Cellulose, tseem hu ua hydroxypropylmethylcellulose (HPMC), yog ib qho tseem ceeb ntawm gypsum. Gypsum yog cov khoom siv dav siv hauv phab ntsa thiab qab nthab. Nws muab ib tug du, txawm nto npaj rau painting los yog decorating. Cellulose yog non-toxic, environmentally friendly thiab harmless additive siv los ua gypsum.
Cellulose yog siv los tsim cov gypsum los txhim kho cov khoom ntawm gypsum. Nws ua raws li cov nplaum nplaum, tuav lub plaster ua ke thiab tiv thaiv nws los ntawm kev tawg lossis shrinking thaum nws qhuav. Los ntawm kev siv cellulose nyob rau hauv lub stucco sib tov, koj muaj peev xwm ua kom lub zog thiab durability ntawm lub stucco, ua rau nws kav ntev thiab yuav tsum tau tsawg dua kev txij nkawm.
HPMC yog cov khoom siv ntuj tsim los ntawm cellulose, muaj cov hlua ntev ntawm cov piam thaj, hloov kho los ntawm cov tshuaj tiv thaiv nrog propylene oxide thiab methyl chloride. Cov khoom siv yog biodegradable thiab non-toxic, ib puag ncig tus phooj ywg khoom. Tsis tas li ntawd, HPMC yog dej soluble, uas txhais tau hais tias nws tuaj yeem yooj yim tov rau hauv gypsum mix thaum npaj nws.
Ntxiv cellulose rau cov sib tov ntawm stucco kuj pab txhim kho cov khoom sib txuas ntawm stucco. Cellulose molecules yog lub luag haujlwm rau kev tsim cov ntawv cog lus ntawm stucco thiab hauv qab. Qhov no tso cai rau lub plaster kom ua raws li zoo dua rau saum npoo thiab tiv thaiv nws los ntawm kev sib cais los yog tawg.
Lwm qhov txiaj ntsig ntawm kev ntxiv cellulose rau gypsum sib tov yog tias nws pab txhim kho kev ua haujlwm ntawm gypsum. Cov cellulose molecules ua raws li cov roj nplua nyeem, ua kom yooj yim rau cov plaster kom sib kis. Qhov no ua rau nws yooj yim dua rau kev siv lub plaster rau phab ntsa lossis qab nthab, muab ib qho smoother nto.
Cellulose tuaj yeem txhim kho tag nrho cov tsos ntawm plaster tiav. Los ntawm kev ua kom lub zog thiab kev ua haujlwm ntawm stucco, nws pab ua kom du, txawm tias ua tiav tsis muaj kab nrib pleb thiab qhov tsis zoo. Qhov no ua rau lub plaster ntau visually txaus nyiam thiab yooj yim rau xim los yog decorate.
Ntxiv nrog rau cov txiaj ntsig tau teev tseg saum toj no, cellulose kuj tseem ua rau hluav taws kub nyhiab ntawm stucco. Thaum nws tau ntxiv rau cov gypsum sib tov, nws tuaj yeem pab txo qhov kev sib kis ntawm hluav taws los ntawm kev tsim qhov thaiv ntawm qhov hluav taws kub thiab phab ntsa lossis qab nthab.
Kev siv cellulose hauv gypsum tsim kuj muaj ntau yam txiaj ntsig ib puag ncig. Cov khoom siv yog biodegradable thiab non-toxic, harmless rau ib puag ncig thiab tib neeg noj qab haus huv. Tsis tas li ntawd, txij li thaum cellulose nce lub zog thiab kav ntev ntawm lub plaster, nws yuav pab txo qhov kev saib xyuas yuav tsum tau ua raws sijhawm. Qhov no txo cov khoom pov tseg thiab pab txuag cov peev txheej.
Cellulose yog ib qho tseem ceeb ntawm gypsum. Ntxiv rau qhov sib tov ntawm stucco pab txhim kho lub zog, durability, workability thiab tsos ntawm stucco. Ntxiv rau, nws muaj ntau yam txiaj ntsig ib puag ncig uas pab txo qis kev xav tau kev saib xyuas mus ntev. Kev siv cellulose hauv gypsum yog ib kauj ruam tseem ceeb ntawm kev tsim cov khoom tsim kom ruaj khov thiab zoo ib puag ncig.
