Senyanzvi yekugadzira HPMC, tinotenda kuti Hydroxypropyl Methyl Cellulose (HPMC) ndeimwe yeanonyanya kushandiswa uye akavimbika cellulose ethers anoshandiswa mumaindasitiri akasiyana anovimba nemakemikari ekuwedzera kune chimwe chinangwa.
Chimwe chezvinhu zvakakosha zveHPMC kugona kwayo kuchengetedza mvura. Izvi zvinoita kuti ive yakanaka kune akasiyana siyana ekushandisa mukuvaka, zvizorwa, zvemishonga uye maindasitiri ezvekudya.
Nekudaro, kunyangwe paine akawanda mabhenefiti eHPMC, kugona kwayo kuchengetedza mvura kunogona kukanganiswa nezvinhu zvakati wandei, izvo zvinogona kukanganisa kuita kwayo. Pazasi pane zvimwe zvinowanzoitika zvinokanganisa simba rekuchengetedza mvura reHPMC.
1. Tembiricha
Tembiricha ndechimwe chezvinhu zvakakosha zvinokanganisa kuchengetedza kwemvura kweHPMC. Sezvo tembiricha ichiwedzera, HPMC inowanzorasikirwa nekukwanisa kwayo kuchengetedza mvura. Naizvozvo, kana tembiricha yakawandisa, iyo HPMC inogona kusachengeta mvura yakakwana yekushandiswa kwayo.
Naizvozvo, zvinokurudzirwa kuchengetedza HPMC munzvimbo inotonhorera uye yakaoma kudzivirira kuderedzwa kwekuita nekuda kwekuratidzwa kwekupisa.
2. Humidity
Humidity ndiko kuwanda kwemvura iri mumhepo. HPMC inotora hunyoro kubva mumhepo, iyo inokanganisa kugona kwayo kubata mvura. Kana hunyoro hwakanyanya, HPMC inotora mwando wakawandisa kubva kumhepo, zvichikonzera matambudziko akaita secaking uye kuomesa.
Naizvozvo, zvakakosha kuchengeta HPMC mumidziyo isingapindi mhepo kudzivirira kusangana nehunyoro nehunyoro.
3. pH
Iyo pH kukosha kwenzvimbo inozokanganisawo simba rekuchengetedza mvura reHPMC. HPMC inoshanda zvakanyanya munzvimbo ine acidic zvishoma kana kwayakarerekera pH nharaunda. Nekudaro, munzvimbo dzine acidic zvakanyanya kana alkaline, huwandu hwekuchengetedza mvura hweHPMC huchadzikiswa zvakanyanya.
Naizvozvo, zvakakosha kuve nechokwadi chekuti nharaunda inoshandiswa HPMC iri mukati meiyo inogamuchirwa pH renji.
4. Kukura kwechikamu
Iyo particle size yeHPMC inokanganisawo simba rekuchengetedza mvura. Zvimedu zvidiki zvinowanzova nepamusoro penzvimbo kusvika kuhuwandu hwehuwandu, izvo zvinogona kutungamirira kuwedzera kwekuchengetedza mvura.
Naizvozvo, kune maapplication anoda yakakwirira yekuchengetedza mvura, diki diki saizi HPMC inokurudzirwa.
5. Dissolving speed
The dissolution rate yeHPMC inokanganisawo simba rekuchengetedza mvura. HPMC ine mwero inononoka yekunyungudika inoita kunge iine huwandu hwepamusoro hwekuchengetedza mvura kupfuura HPMC ine kukurumidza kunyungudika mwero.
Naizvozvo, kune maapplication anoda yakakwira yekuchengeta mvura, HPMC ine inononoka kunyungudika mwero inokurudzirwa.
mukupedzisa
Muchidimbu, semugadziri weHPMC, isu tinoona simba rekuchengetedza mvura reHPMC seimwe yemabhenefiti ayo akakosha. Zvisinei, zvakakosha kufunga nezvezvinhu zvakasiyana-siyana zvinokanganisa kukwanisa kwayo kubata mvura.
Naizvozvo, zvakakosha kuve nechokwadi chekuti HPMC inochengetwa munzvimbo inotonhorera, yakaoma, mumudziyo usina mhepo, munzvimbo ine pH renji, ine diki diki saizi uye inononoka kunyungudika mwero weiyo yakakwana kuchengetedza mvura.
Nekutora matanho aya, HPMCs inogona kuita zvakanaka mumhando dzakasiyana dzekushandisa.
