Yuav ua li cas koj ua ethyl cellulose?

Ethyl cellulose yog ib qho hluavtaws polymer ua los ntawm cellulose, ib qho organic compound pom hauv cov nroj tsuag. Nws yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab ntsev uas yog insoluble hauv dej thiab feem ntau cov kuab tshuaj organic. Ethyl cellulose EC yog siv rau ntau yam kev siv, nrog rau cov txheej txheem, cov nplaum, thiab cov tshuaj.

Cov txheej txheem ntawm kev ua ethyl cellulose muaj ob peb kauj ruam. Thawj kauj ruam yog kom tau txais cellulose, uas tuaj yeem tau txais los ntawm cov nroj tsuag xws li paj rwb, ntoo, lossis xyoob. Cov cellulose yog tom qab ntawd kho nrog cov kua qaub uas muaj zog, xws li sulfuric acid, txhawm rau rhuav tshem cov cellulose rau hauv nws cov khoom qab zib molecules. Cov piam thaj molecules yog tom qab ntawd ua rau muaj ethyl cawv los ua ethyl cellulose.

Cov ethyl cellulose ces purified los ntawm tus txheej txheem hu ua fractional nag lossis daus. Qhov no suav nrog ntxiv cov kuab tshuaj rau cov tshuaj ethyl cellulose, uas ua rau cov ethyl cellulose precipitate tawm ntawm cov tshuaj. Lub precipitated ethyl cellulose yog ces sau thiab qhuav.

Cov kauj ruam kawg hauv cov txheej txheem yog hloov cov qhuav ethyl cellulose rau hauv cov hmoov. Qhov no yog ua los ntawm kev sib tsoo cov ethyl cellulose rau hauv cov hmoov zoo. Tom qab ntawd cov hmoov yog npaj siv rau ntau yam kev siv.

Ethyl cellulose yog cov khoom siv ntau yam uas tuaj yeem siv rau ntau yam kev siv. Nws yog siv rau hauv coatings, adhesives, thiab pharmaceuticals, thiab tuaj yeem siv los tsim cov yeeb yaj kiab, fibers, thiab gels. Nws kuj tseem siv rau hauv kev tsim cov xim, inks, thiab lwm yam khoom. Ethyl cellulose kuj tseem siv los ua cov thickening tus neeg sawv cev hauv cov khoom noj khoom haus, thiab ua kom stabilizer hauv tshuaj pleev ib ce.
