Kev sivDefoamers(los yog antifoams) tau dhau los ua neeg nyiam nyob hauv kev lag luam papermaking. Cov tshuaj tiv thaiv cheem no pab kom tshem tawm npaus, uas tuaj yeem yog qhov teeb meem loj hauv cov txheej txheem papermakaking. Hauv tsab xov xwm no, peb yuav tshawb txog qhov tseem ceeb ntawm kev tiv thaiv cov ntawv tsim khoom lag luam thiab yuav ua li cas thiaj ua tau kev ua tau zoo thiab zoo.
Dab tsi yog defoamer lossis antifoam?
Ib tug defoamer lossis antifoam yog cov tshuaj lom neeg ntxiv uas siv los txo lossis tshem tawm npuas dej hauv cov txheej txheem kev lag luam. Hauv cov ntawv tsim, ua npuas ncauj tau tsim tau thaum lub sijhawm pulping, uas tuaj yeem ua rau ntau yam teeb meem. Cov teeb meem no tuaj yeem suav nrog kev txo qis hauv cov ntawv zoo, txo cov khoom siv tau ntau, thiab cov nqi nce.
Yuav ua li cas defroamers ua haujlwm
Defoamers ua haujlwm los ntawm Destabilizing Ua npuas ncauj npuas, ua rau lawv tawg thiab vau. Cov txheej txheem no tau ua tiav los ntawm kev sib ntxiv ntawm defoaming tus neeg sawv cev, uas txo cov nro ntawm cov kua thiab pab ua kom tawg npuas npuas. Defoamers tuaj yeem ntxiv ntawm ntau theem ntawm cov txheej txheem papermakaking, suav nrog cov pulping, tshuaj dawb, thiab txheej theem.
Cov txiaj ntsig ntawm defoamers hauv cov ntawv tsim khoom
Kev siv ntawm defoamers hauv cov ntawv tsim khoom tuaj yeem muab cov txiaj ntsig ntau, suav nrog:
Txhim kho kom zoo: Defoamers tuaj yeem pab txo lossis tshem tawm cov npaus, uas tuaj yeem ua rau txo qis hauv cov ntawv zoo. Los ntawm kev siv defoamers, cov ntawv manufacturers tuaj yeem tsim cov ntawv siab dua nrog tsawg dua qhov tsis xws luag thiab tsis txaus ntseeg.
Muaj zog ntxiv: Ua npuas dej tseem tuaj yeem ua teeb meem nrog kev ua haujlwm tau zoo, raws li nws tuaj yeem ua kom qeeb kev tsim kho kom qeeb thiab txo kev tawm tsam. Los ntawm kev tshem tawm cov ua npuas ncauj, cov ntawv tsim khoom lag luam tuaj yeem txhim kho cov kev ua tau zoo thiab nce kev cuam tshuam.
Txo Nqi: Ua npuas ncauj tuaj yeem ua rau cov nqi nce ntxiv, vim tias nws yuav ua rau cov khoom siv nrog cov khoom siv thiab xav tau cov peev txheej ntxiv los daws. Los ntawm kev siv defoamers, cov ntawv tuam txhab tuaj yeem txo cov nqi cuam tshuam nrog cov teeb meem ua npuas ncauj.
Hom kev tiv thaiv
Muaj ntau ntau hom kev tiv thaiv uas tuaj yeem siv rau hauv cov ntawv tsim khoom, suav nrog:
Silicone-based defoamers: Cov neeg tiv thaiv no yog siv tau hauv cov ntawv tsim khoom, raws li lawv tau siv tau ntau dua ntawm kev txo cov npuas dej thiab muaj ntau yam ntawm cov pa hluav taws xob.
Ntxhia roj-raws defoamers: cov neeg tiv thaiv no feem ntau siv hauv cov ntawv tsim khoom, tab sis lawv tuaj yeem siv nyiaj ntau dua li Silicone-based defoamers.
Cov zaub roj-bathers: Cov neeg tiv thaiv no tau ua nrov ntau hauv cov ntawv, raws li lawv yog tus phooj ywg ib puag ncig thiab tuaj yeem ua kom tau zoo rau ua npuas ncauj.
Antifoamsyog qhov tseem ceeb hauv cov ntawv tsim kev ua haujlwm. Los ntawm kev txo los yog tshem tawm cov ua npuas ncauj lossis cov ntaub ntawv tsim khoom tuaj yeem tsim cov ntawv ntau dua, nce ntau ntau ntau ntau yam khoom. Muaj ntau hom kev tiv thaiv uas tuaj yeem siv, suav nrog cov roj silicone-raws li, cov roj av ntxhia-raws li, thiab zaub roj-raws li defoamers. Los ntawm kev xaiv defoamer tsim nyog rau lawv cov txheej txheem, cov ntawv tuam txhab tuaj yeem kho lawv txoj haujlwm thiab ua tiav kev vam meej ntau dua.
