High-viscosity starch etheryog ib qho kev ua haujlwm tau txuas ntxiv siv hauv cov dej pleev dej, cov nplaum, inks, cov ntaub ntawv hauv tsev thiab lwm thaj teb. Nws tsuas yog muab sib txuas ua ke cov hmoov txhuv nplej siab nrog pawg uas muaj cov hmoov txhuv nplej siab ntau dua thiab txhim kho nws cov ntawv thov cov txiaj ntsig hauv cov chaw muaj kev lag luam sib txawv.
Lub luag haujlwm ntawm high-viscosity starch ether
Lub luag haujlwm tseem ceeb ntawm cov viscosity high-viscosity ether yog ib qho tuab. Nws tuaj yeem ua kom cov viscosity ntawm kev daws teeb meem lossis slurry thiab txhim kho lub zog rheological. Hauv cov txheej txheej hauv dej thiab cov nplaum, ntxiv rau cov txheej txheem ntawm cov khoom siv tau yooj yim los yog kev nqus dej yooj yim dhau los lossis ua kom muaj kev sib luag thiab ruaj khov ntawm txheej.
Dej retention high-viscosity hmoov txhuv nplej ether tuaj yeem txhim kho cov dej khaws cia hauv lub system. Qhov no yog qhov tseem ceeb rau kev tsim kho ntawm cov cement, gypsum thiab lwm yam ntaub ntawv hauv tsev. Los ntawm tswj tso tawm ntawm dej tso tawm, lub sijhawm tsim kho tuaj yeem txuas tau zoo heev, kev ua haujlwm tuaj yeem hloov kho tau dhau los, thiab qhov zoo ntawm cov khoom kawg tuaj yeem ua kom tiav.
Txhim kho kev kawm raug ncua nyob rau hauv cov khoom raug ncua nyob rau hauv cov khoom lag luam thiab lwm yam khoom, ntxiv rau ntawm high-viscosity hmoov ether tuaj yeem ua kom tawg thiab tsis txhob muaj nag lossis daus thiab stratification. Cov nyhuv no yog qhov tshwj xeeb yog thaum kev tsim khoom thiab cov txheej txheem cia, thiab tuaj yeem ua kom lub sijhawm ntev ruaj khov thiab muaj kev sib xws ntawm cov khoom.
Txhim kho txheej txheej viscosity siab cov hmoov txhuv nplej siab ether tuaj yeem txhim kho cov tuab, hardness thiab hnav tsis kam ntawm txheej. Hauv qee qhov tshwj xeeb txheej lossis cov qauv nplaum tshiab, ntxiv cov txiaj ntsig viscosity siab ether tuaj yeem txhim kho cov nplaum thiab huab cua tiv thaiv ntawm txheej.
Txo cov khoom siv stratification thiab kev nqus dej hauv cov khoom ua kua, tshwj xeeb tshaj yog cov txheej txheem siab thiab cov khoom lag luam muaj peev xwm ua tau zoo dua thiab tsis sib haum khoom thiab cov khoom siv kev ua haujlwm. Nws tuaj yeem pab tswj cov dej ntawm cov khoom lag luam hauv cov txheej txheem sib txawv thiab zam qhov nyuaj los ua haujlwm vim muaj kev viscosity.
Thickening thiab antifregreeze kev ua tau zoo hauv qee cov khoom lag luam uas yuav tsum tau siv rau hauv cov hmoov av tsawg ether tseem muaj cov txiaj ntsig ntawm kev txhim kho cov tshuaj antiflewaws kev ua tau zoo. Nws tuaj yeem tiv thaiv cov txheej txheej, cov nplaum, thiab lwm yam los ntawm khov lossis poob qis hauv cov khoom siv kub tsawg, thiab ua kom cov khoom siv kom paub tseeb.
