Izici zeitheyiphu yokuvala yomsindo ophansi:
Iitheyiphu yokuvala yomsindo ophansiinganciphisa umsindo osetshenziswayo futhi iyiteyipu ekahle yokunciphisa umsindo ezindaweni zokusebenza zezimboni.
Isetshenziselwa ukuvala ezindaweni ezithule zokukhiqiza kanye nendawo elawulwa imvelo.
Incazelo yomkhiqizo:
I-Viscosity: Amandla okunamathela aqine kakhulu, ukusetshenziswa kweglue iyunifomu, ukusetshenziswa kweglue iyunifomu, ukusetshenziswa kanye, akukwazi ukuphinda kusetshenziswe ngemva kokunamathisela isihloko.
Izici zeitheyiphu yokuvala yomsindo ophansi: Kuthulile, kuhambisana nemvelo, ukulwa nokuguga, ukugcina isikhathi eside, isikhathi sokugcina isikhathi eside, umphumela ongcono, futhi kungcono ukukusebenzisa esimweni sezulu esishisayo.
Ukusetshenziswa kweitheyiphu yokuvala yomsindo ophansi: Isetshenziselwa ukupakishwa okuyizinqwaba noma ukuvalwa kwezimpahla ezimbonini ezihlukahlukene, itheyiphu yokuphrinta ingase isetshenziselwe izimpawu zokuxwayisa zomkhiqizo, ukukhushulwa komkhiqizo, njll.
