Hydroxyprupyl methylcellose (HPMC)is is is is-ionic cellulose ether inoshandiswa zvakanyanya muzvivakwa zvekuvaka, mushonga, chikafu, cosmetics nedzimwe minda yeindasitiri. Iyo ine zvakawanda zvakanaka zvemuviri zvivakwa, izvo zvinoita kuti zviite zvakanaka mune dzakasiyana siyana application.
1. Kutaridzika uye solubility
HPMC inowanzove chena kana isina-chena poda, isina kusimba, isina kunaka uye isina-chepfu. Inogona kunyungudutswa mumvura inotonhora uye mamwe organic sol sol sol sol sol sol sol solhanol / mvura uye mvura uye mvura), asi haina kusunganidzwa muakachena ethanol, ether uye chloroform. Nekuda kweiyo isiri-ionic chimiro, hazvizotsi kuita zvemagetsi maitiro mumhedzisiro mhinduro uye hazvizokanganiswe zvakanyanya nePH kukosha.
2. Viscosity uye rheology
HPMC yemvura mhinduro ine yakanaka kuremerwa uye iyo thisiotropy. Mhando dzakasiyana dzekusimba Kugadziriswa kwaro kunoratidzira pseudoplasticasticsity, ndiko kuti, shear inotetepa, uye yakakodzera kuti zviitiko zvekushandisa zvakaita sejasi, slurries, etc. iyo inoda manyoiro akanaka.
3. Thermal Glation
HpMC kana ichipiswa mumvura, kujeka kwemhinduro kuderera kunoderera uye gel inoumbwa pane imwe tembiricha. Mushure mekutonhora, iyo gel nyika ichadzokera kumhinduro. Mhando dzakasiyana dzeHPMC ine dzakasiyana tembiricha, kazhinji pakati pe50 ne55 ° C. Ichi chivakwa chinonyanya kukosha pakushandisa sekuvaka moter uye mishonga yemishonga.
4. Svomukati chiitiko
Nekuti HPMC mamorekuru ane hydrophilic uye hydrophobic mapoka, vanoratidza zvimwe zviitiko zvepamhepo uye vanogona kutamba vanokonzera, kuparadzira uye kusimbisa basa. Semuenzaniso, mumabhonzo uye emulsions, HPMC inogona kuvandudza kugadzikana kwe emulsion uye kudzivirira iyo singimentation yezvikamu zvehuni.
5. Hygroscopicity
HPMC ine imwe hygroscopicity uye inogona kutora unyoro munzvimbo ine humid. Naizvozvo, mune zvimwe zvekushandisa, kutariswa kunofanirwa kubhadhariswa kurongedza chisimbiso kudzivirira kunyorova uye kuunganidzwa.
6. Firimu-kugadzira pfuma
HPMC inogona kuumba firimu rakaoma uye rinojeka, iro rinoshandiswa zvakanyanya mukudya, mushonga (wakadai sekukanda vamiririri) uye kuungana. Semuenzaniso, muindasitiri yemishonga, HPMC firimu rinogona kushandiswa sehomwe yekuvandudza kudzikamisa kugadzikana kwezvinodhaka uye kudzora kusunungurwa.
7. Biocomprifilibility uye kuchengeteka
HPMC isiri-ine chepfu uye isina kukuvadza, uye inogona kuve yakachengeteka nemuviri wemunhu, saka inoshandiswa zvakanyanya muminda yemushonga uye chikafu. Semhando yemishonga yemishonga, inowanzoshandiswa kubereka mahwendefa ekusimudzira, capsule shells, nezvimwe.
8. PH Kugadzikana kweSolution
HPMC yakagadzikana mumhando ye3 kusvika ku11, uye haina kunyatso nyorwa kana kuti yakavezwa neAcid neAlkali
9. Kupesana kwemunyu
HPMC Solution yakamanikidzwa kune inorganic salts uye haina kunyatsogadzirirwa kana kusashanda nekuda kwekuchinja kweIion
10. Kugadzikana kwekutonga
Simbacelcele®HPMC ine yakanaka kugadzikana mune yakanyanya tembiricha nzvimbo, asi inogona kushatisa kana discolor kana ichiratidzwa kupisa kwakanyanya kwenguva yakareba. Iyo inogona kuramba ichiramba kuita zvakanaka mukati meimwe tembiricha yekupisa (kazhinji pazasi 200 ° C), saka yakakodzera kune yakakwirira-tembiricha yekugadzirisa.
11. Kugadzikana kwemakemikari
Hpcyakagadzikana kwazvo kujekesa, oxidants uye zvakafanana makemikari, uye haikanganiswa nyore nyore nezvinhu zvemakemikari zvekunze. Naizvozvo, inogona kushandiswa muzvigadzirwa izvo zvinoda kuchengetedza kwenguva refu, sekuzvivakwa nemishonga nemishonga.
HydroxyPropyl methylcellose inoshandiswa zvakanyanya mune akawanda maindasitiri nekuda kwekushamwaridzana kwayo kwekunyora, kuremedza Mune indasitiri yekuvaka, inogona kushandiswa sekement dol thickener; Muindasitiri yechechi yechechi, inogona kushandiswa semishonga yemishonga; Muindasitiri yechikafu, icho chinowanzoitika chikafu chinowedzera. Iyi ndiyo nzvimbo dzakasiyana dzemuviri dzinoita hpmc chinhu chakakosha chinoshanda polymer.
