HPMC (Hydroxypropyl Methyl Cellulose)naHPC (Hydroxypropyl Cellulose)byombi ni ibikomoka kuri selulosi, bikoreshwa cyane mu nganda zikora imiti, ibiribwa, ubwubatsi n'ubwiza. Nubwo byombi bisa mu ngingo zimwe na zimwe, biragaragara ko bitandukanye mu miterere ya shimi, imiterere y'umubiri n'iya shimi, gushonga no gukoreshwa.
1. Imiterere n'imiterere y'ibinyabutabire
HPMC ikorwa na methylation na hydroxypropylation bya cellulose karemano, kandi ikubiyemo methoxy (–OCH₃) na hydroxypropoxy (–OCH₂CHOHCH₃) muri molekile.
HPC iboneka binyuze muri hydroxypropylation ya selulose, kandi itsinda ryayo ry'ingenzi ni hydroxypropoxy (–OCH₂CHOHCH₃), idafite methoxy.
Kubera ko HPMC ifite itsinda ry’inyongera rya methoxy kurusha HPC, HPMC ikunda amazi cyane, mu gihe HPC ikunda amazi cyane. Byongeye kandi, uburemere bwa molekile ya HPMC busanzwe buri hejuru, mu gihe uburemere bwa molekile ya HPC bushobora kugenzurwa mu buryo bworoshye, ibi bigira ingaruka ku miterere y’ibinyabutabire n’imiterere y’ibinyabutabire byombi.
2. Imiterere y'amazi ashonga n'uburyo ashonga
HPMC ishongera mu mazi akonje kugira ngo ikore umuti wa colloidal ubonerana cyangwa ubonerana, ariko ntushongera mu mazi ashyushye. Kubwibyo, HPMC igomba gushongera mbere cyangwa gukwirakwizwa hakoreshejwe uburyo bwihariye muri bimwe mu bikorwa.
HPC ifite ubushobozi bwo gushonga neza mu mazi kandi ishobora gushonga mu mazi akonje no mu bintu bimwe na bimwe by’umwimerere, nka ethanol, methanol, nibindi, kandi ifite ubushobozi bwo gushonga no gukora filime.
HPMC ifite imiterere ya thermogel. Iyo ubushyuhe buzamutse, umuti ushobora gutandukana mu byiciro, mu gihe HPC ubusanzwe idakora thermogel, bityo HPC ikagira ubusugire bwiza mu bidukikije birimo ubushyuhe bwinshi.
3. Imiterere y'ubukana n'imiterere y'imitsi
HPMC ifite ubukana bwinshi kandi ikunze gukoreshwa nk'ikintu gikomeza ubukana, gitera imbaraga no gukora filime. Imiterere yayo ya rheological mu gisubizo cy'amazi yegereye cyane amazi ya pseudoplastic.
HPC ifite ubukana buke kandi ikwiriye cyane mu miti isaba ubushyuhe bwinshi, nk'imiti inyobwa n'ibikoresho byo gusiga.
4. Ahantu ho gushyiramo porogaramu
Bitewe n'itandukaniro ry'imiterere y'umubiri n'iya chimique hagati ya HPMC na HPC, bigira uruhare rutandukanye mu nganda n'ibicuruzwa bitandukanye:
Inganda z'imiti
HPMC ikoreshwa cyane cyane nk'igikoresho cyo gufunga, gikoreshwa mu gusohora imiti, gikoreshwa mu gutwikira ibinini bya farumasi, ndetse n'igice cy'igishishwa cya capsules zidafite ububobere. Imiterere yayo myiza yo gukora firime no gushonga kw'amazi bituma iba ikintu gikunzwe cyane mu gutegura imiti ikoreshwa mu gusohora imiti mu buryo buhoraho.
HPC ikoreshwa cyane cyane nk'ikintu gikuraho ubushyuhe, gifunga, gishongesha, kandi gifata ibinini, kandi ikwiriye kunoza uburyo imiti ishonga neza kandi iboneka neza. Byongeye kandi, HPC ikoreshwa cyane mu ikoranabuhanga ryo gusohora ubushyuhe bushyushye kurusha HPMC.
Inganda z'ibiribwa
HPMC ishobora gukoreshwa nk'umuti ukomeza ibiryo, ugabanya ibinure, ugabanya ibinure, n'umuti ugabanya ibinure mu mavuta atari ay'amata.
HPC ikoreshwa cyane cyane nk'umuti wongera ibiryo, ugabanya ubushyuhe, kandi ikwirakwira mu biribwa bidafite isukari kandi bifite karori nke.
Iby'ubwiza n'ubuvuzi bw'umuntu ku giti cye
HPMC ishobora gukoreshwa mu bikoresho byo kwita ku ruhu no mu isabune nk'ikintu gikomeza ubushyuhe.
HPC ikwiriye cyane mu bikoresho byo kwita ku musatsi, imiti igabanya ubushyuhe n'ibicuruzwa byo kwita ku maso bitewe nuko ishonga neza mu mazi kandi ikagira amavuta meza.
Ibikoresho by'ubwubatsi
HPMC ni igice cy'ingenzi cy'imyambaro y'ubwubatsi, mortiers, na putty powder, bigira uruhare mu gutuma amazi akomera, kubika amazi no kongera gufatana.
HPC ntikoreshwa cyane mu nganda z'ubwubatsi, ariko ishobora gukoreshwa mu mavuta n'ibindi bikoresho bishongesha amazi.
5. Kurengera no kubungabunga ibidukikije
HPMC na HPC byombi bikomoka kuri selulosi karemano kandi bifite ubushobozi bwo kubora no kwiyubakira. Muri rusange HPMC ifatwa nk'aho idahumanya kandi idatera ububabare, mu gihe HPC nayo ikoreshwa cyane mu biribwa no mu buvuzi, yujuje ibisabwa mu mutekano bya FDA (Ikigo gishinzwe ibiribwa n'imiti muri Amerika) n'andi mahame mpuzamahanga.
6. Ibyifuzo byo guhitamo
Niba hakenewe ubukana bwinshi n'ubushobozi bwo gukora filime, HPMC irakwiriye, nko gusiga ibinini, gusiga ibikoresho by'ubwubatsi n'ibindi bikorwa.
Niba hakenewe uburyo bwo gushonga neza no guhuza neza ibinyabutabire, HPC irakwiriye, nk'imiti inyobwa, ibikoresho bishyushye byo gushonga, nibindi.
HPMCnaHPCni ibintu by'ingenzi bikomoka kuri selulosi, bitandukanye mu miterere ya chimique, gushonga, n'ahantu bikoreshwa. HPMC ikwiriye cyane gukoreshwa mu gushonga cyane, gushyuha nka gusiga ibinini n'ibikoresho by'ubwubatsi, mu gihe HPC ikwiriye cyane gukoreshwa mu guteka mu kanwa, mu kwisiga no mu kunoza ibiryo bitewe nuko ishonga neza mu mazi kandi idafite ubukana bwinshi. Dukurikije ibyo ukeneye, guhitamo ibikoresho bikwiye bishobora kunoza imikorere n'ubudahangarwa bw'ibicuruzwa.
