Analysis ntawm lub mechanism ntawm kev txiav txim ntawm basalt fibers
1 Adsorption thiab viscosity li ntawm fibers
Basalt fibersmuaj qhov tshwj xeeb ntawm thaj chaw loj, uas ua rau lawv tsim ib qho kev cuam tshuam ntawm infiltration thiab adsorption hauv asphalt sib tov los txhim kho viscosity. Ntawm qhov sib cuam tshuam ntawm fiber ntau thiab asphalt, asphalt monomolecules tau teem rau hauv cov txheej txheem, piv txwv li lub luag haujlwm ntawm kev hloov pauv thiab kev ntxhov siab. Cov kev tshawb fawb ntsig txog tau pom tias Basalt Fiber ntaus muaj lub peev xwm adsorption muaj zog, uas ua kom cov viscosity ntawm asphalt sib tov. Qhov kev txhim kho viscosity no ua rau kev sib tshuam ntawm asphalt thiab fibers ruaj khov dua, yog li kev txhim kho tag nrho cov kev ua tau zoo ntawm asphalt sib tov.
2 Stabilizing nyhuv ntawm fibers
Hauv kev sib xyaw asphalt, basalt fibers muaj nyob rau hauv peb-dimensional dispersed lub xeev, txo qhov kev faib ua feem ntawm dawb asphalt thiab nce qhov feem ntawm cov qauv asphalt. Qhov kev hloov pauv no ua rau muaj viscosity ntawm asphalt mastic thiab txhim kho qhov kub thiab txias. Txoj kev tshawb no qhia tau hais tias qhov sib ntxiv ntawm basalt fibers zoo txhim kho qhov kub thiab txias tsis kam ntawm asphalt sib tov, thiab nws cov qauv peb-seem sib txuas ua haujlwm tau zoo ncua kev txhim kho ntawm cov kab nrib pleb thiab txhim kho kev ncaj ncees thiab tawg tsis kam ntawm cov khoom sib xyaw.
3 Reinforcement thiab Crack Resistance ntawm Fibers
Peb-dimensional spatial grid qauv tsim los ntawm basalt fibers nyob rau hauv lub mix plays lub luag hauj lwm tseem ceeb nyob rau hauv lub crack-resistant zog. Cov qauv tsis tsuas yog tiv thaiv kev nthuav dav ntxiv ntawm cov kab nrib pleb tab sis tseem ncua sij hawm txoj kev loj hlob ntawm cov kab nrib pleb. Cov txiaj ntsig ntawm txoj kev tshawb fawb qhia tau hais tias kev sib koom ua ke ntawm fibers ua rau txhim kho kev tawg ntawm asphalt sib tov thiab txhim kho lawv tus kheej muaj peev xwm kho tau.

Kev tshawb fawb tau zoo nyob hauv tsev thiab txawv teb chaws, lub luag haujlwm ntawm basalt fibers nyob rau hauv asphalt sib tov tuaj yeem raug sau tseg raws li hauv qab no: lawv muab faib rau hauv qhov sib xyaw ua ke nyob rau hauv qhov tsis sib xws ntawm peb-dimensional mesh qauv, nrog rau kev ua haujlwm ntawm lub cev pob txha tandem. Thaum pib tawg ntawm asphalt sib tov, basalt fibers muaj txiaj ntsig tiv thaiv kev nthuav dav ntxiv ntawm cov kab nrib pleb los ntawm cov nyhuv tensile, yog li txhim kho tag nrho cov kev ua tau zoo ntawm asphalt sib tov. Cov txiaj ntsig zoo no ua rau cov fibers basalt yog ib feem tseem ceeb ntawm cov ntaub ntawv hloov kho asphalt thiab muaj kev cuam tshuam zoo rau kev txhim kho cov kav ntev thiab kev nyab xeeb ntawm txoj kev.
