   • Mortars thiab Renders: Nws txhim khu kev ua haujlwm, tuav dej, thiab adhesion hauv cement-based mortars thiab renders.
   • Self-leveling Compounds: HPMC pab kom ua tiav cov dej ntws zoo, theem, thiab qhov chaw tiav hauv qhov sib txuas ntawm tus kheej.
   • Sab nrauv Rwb thaiv tsev thiab Finish Systems (EIFS): Nws txhim khu kev tiv thaiv tawg, adhesion, thiab kav ntev hauv EIFS formulations.
2. Pharmaceuticals:
   • Daim Ntawv Siv Hauv Qhov Ncauj: HPMC yog siv los ua tus neeg sawv cev thickening, binder, thiab sustained-tso matrix hauv cov ntsiav tshuaj, tshuaj ntsiav, thiab kev ncua.
   • Ophthalmic Solutions: Nws txhim kho viscosity, lubrication, thiab tuav lub sij hawm nyob rau hauv ophthalmic daws thiab qhov muag tee.
3. Kev lag luam zaub mov:
   • Thickening Agent: HPMC yog siv los ua cov thickener, stabilizer, thiab emulsifier hauv cov khoom noj xws li kua ntses, kua zaub, thiab khoom qab zib.
   • Glazing Agent: Nws muab glossy tiav thiab txhim kho kev ntxhib los mos hauv cov khoom qab zib thiab cov khoom ci.
4. Cov Khoom Siv Kho Tus Kheej:
   • Tshuaj pleev ib ce: HPMC ua ib zaj duab xis yav dhau los, thickener, thiab stabilizer nyob rau hauv cov tshuaj pleev ib ce xws li cream, tshuaj pleev ib ce, thiab cov khoom tu plaub hau.
   • Cov tshuaj pleev ib ce: Nws txhim kho viscosity, kis tau, thiab khaws cia noo noo hauv cov tshuaj pleev ib ce xws li cream thiab gels.
5. Kev Siv Hluav Taws Xob:
   • Xim thiab Txheej: HPMC txhim kho rheological zog, tuav dej, thiab tsim zaj duab xis hauv cov xim, txheej, thiab cov nplaum.
   • Detergents: Nws ua hauj lwm raws li ib tug thickening neeg sawv cev, stabilizer, thiab binder nyob rau hauv detergent formulations.

Cov txiaj ntsig:

1. Kev tuav dej: HPMC muaj cov khoom tuav dej zoo, uas txhim kho kev ua haujlwm thiab qhib lub sijhawm ntawm cov khoom siv xws li mortars, adhesives, thiab renders.
2. Txhim Kho Kev Ua Haujlwm Zoo: Nws txhim kho kev ua haujlwm thiab kev nthuav dav ntawm cov qauv, tso cai rau kev tuav tau yooj yim dua, thov, thiab ua tiav.
3. Adhesion Enhancement: HPMC txhim kho adhesion ntawm ntau yam substrates, txhawb kev ruaj khov thiab ruaj khov rau hauv cov khoom siv thiab txheej txheej.
4. Thickening thiab Stabilizing: Nws ua raws li tus neeg sawv cev thickening thiab stabilizer nyob rau hauv cov khoom noj khoom haus, tshuaj, thiab kev tsim formulations, muab qhov xav tau kev ntxhib los mos thiab sib xws.
5. Kev Tsim Zaj Duab Xis: HPMC tsim cov yeeb yaj kiab hloov tau yooj yim thiab zoo ib yam thaum ziab, pab txhawb kev txhim kho cov khoom thaiv, khaws noo noo, thiab ci ntsa iab hauv cov coatings thiab cov khoom tu tus kheej.
6. Biodegradability: HPMC yog biodegradable thiab ib puag ncig tus phooj ywg, ua rau nws yog ib qho kev xaiv rau ntsuab thiab ruaj khov formulations.
7. Tsis muaj tshuaj lom thiab nyab xeeb: Nws feem ntau lees paub tias muaj kev nyab xeeb (GRAS) los ntawm cov tswj hwm kev tswj hwm thiab tsis ua rau muaj kev phom sij rau kev noj qab haus huv thaum siv raws li qhia hauv cov qauv.
8. Versatility: HPMC tuaj yeem tsim kho kom tau raws li cov kev thov tshwj xeeb los ntawm kev kho qhov tsis xws li qhov hnyav molecular, qib kev hloov pauv, thiab qhov loj me, ua rau nws haum rau ntau yam kev lag luam thiab kev siv.

Hydroxypropyl Methylcellulose hmoov muaj ntau cov txiaj ntsig thoob plaws ntau yam kev lag luam, pab txhawb kev txhim kho kev ua haujlwm, kev ua haujlwm, thiab kev ruaj khov hauv ntau yam kev tsim thiab cov khoom.
