Hydroxypropyl methylcellulose (HPMC) ipolymer inoshandiswa zvakasiyana-siyana inoshandiswa mumaindasitiri akasiyana siyana, anosanganisira mishonga, kuvaka, chikafu, uye zvekuzora.Imwe kiyi pfuma inokanganisa zvakanyanya kukodzera kwayo ndeye viscosity.Viscosity inoreva kuramba kwemvura kuyerera uye inoita basa rakakosha mukuona mashandiro uye kushanda kweHPMC mumashandisirwo akasiyana.
1. Nzwisisa HPMC:
Hydroxypropylmethylcellulose (HPMC) inonzi semi-synthetic mvura-soluble polymer yakabva muselulosi.
Nekuda kwezvimiro zvayo zvakasiyana, inowanzoshandiswa seyakakora, stabilizer, firimu rekare uye rinonamira.
HPMC inowanikwa mumhando dzakasiyana-siyana, imwe neimwe iine mazinga akasiyana e viscosity, ayo anokanganisa kuita kwayo mumashandisirwo akasiyana.
2.Pharmaceutical applications:
Muchikamu chemishonga, HPMC inoshandiswa zvakanyanya mumachira emapiritsi, akadzora kuburitswa maumbirwo uye kumiswa.
Viscosity inobata basa rakakosha mukudzora ukobvu uye kufanana kwepiritsi coating, kuve nechokwadi chekuburitswa kwezvinodhaka kwakaringana uye bioavailability.
Iyo viscosity yeHPMC inokanganisawo mafambiro ekuyerera kwekumiswa uye kugadzikana kwekugadzirisa, nekudaro kukanganisa kuendeswa kwezvinodhaka uye kutevedzera murwere.
3.Indasitiri yekuvaka:
HPMC inoshandiswa zvakanyanya muindastiri yekuvaka semushonga wekukora wemasimende-based madhaka, mataira anonamira uye plasters.
Viscosity inokanganisa kushanda uye sag kuramba kwedhaka maumbirwo, kuve nechokwadi chekunamatira kwakaringana uye kudzikisa tsvina yezvinhu panguva yekuvaka.
Nekugadzirisa iyo viscosity yeHPMC maumbirwo, vavaki vanogona kuwana inodiwa kuenderana uye maitiro ekuita, nekudaro vachivandudza huwandu hwese hwemapurojekiti avo ekuvaka.
4. Indasitiri yezvekudya nezvinwiwa:
Muindasitiri yechikafu nechinwiwa, HPMC inoshandiswa seyakakora, emulsifier uye stabilizer mune zvakasiyana siyana zvigadzirwa zvinosanganisira sosi, soups uye dairy dzimwe nzira.
Viscosity inokanganisa manyorerwo, muromo uye kugadzikana kwechikafu, kuve nechokwadi chezvakanaka zvekunzwa zvivakwa uye hupenyu hwesherufu.
Vagadziri vechikafu vanonyatso sarudza HPMC mamakisi ane chaiwo viscosity mazinga kuti awane chinodiwa chigadzirwa kuenderana uye kugadzirisa zvinodiwa.
5. Zvizora uye zvigadzirwa zvekuchengeta munhu:
HPMC inoshandiswa seyakakora uye kugadzira firimu mumiriri mune zvekuzora uye zvigadzirwa zvekuchengeta zvega zvakaita semafuta, lotions uye shampoos.
Viscosity inoita basa rakakosha mukudzora kuenderana kwechigadzirwa, kupararira uye kugadzikana, kuwedzera ruzivo rwemushandisi uye kuita kwechigadzirwa.
Cosmetic formulators vanovimba neHPMC ine yakagadziridzwa viscosity profiles kuti iwane inodiwa rheology uye hunhu hwekunzwa mukuumbwa kwavo.
6. Kukosha kwekudzora viscosity:
Kunyatso kudzora viscosity kwakakosha kusangana nezvinodiwa zvekushandisa kwakasiyana.
Vagadziri vanopa akasiyana siyana eHPMC mamakisi ane akasiyana viscosity mazinga, achibvumira vanogadzira kuti vasarudze giredhi rinonyatsokodzera kunyorera kwavo.
Chaiyo viscosity kuyerwa uye rheological maitiro anogonesa maformulators kukwenenzvera maumbirwo uye kuona kuenderana kwechigadzirwa kuita uye kunaka.
7. Zvinhu zvinokanganisa viscosity:
Zvinhu zvakati wandei, zvinosanganisira kusungwa kwepolymer, huremu hwemamorekuru, dhigirii rekutsiva, uye tembiricha, zvinogona kukanganisa viscosity yeHPMC mhinduro.
Kunzwisisa hukama pakati pezvinhu izvi uye viscosity kwakakosha pakugadzira zvigadzirwa zveHPMC zvine hunhu hunodiwa hwekuita.
Viscosity ndiyo yakakosha parameter iyo inogona kukanganisa zvakanyanya mashandiro uye mashandiro eHPMC mumashandisirwo akasiyana siyana.
Mune mishonga, kuvaka, chikafu, cosmetics uye maindasitiri ekuchengetedza ega, kunyatso kudzora viscosity kwakakosha kuzadzisa zvakatemwa zvekugadzira zvinodiwa uye kuzadzisa chinodiwa chigadzirwa hunhu.Nekunzwisisa kukosha kwe viscosity uye maitiro ayo paHPMC zvikumbiro, vagadziri uye vanogadzira vanogona kukwirisa maumbirwo ekuvandudza kuita kwechigadzirwa, kunaka uye kugutsikana kwevatengi.Viscosity chinhu chakakosha pakuona mashandiro uye mashandiro eHPMC mumhando dzakasiyana dzekushandisa.Kudzora kwayo nekunzwisisa kwakakosha kuti uwane hunhu hwechigadzirwa uye kuve nechokwadi chebudiriro mumaindasitiri ese.
