Hydroxyprupyl methylcellose (HPMC) is a loluble polymer yakawanikwa yakawanikwa nemakemikari kugadziridzwa kwemusango chirimwa cellulose. Iyo ine yakanaka solubility, kugadzikana uye kusashandiswa, uye inoshandiswa zvakanyanya muchikafu, mushonga, kuvaka, zvizhinyama uye zvimwe minda. Izvi zvinotevera zvichasuma maitiro ezvekugadzira, nzira dzekugadzirira, maincation main uye zvakanakira hpmc zvakadzama.
1. Chemical chimiro uye zvivakwa
Iyo yekutanga chimiro cheHPMC inotorwa kubva kune yakasikwa cellulose. Pamhepo yayo yemulecular, mamwe mahydroxyl mapoka (-oh) anotsiviwa ne methyl mapoka (-ch3) uye hydroxpropyl mapoka (-ch2chohch3). Yayo chaiyo yemakemikari chimiro inogadzirwa nekuchinja kweCellulose mamorekuru, iyo inopa iyo yakanaka mvura solubility, yakakora uye yefirimu-inoumba midziyo.
Iyo mvura solubility yeHPMC yakanyatsoenderana neiyo degree rekutsiva methyl uye hydroxypruspropyl mapoka mumorekuru. Kazhinji, HPMC ine hunhu hunotevera:
Yakanaka mvura solubility;
Kugadzikana kwakanaka, kushivirira kwakasimba kupisa uye asidhi naAlkali;
Yakakwira viscossity, yakasimba inosimbisa mhedzisiro;
Nekuda kwechimiro chayo chemakemikari, HPMC inogona zvakare kuumba firimu uye ine imwe yekudzoreredzwa kusunungurwa pamishonga kana zvimwe zvinhu.
2. Kugadzirira nzira
Kugadzirira kweHPMC kunonyanya kuwanikwa kuburikidza neyetsika yekuita cellulose. Cellulose Kutanga Inosarudza neMethyl Chloride (Ch3cl) uye HydroxyPropyl Chloride (C3H7Och2CL) Kuti uwane methylated uye hydroxyprunlated zvigadzirwa. Zvichienderana nemamiriro ezvinhu ekuita (senge tembiricha, maitiro ekushisa, ratio yezvinhu zvisina kugadzirwa, etc.), kurema kwemanyorerwe uye mamwe emuviri uye makemikari zvivakwa zveHPMC inogona kugadziriswa. Matanho chaiwo ari seanotevera:
Cellulose inonyungudika kubvisa kusvibiswa.
Ita ne methyl chloride uye hydroxyprupyl chloride mune alkaline solution yekuchinja kwetsika.
Iyo yekupedzisira HPMC chigadzirwa inowanikwa kuburikidza nekupararira, filtration, kuoma uye mamwe matanho.
3. Munda Unonyorera
3.1Pharmaceutical munda
Muindasitiri yechechi, HPMC inoshandiswa zvakanyanya seyakanakisa madhiragi. Izvo hazvishandiswe chete seanongoswe, asi zvakare inogona kushandiswa kugadzirira gadziriro dzinodzora-zvinodhaka. Yakanakisa mvura solubility uye biocompukile inoita kuti ive yakakosha mukugadzirira kweMishonga senge mapiritsi, makapitsi, nemapiritsi. Zvikumbiro zvakajairika zvinosanganisira:
Kusunungurwa kwezvinodhaka kusunungurwa: Hpmc inogona kupera zvishoma nezvishoma mumuviri uye kusunungura zvinodhaka, saka zvinowanzoshandiswa kugadzirira kusunungura-kusunungura zvinodhaka.
Kutakura kwezvinodhaka: HPMC inogona kushandiswa seinotakura yekuumbwa uye kupararira kana kugadzirira capsules, mapiritsi, mahwendefa uye mamwe mafirita.
Gel: HPMC inogona kushandiswa segwenzi yekugadzirira gel dosage mafomu emishonga dzakasiyana-siyana mishonga, yakadai seyemafuta ehukama.
