Emkhakheni wamakhemikhali wansuku zonke, imithi, ukudla, njll., ukuklama nokukhiqizwa kokugcwalisa okuzenzakalelayo & imigqa yokupakisha kuqondiswa ikakhulukazi izidingo zamakhasimende.Wonke umugqa wokugcwalisa usondelene kakhulu nenqubo yokukhiqiza yekhasimende, isivinini sokugcwalisa nokunemba kokugcwalisa.
Ukwahlukaniswa kwemikhiqizo ezifundazweni ezahlukene: impushana, Namathisela nge-viscosity ephansi kanye ne-fluidity enhle, Namathisela nge-viscosity ephezulu nokugeleza okubi, uketshezi olunokugeleza okuhle, uketshezi olufana namanzi, umkhiqizo oqinile.Njengoba imishini yokugcwalisa edingekayo yemikhiqizo emazweni ahlukene ihlukile, lokhu kubuye kuholele ekuhlukeni nasekuhlukeni komugqa wokugcwalisa.Umugqa ngamunye wokugcwalisa nokupakisha ufaneleka kuphela kumakhasimende amanje abenziwe ngokwezifiso.
