Mechanism o ka hana o ka basalt fibers in asphalt

1、Adsorption a me ka hoʻonui viscosity o nā fiber

ʻO ka fiber a me ka asphalt i hui pū ʻia me kahi ʻāpana kikoʻī nui loa, e hana ana i ka wahi i loko o ka pulu a me ka adsorption interface a me ka hoʻonui ʻana i ka viscosity. I ka papa mahele o ka ʻili fiber, hoʻonohonoho ʻia ka asphalt hoʻokahi mole e hana i kahi papa kuhikuhi asphalt, e lawe i ke kuleana o ka hoʻololi ʻana a me ka pale ʻana i ka asphalt a me ke koʻikoʻi fiber. Ma o ka ʻAla Basalt adsorption, stabilization, toughening, crack-blocking and viscosity-enhancing effects, hoʻokolohua hoʻokolohua o ke kuleana o ka basalt fibers i ka asphalt mixtures, a me ka nānā ʻana i nā kiʻi microscope electron i loaʻa ma ka scanning electron microscopy method e hōʻoia i ka ikaika o ka hiki adsorption o ka fiber. Napulu basaltasphalt Specimens ma waena o ka rupture ili i ka hoʻopaʻapaʻa, a ma hope o ke kahua emission kaiapuni scanning electron microscope ho'āʻo apparatus ohi i nā kiʻi, mai ka microscopic wahi o ka nānā 'ana i ka hana o ka māwae-kū kū'ē, e wehewehe ana i ka haʻahaʻa-mahana kū'ē i ka māwae nui hilinaʻi ma luna o ka hana o ka māwae-kū kū'ē.

2 、Hoʻokūpaʻa o nā fiber

Fibers i loko o ka asphalt hui 'ana i ekolu-dimensional dispersion moku'āina mahele, no laila, i ka noa asphalt i loko o ka hui 'ana e ho'ēmi i ka hapa o ka structural asphalt mahuahua, no laila, i ka viscosity o ka asphalt mortar mahuahua, i ka mahana paʻa ua hoʻomaikaʻi. Ma o ka noiʻi a me ka nānā ʻana, hōʻike nā hopena i ka hoʻohui ʻana o nā pulu basalt ma hope o ka hui asphalt o ka haʻahaʻa-mahana hana pohā i hoʻomaikaʻi nui ʻia, ka hoʻokumu ʻana o nā pulu basalt i loko o ka hoʻolālā pūnaewele ʻekolu, ʻoi aku ka maikaʻi o ka hoʻomohala ʻana i nā māwae i loko o nā hui asphalt i ka hoʻopaneʻe ʻana i ka hoʻomohala ʻana o ka hana holoʻokoʻa.

3、ʻO ka hoʻoikaika ʻana a me ka hopena paʻa ʻana o nā fiber

ʻO nā fibers i ka hui ʻana o ʻekolu-dimensional random distribution, ka hoʻokumu ʻia ʻana o ʻekolu-dimensional spatial grid structure, the asphalt mastic cracking play a crack-blocking, slowing down the crack development time, improve the performance of recycled asphalt pavement cracking resistance. ʻO kekahi mau mea noiʻi ma o ka nānā ʻana i nā hopena hōʻike, ua wehewehe i ka fiber i hui ʻia i ka hui asphalt ma hope o ka adsorption, stabilization, viscosity, reinforcement, crack-blocking effect, toughening effect, a me ka fiber e hoʻonui i ka hiki ke ho'ōla i ka hana o ka mīkini, nā hopena i loaʻa e ka fiber ma ka hui asphalt e hoʻomaikaʻi i ka hana o ka hopena anti-cracking.

Nā hualoaʻa noiʻi piha, ke kuleana o nā pulu basalt Hiki ke hōʻuluʻulu ʻia penei: ʻo nā fibers i loko o ka hui asphalt he ʻano like ʻole ʻekolu-dimensional mesh structure distribution, me ka hana tandem skeleton, i ka haʻi mua ʻana o ka hui asphalt e pāʻani i kahi kuleana i ka hohola ʻana, e pale ana i nā māwae mai ka hoʻonui hou ʻana.
