Lub luag haujlwm ntawm cellulose hauv plastering cug

Plastering coll yog ib cov khoom siv uas nquag siv hauv kev tsim kho vaj tse. Nws lub hom phiaj yog los npog thiab tiv thaiv phab ntsa lossis ceilings, muab ib qho chaw du rau kev pleev xim lossis wallpaper. Plastering cug feem ntau yog tsim ntawm ntau cov ntaub ntawv, suav nrog cov cement, xuab zeb, dej thiab ntau yam ntxiv. Ib qho ntawm cov tshuaj ntxiv no, cellulose, plays lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo, ruaj khov thiab sib xyaw ntawm plastering cull.

Cellulose yog dab tsi?

Cellulose yog cov carbohydrate tseem hu ua polysaccharide. Nws yog ib qho tseem ceeb ntawm cov nroj tsuag ntawm tes, muab kev txhawb nqa cov txheej txheem thiab kev tiv thaiv. Cellulose muaj nyob hauv ntau cov khoom ntoo, suav nrog cov ntoo, paj rwb, thiab xyoob. Nws muaj ntau yam khoom xav tau, suav nrog kev ruaj khov, biodegradable, thiab ib puag ncig phooj ywg.

Lub luag haujlwm ntawm cellulose hauv plastering cug

Cellulose tau ntxiv rau plastering collhiv tshuaj kom txhim kho nws cov khoom thiab kev ua tau zoo. Nov yog qee cov txiaj ntsig ntawm cellulose rau plastering cug.

Txhim Kho Kev Ua Haujlwm

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev ntxiv cellulose los plastering cull yog tias nws txhim kho nws cov haujlwm ua haujlwm. Lub cellulose fibers ua li cov phau ntawv, tuav rau lwm yam ntawm cug cug ua ke. Qhov no pab tsim kom muaj kev sib xyaw du, tau siv tau yooj yim uas tuaj yeem siv covyees rau phab ntsa lossis qab nthab. Ntxiv cellulose tseem txo cov dej uas yuav tsum tau muab kauv cug tshuaj khib, ua rau nws tsis tshua raug ntes los yog shrinkage.

Dej ceev

Lwm qhov txiaj ntsig ntawm cellulose hauv plastering mortars yog tias nws txhim kho dej khaws cia. Cellulose fibires yog mas nqus tau, uas txhais tau tias lawv tuaj yeem pab khaws cov dej noo hauv lub tshuaj khib sib xyaw. Qhov no yog qhov tseem ceeb kom ua tiav txoj kev sib khi zoo ntawm cov kab tshuaj khib thiab qhov pib hauv qab. Thaum plastering, nws yog ib qho tseem ceeb uas cov dej nyob hauv kev sib tov maj mam maj mam kom lub plaster muaj sijhawm txaus los ua raws li phab ntsa thiab ua ib qho kev sib raug zoo.

Txhim Kho Adhesion

Cellulose tseem ua lub luag haujlwm tseem ceeb hauv kev txhim kho txoj kev sib sau ua ke ntawm plastering cug. Thaum sib xyaw nrog cov cement thiab xuab zeb, cellulose cov fibers pab khi cov sib tov sib xyaw ua ke, tsim cov khoom siv muaj zog thiab ruaj khov. Tsis tas li ntawd, cov fibers pab tiv thaiv kev tawg thiab shrinkage, uas tuaj yeem ua rau stucco cais tawm ntawm phab ntsa.

Txo cov shrinkage

Los ntawm kev ntxiv cellulose rau plastering de plastering deastrars, cov neeg tsim vaj tse kuj tuaj yeem txo cov shrinkage hauv cov khoom kawg. Shrinkage tshwm sim ua cov tshuaj pleev ib ce, ua rau nws mus ntsws thiab rub tawm ntawm phab ntsa. Cellulose fiber noo noo noo thiab tom qab ntawd tso nws qeeb, pab kom txo kom qhuav thiab shrinkage. Qhov no pab kom paub tseeb tias cov plastering tshuaj yuav nyob ruaj khov thiab tsis tawg lossis rub tawm ntawm phab ntsa.

Cellulose yog qhov tseem ceeb ntxiv hauv plastering colling. Nws ntxiv kev txhim kho cov haujlwm, dej nplaum thiab shrinkage cov khoom ntawm lub tshuaj khib, tsim cov khoom siv ruaj khov thiab muaj cov khoom siv ruaj khov. Cov neeg tsim tsev thiab cov tswv tsev muaj txiaj ntsig los ntawm kev siv cellulose hauv plastering mortars, kom muaj ntsa loog thiab nthab nyob du, txawm thiab muaj zog tau ntau xyoo los.
