Ukusuka ku-Smooth kuye ku-"Micro-Pitted": Indlela I-Acid-Base Etching ithuthukisa ngayo ukusebenza kwe-Basalt Fiber

I-Acid-base ifakiwe i-basalt fiberiyimpahla ye-basalt fiber ephathwe ngokukhethekile enomzimba oyingqayizivele futhi Amakhemikhali izakhiwo.

Izinguquko Ze-Surface Morphology

Ukwenyuka kwe-Micro-Roughness

Ubuso bokungalashwa i-basalt fiber bushelelezi uma kuqhathaniswa. Kodwa-ke, ngemuva kokufakwa kwe-acid-base, i-fiber surface ibonisa imigodi emincane eminingi namaqhubu. Lokhu kungenxa yokuthi izixazululo ze-acid-base zisabela ngamakhemikhali nezingxenye zamaminerali endaweni yefayibha, ngokukhetha zincibilikise izinto ezithile.

Isibonelo, ukufakwa kwe-asidi kungase kuncibilikise ngokukhethekile izinhlanganisela zensimbi njenge-calcium ne-magnesium endaweni engaphezulu yefayibha, kuyilapho ukucwiliswa kwesisekelo kungase kubangele izinga elithile lokugqwala kwezinhlanganisela ze-silicon, okuholela endaweni engalingani, emahhadlahhadla. Lokhu kwanda kobukhulu obuncane kungakhulisa indawo yokuxhumana phakathi kwe-fiber kanye nezinto ze-matrix njengama-resin.

Ukushintsha Ububanzi

Ngokuvamile, i-acid-base etching inciphisa kancane ububanzi be i-basalt fiber. Lokhu kungenxa yokuthi enye impahla engaphezulu kwefayibha iyancibilika, okuholela ekwehleni kancane kosayizi wefayibha jikelele. Kodwa-ke, lolu shintsho lobubanzi luvamise ukuba luncane futhi lungalawulwa ngokulawula izici ezifana nesikhathi sokuqopha kanye nokugcwala kwe-asidi noma isisekelo.

Izinguquko Zokwakheka Kwamakhemikhali

Ukususwa Ukungcola

Okwangempela imicu ye-basaltingaqukatha amanye amaminerali angcolile, njengama-iron oxides nama-aluminium oxides. I-Acid-base etching ingasusa noma yehlise okuqukethwe kwalokhu kungcola. Isibonelo, ukufakwa kwe-asidi kungancibilikisa ngempumelelo ukungcola okufana ne-iron oxide, ngaleyo ndlela kuthuthukise ukuhlanzeka kwefayibha. Lokhu kubalulekile ekuthuthukiseni izakhiwo zenyama nezamakhemikhali zefayibha, njengoba ukuba khona kokungcola kungase kuthinte izakhiwo ezifana namandla efayibha kanye Ukumelana Nokugqwala.

Ukulungiswa Kwesilinganiso Sesici

I-Acid-base etching iphinde iguqule isilinganiso sezakhi ku-basalt fiber. Isibonelo, ngesikhathi sokufakwa kwe-asidi, okuqukethwe okuhlobene kwezakhi ze-silicon kungase kukhule ngenxa yokuhlakazeka kwezinye izakhi zensimbi; isimo esiphambene singase senzeke phakathi ne-base etching. Lolu shintsho lwesilinganiso se-elementi luthinta izakhiwo ze-fiber ezifana nokuzinza kwamakhemikhali nokuzinza kwe-thermal.

Izinguquko Zokusebenza Komzimba

Ukushintsha Amandla

I-Acid-base etching inomphumela oyinkimbinkimbi emandleni i-basalt fiber. Ngakolunye uhlangothi, ukwanda kokuqina kwendawo kanye nokususwa kokungcola, ngokwezinga elithile, kungathuthukisa amandla okuhlanganisa ubuso phakathi kwefayibha kanye nokokusebenza kwe-matrix, okuzuzisa ukuthuthukisa amandla ezinto eziyinhlanganisela. Ngakolunye uhlangothi, uma i-etching idlulele, okuholela ekulimaleni okukhulu kwendawo noma ububanzi obuncane kakhulu obuncane, amandla angaphakathi efayibha ngokwawo angase ehle. Ngakho-ke, inqubo yokufaka idinga ukuthuthukiswa ukuze kulinganiswe lezi zici ezimbili zethonya.

Ukusebenza Kwe-Adsorption Okuthuthukisiwe

I-fiber surface ehlanganisiwe inamasayithi asebenza kakhulu, athuthukisa ukusebenza kwawo kwe-adsorption. Isibonelo, lapho ikhangisa i-matrix ye-resin, ingahlangana kangcono nama-molecule e-resin ukuze kwakhe ungqimba oluqinile oluhlangene nobuso. Ngesikhathi esifanayo, kwezinye izinto zokumboza ezisebenzayo noma izithasiselo, i-fiber egxiliwe ingase futhi iwakhangise kangcono, ngaleyo ndlela inikeze ukusebenza okwengeziwe kokuhlanganisiwe.
