Hydroxyethyl methyl cellulose chaw tsim khoom

Ntxheej Cellulose Co., Ltd yog ib qho prenessional manufacturers tsim hydroxyethy cellulose (Hemc) kom tau raws li cov kev xav tau ntawm cov kev lag luam, hemc) thiab cov xim pleev xim, tshuaj pleev ib ce, thiab ntau dua.

Hydroxyethy cellulose (HEMC) yog lub cellulose ether uas yog rau tsev neeg ntawm cellulose derivatives. Nws yog synthesized los ntawm kev hloov kho tshuaj lom neeg ntawm ntuj cellulose, feem ntau yog muab los ntawm ntoo pulp lossis paj rwb.

Ntawm no yog cov yam ntxwv tseem ceeb thiab siv ntawm hydroxyethyl methyl cellulose:

1. Cov qauv tshuaj:

• HEMC yog tus cwj pwm los ntawm kev qhia txog ob pawg methrotyl thiab methyl pawg mus rau lub cellulose rau lub pob cellulose los ntawm cov txheej txheem tshuaj hu ua etherification.

2. Lub zog lub cev:

• Zog: Zoo, dawb rau cov hmoov dawb.
• Solubility: soluble hauv dej txias, sib sau meej thiab khov kho cov kev daws teeb meem.
• Viscosity: viscosity ntawm HEMC cov kev daws teeb meem tuaj yeem hloov kho los ntawm kev xaiv cov qib tsim nyog, kev xav tau, thiab kub.

3. Cov haujlwm tseem ceeb thiab siv:

• Tus neeg saib xyuas tuab: HEMC feem ntau siv los ua tus neeg sawv cev tuab ntawm ntau cov qauv, suav nrog cov xim av, pleev xim, cov khoom lag luam nplaum, thiab cov khoom tu tus kheej. Nws imparts viscosity thiab txhim kho cov ntawv sib xws ntawm cov ntaub ntawv no.
• Dej khaws cia: hauv kev tsim kho cov ntaub ntawv: hauv kev tsim kho cov khoom siv pob thiab groutts, hemc txhim kho cov dej ua kom qhuav, tiv thaiv kom qhuav thiab ua kom muaj zog ua haujlwm.
• Zaj duab xis: Hemp tuaj yeem pab tau rau kev tsim cov yeeb yaj kiab, ua kom haum rau kev siv hauv cov tshuaj pleev cov tshuaj pleev thiab cov khoom siv kom zoo nkauj.
• Stabilizer: hauv emulsions thiab raug tshem tawm, hemc ua raws li lub stabilizer, tiv thaiv theem sib cais.

4. Kev Lag Luam Kev Lag Luam:

• Kev lag luam tsim kev tsim kho: Siv hauv kev nplua nuj, grouts, cov nplaum sib xyaw, thiab lwm yam kev tsim kho cov khoom siv.
• Xim thiab pleev xim kev lag luam: suav nrog cov xim pleev xim rau cov dej thiab txheej ci kom hloov viscosity thiab txhim kho cov ntawv thov.
• Cov tshuaj pleev ib ce thiab kev lag luam saib xyuas tus kheej: siv hauv cream, tshuaj, tshuaj zawv plaub hau, thiab lwm yam kev ua kom zoo nkauj thiab ruaj khov.
• Kws Tshuaj Kho Mob: Ua haujlwm hauv cov kws tshuaj ua haujlwm zoo li cov binder, ua txhaum cai, lossis zaj duab xis-forming tus neeg sawv cev.

5. Qib thiab specifications:

• HEMC muaj nyob rau ntau qib nrog cov viscosities sib txawv thiab cov qib hloov kom haum rau cov kev tsim tshwj xeeb thoob plaws ntau yam kev lag luam.

HEMC, zoo li lwm yam kev ua kom muaj kev ua kom muaj kev nyab xeeb, muab ntau yam ntawm cov ntawv thov vim nws cov dej-solubility, biocompatibility, thiab rheological cov khoom. Qhov kev xaiv ntawm qib tshwj xeeb ntawm HEMC yog nyob ntawm cov ntawv thov thiab cov yam ntxwv xav tau yam ntxwv ntawm cov khoom kawg.
