Kev siv ntawm gypsum-based cov khoom lag luam yog ua kom nrov dua hauv kev tsim kho. Gypsum yog ib qho khoom siv ntuj siv nyob rau hauv kev tsim cov ntaub ntawv hauv tsev. Txawm li cas los xij, cov khoom lag luam gypsum yog nquag mus rau qhov tsis xws luag tshwm sim los ntawm kev sib kis thiab qhov sib txuas. Yog li, cov khoom plaster yuav tsum yog degreased kom tshem tawm cov kev cuam tshuam deg thiab txhim kho lawv cov tsos.
HydroxyPropyyl methylcellulose (HPMC) yog ib qho siv tau dav ntxiv hauv kev tsim kho kev tsim kho. Nws yog cov neeg nonionic cellulose ether uas yog yooj yim soluble hauv dej thiab muaj cov yeeb yaj kiab zoo tshaj plaws. HPMC muaj ntau cov kev siv, suav nrog ua cov tuab dua, cov nplaum thiab dej khaws cia tus neeg sawv cev. Vim nws cov kev ua tau zoo tshaj plaws, HPMC tau siv dav hauv ntau qhov kev lag luam, suav nrog kev tsim kho, chaw muag tshuaj thiab khoom noj khoom haus.
Low-tshauv, siab-purity hpmc rau gypsum degreasing:
Tsawg av tshauv siab Purity HPMC yog ib daim ntawv advanced ntawm HPMC thiab tau siv dav hauv kev tsim cov khoom lag luam. Vim nws cov ntoo tshauv qis thiab muaj kev huv, nws yog qhov kev xaiv zoo rau kev xaiv Gypsum. Cov Tshauv tsis muaj siab purity hpmc yog tsim los ntawm cellulose zoo los ntawm ntoo pulp. Kev tsim qauv ntawm xws HPMC cuam tshuam ntau qib, suav nrog kev ua kom huv si, pom kev, thiab ziab. Tus txheej txheem no ua kom cov khoom kawg yog qhov ua tau zoo tshaj plaws, nrog cov hmoov tshauv muaj tsawg dua 1%.
Lub hauv qab tshauv muaj cov ntaub ntawv tshauv ntawm hom HPMC no ua rau nws zoo tagnrho rau kev ua haujlwm Gypsum. Qhov muaj cov hmoov tshauv hauv HPMC tuaj yeem ua rau staining lossis discoloration ntawm cov plaster saum npoo. Yog li ntawd, qis-tshauv HPMC yuav tsum tau siv thaum hais daws kom tsis txhob muaj qhov tsis xws luag saum npoo.
Cov av tshauv qis siab purity HPMC, ntxiv rau nws cov ntsiab lus tshauv tsawg, kuj muaj cov kev coj dawb huv. Txoj kev ua kom tiav qib kev ua siab dawb uas HPMC tsis muaj ib qho kev cuam tshuam uas muaj peev xwm ua tsis tau zoo ntawm cov khoom lag luam gypsum. Lub siab ua siab dawb ntawm hom HPMC no ua rau nws zoo tagnrho rau cov ntawv thov uas cov khoom kawg zoo yog qhov tseem ceeb.
Qhov zoo ntawm kev siv cov qes qis-tshauv, high-purity hpmc rau gypsum degreasing:
1. Txhim kho cov tsos saum toj: Siv cov qes qis-tshauv, siab-purity hpmc thaum lub ntsej muag degrimities thiab txhim kho cov tsos ntawm gypsum-based khoom.
2. Txhim Kho Kev Ua Tau Zoo: Ntxiv qis-av, siab-purity HPMC mus rau cov khoom lag luam gypsum tau txhim kho lawv cov peev txheej, xws li lub zog ua kom muaj zog thiab ua kom muaj zog.
3. Txo cov kev cuam tshuam ib puag ncig: kev siv qis-tshauv, siab dua hpmc nyob rau hauv kev tsim cov khoom lag luam ib puag ncig los ntawm kev txwv cov khib nyiab.
4. Tus nqi-ua tau zoo: kev siv qis-tshauv, siab purity HPMC hauv kev tsim kho yog nqi tsis xws luag thiab txhim kho qhov zoo ntawm cov khoom kawg.
Cov Tshauv Heev Kev Purity HPMC yog cov khoom lag luam tshiab uas tau hloov kho cov kev lag luam tsim kev lag luam. Nws siv hauv kev tsim cov gypsum-raws cov khoom tseem txhim kho qhov zoo thiab pom ntawm cov khoom no. Cov hmoov tshauv qis thiab muaj kev huv ntawm hom HPMC ua rau nws zoo tagnrho rau kev ua haujlwm Gypsum. Yog li ntawd, kev siv qis-ntoo qis, siab-purity hpmc yog qhov tseem ceeb los ua cov khoom lag luam zoo gypsum-raws li cov khoom lag luam
