Polypropylene fibers (PP fibers) feem ntau yog siv los ua cov khoom siv dag zog hauv pob zeb los txhim kho nws cov khoom siv dag zog thiab kav ntev. Nov yog qee lub luag haujlwm tseem ceeb ntawm polypropylene fibers hauv pob zeb:

1. Crack Control: Ib lub luag haujlwm tseem ceeb ntawm PP fibers hauv pob zeb yog tswj kev tsim thiab nthuav tawm ntawm cov kab nrib pleb. Cov fibers no ua raws li micro-reinforcement thoob plaws hauv lub pob zeb matrix, pab faib kev ntxhov siab ntau dua thiab txo qis qhov tshwm sim ntawm kev tawg. Los ntawm kev tswj cov kab nrib pleb, PP fibers tuaj yeem txhim kho lub zuag qhia tag nrho durability thiab lifespan ntawm pob zeb lug.
2. Txhim kho Toughness thiab Ductility: Kev suav nrog PP fibers txhim khu lub toughness thiab ductility ntawm pob zeb. Cov fibers no muab lub zog tensile ntxiv rau cov qhob matrix, ua rau nws tiv taus ntau dua rau kev cuam tshuam thiab dynamic loading. Qhov kev txhim kho toughness no tuaj yeem muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov uas cov pob zeb ua rau muaj kev sib tsoo hnyav, kev ua seismic, lossis lwm yam kev ntxhov siab.
3. Txo Shrinkage Cracking: Shrinkage cracking yog ib qho teeb meem tshwm sim hauv cov pob zeb uas tshwm sim los ntawm kev poob dej thaum lub sij hawm kho. PP fibers pab txhawm rau txo qis kev tawg los ntawm kev txo qis tag nrho ntawm cov pob zeb thiab muab kev txhawb zog sab hauv uas tiv thaiv kev tawg.
4. Txhim kho Durability: PP fibers tuaj yeem txhim kho qhov ua tau zoo ntawm cov qauv pob zeb los ntawm kev txo qis qhov tshwm sim ntawm kev tawg thiab ua rau muaj kev tiv thaiv ib puag ncig xws li khov-thaw mus, tshuaj lom neeg, thiab puas. Qhov kev txhim kho durability no tuaj yeem ua rau lub neej ua haujlwm ntev dua thiab txo cov kev xav tau ntawm kev saib xyuas rau cov vaj tse pob zeb.
5. Tswj cov yas Shrinkage Cracking: Nyob rau hauv cov qhob tshiab, evaporation sai ntawm cov av noo tuaj yeem ua rau cov yas shrinkage tawg. PP fibers pab tswj cov yas shrinkage cracking los ntawm kev muab kev txhawb zog rau cov pob zeb thaum ntxov, ua ntej nws tau kho tag nrho thiab tau txais lub zog txaus los tiv thaiv kev tawg.
6. Kev Txhim Kho Hluav Taws Xob: Polypropylene fibers tuaj yeem txhim kho qhov hluav taws kub ntawm cov pob zeb los ntawm kev txo qis, uas tshwm sim thaum nto ntawm pob zeb tawg lossis flakes tawm vim cua sov sai. Cov fibers pab khi cov pob zeb ua ke kom zoo dua qub, tiv thaiv kev nthuav tawm ntawm cov kab nrib pleb thiab txo qhov kev pheej hmoo ntawm kev tawg thaum hluav taws.
7. Yooj yim ntawm kev tuav thiab sib tov: PP fibers yog lub teeb yuag thiab yooj yim dispersible nyob rau hauv cov pob zeb sib tov, ua rau lawv ncaj nraim mus lis thiab sib tov rau ntawm qhov chaw. Qhov yooj yim ntawm kev tuav no pab txhawb kev sib koom ua ke ntawm cov fibers rau hauv pob zeb yam tsis muaj kev hloov pauv tseem ceeb rau txoj kev tsim kho.

Zuag qhia tag nrho, polypropylene fibers ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm, kev ua haujlwm ntev, thiab kev ua haujlwm ntawm cov pob zeb ua vaj tse, ua rau lawv muaj txiaj ntsig zoo hauv ntau hom kev tsim kho.
