Cov neeg hais daws cellulose yog chav kawm ntawm cov tshuaj sib xyaw ua ke los ntawm cellulose, lub ntuj polymer pom nyob hauv tsob ntoo cell phab ntsa. Cov kev siv cellulos no tau pom cov ntawv thov uas muaj kev tsim kho hauv kev tsim kho, tshwj xeeb hauv kev tshuaj khib thiab cov khoom lag luam gypsum. Lawv txoj kev sib xyaw ua cov khoom siv no ua rau lawv cov yam ntxwv ua tiav.
Tshuaj lom neeg cov khoom ntawm cellulose neeg muaj kev pab
Cov neeg hais txog cellulose yog tsim los ntawm kev kho mob cellulose los hloov nws pawg hydroxyl nrog ether pawg. Qhov kev hloov kho no uas cuam tshuam ntau yam khoom, xws li cov dej solubility, thickening, thiab zaj duab xis-tsim lub peev xwm. Hom kev siv cellulose siv hauv kev tsim kho muaj xws li:
Methylcellulose (MC)
Hydroxyethylcellulose (HEC)
HydroxyPropyyl methylcellulose (HPMC)
Carboxymethyl cellulose (cmc)
Cov pawg cellulose sib txawv txawv hauv lawv cov pab pawg tshwj xeeb, uas cuam tshuam rau lawv solubility, viscosity, thiab cuam tshuam nrog lwm cov hauv cov khoom siv.
Cov txiaj ntsig ua haujlwm nyob rau hauv cug thiab gypsum-based khoom
Dej ceev
Cellulose hais tau hais tias kev txhim kho dej kom tsis txhob muaj lub peev ceev ntawm cov tshuaj khib thiab gypsum-based khoom. Cov cuab yeej no yog qhov tseem ceeb rau cov txheej txheem hydration ntawm cov cement thiab gypsum. Txhim kho cov dej khaws cia kom cov dej uas muaj nyob ntev dua thiab txo qhov kev pheej hmoo ua kom qhuav, uas tuaj yeem ua rau tawg thiab txo lub zog.
Kev ua haujlwm thiab xwm yeem
Qhov kev sib txuas ntawm cov cellulose muaj neeg muaj kev pab cuam txhim kho qhov ua haujlwm ntawm colleg thiab gypsum mixtures. Cov tebchaw no nce viscosity thiab vacuity ntawm cov sib tov, ua rau nws yooj yim dua los lis thiab thov. Kev ua haujlwm tau zoo ua rau kom muaj txiaj ntsig zoo dua, troweling, thiab shaping ntawm cov khoom siv, ua rau cov ntawv thov smoother thiab ntau dua.
Sag Kuj
Hauv cov ntawv qhia ntsug lossis siv nyiaj ntau tshaj, xws li plastering thiab rendering, sagging tuaj yeem yog qhov teeb meem tseem ceeb. Cellulose hais tias kev hais ua ke rau kev sib xyaw, muab cov gel-zoo li kev sib xws thaum ntawm so, uas pab tiv thaiv kom tiv thaiv tsis taus. Raws li kev ntxhov siab los yog shear, cov khoom siv dej ntau dua, tso cai rau daim ntawv thov yooj yim dua. Ib zaug thov, nws rov qab mus rau nws cov gel-zoo li lub xeev, tswj nws txoj haujlwm tsis tau swb.
Bond lub zog
Qhov txuam ntawm cov cellulose cov neeg muaj kev pab txhim kho cov khoom nplaum ntawm cug cug thiab gypsum cov khoom lag luam.

Cov cuab yeej no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov xws li pobzeb cov nplaum thiab sab nraud ua haujlwm.
Teem Sijhawm
Cov neeg hais txog cellulose tuaj yeem cuam tshuam lub sijhawm lub sijhawm tshuaj khib thiab gypsum. Ua raws li cov qauv tshwj xeeb, lawv tuaj yeem nrawm lossis rov teeb cov txheej txheem teeb tsa. Qhov kev tswj hwm no rau lub sijhawm tso cai raws li cov kev cai tshwj xeeb ntawm daim ntawv thov thiab ib puag ncig cov mob, kom ua haujlwm zoo rau kev ua haujlwm thiab kho cov mob.
Txo ntawm shrinkage thiab tawg
Shrinkage thiab cov cracking yog cov teeb meem tshwm sim hauv cov khoom noj thiab cov khoom siv gypsum thiab gypsum raws li kev poob dej thaum lub sijhawm ua kom qhuav. Cellulose hais pab tau kev ua tshuaj tua cov teeb meem no los ntawm kev tswj cov dej noo nyob hauv kev sib xyaw kom ntev dua. Qhov no tswj cov txheej txheem kom qhuav txo qis qhov ntxim nyiam ntawm shrinkage thiab tawg, ua rau muaj cov qauv ruaj khov thiab ruaj khov.
