HydroxyPropyl Methylcellsellse (HPMC) ni ikigo cyingenzi cyamazi cya polymer hamwe nubukorikori. Bikoreshwa cyane mubuvuzi, kubaka, ibiryo, kwisiga nizindi nzego. HPMC ifite imitungo idasanzwe yumubiri nu mitima binyuze muburyo bwo guhindura imiti yimiterere ya selile, bihuye nibikenewe bitandukanye.
1. Imiterere ya molekile hamwe numutungo
Imiterere ya HPMC igizwe na skeleton ishingiye kuri selile hamwe nabasimbuye zitandukanye (hydroxyPropyl na methyl). Binyuze mu guhindura imiti, amatsinda ya hydroxyPropyl na methyl yitangijwe muri molekile za HPMC, ziyiha amazi, kubyimba, gushiraho film nibindi bintu. Kubera imiterere yimiti ya HPMC, ntabwo yashonga mumazi na kama, ariko irashobora gukora igisubizo cyiboneye mumazi.
Itsinda ryabo rya hydroxyroppoyl ryiyongera hydrophilicity, mugihe itsinda rya methyl ryongerera hydrophobicity. Muguhindura ikigereranyo cya aba basimbuye bombi, amazi menshi, vicosity hamwe nundi mubiri na shimi ya HPMC birashobora guhinduka kugirango bahuze ibikenewe mubisabwa.
2. Kukemera no kurya
HPMC ifite uburemere bwiza, cyane cyane iyo ashonga mumazi ashyushye, bizahita bikora igisubizo kimwe. Ifite ubushobozi bukomeye bwo kurya kandi birashobora gukuramo amazi kugirango ubyimbye kandi ukore igisubizo cya colloidal gihamye. Ibi bigira HPMC ikoreshwa cyane mubahozeho, abigabye, emadizers, kumenyekanisha hamwe nindi mirimo, cyane cyane mu kurekura ibiyobyabwenge, kwitegura no gutegura ibiryo.
Mu nganda z'imiti, HPMC ikoreshwa kenshi gutegura imyiteguro y'ibiyobyabwenge, ishobora kugenzura neza ibiyobyabwenge. Kukegura no hydration bishoboza gushonga mu gitabo cya Gastrointestinal, birekura ibiyobyabwenge buhoro buhoro, hanyuma ugabanye ibiyobyabwenge.

Ikintu kigaragara cya HPMC kibyibushye. Ibyatsi byo gukemura HPMC bifitanye isano rya bugufi no kwibandaho, uburemere bwa molecular nurwego rwa hydtion. Ibiro byinshi byo mu modoka HPMC Igisubizo kinini kandi kibereye gusaba gisaba ruswa yo hejuru, nko kumenza, amababi, ibikoresho, n'ibindi, n'ibindi.
HPMC ifite kandi imitungo. Iyo kwibanda ku gisubizo cya HPMC ari hejuru, birashobora gukora gel mu mucyo, ari ingenzi cyane mu rwego rw'umuti, cyane cyane mu gutegura ibiyobyabwenge byakomejwe na Gel.
4. Guhagarara no Antioxident Ibintu
HPMC ifite imiti myiza yimiti kandi irashobora kwihanganira indangagaciro nini ya PH (muri rusange 4 kugeza 10). Kubwibyo, irashobora gukomeza imiterere n'imikorere muri aside nyinshi zitandukanye na alkaline. Ugereranije nundi bikomoka kuri selile, HPMC ifite imiterere ikomeye Antioxident kandi irashobora gukoreshwa muburyo butandukanye bwo kubungabunga.
Iki kintu gikora imiti gikora HPMC ikoreshwa cyane mubiryo byibiribwa, kwisiga hamwe nimyiteguro ya farumasi. Kurugero, mu nganda zibiribwa, HPMC ikoreshwa nka EmulsiFier na Trickener kugirango batezimbere imiterere kandi ituze kubicuruzwa.
5. BiocompUbility n'umutekano
HPMC, nka polymer-polymer, ifite biocompata nziza kandi niyo ikoreshwa cyane muri farumasi, ibiryo nibihingwa. HPMC ntabwo yinjiye rwose mumubiri, ariko nka fibre yoroheje, isohoka binyuze muri sisitemu yo gutekesha kandi muri rusange ifatwa nkibintu bitari uburozi kandi bidakabara. Bikoreshwa kenshi nkubuntu muri sisitemu yo gutanga ibiyobyabwenge kugirango afashe kurekura ibiyobyabwenge muburyo bukabije kandi buhamye.
Nkibiryo byongeweho, HPMC yemejwe na komisiyo ya Codex alimentarius nkibintu byiza byo gukoresha. Gusaba kwayo bifatwa nkumutekano kandi bitagira ingaruka kumubiri wumuntu.
6. Imirima isaba
6.1 Inganda za farumasi
Mu myiteguro ya farumasi, HPMC ikoreshwa cyane nka Thickener, Emulsifuer, Stabilizer na Udutwara. Muburyo bwo gutanga umunwa, HPMC ikunze gukoreshwa muri capsules, ibinini n'imyiteguro ihamye. Bitewe na biocompat yihariye kandi bihinduka kuranga ibintu byinshi mugutegura ibiyobyabwenge bitandukanye, cyane cyane mugutezimbere ibiyobyabwenge byakomeje.
6.2 Inganda zibiri
Mu nganda zibiribwa, HPMC ikoreshwa mubyimbye, kubangamira, kuzenguruka, gushiraho film hamwe nibindi bintu. Bikunze gukoreshwa mubicuruzwa bitetse, ibinyobwa, ibiryo byakonje, byongeramo hamwe na sosiki. HPMC irashobora kunoza neza uburyohe nuburyo bwo kurya no kwagura ubuzima bwibiryo.
6.3 kwisiga no kwita ku muntu ku giti cyabo
Mu murima wo kwisiga, HPMC ikunze gukoreshwa nka Thickener na Emalpiire mubicuruzwa bita byita ku ruhu, Shampoo, Cal, amenyo, kwisiga n'ibindi bicuruzwa. Ifite uruhu rwiza, irashobora kunoza ihumure no gutuza kubicuruzwa, kandi ntabwo byoroshye kurakaza uruhu mugihe cyo gukoreshwa.
6.4 Porogaramu yo kubaka hamwe ninganda
Mu nganda zubwubatsi, HPMC ikoreshwa nkubwinshi mu bikoresho byo kubaka nka cement mirtar, tile imeza, hamwe no gutora urukuta. Irashobora kuzamura umusaruro n'amazi mugihe cyo kubaka, kongera ibikoresho byibikoresho, no kunoza imbaraga no kuramba nyuma yo gukama.
Nkibintu byingenzi bya polymer, HPMC ifite ibintu bitandukanye byumubiri nudushimaji, nkamazi meza yoroheje, kubyimba, gushikama no bioquatishe. Umubare munini wa porogaramu urimo imiti, ibiryo, kwisiga, kubaka n'izindi nganda, bitanga imirimo yo kugereranya no guhitamo imikorere y'ibicuruzwa muri iyi nzego. Mugihe kizaza, nkuko abantu babisabye bikunze kubaho ibidukikije, bifite ubuzima bwiza kandi bikora bikomeje kwiyongera, ibyifuzo bya HPMC bizakomeza kuba ibuza.
