Hydroxypropyl methylcellulose (HPMC)isiri-ionic cellulose ether. Nekuda kweiyo yakasarudzika yemuviri uye makemikari zvimiro uye kuwanda kwekushandisa kwekushanda, yave chinhu chakakosha mumaindasitiri mazhinji.
1. Hunhu hwehydroxypropyl methylcellulose
Chimiro cheHPMC chinowanikwa nemakemikari ekugadzirisa cellulose. Iine mvura yakanaka yekunyungudika uye kugadzikana, uye ine zvakasiyana-siyana zvemhando yepamusoro:
Yakanakisa solubility yemvura: AnxinCel®HPMC ine yakanaka solubility mumvura inotonhora uye inogona kugadzira inoonekera colloidal mhinduro. Solubility yayo haizochinji zvakanyanya nekuda kwekuchinja kwepH kukosha, uye yakakodzera kushandiswa munzvimbo dzakasiyana.
Kukora uye kugona kubatanidza: HPMC ine yakakosha kukora mhedzisiro uye yakasimba yekubatanidza simba, iyo inogona zvinobudirira kuvandudza viscosity uye rheological zvimiro zvezvinhu. Ichi chimiro chinonyanya kukosha mukuvaka zvinhu, machira uye zvizoro.
Kugadzira firimu uye kuchengetwa kwemvura: HPMC inogona kuumba yunifomu firimu uye inopa yakanakisa zvipingamupinyi kudzivirira. Panguva imwecheteyo, pfuma yayo yekuchengetedza mvura inobatsira kuwedzera nguva yekushandiswa kwechigadzirwa uye kuvandudza kushandiswa kwekushandisa.
Kugadzikana kwakasimba: HPMC inodzivirira chiedza, inodzivirira kupisa, uye inopesana neoxidation, uye inochengetedza kugadzikana kwekemikari muhupamhi hwepH, iyo inoita kuti ishande zvakasimba pasi pemamiriro akawanda ekushanda anokosha.
Isiri-chepfu uye ine hushamwari kwezvakatipoteredza: HPMC haina chepfu kumuviri wemunhu uye inogona kugadzirwa biodegraded, iyo inosangana nezvinodiwa nenharaunda yemazuva ano yekuchengetedzwa kwezvakatipoteredza nekuchengetedza.
2. Nzvimbo dzakasiyana-siyana dzekushandisa
HPMC inoshandiswa zvakanyanya mumaindasitiri mazhinji nekuda kwekusiyana-siyana kwayo, kunyanya kusanganisira dzinotevera nzvimbo:
Munda wekuvaka: HPMC inokosha yekuwedzera mune zvekuvaka, inoshandiswa kune yakaoma dhaka, tile inonamira, isina mvura yekuputira, nezvimwe. Inogona kuvandudza mashandiro ekuvaka emidziyo, sekusimudzira kushanda, kuvandudza anti-sagging performance, nekuvandudza bonding simba uye kusimba.
Mishonga uye maindasitiri ezvekudya: Mumunda wemishonga, HPMC inoshandiswa sebhainda, inosimudzira-yakaburitswa zvinhu uye capsule zvinhu zvemapiritsi; muindasitiri yezvekudya, inoshandiswa seyakakora, stabilizer uye emulsifier kubatsira kuvandudza magadzirirwo nekuchengetedza chikafu.
Indasitiri yemakemikari yemazuva ese: HPMC inowanzo shandiswa muzvizora uye zvigadzirwa zvekuchengeta munhu, senge lotions, kuchenesa kumeso uye maconditioners, kukora, kugadzira mafirimu uye kunyorova, uye kuwedzera magadzirirwo uye kushandisa ruzivo rwezvigadzirwa.
Coatings uye pendi: HPMC inoshandiswa mumvura-based coatings kuti ivandudze kuenzana kwayo uye sagging zvimiro, uku ichiwedzera kunamatira uye kusimba kwejasi.
Zvekurima nemimwe minda: Mukurima, HPMC inoshandiswa semushonga wekuputira mbeu uye inochengetedza mvura; inoshandiswawo muindasitiri yeceramic uye indasitiri yemagetsi, kunyanya kuvandudza rheology uye kugadzikana mukugadzira tekinoroji.
3. Kudiwa kwemusika kunosundwa
Iko kushandiswa kwakakura kweHPMC hakungori nekuda kwekuita kwayo kwakanaka, asiwo nekuda kwekusimudzirwa kwezvido zvemaindasitiri zvemazuva ano:
Kukurumidza kusimukira kweindasitiri yekuvaka: Iyo yakakwirisa yepasi rose kuvaka kwezvivakwa uye kuita kwemaguta kwakafambisa kudiwa kwezvinhu zvepamusoro-soro zvekuvaka, uye kuita kwakasiyana-siyana kweHPMC muzvivakwa zvekuvaka kunoita kuti ive yekuwedzera isingadzokerike.
Hutano uye kuziva kwezvakatipoteredza zviri kuwedzera: Vatengi vane kuwedzera zvinodiwa zvekuchengetedza uye kuchengetedzwa kwezvakatipoteredza kwemishonga, chikafu uye zvemazuva ese zvigadzirwa zvemakemikari. HPMC inofarirwa neindasitiri nekuda kweiyo isiri-chepfu, isingakuvadzi uye inoshatisa zvivakwa.
Kufambira mberi kwetekinoroji uye kuvandudzwa kwechigadzirwa: AnxinCel®HPMC's tekinoroji yekushandisa inoenderera mberi nekuvandudza, kuwedzera mashandisirwo ayo mundima dziri kusimukira dzakadai seye 3D yekudhinda zvekuvaka, machira akangwara uye chikafu chinoshanda.
Iko kudikanwa kwekutsiva zvechinyakare zvinhu: Mune akawanda maapplication, HPMC zvishoma nezvishoma yakatsiva zvechinyakare zvinhu uye ikava sarudzo ine hupfumi uye inoshanda.
Hydroxypropyl methylcellulosechave chinhu chakakosha chakakosha mumaindasitiri mazhinji nekuda kwekuita kwayo kwakanakisa, kushandiswa kwakasiyana-siyana uye kukwira kwepamusoro nekudiwa kwemusika. Nekumwe kukwidziridzwa kwekufambira mberi kwetekinoroji uye kuziva kwezvakatipoteredza, munda wekushandisa weHPMC ucharamba uchikura, uye tarisiro yayo yemusika yakakura kwazvo.
