Isi ihe ọmụma gbasara Hydroxyethyl Cellulose (HEC CAS: 9004-62-0)

agwa:Hydroxyethyl Cellulose (HEC CAS: 9004-62-0) bụ isi awọ na-acha ọcha ma ọ bụ na-acha odo odo, enweghị isi, na ntụ ntụ na-eru ngwa ngwa.Soluble na ma mmiri oyi na mmiri ọkụ, ma n'ozuzu adịghị soluble na ọtụtụ organic solvents.Uru pH na-agbanwe ntakịrị na nso nke 2-12, mana viscosity na-ebelata karịa oke a.

Uru:Hydroxyethyl Cellulose (HEC CAS: 9004-62-0) bụ thickener a na-ejikarị eme ihe maka cellulose ether dabeere organic mmiri dabeere inks.Ọ bụ mmiri nonionic compound na-soluble nke nwere ezigbo ike ịgbatị mmiri, oxygen, acids na enzymes nwere ike imebi ya, yana Cu2 + nwere ike ịfefe ya n'okpuru ọnọdụ alkaline.Ọ na-ekpo ọkụ na-ekpo ọkụ, ọ naghị apụta gel n'oge okpomọkụ, ọ naghị amịpụta n'okpuru ọnọdụ acidic, ma nwee ezigbo ihe na-emepụta ihe nkiri.Enwere ike ịme ihe ngwọta mmiri ya ka ọ bụrụ ihe nkiri transperent, nke nwere ike ịmepụta site na omume nke alkaline cellulose na Chemicalbook ethylene oxide, ma nwee ihe ndị na-emepụta ihe, emulsification, adhesion, nkwusioru, imepụta ihe nkiri, njigide mmiri, na nchebe colloid.Ọrụ nke ndị na-ekpu mmiri na ink dabeere na mmiri bụ ime ka ha sie ike.Ịgbakwunye thickeners na ink na-abawanye viscosity ya, nke nwere ike imeziwanye nkwụsi ike anụ ahụ na kemịkal nke ink;N'ihi mmụba nke viscosity, rheology nke ink nwere ike ịchịkwa n'oge mbipụta;Ụcha na ihe nkpuchi dị na ink adịghị mfe ịmalite, na-abawanye nkwụsi ike nchekwa nke ink dabeere na mmiri.

Usoro mmepụta: alkali cellulose bụ ihe okike nke nwere otu hydroxyl atọ na mgbanaka eriri eriri ọ bụla.Otu hydroxyl kacha arụ ọrụ na-emeghachi omume iji mepụta hydroxyethyl cellulose.Wunye akwa akwa akwa ma ọ bụ pulp a nụchara anụcha na 30% mmiri mmiri alkali, wee wepụ ya maka ịpị mgbe ọkara elekere gachara.Pịa ruo mgbe ọdịnaya mmiri alkaline ruru 1: 2.8, wee gwepịa ya.A na-etinye cellulose alkali ahụ e gwepịara egwepịa n'ime reactor, mechie ya, kpochapu ya, ma jupụta na nitrogen.Akwụkwọ kemịkalụ na-ekpochapụ ugboro ugboro wee jupụta na nitrogen iji dochie ikuku niile dị na reactor.Pịa na mmiri mmiri ethylene oxide emechiri emechi, nyefee mmiri jụrụ oyi n'ime jaket reactor, ma jikwaa ọnọdụ mmeghachi omume ihe dịka 25 ℃ maka 2h iji nweta ngwaahịa hydroxyethyl cellulose crude.A na-asacha ngwaahịa ahụ na mmanya na-aba n'anya, wepụ ya na acetic acid na pH 4-6, yana njikọ glycoxal maka ịka nká.Mgbe ahụ, jiri mmiri, centrifuge, kpoo mmiri, kpoo, ma gwerie iji nweta hydroxyethyl cellulose.
