Mechanism ntawm kev ua haujlwm ntawm basalt fibers hauv asphalt
1,Kev txhim kho adsorption thiab viscosity ntawm cov fibers
Fiber thiab asphalt sib xyaw nrog thaj chaw loj heev, ua rau thaj chaw ntawd mus rau hauv qhov ntub thiab adsorption interface thiab viscosity txhim kho. Hauv txheej faib ntawm qhov chaw fiber, asphalt ib qho molecule kev npaj los tsim ib txheej asphalt interface, dais lub luag haujlwm ntawm kev hloov pauv thiab buffering asphalt thiab fiber kev ntxhov siab. Los ntawm Basalt Fiber kev nqus, kev ruaj khov, kev tawv, kev thaiv kab nrib pleb thiab kev txhim kho viscosity, kev tshuaj xyuas kev sim ntawm lub luag haujlwm ntawm cov fibers basalt hauv cov khoom sib xyaw asphalt, thiab cov duab scanning electron microscope tau los ntawm txoj kev scanning electron microscopy lees paub tias lub fiber lub peev xwm nqus tau muaj zog. Los ntawmbasalt fiberasphalt Cov Qauv Siv Ua Vaj TseCov kev sib txuas ntawm qhov tawg ntawm qhov chaw hauv kev nruj, thiab tom qab qhov chaw tso tawm hauv thaj chaw scanning electron microscope kuaj cov cuab yeej sau cov duab, los ntawm qhov pom ntawm microscopic los tshuaj xyuas lub luag haujlwm ntawm qhov tawg-resistant, piav qhia txog qhov kub qis-kub tiv taus kev tawg feem ntau nyob ntawm lub luag haujlwm ntawm qhov tawg-resistant.
2,Kev ruaj khov ntawm cov fibers
Cov fibers hauv cov asphalt sib tov rau peb-dimensional dispersion xeev faib, yog li ntawd cov asphalt dawb hauv cov sib tov kom txo qhov sib piv ntawm cov qauv asphalt nce, yog li ntawd qhov viscosity ntawm asphalt mortar nce, qhov kub thiab txias tau zoo dua. Los ntawm kev tshawb fawb thiab kev tsom xam, cov txiaj ntsig qhia tau tias qhov ntxiv ntawm cov fiber basalt tom qab cov asphalt sib xyaw ntawm qhov kub qis cracking kev ua tau zoo tau zoo dua, kev tsim ntawm cov fiber basalt nyob rau hauv peb-dimensional network qauv, txoj kev loj hlob ntawm cov kab nrib pleb hauv asphalt sib xyaw ua lub luag haujlwm zoo hauv kev ncua kev loj hlob ntawm tag nrho cov kev ua tau zoo tau ua lub luag haujlwm tiv thaiv zoo dua.
3,Kev txhawb zog thiab kev thaiv kev tawg ntawm cov fibers
Cov fibers hauv qhov sib xyaw ntawm peb-seem random faib, kev tsim ntawm peb-seem spatial grid qauv, asphalt mastic cracking ua si ib qho tawg-blocking, qeeb lub sijhawm tsim kho tawg, txhim kho kev ua tau zoo ntawm kev siv asphalt pavement cracking tsis kam. Qee cov kws tshawb fawb los ntawm kev tshuaj xyuas cov txiaj ntsig xeem, feem, piav qhia txog cov fiber sib xyaw rau hauv asphalt sib xyaw tom qab adsorption, stabilization, viscosity, reinforcement, tawg-blocking nyhuv, toughening nyhuv, nrog rau cov fiber kom nce lub peev xwm los kho lub luag haujlwm ntawm lub mechanism, cov txiaj ntsig tau los ntawm cov fiber ntawm asphalt sib xyaw kom txhim kho kev ua tau zoo ntawm cov nyhuv tiv thaiv kev tawg yog qhov tseem ceeb.
Cov txiaj ntsig tshawb fawb tiav, lub luag haujlwm ntawm cov fiber basalt tuaj yeem sau ua ke raws li nram no: cov fibers hauv cov asphalt sib tov yog qhov tsis sib xws peb-seem mesh qauv faib, nrog rau lub cev pob txha tandem, thaum pib tawg ntawm asphalt sib tov ua lub luag haujlwm hauv kev ncab, tiv thaiv cov kab nrib pleb los ntawm kev nthuav dav ntxiv.
