Hydroxypropylmethylcylosellose (HPMC) ishandare yakati wandei inoshandiswa zvakanyanya mumagirendi akasiyana siyana nekuda kwezvivakwa zvaro zvakasarudzika. Iyi compound ndeyekuti inobviswa kwe cellulose, polymer yakasikwa inowanikwa mumasango masero emadziro. The synthesis of HPMC involves treating cellulose with propylene oxide to introduce hydroxypropyl groups and with methyl chloride to introduce methyl groups. Iyo polymer inobvumirwa inoratidza huwandu hwakawanda hwepamoyo uye makemikari zvivakwa, zvichiita kuti zvive zvakakodzera kushandiswa mumishonga yemishonga, kuvaka, chikafu uye mamwe maindasitiri.
1.comemical chimiro uye kuumbwa:
Hydroxyprishpyl methylcellose ndeye semi-synthetic polymer ine yakaoma kemikari chimiro. Iyo polymer's babobone ine cellulose, mutsara wenziyo yemizasi mamorekuru akabatanidzwa ne β -,4-glycosic zvisungo. Iyo hydroxyprupropyl boka rinounzwa nekutsiva iyo hydroxyl boka (-Oh) neboka repropitori, uye boka remethyl rinounzwa nenzira yakafanana. Dhigirii rekutsiva
2. Solubility:
Imwe yezvinhu zvakasarudzika zveHPMC ndeyekunyepedzera kwayo. Izvo zvinonyangadza mumvura inotonhora uye inopisa uye inopa zvakanakira zvakanaka mune dzakasiyana siyana dzekushandisa. Solubility inogona kugadziridzwa nekugadzirisa iyo degree rekutsiva uye smecular uremu hwe polymer. Ichi chivakwa chinoita HPMC yakanakisa mumiriri wekudzorwa
3. Viscosity:
HydroxyPropyl methylcellose inowanikwa mune dzakasiyana siyana dze viscosity mazinga, zvichienderana nezvinhu zvakaita sehuremu hwemanyorerwe, degree rekutsiva, uye mhinduro yekutsiva. Iyo viscosity yeHPMC Solutions inovatendera kuti ishandiswe mune akawanda maindasitiri ekushandisa, kusanganisira mishonga mishonga, sehana mumvura madhiri emvura, uye seyakagadzirwa mafirimu ekugadzira mafirimu emberi.
4. Firimu-fomu rekugadzira:
Kugona kwefirimu-kugadzirwa kweHPMC kwakadzorerwa mune zvekushandisa senge zvezvinodhaka, uko kwashandiswa kupa gadziriro yekudzivirira yekuvhara mishonga, kudzora kusunungurwa kwezvinodhaka, uye kuvandudza kugadzikana. HPMC mafirimu akajeka uye anoshanduka, uye zvivakwa zvavo zvinogona kugadziriswa nekugadzirisa polymer conlymer, inorema uremu uye yepamhepo.
5. Maitiro ekuuraya:
Hydroxyprishpyl methylcellestulose inoratidzira yakanaka yekugadzira iyo yekugadzikana mukati meiyo chaiyo tembiricha. Zvivakwa zvekupisa zvinokanganiswa nezvinhu zvakadai sedanho rekutsiva, zvinyoro-nyoro uremu, uye kuvapo kwePlanticzeders. Izvi zvivakwa zvinoita kuti HPMC yakakodzera kune zvinoshandiswa zvekushandisa apo iyo yekunyora kugadzikana ndeyekutsoropodza, senge kugadzirira kwekupisa-kupisa mishonga yemishonga.
6. Biocompriility:
Mune minda yemishonga uye biomicalical, biocomprible kufunga kwakakosha kwezvinhu zvinoshandiswa mukutumira zvinodhaka. Hydroxypruppropyl methylcellose inowanzoonekwa yakachengeteka uye ine yakanaka biocomputer. Iyo inoshandiswa zvakanyanya mukuumbwa kwemifananidzo yemuromo, mhinduro dzeOPHTRIMIC
7. Kuchengetwa kwemvura uye zvakakora zvivakwa:
Hpmc's kugona kuchengetedza mvura uye makompiro emamiriro ezvinhu kunoita kuti ive yakakosha mune zvekuvaka zvakadai seyakagadzirwa-based zvigadzirwa. Mune izvi zvekushandisa, HPMC zviito semvura inochengetedza mumiririri, kuvandudza maitiro uye kudzivirira kuomarara kwekusagadzikana kwezvinyorwa. Kukora midziyo zvakare inoshandiswawo mune akasiyana siyana zvigadzirwa zvekudya kuti uwedzere kugadzirwa uye muromo.
8. Kudzoserwa-Kuburitswa Kurovera zvinodhaka:
Chimwe chezvakakosha zvekushandisa zvehydroxyprupyl methylcellose iri muchimiro chekudzorwa-kusunungura zvinodhaka zvinodhaka. Iyo Polymer's Solubility, viscosity, uye mafirimu-ekuumba midziyo inofambisa kudzorwa kwekusunungurwa kwemishonga, inogonesa yakasimbiswa uye yakatarisana nekukwezva zvinodhaka. Izvi zvinonyanya kubatsira pakuvandudza kutevedzera kwemurwere uye kuderedza mhedzisiro inosanganiswa nekukurumidzwa kwezvinodhaka.
9. Kugadzikana pasi peakasiyana phvie:
HPMC inoratidza kugadzikana pamusoro peyakafara pH range, ichiita kuti iite kuti iyo nzira inoda kugadzikana pasi pe acidic kana alkaline mamiriro. Ichi chivakwa chinobatsira mu mishonga yemishonga nekuti zvinodhaka zvekufungidzira zvinogona kusangana zvakasiyana pP nharaunda mune gastrointestinal turakiti.
10. Rheological Properties:
Maitiro ekunyepedzera eHPMC anokosha ekushandisa zvirimo zvinoyerera zvivakwa zvakashata, zvakadai sekugadzirira kwejasi, zvinonamatira uye geri. Iyo rheological zvivakwa inogona kuve yakagadziriswa nekugadzirisa iyo kusunganidzwa uye smecular uremu hweHPMC kuti uwane maitiro ekuyerera anodiwa e-kutonga.
HydroxyPropyl methylcellose yave polymer isingabvumirwe mune dzakasiyana maindasitiri nekuda kwesanganiswa yayo yakasarudzika yekusanganisa, viscosity, firimu rekugadzira uye biocomputer. Kuita kwayo kunoita kuti zviite zvakakodzera kune dzakasiyana-siyana zvikumbiro, kubva pamishonga yemishonga uye zvigadzirwa zvekuvaka kune chikafu uye cosmetics. Sezvo vaongorori vanoramba vachiongorora mafomu matsva uye zvinyorwa zvehydroxyprupproplesel
