Izityalo zokuxuba i-asphalt zenziwe ngeenkqubo ezininzi, nganye yazo inemisebenzi eyahlukeneyo. Inkqubo yokutshisa ingundoqo ekusebenzeni kwezixhobo kwaye inempembelelo enkulu ekusebenzeni nasekukhuseleni izixhobo. Kule mihla, obunye ubuchwephesha bamazwe angaphandle buhlala busebenzisa iinkqubo zokutsha kwegesi, kodwa ezi nkqubo zibiza imali eninzi kwaye azifanelekanga kwezinye iinkampani.

E-China, iinkqubo zokutsha ezisetyenziswa ngokuqhelekileyo zinokwahlulwa zibe ziintlobo ezintathu ezahlukeneyo, ezizezi, ezisekelwe kumalahle, ezisekelwe kwi-oyile kunye ne-gas-based. Emva koko, malunga nenkqubo, kukho iingxaki ezininzi eziphambili, ngokukodwa kubandakanywa ukuba umlotha oqulethwe kwipowder yamalahle yinto engenakutsha. Ukuchatshazelwa yinkqubo yokufudumala yesityalo sokuxuba i-asphalt, ininzi yomlotha ingena kumxube we-asphalt. Ngaphezu koko, umlotha u-acidic, oya kunciphisa ngokuthe ngqo umgangatho womxube we-asphalt, ongenakuqinisekisa ubomi benkonzo yemveliso ye-asphalt. Ngelo xesha, i-powder yamalahle ivutha ngokukhawuleza, ngoko kunzima ukutshisa ngokupheleleyo ngexesha elifutshane, okubangela ukuba amafutha aphantsi kunye nokusetyenziswa kwamandla.
Akunjalo kuphela, ukuba amalahle asetyenziswa njengamafutha, ukuchaneka kwemveliso enokuthi kuphunyezwe kwizixhobo zendabuko ezisetyenziselwa inkqubo yokucubungula, enciphisa ngokuthe ngqo ukuchaneka kwemveliso yomxube. Ngaphezu koko, ukutshiswa komgubo wamalahle kwizityalo zokuxuba i-asphalt kufuna igumbi elikhulu lokutshisa, kunye nezinto eziphikisayo kwigumbi lokutsha zizixhobo ezisengozini, ezifuna ukuhlolwa rhoqo kwaye zitshintshwe, kwaye iindleko zokugcinwa ziphezulu.
Ke, ukuba irhasi isetyenziswa njengesixhobo ekrwada, izinga lokusetyenziswa liphezulu kakhulu linokuphunyezwa. Le nkqubo yokutsha iyakhawuleza kwaye inokonga ixesha elininzi. Nangona kunjalo, inkqubo yokutsha yezityalo zokuxuba i-asphalt ezibaswa yigesi nazo zineentsilelo ezininzi. Kufuneka idibaniswe kwipayipi yegesi yendalo, engafanelekanga kwiimeko apho kufuneka ihambe okanye isoloko ifuna ukufuduswa. Ngaphezu koko, ukuba umbhobho wegesi yendalo ukude, kuya kubiza imali eninzi ukuseta iivalvu kunye nokubeka imibhobho kunye nezinye izixhobo ezincedisayo.
Ngoko ke, kuthekani ngenkqubo yokutshisa esebenzisa ioli yamafutha njengamafutha? Le nkqubo ayikwazi ukugcina iindleko zemveliso kuphela, kodwa yenza kube lula ukulawula ukushisa kweoli. Inkqubo yokutsha yezityalo zokuxuba i-asphalt ezibaswa yi-oyile ye-fuel ineenzuzo ezilungileyo zoqoqosho, kwaye inokufumana amandla okutsha afanelekileyo ngokulawula ubuninzi beoli yeoli.
