HydroxyethylcelluloseHECni polymer-ionic water-soluble polymer ikemuka mumazi ashyushye nubukonje. Hydroxyethylcellulose ikurikirana HEC ifite ibintu byinshi byijimye, kandi ibisubizo byamazi byose ni amazi atari Newtonian.
Hydroxyethyl selulose ninyongera yingenzi mubicuruzwa bya chimique bya buri munsi. Ntishobora gusa kunoza ubwiza bwamavuta yo kwisiga cyangwa amavuta ya emulsiya, ahubwo irashobora no gukwirakwiza no gutuza ifuro.
akarusho:
1.Afite hydration nziza cyane.
2. Ifite ihame rikomeye kandi ryuzuye.
3. Umutungo mwiza wo gukora firime.
4. Ifite imikorere ihenze cyane.
5.Ifite urwego rwiza rwo gusimburwa kugirango harebwe igihe kirekire cyo kurwanya ibicuruzwa byangiza ibicuruzwa.
Impamyabumenyi ya Polymerisation:
Hariho amatsinda atatu ya hydroxyl kuri buri gice cya anhydroglucose muri selile, kivurwa na alkali mumuti wa sodium hydroxide yo mumazi kugirango ubone umunyu wa sodium ya selile, hanyuma uhitemo etherification hamwe na okiside ya Ethylene kugirango ubeho hydroxyethyl selulose ether. Muburyo bwo guhuza hydroxyethyl selulose, okiside ya Ethylene irashobora gusimbuza amatsinda ya hydroxyl kuri selile, hanyuma ikagira urunigi rwa polymerisiyonike hamwe nitsinda rya hydroxyl mumatsinda yasimbuwe.
Hydroxyethylcellulose ifite imiterere myiza ya hydration. Igisubizo cyacyo cyamazi kiroroshye kandi kimwe, gifite amazi meza kandi aringaniye. Kubwibyo, kwisiga birimo hydroxyethyl selulose bifite ihame ryiza kandi ryuzuye muri kontineri, kandi bigakwirakwira byoroshye kumisatsi nuruhu iyo bishyizwe. Ikoreshwa cyane muri kondereti, gukaraba umubiri, amasabune yamazi, kogosha geles nifuro, umuti wamenyo, antoderspirant deodorants, tissue (abana nabakuze), amavuta yo kwisiga.
Usibye kugenzura amazi,hydroxyethyl selileifite firime nziza cyane. Filime yakozwe yijejwe kuba imeze neza munsi ya 350x na 3500x yerekana indorerwamo, kandi izana uruhu rwiza rworoshye iyo rukoreshejwe kwisiga.
