Mechanism ntawm kev ua ntawm basalt fibers hauv asphalt
1,Adsorption thiab viscosity txhim kho cov fibers
Fiber thiab asphalt sib xyaw nrog thaj chaw loj heev, ua rau thaj chaw ntub dej thiab adsorption interface thiab viscosity li qub. Nyob rau hauv kev faib txheej ntawm fiber ntau nto, asphalt ib leeg molecule kev npaj los tsim cov txheej txheem asphalt interface txheej, dais lub luag hauj lwm ntawm kev hloov thiab buffering asphalt thiab fiber ntau kev nyuaj siab. Los ntawm Basalt Fiber ntau adsorption, stabilization, toughening, crack-blocking thiab viscosity-txhim kho cov teebmeem, kev sim tsom xam lub luag hauj lwm ntawm basalt fibers hauv asphalt mixs, thiab scanning electron microscope dluab tau los ntawm scanning electron microscopy txoj kev paub meej tias cov fiber ntau adsorption muaj zog. Los ntawmbasalt fiber ntauasphalt Pob zeb Specimens nruab nrab ntawm lub rupture nto nyob rau hauv nro, thiab tom qab lub teb emission ib puag ncig scanning electron microscope kuaj apparatus sau dluab, los ntawm lub microscopic taw tes ntawm view los soj ntsuam lub luag hauj lwm ntawm lub crack-resistant, piav qhia qhov kub-kub tsis kam mus tawg mas nyob ntawm lub luag hauj lwm ntawm lub crack-resistant.
2,Stabilization ntawm fibers
Fibers nyob rau hauv asphalt sib tov rau peb-dimensional dispersion lub xeev faib, kom cov dawb asphalt nyob rau hauv lub sib tov kom txo tau qhov feem ntawm cov asphalt structural nce, kom lub viscosity ntawm asphalt mortar nce, qhov kub thiab txias stability tau zoo tuaj. Los ntawm kev tshawb fawb thiab kev tsom xam, cov txiaj ntsig tau qhia tias qhov sib ntxiv ntawm basalt fibers tom qab asphalt sib tov ntawm qis-kub cracking kev ua tau zoo tau txhim kho, tsim ntawm basalt fibers nyob rau hauv peb-dimensional network qauv, txoj kev loj hlob ntawm cov kab nrib pleb nyob rau hauv asphalt mixtures plays lub luag hauj lwm zoo nyob rau hauv ncua kev loj hlob ntawm tag nrho cov kev ua tau zoo tau ua lub luag hauj lwm tiv thaiv zoo dua.
3,Kev txhawb zog thiab tawg-thaiv cov nyhuv ntawm fibers
Fibers nyob rau hauv kev sib tov ntawm peb-dimensional random faib, tsim ntawm peb-dimensional spatial grid qauv, lub asphalt mastic cracking ua si ib tug tawg-thaiv, slowing down lub sij hawm tawg, txhim kho cov kev ua tau zoo ntawm recycled asphalt pavement cracking kuj. Qee cov kws tshawb fawb los ntawm kev txheeb xyuas cov txiaj ntsig ntawm kev soj ntsuam, raws li tau piav qhia txog cov fiber ntau sib xyaw rau hauv asphalt sib tov tom qab adsorption, stabilization, viscosity, reinforcement, crack-blocking effect, toughening effect, as well as the fiber toughening effect, as well as the fiber to improve the ability to heal the role of the mechanism, cov txiaj ntsig tau txais los ntawm fiber ntau ntawm asphalt sib tov - cracking nyhuv tseem ceeb ntawm kev ua haujlwm.
Kev tshawb fawb tau zoo, lub luag haujlwm ntawm basalt fibers Nws tuaj yeem raug sau tseg raws li hauv qab no: fibers hauv asphalt sib tov yog qhov tsis sib xws ntawm peb-dimensional mesh qauv faib, nrog rau lub cev pob txha muaj nuj nqi, hauv qhov pib tawg ntawm asphalt sib tov los ua lub luag haujlwm hauv kev ncab, tiv thaiv cov kab nrib pleb los ntawm kev nthuav dav ntxiv.
