Hydroxypropyl methylcellulose (HPMC) inotorwa kubva ku cellulose uye inoshandiswa zvakanyanya mumaindasitiri akasiyana nekuda kwekusiyana kwayo.Ndiyo nonionic cellulose ether inowanikwa nekugadzirisa mamorekuru e cellulose ane propylene oxide uye methyl chloride.HPMC inowanzotengeswa muhupfu uye inonyunguduka mumvura kuti iite yakajeka, isina ruvara, viscous solution.
Iwo ekutanga zvivakwa zveHPMC akasiyana uye anobatsira mune akawanda maapplication.Zvimwe zvezvimiro zvayo zvinonyanya kukosha zvinosanganisira maitiro ekuchengetedza mvura, kukora uye kugadzira firimu.HPMC zvakare iri mukomboni wakasimba kwazvo usinga shatise nyore nekuda kwekupisa kana kuchembera.
Chimwe chezvinhu zvakakosha zveHPMC kugona kwayo kuchengetedza mamorekuru emvura.Zvimiro zvayo zvekuchengetedza mvura zvakakosha mumhando dzakasiyana dzekushandisa, kunyanya mukuvaka nekuvaka.Kana yawedzerwa kusimende kana zvimwe zvinhu zvekuvaka, HPMC inogona kudzikamisa nzira yekuomesa, ichidzivirira kuti isanyanya kuoma uye brittle nekukurumidza.Nekuchengetedza mamorekuru emvura, HPMC inosimudzira kurapwa kwakaringana uye hydration, nekudaro ichiwedzera kusimba uye kusimba kwechigadzirwa chakapedzwa.
Chimwe chinhu chakakosha cheHPMC kugona kwayo kukora.HPMC inokora zvinwiwa nekugadzira gel network kana yanyungudutswa mumvura.Kukora kwakakosha mumaindasitiri mazhinji anoda chaiwo viscosity mazinga ezvigadzirwa.Semuyenzaniso, muindasitiri yechikafu, HPMC inoshandiswa seyakakora mumiriri mumasosi uye mapfekero kuvandudza magadzirirwo avo uye kusimba.Muindasitiri yemishonga, HPMC inoshandiswa sebhainda mukugadzirwa kwemapiritsi kuti ivandudze kubatana kwavo uye kuparara kwezvivakwa.
HPMC zvakare inyanzvi yekugadzira firimu.Kana yakanyungudutswa mumvura, inogona kuumba firimu rakaonda, rakajeka, rinoshanduka.Iyo firimu-kugadzira kugona kweHPMC inoita kuti ive chinhu chakanakira kugadzirwa kweyemuromo yakasimba dosage mafomu uye transdermal zvigamba.Iyo firimu-kugadzira zvimiro zveHPMC zvinobatsira kuvandudza kunyudzwa kwezvinodhaka nekupa chipingamupinyi pakati pemushonga nenharaunda.
Pamusoro pekuchengetedza mvura, kukora uye kugadzira mafirimu, HPMC ine zvimwe zvinodiwa.Semuenzaniso, HPMC inoratidza yakanaka rheological properties, zvichireva kuti inogona kushandiswa kudzora kuyerera uye viscosity yezvinwiwa.Kukwanisa kwayo kusungirirwa kwepamusoro kunoita kuti ikwanise kusunga zvimedu uye sediments mumhinduro, zvichiita kuti ibudirire mukugadzirwa kwekumiswa.
HPMC inzvimbo yakagadzikana ine yakanaka yekupisa uye kuramba kuchembera.Haiite nezvimwe zvinhu, zvichiita kuti ienderane nezvinhu zvakawanda zvakasiyana.Kugadzikana kwayo kunoitawo kuti ive yakakodzera kushandiswa mune zvigadzirwa zvinoda hupenyu hurefu hwesherufu.
HPMC inoshandiswa mumaindasitiri mazhinji, anosanganisira kuvaka, mishonga, zvigadzirwa zvekuchengeta munhu, chikafu uye zvizorwa.Mukuvaka, inoshandiswa sechinhu chekuchengetedza mvura mune simenti, kongiri uye dhaka kuti ivandudze kushanda uye kuisa nguva.Mumishonga, HPMC inoshandiswa sebhainda, disintegrant, uye inodzorwa kuburitsa mumiriri mukuumbwa kwehwendefa.Inoshandiswawo seye viscosity modifier mune ophthalmic solutions.
Muindasitiri yekuchengeta wega, HPMC inoshandiswa seyakakora mumiriri mumashampoos, lotions uye zvimwe zvigadzirwa zverunako kuvandudza manyorerwo uye viscosity.Inoshandiswawo semugadziri wekugadzira firimu mune zvekuzora kubatsira kuvandudza kugovaniswa kwepigment uye kudzivirira clumping.
Muindasitiri yechikafu, HPMC inoshandiswa seyakakora, emulsifier uye stabilizer muzvigadzirwa zvakaita sezvigadzirwa zvemukaka, soups uye zvinwiwa.HPMC inoshandiswawo seyekuputira uye firimu-inogadzira mumiriri mumichero, muriwo uye zvihwitsi zvekupfeka.
HPMC mukomboni unosiyana-siyana une zvinhu zvakawanda zvinodikanwa sekuchengetedza mvura, kukora, uye kugadzira firimu.Nekuda kwezvivakwa zvayo zvakasiyana, inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kusanganisira kuvaka, mishonga, zvigadzirwa zvekuchengeta munhu, chikafu uye zvizorwa.HPMC ikamu rakagadzikana kwazvo risingaite nezvimwe zvinhu, zvichiita kuti ienderane nezvakawanda zvakasiyana zvigadzirwa.Naizvozvo, HPMC ine huwandu hwakasiyana hwekugona maapplication uye yakafara tarisiro mumaindasitiri akasiyana.
