Hydroxypropyl methylcellulose (HPMC) i polymer inoshanda zvakasiyana-siyana inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nekuda kwekusiyana kwayo uye mabasa. Iyi semi-synthetic polymer inotorwa kubva kune cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. HPMC inogadzirwa nekugadzirisa cellulose kuburikidza ne etherification yepropylene oxide uye methyl chloride. Iyo inoguma polymer inoratidza huwandu hwezvinhu zvinodikanwa, zvichiita kuti ive yakakodzera kune akasiyana maapplication. Izvi zvakasiyana-siyana zvekushandisa zvinogona kuverengerwa kugona kwayo kugadzira firimu, kukora zvivakwa, kugadzikana munzvimbo dzakasiyana uye biocompatibility.
1. Indasitiri yemishonga
A. Oral administration:
Kuburitswa Kunodzorwa: HPMC inowanzoshandiswa kudzora kuburitswa kwezvinodhaka mukugadzirwa kwemishonga. Iyo inoumba matrix yakagadzikana inobvumira kudzorwa kusunungurwa kwemishonga kwenguva yakareba, nokudaro kuvandudza kushanda kwekurapa uye kutevedzera murwere.

Suspension Agent: Mune zvinwiwa dosage mafomu, HPMC inoshanda senge inomisa mumiriri, ichidzivirira zvimedu kubva pakugadzirisa uye kuve nechokwadi chekugovera yunifomu yemushonga.
B. Ophthalmic applications:
Viscosity Modifier: HPMC inoshandiswa kugadzirisa viscosity yemadonhwe eziso kuti ipe mafuta ekuzora uye kuve nechokwadi chenguva refu yekubata paziso reziso.
Vagadziri vemafirimu: aishandiswa kugadzira masiki emaziso kana kuisirwa kuburitswa kwemishonga muziso.
C. Misoro yegadziriro:
Gel Formation: HPMC inoshandiswa kugadzirira topical gels inopa yakatsetseka, isina-greasy manyorerwo uye inovandudza kuterera kwemurwere.
Skin patch adhesives: Mu transdermal drug delivery systems, HPMC inopa adhesive zvivakwa uye inodzora kuburitswa kwemishonga kuburikidza neganda.
D. Biodegradable Implants:
Scaffold zvinhu: HPMC inoshandiswa kugadzira biodegradable implants inodzora kuburitswa kwemishonga mumuviri, kubvisa kudiwa kwekuvhiyiwa.
2. Indasitiri yekuvaka
A. Tile Adhesive:
Thickener: HPMC inoshandiswa seyakakora mumatairi anonamira kuti ipe kuenderana kunodiwa kwekushandisa nyore.
Kuchengeta Mvura: Inosimudzira kuchengetwa kwemvura kweanonamira, ichidzivirira kubva pakuoma nekukasira uye kuve nechokwadi chekurapa kwakakodzera.
B. Simende dhaka:
Kushanda: HPMC inoshanda seye rheology modifier kudzivirira kupatsanurwa uye kuwedzera hukama, nekudaro ichivandudza kushanda kwesamende-based mortars.
Kuchengeta Mvura: Zvakafanana nekunamira kwetairi, inobatsira kuchengetedza unyoro mumusanganiswa wesimenti, zvichibvumira hydration yakakodzera uye kukura kwesimba.
3. indasitiri yezvekudya
A. Zvekuwedzera zvekudya:
Thickeners uye Stabilizers: HPMC inoshandiswa seyakakora uye inodzikamisa mune zvakasiyana-siyana zvechikafu zvigadzirwa, senge sosi, madhirezi uye madhiri.
Mafuta anotsiva: Muchikafu chakaderera-mafuta kana chisina-mafuta, HPMC inogona kushandiswa sechinotsiva mafuta kuti uwedzere kunaka uye muromo.
4. Cosmetics industry
A. Zvigadzirwa zvekuchengeta:
Viscosity Kudzora: HPMC inoshandiswa mukushongedza zvizorwa senge lotions uye makirimu kudzora viscosity uye kunatsiridza kuumbwa kwese.
Vagadziri vemafirimu: Batsira kugadzira firimu mune zvigadzirwa zvekuchengeta bvudzi, zvichipa danda rekudzivirira.
5. Mamwe maapplication
A. Ingi yekudhinda:
Thickener: HPMC inoshandiswa seyakakora mumvura-inodhinda ingi kuti ibatsire kuwana kuenderana kunodiwa uye kugadzikana kweinki.
B. Adhesive products:
Kuvandudza viscosity: Mune anonamira maumbirwo, HPMC inogona kuwedzerwa kuwedzera viscosity uye kunatsiridza bonding zvivakwa.
5. mukupedzisa
Izvo zvakasiyana-siyana zvekushandisa zveHPMC mumaindasitiri akasiyana-siyana zvinoratidzira kuita kwayo uye kuita kwayo. Kushandiswa kwayo mumishonga, kuvaka, chikafu, zvizorwa uye mamwe minda inoratidza kusanganisa kwayo kwakasarudzika kwezvivakwa, kusanganisira kugona kugadzira firimu, kukora zvivakwa uye kugadzikana. Sezvo tekinoroji netsvagiridzo zvichifambira mberi, HPMC ingangoramba ichiita basa rakakosha mukuvandudza zvigadzirwa zvehunyanzvi uye magadzirirwo muzvikamu zvakasiyana.
