Cellulose ethers yog ib pawg ntawm ntau yam additives lug siv nyob rau hauv kev tsim kho cov ntaub ntawv vim lawv muaj peev xwm los hloov ntau yam khoom xws li viscosity, dej tuav, thiab adhesion. Txawm hais tias lawv muaj ntau qhov zoo, cellulose ethers kuj tuaj nrog qee qhov tsis zoo hauv kev tsim kho.
Txwv Kub Ua Haujlwm: Ib qho ntawm qhov tsis zoo ntawm cellulose ethers hauv kev tsim kho yog lawv qhov ntsuas kub tsis kam. Thaum kub siab, cellulose ethers tuaj yeem degrade, ua rau poob ntawm lawv cov txiaj ntsig zoo. Qhov kev txwv no txwv tsis pub lawv siv rau hauv cov ntawv thov uas cov ntaub ntawv raug kub siab, xws li hauv cov huab cua kub lossis ze qhov chaw kub xws li qhov cub lossis qhov cub.
Biodegradability: Thaum lub biodegradability ntawm cellulose ethers tuaj yeem ua tau zoo nyob rau hauv qee cov ntsiab lus, xws li ib puag ncig tus phooj ywg thiab yooj yim ntawm kev pov tseg, nws kuj tuaj yeem ua qhov tsis zoo hauv kev tsim kho. Hauv kev siv sab nraum zoov lossis thaj chaw uas muaj dej noo, cellulose ethers tuaj yeem degrade lub sijhawm, txo qhov ua haujlwm ntev thiab ntev ntawm cov khoom siv. Qhov no tuaj yeem ua rau tsis ua haujlwm ntxov ntxov lossis kev puas tsuaj ntawm cov qauv, yuav tsum tau saib xyuas ntau zaus lossis hloov pauv.
Dej rhiab heev: Cellulose ethers yog cov dej-soluble heev, uas tuaj yeem ua tau zoo thiab qhov tsis zoo hauv kev tsim kho. Thaum cov dej solubility tso cai rau yooj yim koom ua ke rau hauv aqueous systems thiab txhim khu kev tuav dej, nws kuj ua rau cellulose ethers raug dej puas. Nyob rau hauv ib puag ncig ntub dej los yog thaum lub sij hawm ntev raug dej, cov ntaub ntawv tsim kho uas muaj cellulose ethers tuaj yeem ua rau o, leaching, los yog poob ntawm cov qauv kev ncaj ncees, cuam tshuam qhov kev ua tau zoo thiab ruaj khov ntawm cov qauv.
Cov teeb meem kev sib raug zoo: Lwm qhov teeb meem ntawm cellulose ethers hauv kev tsim kho yog lawv cov teeb meem sib raug zoo nrog lwm cov tshuaj ntxiv lossis cov khoom xyaw uas feem ntau siv hauv cov khoom siv hauv tsev. Cellulose ethers tuaj yeem cuam tshuam nrog qee yam tshuaj lossis cov khoom sib xyaw uas muaj nyob rau hauv cov qauv, ua rau muaj kev cuam tshuam tsis zoo xws li kev txo qis, theem kev sib cais, lossis kev hloov pauv hauv rheological zog. Kev ua kom pom kev sib raug zoo feem ntau yuav tsum muaj kev hloov kho ntau yam thiab kev sim, nce qhov nyuaj thiab tus nqi.
Tus nqi siab: Muab piv rau lwm cov khoom siv ntxiv, cellulose ethers tuaj yeem kim heev, uas tuaj yeem ua rau muaj kev sib tw hauv cov nqi tsim kho. Tus nqi ntawm cellulose ethers yuav txawv nyob ntawm seb yam xws li purity, qib, thiab qhov chaw. Tsis tas li ntawd, qhov kev xav tau ntau dua kom ua tiav cov qib kev ua tau zoo tuaj yeem ua rau cov nqi nce ntxiv, tshwj xeeb tshaj yog hauv cov ntawv thov kev tsim kho loj.
Lub Sij Hawm Slow: Qee qhov xwm txheej, cellulose ethers tuaj yeem ua rau lub sijhawm txuas ntxiv lossis kho lub sijhawm hauv cov khoom siv xws li mortars, grouts, lossis coatings. Thaum qhov no tuaj yeem ua tau zoo rau qee cov ntawv thov uas xav tau kev ua haujlwm ntev lossis sijhawm qhib, nws tuaj yeem ua qhov tsis zoo thaum xav tau ceev ceev lossis kev tsim kho sai. Kev ncua sijhawm lossis kev kho tuaj yeem cuam tshuam kev tsim kho, nce nqi zog, thiab muaj feem cuam tshuam rau lub sijhawm ua haujlwm.
Muaj Peev Xwm Kev Noj Qab Haus Huv: Txawm hais tias cellulose ethers feem ntau suav hais tias muaj kev nyab xeeb rau kev siv hauv cov khoom siv, qee cov ntaub ntawv lossis cov qauv yuav ua rau muaj kev phom sij rau kev noj qab haus huv yog tias tsis muaj kev ceev faj kom raug. Kev nqus cov cellulose ether hmoov av los yog cov khoom hauv huab cua thaum tuav los yog daim ntawv thov tuaj yeem ua rau lub ntsws ua pa lossis ua rau muaj kev tsis haum rau cov tib neeg rhiab heev. Cov neeg ua haujlwm raug mob cellulose ethers yuav tsum siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab ua raws li cov lus qhia kev nyab xeeb kom txo qis kev pheej hmoo ntawm kev noj qab haus huv.
Kev cuam tshuam ib puag ncig: Txawm hais tias cellulose ethers tau muab los ntawm cov khoom siv txuas ntxiv dua tshiab xws li ntoo pulp lossis paj rwb, lawv cov txheej txheem tsim khoom thiab pov tseg tseem tuaj yeem cuam tshuam ib puag ncig. Kev kho tshuaj thiab kev ua cov txheej txheem koom nrog hauv cellulose ether ntau lawm yuav tsim cov khoom pov tseg lossis emissions uas ua rau muaj kuab paug ib puag ncig. Tsis tas li ntawd, pov tseg cov ntaub ntawv tsim kho uas muaj cov cellulose ethers thaum kawg ntawm lawv lub neej kev pab cuam yuav ua rau muaj teeb meem ntawm kev rov ua dua tshiab lossis cov txheej txheem pov tseg ib puag ncig.
thaum cellulose ethers muaj ntau yam txiaj ntsig raws li cov khoom siv ntxiv hauv kev tsim kho, suav nrog kev txhim kho kev ua haujlwm thiab kev ua haujlwm, lawv kuj tuaj nrog ntau qhov tsis zoo uas yuav tsum tau ua tib zoo xav thiab hais. Kev nkag siab txog cov kev txwv no yog qhov tseem ceeb rau kev xaiv cov khoom ntxiv uas tsim nyog thiab txhim kho cov txheej txheem tsim kho kom ntseeg tau tias muaj kev nyab xeeb, kev nyab xeeb, thiab kev ruaj khov ntawm cov qauv tsim.