Cuam tshuam rau cov txheej txheem tsim kho
Yooj yim ntawm daim ntawv thov
Kev ua haujlwm tau zoo thiab sib txawv muab los ntawm Cellulose muaj cai ua rau cov txheej txheem thov ntau dua thiab tsis muaj zog ua haujlwm. Cov neeg ua haujlwm tuaj yeem ua tiav cov kab smoother nrog rau kev siv zog tsawg dua, txo lub sijhawm tag nrho thiab tus nqi ntawm kev tsim kho cov phiaj xwm.
Kev Tswj Xyuas Zoo
Qhov kev sib xyaw ua ke nyob rau hauv kev sib xyaw ua ke thiab txhim kho dej kom muaj zog ua haujlwm pab txhawb ua kom zoo dua qub. Cov kev sib xyaw ua kom zoo nkauj ua rau muaj kev pom zoo thiab ntseeg tau tias cov khoom kawg tau raws li cov qauv uas yuav tsum tau ua thiab tshwj xeeb.
Versatility
Cov neeg hais txog cellulose tuaj yeem ua kom cov kev xav tau los ntawm kev kho lawv cov qauv molecular thiab kev xav tau. Cov versatility no tso cai rau customized ua kom haum rau cov kev tsim kho ntau yam, los ntawm plastering thiab rendering rau vile adhesives thiab tus kheej theem sib txuas.
Kev txiav txim siab ib puag ncig thiab kev lag luam
Muaj zog
Raws li cov cellulose muaj kev hais ua los ntawm cov khoom siv nroj tsuag tshiab, lawv siv ua rau cov kev tsim kho kev tsim kho. Lawv muab cov kev hloov kho ib puag ncig rau cov khoom sib ntxiv rau hluavtaws, txo cov hlau ntsuas txhua yam ntawm kev tsim kho.Cost-effectiveness
Thaum cov neeg hais txog cellulose yuav muaj ntxiv rau thawj cov khoom siv thawj zaug, txo kev ua haujlwm thiab kev ua haujlwm tsawg dua hauv lub sijhawm ntev. Enhanced durability thiab txo cov mob durability ua rau kev kho dua tshiab thiab ntev dua-kav ntev, txhais cov nqi txuag tau raws sijhawm.
Cov Ntaub Ntawv Kawm thiab Kev Siv
Plaster thiab rendering
Nyob rau hauv plaster thiab rendering cov ntawv thov, cellulose muaj kev hais ua kom muaj zog, txo sagging, thiab txhim kho nto tiav. Lawv siv cov txiaj ntsig hauv smoother, ntau cov phab ntsa zoo nkauj thiab qab nthab nrog kev txhim kho kom ruaj khov.
Cov nplaum nplaum
Pobzeb Adhesives Tau txiaj ntsig los ntawm kev txhim kho txoj hlua khi zog thiab cov haujlwm ua haujlwm muab los ntawm cellulose muaj kev hais ua. Cov khoom no kom ua kom muaj kev ruaj ntseg tile tso thiab txo qhov kev pheej hmoo ntawm cov vuas loos poob lossis poob sijhawm.
Kev Ntsuas Tus Kheej
Txog kev ua kom tus kheej-ntsuas, cov cellulose muaj kev hais kom muaj kev du, txawm saum npoo los ntawm kev tswj lub viscosity thiab txaus siab ntawm cov khoom sib xyaw. Daim ntawv thov no yog qhov tshwj xeeb tshaj yog rau kev sib txuas hauv flooring, qhov chaw theem deg yog qhov tseem ceeb.
Qhov kev sib txuas ntawm cellulose tsim kev tshuaj khib thiab gypsum-based cov khoom muaj ntau cov txiaj ntsig uas ua haujlwm tau zoo, ua haujlwm, thiab kav dej. Los ntawm kev txhim kho cov dej cia, xwm yeem, nyiaj pov tseg lub zog, thiab kev txo qis qis, cov neeg hais ua ke, cellulose hais pab ua rau cov txiaj ntsig zoo dua. Lawv cov kev cuam tshuam rau cov txheej txheem kev tsim kho, ua ke nrog kev ua haujlwm ib puag ncig thiab kev lag luam zoo, tsis muaj qhov tseem ceeb hauv kev coj ua niaj hnub no. Raws li kev tsim kho kev tsim kho txuas ntxiv mus evolve, lub luag haujlwm ntawm cellulose kev ua kom muaj kev daws teeb meem thiab cov kev daws teeb meem hauv tsev yuav tseem ceeb.
