Lub hom phiaj ntawm kev ntxiv fiber ntau hauv pob zeb yog dab tsi?

Ntxiv fibers rau pob zeb ua haujlwm ntau lub hom phiaj thiab tuaj yeem txhim kho kev ua haujlwm thiab cov khoom ntawm pob zeb hauv ntau txoj hauv kev:

1. Tswj kev tawg:

• Fiber reinforcement pab tswj kev tsim thiab nthuav tawm ntawm cov kab nrib pleb hauv pob zeb. Cov fibers ua raws li micro-reinforcements, bridging hla cov kab nrib pleb thiab txwv kev tawg qhov dav, yog li txhim kho tag nrho cov kav ntev thiab kev pabcuam ntawm cov pob zeb.

2. Nce Flexural Strength:

• Fiber reinforcement nce lub zog flexural thiab toughness ntawm pob zeb, tshwj xeeb tshaj yog nyob rau hauv nro. Qhov no tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv cov ntawv thov uas cov pob zeb raug khoov lossis flexural loads, xws li hauv pavements, pem teb, thiab choj decks.

3. Impact Resistance:

• Fibers txhim kho qhov cuam tshuam tsis kam ntawm pob zeb los ntawm kev nqus thiab rov faib lub zog thaum muaj kev cuam tshuam. Cov cuab yeej no yog ib qho tseem ceeb hauv cov qauv uas cuam tshuam rau cov khoom thauj, xws li cov plag tsev, chaw nres tsheb, thiab cov khoom tawg-resistant.

4. Txo Shrinkage thiab Curling:

• Fiber reinforcement pab txo shrinkage cracking thiab txo qhov nyiam ntawm pob zeb slabs rau curl. Los ntawm kev muab kev tuav pov hwm sab hauv, fibers txo qhov cuam tshuam ntawm kev hloov pauv cuam tshuam nrog kev ziab kom qhuav, qhov kub thiab txias hloov pauv, thiab qhov sib txawv ntawm cov dej noo.

5. Enhanced Toughness thiab Ductility:

• Fibers txhim kho lub toughness thiab ductility ntawm pob zeb, tso cai rau nws kom zoo dua tiv thaiv tam sim ntawd loading txheej xwm thiab post-cracking deformations. Qhov no muaj txiaj ntsig zoo hauv cov qauv seismic-resistant thiab hauv cov ntawv thov uas xav tau kev txhim kho cov qauv kev ntseeg siab.

6. Kev tswj cov yas Shrinkage Cracking:

• Fibers tuaj yeem pab tswj cov yas shrinkage cracking los ntawm kev txo cov dej evaporation thiab muab kev txhawb nqa thaum ntxov. Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kub los yog cua txias qhov twg sai sai ya raws los ntawm cov pob zeb nto yuav ua rau tawg.

7. Kev sib tsoo:

• Fibers ua raws li kev sib tsoo-txhim kho cov ntsiab lus, hla hla cov kab nrib pleb uas tuaj yeem txhim kho vim muaj ntau yam xws li ziab shrinkage, thermal gradients, lossis cov khoom thauj khoom. Qhov no pab tswj cov txheej txheem kev ncaj ncees thiab tiv thaiv kev tawg tawm.

8. Txhim kho Durability:

• Qhov sib ntxiv ntawm cov fibers tuaj yeem txhim kho qhov ua tau zoo ntawm cov pob zeb los ntawm kev txo cov ingress ntawm cov khoom tsis zoo xws li chlorides, sulfates, thiab lwm yam aggressive agents. Qhov no ua rau muaj zog tiv thaiv corrosion, tshuaj tua kab mob, thiab khov-thaw mus.

9. Kev tswj cov yas daws teeb meem tawg:

• Fibers pab tswj cov yas sib tsoo tawg los ntawm kev muab kev txhawb nqa sab hauv thiab ntxiv dag zog rau cov pob zeb tshiab thaum muab tso rau thiab sib sau ua ke. Qhov no minimizes kev sib haum xeeb sib txawv thiab txo qhov kev pheej hmoo ntawm tawg tsim.

10. Txhim khu kev tiv thaiv hluav taws:

• Qee hom fibers, xws li steel lossis polypropylene fibers, tuaj yeem txhim kho qhov hluav taws kub ntawm cov pob zeb los ntawm kev muab kev txhawb zog ntxiv ntawm qhov kub siab. Qhov no yog qhov tseem ceeb hauv cov qauv hluav taws kub thiab cov ntawv thov kev tiv thaiv hluav taws.

Hauv cov ntsiab lus, ntxiv cov fibers rau cov pob zeb muaj ntau yam txiaj ntsig, suav nrog kev txhim kho kev sib tsoo, ua kom lub zog muaj zog, txhim kho kev cuam tshuam, txo qis thiab curling, txhim kho toughness thiab ductility, tswj cov yas shrinkage thiab kev sib haum xeeb tawg, txhim kho durability, thiab txhim khu kev tiv thaiv hluav taws. Cov txiaj ntsig no ua rau fiber ntau cov pob zeb ua kom haum rau ntau yam ntawm cov txheej txheem thiab tsis yog cov qauv siv hauv kev tsim kho.
