HydroxyPropyl methylcellose (HPMC) inzvimbo yezvinhu zvose inoshandiswa zvakanyanya mumaindasitiri akadai se mishonga yemishonga, chikafu, uye kuvaka. Maitiro ayo anosiyana anoenderana nemakirindi ayo, ayo akasiyana mu parameter akadai se viscosity, dhigirii rekutsiva, chizvarwa chehukuru, uye kuchena. Kunzwisisa kuti aya mamakisi anokanganisa sei kuita kwakakosha kuti gadzirise kushandiswa kwayo mune dzakasiyana siyana.
1. Viscosity
Viscosity inzvimbo yakaoma iyo inokoshesa zvakanyanya kuita kweHPMC mune dzakasiyana zvikumbiro. Izvo zvinowanzo kuyerwa mumasenti (CP) uye inogona kubva kure kure zvakanyanya kusvika kumusoro.
Pharmaceuticals: Muchipatara mafomu, semuenzaniso, 5-50 CP) inowanzoshandiswa seyakagadzirwa nekuti inopa zvinhu zvakaringana pasina zvinokanganisa zvakanyanya nguva yekubatira piritsi. Yakakwira-viscosity HPMC (semuenzaniso, 1000-00-00000 CP), kune rumwe rutivi, inoshandiswa mukudzorwa-kusunungura mafomu ekuburitswa. Iyo yepamusoro viscosity inononoka kuburitsa zvinodhaka, nekudaro inowedzera kushanda kwebope.
Kuvaka: Muzvikamu-zvakavakirwa-zvigadzirwa, pakati pekakwirira-viscosity HPMC (semuenzaniso, 100-200,000 CP) inoshandiswa kusimudzira kuchengetwa kwemvura uye kushanda. Yakakwira viscosity mamakisi anopa kudzokorora kwemvura nekuvandudza kusimba uye kusimba kwemusanganiswa, kuita kuti vakwanise kuve vakanakira tile anomhara uye mongwe.
2. Degree rekutsiva
Dhigirii rekutsiva Uku kushandurwa kunoshandura iyo solubility, gelation, uye inopisa zvivakwa zveHPMC.
Solubility: Yakakwira DS tsika kazhinji inowedzera mvura solubility yemvura. Semuenzaniso, HPMC ine nzira yakakwira ichipinda zvakanyanya mumvura inotonhora, iyo inobatsira mumishonga yemishonga uye masimba panokurumidza kupenga kunokosha.
Thermal Gelation: Iyo DS zvakare inokanganisa tembiricha yegungwa. HPMC ine dhigiri rakakwira rekutsiva rinowanzoita guls pane yakadzika tembiricha, iyo inobatsira pakudya kwekudya uko inogona kushandiswa kugadzira matanda ekupisa-akagadzikana. Mukupesana, kuderera DS HPMC inoshandiswa mune zvekushandisa inoda kukwirisa yakakwira yekudzika.
3.
Particle saizi kugoverwa inokanganisa huwandu hwekunyungudika uye zvinhu zvemuviri zvechigadzirwa chekupedzisira.
Pharmaceuticals: zvidiki zvidiki zvidiki size Hpmc ichipaza nekukurumidza, ichiita kuti iite yakakodzera yekukurumidza-kuburitswa. Kukurukurirana, saizi dzakakura dzechikamu dzinoshandiswa mumapiritsi ekudzorwa-ekusimudzira, uko kushungurudzika zvishoma kunodiwa kuburitswa kwezvinodhaka.
Kuvaka: Muzvivakwa zvekushandisa, zvidimbu zveHPMC kuvandudza homogeneity uye kugadzikana kwemusanganiswa. Izvi zvakakosha kuti uve nechokwadi cheyunifomu yekuenderana nemapendi, majasi, uye anomisheni.
4. Kuchena
Kuchena kweHPMC, kunyanya nezve kuvapo kwekusvibiswa simbi dzinorema uye zvakasara sol sol sol sol sol sol sol sol sol sol sol sol, kunyanya mumishonga yemishonga uye zvekudya zvekudya.
Pharmaceuticals uye chikafu: Yakakwirira-yekuchenera mamakisi eHPMC yakakosha kusangana nematanho ekudzokorora uye uve nechokwadi chekuchengetedza. Kusvibiswa kunogona kukanganisa polymer's performance uye kuisa njodzi dzehutano. Pharmaceutical-giredhi HPMC inofanirwa kutevedzera nhungamiro dzakadai sevaya vakatsanangurwa muPharmacopias (USP, EP) kune zvinosvibisa.
5. Kunyorera-kwakananga kuita
Pfektaceutical application:
Binders nevefiridzi
Kudzoreredzwa Kuburitswa: Yakakwira-viscosity HPMC Giredhi (1000-4000 CP) yakanakira kudzorwa-kuburitswa mafomu. Ivo vanoumba chipinganidzo cheGEL iyo inobatanidza kusunungurwa kwezvinodhaka.
OPHTRIMIC mhinduro: Ulra-yakakwirira-yakanyanya-yekuchena hpmc (pazasi 5 cp) inoshandiswa muziso rekudonha kupa lubrication pasina kukonzera kutsamwisa.
Indasitiri yechikafu:
Tiziges uye Stabilizer: Yakaderera kusvika pakati-viscosity HPMC Giredhi (5-1000 CP) inoshandiswa kudzikisira uye kusimbisa zvigadzirwa zvekudya. Ivo vanovandudza masaga uye pasherufu-hupenyu hwemasuru, zvipfeko, uye zvinhu zvinobaya.
Dietary Fiber: HPMC ine yakakwira viscosity inoshandiswa seye fiber inowedzera mune yakaderera-calorie chikafu, ichipa yakawanda uye kubatsira kugaya.
Indasitiri yekuvaka:
SEMENT uye Gypsum Zvigadzirwa Zvekare: Pakati Peko-viscosity HPMC Giredhi (100-200,000 CP) vanoshandirwa kugeza kuchengetwa kwemvura, kushanda, uye kuderedza. Izvi zvakakosha mukushandisa senge tsile adhesives, inopa, uye plasters.
Pendi uye maCoatings: HPMC mamakisi ane ruzivo rwakakodzera uye sizeza saizi inosimudzira rheology, kugadzikana, kutungamira kupedza kupedza uye nguva refu yerubu.
Mavara akasiyana eHPMC anopa huwandu hwakawanda hwezvivakwa izvo zvinogona kugadziriswa kune izvo zvinodikanwa muindasitiri akasiyana siyana. Sarudzo yeGiredhi-yakavakirwa pane viscosity, degree rekutsiva, size saizi, uye kuchenesa-inotamba chinzvimbo chakakosha mukuita basa rekuita basa raunoda. Nokunzwisisa izvi nuances, vagadziri vanogona kusarudza zviri nani HPMC giredhi reHPMC kuti vazadzise mhedzisiro, ingave iri mumishonga yemishonga, chikafu, kana kuvaka. Iyi nzira yakagadziridzwa inovimbisa kushanda kwechigadzirwa, kuchengetedzeka, uye hunhu, zvichiratidza zvinowanika uye kukosha kweHPMC mune maindasitiri ekushandisa.
