Izindaba

I-BFRP inezinzuzo eziningi maqondana nokusebenza kwayo, kodwa intuthuko yayo isabhekene nobunzima obuningi maqondana nezindleko, ubuchwepheshe, ukusetshenziswa, amazinga kanye nemfundo yemakethe. Imboni idinga ukuqinisa ucwaningo lobuchwepheshe kanye nentuthuko, ukunciphisa izindleko zokukhiqiza, ukuthuthukisa amazinga afanele, kanye nokuthuthukisa ukuqwashisa kwabasebenzisi nge-BFRP ngokukhuthazwa kwemakethe ukuze kukhuthazwe ukusetshenziswa kwayo ezindaweni eziningi.

Njengoba isidingo sezinto ezingangcolisi imvelo sikhula, imicu ye-basalt ithola ukunakwa kancane kancane emikhakheni eyahlukahlukene ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba nezamakhemikhali. Nakuba ukusetshenziswa kwayo kuye kwafezwa emikhakheni efana nokwakhiwa kwemigwaqo kanye nezinto zokuhlunga, kusenendawo enkulu yocwaningo lwesikhathi esizayo. Okulandelayo umbono ngocwaningo lwemikhiqizo ye-basalt fiber.

Njengomuguquli ojwayelekile wezinto ezingaphili, i-basalt fiber iye yafundwa kabanzi futhi yasetshenziswa ezintweni ze-asphalt. Izakhiwo zayo eziyingqayizivele azigcini nje ngokuthuthukisa amaphutha e-asphalt ngokwayo kodwa futhi zithuthukisa kakhulu ukusebenza komgwaqo wekhonkrithi ye-asphalt. Ukuqonda okujulile kwendlela esebenza ngayo imicu ye-basalt kubaluleke kakhulu ekwenzeni ngcono ukwakheka nokusetshenziswa kwezingxube ze-asphalt.

Enqubweni ende yokuziphendukela kwemvelo komhlaba, i-basalt, njengomthombo wemvelo obalulekile, ukuvela kwawo okuhlukile kanye nokusabalala okubanzi kwenza kube yinto eluhlaza efanelekile yokukhiqiza imicu ye-basalt esebenza kahle kakhulu. Kuleli phepha, sizoxoxa ngezici, izindlela zokukhetha kanye nenqubo yokwelapha i-basalt.

Umthetho waseYurophu wokuqeda intela yemikhiqizo ye-basalt engenisiwe umenyezelwe futhi wamukelwa namuhla eNgqungqutheleni Yonyaka Yenhlangano Yokuklama Okuluhlaza Yomhlaba ka-2024 kanye neNgqungquthela yaseBrussels eBrussels, eBelgium

Ukuqinisa i-basalt fiber kuyinto izinto zokusetshenziswa ze-basalt fiber kanye nezinto ze-organic resin matrix ngokwesilinganiso esithile sokuhlanganiswa futhi kufakwe inani elifanele lezinsiza kanye nokwakheka kwezinto ezintsha ezihlanganisiwe ezisebenza kahle, emkhakheni wobunjiniyela bomphakathi kunamathuba amakhulu okusetshenziswa.

I-Basalt fiber iyi-modifier evamile ye-inorganic kwelinye, abacwaningi bathole ukuthi i-modifier izongezwa ezintweni ze-asphalt, hhayi nje kuphela engabhekana nezici ezimbi ze-asphalt, kodwa futhi ithuthukise ukusebenza komgwaqo wekhonkrithi ye-asphalt. Kwatholakala ukuthi i-fiber ingathuthukisa ukusebenza kwezingxube ze-asphalt, imicu ezingxubeni ze-asphalt ibe yisimo sesigaba esihlakazekile esinezinhlangothi ezintathu ikhona, ukwakheka kokuqina kwesakhiwo se-spatial mesh kunquma ikhwalithi yokusebenza komgwaqo kwezingxube ze-asphalt. Ngakho-ke, ukuqonda indima yendlela yokusebenza kwe-basalt fiber, yokutadisha izingxube ze-asphalt kubaluleke kakhulu.

Enqubweni yokukhiqizwa kwefayibha eqhubekayo ye-basalt, ukuze kuthuthukiswe ikhwalithi yefayibha, kufanele uzame ukugwema ukuguguleka kwefayibha enqubweni yokukhiqizwa, ngesikhathi esifanayo ngezinhlelo ezahlukene kudinga imicu enezakhiwo ezahlukene zobuso, ngakho-ke enqubweni yokukhiqiza ngokuvamile idinga ukugcotshwa ngamafutha ebusweni befayibha, imboni ibizwa ngokuthi i-infiltration agent. Ukusetshenziswa kwe-infiltration agent ngakolunye uhlangothi kungadlala indima yokuvikela ekugcotshweni ukuze kugwenywe umonakalo ebusweni befayibha, okwesibili kungathuthukisa nokusebenzisana phakathi kwama-monofilaments efayibha, ukuze kunikezwe indima ethile eqenjini, kanti okwesithathu kungaklanywa ngesakhiwo se-infiltration agent uqobo ukuze kuthuthukiswe izakhiwo zobuso befayibha ukuze kuhlangatshezwane nezidingo ezahlukene zohlelo lokusebenza.

Izakhiwo zemishini zemicu ye-basalt (isb., amandla okudonsa, i-modulus yokuguquguquka, ukuqina kokuphuka, njll.) ziyizinkomba ezibalulekile zokusetshenziswa kwazo ezinhlanganisela nasebunjiniyelani. Ukuguqulwa kwendawo akugcini nje ngokuthuthukisa izakhiwo zokubopha phakathi kwemicu nezinto ze-matrix kodwa futhi kungathinta izakhiwo zemishini zemicu ngokwazo. Le miphumela iyahlukahluka kuye ngokuthi indlela yokuguqula isetshenziswa kanjani kanye nenqubo yokwelapha. Okulandelayo ukuhlaziywa okuqhathanisayo komthelela wezindlela eziningana zokuguqula ezivamile ezimpahleni zemishini zemicu ye-basalt.

I-Basalt fiber iyi-fiber engaphili esebenza kahle kakhulu esetshenziswa kabanzi kwezobunjiniyela bezokwakha, izinto ezihlanganisiwe kanye nokuvikelwa kwemvelo ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ukumelana namakhemikhali kanye nokuqina kokushisa okuphezulu. Kodwa-ke, ngenxa yobuso bayo obubushelelezi kanye nokuntuleka kwamaqembu asebenzayo asebenzayo, ukusebenza kokubopha phakathi kwezinto nezinto ze-matrix kubi. Ngokushintsha ubuso, izakhiwo zokubopha phakathi kwezinto ze-basalt fibers zingathuthukiswa kakhulu, ngaleyo ndlela kuthuthukiswe ukusetshenziswa kwazo ezintweni ezihlanganisiwe kanye nezinkambu zokuvikela kwemvelo.
