Kuwunikanso kafukufuku wokhudza kusintha kwa pamwamba pa ulusi wa basalt
Monga ulusi wachilengedwe wochita bwino kwambiri, ulusi wa basalt umakhala ndi mphamvu zabwino kwambiri zamagetsi, Mankhwala Kukana, komanso kukhazikika kwa kutentha kwambiri kwapangitsa kuti pakhale ntchito zosiyanasiyana mu uinjiniya wa zomangamanga, zipangizo zophatikizika, komanso kuteteza chilengedwe. Komabe, ulusi wa basalt uli ndi malo osalala ndipo ulibe magulu ogwira ntchito, zomwe zimapangitsa kuti pakhale zovuta zolumikizirana pakati pa zinthu ndi zinthu zophatikizika. Chifukwa chake, kusintha pamwamba pa ulusi wa basalt kumatha kusintha kwambiri mawonekedwe awo olumikizirana pakati pa zinthu ndikuwonjezera kugwiritsa ntchito kwawo m'magawo ophatikizika ndi oteteza chilengedwe. Izi ndi zomwe zachitika pofufuza njira zingapo zazikulu zosinthira.
- Kusintha kwa pamwamba pa chinthu cholumikizira cha Silane
Cholumikizira cha silane ndi chothandizira chomwe chimagwiritsidwa ntchito kwambiri pochiza pamwamba chomwe chimawongolera mphamvu zolumikizirana pakati pa ulusi ndi zinthu za matrix kudzera mu cholumikizira cha mankhwala.
Kusintha kwa KH-550
Kafukufukuyu akuwonetsa kuti kuchiza ulusi wa basalt ndi silane coupling agent KH-550 solution kumapanga ma bond okhazikika a mankhwala pamwamba pa ulusi ndipo kumathandizira kuti mgwirizano pakati pa ulusi ndi phula ukhale wabwino. Kuchuluka koyenera kwa KH-550 ndi 1.0%, ndipo nthawi yochizira ndi mphindi 30. Pambuyo posintha, kuphatikizika pakati pa ulusi wa basalt ndi phula kunakula ndi 1 grade. Kuchuluka kwa kuyamwa kwa mafuta kunawonjezeka ndi 65.5%, zomwe zinawonjezera kwambiri kuphatikizika ndi phula.
KH-570 Kusintha
KH-570 imasintha ulusi wa basalt kuti ukhale wolimba pamwamba pake ndikuwonjezera mfundo zogwira ntchito pamwamba pa ulusi. Mu zinthu zophatikizika, ndi kuwonjezeka kwa kutalika kwa ulusi wosinthidwa ndi kuchuluka kwa kuwonjezera, mphamvu zamakina za zinthu zophatikizika zimawonjezeka kwambiri.
- Kusintha kwa surfactant
Kusintha kwa CTAC
Kuphimba ulusi wa basalt ndi cationic surfactant cetyltrimethylammonium chloride (CTAC) kumathandiza kuti ulusiwo usamafalikire komanso kuti utuluke m'madzi. Njira yosinthirayi imakhudza kwambiri kumatirira kwa tizilombo toyambitsa matenda: mphamvu yomatirira kwa tizilombo imawonjezeka kwambiri. Kuonjezera kuchuluka kwa kutirira kwa tizilombo toyambitsa matenda kumathandizira kugwiritsa ntchito pochiza madzi otayira.
- Kusintha kwa gawo lamadzimadzi achitsulo cha organic iron
Kusintha kwa ulusi wa basalt pogwiritsa ntchito organic iron liquid phase deposition kungathandize kulimbitsa mphamvu ya bio-adhesion ya pamwamba pa ulusi ndikuwonjezeranso kugwiritsidwa ntchito kwake pantchito yoyeretsa madzi akumwa. Njira yosinthira iyi ingapangitse kuti ipange utoto wokhazikika wa iron oxide pamwamba pa ulusi kuti uwonjezere kuyamwa kwake ndi kuwonongeka kwa zinthu zoipitsa.
- Kusintha kwa zokutira ndi nano-silica
Tinthu ta nanosilica timafalikira mofanana mu infiltrant kapena dispersion, ndipo tingasinthe utoto wa basalt fiber: pakati pa basalt fiber ndi epoxy resin, tinthu ta nanosilica timagwira ntchito yolumikizira, zomwe zimapangitsa kuti kugwirizana pakati pa ziwirizi kukhale bwino. Pambuyo pa kusintha, kuuma kwa pamwamba pa basalt fiber kumawonjezeka, malo enieni a pamwamba amawonjezeka, ndipo magulu ogwira ntchito okhala ndi mpweya amawonjezeka. Kafukufukuyu adawonetsa kuti pogwiritsa ntchito chonyamulira ulusi wa basalt wosinthidwa ndi nanosilica: kuchuluka kwenikweni kwa filimu ya tizilombo toyambitsa matenda pa gramu imodzi ya ulusi woyikidwa kunawonjezeka ndi 21.39%. Kugwira ntchito bwino kwa kuchotsa zinthu zodetsa kunakula kwambiri.
Mapeto ndi Chiyembekezo
Ntchito ya pamwamba, mphamvu zolumikizirana pakati pa nkhope, ndi magwiridwe antchito a ulusi wa basalt zinasintha kwambiri chifukwa cha njira zosiyanasiyana zosinthira pamwamba.
- Kusintha kwa silane coupling agent ndikoyenera kwambiri pakukonza kumamatira kwa basalt ulusi ndi zinthu za matrix (monga simenti, phula, epoxy resin, ndi zina zotero).
- Kusintha kwa surfactant ndi kusintha kwa organic iron deposition ndi koyenera kwambiri pamunda woteteza chilengedwe, makamaka pogwiritsira ntchito tizilombo toyambitsa matenda pochiza zimbudzi.
- Kusintha kwa nano-silica plating, komwe kuli ndi ubwino wokonzanso mawonekedwe a makina ndi magwiridwe antchito, kuli ndi mwayi wosiyanasiyana m'munda wa Zipangizo Zophatikizana ndi kuteteza chilengedwe.
Kafukufuku wamtsogolo angathandize kwambiri kusintha kwa njira ndi kufufuza momwe njira zosiyanasiyana zosinthira zimagwirira ntchito kuti zikwaniritse zosowa za mapulogalamu osiyanasiyana.
