Hypromellose uye HPMC (hydroxypropyl methylcellulose) zvechokwadi musanganiswa wakafanana, kunyangwe uchizivikanwa nemazita akasiyana. Mazwi ese ari maviri anoshandiswa zvichichinjika kureva musanganiswa wemakemikari unowana mashandisirwo akawandisa mumaindasitiri akasiyana, anosanganisira emishonga, chikafu, zvekuzora, uye kuvaka.
Chemical Structure:
Hypromellose: Iyi isemi-synthetic, inert, viscoelastic polymer inotorwa kubva ku cellulose. Ikemikari inoumbwa ne cellulose yakagadziridzwa ne hydroxypropyl uye methyl mapoka. Aya magadzirirwo anowedzera kunyungudika kwayo, viscosity, uye zvimwe zvinodikanwa zvivakwa kune akasiyana maapplication.
HPMC (Hydroxypropyl Methylcellulose): Uyu musanganiswa wakafanana nehypromellose. HPMC ndiyo acronym inoshandiswa kureva komisheni iyi, inomiririra chimiro chayo chemakemikari inosanganisira hydroxypropyl uye methyl cellulose mapoka.
Properties:
Solubility: Zvese zviri zviviri hypromellose uye HPMC zvinonyungudika mumvura uye organic zvinonyungudutsa, zvichienderana nehuwandu hwekutsiva uye huremu hwepolymer.
Viscosity: Aya mapolymer anoratidza kuwanda kwemaviscosity zvichienderana nehuremu hwawo hwemamorekuru uye dhigirii rekutsiva. Inogona kushandiswa kudzora viscosity yezvigadziriso uye kuvandudza kugadzikana kwemaitiro mumhando dzakasiyana dzekushandisa.
Firimu Kugadzira: Hypromellose / HPMC inogona kuumba mafirimu kana akakandwa kubva kune mhinduro, ichiita kuti ave akakosha mumishonga yekuputira maapplication, kwaanogona kupa inodzorwa kuburitsa zvivakwa kana kuchengetedza zvinoshanda kubva kune zvakatipoteredza zvinhu.
Thickening Agent: Ose ari maviri hypromellose neHPMC anowanzo shandiswa seanokora muzvigadzirwa zvakasiyana siyana, kusanganisira chikafu, zvizorwa, nemishonga. Vanopa hunyoro hunyoro uye vanovandudza kugadzikana kwe emulsions uye suspensions.
Applications:
Pharmaceuticals: Muindasitiri yemishonga, hypromellose/HPMC inoshandiswa zvakanyanya sechinhu chinobatsira mumuromo yakasimba dosage mafomu akadai semapiritsi, capsules, uye granules. Inoshanda akasiyana siyana senge binder, disintegrant, uye inodzorwa-kuburitsa mumiririri.
Indasitiri yeChikafu: Hypromellose/HPMC inoshandiswa muindasitiri yechikafu seyakakora, emulsifier, uye inodzikamisa muzvigadzirwa zvakaita sesosi, madhirezi, uye zvinhu zvekubheka. Inogona kuvandudza magadzirirwo, viscosity, uye sherufu-hupenyu hwezvigadzirwa zvekudya.
Cosmetics: Muzvizoro, hypromellose/HPMC inoshandiswa mukugadzira makirimu, lotions, uye gels kupa viscosity control, emulsification, uye mwando kuchengetedza zvivakwa.
Kuvaka: Muzvivakwa zvekuvaka, hypromellose/HPMC inoshandiswa seyakakora uye yekuchengeta mvura muzvigadzirwa zvine simende senge madhiraivha anonamira, dhaka, uye renders.
hypromellose uye HPMC inoreva kune imwecheteyo musanganiswa-inobva cellulose yakagadziridzwa nehydroxypropyl uye methyl mapoka. Vanoratidza zvivakwa zvakafanana uye vanowana maapplication akasiyana-siyana mumaindasitiri anosanganisira emishonga, chikafu, zvekuzora, uye kuvaka. Kuchinjana kwemazwi aya dzimwe nguva kunogona kukonzeresa nyonganiso, asi anomiririra imwechete inosiyana-siyana polymer ine kushandiswa kwakasiyana.
