Synthetic Fibers Concrete: Dab tsi, yog vim li cas, yuav ua li cas, hom & 4 lub tswv yim

Synthetic fibers yog siv rau hauv pob zeb los txhim kho nws cov khoom thiab ua kom nws ruaj khov. Cov fibers no yog tsim los ntawm ntau yam ntaub ntawv, xws li polypropylene, nylon, thiab polyester. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi hluavtaws fibers, yog vim li cas lawv siv nyob rau hauv pob zeb, yuav ua li cas lawv ntxiv, ntau hom muaj, thiab ib co tswv yim rau siv lawv zoo.

Dab tsi yog cov hluavtaws fibers hauv pob zeb?

Synthetic fibers yog luv luv, discrete, thiab randomly oriented fibers uas ntxiv rau pob zeb los txhim kho nws cov khoom. Lawv yog tsim los ntawm hluavtaws polymers, xws li polypropylene, nylon, thiab polyester, thiab feem ntau yog ntxiv rau me me rau cov pob zeb sib tov. Synthetic fibers yog siv nyob rau hauv qhov chaw ntawm tsoos steel reinforcing tuav los yog mesh.

Vim li cas cov hluavtaws fibers siv hauv pob zeb?

Synthetic fibers yog siv rau hauv pob zeb los txhim kho nws cov khoom thiab ua kom nws ruaj khov. Cov fibers txhim kho lub zog tensile, lub zog flexural, thiab toughness ntawm cov pob zeb, ua rau nws tiv taus ntau dua rau kev tawg thiab tawg. Synthetic fibers kuj tseem tuaj yeem pab tswj cov shrinkage cracking thiab txo tus nqi ntawm cov yas nyob hauv cov pob zeb. Tsis tas li ntawd, kev siv cov khoom siv hluavtaws tuaj yeem txo cov sijhawm thiab kev ua haujlwm uas yuav tsum tau ua los txhim kho cov khoom siv dag zog los yog mesh.

Yuav ua li cas yog hluavtaws fibers ntxiv rau pob zeb?

Synthetic fibers feem ntau yog ntxiv rau cov pob zeb sib tov thaum lub sij hawm batching. Cov fibers yog thawj zaug tov nrog dej kom disperse lawv tusyees thiab tiv thaiv clumping. Cov fiber-dej sib tov yog ces ntxiv rau lub pob zeb tov nrog rau lwm cov khoom xyaw. Cov txheej txheem sib tov faib cov fibers sib npaug thoob plaws hauv qhov sib xyaw ua ke.

Hom hluavtaws fibers hauv pob zeb:

Muaj ntau ntau hom hluavtaws fibers uas tuaj yeem siv rau hauv pob zeb. Nov yog qee yam ntawm ntau hom:

1. Polypropylene fibers: Polypropylene fibers yog feem ntau siv hluavtaws fibers hauv pob zeb. Lawv muaj peev xwm tiv taus alkali thiab muab kev cuam tshuam zoo thiab ua haujlwm ntev.
2. Nylon fibers: Nylon fibers kim dua polypropylene fibers tab sis muaj zog tensile ntau dua thiab modulus ntawm elasticity. Lawv tau siv rau hauv cov ntawv thov kev ntxhov siab, xws li choj decks thiab tshav dav hlau khiav.
3. Polyester fibers: Polyester fibers yog siv nyob rau hauv daim ntaub ntawv uas siab durability thiab kuj rau UV rays yuav tsum tau. Lawv feem ntau siv nyob rau hauv precast qhob khoom thiab architectural panels.
4. Hybrid fibers: Hybrid fibers yog kev sib xyaw ntawm ob lossis ntau hom hluavtaws fibers. Lawv muab kev sib xyaw ua ke ntawm cov khoom sib luag thiab tuaj yeem siv rau hauv ntau hom kev siv.

Cov lus qhia rau kev siv hluavtaws fibers hauv pob zeb:

Nov yog qee cov lus qhia rau kev siv hluavtaws fibers hauv pob zeb kom zoo:

1. Xaiv hom fiber ntau: Hom fiber ntau siv yuav tsum yog raws li daim ntawv thov thiab cov khoom xav tau.
2. Ua raws li cov chaw tsim khoom cov lus pom zoo: Cov chaw tsim khoom cov lus qhia rau ntau npaum li cas, sib tov, thiab tuav yuav tsum ua tib zoo ua raws.
3. Siv cov qauv sib xyaw kom raug: Cov qauv sib xyaw ua ke yuav tsum tau ua kom zoo rau cov ntawv thov tshwj xeeb thiab hom fiber ntau.
4. Xyuas kom muaj kev sib xyaw thiab kev tso kawm kom zoo: Cov fibers yuav tsum tau muab sib xyaw kom zoo rau hauv cov pob zeb thiab sib npaug sib npaug thoob plaws qhov sib tov. Ua tib zoo tso thiab compaction ntawm cov pob zeb yuav pab kom ntseeg tau tias cov fibers sib npaug sib npaug.

Hauv kev xaus, cov hluavtaws fibers yog siv hauv pob zeb los txhim kho nws cov khoom thiab ua kom nws ruaj khov. Lawv tau ntxiv rau cov pob zeb sib tov thaum lub sij hawm batching thiab tuaj nyob rau hauv ntau hom, xws li polypropylene, nylon, thiab polyester. Xaiv hom fiber ntau zoo, ua raws li cov chaw tsim khoom cov lus pom zoo, siv cov qauv sib xyaw kom raug, thiab ua kom muaj kev sib xyaw thiab kev tso kawm yog qhov tseem ceeb rau kev siv cov khoom siv hluavtaws hauv cov pob zeb ua kom zoo. Los ntawm kev siv cov hluavtaws fibers hauv pob zeb, cov neeg cog lus tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm lawv cov pob zeb ua vaj tse.
