Cov hmoov txhuv nplej siab ether yog cov ntsiab lus dav dav rau cov chav kawm ntawm cov hmoov txhuv nplej siab hloov pauv uas muaj ether bonds hauv cov molecule, tseem hu ua etherified starch, uas yog siv dav hauv tshuaj, zaub mov, textile, papermaking, tshuaj niaj hnub, roj av thiab lwm yam lag luam.Niaj hnub no peb feem ntau piav qhia lub luag haujlwm ntawm cov hmoov txhuv nplej siab ether hauv mortar:
1) Thicken lub mortar, nce lub anti-sagging, anti-sagging thiab rheological zog ntawm lub mortar
Piv txwv li, nyob rau hauv kev tsim kho ntawm pobzeb nplaum, putty, thiab plastering mortar, tshwj xeeb tshaj yog tam sim no hais tias txhua yam tshuaj tsuag yuav tsum muaj fluidity, xws li nyob rau hauv gypsum-raws li mortar, nws yog ib qho tseem ceeb tshwj xeeb tshaj yog (tshuab-txhaj tshuaj gypsum yuav tsum tau muaj fluidity tab sis yuav ua rau loj sagging. , starch Ether tuaj yeem ua rau qhov tsis txaus).Ntawd yog, thaum siv lub zog sab nraud, qhov viscosity txo qis, txhim kho kev ua haujlwm thiab lub zog, thiab thaum lub zog sab nraud raug tshem tawm, qhov viscosity nce, txhim kho cov sagging kuj.Rau qhov tam sim no sib txawv ntawm thaj tsam ntawm cov pobzeb, ntxiv cov hmoov txhuv nplej siab ether tuaj yeem txhim kho cov nplaum tiv thaiv ntawm cov nplais nplaum.
2) Lub sijhawm qhib sijhawm txuas ntxiv
Rau cov nplais nplaum, nws tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov pobzeb tshwj xeeb nplaum (Class E, 20min txuas mus rau 30min kom ncav cuag 0.5MPa) uas txuas ntxiv lub sijhawm qhib.Cov hmoov txhuv nplej siab ether tuaj yeem ua rau saum npoo ntawm gypsum puag thiab cement mortar smooth, yooj yim rau kev thov, thiab muaj cov nyhuv zoo nkauj.Nws yog ib qho tseem ceeb heev rau plastering mortar thiab nyias txheej zoo nkauj mortar xws li putty.
1. Cov hmoov txhuv nplej siab ether tuaj yeem txhim kho cov khoom tiv thaiv sag thiab tiv thaiv plam ntawm mortar
Cellulose ether feem ntau tsuas tuaj yeem txhim kho cov viscosity thiab dej tuav ntawm lub cev tab sis tsis tuaj yeem txhim kho cov khoom tiv thaiv sagging thiab tiv thaiv plam.
2. Thickening thiab viscosity
Feem ntau, cov viscosity ntawm cellulose ether yog txog kaum tawm txhiab, thaum lub viscosity ntawm starch ether yog ob peb puas mus rau ob peb txhiab, tab sis qhov no tsis tau txhais hais tias cov khoom thickening ntawm starch ether rau mortar tsis zoo li cov cellulose ether, thiab lub thickening mechanism ntawm ob yog txawv.
3. Kev ua haujlwm tsis zoo
Piv nrog rau cellulose ethers, hmoov txhuv nplej siab ethers tuaj yeem nce qhov txiaj ntsig ntawm cov pobzeb nplaum, yog li txhim kho lawv cov khoom tiv thaiv plam.
4. Cua-entraining
Cellulose ether muaj cov cuab yeej ua kom huab cua muaj zog, thaum cov hmoov txhuv nplej siab ether tsis muaj cua nkag mus.
