HLB value range: The HLB value of water in oil emulsifiers is generally between 8-18. Qhov siab dua HLB tus nqi, qhov muaj zog ntawm hydrophilicity ntawm emulsifier, uas yog qhov tsim nyog rau kev tsim cov dej hauv cov roj emulsion system. Piv txwv li, emulsifier nrog HLB tus nqi ntawm 15 tuaj yeem faib cov roj hauv dej kom zoo los tsim cov tshuaj pleev kom ruaj khov raws li qhov tsim nyog cov roj-dej piv thiab cov xwm txheej.
Hais txog kev hnov qab ntawm daim tawv nqaij (hauv cov tshuaj pleev ib ce): Cov khoom tsim nrog dej hauv cov roj emulsifiers feem ntau muaj qhov kev xav ntawm daim tawv nqaij. Piv nrog rau cov dej hauv cov roj emulsion, nws yuav tsis coj greasy zoo rau ntawm daim tawv nqaij, thiab nws yooj yim dua rau kis ntawm daim tawv nqaij tom qab thov. Nws yog qhov tsim nyog rau qee cov khoom tu tawv nqaij, xws li tshuaj pleev, gel thiab lwm yam khoom siv rau lub caij ntuj sov.
Hais txog kev ua haujlwm, kev ua haujlwm ntawm cov dej hauv cov roj system yog qhov yooj yim. Thaum lub sij hawm kev npaj, kev sib tov thiab emulsification ntawm ob theem tuaj yeem ua tiav tau yooj yim yam tsis tas yuav muaj cov txheej txheem ntau dhau thiab cov khoom siv. Piv txwv li, nyob rau hauv lub chaw soj nstuam sim los yog kev lag luam loj-loj ntau lawm, roj nyob rau hauv cov tshuaj pleev ib ce tuaj yeem tau los ntawm kev sib xyaw thiab homogenizing roj theem, dej theem thiab emulsifier raws li qee cov kauj ruam.
