Silicone Defoamersyog muab tau los ntawm silicone polymers thiab ua hauj lwm los ntawm destabilizing tus npaus qauv thiab tiv thaiv nws tsim. Silicone antifoams feem ntau stabilized li dej-raws li emulsions uas muaj zog ntawm tsawg concentrations, tshuaj inert, thiab muaj peev xwm mus sai sai diffuse mus rau hauv lub ua npuas ncauj zaj duab xis. Vim yog cov yam ntxwv no, nws yog nrov heev ntawm cov neeg xaiv. Nws tau dav siv nyob rau hauv ntau daim ntawv thov kev lag luam los pab txhim kho ua npuas ncauj tswj hauv kev ua tshuaj.
1. Kev ua zaub mov
Silicone defoamers tau dav siv hauv kev sib cuag cov zaub mov ncaj qha lossis tsis ncaj rau txhua theem ntawm cov txheej txheem kev lag luam. Los ntawm cov chaw tsim khoom loj thiab cov khw noj mov mus rau kev ua noj hauv tsev, ntim khoom noj thiab cov ntawv lo, silicone tuaj yeem pom nyob txhua qhov chaw. Silicone muaj qhov zoo ntawm kev siv yooj yim, kev ua haujlwm nyab xeeb, tsis muaj ntxhiab tsw, thiab tsis cuam tshuam rau cov khoom noj khoom haus, muab qhov zoo sib xws hauv kev ua tiav ntau yam kev xav tau ntawm kev ua zaub mov. Lawv yog siv nyob rau hauv ntau yam khoom noj thiab dej haus daim ntaub ntawv rau defoam los yog tshem tawm cov npuas dej uas twb muaj lawm thaum lub sij hawm tsim khoom.
Foaming teeb meem hauv kev ua zaub mov thiab dej haus tuaj yeem cuam tshuam rau kev ua haujlwm, tsim khoom thiab nqi. Silicone antifoams, los yog defoamers, yog siv los ua kev pab cuam thiab tsim kom muaj kev nyab xeeb thiab zoo txo cov teeb meem ua npuas ncauj raws li ntau yam kev mob tshwm sim hauv kev ua zaub mov thiab dej haus. Txawm hais tias ntxiv purely hauv cov kua los yog hmoov, los yog tov rau hauv lwm cov tebchaw los yog emulsions, silicone defoamer yog zoo dua li cov organic defoamer.
① Kev ua zaub mov: Nws tuaj yeem cuam tshuam zoo hauv kev ua zaub mov. Nws feem ntau yog siv rau hauv kev ua cov khoom noj uas muaj dej-soluble. Nws muaj kev ua haujlwm ruaj khov thiab zoo defoaming nyhuv.
② Qab Zib kev lag luam: Ua npuas ncauj yuav raug tsim thaum lub sij hawm zib mu qab zib txheej txheem, thiab defoaming cov neeg sawv cev yog xav tau rau defoaming.
③ Fermentation kev lag luam: Cov kua txiv hmab txiv ntoo yuav tsim cov roj thiab ua npuas ncauj thaum lub sij hawm fermentation, uas yuav cuam tshuam rau ib txwm fermentation. Defoaming cov neeg ua haujlwm tuaj yeem ua tau zoo defoam thiab xyuas kom zoo ntawm cov cawv ntau lawm.
2. Textiles thiab tawv
Hauv cov txheej txheem textile, textile mills them tshwj xeeb rau kev ua haujlwm ntawm cov neeg ua haujlwm defoaming. Kev lag luam textile muaj cov kev cai nruj heev rau defoaming cov neeg ua haujlwm, xws li cov viscosity yuav tsum tsis txhob siab dhau, nws yog ib qho yooj yim mus use, qhov sib ntxiv yog ib qho yooj yim los tswj, nws yog yig, tsis tshua muaj nqi, thiab nws defoaming yog ceev. Cov nyhuv defoaming yog ntev-ntev. Zoo dispersion, tsis muaj xim, tsis muaj silicon me ntsis, muaj kev nyab xeeb thiab tsis muaj tshuaj lom, ua tau raws li kev tiv thaiv ib puag ncig, thiab lwm yam.
Lub tuam txhab luam ntawv thiab dyeing auxiliary tuam txhab tsim ntau yam khoom siv tus kheej tsim thiab xav tau cov neeg ua haujlwm defoaming nrog cov yam ntxwv hauv qab no: yooj yim rau dilute thiab compound, muaj lub neej ntev txee, thiab cov nqi zoo. Peb cov silicone defoamer daws qhov teeb meem ntawm kev sib xyaw nrog cov pab cuam thiab muab kev txhawb nqa.
Cov tub lag luam ntawm dyeing chemical raw cov ntaub ntawv, feem ntau ntawm cov neeg siv mature, xav tau defoaming cov neeg ua haujlwm uas raug nqi, muaj cov khoom ruaj khov, thiab muab kev txhawb nqa.
Kev xyaum tau ua pov thawj tias defoaming agents rau textile printing thiab dyeing yuav tsum muaj: sai defoaming, ntev-ntev ua npuas ncauj suppression, siab nqi-zoo; zoo dispersion, kub tsis kam, acid thiab alkali tsis kam, electrolyte kuj, shear kuj, thiab compatibility nrog ntau yam dyeing agents; nyab xeeb, tsis muaj tshuaj lom, ua tau raws li ib puag ncig; ruaj khov zoo, tsim nyog viscosity thiab concentration, yooj yim rau siv thiab dilute; muab kev pabcuam raws sijhawm thiab ua haujlwm tau zoo.
3. Pulp thiab ntawv
Raws li hom tshiab ntawm defoaming tus neeg saib xyuas, nquag siv silicone defoaming tus neeg saib xyuas tau txais kev saib xyuas thoob plaws hauv kev lag luam papermaking. Lub hauv paus ntsiab lus ntawm defoaming yog tias thaum tus neeg sawv cev defoaming nrog qhov tsis tshua muaj qhov nro nkag mus rau hauv cov yeeb yaj kiab ua npuas, nws rhuav tshem cov yeeb yaj kiab ua npuas. Mechanical sib npaug tuaj yeem ua tiav kom ua tiav ua npuas ncauj tawg thiab tswj.
Silicone defoaming cov neeg ua haujlwm tau dhau los ua cov khoom siv tsis tseem ceeb thoob plaws ntau qhov kev lag luam, muab cov kev tswj xyuas ua npuas dej zoo uas pab txhawb kev txhim kho kev ua tau zoo, cov khoom zoo, thiab kev tswj xyuas.
