Product Detail

Khoom cim npe

Polypropylene fiber (PPF) yog ib yam khoom siv polymer nrog lub teeb yuag, siab zog, thiab corrosion kuj.Kev ua haujlwm tawg ntawm cov pob zeb tuaj yeem txhim kho los ntawm kev ntxiv polypropylene fibers.PPF tuaj yeem ua kom zoo dua qhov pore loj faib ntawm pob zeb.Raws li qhov tshwm sim, qhov ua tau zoo ntawm cov pob zeb ua kom zoo dua qub vim tias PPF tuaj yeem thaiv kev nkag mus ntawm cov dej lossis cov ions tsis zoo hauv cov pob zeb.Cov ntsiab lus fiber ntau sib txawv, fiber ntau txoj kab uas hla, thiab fiber ntau hybrid piv yuav muaj qhov sib txawv ntawm qhov ntsuas qhov ntev.Cov cuab yeej ruaj khov ntawm pob zeb tuaj yeem txhim kho ntxiv los ntawm kev sib txuas PPFs thiab steel fibers.Lub drawbacks ntawm PPF nyob rau hauv daim ntawv thov nyob rau hauv qhob yog qhov imperfect dispersion nyob rau hauv cov pob zeb thiab tsis muaj zog kev sib raug zoo nrog cov cement matrix.Cov hau kev los daws cov teeb meem no yog siv fiber ntau hloov nrog nanoactive hmoov lossis tshuaj kho mob.

Anti-cracking fiber ntau yog lub zog muaj zog bundled monofilament organic fiber uas siv fiber ntau polypropylene ua cov khoom siv raw thiab ua tiav los ntawm cov txheej txheem tshwj xeeb.Nws muaj qhov muaj zog acid tsis kam, muaj zog alkali tsis kam, tsis muaj zog thermal conductivity, thiab tsis tshua muaj tshuaj lom neeg ruaj khov.Ntxiv mortar lossis pob zeb tuaj yeem tswj tau cov micro-cracks los ntawm qhov kub thiab txias ntawm qhov pib ntawm cov yas shrinkage theem ntawm mortar thiab pob zeb, tiv thaiv thiab tiv thaiv kev tsim thiab kev loj hlob ntawm cov kab nrib pleb, thiab zoo heev txhim kho cov pob zeb tawg, impermeability, cuam tshuam thiab av qeeg. kev tiv thaiv tuaj yeem siv dav hauv underground engineering waterproofing, ru tsev, phab ntsa, pem teb, pas dej ua ke, hauv qab daus, txoj kev thiab txuas hniav hauv kev lag luam thiab kev tsim kho vaj tse.Nws yog ib qho khoom siv tshiab zoo tshaj plaws rau mortar thiab qhob engineering nrog kev tiv thaiv kev tawg, tiv thaiv kev tawm tsam thiab kev puas tsuaj.

Lub cev tsis muaj zog:
Fiber Hom: Bundle Monofilament / ntom: 0.91g / cm3
Sib npaug txoj kab uas hla: 18 ~ 48 μm / ntev: 3, 6, 9, 12, 15, 54mm, nws tuaj yeem txiav arbitrarily raws li cov neeg siv khoom xav tau.
Tensile zog: ≥500MPa / modulus ntawm elasticity: ≥3850MPa
Elongation ntawm so: 10 ~ 28% / Acid thiab alkali tsis kam: siab heev
Melting point: 160 ~ 180 ℃ / Ignition point: 580 ℃

Lub luag haujlwm tseem ceeb:
Raws li cov khoom siv ntxiv ntxiv rau cov pob zeb, polypropylene fiber ntau tuaj yeem txhim kho nws cov kev ua haujlwm tawg, impermeability, kev cuam tshuam, av qeeg tsis kam, Frost tsis kam, yaig tsis kam, tawg tsis kam, kev laus ua haujlwm thiab kev ua haujlwm, twj tso kua mis, thiab dej tuav.poj niam deev.
● Tiv thaiv kev tsim cov pob zeb tawg
● Txhim kho qhov kev tiv thaiv permeability ntawm pob zeb
● Txhim kho qhov khov-thaw tsis kam ntawm pob zeb
● Txhim kho qhov cuam tshuam tsis kam, flexural tsis kam, qaug zog ua haujlwm thiab seismic kev ua tau zoo ntawm pob zeb
● Txhim kho lub durability thiab aging kuj ntawm pob zeb
● Txhim kho qhov hluav taws kub ntawm cov pob zeb

Cov cheeb tsam thov:
Qhob txhav self-waterproof qauv:
Hauv pem teb pem teb, sab phab ntsa, ru tsev, ru tsev cam khwb cia-nyob rau hauv-qhov chaw slab, reservoir, thiab lwm yam Engineering, dej conservancy tej yaam num, subways, tshav dav hlau runways, chaw nres nkoj terminals, overpass viaduct decks, piers, super-ntev qauv nrog siab yuav tsum tau rau tawg kuj. , cuam tshuam tsis kam, thiab hnav tsis kam.

Cement Mortar:
Sab hauv (sab nrauv) phab ntsa painting, aerated qhob plastering, kho kom zoo nkauj sab hauv putty thiab thermal rwb thaiv tsev mortar.
Anti-explosion thiab hluav taws-resistant engineering:
Civil tiv thaiv tub rog tej yaam num, roj platforms, chimneys, refractory khoom, thiab lwm yam.

Shotcrete:
Tunnel, culvert hauv ob sab phlu, nyias-walled qauv, nqes hav reinforcement, thiab lwm yam.
Cov lus qhia rau kev siv
Pom zoo noj ntau npaum:
Qhov pom zoo tus nqi ntawm mortar ib square ntawm zoo tib yam plastering mortar yog 0.9 ~ 1.2kg
Qhov pom zoo tus nqi ntawm thermal rwb thaiv tsev mortar ib tuj: 1 ~ 3kg
Qhov pom zoo ntawm pob zeb rau ib lub cubic meter ntawm pob zeb yog: 0.6 ~ 1.8kg (rau siv)

Kev tsim kho tshuab thiab cov kauj ruam
① Raws li qhov ntim ntawm cov pob zeb sib xyaw txhua lub sijhawm, qhov hnyav ntawm cov fiber ntau ntxiv txhua lub sijhawm raug ntsuas raws li qhov xav tau ntawm qhov sib xyaw ua ke (los yog qhov pom zoo sib xyaw).
② Tom qab npaj cov xuab zeb thiab gravel, ntxiv cov fiber ntau.Nws raug nquahu kom siv lub tshuab sib xyaw ua ke.Ntxiv cov aggregate ua ke nrog cov fiber ntau rau hauv lub tov khoom, tab sis ua tib zoo xyuas kom meej tias cov fiber ntau ntxiv ntawm cov khoom sib xyaw thiab sib tov kom qhuav li 30 vib nas this.Tom qab ntxiv dej, sib tov nws ntub dej li 30 vib nas this kom tag nrho cov fiber ntau disperse.
③ Coj mus kuaj tam sim tom qab sib tov.Yog tias cov fibers tau sib npaug sib npaug rau hauv monofilaments, cov pob zeb tuaj yeem muab tso rau hauv kev siv.Yog tias tseem muaj cov khoom siv fiber ntau, txuas lub sijhawm sib xyaw los ntawm 20-30 vib nas this ua ntej siv.
④ Kev tsim kho thiab tu txheej txheem ntawm fiber ntau ntxiv pob zeb yog tib yam li cov pob zeb zoo tib yam.Npaj siv.
