PP fiber ntau yog dab tsi?

PP fiber ntaustands rau polypropylene fiber, uas yog ib tug hluavtaws fiber ntau ua los ntawm polymerized propylene.Nws yog cov khoom siv ntau yam nrog ntau yam kev siv hauv kev lag luam xws li textiles, automotive, kev tsim kho, thiab ntim khoom.Hauv cov ntsiab lus ntawm kev tsim kho, PP fibers feem ntau yog siv los ua cov khoom siv ntxiv hauv cov pob zeb los txhim kho nws cov khoom thiab kev ua haujlwm.Ntawm no yog cov ntsiab lus ntawm PP fiber ntau:

Cov khoom ntawm PP Fiber:

1. Lub zog: PP fibers muaj lub zog tensile siab, uas ua rau lub zog ntawm cov pob zeb thiab txhim kho nws tag nrho cov kav ntev thiab tsis kam tawg.
2. Flexibility: PP fibers hloov tau yooj yim thiab tuaj yeem sib xyaw ua ke hauv cov pob zeb sib xyaw tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov pob zeb.
3. Tshuaj Tiv Thaiv: Polypropylene tiv taus ntau yam tshuaj, ua rau PP fibers haum rau siv nyob rau hauv hnyav ib puag ncig uas pob zeb yuav raug corrosive tshuaj.
4. Dej Resistance: PP fibers yog hydrophobic thiab tsis nqus dej, uas pab tiv thaiv kom txhob ya raws thiab deterioration ntawm pob zeb.
5. Lub teeb yuag: PP fibers yog lub teeb yuag, uas yooj yim rau kev tuav thiab sib xyaw cov txheej txheem thaum lub sij hawm ua vaj tse.
6. Thermal Stability: PP fibers muaj thermal stability zoo thiab tswj lawv cov khoom nyob rau ntau qhov kub thiab txias.

Kev siv ntawm PP Fiber hauv pob zeb:

1. Crack Control: PP fibers pab tswj cov yas shrinkage tawg hauv pob zeb los ntawm kev txo qhov tsim thiab nthuav tawm ntawm cov kab nrib pleb los ntawm kev ziab kom qhuav.
2. Impact Resistance: PP fibers txhim kho qhov cuam tshuam ntawm kev ua vaj tse, ua rau nws tsim nyog rau cov ntawv thov uas cuam tshuam kev thauj khoom muaj kev txhawj xeeb, xws li cov plag tsev thiab cov pavements.
3. Abrasion Resistance: Qhov sib ntxiv ntawm PP fibers txhim kho kev puas tsuaj ntawm cov pob zeb ua haujlwm, ua rau lawv lub neej ua haujlwm ntev hauv cov chaw tsheb loj.
4. Kev txhim kho ntawm Toughness: PP fibers nce lub toughness thiab ductility ntawm pob zeb, uas txhim kho nws lub peev xwm los tiv thaiv dynamic loading thiab seismic rog.
5. Shotcrete thiab Kho mortars: PP fibers yog siv rau hauv cov ntawv thov txhaj tshuaj thiab kho cov mortars los txhim kho lawv cov kev ua tau zoo thiab ua haujlwm ntev.
6. Fiber-Reinforced Concrete (FRC): PP fibers feem ntau siv ua ke nrog lwm hom fibers (piv txwv li, steel fibers) los tsim fiber ntau pob zeb nrog cov khoom siv zoo tshaj plaws.

Installation thiab Mixing:

• PP fibers feem ntau yog ntxiv rau cov pob zeb sib tov thaum lub sij hawm batching los yog sib tov, nyob rau hauv daim ntawv qhuav los yog pre-dispersed nyob rau hauv dej.
• Qhov ntau npaum ntawm PP fibers nyob ntawm qhov xav tau kev ua tau zoo ntawm cov pob zeb thiab feem ntau yog teev los ntawm cov chaw tsim khoom lossis tus kws ua haujlwm.
• Kev sib xyaw kom zoo yog qhov tseem ceeb los xyuas kom meej qhov sib txawv ntawm cov fibers thoob plaws hauv cov pob zeb ua matrix.

Xaus:

PP fiber reinforcement muaj ntau qhov zoo hauv kev tsim vaj tsev, nrog rau kev txhim kho kev sib tsoo, kev cuam tshuam, kev puas tsuaj, thiab toughness.Los ntawm kev sib koom ua ke PP fibers rau hauv kev sib xyaw ua ke, cov kws tsim khoom thiab cov neeg ua haujlwm tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov pob zeb ua vaj tse, ua rau kev txuag nqi thiab ua kom muaj zog ntxiv.
