HEC ku bicuruzwa byihariye byo mu rwego rwo kwisiga

HydroxyethylcelluloseHECni polymeri idashonga mu mazi idashobora gushonga mu mazi ishongera mu mazi ashyushye n'akonje. Hydroxyethylcellulose series HEC ifite ubwoko bwinshi bw'ubushyuhe, kandi ibisubizo by'amazi byose ni amazi atari ay'i Newtonian.

Hydroxyethyl cellulose ni ikintu cy'ingenzi mu bicuruzwa bya shimi bya buri munsi. Ntabwo ishobora kongera ubukana bw'amavuta cyangwa amavuta yo kwisiga, ahubwo inanoza uburyo ikwirakwira ry'amazi n'ifuro rihoraho.

akarusho:
1. Ifite amazi meza cyane.
2. Ifite ubwumvikane busesuye kandi bwuzuye.
3. Imiterere myiza cyane yo gukora filime.
4. Ifite imikorere ihendutse cyane.
5.Ifite ubushobozi bwo gusimbuza neza kugira ngo ikomeze kurwanya ubwivumbure igihe kirekire.

Igipimo cya polimeri:
Hari amatsinda atatu ya hydroxyl kuri buri gice cya anhydroglucose muri cellulose, ivurwa na alkali mu gisubizo cya sodium hydroxide y'amazi kugira ngo ibone umunyu wa sodium, hanyuma igakora reaction ya etherification hamwe na ethylene oxide kugira ngo ikore hydroxyethyl cellulose ether. Mu gikorwa cyo gukora hydroxyethyl cellulose, ethylene oxide ishobora gusimbura amatsinda ya hydroxyl kuri cellulose, hanyuma igakora reaction ya polymerization y'uruhererekane hamwe n'amatsinda ya hydroxyl mu matsinda yasimbuwe.

Hydroxyethylcellulose ifite ubushobozi bwo guhumeka neza cyane. Umuti wayo w'amazi uraryoshye kandi uhuye, ufite ubushyuhe bwiza kandi ugororotse. Kubwibyo, amavuta yo kwisiga arimo hydroxyethyl cellulose agira ubuziranenge bwiza kandi yuzuye mu gacupa, kandi akwirakwira byoroshye ku musatsi no ku ruhu iyo akoreshejwe. Ikoreshwa cyane mu bikoresho byo kogosha, mu byo gukaraba umubiri, mu masabune y'amazi, mu byo kogosha no mu mafuru, mu bwoya bw'amenyo, mu binini birwanya ibyuya, mu nyamaswa (abana bato n'abantu bakuru), mu binini bisiga amavuta.

Uretse kugenzura amazi,selulose ya hydroxyethylifite ubushobozi bwiza bwo gukora firime. Iyi firime ikozwe neza ko izaba iri mu rwego rwo hejuru munsi ya 350x na 3500x mu indorerwamo, kandi izana uruhu rwiza iyo rushyizwe mu mavuta yo kwisiga.
