Ndemanga ya maphunziro osintha pamwamba pa ulusi wa basalt

Monga chinthu chochita bwino kwambiri cha fiber, basalt fiber ndi makina abwino kwambiri, Chemical kukana, ndi kukhazikika kwa kutentha kwachititsa kuti pakhale ntchito zosiyanasiyana mu zomangamanga, zipangizo zophatikizika, ndi kuteteza chilengedwe. Komabe, ulusi wa basalt umakhala ndi malo osalala komanso alibe magulu ogwira ntchito, zomwe zimapangitsa kuti pakhale mgwirizano wosagwirizana ndi zida za matrix. Chifukwa chake, kusinthidwa kwapamwamba kwa ulusi wa basalt kumatha kupititsa patsogolo kwambiri mawonekedwe awo omangirira komanso kupititsa patsogolo ntchito zawo m'magulu ophatikizika komanso chitetezo cha chilengedwe. Zotsatirazi ndikupita patsogolo kwa kafukufuku wa njira zingapo zazikulu zosinthira.

1. Silane coupling agent pamwamba kusinthidwa

Silane coupling agent ndi mankhwala omwe amagwiritsidwa ntchito kwambiri padziko lapansi omwe amawongolera mawonekedwe olumikizana pakati pa ulusi ndi zida za matrix kudzera polumikizana ndi mankhwala.

Kusintha kwa KH-550

Kafukufukuyu akuwonetsa kuti kuchitira ulusi wa basalt ndi silane coupling agent KH-550 yankho kumapanga zomangira zokhazikika zamakemikolo pamtunda wa fiber ndikuwongolera kulumikizana pakati pa ulusi ndi phula. Mlingo woyenera wa KH-550 ndi 1.0%, ndipo nthawi ya chithandizo ndi mphindi 30. Pambuyo pa kusinthidwa, kumamatira pakati pa basalt fiber ndi asphalt kunasinthidwa ndi 1 kalasi. Kuchuluka kwa mayamwidwe amafuta kudakwera ndi 65.5%, zomwe zidakulitsa kwambiri kumamatira ndi phula.

Mtengo wa KH-570 Kusintha

KH-570 imasintha ulusi wa basalt kuti ukhale wowuma pamwamba pawo ndikuwonjezera zomwe zimagwira ntchito pamtunda. Muzinthu zophatikizika, pakuwonjezeka kwa kutalika kwa ulusi wosinthidwa komanso kuchuluka kwake, makina amakina azinthu zophatikizika amakhala bwino kwambiri.

2. Kusintha kwapamwamba

Kusintha kwa mtengo wa CTAC

Kupaka kwakuthupi kwa ulusi wa basalt wokhala ndi cationic surfactant cetyltrimethylammonium chloride (CTAC) kumapangitsa hydrophilicity ndi dispersibility wa ulusi m'madzi. Njira yosinthira iyi imakhudza kwambiri kumamatira kwa filimu ya tizilombo tating'onoting'ono: mphamvu yomata ya tizilombo imakula kwambiri. Kuchulukitsa kuchuluka kwa tizilombo toyambitsa matenda kumathandizira kugwiritsa ntchito madzi otayira.

3. Organic chitsulo madzimadzi gawo mafunsidwe kusinthidwa

Kusintha kwa ulusi wa basalt ndi organic iron liquid phase deposition kumatha kupititsa patsogolo luso lazomatira la fiber pamwamba ndikupititsa patsogolo kugwiritsa ntchito kwake pakuyeretsa madzi oyipa. Njira yosinthira iyi imatha kupanga zokutira zokhazikika za iron oxide pamwamba pa ulusi kuti ziwongolere kutulutsa kwake komanso kuwononga zowononga.

4. Kusintha kwa zokutira ndi nano-silica

Nanosilica particles ali uniformly omwazika mu infiltrant kapena kubalalitsidwa, ndipo akhoza basalt CHIKWANGWANI ❖ kuyanika kusinthidwa: pakati basalt CHIKWANGWANI ndi epoxy utomoni, nanosilica particles ntchito mlatho, kwambiri kuwongolera interfacial ngakhale pakati pa awiri. Pambuyo pa kusinthidwa, kuuma kwapamwamba kwa basalt fiber kumawonjezeka, malo enieni akuwonjezeka, ndipo magulu ogwira ntchito omwe ali ndi okosijeni amawonjezeka. Kafukufukuyu adawonetsa kuti pogwiritsa ntchito chonyamulira cha nanosilica-modified basalt fiber: kuchuluka kwenikweni kwa filimu ya tizilombo tating'onoting'ono pa gramu ya CHIKWANGWANI chokwera chinawonjezeka ndi 21,39%. Kuchotsa zonyansa kunali bwino kwambiri.

Pomaliza ndi Outlook

Zochita zapamtunda, zomangira zolumikizirana komanso magwiridwe antchito a ulusi wa basalt zidasinthidwa kwambiri ndi njira zosiyanasiyana zosinthira pamwamba. Mwa iwo:

1. Silane coupling agent kusinthidwa ndikoyenera kwambiri kuwongolera kumamatira kwa ulusi wa basalt ndi zinthu za masanjidwewo (mwachitsanzo simenti, phula, epoxy resin, etc.).
2. Kusinthidwa kwa surfactant ndi organic iron deposition kusinthidwa ndikoyenera kwambiri pachitetezo cha chilengedwe, makamaka pakugwiritsa ntchito tizilombo toyambitsa matenda pochotsa zimbudzi.
3. Kusintha kwa zokutira za Nano-silica, ndi zabwino zowonjezera makina ndi magwiridwe antchito, kuli ndi chiyembekezo chosiyanasiyana pankhani ya Zinthu Zophatikiza ndi kuteteza chilengedwe.

Kafukufuku wamtsogolo atha kupititsa patsogolo njira zosinthira ndikuwunika momwe njira zosinthira zimagwirira ntchito kuti zikwaniritse zosowa za mapulogalamu osiyanasiyana.
