Hydroxypropyl Methylcellulose khoom thiab lawv siv

Hydroxypropyl Methylcellulose (HPMC) yog ntau yam cellulose ether siv dav hauv ntau lub lag luam vim nws cov khoom tshwj xeeb. Nov yog qee yam HPMC cov khoom lag luam thiab lawv cov ntawv thov:

1. Kev tsim kho qib HPMC:
   • Daim ntawv thov: Siv los ua cov thickener, dej tuav tus neeg sawv cev, thiab khi rau hauv cov ntaub ntawv tsim kho xws li cement-based mortars, pobzeb adhesives, renders, grouts, thiab self-leveling compounds.
   • Cov txiaj ntsig: Txhim kho kev ua hauj lwm, adhesion, dej tuav, sag kuj, thiab durability ntawm cov ntaub ntawv siv. Txhim kho daim ntawv cog lus muaj zog thiab txo qhov tawg.
2. Pharmaceutical Qib HPMC:
   • Daim ntawv thov: Siv los ua ib daim ntawv khi, tus neeg ua yeeb yaj kiab, cov tshuaj tsis sib haum, thiab cov neeg tso tawm tso tawm hauv cov tshuaj xws li ntsiav tshuaj, tshuaj ntsiav, tshuaj pleev, thiab tshuaj pleev qhov muag.
   • Cov txiaj ntsig: Muab kev tswj kev tso tawm ntawm cov khoom xyaw nquag, txhim kho cov ntsiav tshuaj cohesion, ua kom yooj yim tshem tawm cov tshuaj, thiab txhim kho cov tshuaj pleev ib ce 'rheology thiab stability.
3. Khoom noj khoom haus qib HPMC:
   • Daim ntawv thov: Siv ua cov thickener, stabilizer, emulsifier, thiab zaj duab xis-yav dhau los hauv cov khoom noj xws li kua ntses, hnav khaub ncaws, khoom qab zib, khoom noj siv mis, thiab cov khoom noj nqaij.
   • Cov txiaj ntsig: Txhim khu kev ntxhib los mos, viscosity, thiab qhov ncauj qhov ncauj ntawm cov khoom noj. Muab stability, tiv thaiv syneresis, thiab txhim kho khov-thaw stability.
4. Qib Kev Kho Tus Kheej HPMC:
   • Daim ntawv thov: Siv rau hauv cov tshuaj pleev ib ce, cov khoom tu tawv nqaij, cov khoom tu plaub hau, thiab cov khoom tu qhov ncauj ua cov thickener, suspending agent, emulsifier, film-former, thiab binder.
   • Cov txiaj ntsig: Txhim kho cov khoom zoo nkauj, viscosity, stability, thiab tawv nqaij. Muab moisturizing thiab conditioning teebmeem. Txhim kho cov khoom sib kis thiab cov khoom ua yeeb yaj kiab.
5. Muaj Qib HPMC:
   • Daim ntawv thov: Siv ua cov thickener, binder, suspending agent, thiab stabilizer nyob rau hauv cov ntaub ntawv siv xws li adhesives, xim, coatings, textiles, thiab ceramics.
   • Cov txiaj ntsig: Txhim kho rheology, workability, adhesion, thiab stability ntawm industrial formulations. Txhim kho cov khoom ua tau zoo thiab ua cov yam ntxwv.
6. Hydrophobic HPMC:
   • Daim ntawv thov: Siv rau hauv cov ntawv tshwj xeeb uas yuav tsum tau muaj dej tsis kam los yog cov khoom tiv thaiv noo noo, xws li hauv cov txheej txheem dej tsis zoo, cov nplaum tiv thaiv cov nplaum, thiab cov sealants.
   • Cov txiaj ntsig: Muab cov dej ua kom zoo dua qub thiab cov khoom tiv thaiv noo noo piv rau cov qauv HPMC qib. Haum rau cov ntawv thov raug cov av noo siab lossis noo noo.
