Txhim khu kev qha hydroxypropyl methylulose tus neeg muab khoom

Ntxub siab rau cellulose co. Peb muab HydroxyPropyyl methylcellulose (HPMC) nyob rau hauv lawv lub npe hu ua "ntxhov siab."

HydroxyPropyyl methylcellulose (HPMC) yog cov polymer ntau yam los ntawm cellulose, ib qho tshwm sim polymer pom hauv cov nroj tsuag. HPMC yog synthesized los ntawm kev kho cellulose los ntawm kev qhia txog ntawm hydroxyprropyl thiab methyl pawg. Qhov kev hloov pauv no txhim kho cov dej solubility, thermal gelation profess, thiab zaj duab xis-tsim muaj peev xwm ntawm cellulose, ua HPMC haum rau ntau cov ntawv thov kev lag luam.

Nov yog qee qhov khoom tseem ceeb thiab kev siv ntawm HPMC:

1. Thickening thiab khi tus neeg saib xyuas: HPMC feem ntau siv los ua tus neeg sawv cev tuab hauv ntau yam kev lag luam xws li cov tshuaj, khoom noj, thiab cov khoom noj tu mob, thiab cov khoom lag luam tu cov tshuaj. Nws txhim kho cov viscosity thiab cov qauv ntawm cov kua ua kua thiab muab cov khoom ruaj khov rau kev ncua thiab emulsions. Hauv cov chaw kuaj tshuaj, HPMC yog siv los tsim kev tso tawm-tso tawm thiab khi cov ntsiav tshuaj.
2. Zaj duab xis txheej thiab tshuaj ntsuam tawm: HPMC tau siv dav hauv cov tshuaj rau kev ua yeeb yaj kiab ntawm cov ntsiav tshuaj thiab pellets. Nws ua cov khaub ncaws hnav zoo nkauj thiab hloov tau yooj yim uas tiv thaiv cov tshuaj los ntawm noo noo, lub teeb, thiab tshuab puas. HPMC kuj tseem siv hauv kev tswj hwm cov yeeb yaj kiab los tswj hwm cov kev tso tawm ntawm cov khoom xyaw nquag.
3. Kev tsim kho thiab lub tsev ntaub ntawv: HPMC ntxiv rau cov cement-raws li cov cement-raws li cov plas-plastives los txhim kho kev ua haujlwm, khaws dej, thiab cov tshuaj nplaum. Nws txhim kho cov cohesion thiab sib xws ntawm cov khoom tsim kho, pub rau kev thov kom yooj yim dua thiab ua tau zoo dua.
4. Cov xim tsev thiab cov xim txheej txheem: HPMC tau sib xyaw ua cov xim tsev dej thiab txheej txheej ua cov tuab yaj ntaub, thiab rheology kho tshuab. Nws txhim kho cov viscosity thiab sag tiv thaiv cov xim tha xim, tiv thaiv sedimentation ntawm cov pigments, thiab txhim kho cov khoom ntawm kev sib tw thiab nce qib ntawm cov tsho tiv no.
5. Cov khoom siv saib xyuas tus kheej: HPMC yog siv hauv cov tshuaj pleev ib ce, cov tshuaj lom neeg tawv nqaij, thiab kev saib xyuas plaub hau zoo li cov binder, zaj duab xis yav tas los, thiab viscosity concififier. Nws imparts sminness thiab lotions rau cream thiab potions, muab kev ntev ntev tuav hauv cov duab plaub hau, thiab txhim kho cov qauv thiab muaj kev ruaj khov ntawm emulsions.
6. Khoom noj khoom haus thiab dej haus: hauv kev lag luam khoom noj, HPMC tau ua haujlwm ua haujlwm, thiab emulsifier hauv ntau cov kua qaub, cov khoom siv tawv, cov khoom ci. Nws txhim kho lub qhov ncauj, kev ntxhib los mos, thiab txee txee kev ruaj ntseg ntawm cov khoom noj uas tsis cuam tshuam cov tsw lossis xim.

Zuag qhia tag nrho, HPMC muaj ntau cov txiaj ntsig zoo thoob plaws kev lag luam sib txawv, ua rau nws muaj txiaj ntsig ntxiv hauv ntau cov khoom lag luam thiab cov qauv.
