Hydroxypropyl methylcellulose (HPMC) yakakosha mumvura-inonyungudika nonionic cellulose ether ine yakanaka thickening, gelling, bonding, film-forming, lubricating, emulsifying and suspending mabasa, saka inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu, cosmetics nezvimwe minda. .
Kuomesa nzira yehydroxypropyl methylcellulose
Iko kukora mhedzisiro yeHPMC inonyanya kuuya kubva kune yayo molecular chimiro. Iyo HPMC molecular chain ine hydroxyl uye methyl mapoka, anogona kuumba hydrogen zvisungo nemamorekuru emvura, nekudaro achidzora kufamba pakati pemamorekuru emvura uye kuwedzera viscosity yemhinduro. Kana HPMC yanyungudutswa mumvura, cheni yayo yemamorekuru inovhurika mumvura uye inopindirana nemamorekuru emvura kuti igadzire network network, nekudaro ichiwedzera viscosity yemhinduro. Iko kugona kwekukora kweHPMC kunokanganiswawo nezvinhu zvakaita sedhigirii rekutsiva, huremu hwemamorekuru uye kutarisisa.
Kushandiswa kwehydroxypropyl methylcellulose mune zvekuvaka
Muzvinhu zvekuvaka, HPMC inonyanya kushandiswa muzvigadzirwa zvakaita semendi dhaka, gypsum-based materials uye machira seanokora uye anochengeta mvura. Iko kukora kwaro kunogona kuvandudza mashandiro ekuvaka kwechinhu uye kuwedzera mashandiro ayo e-anti-sagging, nekudaro ichiita kuti maitiro ekuvaka ave akapfava. Semuenzaniso, mudhaka resimende, kuwedzera kweHPMC kunogona kuwedzera viscosity yedhaka uye kudzivirira dhaka kubva pakudonha kana ichivakwa panzvimbo yakatwasuka. Inogonawo kuvandudza kuchengetwa kwemvura kwedhaka uye kudzivirira dhaka kubva pakuoma nekukurumidza, nekudaro kuvandudza simba uye kusimba kwedhaka.
Kushandiswa kweHydroxypropyl Methylcellulose muMunda weMishonga
Mundima yemishonga, HPMC inoshandiswa zvakanyanya mumapiritsi, capsules, gels, ophthalmic kugadzirira uye mimwe mishonga seyakakora, firimu rekare uye rinonamira. Iyo yakanaka thickening mhedzisiro inogona kuvandudza rheological maitiro emishonga uye kugadzirisa kugadzikana uye bioavailability yemishonga. Semuenzaniso, mukugadzirira kwemaziso, HPMC inogona kushandiswa semafuta uye mukobvu, uye kunaka kwayo kukora kunogona kurebesa nguva yekugara yemushonga panzvimbo yemaziso, nekudaro ichivandudza kushanda kwemushonga.
Kushandiswa kweHydroxypropyl Methylcellulose muChikafu
Muindasitiri yezvekudya, HPMC inowanzo shandiswa mukudya senge zvigadzirwa zvemukaka, jellies, zvinwiwa uye zvakabikwa zvinogadzirwa semukobvu, emulsifier uye stabilizer. Iko kukora kwayo kunogona kuvandudza kuravira uye kuumbwa kwechikafu, uye kuwedzera viscosity uye kugadzikana kwechikafu. Semuenzaniso, mune zvigadzirwa zvemukaka, HPMC inogona kuwedzera viscosity yechigadzirwa uye kudzivirira whey kunaya, nekudaro ichivandudza kuravira uye kugadzikana kwechigadzirwa.
Kushandiswa kweHydroxypropyl Methylcellulose muCosmetics
Mumunda wezvizoro, HPMC inoshandiswa zvakanyanya muzvigadzirwa zvakaita semafuta ekuzora, makirimu, shampoos uye maconditioner seanokora, emulsifier uye stabilizer. Kuwedzera kwayo mhedzisiro inogona kuvandudza magadzirirwo uye kugadzikana kwezvizoro, uye kugadzirisa mashandisiro ekushandisa uye ruzivo rwevatengi rwechigadzirwa. Semuenzaniso, mune lotions uye makirimu, kuwedzera kweHPMC kunogona kuwedzera viscosity yechigadzirwa, zvichiita kuti zvive nyore kushandisa uye kunwa, ukuwo uchivandudza hunyoro hwechigadzirwa.
Hydroxypropyl Methylcellulose yakashandiswa zvakanyanya mukuvaka, mishonga, chikafu uye zvizorwa nekuda kwekunaka kwayo kukora zvivakwa. Kukora kwaro kunonyanya kuwedzera viscosity yemhinduro kuburikidza nekugadzira hydrogen zvisungo nemamorekuru emvura, zvichitadzisa kufamba kwemamorekuru emvura. Masimu akasiyana ane akasiyana maapplication eHPMC, asi basa rayo guru nderekuvandudza viscosity uye kugadzikana kwechigadzirwa. Nekufambira mberi kwesainzi uye tekinoroji uye nekuenderera mberi kwekuvandudza tekinoroji yekushandisa, tarisiro yekushandiswa kweHPMC ichave yakakura.
