Hydroxyprupyl methylcellose (HPMC)Is Synthetic yemvura-soluble polymer yakagadzirwa kubva kune yakasikwa cellulose kuburikidza nemakemikari kugadziridzwa. Iyo inoshandiswa zvakanyanya mune yemishonga, cosmetic, chikafu, kuvaka uye mamwe maindasitiri. Iyo ine zvinhu zvakanakisa uye zvemakemikari, izvo zvinogona kuongororwa kubva pane izvo zveSalubility, kugadzikana, viscosity hunhu, etermal kugadzikana, etc.
1. Solubility
Iyo solubility yekimacell®hpmc ndeimwe yezvakanyanya kukosha mumuviri uye makemikari zvivakwa. Inogona kuve yakanyungudutswa mumvura kuti iite mhinduro inoonekera coolidal. Iyo solubility inoenderana zvakanyanya neyakaomarara uremu uye huwandu hwekutsiva hydroxyprupyl uye methyl. Kazhinji, HPMC ine yakaderera molecular uremu inovhara zviri nyore, nepo Hpmc ine yakakwira molecular uremu hunopera zvishoma zvishoma. Mumhedzisiro mhinduro, HPMC haigadzike mhinduro yakasimba yekugadzirisa uye kuratidzira yakajairika polymer solution maitiro. Mukuwedzera, HPMC zvakare ine yakanaka solubility mune imwe organic sol sol sol sol sol sol soles
2. Viscosity Properties
Kuputsika kweHPMC mumvura kunogona kuburitsa mhinduro dzebhokisi dzezvemari dzakasiyana siyana, uye viscosity yayo inonyanya kukanganiswa nezvinhu zvakaita sehuremu, sangano rekutsiva uye tembiricha yeHPMC. Sezvo kusangana kweHPMC inowedzera, viscosity yemhinduro inowedzera zvakanyanya, uye vhiza yemhinduro dzakaumbwa neHPMC yehuremu hwakasiyana-siyana dzakasiyana zvakanyanya. Iyo viscosity zvivakwa zveHPMC inoita kuti iwanikwe zvakanyanya mumisheni uye ezvekudya maindasitiri, kunyanya mukusunungurwa zvinodhaka
Mumhedzisiro mhinduro, iyo viscosity yeHPMC inowanzo kuderera nekuwedzera tembiricha, iyo inoratidza kuti HPMC iri kupisa-inonzwa. Kana tembiricha yakanyanya kukwirira, iyo visikopa yeHPMC Solution inogona kuderera, iyo inoda kutarisisa kwakakosha mune zvimwe zvinoshandiswa.
3. Kugadzikana kwekutonga
HPMC ine yakanaka yekugadzira yakazara mukati meimwe tembiricha yekupisa. Yayo yekukugadzikana kwayo inoenderana zvakanyanya kune iyo molecular uremu, degree rekutsiva uye mamiriro ezvinhu epakatiripiti. Pane tembiricha yakajairwa, iyo molecular chimiro cheHPMC inogadzikana uye isiri nyore kupedza. Nekudaro, kana tembiricha yakanyanya kukwirira, HPMC inogona kunge iri chikamu che hydrolysis kana kushatiswa, iyo inokanganisa mashandiro aro.
Hpmc's Thermk kugadzikana kunoita kuti irambe yakanaka kuita mune mamwe nzvimbo dzakakwirira-tembiricha (dzakadai mukugadzira chikafu kana zvekuvaka). Nekudaro, kana tembiricha ichikwira imwe nhanho, chimiro cheHPMC chinogona kunge chakakuvadzwa, zvichikonzera kudzvanywa kwekuita.
4. Kugadzikana uye pH kunzwa
HPMC inoratidza yakanaka makemikari kugadzikana pasi peakasiyana phvie. Izvo zvinowanzogadzikana pasi peAcdic, kusarerekera uye zvishoma alkaline mamiriro ezvinhu, asi pasi pemamiriro ekunze eCimoll®hpmc inogona kuchinja, zvichikonzera shanduko mukushandura uye viscosity. Naizvozvo, mune zvimwe zviitiko zvakanyanyisa, zvakakosha kwazvo kugadzirisa iyo pH kukosha kudzora kugadzikana kweHPMC.
HPMC mhinduro ine imwe phensi yekunzwa. Kunyanya mune mamwe mishonga kana yezvinhu zvigadzirwa, HPMC inowanzoshandiswa kugadzirira mafomu ekudzora-legeti Iyi pfuma yakakosha kwazvo mune yakasarudzika-yekuburitswa system yezvinodhaka uye inogona kudzora kusunungurwa kwezvinodhaka.
5. Mechanics Properties
HPMC, sepamhepo yezvinyorwa, ine imwe musimboti wemakaniki. Mhinduro kwayo yemvura yakaumbwa pane dzakasiyana kutarisisa ine imwe yakasarudzika simba uye elastic modulus. Kunyanya kana uchigadzira firimu, HPMC inogona kuratidza yakanaka michina. Izvi zvinogonesa kupa yakanakisa kudiwa uye kupokana kwemamiriro ekunze apo yakashandiswa seyakagadzirwa firimu kana thickener mune yekuvaka indasitiri.
6. Gelling Pfuma
HPMC ine zvivakwa zvine simba, kunyanya pakadzika, inogona kuumba hurongwa hwakagadzikana nemvura. Maitiro ayo aro ane hukama zvakanyanya neyakaomarara uremu, iyo mhando uye yekuvhara kwevasiki. Pasi pemamiriro ezvinhu akakodzera, HPMC inogona kushandiswa seanotenderera, gelling mumiririri kana emulsifier, iyo inoita kuti iwaniswe zvakanyanya mukudya, mushonga, cosmetics nedzimwe minda.
7. Basa repamusoro
HPMC ine imwe nzvimbo yemasosi nekuti ine hydrophilic uye hydrophobic mapoka. Pasi pemamwe mamiriro, Kimacell®hpmc inogona kuderedza iyo yekunetsana yemvura uye kushandiswa seye surfactant. Mune mishonga uye cosmetics, hpmc inoshandiswa zvakanyanya sechiitiko uye inopararira, iyo inogona kusimudzira kusanganisa kwemvura-mvura uye kugadzirisa kugadzikana kwechigadzirwa.
8. Biocompuility
HPMC ine yakanaka biocomputilation uye saka inoshandiswa zvakanyanya mumunda webionical. Haisi nyore kucherwa uye inonyudzwa mumuviri uye inowanzoshandiswa seinodhaka inotakura zvinodhaka Nekuda kweiyo yakakwirira kwazvo molecular uremu, HPMC kazhinji haikonzeri immune mhinduro kana mamwe mhedzisiro uye yakakodzera kutungamira kwezvinodhaka kuburikidza nemataurire akasiyana-siyana senge momuromo, misoro uye jekiseni.
Hpcine zvinhu zvakanakisa zvemuviri uye zvemakemikari, kusanganisira yakanaka solubility, inoshandurwa viscosity, inogadzirisa kugadzikana, makemikari kugadzikana uye biocomputer. Izvi zvivakwa zvinoita kuti zvishandiswe zvakanyanya mumaindasitiri mazhinji senge mishonga, chikafu, cosmetics uye kuvaka. Kunzwisisa kwakadzama kwezvinhu zvaro zvemuviri uye zvemakemikari zvichabatsira gadzirisa maitiro ayo anoshanda muminda dzakasiyana siyana.