Ntxiv cov nyiaj thiab cuam tshuam ntawm cov viscosity siab cov hmoov txhuv nplej siab ether
Cov nyhuv ntawm cov nyiaj sib ntxiv ntawm kev sib ntxiv ntawm cov viscosity siab starch ether ncaj qha cuam tshuam rau cov khoom rheological, kev ruaj khov thiab siv cov nyhuv kawg ntawm cov khoom. Hauv kev tsim khoom tiag tiag, kev xaiv ntawm cov nyiaj yuav tsum tau txiav txim siab raws li cov kev xav tau ntawm cov khoom lag luam tshwj xeeb.
Kev ntxiv (0.1% -1%):Hauv qee cov khoom lag luam uas muaj viscosity qis, tsis muaj viscosity siab cov hmoov txhuv nplej siab ether tuaj yeem muab cov nyhuv tuab. Nyob rau lub sijhawm no, nws tsuas yog ua lub luag haujlwm ntawm stabilizing cov kab ke raug tshem tawm thiab txhim kho cov haujlwm ua haujlwm thiab rheological cov khoom siv.
Nruab nrab (1% -3%):Hauv cov ntawv thov uas cov khoom siv rho tawm yuav tsum tau txhim kho thiab txheej txheem kev ua tau zoo dua tshiab, txuas ntxiv ntawm cov neeg viscosity siab ether yuav ua rau muaj cov nyhuv tuab dua. Cov nyiaj no feem ntau tuaj yeem ua kom muaj kev tsim kho thaum tseem ua cov txheej txheej lossis cov nplaum muaj cov xim zoo dua thiab ductility.
Ib qho ntxiv (ntau dua 3%):Thaum nws yog qhov tsim nyog kom nce viscosity los yog dej khaws cia, siab ntxiv ntawm cov viscosity siab sarge ether tuaj yeem muab cov nyhuv tuab tuab thiab muaj zog zoo dua. Txawm li cas los xij, ntau dhau yuav ua rau cov xim ntawm cov txheej lossis nplaum kom tsawg, cuam tshuam rau cov nyhuv qis, yog li nws yuav tsum tau siv nrog kev ceev faj.
Kev pheej hmoo ntawm kev siv ntau dua txawm hais tias high-viscosity harfe muaj kev hais kom zoo thiab muaj kev ruaj khov ntawm cov khoom, ntau dhau ntxiv yuavNqa cov kev cuam tshuam tsis zoo:
Txo kom tau flue:Cov tuab tuab heev yuav ua rau cov kab mob viscosity hauv viscosity ntau dhau, muaj cov nplaum thiab cuam tshuam rau cov txheej txheem ua haujlwm thiab ua tau zoo thaum kev tsim kho.
Nce nqi:Kev siv ntau dua ntawm cov viscosity high-viscosity yuav ua rau cov khoom siv raw ncaj qha, tshwj xeeb tshaj yog nyob rau hauv cov khoom lag luam loj, feem ntau ntawm tus nqi tsis tuaj yeem tsis quav ntsej.
Tsis ncaj faib:Ntau dhau-viscosity ether yuav ua rau faib cov khoom lag luam, thickenity thickening ntawm cov khoom lag luam zoo nkauj thiab cov tsos zoo ntawm cov khoom kawg.
High-viscosity Cov hmoov av muaj ib daim ntawv thov tseem ceeb hauv ntau daim ntawv thov kev lag luam, feem ntau nyob rau hauv thickening, dej rov qab, txhim kho kev kawm. Kev xaiv ntawm tus nqi ntawm kev ntxiv yuav tsum tau hloov kho raws li cov kev tseev kom muaj. Kev siv uas tsim nyog tuaj yeem ua kom zoo tshaj tawm cov khoom lag luam, thaum siv ntau dhau yuav coj cov kev mob tshwm sim. Yog li ntawd, hauv kev tsim tiag, nws yog qhov tsim nyog tswj hwm tus nqi ntawm high-viscosity ether raws li cov yam ntxwv sib txawv raws li cov khoom sib txawv kom ua tiav cov nyhuv zoo.
