HydroxyPropyl methylcellose (HPMC) iri yakajairika semi-synthetic polymer zvinhu uye cellulose inobva. Icho chisiri-ionic mvura-soluble polymer yakagadzirwa nemakemikari kugadzirisa mamiriro echisikigo. Maitiro ekugadzirira eHPMC anowanzo kusanganisira matanho anotevera: Almalizing Cellalose kurapwa uye methyl chloride mamiriro ekugadzira hydroxyprosyl
Chemical chimiro uye zvivakwa zveHPMC
Iyo yekutanga nzvimbo yeHPMC iri β-D-Pyranose Glucose, iyo zvakare ndiyo yekutanga mamiriro emheremalose. MuHPMC, mamwe maHydroxyl mapoka (-Oo) anotsiviwa nemapoka mapoka (-Och₃) uye hydroxypriropopochch₃), saka chimiro chayo chakasiyana neicho chemasikirwo emusango cellulose. Uku kutsiviwa kunovandudza iyo solubility yeHPMC mumvura uye imwe organic soles, uye ine yakagadzikana yakanaka uye yakaderera hygroscopiciticitifity.
Hpmc yakanyungudutswa mumvura, inogona kuumba mhinduro yakagadzikana cooludal. Yayo solubility ine hukama nerudzi uye degree rekutsiva kweiyo substituent. Kazhinji, HPMC ine yakakwira zvemukati methyl Subhts Mukuwedzera, HPMC Solutions vane zvivakwa zveTermogeli, ndiko kuti, ivo vangere kana vachipiswa nekunyungudika zvakare kana vachidzikama.
Minda yekushandisa yeHPMC
Nekuda kweiyo yakasarudzika yemakemikari yemakemikari uye physicochemical zvivakwa, HPMC yakave yakashandiswa zvakanyanya muminda yakawanda.
Zvivakwa zvekuvaka: Muzvivakwa zvekuvaka, HPMC inowanzo shandiswa seyakavharira uye mvura ichengetera mumiririri kuti uvandudze mashandiro echigadzirwa uye gypsum-based zvigadzirwa uye mhando yechigadzirwa chekupedzisira. Izvo zvinogona zvakare kuvandudza kuderedza, kupenga kuramba uye kusimba kwemutya.
Mushonga: Iko kushandiswa kweHPMC mumunda wemishonga kunyanya kunosanganisira kudzorwa kusunungurwa kuburitsa zvigadzirwa, capsule mashells uye nhaurwa dzemapiritsi. Nekuti HPMC isiri-ine chepfu, isingadzivisike uye ine yakanaka yekukanganiswa, inoshandiswa zvakanyanya mukusunungurwa-kwakasunungurwa uye kudzoreredzwa uye kudzoreredzwa-kubhadharwa kugadzirira mahwendefa.
Chikafu: Mune indasitiri yekudya, HPMC inoshandiswa seanoshandiswa sedhizimusi, stabilizer uye emulsifier mukugadzirwa kwezvekudya zvakasiyana, jegurt, etc.
Cosmetics: Mumunda weCosmetics, HPMC inowanzoshandiswa seanosvitswa seclesions, tsvina uye gels. Izvo hazvingopa chete chimiro chakanaka, asi zvakare chinoumba firimu rinonyorova pane ganda pamusoro peganda, nekudaro vachiridza basa rekunyorova uye rinodzivirira.
Mbira: HPMC inoshandiswa seanoshandiswa sediki, inopararira uye inofungidzira mumarara, iyo inogona kuvandudza kuita kwekuvaka kwejasi uye kuvandudza huwandu uye gloss yejasi.
Zvakanakira uye zvisingakwanisi zveHPMC
HPMC ine zvakawanda zvakanakira, senge yakanaka mvura solubility, makemikari kugadzikana, kusiri-hutachiona uye biocomputer. Aya maitiro akaita kuti izoshandiswe zvakanyanya muminda yakawanda. Nekudaro, HPMC zvakare ine zvimwe zvausingakwanisi. Semuenzaniso, pasi pemamiriro ekunze akanyanya, iyo viscosity yeHPMC inodonha zvakanyanya, iyo inogona kuve dambudziko mune mamwe maapplication. Mukuwedzera, HPMC ine kusimba isina kusimba mumhinduro dzakakura dzekusimbisa munyu, izvo zvakare zvinodzikamisa zvakare mashandisiro ayo munzvimbo dzinokosha.
HPMC ndeye yakakosha inoshanda inoshanda polymer. Nezvivakwa zvayo zvakasarudzika uye zvemakemikari uye zvakanaka mashandisiro ekushandisa, zvakange zvichishandiswa zvakanyanya mukuvaka, mushonga, chikafu, cosmetics uye huku. Kunyangwe iyo ine mamwe miganhu, iyo nzvimbo yekushandisa yeHPMC ichiri kuwedzera kuburikidza nekuenderera mberi kwekutsvaga nekuvandudza. Nekuvandudzwa kwesainzi uye tekinoroji, HPMC inotarisirwa kutamba yakakosha basa rakakosha mune mamwe minda.
