Cellulose ether yog qhov tseem ceeb polymer cov khoom siv dav hauv lub tsev thiab kev tsim kho. Nws yog hom polymer compound tau los ntawm kev hloov tshuaj lom neeg ntawm cov cellulose ntuj. Nws muaj cov dej zoo solubility, thickening, dej tuav thiab ua yeeb yaj kiab-ua yeeb yam khoom.
1. Thickener
Hauv cov ntaub ntawv hauv tsev, cov neeg ua haujlwm hauv cellulose feem ntau siv raws li cov tuab. Nws tuaj yeem ua kom zoo ua rau cov viscosity ntawm cov ntaub ntawv thiab txhim kho kev ua haujlwm ntawm cov ntaub ntawv. Piv txwv li, ntxiv cellulose cellulose ether rau xis cug cug thiab plaster tuaj yeem nce nws linency thiab ua kev tsim kho kom yooj yim dua. Nyob rau tib lub sijhawm, cov nyhuv tuab ntawm cellulose ether tuaj yeem kuj tuaj yeem tiv thaiv cov ntaub ntawv ntawm sagging thaum lub sijhawm kev tsim kho.
2. Dej tuav tus neeg sawv cev
Cellulose ether muaj cov khoom siv zoo thiab tuaj yeem txo qis dej poob. Hauv cov ntawv tso cai, ntxiv ether ether tuaj yeem txo cov dej ntws thiab ncua sij hawm lub sijhawm, yog li txhim kho lub sijhawm thiab lub sijhawm txhim kho lub zog thiab kav ntev ntawm cov khoom siv. Nyob rau hauv cov nplais nplaum, cov dej-khaws cov nyhuv ntawm cellulose ether tuaj yeem ua kom cov vuas tsis poob thaum lub sij hawm cov txheej txheem sib raug zoo thiab txhim kho lub zog bonding.
3. Roj hlau
Cov neeg hais kom lwm tus neeg muaj cai kuj tseem tuaj yeem siv los ua cov roj nplua nyeem. Ntxiv cov cellulose ether rau cov pob zeb ua tau zoo tuaj yeem txhim kho fluidity thiab lub cev muaj zog ntawm cov pob zeb ua, txo cov kev tiv thaiv, thiab txo kev tsim kho kev tsim kho. Tsis tas li ntawd, lubricating nyhuv ntawm cellulose ether tuaj yeem tuaj yeem txo cov raj xa dej thaum ua haujlwm tso tawm thiab txuas lub neej pabcuam.
4. Los tiv thaiv tus neeg sawv cev
Cellulose ether tseem muaj kev tawm tsam cov nyhuv hauv cov ntaub ntawv hauv tsev. Ntxiv cellulose ether rau gypsum cov khoom tuaj yeem txhim kho qhov tawg tsis kam ntawm gypsum thiab tiv thaiv cov kab nrib pleb los ntawm kev ua kom qhuav. Nyob rau hauv tus kheej-triming pem teb cov ntaub ntawv, cov neeg hais txog cellulose tuaj yeem txhim kho qhov hloov pauv ntawm cov khoom siv, txo cov kev ntxhov siab hnyav, thiab kev tiv thaiv hauv av tawg.
5. Binder
Cellulose ether tseem ua lub luag haujlwm tseem ceeb hauv kev ua raws cov ntaub ntawv xws li cov kua nplaum thiab cov hmoov ua kom tawv. Nws txhim kho cov khoom siv daim ntawv sib khi lus, muab nws zoo adhesion ntawm ntau hom substrates. Nyob rau tib lub sijhawm, cellulose ether tuaj yeem txhim kho cov dej tsis kam thiab huab cua tsis kam ntawm cov khoom, txhim kho kev tsim kho thiab kav ntev.
