HydroxyPropyl methylcellose (HPMC) ishandare yakati wandei inowana mashandiro akawanda mumaindasitiri, kusanganisira mishonga yemishonga, chikafu, kuvaka, uye cosmetics, uye cosmetics, uye cosmetics.
1. Nhanganyaya kuHPMC:
HydroxyPropyl methylcellose (HPMC) ndeye semi-synthetic, inert, viscoelastic polymer kubva cellulose. Iyo yakagadzirwa kuburikidza nemakemikari kugadziridzwa kwemheremalose, iyo inosanganisira eriraifiti yeAlkali cellulose neProfylone oxide uye methyl chloride. Chigadzirwa chinokonzeresa chichena kune chena-chena, isina kusimba, uye isina hupfu, isina hupfumi iyo inonyungudika mumvura asi isingaoneki mu organic sol sol.
2. Chimiro uye zvivakwa:
Hpmc's Chimiro chine backbone of cellulose, iyo yepanyama yemhando yakagadzirwa neGlucose Units ne β (1 → 4) Glycosic Zvisungo. MuHPMC, mamwe emapoka ehydroxyl pane zvikamu zveGlucose anotsiva ne 2-hydroxypruppropyl uye methyl mapoka. Uku kutsiviwa kunoshandura zvivakwa zvePolymer zvichienzaniswa nekwavo cellive cellevelose, kuendesa kwakavandudzwa solubility, viscosity, uye kugona kwemafirimu.
Zvivakwa zveHPMC zvisizvo zvichienderana nezvinhu zvakaita seyero yekutsiva Kazhinji, HPMC inoratidza:
Yakanakisa firimu-inoumba zvivakwa
Thermal Glation maitiro
Yakakwira mvura yekuchengetera
Kugadzikana pamusoro peiyo pl red ph range
Kuwirirana nevamwe polymers uye vanowedzera
Zvisiri-ionic zvakasikwa, zvichiita kuti zvienderane nezvinhu zvakasiyana siyana
3. Synthesis yeHPMC:
Iyo synthesis yeHPMC inosanganisira matanho akati wandei:
Alkali Cellulose Kugadzirira: Cellulose inobatwa neAlkaline Solution yekuumba Alkali Cellulose.
Kuwedzera: Alkali Cellalose Inosangana neProfily Oxide uye MetHyl Chloride kuti Uise hydroxyprospropropropropropropropropyl uye methyl mapoka kune iyo cellulose backbone.
Kushambidza uye kucheneswa: Chigadzirwa chinokonzerwa chakashambwa, chisina kururama, uye chakacheneswa kubvisa kusvibiswa.
Kuomesa: Iyo Yakacheneswa HPMC yakaomeswa kuti uwane chigadzirwa chekupedzisira muFowa Fomu.
4. Zvikumbiro zveHPMC:
HPMC inowana inopararira zvikumbiro muindasitiri akasiyana-siyana:
Pharmaceuticals: HPMC inowedzera inoshandiswa seyakaverengeka semishonga muzvinyorwa zvebiritsi, zvinodzorwa-kuburitswa, gadziriso yekugadzirira, uye kumiswa. Iyo inoshanda seye binder, thickener, firimu raimbova, uye rakaburitswa-mumiririri mumufomu akasiyana-siyana.
Indasitiri yeChikafu: Muindasitiri yekudya, HPMC inoshandiswa sedhizimusi, stabilizer, emulsifier, uye kunyorovesa mumiririri mune zvigadzirwa zvakabikwa sezvinhu zvakabikwa, zvigadzirwa zvemukaka, zveshuwa, uye zveshuwa. Iyo inovandudza kuumbwa, rerufu hupenyu, uye muromo mune zvigadzirwa zvekudya.
Kuvaka: HPMC ndeyekiyi inokosha mune zvekuvaka zvakadai seyakagadzirwa-based-based motsa, tile anomisheni, uye zvigadzirwa zveGypsum. Zvinoita seyemvura yekuchengetwa kwemvura, inovandudza basa rekushanda, inoderedza kusimuka, uye inosimudzira kudengenyeka mukuvaka.
Cosmetics: HPMC inoshandiswa mune cosmetics uye neyako ekuchengetedza zvigadzirwa seyakakwenenzverwa, stabilizer, uye mafirimu-ekugadzira mumiririri mune zvigadzirwa, limons, shampoos, uye gels. Iyo inopa visikoka, inovandudza chimiro, uye inopa yakatsiga, isina mafuta inonzwa.
Zvimwe Zvikumbiro: HPMC inoshandawo kudhinda rezvemusoro, ceramics, pendi, inodzivirira, uye seyakagadzirwa mumigwagwa yakasiyana-siyana yemaindasitiri.
5. Zvizororo zvenguva yemberi nematambudziko:
Iko kudiwa kweHPMC kunotarisirwa kuenderera mberi nekukura nekuda kwezvivakwa zvaro zvinhu zvakasiyana siyana uye zvinoshandiswa zvakasiyana. Nekudaro, zvinonetsa sekushandura mitengo yemutengo wezvekushandisa, ekuzvidzora, uye kukwikwidza kubva kune dzimwe polymers kunogona kukanganisa masika masango. Kuedza kwekutsvagisa kwakanangidzirwa pakukwirira kweHPMC.
HydroxyPropyl methylcellose (HPMC) inzvimbo yakakosha polymer ine huwandu hwakawanda hwekushandisa maindasitiri akawanda. Yayo yakasarudzika, zvivakwa, uye Synthesis ita kuti ive chinhu chakakosha mumishonga yemishonga, zvigadzirwa zvekudya, zvigadzirwa zvekuvaka, zvigadziriso, uye zvakasarudzika maindasitiri ekushandisa. Kutsvaga kwekutsvaga uye kusimudzira kuedza kuenderera, HPMC yakagadzirirwa kuramba iri mutambi wendasitiri yePolymer, inopa mhinduro dzisina ruzivo dzekusangana nemusika wekusimuka.
