Niki hydroxyeyithyl selile

Hydroxyyeryll Cellulose: Incamake
HydroxyAythyl Cellulose (HEC) ni polymer itari ionic, gukosora amazi yakomokaga muri selile, umuhanga mu kamere nini cyane ku isi. Kubera imitungo yacyo itandukanye, HEC ikoreshwa cyane mu nganda zitandukanye, harimo imiti, kwisiga, gushushanya, no kubaka.

Synthesis ya hydroxyyeryl selile
Umusaruro wa Hec urimo gutandukanya selile. Iyi nzira itangirana na selile ifatwa na sodium hydroxide kugirango itange selile ya alkali. Ethylene Oxide noneho yongerwaho kuri uru ruvange, bikaviramo gushinga hydroxyyethyl selile. Imyitwarire irashobora guhagararirwa nkibi bikurikira:

Cellulose-Ona + NCH2CH2O → Cellulose-Och2ch2oh

Urwego rwo gusimbuza (DS) no gusimbuza umuryango (MS) ni ibipimo by'ingenzi mu kugena imitungo ya HEC. DS ivuga impuzandengo y'imibare ya hydroxyl kuri molekile ya selile yasimbuwe, mugihe ms yerekana umubare wikigereranyo cya Moles okiside ya Etylene kuri glucose ishami rya selile. Ibi bipimo bigira ingaruka mubikesha, vicosity, nibindi bintu bikora EC.

HEC ifite ibintu byinshi bitandukanye:

Gukemurwa: Hec irashonje mumazi ashyushye kandi akonje, bituma bihurira cyane kubisabwa bitandukanye. Irashobora gukora neza, ibisubizo byimbitse bihamye hejuru ya ph.

Viscosity: viscozetity yibisubizo bya hec biterwa nuburemere bwayo no kwibanda. HEC irashobora kubyara intera nini ya virusi, bigatuma ari ingirakamaro mubisabwa bisaba ibiranga byihariye.

Ubushobozi bwo gushinga film: Hec irashobora gukora firime zitoroshye, ziboneye. Uyu mutungo ni ingirakamaro cyane mubyoherejwe no kwisiga.

Umukozi wijuriye: Hec ni umukozi mwiza wijimye, utanga inyungu zifuzwa kandi ituje mubitera.

Guhagarara: Hec ni imiti ihamye kandi irwanya gutesha agaciro n'umucyo, ubushyuhe, na mikorobe, byongera kuramba muburyo butandukanye.

Porogaramu ya HydroxyAythyl Cellulose
Bitewe numutungo wihariye, HEC isanga porogaramu mumirima myinshi:

Farumasiti: Mu nganda za farumasi, hec ikoreshwa nka bunder, firime-yahozeho, nuwabyimbye mubinini namavuta. Ifasha mu kurekurwa ibiyobyabwenge kandi itezimbere imiterere kandi ituze.

Kwisiga: HEC ikunze gukoreshwa mubicuruzwa byitaweho nka Shampoos, amavuta, na cream. Itanga viso yifuzwa, yongerera ibyiyumvo nibicuruzwa, kandi igahatira emuli.

Irangi n'amakota: mu nganda zipaki, Hec ikora nk'igituba, Stabilizer, na bakozi bashinzwe amazi. Itezimbere imitungo yo gusaba irangi, irinda kugabanuka, no kureba no gushiraho firime.

Kubaka: HEC ikoreshwa mubikoresho byubwubatsi nka sima na plaster. Irongera ibikorwa, kugumana amazi, no kumeneka, kuzamura imikorere no kuramba byibi bikoresho.

Inganda zibiribwa: Nubwo bidasanzwe, HEC irashobora gukoreshwa nkuwabyimbye kandi stilizer mubicuruzwa bimwe na bimwe byibiribwa, byemeza imiterere yoroshye kandi ihungabanye.

Inganda zimyenda: Hec ikoreshwa nkumukozi wambaye mu nganda, atanga imbaraga no gutuza kwidoda mugihe cyo kuboha.

Umutekano n'ibidukikije
Muri rusange ahabwa amaso afatwa neza gukoreshwa muburyo butandukanye, cyane cyane muri farumasi no kwisiga, aho byageragejwe cyane kuburozi no kurakara. Ntabwo ari uburozi, butabangamiye, kandi hypollergenic, bigatuma bikwiranye no gukoresha ibicuruzwa bikoreshwa kuruhu cyangwa kwangirika.

Biturutse ku bidukikije, HEC ni bizima kandi ikomoka ku mutungo ushoborarwaho (selile). Umusaruro wacyo no gukoresha bifitanye isano ningaruka zibidukikije. Ariko, kimwe n'imiti yose, gutunganya neza birakenewe kugirango dugabanye ingaruka zishobora guteza ibidukikije.

Hydroxyyeryl selile ni polymer itandukanye kandi ifite agaciro ifite porogaramu nini mu nganda zitandukanye. Umutungo wacyo wihariye, nko kwishyurwa n'amazi, kugenzura urukwavu, ubushobozi bwo gushinga filime, no gutuza, bigatuma bitarushajwe mu bicuruzwa biva mu bikoresho by'ubwubatsi. Synthesis ya Hec kuva selile igereranya gukoresha neza umutungo kamere, atanga umusanzu mubikorwa birambye. Hamwe numwirondoro ukomeye wumutekano nigihe kidasanzwe cyibidukikije, HEC ikomeje kuba ikintu cyingenzi mubice bitandukanye byubucuruzi no mu nganda.
