Carboxyymethyl selile?

Sodium Carboxymethyl Cellulose (CMC) ni ikigo gisanzwe kandi gikoreshwa cyane hamwe nibisabwa byinshi munganda zitandukanye.

Intangiriro kuri sodium carboxymethyl selile ya selile (cmc)
Sodiyumu Carboxymethyl Cellulose, akenshi ameze nabi nka CMC, ni ukomoka kuri selile, kimwe mu busitani bwinshi bwo ku isi. Cellulose, igizwe no gusubiramo ibice bya glucose bihujwe na β (1 → 4) ubumwe bwa glycosidic, buboneka cyane cyane kurukuta rwa selile yibimera, bitanga inkunga yububiko. Irashoborarwaho, Biodegraductable, nibidafite uburozi, bikabigira ibikoresho bibisa kubisabwa byinganda.

Imiterere n'imiterere
CMC irimo guhinduranya selile binyuze mu buryo bunyuranye, aho hydroxyl amatsinda ya selile yasimbuwe nitsinda rya Carboxymethyl (-ch2-cooh). Uku gusimburwa rutanga ubwitonzi bwamazi no kunoza ibintu byimiterere kuri selile, bigatuma bikwiranye nuburyo butandukanye.

Urwego rwo gusimbuza (DS) bivuga impuzandengo y'imibare ya Carboxymethyls kuri Glucose ishami rya selile kandi igira ingaruka kumitungo ya CMC. Indangagaciro Zisumba indangagaciro ziterwa no kongera amazi menshi.

CMC mubisanzwe iraboneka nkifu yera kuri ifu yera, ifite ubunini butandukanye bitewe nibisabwa. Nibyiza, bidafite uburyohe, kandi bidafite uburozi, bikaba byiza koresha mubiryo nibicuruzwa bitwara imiti. CMC irahamye muburyo butandukanye bwa PH kandi byerekana imiterere nziza ya firime.

Uburyo bwo gutanga umusaruro
Umusaruro wa CMC urimo intambwe nyinshi:
Gutegura Cekwille: Ubugari buringaniye biturutse ku mwobo, ipamba, cyangwa izindi fibre ziterwa. Ubugari burimburwa kandi bimenetse muri fibre nto kugirango byongere gukora.

Imyifatire ya Guhuza: Fibre ya feri yasukuye ifatwa na sodium hydroxide (naoh) kugirango ukoreshe amatsinda ya hydroxyl. Nyuma yaho, acide monochloroacetic (cyangwa sodium ya sodium) yongewe kumurongo uvanze kugirango utangire amatsinda ya carboxymethyl kuri selile.

Kutabogama no gukaraba: nyuma yo gutandukana, ibicuruzwa bivamo, ibicuruzwa bivanwaho na aside kugirango ihindure muburyo bwa sodium. CMC noneho yogejwe kugirango ikureho umwanda nibicuruzwa.

Kuma no gusya: CMC isukuye yumye kugirango ikureho ubushuhe burenze kandi igaboraga igera ku bunini bwifuzwa.

Ikoresha no gusaba
Sodium carboxymethyl selile selile isanga ikoreshwa mu nganda zitandukanye:
Inganda zibiribwa: CMC ikoreshwa cyane nkuwabyimbye, stabilizer, nubushuhe bwabujijwe mubiribwa nkibikoresho byamagari, ibicuruzwa bitetse, n'amaso, hamwe no kwambara. Itezimbere imiterere, irinda Syneresisi, kandi yongerera umunwa mubiryo.

Ibikoresho bya faruceuticace: Mu nganda za farumasi, CMC ikoreshwa nka Bunder muri Tablet foinetions, ahindura visosity mu guhagarikwa, hamwe na malubric mubisubizo bya Ophthalmic. Iremeza ibiyobyabwenge kimwe no gufungurwa.

Ibicuruzwa byita kugiti cyawe: CMC yinjijwe mubicuruzwa byitaweho nka Shampoo, hamwe no ku ruhu rw'uruhu nk'abakozi bijimye, Emalifier, na Umukozi wa Filime.

Inganda zimpapuro: Mumpapuro, CMC yongewe kuri lup for plep kugirango itezimbere imbaraga, imiterere yubuso, no kugumana inyongeramusaruro na DYES. Irashobora kandi kwimura imiyoboro ikagabanya umukungugu mugihe cyo gutanga impapuro.

Inganda zimyenda: CMC ikoreshwa muburyo bwo gucapa no gusiga irangi nkumubyimba na binder kuri pides. Yorohereza uburyo bumwe bwo kubitsa no kuzamura uburakari bwacapwe.

Inganda za peteroli na gaze: CMC ikoresha mumazi yo gucukura nka virusi ya viscosiier na fluid kugabanya amazi. Ifasha gukomeza guhangayikishwa na borehole, guhagarika ibinini, no kugenzura imyuka yamazi mugihe cyo gucukura.

Inganda zubwubatsi: Mu bikoresho byubwubatsi nka minisiteri, ibisumo, hamwe nibicuruzwa bya Gypsum, CMC ikora nkabakozi bangamiwe n'amazi, kunoza imikorere no kumera.

Ibikoresho byogurika no gusukura: CMC yongewe mubihingwa, isuku, no kumesa nkibicuruzwa byijimye kandi bihambiriye. Itezimbere viscolity yamashanyarazi kandi itezimbere imikorere yabo muri rusange.

Ibitekerezo by'umutekano
Sodiyumu Carboxymethyl selile yatunganijwe muri rusange ifatwa nkumutekano (Gras) kugirango ikoreshwe mu biribwa n'ibikoresho by'ibiyobyabwenge n'ibiyobyabwenge by'Amerika n'ibiyobyabwenge (EFSA). Ariko, ni ngombwa kugirango wubahirize ibipimo byihariye byubukungu n'imikoreshereze yo gukumira ingaruka mbi.

Mugihe CMC ifatwa nkibidafite uburozi, guhumeka cyane cyangwa kwinjirira ibice byumukungugu birashobora gutera uburakari nubutumwa bwubuhumekero. Ibikoresho byiza hamwe nibikoresho byo kurinda umuntu (PPE) bigomba gukoreshwa mugihe cyo gukora no gutunganya.

Ingaruka y'ibidukikije
CMC ikomoka mu buryo bushoboka, ahanini byangirika bishingiye ku bihingwa, bigatuma bizima. Irimo guterwa no gutesha agaciro kashe, amaherezo isenyuka muri dioxyde ya karuboni, amazi, na biomass.

Ariko, inzira yo gukora ya CMC ikubiyemo imyitwarire mibi nintambwe zingenzi, zishobora gutanga umusanzu mubidukikije nkimyanzuro y'ibidukikije nk'ibyuka bihumanya ingufu, ibyo bikaha bya Greenhouse, no mu gisekuru cyamazi. Imbaraga zo kunoza inzira z'umusaruro, kongera imbaraga zingufu, kandi kugabanya imyanda birashobora kugabanya ibibazo bidukikije.

Sodium Carboxymethyl Cellulose (CMC) ni urugo rutandukanye hamwe nibisabwa bitandukanye mubiryo, farumasi, imiti, impapuro, impapuro, nizindi zinama. Umutungo wacyo wihariye nka polymer-gukosora amazi atuma nta makosa akora muburyo butandukanye, aho bikora nkumubyimba, stabilizer, binder, hamwe na vindomer, na vicosity.
