Ukuqhathaniswa kwemiphumela yezindlela ezihlukene zokuguqulwa kwezakhiwo zemishini ye-basalt fibers
1.Umthelela wokuguqulwa kwe-ejenti yokuhlanganisa i-silane kuzakhiwo zemishini
I-Silane coupling agents (isb. i-KH-550 ne-KH-570) yenza ukunamathela okusebenzayo ebusweni bemicu ye-basalt ngokusebenzisa Amakhemikhali ukubopha, okuthuthukisa ukuhlangana okuhlangene phakathi kwezintambo kanye ne-substrate, futhi ngesikhathi esifanayo, kunomphumela othile ezakhini zemishini yezintambo.
I-KH-550 elungisiwe:
Izinzuzo: yakha isibopho samakhemikhali endaweni ye-fiber, futhi uthuthukise ukunamathela phakathi kwe-fiber ne-substrate, ngaphandle kokulimaza kakhulu izakhiwo zemishini ye-fiber ngokwayo.
Umthelela: Ucwaningo lubonisa ukuthi ngemva kokuguqulwa kwe-KH-550, amandla aqinile kanye ne-modulus ye-elasticity ye-basalt fibers ngokuyisisekelo ahlala engashintshi, kodwa ngenxa yokuthuthukiswa kwezakhiwo zokuhlanganisa ubuso obuhlangene, izici eziphelele zemishini yezinto ezihlanganisiwe zithuthukiswa kakhulu.
Ukulungiswa kwe-KH-570:
Izinzuzo: I-KH-570 yenza rough ingaphezulu lemicu ye-basalt futhi ithuthukise ukushumeka kwayo ngomshini nge-matrix.
Umthelela: Nakuba ukuqina kwendawo kungase kwehlise kancane amandla aqinile emicu, amandla awo wonke, ukuqina, nokuqina kwenhlanganisela kuba ngcono kakhulu ngenxa yezakhiwo ezithuthukisiwe zokuhlanganisa ubuso.
2.Umphumela wokuguqulwa kwe-surfactant kuzakhiwo zemishini
Ama-Cationic surfactants (isb. i-CTAC) akha i-coating endaweni yefayibha ikakhulukazi ngokusebenzisa i-adsorption ebonakalayo, futhi inhloso yawo enkulu ukuthuthukisa i-hydrophilicity kanye nokuhlakazeka kwemicu.
Inzuzo:Ukuguqulwa kwe-surfactant cishe akunawo umthelela wokuguguleka kwamakhemikhali endaweni yefayibha, ngakho-ke kunomthelela omncane kuzakhiwo zemishini zefiber.
Umthelela: Amandla aqinile kanye nemodulus enwebekayo yefiber empeleni akushintshile ngemva kokuguqulwa kwe-CTAC. Ukuguqulwa ngokuyinhloko kuthuthukisa i-dispersibility kanye ne-hydrophilicity ye-fibers, ukuze impahla ye-matrix igoqe ngokulinganayo imicu, ngaleyo ndlela ithuthukise ngokungaqondile izakhiwo zemishini yezinhlanganisela.
I-3.Umphumela we-nano silica coating ukuguqulwa kuzakhiwo zemishini
I-Nano-silica coating ithuthukisa ubulukhuni obungaphezulu kanye nekhono lokuhlangana phakathi kobuso phakathi kwemicu kanye ne-matrix ngokwenza ungqimba olufanayo lwama-nanoparticles ebusweni bemicu ye-basalt.
Inzuzo: Izinhlayiya ze-nano-silica zisebenza "njengebhuloho" endaweni ye-fiber, eqinisa ukuhlangana phakathi kwe-fiber kanye ne-matrix.
Umthelela:Ukumbozwa kwama-silica nanoparticles kungase kubangele umonakalo omncane ongokomzimba endaweni yefayibha, kodwa umthelela wawo emandleni aqinile emicu mincane (imvamisa ingaphansi kuka-5%). Ngemva kokuguqulwa, izakhi zomshini jikelele (isb. amandla aqinile, amandla okuguquguquka) wezinto eziyinhlanganisela zingathuthukiswa kakhulu, zifike ku-15% -30%.
4.Umthelela we-organic iron liquid isigaba sokuguqulwa kwezakhi zemishini
Indlela yokubekwa kwesigaba se-iron liquid ye-organic isetshenziswa kakhulu ukuthuthukisa ikhono lokunamathela kwe-bio-adhesion lemicu ye-basalt, futhi ukuthuthukiswa kwayo kwezakhiwo zemishini akuqondile kakhulu.
Inzuzo: ukwakheka kwe-coating kunethonya elincane ezindaweni zemishini ye-fiber, futhi ikakhulukazi kuthuthukisa ukusebenza kwe-fiber.
Umthelela:ungqimba olunamathelayo lungase lwandise kancane ukuqina kwefayibha, kodwa umthelela emandleni aqinile noma aguquguqukayo awubalulekile. Izakhiwo zemishini yezinhlanganisela eziguquliwe zilinganiselwe, futhi zivame ukusetshenziswa emkhakheni wokuvikela imvelo.
5.Umthelela wezinye izinguquko ezibonakalayo noma zamakhemikhali ezimpahleni zemishini
Izindlela ezingokomzimba (isb ukwelapha ukushisa):
Ukwelashwa kokushisa kungashintsha isakhiwo esingaphezulu se-fiber, kodwa kungase kubangele umonakalo oshisayo ku-fiber ngokwayo, okuholela ekwehleni kwamandla aqinile. Ukwelashwa okufanelekile kokushisa kusiza ukususa isendlalelo sokungcola endaweni yefayibha, ngaleyo ndlela kuthuthukiswe ngokungaqondile izici zokuhlangana phakathi kobuso phakathi kwefayibha kanye ne-matrix.
Ukulungiswa kwe-Chemical etching:
Ukufakwa kwamakhemikhali (isb., ukwelashwa kwe-asidi) kwenza indawo yefayibha ibe lukhuni futhi ithuthukise ukushumeka kokusebenza kwesixhumi esibonakalayo. Kodwa-ke, i-etching ingase ibe buthakathaka i-fiber ngokwayo, okuholela ekulahlekelweni kwezakhiwo eziqinile, ezidinga ukukalwa.