6. Kev ncua tawm thiab dispersing cov neeg sawv cev
Cov neeg muaj kev hais ua neeg raug siv tau siv raws li kev ncua thiab dispersing cov neeg sawv cev hauv architectural photings. Nws tuaj yeem tiv thaiv cov nag lossis cov fillers thiab xyuas kom muaj kev sib txuam thiab kev ruaj ntseg ntawm cov xim. Ib qho ntxiv, cellulose ether kuj tseem tuaj yeem txhim kho kev tsim kho kev tsim kho ntawm kev ua yeeb yam, ua cov txheej txheej txheej thiab cov npoo du.
7. Siv cug.
Nyob rau hauv kev tsim kho neeg nplua nuj, cov cellulose muaj cov neeg hais tias yog siv li thickeners, dej tuav cov neeg sawv cev thiab cov ntxiv kom txhim kho kev ua haujlwm. Nws tuaj yeem txhim kho cov dej tshem tawm, txuas lub sijhawm qhib thiab muaj zog txo los ntawm kev tshuaj khib nyiab thaum lub sijhawm kev tsim kho. Cellulose ether kuj tseem tuaj yeem txhim kho lub zog ua hauj lwm ntawm kev sib xyaw ua ke, ua kom tau yooj yim mus kis thiab du lub cug, txhim kho kev tsim kho thiab ua tau zoo.
8. Gypsum-based cov ntaub ntawv
Hauv Gypsum-based cov ntaub ntawv, cov neeg hais txog cellulose feem ntau yog siv los txhim kho cov dej khaws cia thiab kev tsim kho cov khoom siv. Nws tuaj yeem tiv thaiv cov kab nrib pleb hauv gypsum cov khoom thaum lub txheej txheem ziab thiab txhim kho lub zog thiab ua kom muaj zog ntawm gypsum. Cov cellulose hais tias cov neeg muaj kev pab thiab ua haujlwm ntawm Gypsum, ua cov khoom lag luam gypsum, ua rau cov qauv gypsum yooj yim dua thiab hloov thaum lub sijhawm tsim kho.
9. Kev ua tus kheej theem
Nyob rau hauv tus kheej-theem cov ntaub ntawv hauv pem teb, ethodose ether yog siv los txhawm rau txhim kho kom zoo nkauj thiab kev ua haujlwm ntawm tus kheej ntawm cov khoom. Nws tso cai rau cov khoom hauv pem teb kom kis tau sai sai thaum lub sijhawm ua kom du, thaum txhim kho cov khoom kom tsis txhob muaj zog, thaum lub zog ntawm cov khoom los tiv thaiv kev tawg thiab xuab zeb hauv av.
10. Pobzeb Adhesive
Cov neeg hais kom lwm tus neeg muaj kev hais ua ke yog siv rau hauv cov pob zeb pobzeb ua kom txuag tau cov dej khaws cia thiab ua kom lub zog ntawm cov nplaum. Nws tuaj yeem tiv thaiv cov vuas los ntawm poob dej tau nrawm thaum lub sijhawm sib raug zoo thiab xyuas kom cov vuas uas yog cov vuas. Nyob rau tib lub sijhawm, cellulose ether tuaj yeem txhim kho kev yoog raws kev yoog raws li cov nplaum, ua kom cov vuas tsis tshua yuav poob thiab tawg thaum siv.
Cov neeg muaj neeg ua haujlwm hauv cellulose muaj ntau cov kev siv hauv lub tsev thiab chaw tsim chaw. Raws li thickeners, dej tuav cov neeg sawv cev, tshuaj tiv thaiv kab nrib pleb, cov neeg sawv cev, cov neeg sawv cev cellulis, cov ntaub ntawv tsim kho hauv tsev kawm ntawv muaj kev ua haujlwm zoo thiab cov khoom siv tau zoo. Nrog kev tsim kho cov thev naus laus zis ntawm kev tsim kho cov kev siv thev naus laus zis, kev thov kev pab ntawm cellulose muaj kev hais kom ua lub tsev thiab kev tsim kho yuav yog dav.
