Polypropylene fiber (PPF) yog ib hom khoom siv polymer uas muaj qhov hnyav sib dua, muaj zog heev, thiab tiv taus corrosion. Qhov tsis kam ntawm cov pob zeb ua vaj tse tuaj yeem txhim kho los ntawm kev ntxiv cov polypropylene fibers. PPF tuaj yeem ua kom zoo dua qhov pore loj ntawm cov pob zeb ua vaj tse. Yog li ntawd, qhov ruaj khov ntawm cov pob zeb ua vaj tse tau txhim kho ntau vim tias PPF tuaj yeem thaiv kev nkag mus ntawm dej lossis cov ions tsis zoo hauv cov pob zeb ua vaj tse. Cov ntsiab lus fiber sib txawv, txoj kab uas hla fiber, thiab qhov sib xyaw ua ke ntawm cov fiber yuav muaj cov teebmeem sib txawv ntawm cov ntsuas ruaj khov. Qhov ruaj khov ntawm cov pob zeb ua vaj tse tuaj yeem txhim kho ntxiv los ntawm kev sib xyaw ua ke PPFs thiab cov hlau fibers. Qhov tsis zoo ntawm PPF hauv kev siv hauv cov pob zeb ua vaj tse yog qhov tsis zoo hauv cov pob zeb ua vaj tse thiab kev sib txuas tsis muaj zog nrog cov cement matrix. Cov txheej txheem los kov yeej cov kev tsis zoo no yog siv cov fiber hloov kho nrog nanoactive hmoov lossis kev kho tshuaj.

Cov fiber tiv thaiv kev tawg yog cov fiber ntau monofilament organic uas muaj zog heev uas siv cov fiber-grade polypropylene ua cov khoom siv raw thiab ua tiav los ntawm cov txheej txheem tshwj xeeb. Nws muaj cov tshuaj tiv thaiv acid muaj zog, alkali muaj zog, thermal conductivity tsis muaj zog, thiab cov khoom siv tshuaj ruaj khov heev. Kev ntxiv mortar lossis concrete tuaj yeem tswj tau cov kab nrib pleb me me los ntawm kev hloov pauv kub hauv theem pib ntawm cov yas shrinkage ntawm mortar thiab concrete, tiv thaiv thiab tiv thaiv kev tsim thiab kev loj hlob ntawm cov kab nrib pleb, thiab txhim kho qhov kev tiv thaiv kab nrib pleb, kev tsis nkag, kev cuam tshuam thiab kev tiv thaiv av qeeg. Nws tuaj yeem siv dav hauv kev tsim kho dej hauv av, ru tsev, phab ntsa, pem teb, pas dej ua ke, qab nthab, txoj kev thiab choj hauv kev lag luam thiab pej xeem kev tsim kho. Nws yog cov khoom siv tshiab zoo tagnrho rau kev tsim kho mortar thiab concrete nrog kev tiv thaiv kev tawg, tiv thaiv kev nqus thiab kev puas tsuaj.

Kev tsim kho tshuab thiab cov kauj ruam
①Raws li qhov ntim ntawm cov pob zeb sib xyaw txhua lub sijhawm, qhov hnyav ntawm cov fiber ntxiv txhua lub sijhawm raug ntsuas raws li qhov yuav tsum tau ua ntawm qhov sib xyaw sib piv (lossis qhov sib xyaw kom pom zoo).
② Tom qab npaj cov xuab zeb thiab cov pob zeb, ntxiv cov fiber. Nws raug pom zoo kom siv lub tshuab sib tov yuam. Ntxiv cov khoom sib xyaw ua ke nrog cov fiber rau hauv lub tshuab sib tov, tab sis them sai sai kom ntseeg tau tias cov fiber ntxiv rau ntawm cov khoom sib xyaw thiab sib tov kom qhuav li 30 vib nas this. Tom qab ntxiv dej, sib tov kom ntub li 30 vib nas this kom cov fiber tawg tag.
③ Tom qab sib tov tas, coj cov qauv mus kuaj tam sim ntawd. Yog tias cov fibers tau sib xyaw ua ke rau hauv monofilaments, cov pob zeb tuaj yeem siv tau. Yog tias tseem muaj cov fibers sib xyaw ua ke, ncua lub sijhawm sib tov los ntawm 20-30 vib nas this ua ntej siv.
④ Cov txheej txheem tsim kho thiab kev saib xyuas ntawm cov pob zeb uas muaj fiber ntau zoo ib yam li cov pob zeb ib txwm muaj. Npaj siv tau.
Cov fibers micro polypropylene (PP) feem ntau siv ua cov khoom siv txhawb zog hauv cov ntawv thov shotcrete. Shotcrete, tseem hu ua sprayed concrete, yog ib txoj kev siv cov pob zeb siv lub tshuab txau siab. Kev ntxiv cov fibers micro PP rau hauv shotcrete muaj ntau qhov zoo:

