Npuas yog ib qho teeb meem tshwm sim nyob rau hauv ntau yam kev lag luam. Lawv tsim tuaj yeem cuam tshuam kev tsim khoom thiab txawm tias cov khoom zoo. Yuav ua li cas kom zoo thiab yooj yim tshem tawm lossis tswj ua npuas ncauj yog ib qho kev txhawj xeeb rau txhua tus neeg tsim khoom. Yog li ntawd, defoamers tau dhau los ua qhov kev daws teeb meem zoo tshaj plaws rau txhua qhov chaw tsim khoom los daws cov teeb meem ua npuas ncauj.
Raws li lub npe qhia, defoamer yog ib qho tshuaj ntxiv uas tshem tawm ua npuas ncauj. Thaum ib qho organosilicone defoamer ntxiv rau lub tshuab ua npuas dej, nws tawg sai sai. Cov molecules surfactant sib haum rau ntawm npuas nto. Thaum cov organosilicone defoamer nce mus txog ib qho concentration, thiab muaj cov molecules txaus surfactant, ib daim ntawv nyias nyias ntawm phab ntsa npuas, txo nws qhov nro thiab ua rau cov roj ntau ntxiv -kua thaj chaw. Qhov no thaum kawg ua rau cov npuas tsis tshua muaj coalesce thiab tawg. Piv nrog rau lwm hom defoamers, organosilicone defoamers muaj cov yam ntxwv hauv qab no: 1. Daim ntawv thov dav: Vim lub insolubility ntawm silicone roj nyob rau hauv ntau yam tshuaj, nws muaj ntau yam kev siv, haum rau ob qho tib si dej thiab roj systems . 2. Tsawg nto nro thiab zoo defoaming efficiency . 3. Zoo thermal stability, usable tshaj qhov kub thiab txias.
4. Kev ruaj ntseg tshuaj zoo; Nrog cov qauv tsim nyog, silicone defoamers tuaj yeem siv rau hauv cov tshuab uas muaj cov kua qaub, alkalis, thiab ntsev. Silicone defoamers muaj qhov zoo tshaj plaws defoaming thiab ua npuas ncauj- cov khoom tiv thaiv, yog cov yam ntxwv ntawm kev siv tsawg, tsis muaj tshuaj lom neeg zoo, thiab muaj peev xwm ua haujlwm tau zoo hauv cov xwm txheej hnyav. Nyob rau hauv xyoo tas los no, lawv tau ntsib txoj kev loj hlob sai, nrog ntau yam tshiab thiab cov qauv tsim tawm tas li kom haum rau qhov sib txawv ntawm daim ntawv thov ib puag ncig, thiab lawv daim ntawv thov tau nthuav dav ntxiv.
