Tag nrho kev ncua , suav nrog ntxhib emulsions, yog qhov tseeb thermodynamically tsis ruaj khov . Lawv yuav, los ntawm random txav ntawm cov khoom nyob rau lub sij hawm, aggreg vim yog lub ntuj thiab tseem ceeb nyiam kom txo tau qhov loj tshwj xeeb deg cheeb tsam thiab tshaj nto zog.

Tsuas yog li ntawd, kev ncua kev ruaj ntseg yog dab tsi?

STABILITY OF TSEEM CEEB . Nws yog ib qho tseem ceeb kom nkag siab qhov ntawd kev ncua yog kinetically ruaj khov , tab sis thermodynamically tsis ruaj khov, system. Lub cev ruaj khov yog txhais raws li tus mob nyob rau hauv uas hais tias nyob rau hauv uniformly faib thoob plaws hauv lub dispersion tsis muaj tej yam tshwm sim ntawm sedimentation.

Ib yam li ntawd, kuv yuav ua li cas thiaj li txwv tsis pub kuv qhov kev ncua tsis pub dhau? Caking tej zaum tiv thaiv los ntawm kev tsim kev ncua nrog cov txheej txheem sib koom ua ke uas txhawb nqa cov khoom thiab ua kom lawv tsis txhob nkag mus rau ib qho chaw kaw. Lub network tej zaum yuav muaj tus neeg sawv cev ncua (cov qauv tsheb), cov khoom lawv tus kheej (flocculated), los yog kev sib xyaw ntawm ob.

Ua li no, vim li cas qhov kev ncua sij hawm ruaj khov dua li kev daws teeb meem?

Vim yog lawv tus cwj pwm ua kua, kev ncua sawv cev rau daim foos zoo tagnrho rau cov neeg mob uas muaj teeb meem nqos cov ntsiav tshuaj lossis tshuaj ntsiav. Thaum kawg, tshuaj nyob rau hauv kev ncua yog tshuaj ruaj khov dua hauv daws.

Vim li cas cov particles nyob hauv kev ncua?

A kev ncua yog ib tug heterogeneous sib tov nyob rau hauv uas ib co ntawm cov hais daws tawm ntawm qhov sib tov thaum sawv ntsug. Cov cov khoom hauv a kev ncua yog qhov loj dua cov kev daws teeb meem, yog li lub ntiajteb txawj nqus tuaj yeem rub lawv nqes tawm ntawm qhov nruab nrab dispersion (dej).