3.2 Chikafu Chikafu
Hpmc iri zvakare inoshandiswa zvakanyanya muindasitiri yechikafu, kunyanya kuvandudza chimiro chechikafu, wedzera hupenyu hwesherufu, uye uvandudze kuravira kwechikafu. Zvikumbiro zvakajairika zvinosanganisira:
Thickener uye Stabilizer: HPMC inogona kushandiswa seyakavharira mune zvekudya zvakadai seJelly, saladi kupfeka, uye ice cream kuti uwedzere vhiza uye kugadzikana kwechikafu.
Geaving Agent: Mune zvimwe zvekudya, HPMC inogona kushandiswa segomba mumiririri kupa yakanaka gel.
Chingwa uye Pastries: HPMC inogona kuvandudza kuravira kwechingwa uye maPastries, wedzera kuomarara kwavo uye kuderedza kuomesa kwechikafu.
3.3 Indasitiri yekuvaka
HPMC inonyanya kushandiswa seyakanyanya uye yekuchengetedza mvura yekuvakisa zvekuvaka senge simende, gypsum, uye pendi muindasitiri yekuvaka, uye inowanzoshandiswa mune zvinotevera zvinhu:
Moturu: HPMC inogona kuwedzera kudenha, kuchengetwa kwemvura uye fluidity yemutya, uye kugadzirisa basa rekuvaka remutya.
Tile Adhesive: HPMC inogona kuvandudza kuita kwekuvaka kwe tiles inonamatira uye nekuwedzera pekupindirana kwayo.
Paint: Uchishandisa HPMC muPendi inogona kuwedzera vhiza uye kugadzikana kwependi, uye batsira kudzora kuunganidzwa kwependi.
3.4 Indasitiri yeCosmetic
Mune cosmetics, HPMC inonyanya kushandiswa seyakakwenenzverwa, yemumhanzi uye inoshandiswa mumiririri, uye inoshandiswa zvakanyanya muzvigadzirwa zvakadai, kuchenesa, chiso chekuchenesa, tsvuku sprays, uye mimvuri yemaziso. Mabasa ayo anosanganisira:
Thickener: HPMC inogona kuwedzera vhiza yezvizoro uye simbisa kunzwa kwekushandiswa.
Moisturizer: HPMC ine yakanaka moisturigizing zvivakwa uye inogona kubatsira kukiya mumunyoro kuti iite kuti ganda rinyorwe.
Emulsifier: Hpmc inogona kubatsira mvura uye kusanganisa kweoiri kuti iite mbolsion yakagadzikana.
4. Zvakanakira uye zvisina kunaka kuongorora
4.1 Kubatsira
Yakanaka Biocompuility: HPMC ndeyechisikigo cellulose chigadzirwa, kazhinji chisiri chepfu uye chisina kujairika kumuviri wemunhu, uye zvine biookigoni yakanaka.
Asina kuravira uye kusavimbika: HPMC kazhinji haina kunhuhwirira kana kutsamwisa uye yakakodzera chikafu nemushonga.
Kushandiswa kwakawanda: nekuda kwekunakirwa kwemvura kwayo kwemvura, kureruka uye kugadzikana, HPMC inoshandiswa zvakanyanya mumaindasitiri akawanda.
4.2 Zvakashata
Kugadzikana kwehurombo pakudziya kwakanyanya: Kunyangwe Hpmc ine yakanaka yekudzikisira, yekudziya kwenguva refu pasi pemamiriro ekunze ekushisa kuchaita kuti hydrolyze uye kushatisa, kurasikirwa nemamwe mabasa ayo.
Mutengo wakakwira: Kuenzaniswa nedzimwe tsika dzechinyakare, HPMC inodhura, iyo inogona kudzikisira kushandiswa kwayo kwakapararira mune zvimwe zvekushandisa.
Semanyorero akanaka kwazvo.Hpc yakave ichishandiswa zvakanyanya mumushonga, chikafu, kuvaka, cosmetics uye mamwe minda nekuda kwekunetseka kwayo kwemvura yakanaka, biocompuility uye kugadzikana. Nekuvandudzwa kwesainzi uye tekinoroji uye kuenderera mberi kwekuvandudza kwezvido zvekushandisa, iyo yekugadzirira tekinoroji uye nzvimbo dzeHPMC ichave yakawedzera kuwedzeredzwa.
