Gypsum (Caso ange · 2thoj siv thiab siv cov khoom siv, xws li cov khoom siv hluav taws xob, thiab lwm yam tsis txaus ntseeg, thiab txo qis dua tom qab nqus dej. Cov teeb meem no txwv tsis pub siv cov ntawv thov thiab kev pabcuam lub neej ntawm Gypsum cov khoom lag luam. Txhawm rau txhim kho cov kev ua tsis txaus no, cellulose cov ntxiv feem ntau ntxiv rau cov khoom lag luam gypsum. Qhov kev sib ntxiv ntawm cellulose tuaj yeem txhim kho kev ua tau zoo ntawm gypsum, yog li txhim kho lawv kev ua lag luam kev sib tw.
1. Txhim Kho Kev Ua Haujlwm
Rheology Ua Kom Zoo
Gypsum xav tau cov fellity zoo thiab cov haujlwm ua haujlwm thaum siv. Cellulose additives tuaj yeem txhim kho cov khoom siv hluav taws xob rheological ntawm gypsum slurry. Cellulose nthuav tawm hauv dej los ua qhov kev daws teeb meem siab, yog li ncua kev ua kom zoo nkauj ntawm cov gypsum thiab muab cov slurry kev tsim kho thiab lub sijhawm ua haujlwm zoo dua. Cov xeeb ceem no yog qhov tshwj xeeb tshaj yog rau Gypsum txau thiab nchuav cov txheej txheem ntawm cov slurry, zam kev ua txhaum thiab los ntshav, thiab txhim kho kev tsim kho zoo.
Txhim Kho Dej Tuav
Cellulose tuaj yeem txhim kho cov dej khaws cia ntawm gypsum slurry. Gypsum yuav tsum muaj qee qhov dej kom ua tiav cov txheej txheem tawv thaum lub sijhawm cov txheej txheem hydration. Cov dej zoo khaws cia tuaj yeem tiv thaiv kom dej los ntawm kev ua kom muaj dej nyuaj heev thaum cov txheej txheem hayuring, yog li ua kom muaj zog txaus ntawm cov gypsum thiab txhim kho nws lub zog kawg. Cellulose ua cov tshuaj tiv thaiv kab mob uas tau faib dej nyob ib ncig ntawm cov khoom ntawm cov ceg hlau, tiv thaiv kev tiv thaiv tsis zoo los ntawm kev ua kom sai.
Los tiv thaiv muaj peev xwm
Hauv Gypsum Txheej Kev Siv, Sag Yeem yog qhov taw qhia tseem ceeb. Qhov kev sib ntxiv ntawm cellulose tuaj yeem nce viscsum slurry, tso cai rau qhov ua kom zoo dua qub thaum lub ntiajteb ua haujlwm, thiab ua kom muaj kev sib luag thiab tuab sib xws ntawm txheej.
2. Txhim khu cov khoom siv kho tshuab
Txhim kho cov tawg
Cellulose fibers tuaj yeem txhim kho qhov tawg tsis kam ntawm gypsum-based cov ntaub ntawv. Gypsum cov khoom yuav txiav tawm hauv cov ntim thaum lub sij hawm ua kom tawv nqaij tawv, ua rau muaj kev ntxhov siab sab hauv thiab yooj yim ntawm cov kab nrib pleb. Cellulose fibers tuaj yeem tsim ib qho kev sib tw ntawm cov qauv sib tw hauv Gypsum Matrix, tabkaum kev nthuav dav ntawm cov nrib pleb, yog li kev txhim kho cov khoom tawg tsis kam. Qhov no yog lub luag haujlwm tseem ceeb hauv kev txhim kho lub neej pabcuam ntawm Gypsum Cam, Hniav plaster thiab lwm yam khoom.
Ua kom nce siab ntxiv
Cellulose Fibulose tuaj yeem txhim kho cov khoom muaj zog ntawm gypsum thiab txo cov brittleness. Cov khoom siv gypsum nws tus kheej yog nkig thiab nquag tawg thaum cuam tshuam lossis khoov. Qhov kev sib ntxiv ntawm cellulose fibers tuaj yeem muab cov khoom sib ntxiv, tso cai rau cov khoom kom muaj kev ntxhov siab zoo dua thaum raug teeb meem thiab txo qhov tsis muaj tseeb. Cov xeeb ceem no yog qhov tshwj xeeb tshaj plaws hauv Gypsum Board thiab Gypsum cov khoom zoo nkauj, vim tias cov khoom no tuaj yeem cuam tshuam los ntawm cov yuam kev sab nraud thaum siv.
Txhim Kho Dabtsi Yog Kho Lub Zog
Cellulose Fibulose kuj tseem muaj kev cuam tshuam tseem ceeb rau ntawm FLEXURAL lub zog ntawm Gypsum cov khoom lag luam. Cellulose Fibers tuaj yeem tsim txoj kev txhawb nqa cov qauv hauv Gypsum matrix thiab nce nws lub zog yooj yooj yim. Qhov no yog tau txais txiaj ntsig tshwj xeeb rau cov khoom siv gypsum, raws li cov khoom muaj zog ntxiv nce lub peev xwm ntawm lub rooj tsavxwm.
