Hydroxyethyl cellulose (HEC) yog cov tsis-ionic cellulose ither ua los ntawm cov ntaub ntawv polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm polymer los ntawm kev ua haujlwm ntawm lub ntsej muag. Nws yog qhov tsis muaj ntxhiab, cov tsis tau muaj hmoov lossis cov xim av dawb los tsim cov dej khov, thiab cov kev sib cais tsis muaj cuam tshuam los ntawm tus nqi PH. Nws muaj thickening, khi, dispersing, ua yeeb yaj kiab, zaj duab xis, kev ua yeeb yam, noo noo-khaws thiab ntsev-resistant cov khoom. Dav siv nyob rau hauv cov xim pleev xim, kev tsim kho, textile, tshuaj txhua hnub, ntawv, roj drilling thiab lwm yam lag luam.
Daim ntawv thov tseem ceeb:
1.Paint: Xim raws li cov dej yog hom tshuaj pleev xim rau cov organic lossis dej ua raws li cov khoom siv los yog roj av, lossis roj, nrog rau kev sib ntxiv. Cov dej pleev dej ua ke nrog kev ua tau zoo heev yuav tsum muaj kev ua haujlwm zoo heev, kev ua haujlwm zoo nkauj, thiab dej zoo khaws cia; Cellulose ether yog cov khoom lag luam uas haum tshaj plaws los muab cov khoom no.
2. Cov khoom siv ntawm kev tsim kho kev lag luam, HEC yog siv los ua cov khoom ntxiv rau cov khoom siv viscosity, ua kom zoo nkauj, suav nrog cov khoom siv asphalt), txhim kho cov khoom siv asphalt), ua kom zoo dua li asphalt), txhim kho cov khoom siv asphalt), txhim kho cov ntaub ntawv asphalt), ua kom zoo nkauj, nrog rau ashesion, ua kom zoo nkauj, thiab cov dej khov. Txhim kho lub zog ntawm cov khoom lossis cov khoom sib xyaw, txhim kho shrinkage, thiab tsis txhob ntug tawg.
3.Qhov khoom siv: HEC-kho cov paj rwb, hluavtaws muaj txiaj ntsig zoo ntxiv, ua kom hluav taws xob tsis kam, uas ua rau cov hluavtaws hluavtaws, uas ua rau lawv muaj hluav taws xob.
4.Daily Tshuaj: Cellulose ether yog qhov tseem ceeb ntxiv hauv cov khoom lag luam txhua hnub. Nws tsis tuaj yeem txhim kho cov viscosity los yog cov tshuaj pleev ib ce emulsion, tab sis kuj tseem txhim kho cov kev tawg thiab ua npuas ncauj.
5. Coverpaper: hauv kev ua teb ntawm daim ntawv ua, HEC tuaj yeem siv ua tus sawv cev txiv plig, ntxiv dag zog rau tus neeg saib xyuas thiab cov ntawv hloov kho.
6.Qhov chaw taws: HEC feem ntau yog siv los ua cov thickening thiab ruaj khov nyob rau hauv cov txheej txheem Oilfield kev kho mob. Nws yog ib qho khoom siv roj zoo. Nws tau siv dav hauv Drilling, ua tiav ua tiav, cementing thiab lwm yam kev ua haujlwm roj av hauv cov teb chaws txawv teb chaws nyob rau hauv 1960.
Lwm cov teb ntawm daim ntawv thov:
HEC tuaj yeem ua lub luag haujlwm ntawm kev lom zem adhing adhering rau cov nplooj hauv txau ua haujlwm; HEC tuaj yeem siv los ua cov tuab rau cov tshuaj tua pov tseg kom txo qis cov tshuaj drift, yog li nce cov kev siv cov txiaj ntsig ntawm kev txau cov tshuaj tsuag. HEC tuaj yeem siv ua zaj duab xis-ua tus neeg sawv cev hauv cov neeg ua kom cov neeg sawv cev noob; raws li ib tug binder nyob rau hauv kev rov ua dua tshiab ntawm cov nplooj luam yeeb. Hydroxyethyl cellulose tuaj yeem siv los ua ntxiv rau kev nce ntxiv ntawm cov ntaub ntawv fireproof, thiab tau siv dav hauv kev npaj cov hluav taws kub "thickeners". Hydroxyethyl cellulose tuaj yeem txhim kho lub zog ntub thiab shrinkability ntawm cov xis mas xuab zeb thiab sodium silicate xuab zeb tshuab.Hydroxyethyl celluloseYuav siv tau rau cov yeeb yaj kiab ntau lawm thiab ua ib qho tsis txaus siab nyob rau hauv kev tsim cov ntawv me me. Thickener nyob rau hauv cov kua nrog cov ntsev ntau ntau siv hauv kev ua yeeb yam. Siv los ua phau ntawv thiab ruaj khov rau cov tshuaj tiv thaiv fluorescent hauv fluorescent raj txheej hlau. Nws tuaj yeem tiv thaiv kev sib xyaw los ntawm cov cawv ntawm electrolyte kev siab; Hydroxyethyl cellulose tuaj yeem txhawb kev tso nyiaj tso tseg hauv Cadmium plating daws teeb meem. Tuaj yeem siv los tsim cov siab loj-zog rau Ceramics. Cov tshuaj tua dej kom tiv thaiv kom noo los ntawm nkag mus rau cab.
