Ngenxa yethonya lezici ezihlukahlukene, izitshalo zokuxuba i-asphalt nakanjani zizoba nezinkinga ngemva kwesikhathi sokusetshenziswa. Ngenxa yokuntula ulwazi, abazi ukuthi bangabhekana kanjani nalezi zinkinga. Umhleli ufingqa ulwazi oluthile namakhono mayelana nalokhu ukuze uthole inkomba yakho.

Ngokusho kokubonakaliswa okuhlukene kwenkinga yesitshalo sokuxuba i-asphalt, isisombululo sihlukile. Isibonelo, lapho izingxenye zesitshalo sokuxuba i-asphalt zonakaliswe ukukhathala, kuyadingeka ukuqala kusukela ekukhiqizeni izingxenye. Ngakolunye uhlangothi, kuyadingeka ukuthuthukisa isiphetho esiphezulu sezingxenye. Ngakolunye uhlangothi, inhloso yokunciphisa ukugxiliswa kokucindezeleka kwezingxenye ingafinyelelwa ngokwamukela ukuhlunga kwe-cross-section okuthambile. Ngaphezu kwalokho, ukusebenza kwezingxenye kungathuthukiswa ngokufaka i-carburizing, ukucisha kanye nezinye izindlela, ukuze kuzuzwe umphumela wokunciphisa ukulimala kokukhathala kwezingxenye.
Kodwa uma ukulimala kwezingxenye zesitshalo sokuxuba i-asphalt kungenxa yokungqubuzana, yini okufanele yenziwe? Indlela elula futhi ephumelela kakhulu ukusebenzisa izinto ezingagqoki ngangokunokwenzeka, futhi lapho uklama ukuma kwezingxenye zezitshalo zokuxuba, zama ukunciphisa ukumelana kwayo nokungqubuzana. Ngaphezu kwalokho, ukugqwala kungenye yezizathu eziholela ekulimaleni kwezingxenye. Kulokhu, ungasebenzisa i-nickel, i-chromium, i-zinc nezinye izinto ezimelana nokugqwala ukuze ucwebeze ubuso bezingxenye zensimbi, noma ugcobe uwoyela phezu kwezingxenye zensimbi, futhi usebenzise upende ovimbela ukugqwala ebusweni bezingxenye ezingezona ezensimbi. ukuvimbela izingxenye ukuthi zingagqwali.
