Qhov sib txawv tseem ceeb ntawm flocculation thiab deflocculation yog tias flocculation yog tsim ntawm flocs los ntawm clumping ntawm cov khoom zoo, whereas deflocculation yog dispersion ntawm flocs los tsim ib tug ruaj khov colloid.
Flocculation yog hais txog kev tsim cov clumps los ntawm cov khoom zoo hauv ib qho colloid. Cov kab no hu ua flocs. Peb feem ntau siv lo lus no hais txog kev tshem tawm. Deflocculation, ntawm qhov tod tes, yog qhov ntxeev ntawm flocculation.
Flocculation yog dab tsi?
Flocculation yog tsim ntawm pawg los ntawm kev sib sau ntawm cov khoom zoo hauv kev ncua. Cov kab no hu ua flocs lossis flakes. Flocculation tej zaum yuav tshwm sim spontaneously los yog vim muaj ntxiv ntawm ib tug clarifying tus neeg sawv cev. Txawm li cas los xij, qhov kev tsim floc no txawv ntawm nag lossis daus. Nws yog vim hais tias, nyob rau hauv nag lossis daus, yaj Cheebtsam tsim ib tug khoom thaum nyob rau hauv flocculation, undissolved Cheebtsam tsim ib tug solid.
Daim duab 1: Flocculation
Tom qab tsim cov floc, nws yuav ntab mus rau sab saum toj ntawm kev ncua, nyob rau hauv qab lossis tawg los ntawm kev ncua. Yog hais tias cov flocs nyob rau sab saum toj ntawm kev ncua, peb hu nws "creaming", thiab yog hais tias lawv nyob rau hauv qab, peb hu nws "sedimentation".
Dab tsi yog Deflocculation?
Deflocculation yog qhov tawg ntawm flocs hauv kev ncua. Deflocculants tuaj yeem ua rau qhov no tshwm sim los ntawm kev ua kom muaj peev xwm zeta (qhov muaj peev xwm sib txawv uas muaj nyob nruab nrab ntawm qhov chaw ntawm cov khoom siv rau hauv cov kua ua kua (e.g. dej) thiab cov kua dej ntau) thiab lub zog tawm tsam ntawm cov khoom.
Nyob rau hauv lub deflocculated ncua kev kawm ntawv, collide particles ua raws li ib tug hais, thiab tsis muaj flocs los yog aggregates. Ntawm no, tus nqi sedimentation qeeb vim tias cov khoom me me dua li cov pawg loj ntawm cov khoom muaj feem cuam tshuam rau kev daws teeb meem. Tus supernatant yeej ib txwm muaj cloudiness nyob rau hauv ib tug deflocculated ncua kev kawm ntawv.
Qhov txawv ntawm Flocculation thiab Deflocculation yog dab tsi?
Qhov sib txawv tseem ceeb ntawm flocculation thiab deflocculation yog tias flocculation yog tsim ntawm flocs los ntawm clumping ntawm cov khoom zoo hos deflocculation yog dispersion ntawm flocs los tsim ib tug ruaj khov colloid. Ntxiv mus, flocculation tshwm sim thaum qhia meej cov neeg sawv cev ntxiv thaum deflocculation tshwm sim thaum ntxiv deflocculants.
Tsis tas li ntawd, lwm qhov sib txawv tseem ceeb ntawm flocculation thiab deflocculation yog tias flocculation txo cov viscosity ntawm kev ncua, thaum deflocculation nce viscosity ntawm kev ncua. Yog li ntawd, tus nqi ntawm sedimentation nyob rau hauv ib tug flocculated ncua kev kawm ntawv yog siab tshaj tus nqi sedimentation nyob rau hauv ib tug deflocculated ncua kev kawm ntawv.
Summary – Flocculation vs Deflocculation
Hauv luv luv, flocculation thiab deflocculation yog cov txheej txheem uas cuam tshuam rau ib leeg. Qhov sib txawv tseem ceeb ntawm flocculation thiab deflocculation yog tias flocculation yog tsim ntawm flocs los ntawm clumping ntawm cov khoom zoo, whereas deflocculation yog dispersion ntawm flocs los tsim ib tug ruaj khov colloid.
