Kudakemurwa kwa hydroxyPropyl methylcellse (HPMC, HydroxyPropyl methylcellse) bigira ingaruka kubintu byinshi, harimo ibidukikije byumubiri hamwe nibidukikije. Ibi bintu bifite akamaro gakomeye kubisabwa na HPMC nibikorwa byayo muri farumasi, ibiryo, kubaka nizindi nganda.
1.. Imiti yumubiri na shimi
1.1 Uburemere bwa molekile
Uburemere bwa moleki ya HPMC ni ikintu cyingenzi kigira ingaruka ku kuntu kwikesha. Mubisanzwe, nini cyane uburemere bwa molekile, buhoro buhoro igipimo cyo gusebanya. Ni ukubera ko uburemere bunini bwa molecular butera iminyururu ndende ya molecular, yongera ubwitonzi n'imikoranire hagati ya molekile, bityo itinda inzira yo kuvuka. Ibinyuranye nibyo, HPMC ifite uburemere buto bwa molecular irashonga vuba, ariko ibisubizo byayo birashobora kuba byo hasi, bigatuma bidakwiriye gusaba.
1.2 Urwego rwo gusimbuza
Urwego rwo gusimbuza HPMC (ni ukuvuga urwego rwo gusimbuza uburyo na hydroxyPropoplexy) kandi rugira ingaruka ku buryo bugaragara cyane. HPMC ifite urwego rwo hejuru rwuburyo na hydroxypropyxy mubisanzwe ifite byinshi byonyine mumazi kuko aba basimbuye bashobora kongera hydrophilicity ya molekile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile no guteza imbere hydkile. Ariko, gusimburwa gukabije birashobora gutuma kugabanuka mubikewe bya HPMC mubintu bimwe na bimwe, bifitanye isano na polarity yimikoranire nubushake.
1.3 Ingano
Ingano ya HPMC ifite ingaruka zitaziguye ku gipimo cyayo. Ingano ntoya, nini cyane ahantu runaka ku bunini ku gice, kandi agace kagaragaye ko kwiyongera kwiyongera, bityo twihutisha inzira yo kuvugurura. Kubwibyo, HPMC muburyo bwiza bwifu mubisanzwe irashonga byihuse kuruta muburyo bukomeye.
2. Ibisabwa
2.1 Ubwoko bwa Solvent
Kukesha kwa HPMC biratandukanye cyane muburyo butandukanye. HPMC ifite neza mumazi, cyane cyane amazi ashyushye. Ibiti bidafite inzitizi nka Ethanol, Esylene Glycol, Ethylene Glycol, nibindi arashobora no gusezerera HPMC, ariko umuvuduko wo gusebanya kandi uke cyane munsi y'amazi. Muburyo budasanzwe, kwikebagura biterwa nibice byibigize hamwe nibikorwa byabo na HPMC.
2.2 Ubushyuhe
Ubushyuhe bugira ingaruka zikomeye kubake cyane hpmc. Muri rusange, HPMC irashonga buhoro buhoro mumazi akonje, ariko uko ubushyuhe bwiyongera, urugero rwibicapo rwiyongera, kandi rukora neza mumazi ashyushye ya 40-50 ° C. Ariko, ku bushyuhe bwinshi (mubisanzwe hejuru ya 70 ° C), HPMC irashobora kugwa cyangwa ngo ikore gel, ifitanye isano nimpinduka mumiterere ya termodynamic hamwe nimiterere yumuti.
2.3 PH agaciro
Kudakemurwa na HPMC birahagaze neza mubihe bitandukanye bya PH, ariko bikabije PH (nka aside ikomeye cyangwa alkali) birashobora kugira ingaruka kukeshawe no gutuza. HPMC muri rusange ifite ibyokuntu byiza bitabogamye cyangwa bitabogamye PH.
3. Impamvu y'ibidukikije
3.1 Ibihe byiza
Umuvuduko wubushake nuburyo bigira ingaruka zikomeye kumuvuduko wa HPMC. Gushishikazwa neza birashobora guteza imbere umubano hagati ya HPMC na Solvent kugirango wirinde gushiraho ihukwa, bityo twihutisha inzira yo kuvugurura. Kubyutsa vuba birashobora gutera ibibyimba byo gukora, bigira ingaruka ku bumwe bwigisubizo.
3.2 Inyongera
Izindi nguzanyo mu gisubizo, nk'ubwinyungo, amashanyarazi, surfactant, n'ibindi, bizagira ingaruka ku bushobozi bwa HPMC. Kurugero, umunyu runaka urashobora guteza imbere iseswa rya HPMC, mugihe ibintu byinshi bya electrolytes bishobora gutera imvura cyangwa uruzitiro rwa HPMC. Ongeraho ibisigisiwe birashobora kunoza ibibazo bya HPMC mubintu bimwe bitari byiza kandi byoroshye imikorere yumuti.
4. Ibitekerezo byo gusaba
4.1 Inganda za farumasi
Mu nganda za farumasi, HPMC ikoreshwa cyane nkibintu bya matrix mugihe cya mari ya matric mu myiteguro ihamye, kandi iraba igira ingaruka ku buryo butaziguye igipimo cyo kurekura na bioatseilability y'ibiyobyabwenge. Kubwibyo, kugenzura ibiro bya molekili, urwego rwo gusimbuza no gusebanya ibintu bya HPMC ni ngombwa kugirango witegure imyiteguro ifatika kandi ihamye.
4.2 Inganda zibiri
Mu nganda zibiribwa, HPMC ikoreshwa nkuwabyimbye, Stabilizer na Emalisiier. Kudakemukira bisobanura gutatanya, imiterere no gutuza mu biryo. Muguhindura imiterere yo gusebanya, ingaruka zisaba HPMC mubiryo zirashobora kungurizwa.
4.3 Inganda zubwubatsi
Mu bikoresho byo kubaka, HPMC ikoreshwa nk'abakozi bagumana amazi, ubumwe bwamazi, ubumwe na bunder, kandi kwihuta bigira ingaruka kumikorere yubwubatsi nuburyo bwa minisiteri bwa nyuma, amababi n'ibindi bicuruzwa. Guhindura ibisabwa na sisitemu yo gusaba HPMC birashobora kunoza ingaruka zo gukoresha no kuramba kubikoresho.
Kudakemurwa na HPMC bigira ingaruka kumiterere yumubiri na shimi nko muburemere bwa molecular, urwego rwo gusimbuza, hamwe nubunini bwamafaranga, ubushyuhe, agaciro ka PH hamwe nibikoresho bidukikije. Mubikorwa bifatika, kwikebagura n'imikorere mikorere ya HPMC birashobora kunonosorwa neza muguhitamo no kugenzura ibyo bintu ukurikije ibishoboka byihariye nibidukikije. Gusobanukirwa byimbitse kuri izi ngingo bizafasha kunoza ingaruka zisaba HPMC mu nganda zinyuranye kandi zitanga inkunga yo guhanga udushya mu nzego zifitanye n'amahanga.
