Hydroxypropylmethylcellose (HPMC) ishandudzi uye inopesana polymer iyo ndeya cellulose ether mhuri. Iyo yakashongedzwa kuburikidza neyekutevedzana kwemakemikari maitiro nekugadzirisa zvakasikwa cellulose, chikamu chakakosha chesango madziro emadziro. Iyo inokonzeresa HPMC ine yakasarudzika seti yezvivakwa inoita kuti ive yakakosha kune maindasitiri.
1. Chemical chimiro uye kuumbwa:
HPMC inotorwa kubva ku cellulose, iyo ine inodzokorora zvikamu zveGlucose zvakabatana ne β-3,4-glycosic zvisungo. Kuburikidza nemakemikari kugadziridzwa, hydroxyprupyl uye mapoka mapoka anounzwa muCellulose Backbone. Dhigirii rekutsiva
Chemakemi chemc inopa iyo inopa iyo solubility uye gel-yekuumba kugona, ichiita kuti ibatsire mune dzakasiyana siyana dzekushandisa maindasitiri akasiyana siyana.
2. Solubility uye rheological zvivakwa:
Chimwe chezvivakwa chisina kujairika cheHPMC is solubility mumvura, ichiigadzira iyo mvura inosemesa yemvura. HPMC inoumba yakajeka uye viscous mhinduro kana ikanyungudika mumvura, uye zvimiro zvaro zvaro zvave kugadziriswa nekuchinja nehuremu hwemanyoreri uye degree rekutsiva. Iyi tinable solubility uye rheology inoita HPMC yakakodzera kune dzakasiyana siyana dzekushandisa.
3. Firimu-fomu rekugadzira:
HPMC ine yakanakisa firimu-inoumba zvivakwa uye inogona kuumba mafirimu anochinjika kana polymer yakanyungudutswa mumvura. Ichi chivakwa chinowana application mune maindasitiri emishonga uye ezvekudya zvekubatanidza mahwendefa, achinongedza flavors uye kupa zvipfuyo zvinotyisa mumafirimu edible.
4. Zvekurapa zvikumbiro:
HPMC inozoshandiswa zvakanyanya muindasitiri yemishonga nekuda kwenhandare yayo yakawanda. Iyo inoshandiswa mukugadzira piritsi senge binder, disintegrant, firimu-inogadzira mumiririri uye yakasimbiswa-kuburitswa mumiriri. Iko kugona kwePolymer yekudzora kusunungurwa kwezvinodhaka uye kugadzirisa kugadzikana kwezvinogadzirwa zvinodhaka kunoita kuti ive yakakosha mukugadzirwa kwemhando dzakasiyana dzemuromo.
5. Indasitiri yekuvaka:
Mune indasitiri yekuvaka, HPMC inoshandiswa zvakanyanya seyemumiriri, mvura inochengetedza mumiririri uye kukwidziridzwa kune zvigadzirwa zveComent-based, grasters. Zvivakwa zvaro zvaro zvinobatsira kuvandudza kushanda, Sag kuramba uye kuderedza, uchiita kuti ive yakakosha pakuvaka.
6. Chikafu uye Cosmetics:
Muindasitiri yechikafu, HPMC inoshandiswa seanoshandiswa seanoti, emulsifieri, uye stabilizer mune akasiyana zvigadzirwa, kusanganisira sosi, comments, uye zvigadzirwa zvemukaka. Mafungiro ayo ehurumende uye kugona kuumba maGels akajeka anoita kuti zviite kuti zvibate zvekudya zvekudya.
Saizvozvo, mune yeCosmetic indasitiri, HPMC inoshandiswa mukuumbwa senge makiromita, marara, uye shampoos nekuda kwekuita kwayo, kusimbisa, uye mafirimu ekuumba okugadzira. Inobatsira kune iyo chimiro, viscosity uye kugadzikana kwezvizorodzi.
7. Pendi uye majasi:
HPMC inoshandiswa seyakakwenenzverwa uye rheology modifier mumvura-yakavakirwa pendi uye marara. Iyo inosimudzira zvivakwa zvekunyorera, zvakadai sekurapa uye kupokana nekuparadzaniswa, ukuwo kuvandudza kuita kwakazara kwekucheka.
8. Adhesive:
Mune yekuzvinamatira mafomu, HPMC inoita seyakakwenenzverwa uye mvura inochengetedza mumiririri. Kugona kwayo kudzora viscosity uye kuvandudza kudiwa kunoita kuti zviite zvakakosha mukugadzirwa kwemanamatira mumhando dzakasiyana siyana, kusanganisira huni hwekugadzira uye bepa rekubatanidza.
9. Kudzora Kuburitswa System:
Kudzoserwa kusunungurwa kwezvinhu zvinoshanda zvine basa kune maindasitiri mazhinji, kusanganisira mishonga yemishonga uye kurima. HPMC inowanzoshandiswa kugadzira masisitimu anodzorwa nekuda kwekugona kwayo kuumba matrix anodzora huwandu hwekusunungura pane imwe nzvimbo yekuwedzera nekufamba kwenguva.
10. Biomedical Zvikumbiro:
Muminda ye biomidicine uye tissue engineering, HPMC yakaongororwa kune yayo yekukonzeresa uye kugona kuumba hydroels. Iyi hydrogels inogona kushandiswa mukutumira zvinodhaka, kurapa kurapa, uye tishu rekuchengetedza mafomu.
11. Hunhu hwezvemamiriro ekunze:
HPMC inoonekwa seyakaishuvira nharaunda sezvo ichinge yatorwa kubva kune inovandudza zviwanikwa uye ndeye biodegradable. Kushandiswa kwayo mumhando dzakasiyana siyana dziri mumutsetse nekuwedzera kudiwa kwekusimudzira uye zvakatipoteredza zvinoshamisa zvinhu.
12. Zvinonetsa uye kufunga:
Kunyangwe HPMC ichishandiswa zvakanyanya, matambudziko akati wandei aripo, kusanganisira kunzwa kwayo kwekushisa, kunobata zvivakwa zvaro. Pamusoro pezvo, iyo yekunyora uye yemakemikari yekugadziridzwa kwemasero inoda kunyatsofungisisa kubva kune yemhoteredzo uye yekuchengetedza maonero.
13. Regulatory kutevedzera:
Sezvineiwo nezvinhu chero zvipi zvacho zvinoshandiswa mumishonga, chikafu uye zvimwe zvigadzirwa zvekutengesa, zvakakosha kuti zviyero zvakaiswa nemauto ekuzvidzora anoomerera. HPMC kazhinji inosangana nezvinodiwa zvekudzora, asi vagadziri vanofanirwa kuve nechokwadi chekutevedzera nhungamiro chaiyo yekunyorwa kwega kwega.
Mukupedzisa:
Hydroxypropylmethylcellose (HPMC) inzvimbo yevose polymer ine huwandu hwakawanda hwekushandisa maindasitiri akasiyana siyana. Yayo yakasarudzika yekusanganisa kweSolubility zvivakwa, kudzora kwetsitsi kuita kuti ive yakakosha mumishonga, kuvaka, chikafu, chifukidziro, pendi, anomhanyisa uye zvimwe. Maindasitiri achiramba achitsvaga mhinduro dzakasimba uye dzinobudirira, HPMC inogona kuramba iri mutambi akakosha mune dzakasiyana zvigadzirwa zvekugadzira zvigadzirwa. Pasinei nezvimwe zvinonetsa, kufambira mberi uye kufambira mberi kuMellanse muCellulose Chemistry kunogona kuwedzera kuwedzeredza mashandisirwo uye kugadzirisa basa reHPMC mune ramangwana.
