Kev sib tov

Niaj hnub no, daim ntawv thov ntawm kev sib xyaw tshuab yog ntau thiab ntau dua, txawm tias los ntawm kev lag luam kev lag luam lossis kev ua neej nyob txhua hnub, kev sib xyaw tshuab yuav siv tau. Feem ntau hais lus, nplawm yog sib tov ob lossis ntau cov ntaub ntawv nrog ib leeg nyob rau hauv qhov kev txiav txim ntawm quab yuam.

Cov txheej txheem sib xyaw sib txawv yuav txawv, vim tias lawv cov kev sib xyaw ua ke hauv kev tsim khoom lag luam yog qhov nyuaj dua, thiab cov khoom sib txawv thiab cov txheej txheem ntau lawm yuav tsum ua tiav cov teebmeem sib txawv. Cov txheej txheem sib xyaw tuaj yeem muab faib ua: homogeneous sib tov, khoom-kua ncua kev kawm, kua-kua dispersion, khoom tawg, roj-kua dispersion. Tom ntej no, Wuxi Jiangke yuav tham txog lub luag haujlwm ntawm cov txheej txheem sib txawv.

Homogeneous mixing: homogeneous mixing yog hais txog kev sib xyaw ntawm cov kua dej sib tov. Nyob rau hauv cov txheej txheem sib xyaw ua ke, qhov tseem ceeb ntawm kev tswj hwm yog qhov kev sib tw, thiab cov nyhuv shear ntawm cov khoom sib xyaw ntawm cov khoom yog qhov thib ob. Txawm li cas los xij, thaum lub viscosity ntawm cov khoom sib xyaw ua ke yog qhov sib txawv heev, qhov kev txiav txim siab ntawm cov agitator yuav ua rau cov kua nrog ntau dua viscosity disperse zoo nyob rau hauv lub thawv.

Cov khoom ua kua raug tshem tawm: cov khoom ua kua raug tshem tawm yog hais txog kev tshem tawm cov khoom hauv cov kua nrog kev pab los ntawm cov agitator los tsim cov khoom sib xyaw ua kua lossis kev ncua. Uniform suspension feem ntau yog nyob ntawm qhov ceev ntawm kev ncig thiab kev siv ntawm turbulence. Rau cov khoom siv-kua raug tshem tawm, nws yog ib qho tsim nyog yuav tsum tau siv cov stirrer nrog kev kub ceev, thiab nws yog qhov zoo dua los siv qis baffle thiab phab ntsa baffle thaum sib tov khoom.

Cov kua ua kua dispersion: kua kua dispersion yog hais txog cov dispersion ntawm cov ntaub ntawv uas tsis muaj viscosity thiab immiscible nrog ib leeg. Rau cov ntaub ntawv uas tsis tshua muaj viscosity thiab immiscible nrog ib leeg, qhov yuav tsum tau rau shear thiab ncig yuav siab dua. Rau cov ntaub ntawv uas tsis tshua muaj viscosity thiab immiscible nrog ib leeg, cov khoom siv sib xyaw nrog cov shear quab yuam loj thiab cov peev txheej loj yuav tsum raug xaiv.

Khoom dissolution: khoom dissolution yog to taub zoo, uas yog, cov khoom yog yaj nyob rau hauv lwm yam ntaub ntawv nyob rau hauv daim ntawv ntawm stirring. Cov nyhuv ntawm shearing ntawm cov khoom tawg yog me me, yog li cov khoom tawg tuaj yeem ua tiav nrog lub stirrer nrog me me shearing muaj peev xwm thiab siab ncig.

Gas kua dispersion: gas kua dispersion yuav tsum gas dispersion los tsim kom txaus successive contact nto, uas yog conducive rau gas nqus. Cov txiaj ntsig tseem ceeb ntawm cov roj-kua dispersion yog lub zog shear. Cov khoom siv agitator siv yuav tsum muaj cov nyhuv shearing ntawm cov roj.
