Kusukela ekuqinisekiseni izimpawu namamaki, ukuhlola uzibuthe, kuya ekusebenziseni i-nitric acid ukuhlola ubuqiniso bento esetshenziswayo, kukhona amasu obuchwepheshe ahlukene onawo ukuze uhlukanise igolide elimsulwa kumaalloyi avamile. Kodwa-ke, kubalulekile ukuqaphela ukuthi lezi zivivinyo kufanele zenziwe ochwepheshe abanolwazi emkhakheni, njengoba zidinga ulwazi lobuchwepheshe namakhono akhethekile ukuze kuqinisekiswe imiphumela enembile futhi kugwenywe ukulimala kobucwebe okukhulunywa ngabo. Ngokufanayo, kubalulekile ukuqaphela ukuthi isisindo, ubukhulu kanye nomklamo wocezu lobucwebe akunikezi izinkomba eziqinile mayelana nobuqiniso begolide elisetshenzisiwe. Ngakho-ke, kuhlale kululeka ukuthi ufune iseluleko kumajewele athembekile futhi azinzile.
izinhlangano ezikhethekile ezinganikeza isiqinisekiso nesitifiketi sobuqiniso nekhwalithi yobucwebe begolide. Ngolwazi nokusebenzisa lezi zindlela zokuhlonza, uzohlonyiswa kangcono ukwenza izinqumo ezinolwazi ekusesheni kwakho ubucwebe begolide bangempela. Khumbula ukuthi ukuthenga ubucwebe bekhwalithi kuwutshalomali oluhlala njalo kanye nobufakazi bokunambitheka kwakho okuhle, ngakho-ke kuzofaneleka umzamo wokuqinisekisa ubuqiniso bakho. Sethemba ukuthi lesi sihloko sikunikeze umhlahlandlela ocacile futhi owusizo wokuthi ungasho kanjani ukuthi ucezu lobucwebe luyigolide!
