Tuam Tshoj Kev Tshaj Lij Pp Fiber Rau Pob Zeb - Polypropylene Fibers Micro Polypropylene Fiber Reinforced Concrete Fibers PPF Micro Fibers - Kehui

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 Ua cov qauv tam sim ntawd tom qab sib tov. 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.
