Hydroxyethyl Cellulose (HEC) bụ ngwakọta mmiri na-agbaze mmiri nke a na-ejikarị na agba latex. Ọ bụghị naanị na ọ na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ ngwaahịa, kamakwa na-eme ka ahụmịhe ngwa ahụ dịkwuo mma na àgwà nke ihe nkiri mkpuchi ikpeazụ.
Njirimara nke Hydroxyethyl Cellulose
Hydroxyethyl cellulose bụ nonionic cellulose ether nke sitere na cellulose eke sitere na mgbanwe etherification. Ọ nwere ezigbo ndim, suspending, dispersing na emulsifying Njirimara. Njirimara ndị a na-enyere HEC aka ịmepụta colloid siri ike na ngwọta mmiri nwere nnukwu viscosity na ezigbo rheological Njirimara. Na mgbakwunye, ihe ngwọta mmiri nke HEC nwere nghọta dị mma na ikike ijide mmiri nke ọma. Njirimara ndị a na-eme ka a na-eji ya eme ihe na agba latex.