Kev Tswj Qhov Tawg:

Cov xov paj me me PP pab tswj kev tawg ntawm cov kab nrib pleb hauv cov ntawv thov shotcrete. Lawv ua haujlwm ua cov khoom txhawb nqa thib ob, muab kev txhawb nqa ntxiv thiab txo qhov muaj peev xwm rau cov kab nrib pleb kom nthuav dav.
Kev Ruaj Kho Dua:

Qhov muaj cov micro PP fibers ua rau cov shotcrete ruaj khov dua los ntawm kev ua kom nws tsis txhob tawg, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ib puag ncig hnyav lossis thaum raug rau cov voj voog khov-thaw.
Kev Tiv Thaiv Kev Cuam Tshuam Zoo Dua:

Cov fibers me me PP pab txhawb rau qhov tiv taus kev cuam tshuam ntawm shotcrete, ua rau nws muaj zog dua thiab muaj peev xwm tiv taus lub zog xws li kev cuam tshuam lossis kev sib txhuam. Qhov no muaj txiaj ntsig zoo rau cov ntawv thov xws li cov ntaub thaiv qhov av lossis phab ntsa.
Txo Kev Ntsws Yas Uas Tawg:

Thaum pib kho, cov shotcrete yuav yooj yim rau kev tawg ntawm cov yas shrinkage. Cov xov micro PP pab txo qhov teeb meem no los ntawm kev txo qhov tshwm sim thiab qhov dav ntawm cov kab nrib pleb no.
Kev Ruaj Ntseg Ntxiv:

Qhov ntxiv cov micro PP fibers ua rau cov shotcrete muaj zog dua, ua rau nws yooj ywm dua thiab tiv taus kev thauj khoom dynamic. Qhov no tseem ceeb heev rau cov ntawv thov uas cov shotcrete yuav raug kev txav mus los ntawm cov qauv lossis cov av qeeg.
Kev Tiv Thaiv Kev Xeb:

Cov xov micro PP tsis xeb, muab kev ruaj khov mus sij hawm ntev thiab tiv taus kev puas tsuaj hauv qhov chaw muaj kev kub ntxhov. Qhov no sib txawv ntawm cov hlau txhawb nqa, uas tuaj yeem xeb dhau sijhawm.
Kev Ua Haujlwm Shotcrete Zoo Dua:

Kev siv cov micro PP fibers tuaj yeem ua rau cov shotcrete ua haujlwm tau zoo dua, ua rau nws yooj yim dua rau kev tuav thiab txau. Qhov no yog qhov tseem ceeb rau kev ua tiav daim ntawv thov sib xws thiab qhov tiav xav tau.
Thaum muab cov micro PP fibers rau hauv cov khoom sib xyaw shotcrete, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov lus qhia tsim cov khoom sib xyaw kom raug. Cov ntsiab lus ntawm cov fiber, qhov ntev, thiab kev faib tawm hauv cov khoom sib xyaw shotcrete yuav tsum tau xav txog kom ua tiav cov yam ntxwv kev ua tau zoo. Yuav tsum tau siv cov kev ntsuas tswj xyuas zoo thiab kev sim kom ntseeg tau tias cov shotcrete ua tau raws li cov lus qhia ntawm qhov project thiab cov qauv kev lag luam cuam tshuam.

Ib yam li cov khoom siv ntxiv rau hauv cov pob zeb ua vaj tse, kev sab laj nrog tus kws tshwj xeeb shotcrete lossis tus kws ua vaj tse yog qhov zoo kom ntseeg tau tias cov khoom siv fiber ntau PP uas xaiv tau sib haum nrog cov kev ua tau zoo thiab kev nyab xeeb ntawm daim ntawv thov shotcrete tshwj xeeb. Tsis tas li ntawd, cov cai hauv zos thiab cov qauv yuav tsum tau coj los xav txog.

Peb lub hom phiaj yog los pab cov neeg siv khoom kom tau txiaj ntsig ntau dua thiab ua tiav lawv lub hom phiaj. Los ntawm kev ua haujlwm hnyav heev, peb tsim kom muaj kev sib raug zoo ua lag luam ntev nrog ntau tus neeg siv khoom thoob plaws ntiaj teb thiab ua tiav kev vam meej. Peb yuav txuas ntxiv ua peb qhov kev rau siab zoo tshaj plaws los pabcuam thiab ua rau koj txaus siab! Zoo siab txais tos koj los koom nrog peb!
