Cov khoom lag luam
HydroxyPropyyl methylulose (hydroxypropylulose, HOLMC) yog cov cellulose cellulose los ntawm kev hloov kho cov nqaij ntawm ntuj (etherification). Nws muaj cov yam ntxwv ntawm cov dej solubility, zaj duab xis-ua cov cuab yeej, thiab tau kho viscosity, thiab cov khoom siv tsev, tshuaj kho tsev, txhua hnub tshuaj thiab lwm yam kev lag luam.
HPMC Cov Txheej Txheem Ntau Lawm
1. Cov Khoom Siv Khoom Muag:
- Cellulose (ntoo pulp \/ paj rwb) yog alkalized nrog naoh daws los tsim alkali cellulose.
2. Otherification tiv thaiv:
- Rov qab nrog methyl chloride (methylation) thiab propylene oxide (hydroxypropation) hauv autoclave.
3. Purification:
- nruab nrab thiab ntxuav kom tshem tawm cov khoom lag luam (xws li nacl), thiab zuaj tom qab ziab.
4. Kev kawm tiav:
- cais cais raws li cov tsis xws li viscosity thiab degree ntawm kev hloov pauv (xws li cov zaub mov qib, khoom noj khoom haus qib, muaj qeb kawm).
Daim ntawv thov tseem ceeb
1. Kev lag luam kws tshuaj) (cov ntawv thov tseem ceeb)
- Ntsiav tshuaj txheej txheem:
- Ua ib txheej sib cais (noo noo-pov thawj, tsw qab-masking) lossis ib zaj duab xis tso tawm (xws li HPMC K series).
- Kev npaj siab-tso tawm:
- Ua cov txheej txheem gel hauv kev sib cuag nrog dej, maj mam tso cov tshuaj (xws li cov tshuaj ntsuam metformin).
- Qhov muag paug \/ khoom muag muag muag:
- Raws li cov roj nplua nyeem thiab cov tuab tuab (xws li HPMC E5).
- Binder:
- Txhim kho hmoov zoo khi hauv cov granulle ntub (hloov PvP).
2. Lub tsev cov ntaub ntawv
- xis mas cug additives
- Txhim kho cov dej tuav thiab tiv thaiv cov khoom siv los tiv thaiv saging (xws li cov nplais nplaum, putty hmoov).
- Gypsum-based khoom:
- Sijhawm ncua sijhawm thiab txhim kho kev ua haujlwm.
* 3. Kev Lag Luam Khoom Noj Khoom Haus (E464)
- Thickener \/ stabilizer:
- siv hauv cov mis nyuj khov, cov kua nplaum, nroj tsuag cov zaub mov, thiab lwm yam.
- Neeg tsis huv tau hloov:
- Simulate qhov saj ntawm nqaij (xws li cov nqaij dag dag).
4. Tshuaj Txhua Hnub thiab Kev Kho Mob
- Zawv plaub hau \/ Da Dej Gel:
- thickening thiab ncua tawm cov lus (xws li txhuam).
- Tshuaj txhuam:
- txhim kho paste stability.
5. Lwm cov ntawv thov
- Ceramic ci: Cov neeg sawv cev
- 3 d luam tawm: bio-ink matrix
- Yob Ntswg: Rov Kho Mob Luam Yeeb
Cov khoom lag luam zoo
- Zoo biocompatibility zoo, kev nyab xeeb thiab tsis muaj tshuaj lom.
- Kho tau cov viscosity carcosity kom tau raws li tau raws li cov kev xav tau sib txawv.
- Muaj cov ntsev tsis kam, haum rau lub zog ionic lub zog ib puag ncig.
Kev ua lag luam thiab ib puag ncig cov qauv
- Loj hlob ntawm cov kws tshuaj ntsuam xyuas: Lub ntiaj teb muaj kev lag luam tawm hauv ntiaj teb tsav tsheb HPMC (txhua xyoo kev loj hlob ntawm kwv yees li 5%).
- Allod Alternativ: Qee cov tuam txhab tshawb txog cov neeg ua haujlwm ntawm cellulose bio-based (txo qis kev vam khom rau tom ntej oxide).
- Suav teb cov khoom lag luam: ntau dua 70% ntawm lub ntiaj teb HPMC yog tsim nyob rau hauv Suav teb (Shandong Heda, Lotte Tshuaj, thiab lwm yam).
