Kumagumbi acocekileyo kwi-microelectronics kunye nemveliso yamachiza, izinto ezahlukeneyo ze-acidic kunye ne-alkaline, i-solvents eziphilayo, iigesi eziqhelekileyo, kunye neegesi ezikhethekileyo zihlala zisetyenziswa okanye zenziwe kwinkqubo yokuvelisa;kwiziyobisi ze-allergenic, i-steroids ethile Kwinkqubo yokuvelisa iziyobisi eziphilayo, izidakamizwa ezisebenzayo kunye netyhefu, izinto ezihambelanayo ezinobungozi ziya kukhutshwa okanye zivuze kwigumbi elicocekileyo.Ngoko ke, izixhobo zenkqubo yokuvelisa okanye iinkqubo ezinokukhupha izinto ezahlukeneyo ezinobungozi, iigesi okanye uthuli kwigumbi elicocekileyo lokuvelisa ezi mveliso zingasentla Cwangcisa isixhobo sokukhupha lendawo okanye isixhobo sokukhupha igumbi elipheleleyo.Ngokohlobo lwerhasi yenkunkuma ekhutshwe ngexesha lenkqubo yokuvelisa, isixhobo sokukhupha (inkqubo) inokwahlulwa ngokufanelekileyo ngokwezi ntlobo zilandelayo.
(1) Inkqubo yokuphuma ngokubanzi
(2) Inkqubo yokukhupha igesi ephilayo
(3) Inkqubo yokukhupha igesi ye-Acid
(4) Inkqubo yokukhupha igesi yealkaline
(5) Inkqubo yokukhupha igesi eshushu
(6) Inkqubo yokukhupha equlethe uthuli
(7) Inkqubo ekhethekileyo yokukhupha igesi
(8) Inkqubo yokukhupha eyingozi kunye netyhefu kwimveliso yeziyobisi
