg tswj network, thaum lub reinforcing mesh ua raws li cov txheej txheem skeleton. Rau ntau cov precast slabs thiab cov khoom, ntxiv polypropylene fibers yog ib txoj kev ncaj thiab zoo uas tuaj yeem txhim kho cov tsos, txo kev ua haujlwm, thiab ua kom cov khoom ua tau zoo.

Yuav Fiber Hloov Rebar Mesh?

Yog vim li cas Polypropylene Fibers tsis tuaj yeem hloov Reinforceing Mesh rau Structural Strength Enhancement

Kev txhawb nqa mesh ua lub luag haujlwm hauv kev ua vaj tse, coj lub zog tensile thiab pab cov tswvcuab tiv thaiv kev khoov, thauj khoom, thiab ntev - kev ntxhov siab. Nws ua zoo li ib lub thav duab sab hauv, muaj kev nyab xeeb xa cov khoom thauj mus rau cov pob zeb. Polypropylene fibers ua haujlwm sib txawv kiag li. Thaum polypropylene fibers dispersed nyob rau hauv lub pob zeb sib tov tuaj yeem tswj microcracks thiab txhim kho toughness, lawv tsis tuaj yeem tsim txoj kev thauj mus los tas li. Rau cov kab, kab, kab, hauv paus, thiab ib qho kev thauj khoom- cov tswv cuab, kev txhawb nqa mesh tseem ceeb heev thiab tsis tuaj yeem hloov los ntawm fibers.

Thaum twg Fibers tuaj yeem hloov Reinforceing Mesh?

Thaum txhawb nqa mesh feem ntau yog siv los tswj cov kab nrib pleb es tsis yog txhim kho lub zog, polypropylene fibers tuaj yeem hloov tau. Qhov no yog ib yam nyob rau hauv nyias slabs, tsis yog -load- bearing precast slabs, cladding txheej, thiab nto- cov khoom tseem ceeb. Nyob rau hauv ntau daim ntawv thov precast tivthaiv, reinforcing steel muab lub zog, thaum fibers txhim kho kev tawg tsis kam thiab nto zoo.

Cov ntawv thov zoo tshaj plaws rau Polypropylene Fiber

Polypropylene fiber ntau yog qhov zoo tshaj plaws rau cov ntawv thov uas tswj kev tawg, qhov zoo ntawm qhov chaw, thiab kev ua haujlwm ntau lawm yog qhov tseem ceeb tshaj li cov qauv thauj khoom -cov kabmob muaj peev xwm.

Precast phab ntsa vaj huam sib luag thiab façade ntsiab: tshwj xeeb tshaj yog haum rau nyias seem uas thaum ntxov - muaj hnub nyoog cracking thiab defects deg ntau dua.

Pem teb thiab slabs: Pab tswj cov yas shrinkage tawg, tshwj xeeb tshaj yog nyob rau hauv loj pours raug cua los yog siab - kub.

Nyias los yog complex precast Cheebtsam: Zoo - haum rau panels, npog, thiab architectural ntsiab qhov chaw rebar mesh yog ib qho nyuaj los yog inefficient.

High- tso zis precast factories: Fibers yog tov ncaj qha mus rau hauv lub pob zeb, tshem tawm cov phau ntawv mesh tso thiab ua kom lub voj voog ntau lawm.

Corrosion- ib puag ncig yooj yim: Tsis zoo li cov hlau, polypropylene fiber ntau tsis xeb, ua rau nws haum rau qhov chaw ntub lossis hnyav.

Cov ntawv thov zoo tshaj plaws rau Rebar Mesh

Kev txhawb nqa mesh yog qhov zoo tshaj plaws rau cov cuab yeej ua vaj tse nrog cov kev xav tau siab heev rau kev thauj mus los thiab lub zog tensile.

Nws yog feem ntau siv nyob rau hauv kab, kab, thiab hauv paus, qhov twg cov pob zeb yuav tsum muaj kev ruaj ntseg tiv taus ntev - lub sij hawm structural loads. Kev txhawb nqa mesh pab tswj kev ntxhov siab khoov thiab txhim kho tag nrho cov qauv kev ntseeg tau. Txawm hais tias kev teeb tsa yuav tsum tau ua haujlwm ntau dua, nws lub zog ntsuas tau thiab ntev - lub sijhawm ruaj khov ua rau nws tseem ceeb hauv cov ntawv thov tseem ceeb.

Koj yuav tsum xaiv qhov kev txhawb zog twg?

Polypropylene Fiber ntau

Yog tias cov khoom siv pob zeb tsis yog -cov qauv lossis cov khoom thauj me me, polypropylene fiber yog ib qho kev daws teeb meem zoo rau kev tswj cov yas shrinkage tawg thiab txhim kho qhov zoo. Nws yog tshwj xeeb tshaj yog haum rau precast phab ntsa panels, nyias seem, slabs, thiab daim ntaub ntawv uas zoo sib xws finishes thiab ceev ntau lawm voj voog yog ib qho tseem ceeb. Los ntawm kev tshem tawm phau ntawv tso, fiber ntau kuj pab txo lub sijhawm ua haujlwm thiab rov ua haujlwm dua.

Rebar Mesh

Rau kev thauj khoom- cov kabmob xws li kab teeb, kab, kab, hauv paus, thiab cov plag tsev hnyav, rebar mesh tseem tseem ceeb. Nws muab lub peev xwm tensile thiab kev thauj mus los uas fibers hloov tsis tau. Hauv ntau qhov haujlwm ua ntej, kev sib txuas ntawm rebar mesh nrog polypropylene fiber muab qhov txiaj ntsig zoo tshaj plaws - kev ntseeg tau ntawm cov hlau, thiab txhim kho kev tawg thiab ua haujlwm ntev ntawm fiber ntau.

Xaus

Polypropylene fibers thiab reinforcing mesh tsis contradictory, tab sis yog ib tug sib npaug.

Polypropylene fibers ua tau zoo hauv kev tswj kev tawg thaum ntxov, txhim kho qhov chaw zoo, thiab ua kom cov khoom ua tau zoo. Ntawm qhov tod tes, kev txhawb nqa mesh tseem yog qhov tseem ceeb rau kev tsim lub zog thiab kev thauj khoom -cov kabmob muaj peev xwm.

Yog tias koj xav tau kev tswj kom tawg tau zoo dua, txo qis rov ua dua, thiab ua kom zoo dua qub, ces polypropylene fibers tsim nyog tau txais kev txiav txim siab loj thiab yuav tsum tau muab tso rau hauv koj qhov kev txhawb nqa rebar.
