Kuyerekeza zotsatira za njira zosiyanasiyana zosinthira pamakina a ulusi wa basalt
1.Effect ya silane coupling agent kusinthidwa pa makina katundu
Silane coupling agents (monga KH-550 ndi KH-570) amapanga zokutira pamwamba pa ulusi wa basalt. Chemical kugwirizana, amene bwino interfacial kugwirizana pakati ulusi ndi gawo lapansi, ndipo nthawi yomweyo, ali ndi zotsatira zina pa makina zimatha ulusi.
KH-550 Zosinthidwa:
Ubwino: kupanga chomangira chamankhwala pamtunda, ndikuwongolera kumamatira pakati pa CHIKWANGWANI ndi gawo lapansi, popanda kuwononga kwambiri makina a ulusi womwewo.
Zotsatira: Kafukufuku akuwonetsa kuti pambuyo pa kusinthidwa kwa KH-550, mphamvu yamakomedwe ndi modulus ya elasticity ya ulusi wa basalt imakhalabe yosasinthika, koma chifukwa cha kusintha kwa mawonekedwe omangirira, mphamvu zonse zamakina azinthu zophatikizika zimasintha kwambiri.
Zithunzi za KH-570
Ubwino: KH-570 imalimbitsa pamwamba pa ulusi wa basalt ndikuwonjezera kuyika kwawo ndi matrix.
Zotsatira: Ngakhale kuwundana kwapamtunda kumatha kuchepetsa kulimba kwa ulusi, mphamvu zonse, kulimba, ndi kulimba kwa gululi zimapita patsogolo kwambiri chifukwa cha kuwongolera kwamalumikizano amitundu.
2.Effect ya surfactant kusinthidwa pa makina katundu
Ma cationic surfactants (monga CTAC) amapanga zokutira pamwamba pa CHIKWANGWANI makamaka kudzera m'mawonekedwe akuthupi, ndipo cholinga chawo chachikulu ndikuwongolera hydrophilicity ndi dispersibility ya ulusi.
Ubwino:The surfactant kusinthidwa ali pafupifupi palibe kukokoloka kwa mankhwala zotsatira pa CHIKWANGWANI pamwamba, choncho alibe mphamvu pa makina katundu CHIKWANGWANI.
Zotsatira: Mphamvu zamakokedwe komanso zotanuka modulus za ulusi sizisintha pambuyo pa kusinthidwa kwa CTAC. The kusinthidwa makamaka bwino dispersibility ndi hydrophilicity ulusi, kuti masanjidwewo zakuthupi uniformly wraps ulusi, motero kuwongolera mawotchi katundu wa nsanganizo.
3.Zotsatira za nano silica zokutira kusinthidwa pa makina katundu
Nano-silika ❖ kuyanika bwino pamwamba roughness ndi interfacial kugwirizana luso pakati ulusi ndi masanjidwewo mwa kupanga yunifolomu wosanjikiza wa nanoparticles pamwamba pa basalt ulusi.
Ubwino: Ma nano-silica particles amakhala ngati "mlatho" pamtunda wa fiber, kulimbitsa mgwirizano pakati pa fiber ndi matrix.
Zotsatira:Kupaka kwa silika nanoparticles kungayambitse kuwonongeka pang'ono kwa fiber pamwamba, koma zotsatira zake pa mphamvu yolimba ya ulusi ndizochepa (nthawi zambiri zosakwana 5%). Pambuyo kusinthidwa, mphamvu zonse zamakina (monga mphamvu zamakokedwe, mphamvu zosinthika) zazinthu zophatikizika zimatha kusintha kwambiri, mpaka 15% -30%.
4.Effect of organic iron liquid fluid gawo kusinthidwa pa makina katundu
Organic chitsulo madzi gawo mafunsidwe njira makamaka ntchito kumapangitsanso bio-adhesion luso basalt ulusi, ndi kupititsa patsogolo makina katundu ndi mosalunjika.
Ubwino: mapangidwe ❖ kuyanika ali ndi zotsatira yaing'ono pa makina zimatha CHIKWANGWANI, ndipo makamaka timapitiriza ntchito CHIKWANGWANI.
Zotsatira:wosanjikiza wokutira akhoza kuonjezera pang'ono kulimba kwa ulusi, koma kukhudzika kwamphamvu kapena kusinthasintha sikuli kofunikira. Zomwe zimapangidwira zamagulu osinthidwa ndizochepa, ndipo zimagwiritsidwa ntchito nthawi zambiri pachitetezo cha chilengedwe.
5.Zotsatira za kusintha kwina kwa thupi kapena mankhwala pazinthu zamakina
Njira zolimbitsa thupi (monga chithandizo cha kutentha):
Kuchiza kutentha kumatha kusintha mawonekedwe a ulusi, koma kungayambitse kuwonongeka kwa ulusi womwewo, zomwe zimapangitsa kuchepa kwamphamvu kwamphamvu. Kuchiza koyenera kwa kutentha kumathandiza kuchotsa zosanjikiza zonyansa pamwamba pa ulusi, motero kumapangitsa kuti pakhale mgwirizano pakati pa fiber ndi matrix.
Kusintha kwa Chemical etching:
Chemical etching (mwachitsanzo, asidi mankhwala) roughens CHIKWANGWANI pamwamba ndi timapitiriza makina embedding wa mawonekedwe. Komabe, etching imatha kufooketsa ulusi womwewo, zomwe zimapangitsa kuti mphamvu zake ziwonongeke, zomwe zimafunikira kuyeza.

| Kusintha kwa Chemical etching | Kukantha kumawonjezera kugwirizana kwapakati koma kumatha kufooketsa ulusi | Kukwezedwa kochepa | Pamwamba pa roughening kuti kumangika makina kuika |
Mapeto
- Silane coupling agent ndi nano-silica ❖ kuyanika ndi njira zosinthira zomwe zimakhala ndi zotsatira zochepa pamakina a ulusi wa basalt, pomwe nthawi yomweyo zimathandizira kwambiri mawotchi amitundu yonse.
- Kusinthidwa kwa surfactant kulibe mphamvu yachindunji pamakina a ulusi, ndipo ndikofunikira pazochitika zomwe zimafunikira kupititsa patsogolo kubalalitsidwa kapena hydrophilicity ya ulusi.
- Mankhwala etching ndi kutentha mankhwala ayenera kugwiritsidwa ntchito mosamala, chifukwa ngakhale angathe kusintha interfacial chomangira katundu, zikhoza kuchititsa kuchepa mawotchi zimatha ulusi.
- Kusankhidwa kwa njira yosinthira kuyenera kutengera zofunikira zomwe zimagwiritsidwa ntchito poyesa kulemera kwa fiber palokha komanso magwiridwe antchito onse azinthu zophatikizika kuti zitheke.
