Hydroxyethyl Cellulose ni iki?

Hydroxyethyl selulose ni umweru cyangwa umucyo wa fibrous yumuhondo cyangwa ifu ikomeye, idafite uburozi, uburyohe, kandi byoroshye gushonga mumazi. Ntishobora gukemuka muri rusange ibishishwa kama. Ifite imiterere yo kubyimba, guhagarika, guhuza, kwigana, gutatanya, no kugumana ubushuhe. Ibisubizo bifite ubunini butandukanye burashobora gutegurwa. Ifite umunyu mwiza udasanzwe muri electrolytite. Hydroxyethyl selulose ni umweru cyangwa urumuri rwumuhondo rutagira impumuro nziza, uburyohe, kandi byoroshye gutemba. Irashobora gushonga mumazi akonje kandi ashyushye, kandi muri rusange ntashonga mumashanyarazi menshi. Ubukonje buhinduka gake mugihe pH agaciro kari murwego rwa 2-12, ariko ububobere bugabanuka kurenza iyi ntera.

Gusaba

1. Hydroxyethyl selulose (HEC) ni ether idafite ionic soluble selulose ether ifite umubyimba mwiza, guhagarikwa, gutatanya, emulisation, gufatira hamwe, gukora firime, kurinda ubushuhe hamwe nuburinzi bwa colloid. Bitewe nimiterere yihariye yumubiri nubumashini, HEC ikoreshwa cyane mubice byinshi, harimo ariko ntibigarukira gusa mu gukuramo amavuta, gutwikira, kubaka, ibiryo bya farumasi, imyenda, gukora impapuro na polymer polymerisation.
2. Mu rwego rwa farumasi, usibye kuba umubyimba kandi urinda, hydroxyethyl selulose inagira ingaruka zo gutobora, guhumeka, kurwanya gusaza, gusukura uruhu, no gukuraho melanine. Irakwiriye gukora ibitonyanga by'amaso, gutera amazuru, ibisubizo byo mu kanwa, n'ibindi. Birashobora kongera ubukana bwibiyobyabwenge, bikongerera umuvuduko wimiti yibiyobyabwenge mumubiri, kandi bikongerera umutekano wibiyobyabwenge kugirango wirinde kwangirika kwibiyobyabwenge na okiside.
3. Mu nganda zo kwisiga, HEC ikoreshwa cyane mugukora shampoo, kondereti, cream, amavuta yo kwisiga nibindi bicuruzwa. Irashobora guhindura ubwiza nuburyo bwo kwisiga kugirango byoroshe kubishyira no kubyakira. Muri icyo gihe, igira kandi ingaruka nziza, irashobora gufunga ubuhehere, kandi ikarinda gukama uruhu no guturika.
4. Byongeye kandi, hydroxyethyl selulose ikoreshwa cyane cyane mubyimbye, ibara ryamabara kandi ikingira ibicuruzwa mu nganda zibiribwa, bishobora kongera ubwiza nubwiza bwibiryo kandi bikazamura uburyohe nubwiza bwibiryo. Irashobora kandi gukoreshwa nka emulisiferi na stabilisateur kugirango irinde ibiribwa n’imvura.
5. Kubijyanye na acide na alkaline ya hydroxyethyl selulose, kubera ko ari mubyiciro bya selile ya ionic selile, ntabwo ari acide cyangwa alkaline. Imiti yimiti ni (C2H6O2) n, hamwe no gukemuka neza, gutuza no kubyimba, kandi bigira uruhare runini mubikorwa bitandukanye byo gukoresha.
