Hydroxyprupyl methylcellose (HPMC) uyeHydroxytHyl Cellulose (Hec) Vese vari vaviri cellulose vanobva, vanoshandiswa zvakanyanya muindasitiri, mushonga, zvizhinyamo uye mamwe minda. Misiyano yavo huru inoratidzwa mumanyorerwe emanyorerwo, solubility maitiro, minda yekushandisa uye zvimwe zvinhu.
1. Molecular chimiro
Hydroxyprupyl methylcellose (HPMC)
HPMC ndeyemvura-inokwenenzverwa kubva kuSEIVACE YAKAITWA NEMAHARA (-CH3) uye hydroxyprupyl (-ch2chohch3) mapoka mune cellulose molecular cheni. Kunyanya, iyo molecular chimiro cheHPMC ine maviri anoshanda anoongorora, methyl (-Och3) uye hydroxypruppropyl (-Och2ch (oh) ch3). Kazhinji, sumo yacho yeMethyl yakakwira, nepo hydroxypruppropyl inogona kubatsira zvinobudirira iyo solubilse yemheremalose.
HydroxytHyl Cellulose (Hec)
HEC idzore yakaunzwa nekuunza ethyl (-ch2ch2oh) mapoka muCellulose Molecular Chain. Muchimiro chehydroxyethyl cellelose, imwe kana kupfuura hydroxyl mapoka (-OOH) yemasero inotsiviwa neEtiyl hydroxyl mapoka (-ch2ch2oh). Kusiyana neHPMC, iyo molecular chimiro chehec ine chete hydroxytethyl kutsiva uye haina methyl mapoka.
2. SoluBility yemvura
Nekuda kwekusiyana kwekusiyana, iyo mvura solubility yeHPMC uye Hec yakasiyana.
HPMC: HPMC ine yakanaka mvura solubility, kunyanya pakurerekera kana zvishoma alkaline ph kukosha, iyo solubility iri nani pane hec. Sumo yeMethyl uye hydroxypruspropyl mapoka anowedzera iyo solubility uye inogona zvakare kuwedzera viscosity kubudikidza nekudyidzana nemamolekyudhi emvura.
HEC: Hec inowanzo kuvezwa mumvura, asi iyo solubility iri murombo, kunyanya mumvura inotonhora, uye kazhinji inoda kunyungudika pasi pekupisa mamiriro kana kuti inoda kutarisisa kwakakwirira kuti uwane miganho yakafanana. Yayo solubility ine chekuita nemisiyano yakasarudzika yemheremellose uye hydrophilikuti yeiyo hydroxyteth boka.
3. Viscosity uye rheological zvivakwa
HPMC: Nekuda kwekuvapo kwemapoka maviri akasiyana eHydrophic (metdroxyprospropyl) mumamolekhollows Pazvivakwa zvakasiyana, HPMC inogona kupa kugadziriswa kubva kuKutswa kwesangano kune yepamusoro viscosity, uye viscosity ine hanya zvakanyanya neP.
HEC: Iyo visikopa yehikiyo inogona zvakare kuchinjwa nekuchinja kusimbisa, asi iyo viscosity yekugadziriswa kwehuwandu ndeyekuderera pane iyo yeHPMC. HEC inonyanya kushandiswa mumamiriro ezvinhu apo yakadzika kusvika pakati pekuvonekwa kunodiwa, kunyanya mukuvaka, kugadzirisa uye zvigadzirwa zvega uye zvigadzirwa zvemunhu. Iyo rheological zvivakwa zvehec zvakanyatsogadzikana, kunyanya mune acidic kana isina kwaakarerekera nharaunda, hec inogona kupa zvakanyanya kutarisisa viscosity.
4. Masvondo ekushandisa
Hydroxyprupyl methylcellose (HPMC)
Indasitiri yekuvaka: HPMC inowanzoshandiswa mumutero wetsimusi uye zvipfuyo mune yekuvaka indasitiri yekuvandudza fluidity, kuisirwa uye kudzivirira marara.
Indasitiri yechechi yechechi: Sezvinoita mushonga wekudzora mumiriri, HPMC inoshandiswa zvakanyanya muindasitiri yemishonga yemishonga. Izvo hazvigone kushandiswa chete seyekugadzira mumirapiro matafura nemakapu, asiwo sekunamatira kubatsira zvinodhaka zvakashata.
Indasitiri yekudya: HPMC inowanzoshandiswa mukugadziriswa kwekudya sechiStabilizer, thickener kana emulsifier yekuvandudza iwo maitiro uye kuravira kwechikafu.
Cosmetic Indasitiri: Seganho, HPMC inoshandiswa zvakanyanya muzvigadzirwa zvakadai semakiromita, shampoos, uye inogadzirisa kuti uwedzere kuvenga uye kugadzikana kwezvigadzirwa.
HydroxytHyl Cellulose (Hec)
Indasitiri yekuvaka: Hec inowanzoshandiswa musicement, gypsum, uye inonamira inonamira yekuvandudza iyo fluidity uye kuchengetwa kwenguva yechigadzirwa.
Vanoshambidza: hec inowanzoshandiswa mune vanochenesa veimba, yekuwachira magetsi uye zvimwe zvigadzirwa kuti uwedzere viscosity yechigadzirwa uye kugadzirisa iyo yekuchenesa maitiro.
Indasitiri yeCosmetic: Hec inowanzoshandiswa zvakanyanya mune zvigadzirwa zveganda zveganda, shower Gels, shampoos, etc. Somunyararo uye kumisikidza mumiriri kuti uvandudze chimiro uye kugadzikana kwechigadzirwa.
ORFLCATE: HEC inogona zvakare kushandiswa mune iyo mafuta ekurwiswa seyekupedzisira mumvura-yakavakirwa mvura yekukwevera mvura kuti uwedzere kuwanda kwemvura uye kugadzirisa iyo yekudhara.
5. PH Kugadzikana
HPMC: HPMC ine yakanyanya kutaridzika kune pH shanduko. Pasi pemamiriro ezvemukati, iyo solubility yeHPMC inoderera, iyo inogona kukanganisa maitiro ayo. Naizvozvo, zvinowanzoshandiswa mune zvematongerwo enyika kune zvishoma alkaline nharaunda.
Hec: hec inoramba yakagadzikana pamusoro pakawanda ph range. Iyo ine kusimba kwakasimba kune acidic uye alkaline nharaunda, saka inowanzoshandiswa mukuumbwa kunoda kusimba kwakasimba.
HpcuyeHecinosiyana mumanyorerwo, solubility, maVucossity kugadzirisa maitiro, uye nzvimbo dzekushandisa. HPMC ine yakanaka mvura solubility uye viscossity yekugadzirisa maitiro, uye yakakodzera kune zvinoshandiswa izvo zvinoda kukwikwidza kwepamusoro kana yakanyanya kudzorwa kuburitsa kushanda; Ipo heme ine yakanaka ph kusagadzikana uye huwandu hwakawanda hwekushandisa, uye hwakakodzera kuti nguva dzinoda pakati nepakati uye yakaderera viscosity uye yakasimba mamiriro ekunze. Muzvikumbiro chaicho, sarudzo yeiyo zvinhu zvinoda kuongororwa zvichibva pazvinhu zvakananga.
