Methylcellulose ether (MC), cyangwa methylcellulose, ni polymer idafite amazi-soluble polymer ifite imiterere ya molekile igizwe ahanini no gusimbuza amatsinda ya hydroxyl muri selile hamwe nitsinda rya methyl. Ihinduka ryemerera methylcellulose ethers kwerekana ibyiza byihariye mubikorwa bitandukanye.

Methyl selulose ether ifite imbaraga zidasanzwe mumazi, kandi igisubizo cyacyo kigaragaza ingaruka nziza cyane mubyerekezo byinshi. Uyu mutungo utuma ukoreshwa cyane mubice bisaba kubyimbye neza, nkibifuniko, ibifatika, amarangi hamwe nibifatika. Muri ubu buryo, methylcellulose ether irashobora gutanga ububobere buhamye kuri sisitemu kandi ikagaragaza pseudoplastique munsi yimpu zogosha, ni ukuvuga ko ubwiza bwigisubizo bugabanuka ku gipimo cyinshi cyogosha, ibyo bikaba bifasha mubikorwa byo kubaka no gutwikira.
2. Ubushyuhe bwumuriro
Methyl selulose ether ifite imiterere ya thermogelling, ni ukuvuga ko ikora gel iyo ishyushye igasubira muburyo bwayo nyuma yo gukonja. Uyu mutungo ni ingenzi cyane mugutunganya ibiryo. Kurugero, mugihe cyo gutunganya ibiryo no guteka, methylcellulose ethers irashobora kuba nkubushyuhe butajegajega hamwe nubushakashatsi bwa gelling, kunoza imiterere nuburyohe bwibiryo mugihe bikomeza imiterere nubushuhe.
3. Imikorere yo gufata amazi
Methyl selulose ether ifite ubushobozi bwiza bwo gufata amazi kandi irashobora kugumana ubushuhe mubihe bitandukanye. Ibi biranga ingenzi cyane mubikoresho byo kubaka. Kurugero, iyo bikoreshejwe mumasima ya sima nibicuruzwa bya gypsumu, birashobora gukumira neza gutakaza amazi menshi, bityo bikazamura imikorere yimikorere no kubumba ibintu. Byongeye kandi, nk'ibikoresho bitwikiriye imbuto mu buhinzi, methylcellulose ether irashobora kandi gufasha kubungabunga ubutaka no kuzamura imbuto.
4. Ibintu byiza cyane byo gukora firime
Imiterere ya firime ya methylcellulose ethers ituma iba nziza muburyo bwo gutwikira hejuru. Kurugero, mugutwikira ibinini bya farumasi, methylcellulose ethers irashobora gukora firime imwe, idafite firime itanga uburyo bwiza bwo kurinda no kugenzura ibiyobyabwenge. Mu nganda zo gutwikisha impapuro no gutwikira, ikoreshwa kandi nk'umukozi ukora firime kugirango atezimbere ubuso burambye kandi burambye bwibicuruzwa.
5. Guhagarika no gutatanya ibintu
Methyl selulose ether ifite ibyiza byo guhagarika no gukwirakwiza ibintu, bikabasha gukwirakwiza ibice bikomeye muburyo bumwe. Uyu mutungo ni ingenzi cyane muburyo bwo gutwika no gusiga amarangi, aho birinda pigment gutuza kandi bigateza imbere irangi hamwe nuburinganire. Mu kwisiga, irashobora kwemeza gukwirakwiza ibice hamwe nibigize, kunoza imiterere no gukoresha ingaruka zibicuruzwa.
6. Kutagira imiti n’umutekano
Methyl selulose ether ihagaze neza muburyo bwa chimique kandi ntabwo ikora nibindi bikoresho bigize imiti, ikarinda umutekano wabyo mubikorwa bitandukanye. Ibi bituma ikoreshwa cyane mubiribwa, imiti nubuvuzi bwo kwisiga. Nkinyongeramusaruro, methylcellulose ether ifatwa nkumutekano, ntabwo irimo uburozi ubwo aribwo bwose, kandi ntizigogorwa kandi ngo yinjizwe mumubiri. Nkimiti yimiti, irashobora gutanga imiti ihamye, kugenzura igipimo cyo kurekura, no kunoza uburyohe no kumira.
7. Biocompatibilité
Methyl selulose ether ifite biocompatibilité nziza kandi irakwiriye gukoreshwa mumiti yimiti nibicuruzwa byawe bwite. Nkimiti yimiti, irashobora guhuza neza nibintu bikora bitagize ingaruka kumikorere yibiyobyabwenge, mugihe bitezimbere uburyohe no kurekura imikorere yibiyobyabwenge. Mu bicuruzwa by'amaso, methylcellulose ethers nayo ikoreshwa nk'amavuta n'amavuta yo kunoza ibicuruzwa no gukora neza.
8. Kubungabunga ibidukikije
Methyl selulose ether ikomoka kuri selile naturel, irashobora kwangirika kandi ntizatera umwanda ibidukikije. Kubwibyo, mu rwego rw’inganda zigezweho z’imiti n’iterambere rirambye, methylcellulose ether yazamuwe cyane kandi ikoreshwa kubera ibidukikije byangiza ibidukikije.
9. Guhagarara no kuramba
Methylcellulose ethers yerekana ituze ryiza hejuru yubushyuhe bwagutse na pH. Irashobora kugumana imiterere yayo mugihe cya acide cyangwa alkaline kandi ntabwo byoroshye ingaruka kubidukikije. Ibi bituma bikwiranye nuburyo butandukanye bwo gusaba kandi bugakomeza imikorere n'imikorere mugihe kirekire.
10. Guhinduranya no gukoresha mugari
Methyl selulose ethers ifite imikorere itandukanye kandi irashobora guhindurwa no guhindurwa nkuko bikenewe, nko guhindura ubushobozi bwabyo, ubwiza bwimiterere nibikorwa bikora uhindura urwego rwo gusimbuza nuburemere bwa molekile. Kubwibyo, methylcellulose ether ifite amahirwe menshi yo gukoreshwa mubwubatsi, ibiryo, ubuvuzi, kwisiga, ubuhinzi nizindi nzego, bihuza ibikenerwa bitandukanye ninganda zitandukanye.
Methylcellulose ether yishingikiriza kumazi meza yayo meza, kubyimbye, gufata ubushyuhe, kubika amazi, gukora firime, guhagarika no gutatanya, kutagira imiti, umutekano, ibinyabuzima, guhuza ibidukikije, kubungabunga ibidukikije, gutuza no Kuramba bigira uruhare runini mubikorwa bya kijyambere no mubuzima bwa buri munsi. Ubwinshi bwarwo hamwe nuburyo butandukanye bwibikorwa bituma biba ibikoresho byingirakamaro mu nganda nyinshi.
