Kuyerekeza zotsatira za njira zosiyanasiyana zosinthira pa mphamvu zamakina a ulusi wa basalt
1. Zotsatira za kusintha kwa silane coupling agent pa makina
Zinthu zolumikizirana ndi silane (monga KH-550 ndi KH-570) zimapanga utoto wochitapo kanthu pamwamba pa ulusi wa basalt kudzera mu Mankhwala Kulumikizana, komwe kumawongolera kulumikizana pakati pa ulusi ndi substrate, ndipo nthawi yomweyo, kumakhudza kwambiri momwe ulusi umagwirira ntchito.
KH-550 Yosinthidwa:
Ubwino: kupanga mgwirizano wa mankhwala pamwamba pa ulusi, ndikuwonjezera kumatirira pakati pa ulusi ndi substrate, popanda kuwononga kwambiri mphamvu zamakina za ulusi wokha.
Zotsatira: Kafukufuku akusonyeza kuti pambuyo pa kusintha kwa KH-550, mphamvu yokoka ndi kusinthasintha kwa ulusi wa basalt sizisintha kwenikweni, koma chifukwa cha kusintha kwa mphamvu zolumikizirana pakati pa nkhope, mphamvu zonse zamakina a zinthu zophatikizika zimakula kwambiri.
Kusintha kwa KH-570:
Ubwino: KH-570 imakoka pamwamba pa ulusi wa basalt ndikuwonjezera kuyika kwawo kwamakina ndi matrix.
Zotsatira: Ngakhale kukhwimitsa pamwamba kungachepetse mphamvu yokoka ya ulusi, mphamvu yonse, kulimba, ndi kulimba kwa chophatikizacho zimawonjezeka kwambiri chifukwa cha mawonekedwe abwino a kulumikizana kwa interfacial.
2. Zotsatira za kusintha kwa surfactant pa katundu wa makina
Ma cationic surfactants (monga CTAC) amapanga utoto pamwamba pa ulusi makamaka kudzera mu kulowetsedwa kwa thupi, ndipo cholinga chawo chachikulu ndikuwonjezera kufalikira kwa ulusi ndi kufalikira kwake.
Ubwino:Kusintha kwa surfactant sikukhudza kwambiri kukokoloka kwa ulusi, kotero sikukhudza kwambiri mphamvu za ulusi.
Zotsatira: Mphamvu yokoka ndi kusinthasintha kwa ulusi sizisintha kwenikweni pambuyo pa kusintha kwa CTAC. Kusinthaku kumathandizira kwambiri kufalikira ndi kusinthasintha kwa ulusi, kotero kuti zinthu za matrix zimakulunga ulusi mofanana, motero zimawongolera mwanjira ina mphamvu zamakina a zophatikizika.
3. Zotsatira za kusintha kwa nano silica ❖ kuyanika pa makina
Kuphimba kwa nano-silica kumathandizira kukhwima kwa pamwamba ndi kuthekera kolumikizana pakati pa ulusi ndi matrix mwa kupanga gawo lofanana la tinthu tating'onoting'ono pamwamba pa ulusi wa basalt.
Ubwino: Tinthu ta nano-silica timagwira ntchito ngati "mlatho" pamwamba pa ulusi, kulimbitsa mgwirizano pakati pa ulusi ndi matrix.
Zotsatira:Kuphimba kwa tinthu tating'onoting'ono ta silica kungayambitse kuwonongeka pang'ono kwa ulusi pamwamba, koma kukhudza kwake mphamvu yokoka ya ulusi kumakhala kochepa (nthawi zambiri kochepera 5%). Pambuyo posintha, mawonekedwe onse a makina (monga mphamvu yokoka, mphamvu yokoka) ya zinthu zophatikizika zimatha kukonzedwa bwino kwambiri, mpaka 15%-30%.
4. Zotsatira za kusintha kwa organic iron liquid phase deposition pa makina
Njira yosungira madzi achitsulo cha organic imagwiritsidwa ntchito makamaka kukulitsa luso la kumatira kwa ulusi wa basalt, ndipo kukulitsa kwake mphamvu zamakanika sikolunjika.
Ubwino: Kupangidwa kwa chophimbacho kumakhudza pang'ono mphamvu za makina a ulusi, ndipo makamaka kumawonjezera magwiridwe antchito a ulusi.
