Mortar yog ib qho khoom siv tseem ceeb hauv tsev uas tau siv ntau pua xyoo hauv ntau qhov chaw hauv ntiaj teb. Nws yog kev sib xyaw ntawm cov cement, xuab zeb thiab dej siv los khi lub tsev thaiv xws li cib, pob zeb lossis pob zeb ua vaj tse. Lub zog sib txuas ntawm lub mortar yog qhov tseem ceeb rau tag nrho kev ruaj ntseg thiab lub zog ntawm cov qauv. Yog li ntawd, ntau yam additives yog siv nyob rau hauv mortar mixs los txhim kho lawv cov khoom, thiab cellulose ether yog ib yam khoom zoo li no. Cellulose ethers yog cov organic tebchaw muab tau los ntawm cellulose, ib tug natural polymer pom nyob rau hauv cov nroj tsuag. Nyob rau hauv tsab xov xwm no peb yuav tham txog cov teebmeem ntawm cellulose ethers ntawm mortar bonding thiab lawv cov txiaj ntsig.
Cov nyhuv ntawm cellulose ethers ntawm cov nplaum nplaum
Cellulose ethers tau ntxiv rau hauv cov tshuaj khib nyiab los txhim kho nws txoj kev sib raug zoo. Nws ua raws li cov dej tuav cov neeg sawv cev, txhim kho kev ua haujlwm ntawm cov mortar thiab muab cov khoom sib txuas zoo dua. Nws kuj ua rau kom qhov sib xws ntawm cov mortar, ua kom yooj yim rau kev thov thiab sib kis sib npaug. Cellulose ethers ua raws li cov kua nplaum uas tuav cov cement hais ua ke, ua kom lub zog tag nrho ntawm cov mortar.
Cellulose ethers kuj muaj cov khoom tuab uas pab tiv thaiv kev sib cais ntawm cov tshuaj sib tov. Kev sib cais tshwm sim thaum cov khoom hnyav dua nkag mus rau hauv qab thiab cov khoom sib zog sib zog ntab mus rau sab saum toj, ua rau muaj kev sib xyaw tsis sib xws. Qhov no txo qis tag nrho daim ntawv cog lus lub zog ntawm lub mortar thiab cuam tshuam qhov ruaj khov ntawm cov qauv. Qhov sib ntxiv ntawm cellulose ethers tiv thaiv kev sib cais los ntawm thickening qhov sib tov, kom ntseeg tau tias cov khoom hnyav tseem raug tshem tawm hauv cov tshuaj khib nyiab.
Cov txiaj ntsig ntawm kev siv cellulose ethers hauv mortar
Txhim kho kev ua haujlwm: Ntxiv cov cellulose ethers rau hauv cov tshuaj khib sib xyaw ua kom nws ua haujlwm tau zoo. Nws ua rau nws yooj yim dua los faib cov mortar sib npaug thiab txo qhov tsim ntawm cov hnab ntim cua. Qhov no ua kom muaj kev siv tshuaj khib nyiab, muab kev sib raug zoo ntawm lub tsev thaiv.
Txhim kho daim ntawv cog lus muaj zog: Cellulose ethers txhim khu lub zog ntawm cov tshuaj khib nyiab los ntawm kev ua cov kua nplaum uas tuav cov cement hais ua ke. Qhov no ua rau muaj zog, ruaj khov dua. Kev txhim kho nyob rau hauv mortar sib xws thiab kev ua haujlwm kuj tseem pab txhim kho nws txoj kev sib raug zoo.
Txo shrinkage: mortar shrinks raws li nws dries, ua rau tawg thiab txo lub zog ntawm daim ntawv cog lus. Cellulose ethers txo qhov shrinkage ntawm mortar los ntawm kev ua kom nws workability thiab sib xws. Qhov no pab tiv thaiv cov kab nrib pleb los ntawm kev tsim, ua rau muaj kev ruaj khov dua, muaj zog dua.
Txhim kho cov dej tuav: Cellulose ether yog cov dej tuav cov dej uas pab ua kom cov mortar moist. Qhov no tiv thaiv nws los ntawm ziab tawm sai heev, uas tuaj yeem txo nws txoj kev ruaj khov thiab ua rau tawg. Kev tuav dej ntau ntxiv ntawm cov tshuaj khib kuj tseem ua rau nws qhov kev ua tau zoo tag nrho, xws li nws muaj peev xwm tiv taus huab cua thiab lwm yam ib puag ncig.
Cellulose ether yog ib qho tseem ceeb heev additive uas pab txoj kev sib raug zoo ntawm mortars. Nws ua raws li cov dej tuav cov neeg sawv cev, txhim kho kev ua haujlwm thiab sib xws, thiab tiv thaiv kev sib cais thiab shrinkage. Kev siv cov cellulose ethers nyob rau hauv mortar sib tov ua kom ruaj khov, muaj zog cov qauv uas muaj peev xwm tiv taus ib puag ncig yam tseem ceeb thiab muab lub sij hawm ntev. Yog li ntawd, nws yog ib qho tseem ceeb ntawm cov niaj hnub mortar mix.