3. Txhim kho qhov ruaj khov
Kev Txhim Kho Cov Dej Tsis kam
Qhov sib ntxiv ntawm cellulose tuaj yeem txhim kho cov dej tsis kam ntawm gypsum-based cov ntaub ntawv. Gypsum cov ntaub ntawv yuav muag tom qab dej thiab lawv lub zog yuav txo qis, yog li cuam tshuam lawv lub neej pabcuam. Cellulose tuaj yeem tsim zaj duab xis tiv thaiv nyob rau saum npoo ntawm cov khoom los txo cov kev nkag mus ntawm noo noo, yog li kev txhim kho cov khoom siv dej tsis kam. Txhim kho cov dej tsis kam tuaj yeem ua tau zoo rau lub neej ntawm Gypsum cov khoom lag luam hauv cov chaw muaj kev puas tsuaj tshwm sim los ntawm kev nqus dej thiab ua kom tawg.
Tiv thaiv kab mob sib cais
Cellulose tiv thaiv soobtion thaum lub chaw tsim khoom ntawm gypsum-based cov ntaub ntawv. Cellulose tuaj yeem siv cov nplais uas muaj peev xwm tiv thaiv cov nplais, tiv thaiv cov plaub hau ntawm lub qab nkoj thiab lub teeb ntawm cov khoom sib txawv ntawm cov khoom siv. Qhov no yog qhov tseem ceeb tshaj plaws hauv kev txhim kho qhov zoo thiab muaj zog ntawm cov khoom siv plaster.
Khov thiab thaw tsis kam
Qhov kev sib ntxiv ntawm cellulose kuj tseem tuaj yeem txhim kho lub khov-thaw kev tawm tsam ntawm gypsum cov ntaub ntawv. Nyob rau hauv cov cheeb tsam txias, gypsum cov khoom yuav yauv mus rov qab khov-thaw mus taw tes, ua rau muaj kev puas tsuaj rau cov khoom. Cellulose tuaj yeem txo cov kev ntxhov siab sab hauv lub sijhawm thaum lub sijhawm khov thiab kev thau kom khov thiab txhim kho lub durability ntawm cov khoom siv los ntawm nws cov dej khaws cia thiab txhawb cov txiaj ntsig.
4. Kev tiv thaiv ib puag ncig thiab kev ruaj khov
Hnub rov kho tau
Cellulose yog lub ntuj qub, txuas ntxiv tau muab rho tawm los ntawm cov nroj tsuag uas yog ib puag ncig phooj ywg thiab muaj kev cia siab. Siv cellulose los ua cov khoom ntxiv rau gypsum-based cov ntaub ntawv tsis tsuas yog ntsib ib puag ncig ib puag ncig, tab sis kuj txo qis ntawm cov khoom siv tsis-tshiab.
Biodegradity
Cellulose muaj zoo biodegrentability, uas txhais tau tias tom qab cov khoom lag luam gypsum tau muab pov tseg, cellulose tuaj yeem ua rau ib puag ncig ib puag ncig. Qhov no tau pom tseeb ib puag ncig zoo piv nrog qee cov hluavtaws hluavtaws.
5. Cov Ntawv Thov Tshwj Xeeb
Haum rau ntau hom gypsum
Qhov khoom siv ntau yam ntawm cellulose ua nws haum rau siv nyob rau hauv ntau hom ntawm cov khoom lag luam gypsum, suav nrog cov flatwall, zoo nkauj plaster, thiab ntau dua. Txawv ntau hom cellulose derivatives (xws li hydroxypropyl cellulose, carboxymethyl cellulose, thiab lwm yam yuav tsum tau ua tiav cov txiaj ntsig zoo tshaj plaws.
Haum rau cov kev sib txawv
Cellulose additives qhia tau zoo yoog raws li kev tsim kho sib txawv. Piv txwv li, cellulose tseem tuaj yeem txhim kho kev tsim kho kev tsim kho ntawm Gypsum slurry hauv ib puag ncig siab lossis qis dua. Cov cuab yeej no tso cai rau gypsum-based khoom lag luam los nthuav tawm kev ua tau ruaj khov nyob rau ntau yam ntawm huab cua huab cua.
Kev siv cov cellulose hauv cov khoom lag luam gypsum tau txhim kho kom zoo dua qub ntawm gypsum cov khoom siv los ntawm kev txhim kho cov khoom siv ua haujlwm, txhim kho lub zog ua kom muaj txiaj ntsig thiab muab cov txiaj ntsig ib puag ncig. Cov kev hloov pauv hloov kho no pab tau Gypsum cov khoom kom ua tau raws li kev tsim kho tshiab thiab kev kho kom zoo nkauj thiab nthuav lawv cov ntawv thov. Nrog rau kev txhim kho cov ntaub ntawv siv thev naus laus zis, kev thov cov khoom lag luam hauv gypsum thiab hauv siab ntxiv los muab cov kev daws teeb meem zoo, txuas ntxiv ua kom muaj kev ua kom zoo rau kev tsim kho.
