Kwiminyaka yakutshanje, ukwenzeka rhoqo kweengozi zomlilo kwinkqubo yokukhusela udonga lwangaphandle lwezakhiwo kuye kwatyhila iziphene eziphambili zokungahambelani phakathi kokuthintela umlilo kunye nokonga amandla kwezinto zokukhusela udonga zemveli. Izinto zemveli ezifana nebhodi yoboya belitye zifunxa amanzi, zande kwaye zinamandla amancinci, ngelixa izinto zokukhusela udonga zendalo (ezifana ne-XPS, i-EPS) ziyatsha kwaye zihlala ixesha elifutshane, ezingenako ukuhlangabezana neemfuno zokhuseleko lwexesha elide lwezakhiwo eziphakamileyo kunye nezakhiwo eziluhlaza. Kodwa ukuvela kwebhodi yefayibha ye-basalt sisisombululo esihle kule ngxaki.

Ungcoliseko lwengxolo kwindalo esingqongileyo lube yingxaki ebalulekileyo echaphazela impilo yabantu kunye nomgangatho wobomi, kunye nezixhobo zoshishino (umz., ii-compressors eziguquguqukayo) ezinegalelo elikhulu. Izixhobo zemveli ezifunxa ingxolo (umz., i-cotton fiber felt) zibonisa ukusebenza okulinganiselweyo kwiindawo eziphezulu kwaye zichaphazeleka ziimeko zokusingqongileyo ezifana nobushushu. I-basalt fiber, izinto ezingaphiliyo ezisebenza kakhulu ezinesakhiwo esineembobo kunye neempawu ze-acoustic eziphezulu, ziye zavela njengendlela efanelekileyo yokusetyenziswa kolawulo lwengxolo.

Ukuveliswa kweefayibha zebasalt okuqhubekayo kusebenzisa "inkqubo yenyathelo elinye", ebonakaliswa ngumsebenzi olula kodwa imiqobo yobugcisa ephezulu. Xa kuthelekiswa nokuveliswa kweefayibha zekhabhoni, iifayibha zebasalt eziqhubekayo zisebenzisa amandla amancinci kakhulu (ngaphantsi kwe-1/10 yamandla okusetyenziswa kweefayibha zekhabhoni) kwaye azikhuphi i-CO₂, i-SO₂, okanye ezinye iigesi eziyingozi, nto leyo eyenza ukuba ibe yindlela yokuvelisa iifayibha zebasalt eziqhubekayo. Izixhobo eziphambili zobushushu zokuveliswa kweefayibha zebasalt eziqhubekayo sisithando somlilo, esahlulwe saba ziindawo zokufudumeza ezisetyenziswa ekutshiseni kunye nezithando zetanki.

I-basalt kunye ne-carbon fiber zinendima ebalulekileyo ekufuneka ziyidlale kwiindawo ezahlukeneyo, kwaye ezi zinto zimbini azikhuphisani ngokupheleleyo, kodwa ziyahambelana.

I-Basalt fiber geogrid luhlobo lwezinto zokuqinisa ubunjineli bokwakha ezenziwe nge-basalt fiber, ekwicandelo le-geosynthetics. Yenziwa ngokunyibilikisa i-basalt ore kubushushu obuphezulu ize emva koko iyitsale ibe yimicu, ize emva koko yenze isakhiwo esifana negridi ngokuluka, ukugquma (njenge-asphalt) kunye nezinye iinkqubo, ezisetyenziswa kakhulu kwiindlela, koololiwe, kumadama nakwezinye iiprojekthi zokuphucula uzinzo nokuqina kwesakhiwo.

Xa kuthelekiswa iipropati zeekhemikhali okanye zemishini nganye, iifayibha zobuchwepheshe obuphezulu ezineempawu ezigqwesileyo kunezo ziqhubekayo ifayibha yebasalt (CBF) inokufumaneka. Nangona kunjalo, xa kujongwa ukusebenza okubanzi, i-CBF ivela njengefayibha "eguquguqukayo" efanelekileyo. Ngaphaya kwamandla ayo aphezulu, i-modulus ephezulu, kunye neempawu zobugcisa eziphambili, i-CBF ibonakalisa ukumelana okugqwesileyo nokugqwala kwe-acid/alkali, amaqondo obushushu aphezulu, imitha, kunye ne-oxidation. Ikwabonisa ubushushu obuhle kakhulu/ukugquma kwe-acoustic, ukusebenza kakuhle kokuhluza, ukubambezeleka komlilo, amandla aphezulu okuxinzelela kunye nokucheba, kunye nokuzivumelanisa nezimo ezimangalisayo kwiindawo ezahlukeneyo. Ezi mpawu ziyenza isebenze ekunciphiseni ubunzima besakhiwo ngelixa kusenziwa izinto ezintsha ezidityanisiweyo.

Ifayibha yeBasalt, njengezinto ezintsha ezingaphiliyo, ezisebenza kakuhle, nezinobuhlobo nokusingqongileyo, iphucula kakhulu iipropati zoomatshini, ukuqina, kunye nokusebenza kwekhonkrithi ekwaziyo ukungena emanzini.

Isingxobo esilukiweyo sefayibha ye-basalt, esisixhobo esisebenza kakuhle kakhulu esiveliswa ngokunyibilikisa nokuzoba ilitye le-basalt lendalo, sifumene udumo kwiminyaka yakutshanje kumashishini afana nokhuseleko lwemizi-mveliso, i-aerospace, kunye namandla avuselelekayo. Iipropati zaso ezikhethekileyo ze-physicochemical kunye neenzuzo ezinobuhlobo nendalo zibonelela ngamathuba amatsha okuphucula izixhobo zemveli. Eli nqaku liphonononga ixabiso eliphambili lesixhobo ngeempawu zaso zesayensi kunye nokusetyenziswa kwangempela.

Ikhonkrithi, njengezinto ezibuthathaka, idla ngokufaka imicu ukuphucula ukusebenza kwayo. Indlela esebenza ngayo i-basalt fiber kwikhonkrithi ibonakala kakhulu kwezi zinto zilandelayo.

Ifayibha yeBasalt njengohlobo lwezinto eziluhlaza eziphezulu zokusebenza, kwiminyaka yakutshanje kwicandelo lokhuseleko lokusingqongileyo ekusetyenzisweni kophando iyaqhubeka nokwanda, ukumelana nokugqwala, ukumelana nobushushu obuphezulu, ukubola kunye nezinye iimpawu zobuchwepheshe bokhuseleko lokusingqongileyo zibonelela ngezisombululo ezintsha.
