Viscometers yog qhov tseem ceeb nyob rau ntau thaj chaw. Ua ntej, daim ntawv thov tus nqi ntawm kev tuaj saib xyuas tsis tau zoo hauv cov tshuaj pleev ib ce kev lag luam yog xav tau cov khoom lag luam kom zoo, tsim cov khoom lag luam tshiab, thiab ua cov tshuaj tshiab, thiab ua kev tswjhwm tshiab. Los ntsuas ntsuas cov tshuaj pleev ib ce ntawm cov tshuaj pleev ib ce, nws yog qhov ua tau kom ntseeg tau tias lawv muaj qhov tsim nyog yooj yim thiab ductility thaum thov lossis siv. Piv txwv, daim di ncauj yuav tsum muaj viscosity siab kom zoo rau thiab tiv thaiv daim tawv nqaij, thaum lub cev ua kom muaj zog los ntws tawm ntawm cov dispenser.
Lub sijhawm tsim kho, kev mus ntsib cov kev tuaj yeem pab cov kev cuam tshuam ntawm cov tshuaj pleev ib yam ntawm cov tshuaj pleev ib ce, thiab tsim cov khoom lag luam tshiab thiab kev ruaj khov los ntawm kev kho cov mis
Ib qho ntxiv, cov kev tuaj saib xyuas mus kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb thiab kev txhim kho cov ntaub ntawv tshiab. Los ntsuas cov yam ntxwv sib txawv ntawm cov ntaub ntawv sib txawv, cov neeg tshawb xyuas tuaj yeem ntsuas cov khoom ua haujlwm thiab cov peev txheej tshiab, yog li siv cov khoom lag luam tshiab.
Thib ob, cov neeg tuaj saib pom muaj ntau yam ntawm daim ntawv thov tus nqi hauv kev lag luam ntau lawm. Nws yog siv los soj ntsuam cov viscosity ntawm cov kua dej thaum lub sijhawm tsim khoom los xyuas kom muaj kev sib xws ntawm cov khoom lag luam zoo. Piv txwv li, hauv cov txheej txheem ntau lawm ntawm cov tshuaj polymer, los ntawm kev soj ntsuam lub viscosity ntawm cov tshuaj pleev ib ce, cov tshuaj tiv thaiv tuaj yeem tswj tau cov khoom zoo thiab zoo ntawm cov khoom kawg.
Hauv kev tshawb fawb ntawm kev tshawb fawb kuj tseem ua lub luag haujlwm tseem ceeb hauv kev kawm txog lub cev thiab tshuaj coj tus cwj pwm ntawm cov kua hauv qab. Cov kev tshawb fawb no yog qhov tseem ceeb rau kev nkag siab cov khoom tseem ceeb ntawm cov kua dej, tsim cov txheej txheem tshiab thiab txhim kho cov txheej txheem kev lag luam tshiab. Thaum kawg, tus viscepeters tseem muaj cov ntawv thov tseem ceeb hauv kev kho mob. Ntsuas cov ntshav thiab lub cev ua kua yog ib qho kev kuaj mob lossis cov kab mob nyuaj xws li cov kab mob plawv thiab mob qog noj ntshav. Los ntsuas ntsuas cov kua viscosity thaum cov txheej txheem, cov ntaub ntawv ntawm rheological coj tus nqi rau kev kwv yees tus txheej txheem tswj, kev thauj khoom, kev ua haujlwm ntawm cov khoom lag luam.
