Hydroxyyeryl selile na Ethyl selile

1. Ibitekerezo by'ibanze

HydroxyAythyl Cellulose (HEC): HydroxyAythyl Cellulose (HEC) ni ikigo cya polymer polymer, ubusanzwe cyabonetse no guhuza selile. Itsinda rya Hydroxyyeryl (-ch2ch2oh) ryatangijwe muri molekile, zikaguha amazi meza, kubyimba, kurimbuka no gukora. HEC ikoreshwa cyane mu mirima myinshi nk'ibikota, kwisiga, ibikoresho, ibiryo, imiti, imiti.

Ethyl selile (EC): Ethyl selile (EC) nacyo ni igicapo cya Ether cyakomokaga kuri selile kamere. Bitandukanye na Hec, Ethyl (-C2H5) Itsinda ryatangijwe muri molekile ya EC aho kuba hydroxyyerthyl itsinda. Ifite ibibazo bikennye kandi mubisanzwe bishonje mubintu bya kama ariko bidahunze mumazi. EC ikunze gukoreshwa munganda nka faruceuticals, amatara no kumenza, kandi afite imibanire, ihamye ndetse na firime.

2. Itandukaniro mumiterere yimiti no kukecururizwa

Imiterere yimiti:
Imiterere ya Mole ya HEC yashinzwe muguhindura molekile ya selile binyuze kuri HydroxyAythyl (Ch2ch2oh) Amatsinda asimburwa. Iyi miterere ituma hec hydrophilic kandi irashobora gushonga neza mumazi.
Muri Molekile ya EC, Ethyl (C2H5) gusimbuza amatsinda ya hydroxyl muri selile, ituma molekile zayo handdrophobic kandi ikundwa nabi mumazi, mubisanzwe bishonga mubi.
Kudashoboka:

HEC irashonje byoroshye mumazi, cyane cyane mumazi ashyushye, kandi kukeshanwa kwayo bifitanye isano nuburemere bwa molekile nurwego rwa hydroxyetylation. Kubera amazi yacyo, HEC ikunze gukoreshwa mubihe byo kwishyurwa namazi bisabwa, nkibisohoka, abahozeho, nibindi.
EC ifite ibibazo bikennye mumazi, ariko ifite ubwitonzi bwiza mubintu bya kama nka alcon licvents na ketone. Kubwibyo, EC ikoreshwa kenshi mubidukikije kama nkawe cyangwa firime yabanje.

3. Imirima isaba

Gusaba Hec:
Ipara: Hec ikoreshwa nkuwihishe hamwe namagambo ahindura amazi ashingiye kumazi, ashobora guteza imbere amazi, guhagarika no kurwanya imvura.
Amavuta: Mu nganda zihirika, HEC ikunze gukoreshwa mubicuruzwa nkibintu byo kwisiga, shampoos, hamwe na cream yuruhu nkuwibi, na moustrizer.
Ubuvuzi: HEC ikoreshwa no kugenzurwa-igenzurwa no kurekura ibiyobyabwenge nkuwabyibushye nuwagize umukozi wa dolling kugirango afashe kurekura ibiyobyabwenge buhoro.
Kubaka: Mu nganda zubwubatsi, hec ikoreshwa nkuwijimye wa sima cyangwa minisiteri kugirango atezimbere imikorere yubwubatsi, nko gutanga umwanya ufunguye kandi utezimbere.

Gusaba EC:
Farumasiti: Amokol selile yakoreshejwe mu rwego rw'umuriro, cyane cyane mu myiteguro y'ibiyobyabwenge, nk'abatwara ibiyobyabwenge, atwara film, n'ibindi.
Amavuta no kumenyera: Mu nganda zifata, EC ikunze gukoreshwa nkuwabyimbye na firime byahoze. Irashobora kongera ubunini bwo gupfuka no kuzamura irwanya ikirere.
Ibiryo: EC ikoreshwa no mugihugu cyibiribwa, cyane cyane nkumubyimba na stilizer, kandi ikoreshwa mubiryo nka jelly na bombo.
Kwisiga: EC ikoreshwa mugukora kwisiga kugirango yongere vinosiya kandi ituze ya emulision, kandi irashobora kandi gukoreshwa nkicyitonderwa kuruhu.

4. Kugereranya imikorere

Kubyimba:
HEC na EC bafite ingaruka nziza cyane, ariko hec yerekana ko ikomeye mumazi, ikwiriye cyane kuri sisitemu. EC yerekana ingaruka nziza yijimye cyane cyane mubiti byamagana bitewe na hydrophobicity.

Kudacogora no gushikama:
Hec ifite amazi meza no gutuza cyane, bityo birakoreshwa cyane muri sisitemu. EC ifite ibibazo bikennye kandi ikoreshwa cyane mubintu byiza cyangwa sisitemu ya anhys.

Rheologiya:
Ibintu byimyuka yibisubizo bya hec ibisubizo biratandukanye cyane muburyo butandukanye, mubisanzwe byerekana imyitwarire isanzwe itari nshya muri Newtonian. EC mubisanzwe ifite imiterere ugereranije, cyane cyane mubiti bya kama.

Hydroxyyeryl selile (hec) na Ecthll selile ni ibikomoka kuri selile, buri kimwe gifite imitungo idasanzwe yumubiri na shimi idasanzwe hamwe nibisabwa byinshi. Amazi meza ya hec no kubyimba akoreshwa cyane muri sisitemu ishingiye ku mazi, nk'ibikota, kwisiga, kwisiga, n'imiti. EC ikunze gukoreshwa muri sisitemu ya solvent, nka farumage Guhitamo byombi bigomba kugenwa bishingiye kubisabwa byihariye bya porogaramu nuburyo bworoshye.