Zotsatira:Chophimbacho chingawonjezere kulimba kwa ulusi pang'ono, koma mphamvu ya kukoka kapena kusinthasintha si yofunikira kwenikweni. Kapangidwe ka makina a zinthu zosinthidwazo ndi kochepa, ndipo nthawi zambiri amagwiritsidwa ntchito poteteza chilengedwe.
5. Zotsatira za kusintha kwina kwa thupi kapena mankhwala pa katundu wa makina
Njira zakuthupi (monga chithandizo cha kutentha):
Kutenthetsa kungasinthe kapangidwe ka pamwamba pa ulusi, koma kungayambitse kuwonongeka kwa kutentha kwa ulusi wokha, zomwe zimapangitsa kuti mphamvu yokoka ichepe. Kutenthetsa koyenera kumathandiza kuchotsa zosayera pamwamba pa ulusi, motero kumawongolera mwanjira ina mphamvu zolumikizirana pakati pa ulusi ndi matrix.
Kusintha kwa mankhwala:
Kuduladula kwa mankhwala (monga mankhwala a asidi) kumawononga pamwamba pa ulusi ndikuwonjezera kuyika kwa makina a cholumikizira. Komabe, kuduladula kumatha kufooketsa ulusi wokha, zomwe zimapangitsa kuti mphamvu zomangirira zitayike, zomwe ziyenera kuyezedwa.
Tebulo Loyerekeza Lonse
| Njira Zosinthira | Kapangidwe ka makina kamakhudza mwachindunji | Kupititsa patsogolo mphamvu zonse za makina a zinthu zopangidwa ndi zinthu zosiyanasiyana | Njira Yaikulu Yogwirira Ntchito |
| Cholumikizira cha Silane (KH-550) | Sanakhudzidwe kwambiri | Kwezani kwambiri | Kulumikizana kwa mankhwala kuti pakhale mgwirizano wolumikizana bwino pakati pa nkhope |
| Wothandizira wolumikizira wa Silane (KH-570) | Kukwecha pamwamba kumabweretsa kufooka pang'ono kwa ulusi | Kwezani kwambiri | Kuyika bwino makina |
| Chotsukira cha CTAC | Sanakhudzidwe kwambiri | Kutsatsa kosalunjika | Kufalikira bwino ndi hydrophilicity |
| Nano Silicon Dioxide wokutira | Kufooka pang'ono kwa mphamvu ya ulusi (osapitirira 5%) | Kwezani kwambiri (15% -30%) | Zimawonjezera kuuma ndi kuyanjana kwa nkhope |
| Kusintha kwa organic iron deposition | Sanakhudzidwe kwambiri | Kutsatsa kochepa | Kuphatikizika kwa bio komwe kwalimbikitsidwa |
| mankhwala otentha (monga chitsulo) | Zingayambitse kuwonongeka kwa kutentha komwe kumabweretsa kutayika kwa mphamvu ya ulusi | Kutsatsa kosalunjika | Kuchotsa malo odetsedwa pamwamba ndi kukonza malo olumikizirana pakati pa nkhope |
| Kusintha kwa mankhwala opangidwa ndi mankhwala | Kukonza ulusi kumawonjezera mgwirizano pakati pa nkhope koma kungafooketse ulusi | Kutsatsa kochepa | Kukonza pamwamba kuti pakhale makina owonjezera |
Mapeto
- Njira zolumikizirana za silane ndi nano-silica pakadali pano ndi njira zosinthira zomwe sizikhudza kwambiri mphamvu zamakina za ulusi wa basalt, pomwe nthawi yomweyo zimawongolera kwambiri mphamvu zonse zamakina a zophatikizika.
- Kusintha kwa surfactant sikukhudza mwachindunji mphamvu za ulusi, ndipo ndikoyenera pazochitika zomwe zimafunika kukonza kufalikira kapena kusinthasintha kwa ulusi.
- Kupaka mankhwala ndi kutentha kuyenera kugwiritsidwa ntchito mosamala, chifukwa ngakhale kuti kumatha kukonza bwino maulumikizidwe a pakati pa nkhope, kungayambitse kuchepa kwa maulumikizidwe a ulusi.
- Kusankha njira yosinthira kuyenera kutengera zofunikira zogwiritsira ntchito poyesa momwe ulusiwo umagwirira ntchito komanso momwe zinthu zophatikizika zimagwirira ntchito kuti ziwongolere zotsatira zake.
