Ngenxa yempembelelo yezinto ezahlukeneyo, izityalo zokuxuba i-asphalt ngokuqinisekileyo ziya kuba neengxaki emva kwexesha lokusetyenziswa. Ngenxa yokungabi namava, abayazi indlela yokusingatha ezi ngxaki. Umhleli ushwankathela amava athile kunye nezakhono kulo mba kwireferensi yakho.

Ngokweendlela ezahlukeneyo zokubonakaliswa kwengxaki yesityalo sokuxuba i-asphalt, isisombululo sikwahluke. Ngokomzekelo, xa iinxalenye kwisityalo sokuxuba i-asphalt bonakaliswe ukukhathala, kuyimfuneko ukuqala kwimveliso yamacandelo. Ngakolunye uhlangothi, kuyimfuneko ukuphucula umgangatho ogqityiweyo wamacandelo. Ngakolunye uhlangothi, injongo yokunciphisa uxinzelelo loxinzelelo lwamacandelo inokufezekiswa ngokuthatha i-filtration encinci yecandelo. Ukongezelela, ukusebenza kwamacandelo kunokuphuculwa ngokutshisa i-carburizing, ukucima kunye nezinye iindlela, ukuze kufezekiswe umphumo wokunciphisa umonakalo wokukhathala kwamacandelo.
Kodwa ukuba umonakalo wamalungu kwisityalo sokuxuba i-asphalt kungenxa yokukhuhlana, yintoni ekufuneka yenziwe? Eyona ndlela ilula kunye neyona ndlela isebenzayo kukusebenzisa izixhobo zokunxiba kangangoko kunokwenzeka, kwaye xa uyila imilo yamacandelo esityalo sokuxuba, zama ukunciphisa ukuxhathisa kwayo. Ukongeza, i-corrosion sesinye sezizathu ezikhokelela kumonakalo wamalungu. Kule meko, ungasebenzisa i-nickel, i-chromium, i-zinc kunye nezinye izinto ezichasene nokuhlwa ukuze udibanise umphezulu weendawo zetsimbi, okanye usebenzise i-oyile kumphezulu weendawo zetsimbi, kwaye usebenzise ipeyinti echasene ne-corrosion kumphezulu weendawo ezingezona zetsimbi. ukuthintela iindawo ekudlekeni.
