Ukugqwala kwekhonkrithi kungenye yezimbangela eziyinhloko zokonakala kokuqina kwekhonkrithi, futhi izinkinga zokugqwala kwekhonkrithi zibangela ukulahlekelwa okukhulu kwezomnotho minyaka yonke. Ukuze kuncishiswe ukulahlekelwa kwezomnotho okubangelwa ukugqwala kwekhonkrithi, kubaluleke kakhulu ukutadisha ukumelana nokugqwala kwekhonkrithi ye-basalt fiber.

Ngezinzuzo zabo zokusebenza eziphelele, imicu ye-basalt zisetshenziswa kabanzi ezimbonini ezahlukahlukene, okuhlanganisa izindiza, ezokuvikela, ezokuthutha, amandla amasha, ezokwakha, ubunjiniyela basolwandle, kanye namakhemikhali kaphethiloli. Zisebenza njengenye indlela ethuthukisiwe esikhundleni sezinto zendabuko.

I-Basalt fiber iyi-filament filament eqhubekayo eyenziwe ngedwala le-basalt yemvelo. Idwala liyancibilika ku-1450°C-1500°C bese lidonswa nge-platinum-rhodium alloy bushing ngesivinini esikhulu. I-basalt fiber emsulwa ngokuvamile insundu. Luhlobo olusha lwe-inorganic, enobungani nemvelo, esebenza kahle kakhulu eyakhiwe ngama-oxide afana ne-silicon dioxide, i-aluminium oxide, i-calcium oxide, i-magnesium oxide, i-iron oxide, kanye ne-titanium dioxide. I-basalt continuous fiber ayigcini nje ngokuba namandla aphezulu kodwa futhi inezakhiwo ezinhle kakhulu njengokushisa kukagesi, ukumelana nokugqwala, kanye nokumelana nokushisa okuphezulu. Ngaphezu kwalokho, inqubo yayo yokukhiqiza ikhiqiza imfucuza encane kanye nokungcola kwemvelo, futhi umkhiqizo olahliwe ungonakala ngokwemvelo ngaphandle kokulimala, okwenza kube yinto eluhlaza ngempela futhi enobungani nemvelo. I-China ibhale i-basalt fiber njengenye yezintambo ezine ezibalulekile zokuthuthukiswa (kanye ne-carbon fiber, i-aramid, kanye ne-polyethylene enesisindo sama-molecule esiphezulu) futhi ifinyelele ekukhiqizweni kwezimboni. I-basalt fiber eqhubekayo manje isetshenziswa kabanzi ezintweni eziqiniswe yi-fiber, izinto zokungqubuzana, ukwakha imikhumbi, imboni yezimoto, kanye nezicelo zokushisa okuphezulu kanye nokuvikela.

Ezakhiweni ezintsha zezindlu zokuhlala, izinhlanganisela ze-basalt fiber-reinforced polymer (BFRP) ziyavela njengezinto zokwakha ezithembisayo kakhulu ngenxa yezakhiwo zazo ezinhle kakhulu, okuhlanganisa amandla aphezulu, ubunjalo obulula, ukumelana nokugqwala, kanye nokusebenza okuphezulu kokuzamazama komhlaba.

Nakuba izindleko zokuqala ze-basalt fiber-reinforced polymer (BFRP) composites ziphakeme, izinzuzo zazo zezomnotho zesikhathi eside ekwakhiweni kwezindlu zibalulekile.

Ikhonkrithi ye-basalt fibre eqoshiwe kufanele yakhiwe ngaphansi kwamazinga okushisa asukela ku-5°C kuya ku-25°C. Kokubili amazinga okushisa aphezulu kakhulu noma aphansi kakhulu angaholela ekuxubeni okungalingani.

Ikhonkrithi eqiniswe ngefayibha ye-basalt eqoshiwe ihilela ukufaka inani elithile lemicu ye-basalt eqoshiwe eqhubekayo noma engaqhubeki kukhonkrithi kusetshenziswa indlela efanele. Le ndlela igcina izinzuzo zamandla okucindezela ekhonkrithi ngenkathi ithuthukisa kakhulu ukuqina kwayo kanye namandla okunamathela, ngaleyo ndlela iqinisa futhi iqinise ikhonkrithi ngempumelelo futhi yandise impilo yenkonzo yezakhiwo zobunjiniyela.

Ikhonkrithi iyinto yokwakha esetshenziswa kakhulu. Inikeza izinzuzo eziningi, okuhlanganisa ukutholakala kwayo kabanzi, inqubo yokukhiqiza elula, izindleko eziphansi, kanye nokulula kokusetshenziswa. Isetshenziswa kabanzi emikhakheni ehlukahlukene njengezakhiwo, imigwaqo, amabhuloho, imigudu, kanye nobunjiniyela be-hydraulic. Njengoba inani elikhulu lamaphrojekthi obunjiniyela liye lathuthuka, izidingo zokusebenza kwekhonkrithi nazo ziye zanda kancane kancane. Ngenxa yalokho, ukushiyeka kwekhonkrithi yendabuko, njengokuqina okunganele kokucindezelwa, ukumelana nokuqhekeka okungekuhle, kanye nokungazinzi komthamo, kuye kwabonakala. Ngakho-ke, ukuthuthukisa ukusebenza kwekhonkrithi kuye kwaba yinye yezinkomba ezibalulekile zocwaningo kubunjiniyela bezokwakha.

Emkhakheni wobunjiniyela bezakhiwo, izakhiwo zekhonkrithi ziyingxenye ebaluleke kakhulu. Kodwa-ke, ngokuthuthuka kwemboni yokwakha, inkinga yemfucuza yokwakha iya ngokuya igqama, kanti ikhonkrithi elahliwe ibalwa kakhulu. Ukuze kufezwe umgomo wekhabhoni ephansi embonini yokwakha, ukusetshenziswa kwekhonkrithi ephinde yasetshenziswa kuye kwadonsela ukunaka kancane kancane. Noma kunjalo, ikhonkrithi ephinde yasetshenziswa inamaphutha athile ekusetshenzisweni okungokoqobo, njengokungabi namandla anele kanye nokuqina okungekuhle.
