Hauv ntiaj teb kev tshawb fawb tshuaj thiab kev lag luam,high pressure lab reactorsua lub luag haujlwm tseem ceeb hauv kev ua kom yooj yim cov tshuaj tiv thaiv nyob rau hauv kev tswj xyuas. Nyob rau hauv lub plawv ntawm cov sophisticated pab kiag li lawm yog ib qho tseem ceeb tivthaiv - lub stirrer los yog agitator. Kab lus no delves mus rau hauv ntau yam kev ua haujlwm ntawm stirrers nyob rau hauv high pressure lab reactors, tshawb xyuas lawv cov kev cuam tshuam ntawm kev sib xyaw ua haujlwm, cov tshuaj tiv thaiv dynamic, thiab tag nrho cov txheej txheem tswj.

 

Lub luag haujlwm tseem ceeb ntawm tus stirrer lossis agitator nyob rau hauv lub siab siab lab reactor yog los txhim kho kev sib xyaw ua haujlwm. Qhov kev ua haujlwm yooj yim zoo li no muaj qhov cuam tshuam zoo rau kev ua tiav thiab rov tsim dua tshiab ntawm cov tshuaj tiv thaiv. Cia peb tshawb txog ntau txoj hauv kev uas stirrers pab txhawb kev sib xyaw kom zoo:

● Homogenization ntawm Reactants

Ib qho ntawm cov luag haujlwm tseem ceeb tshaj plaws ntawm tus stirrer yog los xyuas kom meej qhov sib txawv ntawm cov reactants thoob plaws hauv lub nkoj reactor. Nyob rau hauv ib puag ncig zoo li qub, cov tshuaj reactants tuaj yeem nyob rau hauv cov khaubncaws sab nraud povtseg lossis tsim cov chaw hauv cheeb tsam, ua rau cov tshuaj tiv thaiv tsis sib xws thiab cov khoom siv sab nraud uas tsis xav tau. Lub stirrer txoj kev nruam nruam tiv thaiv no stratification, tswj ib homogeneous sib tov uas txhawb kom muaj kev sib haum xeeb thiab muaj txiaj ntsig zoo.

● Txhim kho kev hloov pauv loj

Stirrers ho txhim kho huab hwm coj hloov pauv hauv cov reactor. Los ntawm kev tsim turbulence thiab kua zog, lawv nce qhov chaw ntawm qhov chaw sib txawv ntawm cov theem sib txawv (piv txwv li, kua-kua, roj-kua, los yog khoom-kua interfaces). Qhov no txhim khu kev sib txuas hauv cheeb tsam nrawm nrawm hloov ntawm cov molecules ntawm theem, uas feem ntau yog ib qho kev txwv cov kauj ruam hauv ntau cov tshuaj tiv thaiv.
