Hydroxyprupyl methylcellose (HPMC)uyeMethylcellose (mc)Vese vari vaviri cellose vanobva vanowanzo shandiswa mune dzakasiyana-siyana maindasitiri, kusanganisira mishonga yemishonga, chikafu, zvizaradzi, uye kuvaka. Pasinei nezviri kufanana, izvi zviviri zvinoshandiswa nemakemikari akasiyana uye zvikumbiro.
1. Chemical chimiro
Vese HPMC uye MC vaine cellulose Derivatives, asi musiyano wakakosha wakarara mumapoka emakemikari akabatanidzwa kune iyo cellulose backbone.
Methylcellose (mc): Izvi zvinoumbwa nemethylation of cellulose. Muchiitiko ichi, methyl mapoka (-ch3) akabatanidzwa kune iyo hydroxyl mapoka ema cellulose mamorekuru. Iyo methylation degree kazhinji inosiyana pakati pe20-30%, zvichienderana negiredhi reMC, iro rinopesvedzera iyo solubility uye zvimwe zvinhu.
Hydroxyprupyl methylcellose (HPMC): Kimicell®hpmc ndeyekuwedzera kuomarara. Kuwedzera kune methyclation, iyo zvakare inoisa hydroxyprusation. Hydroxyprusypropyl mapoka (-ch2chohch3) anounzwa kune iyo cellulose Molecule, pamwe chete ne methyl mapoka. Iyo hydroxyprorlation degree uye methylation degree reHPMC inogona kusiyana zvakanyanya, iyo inopa kune akasiyana-siyana eHPMC mamakisi ane maitiro akasiyana.
| Chimiro | Methylcellose (mc) | Hydroxyprupyl methylcellose (HPMC) |
| Chemical chimiro | Methylation of cellulose | Methylation uye hydroxyprupropropylation ye cellulose |
| Mashandiro emapoka | Methyl mapoka (-ch3) | Methyl mapoka (-ch3) + hydroxypruppropyl mapoka (-ch2chohch3) |
| Degree rekutsiva (DS) | 20-30% methylation | Inosiyana, ine methyl uye hydroxypruppropyl yekutsiva mazinga anogadziriswa |
2. Solubility
Solubility ndechimwe chezvinhu zvakakosha kana uchienzanisa MC uye HPMC. Iyo solubility yemaviri aya mheremalose derivatives inoenderana neiyo degree rekutsiva uye chaiyo yekuumbwa kwezvinhu.
Methylcellose (mc): MC inonyungudika mumvura inopisa asi inogadzira gel pane inotonhorera. Iyi yakasarudzika midziyo yekuumba maGels kana ichipiswa uye inodzedzereka kumamiriro ekunze pane kutonhora ndeimwe yehunhu hwakakosha hweMC. Izvo zvinosemesa mumvura inotonhora, asi nyarara mumvura inopisa pamusoro peimwe tembiricha chikumbaridzo (50-7 ° C), uye maitiro egwenzi anozvidzora.
Hydroxyprupyl methylcellose (HPMC): HPMC, kune rumwe rutivi, inonyudza mumvura inotonhora uye inopisa. Izvi zvinoita kuti zvinyatsoenzanisirwa zvinoenderana ne mc. Iyo solubility yeHPMC inokurudzirwa nemhando yekutsiva (iyo chiyero che methyl kuenda ku hydroxypruspropyl mapoka) uye giredhi rekusangana. Subtution Substitution madhigirii anowanzoita kuti HPMC ive yakawanda mumvura pakudziya kwakadzika.
| Solubility | Methylcellose (mc) | Hydroxyprupyl methylcellose (HPMC) |
| Solubility mumvura | Nyura mumvura inopisa (gelation pakutonhora) | Nyura mumvura inopisa uye inotonhora |
| GENING PEST | Mafomu ane kutonhora | Haina kuumba gel, inoramba ichinyura pakupisa kwese |
3. Viscosity
Viscosity inotora basa rakakosha mune dzakawanda mashandisirwo, kunyanya mune maindasitiri emishonga uye ekudya.
Methylcellose (mc): Iyo viscosity yeKimacell®MC Solutions ari tembiricha-anotsamira. Mawisikoka anowedzera kana apiswa, uye zvinoratidza chinhu cheGenlenon. Dhigirii rekutsiva rinobata zvakare vhiza, vane yepamusoro substitution mazinga anowanzo kukonzera kuKekakwirira viscosity.
Hydroxyprupyl methylcellose (HPMC): HPMC inowanzove ine yakawanda yekuwirirana viscosity mbiri yakafananidzwa neMC. Iyo viscosity yeHPMC inokurudzirwa zvakare neiyo degree rekutsiva, asi rinoramba rakagadzikana kuwanda kweiyo tembiricha. Pamusoro pezvo, HPMC inogona kuve yakagadziriswa kuti ive nezvakasiyana zvevema visikoka, kubva kune yakaderera kusvika kumusoro, zvichienderana nechinangwa chakanangana.
| Viscosity | Methylcellose (mc) | Hydroxyprupyl methylcellose (HPMC) |
| Maitiro ekuvenga | Inowedzera nekudziya (gelation) | Yakasarudzika viscosity pane dzakasiyana tembiricha |
| Kutonga pamusoro peviscosity | Kushoma kutonga pamusoro peviscosity | Kutonga kukuru pamusoro peviscosity zvichibva pane giredhi uye kutsiva chikamu |
4. Zvishandiso
Zvese zviri zviviri MC uye HPMC inoshandiswa zvakanyanya mumishonga yechikadzi, chikafu, uye maindasitiri ezvekupedzisira, asi zvinhu zvakananga zveumwe neumwe zvinoita kuti zviite zvakakodzera zvimwe zvekushandisa.
Methylcellose (mc):
