Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose(HEC)
CAS: 9004-62-0
Hydroxyethyl Cellulose(HEC) ke nonionic water-soluble cellulose ether, e sebelisoang e le thickener, colloid e sireletsang, moemeli oa ho boloka metsi le rheology modifier ka mekhoa e fapaneng e kang lipente tse thehiloeng metsing, thepa ea mohaho, lik'hemik'hale tsa tšimo ea oli le lihlahisoa tsa tlhokomelo ea botho.
HEC e entsoe ka ho hlahisa lihlopha tsa hydroxyethyl (-CH₂CH₂OH) ka har'a ketane ea cellulose polymer ka karabelo ea etherification. Phetoho ena e ntlafatsa ho qhibiliha ha eona ha metsi, matla a ho tenya, le ho lumellana le libopeho tse fapaneng.

Melemo ea Bohlokoa:
1. Poloko e Ntle ea Metsi: E thusa ho thibela ho omisoa pele ho nako lihlahisoa tse entsoeng ka samente le litlolo.
2. E Tsitsitse Ho Fetisisa pH Range: E lula e sebetsa maemong a asiti, a sa nke lehlakore, le a alkaline.
3. Non-Ionic and Compatible: E sebetsa hantle ka lik'hemik'hale tse fapaneng, ho kenyelletsa le letsoai, li-surfactants, le li-polymer tse ling.
4. E Ntlafatsa Ts'ebetso ea Sehlahisoa: E ntlafatsa botenya, ho khomarela, ho etsa lifilimi le thepa ea emulsification.
5. Li Setsoalle le Tikoloho 'me Li ka Senyeha: E tsoa ho selulose, HEC ha e chefo ebile e ka senyeha.
6.E Ntlafatsa Rheology le Thepa ea Phallo: E lumella viscosity e laoloang, ho thibela ho rotha, ho theoha, le ho arohana ha mekhahlelo.
