Hydroxyethylcellulose thiab nws siv

Hydroxyethylulose (HEC) yog dej-soluble polymer muab los ntawm cellulose, lub ntuj polymer pom hauv cov nroj tsuag. Nws yog tsim los ntawm kev hloov kho tshuaj lom neeg ntawm cellulose, uas hydroxyethyl pab pawg tau qhia rau lub cellulose caj qaum. HEC muaj ntau hom kev siv hla kev lag luam sib txawv vim nws cov khoom tshwj xeeb. Nov yog qee qhov kev siv ntawm hydroxyethylcellulose:

1. Cov khoom siv saib xyuas tus kheej: HEC tau dav siv hauv kev lag luam kev saib xyuas ntawm kev saib xyuas tus kheej xws li cov tshuaj ntxuav tes, thiab cov tshuaj ntxuav cev, cream, tshuaj ntsuab, thiab gels. Nws txhim kho cov viscosity thiab kev ntxhib los mos ntawm cov khoom lag luam no, txhim kho lawv cov kev ua tau zoo thiab cov cwj pwm xav tau.
2. Cov xim tsev thiab txheej: HEC tau ua haujlwm raws li cov tuab tuab thiab rheology kho hauv cov xim tha xim av, pleev xim, thiab cov nplaum. Nws pab tswj cov khoom ntws ntawm cov qauv no, txhim kho lawv cov yam ntxwv thov thiab ua kom tau txais kev pab them nqi rau lawv.
3. Kws Tshuaj Kho Mob: Hauv kev lag luam kev lag luam, hauv cov phau ntawv, zaj duab xis-yav dhau los, thiab cov kev daws teeb meem ophthalmic, thiab kev ncua ntawm ncauj. Nws pab hauv kev tsim cov ntsiav tshuaj nrog cov khoom siv tawv tawv thiab ua kom muaj kev ruaj ntseg thiab pab txhim kho kev ruaj khov thiab cov tshuaj lom neeg ntawm cov tshuaj.
4. Cov khoom siv tsim kho: HEC ntxiv rau kev tsim kho cov ntaub ntawv xws li cov centent-raws li cov cortars, thiab grouts raws li tus neeg saib xyuas cov tuab thiab dej rov qab. Nws txhim kho cov haujlwm ua haujlwm thiab cov nplaum ntawm cov ntaub ntawv no, txhim kho lawv qhov kev ua tau zoo thiab kav ntev.
5. Cov khoom noj khoom noj: Thaum tsis tshua muaj, HEC kuj tseem siv tau hauv cov khoom lag luam khoom noj ua cov neeg sawv cev tuab thiab muaj stabilizer thiab stabilizer. Nws pab txhim kho cov kev ntxhib los mos thiab qhov ncauj ntawm cov khoom lag luam xws li cov kua ntxwv, hnav khaub ncaws, thiab cov khoom qab zib.
6. Kev Siv Khoom Siv: HEC pom cov ntawv thov hauv ntau cov txheej txheem muaj, suav nrog kev tsim qauv ntawv, textile luam ntawv, thiab drilling kua. Nws pab ua cov tuab dua, raug tshem tawm tus neeg sawv cev, thiab kev tiv thaiv kev tiv thaiv hauv cov ntawv thov no, ua rau cov txheej txheem ua haujlwm thiab cov khoom lag luam zoo.

Zuag qhia tag nrho, Hydroxyethylcellulose yog ib tug ntau ntau yam polymer nrog ntau yam ntawm kev siv thoob plaws ntau yam kev lag luam. Nws cov dej-solubility, thickening muaj peev xwm, thiab compatening muaj peev xwm nrog lwm cov khoom xyaw ua rau nws muaj txiaj ntsig ntxiv hauv ntau daim ntawv thiab cov khoom lag luam.
