Zvese zviri zviviri hydroxypropyl methylcellose uye hydroxythell cellulose is cellulose
Hydroxyprupyl methylcellose (HPMC)uye hydroxytHyl Cellulose (Hec) pane maviri akakosha cellulose anotora zvakanyanya anoshandiswa mumasango akasiyana siyana nekuda kwezvivakwa zvavo zvakasarudzika. Nepo vese vari vaviri vanotorwa kubva ku cellulose, vane mitsara yakasiyana yemakemikari uye kuratidzira maitiro akasiyana uye maapplication.
1. Nhanganyaya kune Cellulose Decivatives:
Cellulose ndeyepolseccharide inowanikwa mumadziro emasero emasero, inosanganisira mitsara yemitsetse yeGlucose Units ne β (1 → 4) Glycosics Zvisungo. Cellulose Derivatives inowanikwa nemakemikari kugadzirisa cellulose kuti uwedzere zvinhu zvakananga kana kuunza matsva mashandiro. HPMC uye HPM CLE ZVIMWE ZVIMWE ZVAKAWANDA ZVINOGONESESESESESESESESESESESESESESESESESESESESESESESESESESI MUNYAYA DZINOGARA Kubva kuMisheseUneuticals Kuvaka Kuvaka.
2. Synthesis:
HPMC inoenderana nekuita cellulose nePropylene oxide kuti uise hydroxyprospropropropropropropropropropropropropropropropropropropropropropropropyl mapoka uye yakazotevera methyl chloride mapoka methyl. Izvi zvinoguma nekutsiva kwehydroxyl mapoka muCellulose Chain, kupa chigadzirwa neakavandudzwa solubility uye mafirimu ekugadzira mafirimu.
HEC, kune rumwe rutivi, inogadzirwa nekuita cellulose neEtralone oxide kuti iise hydroxyt mapoka ehydroxethyl. Dhigirii rekutsiva
3. Chemical chimiro:
HPMC uye Hec akasiyana mumhando dzemapoka ekutsiva dzakabatanidzwa kune cellulose backbone. HPMC ine zvese hydroxyropropyl uye methyl mapoka, neechera ine hydroxyteth mapoka. Aya akaomesa aya anopa hunhu hwakasarudzika kune mumwe nemumwe anobva, achipesvedzera maitiro avo mune dzakasiyana siyana application.
4. Zvivakwa zvemuviri:
Zvese HPMC uye HPMC temvura-manyorerembudzi mapuranga ane manyoro akakora akanaka. Nekudaro, ivo vanoratidza misiyano mu viscosity, hydration kugona, uye kugona kwemafirimu. HPMC kazhinji ine yakakwira viscosity zvichienzaniswa nehyoko pane yakaenzana kutarisisa, ichiita kuti zviite kuti zvibodzwa zvinoda kurerutsa kukuru.
Pamusoro pezvo, HPMC mafomu akajeka uye akawandisa mafirimu nekuda kweiyo methyl methyl siki, nepo hec maficha anodzikama uye mafirimu anochinja-chinja. Aya misiyano muzvivakwa zvefirimu anoita kuti mumwe nemumwe awane akakodzera kuti anyatso nyorera mumishonga yemishonga, zvigadzirwa zvega, uye maindasitiri ezvekudya.
5. Zvishandiso:
5.1 Indasitiri yeCharmaceuce:
Vese HPMC uye HPMC uye HPMC Vanovandudza kutendeka piritsi, kudzora kusunungurwa kwezvinodhaka, uye kusimudzira muromo mune zvemvura mafomu. HPMC inodaidzwa kuti isimbe-yakaburitswa-yekuburitswa inoenderana neyakainonoka hydration chiyero, nepo hec inowanzo shandiswa mumhinduro dzeOPHTRIMIC uye kujekesa kwayo uye kuwirirana neyebenzi.
5.2 Indasitiri yekuvaka:
Muindasitiri yekuvaka,HpcuyeHecvanoshandirwa sevanowedzera mumidziyo-yakavakirwa zvinhu, vakadai sevhudzi, grass, uye vanopa. Vanovandudza kudzorera, kudzoreredza kwemvura, uye kuderedza, zvichikonzera kushanda kwakavandudzwa uye kusimba kwechigadzirwa chekupedzisira. HPMC inowanzo sarudza iyo yakakwira mvura yekuchengetedza simba, iyo inoderedza kupaza uye inovandudza kugara nguva.
5.3 Zvigadzirwa zvega zvega:
Ose ari maviri anotsvaga zvikumbiro muzvinyorwa zvega zvega senge shampoos, marara, nemakirimu sekuremerwa, emulsifiers, uye stabilizer. Hec inopa chimiro chakanyatsojeka uye chakajeka chekugadzira, zvichiita kuti zviite zvakaringana nezvinhu zvekuchengeta bvudzi uye mafuta eganda. HPMC, ine zvivakwa zvakakura-firimu zvekugadzira, zvinoshandiswa mune zvezuva nezuva uye cosmetic mafomu anoda kudzikisira kwemvura uye kupfeka kwenguva refu.
5.4 Chikafu Chekudya:
Muindasitiri yechikafu, HPMC neHPMC uye Hec inoshanda seVamiririri vakanyanya, maStabilizers, uye machira muzvigadzirwa zvakasiyana siyana kusanganisira masaga, akapfeka, uye zveshuwa. Ivo vanogadzirisa muromo, kudzivirira synesa, uye kusimudzira hunhu hwekunyepedzera hwekugadzira chikafu. HPMC inowanzoda kujeka kwayo uye kupisa kugadzikana, ichiita kuti iite kuti zvikumbiro zvinoda kuti zvibudise zasi uye emambo dzakagadzikana.
6. Mhedziso:
HydroxyPropyl methylcellose (HPMC) uye hydroxytHELL Cellulose (HEC) ndeye cellulose inobva nemakambani akasiyana emakemikari, zvivakwa, uye zvinoshandiswa. Nepo vaviri vacho vanopa zvakanakisa zvinokonzeresa uye mafirimu ekuumba midziyo, ivo vanoratidza misiyano mu viscosity, kujekesa kwefirimu, uye maitiro ehuma. Kunzwisisa misiyano iyi kwakakosha kuti usarudze zvakakodzera zvinobva kune mamwe maashandirwi akadai se mishonga, kuvaka, kutarisirwa kwako, uye chikafu. Sezvo kutsvagurudzo kuri kuramba kuchienderera mberi, kuwedzera shanduko uye zvekushandisa kwemasauro zvinofungidzirwa, zvichikonzera kukosha kwavo kwekuenderera mberi mumatunhu ehondo dzakasiyana siyana.
