Hydroxyprupyl methylcellose (HPMC)Icho chinonyadziswa-mvura-yemvura chakashandiswa-siyana chinoshandiswa zvakanyanya muminda yekuvaka, mushonga, chikafu neindasitiri yemakemikari. Kuchengeta kwayo kwemvura kwayo kunoita kuti iite kuti iite basa rakakosha muzvishandiso zvakawanda maindasitiri.
HPMC ndeye isiri-ionic cellulose ether yakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusangano akadai sea alkalization uye otera. Nekuda kwekukakavara kwayo kwakanaka, kwefirimu, kwemvura uye midziyo yemvura, iyo inoshandiswa zvakanyanya mumarara, marara, mahombekombe, mahwendefa emishonga uye mamwe mishata. Muzvivakwa zvekuvaka, iyo mvura yekuchengetwa kweKimacell®hpmc zvakananga zvinokanganisa maitiro ekuvaka uye akakosha kuita, saka kukosha kukuru kwekudzidza kwemvura yekuchengeta kwayo kwemvura.
1. Molecular chimiro uye mvura yekuchengetera michina yeHPMC
Iyo yekutanga skeleton yeHPMC ndeye cellulose, uye iyo hydroxyl chikamu chakatsiviwa nehydroxypruppropyl uye methyl, iyo inoita kuti ive neyakagwinya mvura uye nekuchengetwa kwemvura. Iyo yekuchengetwa kwemvura yeHPMC inonyanya kusanganisira zvinotevera zvinhu:
Hydrogen Kusungwa: HPMC mamorekuru ane huwandu hwe hydroxyl mapoka, ayo anogona kuumba hydrogen zvishamiso nemamolekyudhi emvura, adsorb uye chengetedza mvura, nekukasira kudzvanyirira mvura yekuchengetwa kwemvura yezvinyorwa.
Kugadziriswa kwakasiyana-siyana.
GEL EYA: HPMC Solution ichaita kuti iumbi leges pane imwe tembiricha yekugadzira network chimiro, izvo zvinobatsira kuchengetedza mvura.
2. Zvinhu zvinokanganisa iyo yekuchengetwa kwemvura yeHPMC
Kuchengetwa kwemvura kweHPMC kunokanganiswa nezvinhu zvakawanda, kusanganisira zvinongedzo zvinorema, degree rekutsiva, mhinduro yekusimbisa uye zvinhu zvekunze zvezvakatipoteredza.
Solecular uremu: HPMC ine yakakura molecular uremu ine simba rakakomberedza, nekukonzeresa kudzokorora kwemvura, asi chiyero chekunyungudika chinononoka.
Dare rekutsiva: Iyo nzira uye hydroxypruppropyl yekutsiva madhigiri eHPMC inokanganisa iyo yekudzora kwayo kwemvura uye nekuchengetwa kwemvura. Danho rakakodzera rekutsiva rinobatsira kuvandudza maitiro ayo ekuchengetedza mvura.
Kugadzirisa Solution: Iyo yepamusoro yeHPMC yekuvhara, iyo yakakura yekubvunzana, uye iyo huru inotadzisa kusiyana kwemvura, nokudaro ichivandudza iyo yekuchengetedza mvura.
Zvinhu zvakatipoteredza: Mamiriro ekunze akadai sekupisa uye humbozha ane kukosha kwakakosha pane yekuchengetedza mvura yeHPMC. Nzvimbo dzakakwirira dzekupisa dzinogona kukurumidza kubuda kwemvura, asi iyo inopisa magetsi eHPMC inogona kuderedza izvi kusvika kune imwe nhanho.
3. Kuchengetwa kwemvura kweHPMC mune akasiyana mashandiro ekushandisa
Zvivakwa zvekuvaka: Muzvinyorwa zveMutambi uye Gypsum-based®hpmc zvinogona kudzivirira kurasikirwa kwemvura nekukurumidza, kugadzirisa mashandiro ekuvaka, kuderedza marara, uye kuwedzera simba.
Kugadzirira kweMishonga: Mumapiritsi eMishonga, HPMC inogona kushandiswa seyakavhurika-yekuburitswa zvinhu kudzora chiyero chekusunungurwa kwemvura uye kuvandudza kugadzikana kwezvinodhaka.
Indasitiri yezvokudya: HPMC inoshandiswa seyakagwinya uye moisturizer yekuvandudza kuravira nekuchengetedzwa kwechikafu.
Ine chimiro chayo chemakemikari,HpcIne huwandu hwakawanda hwekushandisa kwekushandisa mumunda wekuvaka, mushonga, chikafu, etc.
