Yog vim li cas rau qhov cuam tshuam ntawm lub tshuab ziab khaub ncaws muaj peev xwm

Flash tshuab ziab khaub ncaws, ua cov cuab yeej ziab khaub ncaws tseem ceeb, raug cuam tshuam los ntawm ntau yam ntawm cov khoom muaj peev xwm. Kev nkag siab txog cov xwm txheej no pab peb nkag siab zoo dua thiab ua kom cov cuab yeej ua tau zoo. Kab lus no yuav txheeb xyuas kom meej tias yam twg tuaj yeem cuam tshuam qhov muaj peev xwm ntawm cov tshuab ziab khaub ncaws.

Ua ntej, morphology ntawm cov khoom siv yog qhov tseem ceeb cuam tshuam rau lub peev xwm ntawm lub tshuab ziab khaub ncaws. Cov khoom siv morphology suav nrog qhov loj me, thaiv qhov loj, thiab cov khoom siv permeability. Piv txwv li, cov khoom loj dua yog qhov nyuaj rau ziab dua li cov khoom me me, thaum cov blocks loj dua yooj yim dua kom qhuav dua cov ntaub ntawv tuab. Qee cov ntaub ntawv, xws li xuab zeb, silica, activated carbon, thiab unglazed ceramics, yog ib qho yooj yim kom qhuav vim qhov qis zog ntawm cov dej noo thiab cov khoom siv.

Qhov thib ob, cov dej noo ntawm cov khoom ntub dej, piv txwv li, qhov feem pua ​​ntawm cov dej noo nyob rau hauv tag nrho qhov hnyav ntawm cov khoom ntub, kuj yog ib qho tseem ceeb cuam tshuam rau lub tshuab ziab khaub ncaws. Qhov siab dua cov ntsiab lus ntawm cov dej noo, qhov ntev ntawm lub sij hawm ziab yuav tsum ncav cuag tib qhov kawg ntawm cov dej noo, yog li cuam tshuam rau lub tshuab ziab khaub ncaws.

Tsis tas li ntawd, hom thiab viscosity ntawm cov khoom kuj cuam tshuam lub peev xwm ntawm lub tshuab ziab khaub ncaws. Piv txwv li, nyob rau hauv cov txheej txheem ziab ntawm capillary ntxeem tau cov ntaub ntawv, noo noo feem ntau yog khi rau cov khoom los ntawm capillary rog, nrog osmotic khi ntawm noo noo rau cov khoom yog cov tseem ceeb daim ntawv. Cov ntaub ntawv no feem ntau pom muaj viscosity siab thiab muaj zog binding lub zog ntawm ya raws thiab cov khoom, ua kom qhuav nyuaj thiab yog li cuam tshuam cov peev txheej ntau lawm.

Tsis tas li ntawd, huab cua kub kub kuj yog ib qho tseem ceeb heev cuam tshuam rau lub peev xwm ntawm cov tshuab ziab khaub ncaws. Hauv ntau lub tshuab ziab khaub ncaws, thaum lwm yam kev mob tseem nyob tas li, lub peev xwm lub cev qhuav dej ntawm lub tshuab ziab khaub ncaws feem ntau yog proportional rau qhov kev hloov ntawm huab cua kub. Thaum xaiv cov khoom siv ziab, nws yog ib qho tseem ceeb kom muaj cov ntaub ntawv txaus ntawm qhov ntsuas kub uas yuav ua rau cov khoom puas tsuaj, thiab, qhov twg cov khoom tso cai, xaiv qhov siab - qhov nruab nrab kub.
