Foaming agents yog cov tshuaj muaj peev xwm inducing npuas tsim thiab stabilizing ua npuas ncauj nyob rau hauv ib tug kua nruab nrab; lawv feem ntau siv nyob rau hauv ob qho tib si industrial manufacturing thiab cov khoom siv niaj hnub. Raws li lawv lub hauv paus chiv keeb thiab tshuaj muaj pes tsawg leeg, cov tshuaj foaming tuaj yeem muab faib ua ob hom: natural foaming agents thiab synthetic foaming agents.
Txhim khu kev ruaj ntseg
Feem ntau, foaming agents tsim ib zaj duab xis molecular ntawm qhov sib cuam tshuam ntawm cov kua thiab gaseous theem, yog li ua rau npuas kom muaj nyob ruaj khov. Tsis tas li ntawd, qee cov neeg ua npuas dej tuaj yeem txuas ntxiv lub neej ntawm cov npuas dej, ua rau nws ruaj khov thiab ruaj khov.
Muaj Kev Ua Haujlwm Nto
Feem ntau ntawm cov foaming agents nthuav tawm cov dej num saum npoo; lawv muaj peev xwm tsim tau ib zaj duab xis ntawm cov kua dej thiab txo qhov nro ntawm qhov chaw, uas pab txhawb kev tsim cov npuas. Cov yam ntxwv no yog lub luag haujlwm tseem ceeb uas cov neeg ua npuas dej ua si hauv cov khoom xws li tshuaj ntxuav tes, tshuaj zawv plaub hau, thiab cov khoom siv zoo sib xws.
Yooj yim ntawm Dispersion thiab Dissolution
Cov neeg ua npuas dej feem ntau sib xyaw nrog cov kev daws teeb meem - xws li dej - yam tsis muaj clumping lossis sib sau ua ke. Nyob rau hauv cov kua nruab nrab, cov neeg ua hauj lwm no qhia tau hais tias zoo heev dispersibility thiab solubility, ua rau lawv yooj yim absorbed thiab siv.
