Taw qhia
Txij li thaum cov pob zeb muaj qhov tsis xws luag, kev txhim kho nws lub zog yuav tsum txo qis qhov tsis xws luag, ua kom nws lub zog, thiab txo qhov kev ntxhov siab ntawm qhov kawg ntawm cov kab nrib pleb. Ntxiv luv luv, nplua, thiab sib npaug PP fibers rau cov cement pob zeb ua pov thawj qhov tawg tseem ceeb - tiv taus, txhawb zog, thiab tawv tawv. Lub hom phiaj tseem ceeb ntawm kev sib txuas cov fibers nrog cov cementitious substrates yog kom kov yeej qhov tsis muaj zog tom qab, yog li txuas ntxiv lub neej kev pab cuam ntawm pob zeb thiab nthuav nws cov ntawv thov.
Polypropylene Fiber yog dab tsi?
Polypropylene fiber ntau, tseem hu ua engineering fiber, qhob fiber ntau, tawg -cov fiber ntau tiv taus, tawg- cov ntaub ntawv pov thawj fiber ntau, hluavtaws fiber, los yog yas fiber ntau, yog siab - lub zog bundled fiber ntau ua los ntawm polypropylene siv cov txheej txheem tsim tshwj xeeb. Thaum ntxiv rau cov pob zeb lossis mortar, nws tswj tau zoo micro- cov kab nrib pleb tshwm sim los ntawm cov khoom xws li yas shrinkage, ziab kom qhuav, thiab kub hloov hauv cov pob zeb (mortar), tiv thaiv thiab tiv thaiv kev tsim thiab kev loj hlob ntawm cov kab nrib pleb. Qhov no txhim kho qhov tawg - tiv taus thiab impermeable cov khoom ntawm cov pob zeb, nrog rau nws cov kev cuam tshuam thiab seismic tsis kam, yog li txhim kho nws cov kab nrib pleb, impermeability, abrasion resistance, toughness, thiab txuas nws lub neej kev pab cuam.
Polypropylene Fiber Txhim Kho Cov Khoom Siv Ua Haujlwm Li Cas?
1. Txhim kho lub cev zoo
Txo kev sib cais thiab los ntshav: Cov fibers tsis sib xws faib ua peb- cov qauv sib txuas sib txuas, txhawb kev sib sau ua ke, txwv tsis pub los ntshav thiab sib cais hauv cov pob zeb tshiab, thiab txhim kho kev ua haujlwm.
Regulated Setting Sijhawm: Tsawg fiber ntau admixture nce lub sijhawm pib ntawm pob zeb los ntawm 1-1.5 teev, thiab me ntsis nce lub sijhawm teem sijhawm kawg yam tsis muaj kev cuam tshuam rau kev ua haujlwm.
Txo Shrinkage Cracks: Zoo inhibits yas shrinkage thiab kom qhuav shrinkage tawg, txo cov tsis yog - cov kab nrib pleb los ntawm 50% -90%.
2. Txhim kho cov cuab yeej cuab tam
Nce Compressive thiab Flexural Strength: Txhim kho lub zog tseem ceeb ua ntej 0.1% admixture, txo cov kab nrib pleb los ntawm kev tawg -inhibiting cuam tshuam thiab indirectly txhawb zog kev loj hlob.
Txhim kho qhov cuam tshuam thiab qaug zog tiv thaiv: Fibers tiv thaiv kev tawg tawg, ua kom cov pob zeb muaj peev xwm tiv taus qhov cuam tshuam thiab rov ua dua.
Nce Toughness: Ua rau cov ncej- tawg lub zog ntawm cov pob zeb siab dua li cov pob zeb, txhim kho qhov flexural toughness Performance index.
3. Txhim khu kev ruaj ntseg
Txhim kho Impermeability: Blocks capillary kab nrib pleb, txo qhov muaj peev xwm nkag mus rau cov kab nrib pleb, thiab txhim kho impermeability txog li 70%.
Txhim khu khov kho-thaw tsis kam: txo qhov kub thiab txias, tiv thaiv micro- tawg tawm, thiab tuaj yeem ntau tshaj ob npaug ntawm qhov khov -thaw qib qib.
Kev qeeb carbonation thiab alkali- cov tshuaj tiv thaiv sib sau: Txo kev tawg, thaiv CO₂ thiab noo noo nkag mus, thiab cuam tshuam tsis pub carbonation thiab alkali- cov tshuaj tiv thaiv sib sau.
4. Txhim kho qhov hluav taws kub:
Thaum qhov kub thiab txias, cov fibers yaj los ua cov channel, tso dej vapor los ntawm sab hauv cov pob zeb, tiv thaiv kev tawg, thiab txhim kho lub sijhawm hluav taws kub thiab qib.
Kev siv ntawm Polypropylene Fibers
Siv hauv qab daus pouring, sab hauv thiab sab nrauv phab ntsa plastering, hydraulic engineering, fais fab engineering, tunnels, pas dej da dej, thiab lwm yam. Nyob rau hauv txoj kev loj choj, tshav dav hlau, thiab lwm yam dej num, nws txhim khu kev tiv thaiv, av qeeg, thiab puas. Hauv shotcrete thiab pob zeb, nws txhim kho compressive thiab flexural lub zog thaum txo qis rov qab poob. Nyob rau hauv mortar thiab precast qhob Cheebtsam, nws txhim kho tag nrho cov kab nrib pleb tsis kam ntawm cov khoom thiab muab kev tiv thaiv zoo rau cov npoo thiab cov ces kaum ntawm precast qhov chaw.
Yuav Siv Li Cas Polypropylene Fibers
1. Polypropylene fibers tsis cuam tshuam nrog cov pob zeb sib xyaw, cov khoom sib xyaw, cov khoom siv ntxiv, lossis cov cement, thiab tsis tas yuav tsum muaj cov khoom sib xyaw tshwj xeeb.
2. Polypropylene fibers yooj yim siv; lawv tsis tas yuav muaj kev hloov pauv rau qhov qub pob zeb sib xyaw tsim, qhov sib npaug ntawm qhov sib npaug, lossis txo qis ntawm cov khoom siv tseem ceeb.
Ua tib zoo ntsuas cov fibers raws li cov qauv tsim thiab cov pob zeb sib xyaw ntim. Tom qab npaj cov aggregate, ntxiv cov fibers nrog rau cov aggregate rau lub tov khoom. Txuas lub sijhawm sib tov los ntawm 30-60 vib nas this. Tom qab sib tov, coj ib qho piv txwv. Yog tias cov fibers sib npaug sib npaug, cov pob zeb yog npaj rau kev siv. Yog tias tseem muaj cov pob khoom ntawm cov fibers, txuas lub sijhawm sib xyaw los ntawm 30 vib nas this ua ntej siv.
Cov ntsiab lus
Polypropylene fiber ntau yog ib hom tshiab ntawm pob zeb reinforcing fiber, feem ntau hu ua "thib ob reinforcement" hauv pob zeb. Cov pob zeb sib xyaw ua ke nrog polypropylene fibers tuaj yeem ua kom zoo dua qub thiab txhim kho kev ua haujlwm tag nrho. Nws yog tus cwj pwm los ntawm nws txoj kev koom ua ke yooj yim, tus nqi qis, thiab kev ua haujlwm zoo heev. Raws li ib qho tshiab pob zeb reinforcing fiber ntau, polypropylene mesh fiber ntau tau dhau los ua ib lub ntsiab lus kub tshiab hauv kev tshawb fawb thiab kev siv fiber ntau -cov pob zeb siv zog, tom qab iav fiber ntau, steel fiber ntau, thiab stainless hlau fiber ntau.
