Mechanism ntawm Basalt Fiber hauv pob zeb

Qhob, raws li cov khoom nkig, feem ntau suav nrog cov fibers los txhim kho nws cov kev ua tau zoo. Lub mechanism ntawm Basalt Fiber ntau nyob rau hauv qhob feem ntau manifests nyob rau hauv cov nram qab no yam.

1.Crack Inhibition thiab Bridging nyhuv

Raws li qhov kev xav ntawm fiber ntau qhov sib txawv thiab elastic fracture mechanics, basalt fibers txhim kho cov txheej txheem sab hauv ntawm pob zeb los ntawm kev sib cuam tshuam ntawm lub cev-mechanical. Thaum lub sij hawm hardening shrinkage thiab noo noo evaporation ntawm cov pob zeb, cov fibers no zoo inhibit qhov pib thiab nthuav tawm ntawm qhov ntxov-theem ziab shrinkage microcracks thiab cais cov kab nrib pleb, yog li tiv thaiv kev tawg ntxiv. Qhov no tseem ceeb txhim kho qhov tawg tsis kam thiab impermeability ntawm pob zeb. Tsis tas li ntawd, thaum cov kab nrib pleb tsim nyob rau hauv cov pob zeb matrix, basalt fibers txuas ob sab ntawm cov kab nrib pleb, ua rau cov khoom siv sab nraud thiab tiv thaiv cov pob zeb tawg tam sim ntawd. Qhov no mechanism txhim kho lub toughness thiab tawg tsis kam ntawm pob zeb.

2. Txhim kho cov cuab yeej cuab tam

Basalt fibers thiab cov pob zeb matrix sib koom ua ke dais sab nraud. Nyob rau hauv thawj theem loading, lub matrix bears feem ntau ntawm cov load. Thaum cov kab nrib pleb tsim nyob rau hauv cov matrix, cov fibers txuas ntxiv mus nqa lub nra, txhim kho lub peev xwm deformation ntawm pob zeb hauv theem yas. Cov kev tshawb fawb qhia tau hais tias kev sib koom ua ke ntawm basalt fibers ua rau muaj zog compressive, tensile zog, toughness, splitting tensile zog, thiab flexural tensile lub zog ntawm pob zeb.

3.Kev txhim kho ntawm Durability

Los ntawm kev sib txuas cov kab nrib pleb thiab txo lawv txoj kev tsim, basalt fibers txhim khu kev tiv thaiv Frost thiab kev cuam tshuam ntawm cov pob zeb, txhim kho qhov ua tau zoo ntawm cov pob zeb ua vaj tse. Tsis tas li ntawd, kev suav nrog cov fibers pom zoo txhim kho impermeability, Frost tsis kam, thiab ziab shrinkage zog, ncua kev pab cuam lub neej ntawm pob zeb nyob rau hauv ib puag ncig hnyav.

4.Microstructural Optimization

Basalt fiberscuam ​​tshuam nrog cov cement matrix dhau Tshuaj thiab lub cev bonds, tsim ib tug complex microstructure. Kev sib koom ua ke ntawm cov fibers hloov kho cov pob zeb ntawm microstructure thiab optimizes nws tus cwj pwm kev ntxhov siab, yog li txhim kho tag nrho cov kev ua tau zoo ntawm cov khoom.
