Khetha uwoyela weketanga lamabhayisikili. Amaketanga amabhayisikili awasebenzisi uwoyela wenjini osetshenziswa ezimotweni nasezithuthuthwini, uwoyela womshini wokuthunga, njll. Lokhu kungenxa yokuthi lawa mafutha anomphumela olinganiselwe wokugcoba eketanga futhi anobuthi obukhulu. Anganamathela kalula enhlabathini eningi noma asakazeke yonke indawo. Kokubili, akuyona inketho enhle yebhayisikili. Ungathenga uwoyela weketanga okhethekile wamabhayisikili. Namuhla, kunezinhlobo ezahlukene zamafutha. Ngokuyisisekelo, khumbula nje izitayela ezimbili: ezomile nezimanzi.
1. Uwoyela weketanga elomile. Usetshenziswa endaweni eyomile, futhi ngenxa yokuthi womile, akulula ukunamathela odakeni futhi kulula ukuwuhlanza; ububi ukuthi kulula ukuwukhipha futhi udinga ukugcotshwa kaningi.
2. Uwoyela weketanga elimanzi. Lifanele ukusetshenziswa ezindaweni ezinomswakama, lifanele imizila enamanzi amile kanye nemvula. Uwoyela weketanga elimanzi uyanamathela futhi unganamathela kuwo isikhathi eside, okwenza ufanelekele ukuhamba ibanga elide. Ububi ukuthi ukunamathela kwawo kwenza kube lula ukunamathela odakeni nasesihlabathini, okudinga ukulungiswa ngokucophelela.
Isikhathi sokugcoba uchungechunge lwebhayisikili:
Ukukhetha amafutha kanye nokuvama kokufaka uwoyela kuncike endaweni osetshenziswa kuyo. Umthetho oyinhloko ukusebenzisa uwoyela one-viscosity ephezulu uma kunomswakama omningi, ngoba i-viscosity ephezulu kulula ukunamathela ebusweni beketanga ukuze kwakheke ifilimu evikelayo. Ezindaweni ezomile nezinothuli, sebenzisa uwoyela one-viscosity ephansi ukuze angangcoliswa uthuli nokungcola. Qaphela ukuthi awudingi uwoyela omningi kakhulu weketanga, futhi zama ukugwema uwoyela onamathela ohlakeni lwesondo lebhuleki noma kwidiski, okunganciphisa ukunamathela kwe-sediment futhi kugcine ukuphepha kokubhuleka.
