Ethyl Hydroxyethyl Cellulose (EHEC) na agba mkpuchi akwụkwọ

Ethyl hydroxyethyl cellulose (EHEC) bụ polymer soluble mmiri nke a na-ejikarị eme ihe na ụlọ ọrụ akwụkwọ dị ka ihe njide na enyemaka nkwụsị. A na-etinyekarị ya na pulp n'oge a na-ede akwụkwọ iji meziwanye njide ihe ndochi na eriri na iji mụbaa ọnụ ọgụgụ mmiri mmiri. A pụkwara iji EHEC mee ihe na agba mkpuchi akwụkwọ iji meziwanye arụmọrụ nke mkpuchi ma kwalite àgwà nke ngwaahịa ikpeazụ.

Agba mkpuchi akwụkwọ bụ usoro a na-etinye n'ime akwụkwọ iji meziwanye ihe ndị dị n'elu ya, dị ka nchapụta, ire ụtọ, gloss, na mbipụta. Agba mkpuchi na-enwekarị ngwakọta nke pigmenti, ihe ndị na-ekekọta ihe, ihe ndochi, na ihe mgbakwunye ndị a chụsasịrị n'ime mmiri ka ha wee mepụta slurry. A na-etinye slurry ahụ na akwụkwọ ahụ site na iji ụzọ mkpuchi dị iche iche, dị ka mkpuchi agụba, mkpuchi mkpanaka, ma ọ bụ mkpuchi mma ikuku.

A na-ejikarị EHEC eme ihe dị ka onye na-ekekọta na agba mkpuchi akwụkwọ iji mee ka adhesion ha na akwụkwọ ahụ dịkwuo elu ma mee ka ike ha dịkwuo elu na ogologo oge. A na-ejikwa ya dị ka ihe na-eme ka ọkpụkpụ na-eme ka viscosity na nkwụsi ike nke agba mkpuchi, nke nwere ike inye aka belata mmebi nke ntụpọ dị ka streaks, pinholes, na mkpuchi mkpuchi. EHEC nwekwara ike imeziwanye gloss na ire ụtọ nke mpempe akwụkwọ a na-ekpuchi, nke nwere ike ime ka mbipụta na ihe ngosi nke ngwaahịa ikpeazụ.

Otu n'ime uru ndị dị mkpa nke iji EHEC na agba mkpuchi akwụkwọ bụ ikike ịmepụta ihe nkiri siri ike, nke na-agbanwe agbanwe nke nwere ike iguzogide nrụgide nke usoro ntinye akwụkwọ na ihe siri ike nke njikwa, mbupu, na nchekwa. EHEC nwekwara ike imeziwanye mmiri na-eguzogide mmiri na ink absorption Njirimara nke mkpuchi, nke nwere ike imeziwanye àgwà na ịdịte aka nke ihe oyiyi a na-ebipụta.

Uru ọzọ nke iji EHEC na agba mkpuchi akwụkwọ bụ ndakọrịta ya na ihe ndị ọzọ a na-ejikarị eme ihe n'ụdị mkpuchi. Enwere ike itinye EHEC n'ụzọ dị mfe na nhazi agba mkpuchi na-enweghị mmetụta na-adịghị mma na arụmọrụ nke ihe ndị ọzọ dị ka pigmenti, fillers, na dispersants. A pụkwara iji EHEC na-ejikọta ya na ihe ndị ọzọ, dị ka styrene-butadiene latex (SBL) na polyvinyl alcohol (PVOH), iji mee ka arụmọrụ nke mkpuchi dịkwuo elu.

ethyl hydroxyethyl cellulose (EHEC) bụ polymer vasatail nwere ike iji na agba mkpuchi akwụkwọ iji meziwanye arụmọrụ ha ma welie àgwà nke ngwaahịa ikpeazụ. EHEC nwere ike imeziwanye adhesion, ike, na ịdịte aka nke mkpuchi ahụ, yana gloss, ire ụtọ, na mbipụta nke mpempe akwụkwọ mkpuchi. Nkwekọrịta ya na ihe ndị ọzọ a na-ejikarị eme ihe n'ụdị mkpuchi na-eme ka ọ bụrụ nhọrọ mara mma maka ndị na-emepụta akwụkwọ na-achọ imeziwanye arụmọrụ nke agba mkpuchi ha.
