Hydroxyethyl cellulose (HEC)
Hydroxyethyl cellulose(HEC)
CAS: 9004-62-0
Hydroxyethyl cellulose(HEC) bụ nonionic mmiri soluble cellulose ether, eji dị ka thickener, echebe colloid, mmiri njigide gị n'ụlọnga na rheology modifier na dị iche iche ngwa dị ka mmiri dabeere agba, ụlọ ihe, mmanụ ubi chemicals na onye nlekọta ngwaahịa.Due ka ya ahụkebe Njirimara, dị ka elu viscosity, solubility na mmiri ọkụ na oyi na-atụ, na chemical kwụsie ike, HEC bụ ihe dị oké mkpa na ụlọ ọrụ mmepụta ihe.
A na-ahazi HEC site na iwebata otu hydroxyethyl (-CH₂CH₂OH) n'ime agbụ polymer cellulose site na mmeghachi omume etherification. Mgbanwe a na-eme ka mmiri dị nro ya dịkwuo mma, ike ịgbasa, na ndakọrịta na usoro dị iche iche.
