Itandukaniro mumitungo yumubiri na shimi hagati ya HPMC na hemc

HydroxyPropyl MethylcellUlose (HPMC) na hydroxyyethyl methylcellsailose (hemc) ikoreshwa na selile yakoreshwaga cyane mu nganda zitandukanye kubera imiti yabo itandukanye. Nubwo imiyoboro yabo isa, hari itandukaniro ryingenzi mumitungo yabo ituma ikwiye kubisabwa bitandukanye.

1.Kwica imiterere:

HPMC na hemc biva muri selile, polymer karemano. Itandukaniro nyamukuru riri mu basimbuye rifatanije na selile. Muri HPMC, abasimbuye barimo methyl na hydroxyproppopyl, mugihe muri hemc, abasimbuye barimo methyl na hydroxxiebethyl. Ibisimbuza birashobora kugira ingaruka kumiterere rusange ya erether.

2. Kudakemurwa:

Itandukaniro rikomeye hagati ya HPMC na hemc nimyitwarire yabo yonyine. HPMC yerekana neza cyane mumazi akonje ugereranije na hemc. Uyu mutungo ningirakamaro kubisabwa bisaba gusenya byihuse cyangwa gutanyagura polymers, nko mumiti yimodoka.

3. Kugumana amazi:

HPMC muri rusange ifite ubushobozi bwo kugumana amazi kuruta Hemc. Uyu mutungo ni ushishikaye muri porogaramu nka sisitemu ishingiye kuri sima, aho hanagarikwa amazi mu mazi kugenzura inzira yo gukumira no guteza imbere ibikorwa.

4. Ubushyuhe bwa Gel:

Ubushyuhe bwa dolling nubushyuhe burimo igisubizo cyangwa gutatanya impinduka muri gel. HEMC muri rusange ikora gels kubushyuhe bwo hasi kuruta HPMC. Uyu mutungo urashobora kuba mwiza mubisabwa nkibicuruzwa byibiribwa, aho ubushyuhe bwo hasi busabwa bushobora gukenerwa kugirango bikoreshwe.

5.Imitungo yimiterere:

HPMC na hemc bigira uruhare mumyitwarire yuburyo bwimiterere cyangwa gutandukana. Ariko, ingaruka zabo kuri viscosity hamwe nimyitwarire yoroheje yo gukuramo inkono irashobora gutandukana. HEMC muri rusange itanga ubushyuhe bwo hejuru mugihe cyo hasi, bigatuma habaho porogaramu zimwe zisaba ibisubizo byibanze.

6. Gushiraho firime:

HPMC na hemc irashobora gukora firime zoroheje iyo zishyizwe hejuru. Ukurikije selile ether yakoreshejwe, firime zerekana ibintu bitandukanye. Filime ya HPMC muri rusange zirahinduka cyane, mugihe firime ya hemc iratontomera. Uyu mutungo ugira ingaruka kumikoreshereze yabo, uhimbye nibindi bikorwa byo gushinga film.

7. Guhuza nibindi bice:

Guhitamo hagati ya HPMC na HEMC nayo biterwa no guhuza nibindi bigo. Kurugero, HPMC ikunze gushimishwa muri farumasi kubera guhuza nibikoresho bitandukanye bikora, mugihe hemc ishobora gutoranywa kubisabwa byihariye bishingiye kubiranga ihuza.

8. Umutekano mu bushyuhe:

Abashiraho seliki bombi bagaragaza umutekano mwiza wubushyuhe, ariko ubushyuhe batesha agaciro bushobora gutandukana. HPMC ikunda kugira umutekano muremure ugereranije na hemc. Iyi mikorere ni ngombwa mubisabwa aho guhura nubushyuhe bwo hejuru busuzumwa.

Nubwo HPMC na hemc basangiye selile isanzwe, ibisimbura byihariye bya shimi bivamo mumitungo itandukanye yumubiri na shimi. Gusobanukirwa itandukaniro ni ngombwa guhitamo selile ikwiye kugirango usabe icyifuzo runaka, haza neza imikorere myiza n'imikorere. Guhitamo hagati ya HPMC na HEMC biterwa nibisabwa byihariye byo gusaba, kuva muri farumasi hamwe nibikoresho byubwubatsi kubiryo nibikorwa.
