Peb cov khoom tseem ceeb: block silicone, hydroxilic silicone, carbon monoxent (fluorone, Uzbekistan, thiab lwm yam
Lub zog coj cwj pwm ntawm surfactants cuam tshuam rau saum npoo nro.
Qhov nro ntawm surfactants nthuav qhia cov cwj pwm sib txawv kinetic, uas nyob ntawm tsis tsuas yog pom thiab kub, tab sis kuj nyob rau hom lossis sib xyaw ntawm surfactants. Qhov nro ntawm qee cov surfactants txo qis sai thaum pib, thiab tom qab ntawd txo qis dua raws li lub sijhawm. Ntawm qhov tsis sib xws, txo qis hauv cov nro ntawm lwm cov surfactants yog ntau tas li thiab yuav luag linear.
Daim duab no qhia txog ntau qhov sib txawv nkhaus nkhaus. Lub zog coj tus cwj pwm yuav tsum rau surfactants nyob ntawm daim ntawv thov teb. Raws li daim duab hauv qab no, surfactants c thiab d yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem dynamic vim tias lawv muaj ntau txo cov txheej txheem nro los ntawm thaum pib. Qhia siv surfactants A thiab B rau cov haujlwm tsis muaj zog.
Cov nyhuv ntawm surfactants ntawm thaj kev nro nyob ntawm seb kub.
Qhov nro ntawm cov kua thiab cov txiaj ntsig ntawm surfactants ntawm thaj kev nro nyob ntawm seb kub. Ib qho ntxiv, vim muaj lub zog ntau dua thermal, qhov muaj zog ntawm surfactant molecules nce. Feem ntau, cov nro loj txo qis nrog kev nce qib. Raws li qhov tshwm sim, cov yam ntxwv ntawm cov kua uas muaj surfactants yog cuam tshuam los ntawm qhov kub hloov. Nyob ntawm cov khoom, qhov cuam tshuam kub yuav muaj qhov zoo lossis tsis zoo rau cov yam ntxwv uas xav tau. Txhawm rau tiv thaiv cov kev hloov tsis zoo, lwm yam surfactants lossis diluted daws yuav tsum tau ntxiv cais.
Xijpeem, nws yog ib qho tseem ceeb heev kom nkag siab yuav ua li cas cov nro muaj kev cuam tshuam los ntawm qhov kub hloov.
Ntawm qhov kub thiab txias, tsis yog-ionic surfactants nyob rau hauv dej yog tsis soluble thiab daim ntawv sau ua ke nrog ntau tus nqi ntawm surfactants. Vim tias cov tee dej no, cov tshuaj ua cov tshuaj turbid. Cov yam ntxwv ntawm cov tsis yog-ionic surfactants yog qhov ntsuas kub tshwj xeeb hu ua huab cua taw tes lossis theem hloov pauv kub. Qhov ze dua cov kev ntxuav kom huv ntawm cov tsis muaj ionic thiab cov tshuab surfactant yog rau cov txheej txheem huab, qhov zoo dua kev nyiam huv tuaj yeem txhim kho. Cov tshuaj ntxiv uas tsim nyog tuaj yeem siv los kho cov huab taw tes raws li qhov xav tau ua haujlwm kub.
Meter ceeb toom tau yooj yim rau kev soj ntsuam cov kev tshawb fawb thiab kev txhim kho thiab kev txhim kho, thiab cov khoom ua tau zoo.
Los ntawm kev kho lub neej lub neej, ntau dua, cov npuas lub neej, kom muaj nuj nqis npuas, kom muaj nuj nqis ruaj khov, ntsuas qhov ntsuas kub mus tas li. Yog li ntawd, tus cawv ntawm cov laus qub (kua cua interface) ntawm qhov nro yuav tsis quav ntsej. Qhov no ua rau ntsuas ntsuas mus tau ntev ntawm cov nyhuv ntawm cov nyhuv ntawm cov kev daws teeb meem surfactant nrog qhov tsis muaj.
Ib ob-txheej iav ntim nrog cov dej kub kub tuaj yeem cia li ntsuas qhov kev hloov pauv ntawm cov npoo av sib txheeb ze rau qhov kub. Yog li, cov txiaj xeem ntawv muab cov ntaub ntawv tseem ceeb rau kev tshawb fawb thiab kev txhim kho cov ntawv thov kev zoo ntawm cov khoom lag luam hauv daim ntawv thov daim ntawv thov.
