Lub luag haujlwm ncaj qha tshaj plaws ntawm tus neeg sawv cev foaming yog tsim cov npuas dej. Thaum cov pa nkag mus rau hauv cov kua-txawm yog los ntawm kev txhaj tshuaj lossis kev ua kom muaj zog ntawm cov neeg kho tshuab- cov neeg ua npuas dej ua kom yooj yim tsim cov npuas npuas los ntawm kev txo cov kua dej ntawm qhov nro. Hauv cov khoom siv tu, qhov kev ua no tshwm sim raws li cov nplua nuj lather; nyob rau hauv cov khoom noj khoom haus, nws ua rau ob qho tib si pom kev pom thiab cov ntaub ntawv kev paub- piv txwv xws li whipped qe dawb los yog foamy taub hau ntawm ib qho dej haus. Tshaj li tsuas yog tsim ua npuas ncauj xwb, cov neeg ua npuas dej kuj tseem ua haujlwm kom ruaj khov, tiv thaiv nws los ntawm kev tawg ntxov ntxov. Cov molecules surfactant nyob rau hauv cov foaming tus neeg sawv cev ua ib zaj duab xis nyias ntawm cov pa roj-kua interface, thaum auxiliary Cheebtsam -xws li cov proteins, polysaccharides, los yog thickeners- nce cov kua viscosity. Qhov kev sib xyaw ua ke no cuam tshuam cov coalescence ntawm npuas thiab kev khiav tawm ntawm cov pa, yog li ncua lub npuas lub neej. Cov yam ntxwv no yog qhov tseem ceeb ntawm ntau yam kev siv- suav nrog cov tshuaj pleev ib ce, khoom noj khoom haus, thiab cov qauv tsim khoom lag luam- vim nws ua kom muaj kev sib haum xeeb thiab kev ua haujlwm ntev ntawm cov npuas dej.
Nqe 3: Txhim kho kev ua tau zoo thiab kev paub ntawm cov neeg siv
Cov neeg ua npuas ncauj kuj tuaj yeem hloov kho cov khoom rheological ntawm cov kua, ua rau cov khoom siv yooj yim dua rau kev thov, tshuaj tsuag, lossis txheej txheem, thaum tib lub sijhawm txhawb kev hnov qab. Piv txwv li, nyob rau hauv cov khoom xws li tshuaj zawv plaub hau los yog xab npum ntxuav tes, nplua nuj thiab zoo -textured ua npuas ncauj evokes lub siab ntawm kev nplij siab thiab khoom kim heev rau cov neeg siv; Zoo sib xws, hauv cov khoom ci lossis dej haus, qhov zoo ntawm cov npuas dej ncaj qha cuam tshuam rau ob qho tib si qhov ncauj thiab qhov muag pom. Los ntawm precisely tswj cov hom thiab concentration ntawm tus neeg sawv cev foaming siv, manufacturers muaj peev xwm ua tiav cov kev cai ntawm lub npuas npuas loj, ntom, thiab stability.
