• Nws ua haujlwm ua tus hloov kho rheology thiab tus neeg saib xyuas dej, txhim kho kev ua haujlwm thiab teeb tsa cov yam ntxwv ntawm gypsum sib tov.
• HPMC txhim kho cov kab nrib pleb, nto tiav, thiab cov khoom siv ntawm cov khoom siv gypsum.

2. Paints, Coatings, thiab Adhesives:

ib. Paints thiab Coatings:

• HPMC tau ntxiv rau cov xim dej thiab cov txheej txheem ua cov thickener, stabilizer, thiab rheology modifier.
• Nws imparts viscosity tswj, sag tsis kam, thiab txhim kho ndlwg zog rau xim formulations.
• HPMC txhim kho kev tsim zaj duab xis, adhesion, thiab durability ntawm coatings ntawm ntau yam substrates.

b. Adhesives thiab Sealants:

• HPMC tau muab tso rau hauv cov nplaum nplaum thiab sealant formulations los txhim kho tack, adhesion, thiab rheological zog.
• Nws ua hauj lwm raws li ib tug thickening neeg sawv cev, binder, thiab zaj duab xis qub, muab stability thiab kev ua tau zoo nyob rau hauv daim ntawv thov nplaum.
• HPMC txhim khu kev sib txuas lub zog, yooj, thiab noo noo tsis kam ntawm cov khoom nplaum thiab sealant.

3. Cov Khoom Siv Tshuaj thiab Kev Kho Tus Kheej:

ib. Pharmaceutical Formulations:

• HPMC yog siv nyob rau hauv cov tshuaj formulations raws li ib tug binder, disintegrant, thiab tswj-tso tus neeg sawv cev nyob rau hauv cov ntsiav tshuaj thiab tshuaj ntsiav formulations.
• Nws txhim kho cov ntsiav tshuaj hardness, dissolution tus nqi, thiab cov tshuaj tso tawm profile, txhim khu kev xa tshuaj thiab bioavailability.
• HPMC tseem ua hauj lwm hauv cov tshuaj kho qhov muag, tshem tawm, thiab cov tshuaj pleev ib ce rau nws cov khoom mucoadhesive thiab viscoelastic.

b. Cov Khoom Siv Kho Tus Kheej:

• HPMC muaj nyob rau hauv ntau yam kev saib xyuas tus kheej thiab cov khoom kom zoo nkauj xws li cream, tshuaj pleev, tshuaj zawv plaub hau, thiab gels.
• Nws ua hauj lwm raws li ib tug thickener, emulsifier, thiab stabilizer, muab kev ntxhib los mos, zoo ib yam, thiab sensory cwj pwm rau formulations.
• HPMC txhim kho cov khoom sib kis, tsim cov yeeb yaj kiab, thiab khaws cov dej noo ntawm daim tawv nqaij thiab plaub hau.

4. Kev lag luam zaub mov thiab dej haus:

ib. Khoom noj khoom haus Additives:

• HPMC tau pom zoo siv los ua cov khoom noj khoom haus ntxiv thiab cov khoom ua kom tuab hauv ntau yam khoom noj.
• Nws yog siv rau hauv cov kua ntses, kua zaub, hnav khaub ncaws, thiab cov khoom noj khoom haus los txhim kho kev ntxhib los mos, viscosity, thiab qhov ncauj.
• HPMC kuj tseem ua haujlwm ruaj khov thiab emulsifier hauv cov khoom noj thiab dej haus ua tiav.

5. Lwm yam kev siv hauv kev lag luam:

ib. Textile thiab Ntawv Industries:

• HPMC yog ua hauj lwm hauv textile sizing, xov, thiab luam ntawv daim ntawv thov los txhim kho cov xov paj zog, ntaub kov, thiab luam ntawv zoo.
• Hauv kev lag luam ntawv, HPMC yog siv los ua tus neeg sawv cev txheej, khi, thiab tus neeg saib xyuas qhov loj me los txhim kho cov khoom ntawm daim ntawv thiab luam tawm.

b. Agricultural thiab Horticultural Products:

• HPMC yog siv nyob rau hauv kev ua liaj ua teb formulations xws li noob txheej, chiv, thiab tshuaj tua kab los txhim kho adhesion, dispersion, thiab ua tau zoo.
• Nws kuj tseem ua hauj lwm hauv cov khoom siv horticultural xws li av txias, mulches, thiab cog kev loj hlob regulators rau nws cov dej tuav thiab av hloov khoom.
