Cellulose ethers yog ntau yam khoom xyaw siv nyob rau hauv ntau yam kev lag luam nrog rau cov khoom noj, tshuaj thiab kev tsim kho.Hauv kev tsim kho kev lag luam, cellulose ethers yog cov khoom xyaw tseem ceeb hauv ntau cov khoom siv hauv tsev thiab cov khoom lag luam, suav nrog gypsum sprays plasters.Gypsum spray stucco yog ib qho kev xaiv nrov rau sab hauv phab ntsa thiab qab nthab tiav vim nws cov hluav taws kub zoo heev, acoustic zog thiab yooj yim ntawm daim ntawv thov.Txawm li cas los xij, qhov zoo thiab kev ua tau zoo ntawm gypsum spray plaster yog nyob ntawm ntau hom thiab tus nqi ntawm cellulose ether siv hauv kev tsim.Hauv tsab xov xwm no, peb yuav tham txog lub luag haujlwm tseem ceeb ntawm cellulose ethers hauv gypsum spray stucco.
Ua ntej delving rau hauv lub luag hauj lwm ntawm cellulose ether nyob rau hauv gypsum spray plaster, cia peb xub nkag siab tias cellulose ether yog dab tsi.Cellulose ethers yog cov tshuaj tau los ntawm cellulose, cov khoom tseem ceeb ntawm cov phab ntsa ntawm cov nroj tsuag.Nws yog cov dej-soluble polymer uas feem ntau siv los ua cov thickener, binder thiab stabilizer.Hauv kev tsim kho kev lag luam, cellulose ethers feem ntau yog siv los ua cov dej tuav dej, viscosity regulators thiab workability enhancers.
Rov qab mus rau gypsum spray stucco, cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom ntawm ntau txoj hauv kev.Ua ntej, cellulose ether ua raws li cov dej khaws cia, pab txhim kho kev ua haujlwm thiab txo qhov tawg ntawm plaster.Qhov no yog vim cellulose ether molecules yog hydrophilic, uas txhais tau hais tias lawv yooj yim nqus thiab khaws cov dej molecules, uas tiv thaiv lub plaster los ntawm ziab sai heev.Yog li ntawd, lub stucco nyob twj ywm ntub dej ntev dua, cia cov plasterer siv thiab ua kom tiav cov stucco ntau smoothly thiab tusyees.
Cellulose ethers ua raws li viscosity modifiers, pab tswj kev ntws thiab sib xws ntawm gypsum.Qhov no yog ib qho tseem ceeb tshwj xeeb nrog gypsum sprayed stucco, uas yuav tsum tau ib tug khov kho thiab txawm tsuag qauv.Qhov sib ntxiv ntawm cellulose ethers rau gypsum formulations pab kom viscosity thiab txhim kho thixotropic cwj pwm ntawm gypsum.Qhov no txhais tau hais tias lub stucco ua thicker thiab viscous ntau dua thaum tsis txau, tab sis ua kua ntau dua thiab yooj yim rau tshuaj tsuag hauv siab.Raws li qhov tshwm sim, plasterers tuaj yeem ua tiav qhov zoo ib yam thiab txawm tias cov qauv tshuaj tsuag kom zoo dua, zoo nkauj dua.
Cellulose ethers ua haujlwm ua haujlwm tau zoo, pab txhim kho kev tuav thiab ua tiav cov khoom ntawm stucco.Qhov no yog vim hais tias cov cellulose ether molecules yog ntev thiab hloov tau, cia lawv mus entangle nrog ib leeg thiab tsim ib tug peb-dimensional network nyob rau hauv lub gypsum matrix.Cov qauv network no ua rau muaj kev sib koom ua ke thiab lub zog ntawm stucco, ua rau nws tsis tshua muaj kev tawg, sag lossis ntsws.Tsis tas li ntawd, lub xub ntiag ntawm cellulose ethers nyob rau hauv stucco kuj pab txo cov cua cov ntsiab lus, yog li ua rau lub stucco lub durability thiab tsis kam mus rau dej thiab lwm yam ib puag ncig.
Cellulose ethers kuj pab txhim kho qhov hluav taws kub ntawm gypsum spray stucco.Qhov no yog vim cellulose ether yog nonflammable thiab tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj decomposing.Tsis tas li ntawd, lub xub ntiag ntawm cellulose ethers hauv gypsum pab txo cov nplaim taws thiab cov pa luam yeeb ntawm gypsum, ua rau nws muaj kev nyab xeeb thiab ntau dua cov khoom siv hluav taws xob.
Cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov zoo thiab kev ua haujlwm ntawm gypsum spray plaster.Los ntawm kev ua raws li cov dej tuav cov neeg ua hauj lwm, viscosity modifiers, workability enhancers thiab nplaim retardants, cellulose ethers pab txhim kho lub workability, sprayability, cureability, lub zog thiab durability ntawm stucco.Nyob rau hauv lem, qhov no ua rau ntau aesthetically pleasing, check thiab hluav taws-resistant upholstery ntaub ntawv.Yog li ntawd, kev siv cellulose ethers hauv gypsum sprays plasters thiab lwm yam ntaub ntawv hauv tsev yog pom zoo kom lawv cov khoom muaj txiaj ntsig tuaj yeem siv tag nrho.
