Cellulose, tseem hu ua hydroxypropsylrcellulose (HPMC), yog ib qho tseem ceeb ntawm Gypsum. Gypsum yog ib phab ntsa siv dav dav thiab cov khoom qab nthab hauv tsev. Nws muab txoj kev du, txawm tias kom tiav rau kev pleev xim lossis dai kom zoo. Cellulose yog cov tsis muaj tshuaj lom, ib puag ncig phooj ywg thiab tsis muaj kev pab cuam yam ntxiv los ua gypsum.
Cellulose yog siv hauv kev tsim cov gypsum los txhim kho cov khoom ntawm gypsum. Nws ua raws li cov nplaum, tuav cov plaster ua ke thiab tiv thaiv nws los ntawm kev tawg lossis ntuag thaum nws dries. Los ntawm kev siv cellulose hauv cov sib tov stucco sib tov, koj tuaj yeem nce lub zog thiab lub zog ntawm stucco, ua rau nws nyob ntev dua.
HPMC yog lub ntuj polymer muab tau los ntawm cellulose, muaj cov saw ntev ntawm cov glucose, hloov kho los ntawm cov tshuaj tiv thaiv nrog cov tshuaj pleev thiab methylene oxide thiab methyl chloride. Cov khoom siv yog biodegradable thiab tsis muaj tshuaj lom, ib puag ncig cov khoom siv nyob ib puag ncig. Dhau li ntawd, HPMC yog dej soluble, uas txhais tau tias nws tuaj yeem sib xyaw tau yooj yim rau hauv gypsum sib tov thaum npaj nws.
Ntxiv cellulose rau stucco sib xyaw kuj tseem pab txhim kho cov khoom siv khi ntawm cov stucco. Cellulose molecules yog lub luag haujlwm rau kev sib sau cov nyiaj sib txuas ntawm stucco thiab pib hauv qab. Qhov no tso cai rau cov plaster los ua kom zoo dua rau saum npoo thiab tiv thaiv nws los ntawm kev sib cais lossis tawg.
Lwm qhov txiaj ntsig ntawm kev ntxiv cellulose rau gypsum sib tov yog tias nws pab txhim kho kev ua haujlwm ntawm Gypsum. Lub cellulose molecules ua raws li cov roj nplua nyeem, ua rau nws yooj yim dua rau cov plaster mus sib kis. Qhov no ua rau nws yooj yim rau cov plaster rau phab ntsa lossis qab nthab, muab cov chaw smoother.
Cellulose tseem tuaj yeem txhim kho qhov tsos ntawm plaster tag nrho. Los ntawm kev nce lub zog thiab kev ua haujlwm ntawm cov stucco, nws pab ua kom muaj kev du, txawm tias ua tiav dawb ntawm cov kab nrib pleb thiab kev tawg ntho. Qhov no ua rau plaster plaster kom pom kev pom zoo thiab yooj yim pleev xim lossis dai kom zoo.
Ntxiv rau cov txiaj ntsig teev saum toj no, cellulose tseem ua rau muaj hluav taws kub tiv thaiv stucco. Thaum nws tau ntxiv rau Gypsum sib tov, nws tuaj yeem pab qeeb kis tus kab hluav taws los ntawm kev tsim cov thaiv ntawm hluav taws thiab phab ntsa lossis qab nthab saum npoo.
Siv cellulose hauv Gypsum chaw tsim khoom kuj muaj ntau cov nyiaj pab ib puag ncig. Cov khoom siv yog biodegradable thiab tsis muaj tshuaj lom, tsis muaj mob rau ib puag ncig thiab tib neeg kev noj qab haus huv. Ib qho ntxiv, txij li cellulose nce lub zog thiab cov kav ntev ntawm plaster, nws pab txo tus nqi ntawm lub sijhawm. Qhov no txo cov khib nyiab tsim thiab pab kom txuag tau cov cuab yeej.
Cellulose yog ib qho tseem ceeb ntawm gypsum. Ntxiv rau nws rau cov dej stucco pab txhawm rau txhim kho lub zog, durability, kev ua haujlwm thiab pom ntawm stucco. Ntxiv rau, nws muab ntau qhov kev pab ib puag ncig uas pab txo qhov xav tau ntawm kev saib xyuas lub sijhawm ntev. Siv cellulose hauv gypsum yog ib kauj ruam tseem ceeb ntawm kev tsim kom muaj kev ruaj khov thiab ib puag ncig cov ntaub ntawv hauv tsev.
