I-BFRP Development Dilemma

1 Ubunzima bokulungiselela

Izinga le-BF lingenye yezinto ezibalulekile ezithinta ikhwalithi ye I-BFRP. Kodwa-ke, ucwaningo lwamanje nge-BFRP lugxile kakhulu emehlukweni wokuthuthukisa i-BF uma kuqhathaniswa namanye amafayibha ezimpahleni ezibonakalayo, kanye nokunqunywa kwezakhiwo ezihlukahlukene ze-BFRP ngaphansi kwezinto ezihlukene. Kukhona ukushoda kocwaningo mayelana I-Basalt izingxenye, ukusatshalaliswa kwezinsiza, inqubo yokukhiqiza ye-BF, izakhiwo zomzimba nezomshini, kanye nezakhiwo zomzimba nezomshini ze-BFRP ezisekelwe ezintweni ezingavuthiwe ezivela ezifundeni ezahlukene. Ngenxa yomehluko omkhulu ezingxenyeni ze-basalt ezifundeni ezihlukene, kuzoholela ekuhlukeni okukhulu kwekhwalithi yamaqoqo ahlukene e-BF, njengasenqubo yokukhiqiza ngaphandle kokuthuthukiswa okuqhubekayo kokuhlukaniswa kwe-basalt, kusetshenziswa izimo zenqubo efanayo, kuzoholela ku-basalt engakwazi ukuncibilika ngokugcwele, evimbela ukukhiqizwa kwe-BF ephezulu yokusebenza, okuzothinta ukukhiqizwa kwe-high-performance.I-BFRP. Njengamanje, ngenxa yokushiyeka kwenqubo yokulungiselela i-BF, i-ejenti yokwenza ifilimu esetshenziswa ekukhiqizeni i-BF isetshenziswa kakhulu ekukhiqizeni ama-agent okwenza ifilimu asetshenziswa ekukhiqizeni ezinye izintambo; ukuncibilika kwezinga lokushisa eliphezulu akushintshiwe ngokuphelele, okuholela ekuqhekekeni okukhulu kwemicu; futhi ukukhiqizwa kwasekhaya kwamafekthri e-BF ngokuvamile asetshenziswa ekukhiqizeni isithando somlilo esincane se-Crucible Furnace ukuze kuzuzwe ukukhiqizwa kwezimboni ezinkulu zesitshalo akuvimbeli ukuthuthukiswa kwezimboni ezinkulu zokukhiqizwa kwe-BF esebenza kahle, ukunciphisa ukukhishwa kwe-BF esebenza kahle kakhulu. Ngenxa yokukhiqizwa kwenqubo ye-BF, ukuguga nokuklebhuka kwepuleti lokuvuza, kanye nesidingo sokuvuselela njalo, amapuleti amancane avuzayo ajwayelekile impilo yesevisi yezinyanga eziyi-9 kuphela, namapuleti amakhulu okuvuza cishe izinyanga eziyi-11. Ipuleti lokuvuza ngokuvamile lenziwe nge-platinum alloy, futhi izindleko ziphezulu, okuholela ezindleko eziphezulu zokukhiqiza ze-BF, okuvimbela ukuthuthukiswa kwe-BFRP emgwaqeni wezindleko eziphansi. Inqubo eyinhlanganisela ye-BF nezinye izinto futhi ingenye yezinto ezibalulekile ezithinta ikhwalithi ye-BFRP. Ngohlelo lwe I-BFRP okulungiselelwe ngenqubo yokuxuba okuqondile, isikhombikubona esibushelelezi se-BF kanye nezici ze-BF okungelula ukusabela kuzo nezinye izinto kuzoholela ku-BF futhi ukuhlanganiswa kwezinto ezibonakalayo akusondeli, kulula ukukunqamula kundaba, okuholela ekutheni I-BFRP umthelela wokuthuthukisa ukusebenza awukwazi ukufinyelela kokulindelekile, noma unciphise amandla okuqala wento kanye nesenzakalo sokumelana namanzi. Inqubo yokuhlanganisa i-impregnation ikhiqiza izinto eziyisisekelo ze-BFRP ezinokunemba okuphezulu kwezinombolo. Ngakho-ke, ukuthola ukusebenza okuphezulu okwengeziwe I-BFRP, izidingo zesilinganiso se-BF nezinye izilungisi nezinto zokwakha kanye nezimo zokuhlanganisa ngaphansi kukamatikuletsheni ahlukene ziqine kakhulu. Kodwa-ke, sisekhona indawo yocwaningo olunzulu mayelana nokwenza kahle izilinganiso zokuhlanganisa nezinqubo enqubweni eyinhlanganisela.

