Vim lawv cov tshuaj lom neeg tshwj xeeb, cellulose ethers yog cov khoom xyaw tseem ceeb hauv kev tsim cov xim latex.Lawv yog siv nyob rau hauv cov xim latex li thickeners, rheology modifiers, tiv thaiv colloids thiab dej tuav cov neeg ua haujlwm.Cellulose ethers ua lub luag haujlwm tseem ceeb hauv kev tsim thiab siv cov xim latex, thiab lawv cov kev siv tau dhau los ua ib qho chaw hauv kev lag luam coatings.
Thickeners thiab Rheology Modifiers:
Ib qho ntawm cov haujlwm tseem ceeb ntawm cellulose ethers yog cov thickeners thiab rheology modifiers.Rheology yog kev kawm txog kev deformation thiab ntws ntawm cov teeb meem, thiab nws plays lub luag haujlwm tseem ceeb hauv kev siv cov txheej txheem.Rheology modifiers yog ntxiv rau cov xim pleev xim los tswj cov yam ntxwv ntws ntawm cov xim thiab ua kom muaj kev ntxhib los mos thiab kev pab cuam zoo ib yam.Los ntawm kev ua cov thickeners thiab rheology modifiers, cellulose ethers tuaj yeem ua cov xim latex thiab ua kom yooj yim rau kev thov.
Cellulose ethers yog cov dej-soluble polymers uas muaj tshuaj zoo ib yam li cellulose, ib txwm tshwm sim polymer pom nyob rau hauv cov nroj tsuag.Cov yam ntxwv tshwj xeeb ntawm cov cellulose ethers tso cai rau lawv ua kom cov xim latex tsis muaj kev cuam tshuam rau nws cov viscosity, kom cov xim muaj tus du, txawm tias zoo nkauj.
Vim lawv cov khoom thickening, cellulose ethers kuj txhim kho cov nplaum nplaum ntawm cov txheej txheem.Los ntawm kev ua kom cov tuab ntawm cov xim pleev xim rau cov yeeb yaj kiab, nws pab txhim kho kev sib raug zoo ntawm cov xim thiab qhov chaw, ua kom cov xim zoo nkauj ntev.
Kev tiv thaiv colloid:
Cellulose ethers yog cov zoo tiv thaiv colloids uas pab stabilize colloidal hais nyob rau hauv cov xim latex.Colloids yog cov khoom me me dispersed hauv nruab nrab, qhov no, xim.Kev ruaj ntseg ntawm cov khoom no yog qhov tseem ceeb rau kev tswj xyuas tag nrho kev ncaj ncees ntawm txheej txheej txheej.
Ntxiv cellulose ethers rau txheej formulations xyuas kom meej tias cov colloidal hais nyob twj ywm tusyees dispersed nyob rau hauv lub txheej, tiv thaiv kev tsim ntawm clumps.Tsis tas li ntawd, cov khoom tiv thaiv colloid ntawm cellulose ethers tiv thaiv cov xim latex los ua tuab dhau los yog tawv dhau sijhawm.Qhov no nyob rau hauv lem kom ntseeg tau tias cov xim yog ib qho yooj yim mus thov thiab nyob ruaj khov thiab zoo ib yam thaum siv.
Kev tuav dej:
Lwm yam khoom tseem ceeb ntawm cellulose ethers yog lawv cov dej tuav.Nyob rau hauv cov xim formulations, dej yog feem ntau ntxiv raws li ib tug diluent los tsim ib tug du, txawm zoo nkauj thiab txhim kho daim ntawv thov zog ntawm cov xim.Txawm li cas los xij, dej kuj tuaj yeem ua rau cov xim kom qhuav sai heev, ua rau kev sib txuas ntawm cov xim thiab qhov chaw tsis muaj zog.
Los ntawm khaws cov dej noo, cellulose ethers xyuas kom meej tias cov txheej txheem tseem hydrated thoob plaws hauv daim ntawv thov, tiv thaiv nws los ntawm ziab sai heev.Qhov no nyob rau hauv lem tso cai rau cov xim kom qhuav tusyees thiab tsim ib tug muaj zog, ntev daim ntawv cog lus nrog nto.
nyob rau hauv xaus:
Cellulose ethers yog ib qho tseem ceeb ntawm cov xim latex vim lawv cov tshuaj lom neeg tshwj xeeb.Lawv yog siv nyob rau hauv txheej formulations li thickeners, rheology modifiers, tiv thaiv colloids thiab dej tuav cov neeg ua hauj.Los ntawm kev muab ntau txoj haujlwm no, cellulose ethers kom ntseeg tau tias cov xim latex nyob ruaj khov, zoo ib yam thiab siv tau yooj yim.Lawv siv tau hloov pauv kev lag luam coatings, thiab lawv qhov zoo tau lees paub los ntawm cov tuam ntxhab thiab cov neeg siv khoom.
