Cellulose Hydroxyethyl(HEC)
CAS:9004-62-0
Cellulose Hydroxyethyl(HEC) bụ cellulose ether nke na-agbaze na mmiri na-abụghị ionic, nke a na-eji dị ka ihe na-eme ka ihe sie ike, ihe nchebe colloid, ihe na-ejide mmiri na ihe na-agbanwe rheology n'ọtụtụ ọrụ dịka agba mmiri, ihe owuwu ụlọ, kemịkalụ ubi mmanụ na ngwaahịa nlekọta onwe onye. N'ihi ihe ndị pụrụ iche ya, dị ka oke viscosity, ịgbaze na mmiri ọkụ na oyi, na nkwụsi ike kemịkalụ, HEC bụ ihe dị mkpa na ọtụtụ ngwaahịa ụlọ ọrụ mmepụta ihe na ndị ahịa.
A na-emepụta HEC site n'itinye otu hydroxyethyl (-CH₂CH₂OH) n'ime agbụ polymer cellulose site na mmeghachi omume etherification. Mgbanwe a na-eme ka mmiri na-agbaze, ike ịka njọ, na ndakọrịta ya na usoro dị iche iche dịkwuo mma.
