Hydroxyprupyl methylcellose (HPMC)

HydroxyPropyl methylcellose (HPMC), anozivikanwawo seHyprollose, inzvimbo yezvinhu zvakasiyana-siyana kubva ku cellulose. Iyo inoshandiswa zvakanyanya mumagiratsiri akasiyana siyana nezvenzvimbo dzaro dzakasiyana, kusanganisira mishonga, kuvaka, chikafu, zvizoro, uye hanya. Mukutungamira uku kwakazara, isu tichaongorora chimiro chemakemikari, zvivakwa, maitiro ekugadzira, zvinoshandiswa, uye zvakanaka zveHPMC zvakadzama.

1. Nhanganyaya kuHPMC:

HydroxyPropyl methylcellose (HPMC) ndeye isiri-ionic cellulose ether inotorwa kubva kune yakasikwa cellulose kuburikidza nemakemikari yekugadziridzwa. Iyo yakashongedzwa nekurapa cellulose ine proculene oxide uye methyl chloride yekuunza hydroxyprospropropropropropropropyl uye methyl mapoka kune iyo cellulose backbone. Iyo polymer inokonzeresa inoratidza huwandu hwenzvimbo dzinoita kuti ive yakakosha kwazvo mune dzakasiyana siyana maindasitiri.

2. Chemical chimiro uye zvivakwa:

HPMC inoonekwa nemakemikari ayo emakemikari, ayo ane cellulose backbone aine hydroxypruppropyl uye methyl exkritue akasungirirwa kumapoka eHydroxyl. Dhigirii rekutsiva

Zvivakwa zveHPMC zvinokurudzirwa nezvinhu zvakadai senge zvinyoro-nyoro uremu, degree rekutsiva, uye hydroxypruppropyl / methyl ratio. Kazhinji, HPMC inoratidzira iyo inotevera kiyi zvivakwa:

• Mvura-Solubility
• Firimu-inogadzira kugona
• Kuremedza uye gelling zvivakwa
• SOPECION SEIP
• Kugadzikana pamusoro peiyo pl red ph range
• Kuenderana nezvimwe zvinhu

3. Kugadzira maitiro:

Kugadzirwa kweHPMC kunosanganisira matanho akati wandei, kusanganisira:

1. Kugadzirira kweCellulose: Natural Cellulose, kazhinji inotwasuka kubva kune huni prophop kana machira, anonatswa uye akanatswa kubvisa tsvina uye lignin.
2. Eteraifitifitifiti yekuita: cellulose inobatwa ne processyxo oxide uye methyl chloride pamberi peAlkali CATALYSS
3. Kusarerekera uye kugeza: Chigadzirwa chinokonzeresa chakarerekera kubvisa yakawandisa Alkali uye yakabva yageza kuti ibvise ne-zvigadzirwa uye kusvibiswa.
4. Kuomesa uye kugeda: Iyo yakanatswa HPMC yakaomeswa uye pasi kuita hupfumi hweupfu hwakakodzera kushandiswa kwakasiyana siyana.

4. Mamakisi uye zvakatemwa:

HPMC inowanikwa mumakiromita ehuremu uye kutaurwa kuti usangane nezvinodiwa zvemaindasitiri akasiyana uye zvinoshandiswa. Izvi zvinosanganisira misiyano mu viscosity, chidimbu chemberi, dhigirii rekutsiva, uye tembiricha yegungwa. Makiromita akajairika eHPMC anosanganisira:

• Standard viscosity mamakisi (semuenzaniso, 4000 cps, 6000 CPS)
• Yakakwira viscosity mamakisi (semuenzaniso, 15000 CPs, 20000 CPS)
• Yakadzika viscosity mamakisi (semuenzaniso, 1000 CPs, 2000 CPs)
• Yakanzwisisika mamakisi ezvinyoreso zvikumbiro (semuenzaniso, kusunungurwa kusunungurwa, kusunungurwa kwakadzorwa)

5. Zvikumbiro zveHPMC:

HPMC inowana yakashandiswa yakapararira muindasitiri akasiyana siyana nekuda kwezvivakwa zvaro zvinoitika uye zvinoenderana nezvinhu zvakasiyana. Zvimwe zvezvinhu zvakakosha zveHPMC zvinosanganisira:

a. Indasitiri yeMishonga:

• Tablet uye Capsule Coatings
• Inodzorwa kuburitswa mafomu
• Binders uye disintegrants mumahwendefa
• Ophthalmic mhinduro uye kumiswa
• Nzvimbo dzepamusoro dzakadai semakiromita uye oiri

b. Indasitiri yekuvaka:

• Simende uye gypsum-based zvigadzirwa (semuenzaniso, monganda, plasters)
• Tiles inonamira uye grouts
• Kunze kwekunzwa uye kupedzisa masisitimu (eifs)
• Kuzvimanikidza kuzvimiririra
• Pendi-dzakavakirwa mvura pendi uye hukuru

c. Indasitiri yechikafu:

• Kuremedza uye kusimbisa mumiririri mune zvigadzirwa zvekudya
• Emulsifier uye kumisa mumiririri mune sosi uye kupfeka
• Dietary Filer Supplements
• Gluten-Yemahara Kubheka uye Confectionery

d. Kuchengeta Kwemunhu uye Cosmetics:

• Thickener uye kumhanyisa mumiririri mumhando uye mafiresi
• Binder uye firimu-yaimbova muzvikwereti zvekuchengeta
• Kudzoserwa Kuburitswa muGandacare mafomu
• Ziso rinodonha uye kubata lens mhinduro mhinduro

6. Zvakanakira kushandisa HPMC:

Iko kushandiswa kweHPMC kunopa akati wandei kubatsirwa kwemaindasitiri akasiyana:

• Kuvandudzwa kwechigadzirwa kuita uye mhando
• Yakavandudzwa Kuumbika Kuchinjika uye Kugadzikana
• Yakawedzera mararamiro uye yakaderedzwa apiilage
• Yakagadziriswa maitiro ekubudirira uye mutengo-kushanda
• Kuteerana nezvinodzora zvinodiwa uye kuchengetedza zviyero
• Zvakatipoteredza hushamwari uye biocompable

7. Zvizama zvenguva yemberi uye maonero:

Iko kudiwa kweHPMC kunotarisirwa kuenderera mberi nekukura, kuitiswa nezvinhu zvakadai sekuwedzera kwemaguta, kukura kwezvivakwa, uye kudiwa kwezvinhu zvechinangwa uye zvoga zvekutarisira. Kuenderera mberi kwekutsvaga uye kusimudzira kuedza kwakanangidzirwa pane inowedzera hpmc mafomu, kuwedzera mashandisiro ayo, uye kugadzirisa maitiro ekugadzira kuti usangane nezvokubuda mumusika.

8. Mhedziso:

HydroxyPropyl methylcellose (HPMC) inzira inoverengeka ine manyoreresa ekushandisa maindasitiri akawanda. Zvivakwa zvaro zvakasarudzika, zvakadai sekusarudzika kwemvura, kugona kwemafirimu ekugadzira, uye zvakabatikana, zvinoita kuti ive yakakosha mumishonga, kuvaka, chikafu, chokudya, uye cosmetics. Semunhu tekinoroji inofambira mberi uye musika inoda kusvika, HPMC inotarisirwa kutamba chiitiko chinowedzera chakakosha mukuumba ramangwana renguruve dzakasiyana siyana.
