Kwatanta tasirin hanyoyin gyare-gyare daban-daban akan kayan aikin injiniya na filayen basalt
1.Effect na silane hadawa wakili gyara a kan inji Properties
Silane hada guda biyu jamiái (misali KH-550 da KH-570) samar da wani reactive shafi a saman basalt zaruruwa ta hanyar. Chemical bonding, wanda inganta interfacial bond tsakanin zaruruwa da substrate, kuma a lokaci guda, yana da wani tasiri a kan inji Properties na zaruruwa.
KH-550 Gyara:
Amfani: samar da haɗin sinadarai a saman fiber ɗin, da kuma inganta mannewa tsakanin fiber da substrate, ba tare da yin lahani sosai ga kayan aikin fiber da kansa ba.
Tasiri: Nazarin ya nuna cewa bayan KH-550 gyara, da tensile ƙarfi da kuma modulus na elasticity na basalt zaruruwa m zama ba canzawa, amma saboda inganta interfacial bonding kaddarorin, gaba daya inji Properties na hadaddun abu suna da muhimmanci inganta.
KH-570 gyara:
Amfani: KH-570 yana jujjuya saman filayen basalt kuma yana haɓaka haɓaka injin su tare da matrix.
Tasiri: Duk da yake jujjuyawar saman na iya ɗan rage ƙarfin ƙwanƙolin zaruruwan, ƙarfin gabaɗaya, tauri, da dorewa na abin da aka haɗa yana da kyau sosai saboda ingantattun kaddarorin haɗin fuska.
2.Effect na surfactant gyara a kan inji Properties
Cationic surfactants (misali CTAC) samar da wani shafi a kan fiber surface yafi ta jiki adsorption, kuma su babban manufar shi ne don inganta hydrophilicity da dispersibility na zaruruwa.
Amfani:A surfactant gyare-gyare ba shi da kusan wani sinadaran yashwa sakamako a kan fiber surface, don haka yana da m tasiri a kan inji Properties na fiber.
Tasiri: Ƙarfin ƙarfi da na roba na fiber ba su canzawa a zahiri bayan gyaran CTAC. A gyara yafi inganta dispersibility da hydrophilicity na zaruruwa, sabõda haka, da matrix abu uniformly wraps da zaruruwa, ta haka a kaikaice inganta inji Properties na composites.
3.Effect na Nano silica shafi gyara a kan inji Properties
Rufin Nano-silica yana haɓaka haɓakar yanayin ƙasa da ƙarfin haɗin kai tsakanin zaruruwa da matrix ta hanyar samar da nau'in nau'in nanoparticles a saman filayen basalt.
Amfani: Kwayoyin nano-silica suna aiki a matsayin "gada" akan filayen fiber, ƙarfafa haɗin kai tsakanin fiber da matrix.
Tasiri:Rubutun silica nanoparticles na iya haifar da ɗan lahani na zahiri ga saman fiber, amma tasirinsa akan ƙarfin ƙwanƙwasa zaruruwa kaɗan ne (yawanci ƙasa da 5%). Bayan gyare-gyare, gabaɗayan kayan aikin injiniya (misali ƙarfin ƙarfi, ƙarfin sassauƙa) na kayan haɗin gwiwar za'a iya inganta su sosai, har zuwa 15% -30%.
4.Effect na Organic baƙin ƙarfe ruwa lokaci shaida gyare-gyare a kan inji Properties
Hanyar shigar da ruwa na ƙarfe na ƙarfe galibi ana amfani dashi don haɓaka ƙarfin bio-mannewa na filayen basalt, kuma haɓaka kayan aikin injina ya fi kaikaice.
Amfani: Ƙirƙirar murfin yana da ƙananan tasiri akan kayan aikin injiniya na fiber, kuma yafi haɓaka aikin fiber.
Tasiri:Layer Layer na iya ɗan ƙara ƙara ƙarfin fiber, amma tasiri akan ƙarfin ƙarfi ko sassauci ba shi da mahimmanci. Kayan aikin injiniya na abubuwan da aka gyara sun iyakance, kuma ana amfani da su sau da yawa a cikin filin kare muhalli.
5.Tasirin wasu gyare-gyare na jiki ko sinadarai akan kayan aikin injiniya
Hanyoyin jiki (misali maganin zafi):
Maganin zafi na iya canza tsarin saman fiber ɗin, amma yana iya haifar da lalacewar zafin jiki ga fiber ɗin kanta, yana haifar da raguwar ƙarfin ƙarfi. Maganin zafi da ya dace yana taimakawa wajen cire ƙazanta mai ƙazanta a kan filaye na fiber, don haka a kaikaice inganta abubuwan haɗin kai tsakanin fiber da matrix.
Gyaran sinadarai:
Chemical etching (misali, acid magani) roughens da fiber surface da kuma kara habaka inji sakawa na dubawa. Duk da haka, etching na iya raunana fiber ɗin kanta, yana haifar da asarar kaddarorin ƙarfi, wanda ke buƙatar auna.
