Ho bapisa liphello tsa mekhoa e fapaneng ea ho fetola mekhoa ea mechine ea likhoele tsa basalt
1.Phello ea phetoho ea silane coupling agent ka thepa ea mechine
Silane coupling agents (mohlala, KH-550 le KH-570) e etsa lesela le sebetsang holim'a likhoele tsa basalt Lik'hemik'hale tlamahano, e leng ho ntlafatsa tlamahano interfacial pakeng tsa likhoele le substrate, 'me ka nako e tšoanang, e na le phello e itseng ka thepa ea mechine ea likhoele.
KH-550 Fetotse:
Melemo: theha maqhama a lik'hemik'hale holim'a fiber, 'me u ntlafatse ho khomarela pakeng tsa fiber le substrate, ntle le ho senya thepa ea mochine ka boeona.
Tšusumetso: Liphuputso li bonts'a hore ka mor'a phetoho ea KH-550, matla a tsitsipano le modulus ea elasticity ea likhoele tsa basalt ha e le hantle li lula li sa fetohe, empa ka lebaka la ntlafatso ea thepa ea maqhama a sefahleho, thepa e akaretsang ea thepa e kopantsoeng e ntlafatsoa haholo.
KH-570 phetoho:
Melemo: KH-570 e oka holim'a likhoele tsa basalt mme e ntlafatsa ho kenella ha tsona ka mochini le matrix.
Tšusumetso: Le hoja ho tsikitlanya ha holim'a metsi ho ka fokotsa hanyenyane matla a tsitsitseng a likhoele, matla ka kakaretso, ho tiea le ho tšoarella ha motsoako ho ntlafatsoa haholo ka lebaka la mekhoa e ntlafetseng ea ho kopanya sefahleho.
2.Phello ea phetoho ea surfactant ho thepa ea mochine
Li-Cationic surfactants (mohlala, CTAC) li etsa lesela holim'a faeba haholo-holo ka ho ikamahanya le 'mele, 'me sepheo sa tsona se seholo ke ho ntlafatsa hydrophilicity le dispersibility ea likhoele.
Molemo:Phetoho ea surfactant ha e na phello ea khoholeho ea lik'hemik'hale holim'a fiber, ka hona e na le phello e fokolang ho thepa ea mochine ea fiber.
Tšusumetso: Matla a tsitsitseng le modulus ea elastic ea fiber ha e le hantle ha e fetohe ka mor'a phetoho ea CTAC. Phetoho e haholo-holo e ntlafatsa dispersibility le hydrophilicity ea likhoele, e le hore thepa ea matrix e koahele likhoele ka mokhoa o ts'oanang, ka tsela e sa tobang ho ntlafatsa thepa ea mochini oa li-composites.
3.Phello ea phetoho ea ho roala ha nano silica holim'a thepa ea mechine
Ho roala ha Nano-silica ho ntlafatsa bokhabane ba bokaholimo le bokhoni ba ho kopanya sefahleho pakeng tsa likhoele le matrix ka ho etsa lera le ts'oanang la nanoparticles holim'a likhoele tsa basalt.
Molemo: Likaroloana tsa nano-silica li sebetsa e le "borokho" holim'a fiber, ho matlafatsa maqhama pakeng tsa fiber le matrix.
Tšusumetso:Ho roala ha silika nanoparticles ho ka baka tšenyo e nyane ea 'mele holim'a fiber, empa phello ea eona ho matla a khoheli a likhoele e nyane (hangata e ka tlase ho 5%). Ka mor'a ho fetoloa, thepa e akaretsang ea mochine (mohlala, matla a ho tsitsa, matla a flexural) a thepa e kopantsoeng e ka ntlafatsoa haholo, ho fihlela ho 15% -30%.
4.Effect ea manyolo tšepe mokelikeli deposition mohato ka thepa ea mechine
Mokhoa oa ho beha karolo ea mokelikeli oa tšepe ea tlhaho o sebelisoa haholo ho ntlafatsa bokhoni ba ho khomarela bio ea likhoele tsa basalt, 'me ntlafatso ea eona ea thepa ea mochini ha e tobane le ho feta.
Molemo: ho thehoa ha ho roala ho na le phello e nyenyane holim'a thepa ea mechine ea fiber, 'me haholo-holo e ntlafatsa ts'ebetso ea fiber.
Tšusumetso:lera la ho roala le ka eketsa hanyenyane ho tiea ha fiber, empa phello ea matla a ho tsitsa kapa a flexural ha a bohlokoa. Thepa ea mochini ea li-composites tse fetotsoeng e na le moeli, 'me hangata e sebelisoa tšimong ea ts'ireletso ea tikoloho.
5.Phello ea liphetoho tse ling tsa 'mele kapa tsa lik'hemik'hale ho thepa ea mochine
Mekhoa ea 'mele (mohlala, kalafo ea mocheso):
Kalafo ea mocheso e ka fetola sebopeho sa holim'a fiber, empa e ka baka tšenyo ea mocheso ho fiber ka boeona, e leng se fellang ka ho fokotseha ha matla a thata. Kalafo e nepahetseng ea mocheso e thusa ho tlosa lera le litšila holim'a fiber, kahoo ka tsela e sa tobang ho ntlafatsa thepa ea ho kopanya sefahleho pakeng tsa fiber le matrix.
Phetoho ea lik'hemik'hale:
Etching ea lik'hemik'hale (mohlala, kalafo ea asiti) e etsa hore bokaholimo ba fiber bo be thata 'me bo matlafatsa mokhoa oa ho kenella oa sebopeho. Leha ho le joalo, etching e ka 'na ea fokolisa fiber ka boeona, ea fella ka tahlehelo ea thepa e tsitsitseng, e lokelang ho lekanngoa.
