Ninde uruta, CMC cyangwa HPMC?

CMC (sodium carboxymethyl selulose) na HPMC (hydroxypropyl methyl selulose) ni bibiri bikomoka kuri selile, bikoreshwa cyane mubikorwa bitandukanye. Kubijyanye nimwe muribyiza, biterwa nibisabwa byihariye nibisabwa.

1. Imiterere yimiti
CMC ni anionic water-soluble polymer compound yabonetse mukuvura selile naturel hamwe na sodium chloroacetate mubihe bya alkaline. Amatsinda ya Carboxymethyl yinjizwa mumurongo wa molekile yayo, bigatuma igira amazi meza kandi ikabyimba.

HPMC ni ether ya ionic selulose ether yabonetse mugukora selile hamwe na methyl chloride na okiside ya propylene. Amatsinda ya methoxy na hydroxypropoxy mumiterere ya molekulire ya HPMC itanga kubyimbye neza, gutuza no gufata amazi, ndetse nuburyo bwiza bwa gel.

2. Imirima yo gusaba
Inganda zibiribwa: CMC ikoreshwa mubiribwa nkibibyimbye, stabilisateur, guhagarika agent na emulisiferi, nibindi, kandi bikunze kuboneka muri yogurt, ice cream, jelly, ibinyobwa nibicuruzwa bitetse. Irashobora kongera ubwiza bwibiryo kandi ikongerera igihe cyo kubaho. Nubwo HPMC ikoreshwa no mu nganda y'ibiribwa, ikoreshwa cyane cyane nk'inyongera ya fibre y'ibiryo, cyane cyane mu bicuruzwa bimwe na bimwe bidafite gluten.

Inganda zikoreshwa mu bya farumasi: HPMC ikoreshwa cyane mu nganda zimiti, cyane cyane mu gutwikira ibinini, imiti igenzurwa-ikorwa na capsule. Imiterere yayo itari ionic hamwe na biocompatibilité nziza itanga ibyiza byihariye muri sisitemu yo gutanga ibiyobyabwenge. CMC ikoreshwa kandi mu nganda zimiti, ariko cyane nkibyimbye kandi bifata imiti.

Inganda zubaka no gutwikira: HPMC ikoreshwa cyane mubikoresho byubaka, cyane cyane muri minisiteri yumye, gypsumu, nifu ya putty, kubera kubika amazi meza, kubyimba no kurwanya kunyerera. CMC ifite kandi porogaramu zimwe na zimwe mu nganda zitwikiriye, ariko zikoreshwa cyane nko kubyimbye zishingiye ku mazi.

Amavuta yo kwisiga no kwita ku muntu ku giti cye: HPMC ikoreshwa kenshi mu kwisiga, cyane cyane mu mavuta yo kwisiga, amavuta, shampo hamwe n’amenyo y’amenyo, nkibyimbye, stabilisateur ya emulsiyo na moisturizer. CMC nayo ikoreshwa mubisabwa bisa, ariko ingaruka zayo zo kuba nziza ntabwo ari nziza nka HPMC.

3. Ibiranga imikorere
Amazi meza: CMC irashobora gushonga neza mumazi akonje kandi ashyushye, mugihe HPMC ishobora gushonga byoroshye mumazi akonje, ariko ntigashonga mumazi ashyushye kandi ifite ubushyuhe bwumuriro. Kubwibyo, HPMC irakwiriye cyane kubicuruzwa bisaba imiterere yubushyuhe bwumuriro mubisabwa bimwe na bimwe, nkibinini bigenzurwa-bisohora mubuvuzi.

Igenzura rya Viscosity: CMC ifite ubukonje buke ugereranije kandi byoroshye kugenzura, mugihe HPMC ifite intera nini kandi irahuza cyane. HPMC irashobora gutanga ubukonje bwinshi kandi igakomeza guhagarara neza mubushyuhe butandukanye, ibyo bigatuma irushaho kuba byiza mubisabwa bisaba kugenzura neza neza.

Ihamye: HPMC ifite imiti ihamye kuruta CMC. Yerekana ituze ryiza mubidukikije bya acide cyangwa alkaline, mugihe CMC ishobora gutesha agaciro acide ikomeye cyangwa base base.

4. Igiciro nigiciro
Muri rusange, CMC irahendutse kandi ikwiranye ninganda nini zikoreshwa mu nganda, mu gihe HPMC ihenze cyane kubera ibikorwa byayo bigoye kandi bihenze cyane. CMC irashobora kuba nziza mugihe ibintu byinshi bisabwa kandi ikiguzi cyoroshye. Nyamara, mubice bimwe na bimwe bisabwa gukora cyane, nk'ubuvuzi hamwe no kwisiga byo mu rwego rwo hejuru, HPMC iracyakoreshwa cyane kubera ibyiza byayo bidasanzwe nubwo igiciro cyayo kiri hejuru.

5. Kurengera ibidukikije n'umutekano
CMC na HPMC zombi zifite ibinyabuzima byiza no kurengera ibidukikije, kandi bigira ingaruka nke kubidukikije mugihe cyo gukoresha. Byombi bifatwa nkibiryo byizewe nibiyobyabwenge, kandi birashobora gukoreshwa neza mubicuruzwa bitandukanye nyuma yo kugenzurwa no gutanga ibyemezo.

CMC na HPMC bafite ibyiza byabo nibibi, kandi ntibishoboka kuvuga gusa icyiza. Kubisabwa bisaba ibiciro bidahenze, umusaruro munini, nkinganda rusange yibiribwa nibikenewe byoroheje, CMC ni amahitamo meza. Mubice bifite imikorere isabwa cyane, nka sisitemu yo kurekura imiti igenzurwa, ibikoresho byo mu rwego rwo hejuru byubaka ibikoresho byo kwisiga bigezweho, HPMC irashobora kuba nziza kubera imikorere yayo myiza. Kubwibyo, guhitamo ibikomoka kuri selile biterwa nibisabwa byihariye bisabwa, ibisabwa nibikorwa hamwe nibitekerezo.
