Ungayigcwalisa kanjani i-HPMC?

I-Dilution ye-HPMC (Hydroxypropyl Methylcellulose) imvamisa ukuguqula ukugxila kwayo ukuze kuvumelane nezidingo zohlelo lokusebenza ezihlukile. I-HPMC iyingxenye ye-polymer encibilikayo esetshenziswa kabanzi ezimbonini zezemithi, zokwakha, zokudla kanye nezimboni zezimonyo.

(1) Ukulungiselela
Khetha izinhlobonhlobo ze-HPMC ezifanele:

I-HPMC ine-viscosities ehlukile nama-sonibip. Ukukhetha izinhlobonhlobo ezifanele kungaqinisekisa ukuthi ikhambi elihlanjululwe lihlangabezana nezidingo zohlelo lokusebenza.
Lungiselela amathuluzi nezinto zokwakha:

I-HPMC powder
Amanzi anciphile noma amanzi e-deionized
I-Magnetic Stirrer noma i-Stirrer ebhukwayo
Ukulinganisa amathuluzi afana nama-cylinder alinganisa kanye nezinkomishi zokulinganisa
Iziqukathi ezifanele, njengamabhodlela engilazi noma amabhodlela epulasitiki.

(2) Izinyathelo ze-Dilution
Isisindo se-HPMC ye-HPMC:

Ngokweqoqo okumele lihlanjululwe, lilinganise ngokunembile inani elidingekayo le-HPMC powder. Imvamisa, iyunithi lokuhlushwa ngamaphesenti wesisindo (W / W%), njenge-1%, 2%, njll.
Engeza amanzi:

Thela inani elifanele lamanzi ancishisiwe noma ahleliwe esitsheni. Inani lamanzi kufanele linqunywe ngokuya ngezidingo zokuhlushwa zesisombululo sokugcina.
Ukungeza i-HPMC powder:

Faka i-HPMC enesisindo se-hpmc ngokulinganayo emanzini.

Kuvusa nokuncibilika:

Sebenzisa isigqugquzeli kazibuthe noma umgqugquzeli wesandla ukuvuselela ikhambi. I-Stiring ingasiza i-puzle ye-HPMC ichithe ngokushesha nangokulinganayo ngokulinganayo. Ijubane elishukumisayo nesikhathi kudinga ukulungiswa ngohlobo nokuhlushwa kwe-HPMC. Ngokuvamile, isikhathi esinconyiwe sokuvuselela yimizuzu engama-30 amahora amaningi.

Emi futhi edelela:

Ngemuva kokuvusa, vumela ikhambi limele isikhathi esithile, imvamisa ihora eli-1 libe amahora angama-24. Lokhu kuvumela ama-bubble kwikhambi ukukhuphuka futhi anyamalale, aqinisekise ukufana kwesixazululo.

(3) Ukuqapha

Ijubane elishukumisayo nesikhathi:

Isikhathi esisheshayo kanye nesikhathi esishukumisayo sokuchithwa kwe-HPMC kuthintwa ukubonwa kwayo nokushisa kwamanzi. Ngokuvamile ukukhuluma, ukubona okuphezulu i-hpmc ephakeme kudinga isikhathi eside esivusa amadlingozi.

Ukushisa kwamanzi:

Kusetshenziswa amanzi afudumele (anjenge-40 ° C-60 ° C) angasheshisa ukuchithwa kwe-HPMC, kepha qaphela ukuthi ungasebenzisi izinga lokushisa kakhulu ukuze ugweme imiphumela yezakhiwo ze-HPMC.

Ukuvimbela Ukuqothuka:

Lapho ungeza i-HPMC powder, zama ukugwema ukuhlangana. Ungaqala uhlanganise i-powder ye-HPMC ngenani elincane lamanzi libe yi-slurry, bese kancane kancane uyingeze emanzini asele ukunciphisa i-agglomeration.
Isitoreji:

Isixazululo se-HPMC esihlanjululwe kufanele sigcinwe esitsheni esihlanzekile, esivaliwe ukugwema umswakama noma ukungcoliswa. Izimo zokugcina kufanele ziguqulwe ngokuya ngezidingo zokusetshenziswa kanye nezimo zemvelo ze-HPMC.
Ukuphepha:

Ngesikhathi sokusebenza, imishini efanelekile yokuzivikela efana namagilavu ​​kanye nama-masks kufanele agqoke ukugwema ukuxhumana ngqo ne-HPMC powder nesixazululo esigxile.

Ngokusebenzisa lezi zinyathelo ezingenhla, ungawitha i-HPMC njengoba kudingeka ukuqinisekisa ukusebenza kwayo nokuqina kwayo kuzicelo ezihlukile. Isimo ngasinye sohlelo lokusebenza singaba nezidingo ezihlukile, ngakho-ke kubaluleke kakhulu ukuqonda nokuthobela amazinga athile okusebenza nezidingo.
