Kugirango ugereranye CMC (Carboxymethylcellsells) na HPMC (HYDROXYPropylmethylcelcellcellSelcellsells), dukeneye kumva imitungo yabo, gusaba, ibyiza, ibibi, no gukoresha imanza. Ibikomoka kuri Celeulose byombi bikoreshwa cyane mu nganda zitandukanye, harimo imiti, ibiryo, kwisiga no kubaka. Buri kimwe gifite imitungo idasanzwe ituma ikwiye intego zitandukanye. Reka dukore uburemere bwuzuye kugirango turebe imwe nziza mubihe bitandukanye.
1. ibisobanuro n'imiterere:
CMC (CarboxymethylcellsellSlcellse): CMC ni ugukemura amazi yatewe n'amazi byakozwe na acide ya selile na chloroacetic. Irimo amatsinda ya carboxymethyy (-ch2-cooh) ihuba kuri amwe mumatsinda ya hydroxyl ya monomer ya glucosranose igira umugongo wa selile.
HPMC (HydroxyPropyl Methylcellsellse): HPMC nayo ikomoka kumazi yakozwe nukuvura selile hamwe na proploride ya proparlene na methyl chloride. Irimo HydroxyPropyl na Methoxy Amatsinda yometse kuri selile.
2. Kudakemurwa:
CMC: Yokewe cyane mumazi, gukora igisubizo gisobanutse, gikemu. Iyerekana imyitwarire ya pseudopplastique ya pseudoplastique, bivuze ko viscometity yayo igabanuka munsi yimihangayiko.
HPMC: Nanone gushonga mumazi, gukora igisubizo cya virusike kuruta CMC. Irerekana kandi imyitwarire ya pseudoplastique.
3.Imitungo ya 3.imiterere:
CMC: Erekana imyitwarire yoroheje, bivuze ko ubukuru bwayo bugabanuka hamwe no kongera umubare munini. Uyu mutungo utuma ukwiye gusaba aho bisabwa ushikamye ariko igisubizo gikeneye gutemba munsi ya shear, nkamashusho, ibikoresho hamwe na farumasi.
HPMC: Erekana imyitwarire isa na CMC, ariko viscosity yayo muri rusange iri hejuru mubintu bike. Ifite imiterere-yimiterere myiza ya firime, bigatuma habaho gusaba nkibisohoka, kumenyekana no kugenzura-kurekura imiti.
4. Guhagarara:
CMC: Mubisanzwe bihamye hejuru ya PH nubushyuhe. Irashobora kwihanganira urwego ruciriritse rwa electrolytes.
HPMC: Bihamye kuruta CMC mubihe bya aside, ariko birashobora guhura na hydrolysise muburyo bwa alkaline. Nurutondeye kandi kumavuta ya macoaki, bishobora gutera i pelation cyangwa imvura.
5. Gusaba:
CMC: Byakoreshejwe cyane nka Thickener, Stabilizer hamwe namazi yo kugumana amazi mubiryo (nka ice cream, isosi), gusiga amatara) no kwisiga) Inganda) Inganda.
HPMC: Bikunze gukoreshwa mubikoresho byubwubatsi (urugero, sima, plaster, minisiteri), kwitegura imiti (urugero, ibitonyanga byamaso, ibitonyanga byamaso).
6. Uburozi n'umutekano:
CMC: Mubisanzwe bizwi nkumutekano (Gras) ninzego zishinzwe kugenzura mugihe cyakoreshejwe mumipaka yagenwe mubiryo nibisabwa na farumasi. Ni Biodegraduatable hamwe nabatari uburozi.
HPMC: Kandi yabonaga umutekano kubikoreshwa mubipimo byasabwe. Nibinyabuzima kandi bikoreshwa cyane mumibare ya farumasi nkumukozi ugenzurwa na tablet binder.
7. Ikiguzi kandi kiboneka:
CMC: Mubisanzwe birenze urugero kuruta HPMC. Biraboneka byoroshye kubaranze batandukanye kwisi.
HPMC: Birahenze gato kubera ibikorwa byayo kandi rimwe na rimwe bitangwa kubatanga isoko.
8. Ingaruka y'ibidukikije:
CMC: Biodegradable, ikomoka kubikoresho bishobora kongerwa (selile). Bifatwa nk'inshuti.
HPMC: Nanone Biodegradable ikomoka kuri Celeulose, kandi nanone urugwiro.
CMC na HPMC bafite imitungo idasanzwe ibagira uruhare runini munganda nyinshi. Guhitamo hagati yabo biterwa nibisabwa bisabwa nkibisubizo, viscosiya, umutekano no gutekereza kubitekerezo. Muri rusange, CMC irashobora kuguhitamo kubera ikiguzi cyo hasi, igituba cyagutse, kandi kigomba gukoreshwa ibiryo no kwisiga. HPMC, kurundi ruhande, irashobora gutoneshwa nisubukuru yo hejuru, ibintu byiza bya firime bigize film, hamwe nibisabwa muri farumasi hamwe nibikoresho byubwubatsi. Ubwanyuma, guhitamo bigomba kuba bishingiye kubitekerezo byuzuye nkibi bintu no guhuza hamwe no gukoresha.
