Methyl selileulose ether?

Intangiriro kuri erendikire ya selile:
Cellulose nimwe mubintu byinshi byamavuta ku isi, biboneka mu rukuta rw'Akagari z'ibimera. Ni polysaccharide igizwe no gusubiramo ibice bya glucose bihujwe hamwe na β (1 → 4) injyana ya glycosic. Abashiraho selile ni bo bakomoka kuri selile, aho umwe cyangwa benshi mu matsinda ya hydroxyl (-Oh) asimburwa n'amatsinda ya Ether (-or). Ibisimbuza bihindura umubiri nu miti ya selile, bigatuma bikwiranye nibisanzwe byinganda.

Methyl selile: ibisobanuro n'imiterere:
Methyl selile ni umuhanga wa selile wakomotse kuri selile mu gusimbuza amatsinda ya hydroxyl hamwe na methyl (-ch3) amatsinda ya ether. Uku gusimbuza ibisubizo muri polymer hamwe no kwikebagura mumazi hamwe nibindi bikoresho bya porlan ugereranije na selile kavukire. Urwego rwo gusimbuza (DS) bivuga impuzandengo y'imibare ya hydroxyl yasimbuwe n'amatsinda ya Methyl Ether kuri Glucose ishami rya selile kandi agena imitungo ya Methyl selile.

Imiterere yimiti ya methyl selile irashobora gutandukana bitewe nurwego rwo gusimburwa no gukwirakwiza amatsinda ya methyl ether kuruhande rwa selile. Mubisanzwe, methyl molekile molekile ni umurongo wa polymers ufite iminyururu ihindagurika, ukabemerera gushiraho ibisubizo hamwe nibintu bidasanzwe byimitungo.

Inganda Inganda:
Ubusanzwe Methyl yakozwe binyuze muburyo bworoshye bwa selile hamwe na methyl chloride cyangwa methyl sutates ya alkaline. Igisubizo kirimo gusimbuza amatsinda ya hydroxyl hamwe nitsinda rya methyl ether, bikavamo gushiraho methyl selile. Urwego rwo gusimburwa rushobora kugenzurwa no guhindura uko ibintu bimeze nkubushyuhe, igihe cyimyitwarire, hamwe na seliki ya selile kumukozi wa methin.

Nyuma ya synthesis, ibicuruzwa bigenda byitabaza intambwe zo gukuraho umwanda no kubicuruzwa. Ibi birashobora kuba bikubiyemo gukaraba, kurwara, no kumisha inzira yo kubona ifu ya Cellloulose ya Methoulose cyangwa granules.

Umutungo wa Methyl selile:
Methyl selile igaragaza imitungo myinshi idasanzwe ituma ikwiye kubisabwa muburyo butandukanye:

Amazi yonyine: Methyl selile arashonga mumazi akonje, akora ibisubizo bisobanutse, viscous. Kudakemurwa birashobora kongera imbaraga mu kongera urwego rwo gusimburwa.

Ubushyuhe bwumuriro: Methyl selile birahagaze neza, kubungabunga imitungo yayo hejuru yubushyuhe bwinshi. Uyu mutungo utuma ukwiranye na porogaramu isaba kurwanya ubushyuhe.

Gushiraho filime: Methyl selile irashobora gukora firime zoroshye, zibonerana iyo ziva mu gisubizo. Izi firime zifite inzitizi nziza hanyuma ushake porogaramu mubirori no gupakira ibikoresho.

Kwinginga no guhagarara: Methyl selile ikora nk'umukozi wijimye mu bisubizo bitangaje, byongera uruspo kandi mugutezimbere imiterere. Irashobora kandi gukora urusenda rwumugati hejuru yibitekerezo, bikaba bifite akamaro mubiryo nibikorwa bya farumasi.

Igikorwa cyo hejuru: Methyl selile exrahye ibintu bikora hejuru, bishobora gukoreshwa mu kumenyekana no guteza imbere sisitemu ya Colloidal.

Gusaba Methyl selile:
Methyl selile isabwa gusaba cyane mu nganda zinyuranye kubera imitungo yacyo itandukanye:

Inganda zibiribwa: Mu nganda zibiribwa, methyl selile ikoreshwa nkumukozi wijimye, stabilizer, na emalifie mubicuruzwa nkibisomero, imyambarire, hamwe nibikoresho. Itezimbere imiterere, yongerera umunwa, kandi itanga ituze ryahagaritswe.

Farumasiti: Methyl selile irakoreshwa cyane muri farumasi nka farumasi nkurugero, rutandukanya, kandi rurambye-kurekura umukozi mubinini na capsules. Irashobora kandi gukoreshwa mubiterano byingenzi nka gels, amavuta, n'amavuta yo kubyimba no mucoadies.

Kubaka: Methyl selile ikoreshwa mubikoresho byubwubatsi nka minisiteri, plaster, na tile ifata nkumukozi wijimye kandi uhagarikwa namazi. Itezimbere imikorere, kumena, no gukumira guterera uruvange buto.

Kwisiga: Muri kwisiga hamwe nibicuruzwa byita kugiti cyawe, Methyl selile bikoreshwa mubikorwa nka cream, amavuta, shampos, ninyo yoroshye cyane nkumubyimba, na Agenthing. Itanga igenzura rya vino, yongerera imiterere, kandi itezimbere imikorere yibicuruzwa.

Porogaramu yinganda: Methyl selile ikoreshwa muburyo butandukanye bwinganda nko gucapa imyenda, amatara yimpapuro, no gufata ibikoresho byo kwinuba, guhuza, hamwe numutungo wa firime.

Ingaruka y'ibidukikije:
Mugihe Methyl selile muri rusange ifatwa nkumutekano kugirango ukoreshe ibiryo, imiti, nibindi bikorwa, ingaruka zibidukikije zigomba gusuzumwa neza. Abashiraho selile ni boodegradagemekwa bakomoka kubutunzi bushoboka, bigatuma bangiza ibidukikije ugereranije na synthique polymeti. Ariko, uburyo bwo gukora bushobora kuba bukubiyemo gukoresha imiti n'imbaraga, bigira uruhare mu guhugira ibidukikije hamwe n'ubwikorikori bwa gare.

Imbaraga zirimo gushyirwaho hashyizweho ingufu z'umusaruro urambye ukoresheje inzira ya greenner synthesis, amasoko ashobora kongerwa, no gutunganya ibicuruzwa. Byongeye kandi, kujugunya methyl ibikomoka kuri selile bikubiyemo bigomba gucungwa neza kugirango ugabanye umwanda wibidukikije.

Methyl selile ni ubudahangawe nimiterere yihariye ikora agaciro mu nganda zitandukanye. Amazi yonyine, ituze ryumuriro, kubyimba, hamwe numutungo wa film utunganijwe neza, harimo ibiryo, imiti, kwisiga, no kubaka. Mugihe Methyl selile itanga inyungu nyinshi, ingaruka zibidukikije zigomba gucungwa neza binyuze mubikorwa birambye bitanga umusaruro nuburyo bwo kurohama. Muri rusange, Methyl selile ugira uruhare runini mu ikoranabuhanga rigezweho n'ubuzima bwa buri munsi, bigira uruhare mu iterambere ry'ibicuruzwa bishya n'ibisubizo.
