Ukuguquguquka kokusingqongileyo kweentonga zobhedu zokumelana nokubola

Umphezulu wobhedu uthambekele ekwenzeni ifilimu ekhuselekileyo ye-zinc oxide okanye i-zinc carbonate esisiseko, ebonisa ukuxhathisa okulungileyo kokuhlwa kwiindawo ezingathathi hlangothi okanye ezibuthathaka zealkaline. Kwiimeko ezinobungozi ezifana namanzi olwandle kunye nomoya ofumileyo, ukuxhathisa ukubola kwawo kungaphezulu kunokwentsimbi eqhelekileyo yekhabhoni, kodwa buthathaka kunoko kwentsimbi engatyiwayo. Kubalulekile ukuqaphela ukuba ilothe -iqulethe ibhedu (efana ne-HPb59-}1) ayiphuculi kuphela ukusebenza kokusika kodwa inciphisa i-coefficient ye-friction ngesiphumo sokuthambisa selothe, inika inzuzo ebalulekileyo kumalungu angagugiyo.
