Ukuqhathaniswa kwemiphumela yezindlela ezahlukene zokuguqula ezimpahleni zemishini yezintambo ze-basalt
1. Umphumela wokuguqulwa kwe-ejenti yokuhlanganisa i-silane ezimpahleni zemishini
Ama-ejenti okuhlanganisa i-silane (isb. i-KH-550 kanye ne-KH-570) akha ungqimba olusabelayo phezu kwezintambo ze-basalt ngokusebenzisa Amakhemikhali ukubopha, okuthuthukisa ukubopha okuphakathi kwezintambo kanye ne-substrate, futhi ngesikhathi esifanayo, kunomthelela othile ezimpahleni zemishini zezintambo.
I-KH-550 Ishintshiwe:
Izinzuzo: yakha isibopho samakhemikhali ebusweni befayibha, futhi ithuthukise ukunamathelana phakathi kwefayibha kanye ne-substrate, ngaphandle kokulimaza kakhulu izakhiwo zemishini zefayibha uqobo.
Umthelela: Izifundo zibonisa ukuthi ngemva kokuguqulwa kwe-KH-550, amandla okudonsa kanye ne-modulus yokuqina kwezintambo ze-basalt ngokuyisisekelo akushintshanga, kodwa ngenxa yokuthuthukiswa kwezakhiwo zokubopha phakathi kwe-interfacial, izakhiwo zomshini eziphelele zezinto ezihlanganisiwe zithuthukiswa kakhulu.
Ukuguqulwa kwe-KH-570:
Izinzuzo: I-KH-570 iqinisa ubuso bezintambo ze-basalt futhi ithuthukise ukufakwa kwazo ngomshini nge-matrix.
Umthelela: Nakuba ukugoqa ubuso kunganciphisa kancane amandla okuthamba kwemicu, amandla aphelele, ukuqina, kanye nokuqina kwenhlanganisela kuthuthuka kakhulu ngenxa yezakhiwo ezithuthukisiwe zokubopha phakathi kwe-interfacial.
2. Umphumela wokuguqulwa kwe-surfactant ezimpahleni zemishini
Ama-surfactant e-cationic (isb. i-CTAC) akha ungqimba ebusweni be-fiber ikakhulukazi ngokumuncwa ngokomzimba, futhi inhloso yawo eyinhloko ukuthuthukisa ukunamathela kwamanzi kanye nokuhlakazeka kwe-fiber.
Inzuzo:Ukuguqulwa kwe-surfactant cishe akunawo umphumela wokuguguleka kwamakhemikhali ebusweni be-fiber, ngakho-ke kunomthelela omncane ezimpahleni ze-fiber.
Umthelela: Amandla okuthamba kanye ne-modulus yokunwebeka kwefayibha akushintshile ngemuva kokuguqulwa kwe-CTAC. Ukuguqulwa ikakhulukazi kuthuthukisa ukuhlakazeka kanye nokunamathela kwamanzi kwefayibha, ukuze izinto ze-matrix zigoqe imicu ngokulinganayo, ngaleyo ndlela zithuthukise ngokungaqondile izakhiwo zemishini yezinhlanganisela.
3. Umphumela wokuguqulwa kokumbozwa kwe-nano silica ezimpahleni zemishini
Ukugqoka i-nano-silica kuthuthukisa ubulukhuni bomphezulu kanye nekhono lokubopha phakathi kwemicu kanye ne-matrix ngokwakha ungqimba olufanayo lwezinhlayiya ezincane ebusweni bemicu ye-basalt.
Inzuzo: Izinhlayiya ze-nano-silica zisebenza “njengebhuloho” ebusweni befayibha, ziqinisa ukubopha phakathi kwefayibha kanye ne-matrix.
Umthelela:Ukumbozwa kwezinhlayiya ezincane ze-silica kungabangela umonakalo omncane ongokwenyama ebusweni be-fiber, kodwa umthelela wayo emandleni okudonsa ama-fiber mncane (ngokuvamile ngaphansi kuka-5%). Ngemva kokuguqulwa, izakhiwo ezijwayelekile zemishini (isb. amandla okudonsa, amandla okuguquguquka) kwezinto ezihlanganisiwe zingathuthukiswa kakhulu, kuze kufike ku-15%-30%.
4. Umphumela wokuguqulwa kwesigaba sokufakwa kwe-iron liquid ye-organic kuzakhiwo zemishini
Indlela yokufaka uketshezi lwensimbi oluyi-organic isetshenziswa kakhulu ukuthuthukisa ikhono lokunamathela kwe-bio lemicu ye-basalt, futhi ukuthuthukiswa kwayo kwezakhiwo zemishini akuqondile kakhulu.
Inzuzo: Ukwakheka kwengubo kunomthelela omncane ezimpahleni zemishini ze-fiber, futhi ikakhulukazi kuthuthukisa ukusebenza kwe-fiber.
Umthelela:ungqimba lokumboza lungakhulisa kancane ukuqina kwefayibha, kodwa umthelela emandleni okuthambekela noma okugobekayo awubalulekile. Izakhiwo zemishini zezinhlanganisela eziguquliwe zilinganiselwe, futhi zivame ukusetshenziswa kakhulu emkhakheni wokuvikela imvelo.
5. Umphumela wezinye izinguquko zomzimba noma zamakhemikhali ezimpahleni zemishini
Izindlela zomzimba (isib. ukwelashwa ngokushisa):
Ukwelashwa ngokushisa kungashintsha isakhiwo sobuso befayibha, kodwa kungabangela umonakalo wokushisa kufayibha uqobo, okuholela ekunciphiseni kwamandla okudonsa. Ukwelashwa ngokushisa okufanele kusiza ukususa ungqimba lokungcola ebusweni befayibha, ngaleyo ndlela kuthuthukise ngokungaqondile izakhiwo zokubopha phakathi kwefayibha kanye ne-matrix.
Ukuguqulwa kokuqopha kwamakhemikhali:
Ukuqopha ngamakhemikhali (isb., ukwelashwa nge-asidi) kuqinisa ubuso befayibha futhi kuthuthukise ukushumeka komshini kwe-interface. Kodwa-ke, ukuqopha kungenza ifayibha ibe buthaka, okuholela ekulahlekelweni kwezakhiwo zokuthamba, okudingeka zilinganiswe.

Isiphetho
- I-ejenti yokuhlanganisa i-silane kanye ne-nano-silica coating okwamanje yizindlela zokuguqula ezinomthelela omncane kakhulu ezimpahleni zemishini ze-basalt fibers, kuyilapho ngesikhathi esifanayo zithuthukisa kakhulu izakhiwo zemishini ze-composites.
- Ukuguqulwa kwe-surfactant cishe akunawo umthelela oqondile ezimpahleni zemishini zemicu, futhi kufanelekile ezimweni ezidinga ukuthuthukisa ukusabalala noma ukuguquguquka kwemicu.
- Ukwelashwa ngokushisa nokushisa ngamakhemikhali kufanele kusetshenziswe ngokuqapha, ngoba nakuba kungathuthukisa izakhiwo zokubopha phakathi kwe-interfacial, kungaholela ekunciphiseni izakhiwo zemishini zemicu.
- Ukukhetha indlela yokuguqula kufanele kusekelwe ezidingweni zohlelo lokusebenza ukuze kulinganiswe ukusebenza kwefayibha ngokwayo kanye nokusebenza okuphelele kwezinto ezihlanganisiwe ukuze kuthuthukiswe umphumela.