2 Ukushintsha ibhodlela

Njengamanje, ukuguqulwa kwe-fiber interface kusetshenziselwa ikakhulukazi ukuxazulula inkinga ye-fiber-material bonding in I-BFRP. Nakuba zonke zingafinyelela injongo yokwandisa indawo ethile engaphezulu namandla okubopha phakathi kwezindawo zokusebenzelana, indlela ngayinye yokuguqula inemikhawulo ethile, njengokungakwazi ukwenza ukukhiqizwa ngobuningi, ukungcolisa imvelo, nezinqubo eziyinkimbinkimbi. Nakuba izinhlobo eziningi zokuguqulwa okuyinhlanganisela zingafinyelela inhloso yokugcwalisa izinzuzo zomunye nomunye, okwamanje, kukhona ukushoda kokuhlaziya okuhlelekile kwecala lesilinganiso esilinganayo, umphumela wokuguqulwa, kanye nokusetshenziswa kwangempela kokuguqulwa kwenhlanganisela yesixhumi esibonakalayo se-BF ngaphansi kukamatikuletsheni ahlukene. Ukuxuba ifayibha kungadlala umphumela ohambisanayo oyingxubevange, kodwa kunezici eziningi ezithinta umphumela wokuthuthukisa wokuxutshwa kwefayibha. Ubude obuhlukene nezinhlobo zemicu zingafinyelela imiphumela ehlukene yokuqinisa, futhi amanani amaningi noma amancane okuxuba azothinta umphumela wokuqinisa, ahluleke ukufeza imiphumela elindelekile, futhi anciphise ngisho nokusebenza kwento ngokwayo. Nakuba kukhona izifundo ezimayelana nobude obulungile bokuhlanganisa, umthamo, kanye nedatha yokuthuthukisa ukusebenza kwe-BF ngaphansi kukamatikuletsheni ahlukene, inqubekelaphambili yocwaningo ngenqubo yokuthuthukisa ukuhlanganisa ngokusekelwe ezintweni ezihlukene yehlukile, futhi kunokuntuleka kocwaningo oluhlelekile nokufingqa ngezinhlobo, ubude, izilinganiso, imithamo kanye nezinqubo zokuhlanganisa zemicu ehlanganisiwe.

3 Ubunzima bokusebenza

Ukuqinisa isakhiwo sokwakha, kanye nokugandaywa komgwaqo wezokuthutha yi-BFRP esetshenziswa kakhulu, inani elikhulu kunawo wonke lokuqondisa. Iningi lenqubo yokuxuba okuqondile kanye nokhonkolo, inhlabathi, i-asphalt, i-gypsum, nezinye i-BFRP eziyinhlanganisela. Inani layo elengeziwe liphansi, futhi ucwaningo lwamanje ngemikhiqizo enjalo lugxile kakhulu emandleni ezibonelo ze-BFRP, Ukumelana Nokugqwala, i-porosity, njll., nokho, zimbalwa zezinto ezingenhla ezinhlelweni zangempela zobunjiniyela endaweni yokusebenza kwezibalo nocwaningo.I-BFRP ekukhiqizweni kwezimoto okungasindi kanye namandla aphezulu, izinto ze-aerospace ezingasindi ezisezingeni eliphezulu, izicelo zamapayipi okumelana nokugqwala okunamandla aphezulu, njll. azanele kancane. Nokho, kunezibalo ezimbalwa kanye nezifundo ngokusebenza kwe I-BFRP ezinhlelweni zobunjiniyela zangempela. Isibonelo, ukwelashwa kokuphela kwepayipi le-polymer ehlanganisiwe ye-thermoplastic kanye nobuchwepheshe bokuxhuma amapayipi kusenephutha, mayelana nokumelana nokucindezela okuphezulu, ipayipi likawoyela le-BFRP kanye ne-casing kunemikhawulo emikhulu.
