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

Agwa:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) bụ ntụ ntụ ọcha ma ọ bụ odo odo nke na-enweghị isi, enweghị isi, ma na-asọ asọ ngwa ngwa. A na-agbaze na mmiri oyi na mmiri ọkụ, mana ọ naghị agbazekarị na ọtụtụ ihe mgbaze organic. Uru pH na-agbanwe ntakịrị na oke nke 2-12, mana viscosity na-ebelata karịa oke a.

Uru:Hydroxyethyl Cellulose (HEC CAS:9004-62-0) bụ ihe na-eme ka ihe dị arọ nke a na-ejikarị eme ihe maka ink sitere na mmiri organic nke ether dabere na cellulose. Ọ bụ ihe na-anaghị agbaze mmiri nke nwere ike ime ka mmiri dị mma, oxygen, asịd, na enzymes nwere ike imebi, Cu2+ nwekwara ike ijikọ ya na mmiri n'okpuru ọnọdụ alkaline. Ọ na-adịgide adịgide n'oge okpomọkụ, ọ naghị apụta ka gel mgbe a na-ekpo ọkụ, ọ naghị apụta n'okpuru ọnọdụ acidic, ma nwee ezigbo ihe na-eme ka ihe nkiri dị mma. Enwere ike ime ka ihe ngwọta mmiri ya bụrụ ihe nkiri doro anya, nke enwere ike ịmepụta site na ọrụ nke alkaline cellulose na Chemicalbook ethylene oxide, ma nwee ihe onwunwe nke thickening, emulsification, adhesion, suspension, film-forming, retaining mmiri, na nchedo colloid. Ọrụ nke ndị na-eme ka ihe dị arọ na ink dabere na mmiri bụ ime ka ha dị arọ. Ịtinye ihe ndị dị arọ na ink na-eme ka viscosity ya dịkwuo elu, nke nwere ike ime ka nkwụsi ike anụ ahụ na kemịkalụ nke ink dịkwuo mma; N'ihi mmụba nke viscosity, enwere ike ijikwa rheology nke ink n'oge mbipụta; Agba na ihe e ji eme ihe n'ime ink adịghị mfe ịpụta, nke na-eme ka ink e ji mmiri mee ka ebe nchekwa ya dịkwuo mma.

Ụzọ Mmepụta：Alkali cellulose bụ polima eke nke nwere otu hydroxyl atọ na mgbanaka eriri ọ bụla. Otu hydroxyl kachasị arụ ọrụ na-emeghachi omume iji mepụta hydroxyethyl cellulose. Mikpuo linte owu a na-anaghị amị amị ma ọ bụ pulp a nụchara anụcha na alkali mmiri 30%, wee wepụ ya maka ịpị mgbe ọkara awa gachara. Pịa ruo mgbe mmiri alkaline ruru 1:2.8, wee gwerie ya. A na-etinye alkali cellulose a gwepịara egwepịa n'ime reactor, mechie ya, kpoo ya, ma jupụta ya na nitrogen. A na-eji mmiri ethylene oxide eme ihe ugboro ugboro ma jupụta ya na nitrogen iji dochie ikuku niile dị na reactor. Pịa mmiri ethylene oxide a gwepịara egwepịa, tinye mmiri oyi n'ime jaket reactor, ma chịkwaa okpomọkụ mmeghachi omume ruo ihe dị ka 25 ℃ maka awa 2 iji nweta ngwaahịa hydroxyethyl cellulose dị nro. A na-asa ngwaahịa ahụ na mmanya, tinye ya na acetic acid ruo pH 4-6, ma jikọta ya na glyoxal maka ịka nká. Mgbe ahụ, saa ya na mmiri, centrifuge, kpoo ya mmiri, kpọọ nkụ, ma gwerie ya iji nweta hydroxyethyl cellulose.
