Cellulose ether HE usoro, ya bụ, hydroxyethyl cellulose, bụ ọcha na-acha ọcha ntụ ntụ. Enwere ike ịgbaze ya na mmiri ọkụ na mmiri oyi, ma ọ dịghị mfe igbari na organic solvents. Ngwaahịa usoro nke cellulose ether HE nke Jinshi nwere njigide mmiri siri ike, imepụta ihe nkiri, nguzogide nnu na mmetụta na-abawanye. Ọ nwekwara ezigbo ndakọrịta agba na ọ bụ ezigbo mgbakwunye na ngwa latex.

Hydroxyethyl cellulose HEC bụ ihe a na-ejikarị eme ihe na mkpuchi ma nwee uru ndị a:

(1) Ọdịiche siri ike Hydroxyethyl cellulose HEC bụ polymer na-abụghị ionic mmiri soluble nke a pụrụ iji mee ihe n'ọtụtụ pH (2-12). Enwere ike ịgwakọta ya na ihe ndị dị na mkpuchi n'ozuzu (dịka pigmenti, ihe mgbakwunye, salts soluble na electrolytes) na-enweghị ihe ndị na-adịghị mma. nke

(2) Ihe owuwu dị mma. Ihe mkpuchi a na-agbanye na hydroxyethyl cellulose HEC nwere pseudoplasticity, ya mere enwere ike itinye ya na brushing, spraying, roller cover na ụzọ ndị ọzọ na-ewu ụlọ. Uru, ọkwa ọkwa dịkwa mma. nke

(3) Enweghị mmetụta ọjọọ na ihe nkiri mkpuchi. N'ihi njirimara na-adịghị ahụkebe nke mmiri na-adịghị ahụkebe nke ngwọta mmiri HEC, ọ dịghị mfe ịfụ ụfụ n'oge a na-ewu na mmepụta ihe, ọ dịghịkwa ọchịchọ ịmepụta oghere mgbawa ugwu na pinholes. nke

(4) Ezi mmepe agba. Hydroxyethyl cellulose HEC nwere ọmarịcha miscibility na ọtụtụ ndị na-ekekọta na agba, nke mere na agba a kwadebere nwere ezigbo nkwụsi ike na agba.

(5) Ezi nkwụsi ike nchekwa. N'oge nchekwa nke agba, ọ nwere ike ịnọgide na-enwe nkwusioru na dispersibility nke pigmenti, na-enweghị nsogbu nke sere n'elu na blooming. Enwere obere oyi akwa n'elu agba. Mgbe okpomọkụ nchekwa na-agbanwe, viscosity ya na-anọgide otu. kwụsie ike karị.
