Methylcellulose nuruvange rwinshi kandi rwinshi rufite porogaramu mubikorwa bitandukanye kubera imiterere yihariye. Iyi polysaccharide ikomoka kuri selile irazwi cyane kubushobozi bwayo bwo gukina inshingano zitandukanye mubice bitandukanye.
Imiterere yimiti ya methylcellulose:
Methylcellulose ikomatanyirizwa muri etherification ya selile, polymer karemano iboneka murukuta rwibimera. Cellulose igizwe na glucose ibice bihujwe na β-1,4-glycosidic. Gahunda ya etherification ikubiyemo gusimbuza hydroxyl mumatsinda ya selile hamwe na methyl. Ihindurwa ryimiti ritanga methylcellulose yavuyemo imiterere yihariye, bigatuma ishonga mumazi mubihe bimwe.
Urwego rwo gusimbuza (DS) rugereranya umubare mpuzandengo wamatsinda ya hydroxyl yasimbujwe nitsinda rya methyl kuri buri gice cya glucose mumurongo wa selile, bigira ingaruka kumyuka, ububobere nubushobozi bwa methylcellulose. Mugihe DS yiyongera, gukomera mumazi no guhinduranya muri rusange kwiyongera.
Ibiranga methylcellulose:
Amazi meza: Imwe mumpamvu nyamukuru zituma methylcellulose ikoreshwa cyane nukubura amazi. Irerekana imyitwarire idasanzwe mubisubizo byamazi - gukora gel isobanutse kandi igaragara neza iyo ishonga mumazi akonje. Uyu mutungo ni ingenzi mubisabwa kuva mu nganda y'ibiribwa kugeza kuri farumasi.
Ubushyuhe bwa Thermal: Methylcellulose ikora inzira ihindagurika bitewe n'ubushyuhe. Iyo ishyushye, igisubizo cyamazi ya methylcellulose ikora gel, hanyuma imaze gukonja, gel igaruka kumuti. Uyu mutungo ufite agaciro cyane mugutegura geles hamwe na sisitemu yo gutanga ibiyobyabwenge.
Ubushobozi bwo gukora firime: Methylcellulose ikora firime isobanutse kandi yoroheje ikwiranye ninganda zikoreshwa mubiribwa nka coatings, adhesives na firime ziribwa. Ibikoresho byo gukora firime bigira ingaruka kubintu nko kwibanda, ubushyuhe no kuba hari izindi nyongeramusaruro.
Imiterere ya Rheologiya: Methylcellulose yerekana imyitwarire yo kogosha, bivuze ko ububobere bwayo bugabanuka mugihe cyo guhangayika. Uyu mutungo ufite akamaro mubisabwa nkibishushanyo aho bisabwa byoroshye kandi ibikoresho bikenera kugarura ububobere nyuma yo kubisaba.
Biocompatibilité: Biocompatibilité ya methylcellulose ningirakamaro mubikorwa bya farumasi na biomedical medicine. Mubisanzwe bifatwa nkumutekano kugirango ukoreshwe mumiti ya farumasi kuko ntabwo ari uburozi kandi budatera imbaraga. Ibi byatumye yinjizwa mubicuruzwa bitandukanye bya farumasi, harimo ibisubizo byamaso hamwe na sisitemu yo gutanga imiti igenzurwa.
Gukoresha methylcellulose:
inganda z'ibiribwa:
Umubyimba: Methylcellulose ikoreshwa nkibintu byongera mubiribwa nkibisosi, imyambarire hamwe nisupu kubera ubushobozi bwayo bwo gutanga ibishishwa bidahinduye uburyohe cyangwa isura yibicuruzwa byanyuma.
Gusimbuza ibinure: Mubiribwa birimo ibinure bike cyangwa bidafite amavuta, methylcellulose irashobora kwigana imiterere hamwe numunwa wamavuta, bikongerera uburambe.
ibiyobyabwenge:
Guhuza ibinini bya tableti: Methylcellulose ikoreshwa nkumuhuza mu nganda zimiti kugirango utezimbere guhuza ibinini bya tablette kandi urebe ko ibinini bikomeza kuba byiza mugihe cyo gukora no kubikoresha.
Ophthalmic Solutions: Gukorera mu mucyo wa methylcellulose mubisubizo byamazi bituma bikwiranye nubuvuzi bwamaso nkibitonyanga byamaso hamwe nigisubizo cya lens ibisubizo.
Inganda zubaka:
Inyongera ya sima na Mortar: Methylcellulose yongewe kumasima ya sima na minisiteri kugirango bitezimbere imikorere, gufata amazi no kuyifata. Irinda gukama vuba, itanga uburyo bwiza bwo gukira no gukira.
Irangi hamwe n'ibifuniko:
Thickeners and Stabilisers: Methylcellulose ikoreshwa nkibyimbye hamwe na stabilisateur mu marangi ashingiye kumazi no gutwikira kugirango bifashe kugera kubyo bifuza no gukumira pigment gutura.
Inganda z’imyenda:
Sizing agent: Mugutunganya imyenda, methylcellulose ikoreshwa nkigikoresho kinini kugirango yongere ubworoherane nimbaraga za fibre. Itanga igifuniko kirinda mugihe cyo kuboha kandi ikarinda kumeneka kwa fibre.
Ibicuruzwa byita ku muntu:
Amavuta yo kwisiga: Methylcellulose yinjizwa mu mavuta yo kwisiga nka cream n'amavuta yo kwisiga bitewe na emulsiyo ihagaze neza kandi ikabyimba.
Inganda za peteroli na gaze:
Amazi yo gucukura: Methylcellulose ikoreshwa mugucukura amazi mu nganda za peteroli na gaze kugirango igabanye ubukonje n’igihombo cy’amazi kugirango ibikorwa byogucukura neza.
Impapuro no gupakira:
Kwiyongeraho gutwikira: Methylcellulose ikoreshwa nk'inyongeramusaruro ku mpapuro n'ibikoresho byo gupakira kugira ngo bisohore neza, bitunganijwe neza kandi birwanya amazi.
Umuyoboro:
Stabilisateur muri Detergents: Methylcellulose irashobora kongerwaho mumazi yo kwisiga nka stabilisateur kugirango irinde gutandukana kwicyiciro no kunoza ituze muri rusange.
Gukoresha ibinyabuzima:
Sisitemu yo Gutanga Ibiyobyabwenge: Methylcellulose ikoreshwa mugutezimbere uburyo bwo gutanga imiti igenzurwa-kurekurwa, kandi imiterere ya thermogelling ituma irekurwa rihoraho ryibiyobyabwenge mugihe runaka.
Icapiro rya 3D:
Ibikoresho byo gushyigikira: Mu icapiro rya 3D, methylcellulose irashobora gukoreshwa nkibikoresho byunganira, bishobora gukurwaho byoroshye nyuma yo gucapwa kubera amazi yabyo.
Methylcellulose nikintu cyiza kandi gihindagurika hamwe nibisabwa mubikorwa bitandukanye. Ihuza ryayo ridasanzwe ryokubura amazi, geli yumuriro, ubushobozi bwo gukora firime hamwe na biocompatibilité ituma iba ingirakamaro mubiribwa, imiti, ibikoresho byubaka, amarangi, imyenda, ibicuruzwa byita kumuntu nibindi byinshi. Mugihe ikoranabuhanga ninganda bikomeje gutera imbere, uburyo bwinshi bwa methylcellulose butuma bufite akamaro kandi bugakomeza gukoreshwa muguhuza ibikenerwa ninganda zitandukanye.
