Carboxymethyl cellulose sodium maka mkpuchi akwụkwọ

Carboxymethyl cellulose sodium (CMC-Na) bụ polymer soluble mmiri nke a na-ejikarị eme ihe na ụlọ ọrụ akwụkwọ dịka ihe mkpuchi.CMC-Nasitere na cellulose, nke bụ polymer eke dị na mgbidi cell osisi. Mgbanwe kemịkalụ nke cellulose na otu carboxymethyl na-ebute polymer mmiri na-eme ka mmiri na-emepụta ihe na-emepụta ihe nkiri mara mma, na-eme ka ọ bụrụ nhọrọ dị mma maka ngwa mkpuchi akwụkwọ.

Ihe mkpuchi akwụkwọ bụ usoro nke itinye ihe mkpuchi dị mkpa nke ihe mkpuchi n'elu akwụkwọ iji meziwanye mbipụta ya, ọdịdị ya na arụmọrụ ya. Enwere ike kewaa ihe mkpuchi mkpuchi n'ime ụzọ abụọ: mkpuchi agba na mkpuchi na-abụghị nke agba. Ihe mkpuchi nwere agba nwere agba agba, ebe mkpuchi na-abụghị nke na-apụta ìhè ma ọ bụ na-apụta ìhè. A na-ejikarị CMC-Na eme ihe dị ka ihe nkedo na mkpuchi na-abụghị pigmenti n'ihi ihe ndị na-emepụta ihe nkiri na ike imeziwanye ihe ndị dị n'elu dị ka ire ụtọ, gloss, na ink nnabata.

Ojiji nke CMC-Na na mkpuchi akwụkwọ na-enye ọtụtụ uru, gụnyere mma mkpuchi mkpuchi, nkwalite mbipụta, na mma mmiri na-eguzogide. N'isiokwu a, anyị ga-enyocha uru ndị a n'ụzọ zuru ezu, yana ihe dị iche iche na-emetụta arụmọrụ CMC-Na na ngwa mkpuchi akwụkwọ.

Mkpuchi mkpuchi emelitere

Otu n'ime uru ndị dị mkpa nke iji CMC-Na na mkpuchi akwụkwọ bụ ikike ya iji melite nkpuchi mkpuchi. CMC-Na bụ polymer hydrophilic nke nwere ike imekọrịta ihe na hydrophilic elu nke eriri akwụkwọ, na-eme ka adhesion dị mma n'etiti mkpuchi na elu akwụkwọ. Otu carboxymethyl dị na CMC-Na na-enye nnukwu njupụta nke saịtị ebubo na-adịghị mma nke nwere ike ịmepụta njikọ ionic na otu ndị nwere ebubo nke ọma na eriri akwụkwọ, dị ka amine ma ọ bụ otu carboxylate.

Tụkwasị na nke ahụ, CMC-Na nwekwara ike ịmepụta njikọ hydrogen na ìgwè hydroxyl na cellulose fibers, na-eme ka adhesion dị n'etiti mkpuchi na elu akwụkwọ. Nke a na-eme ka adhesion dị mma na-eme ka oyi akwa mkpuchi dị otu ma na-ebelata ihe ize ndụ nke mkpuchi mkpuchi n'oge usoro nhazi na-esote dị ka calendering ma ọ bụ mbipụta.

Enwerekwa ike ibipụta

Uru ọzọ nke iji CMC-Na na mkpuchi akwụkwọ bụ ikike ya ịkwalite mbipụta. CMC-Na nwere ike imeziwanye ire akwụkwọ n'elu site n'imeju oghere na oghere dị n'etiti eriri akwụkwọ ahụ, na-eme ka elu ahụ dị n'otu na-enwekwa obere mmebi. Ịdị nro a emelitere nwere ike iduga nfefe ink dị mma, belata oriri ink, yana mma mbipụta.

Na mgbakwunye, CMC-Na nwekwara ike imeziwanye nnabata ink nke elu akwụkwọ ahụ site n'inye akwa mkpuchi edo edo karịa nke na-amịkọrọ ma gbasaa ink nke ọma. Nkwekọrịta ink a na-eme ka ọ dịkwuo mma nwere ike ịkpata onyonyo dị nkọ, saturation agba ka mma, yana mbelata ink ink.

Mgbochi mmiri emelitere

Mmiri na-eguzogide mmiri bụ ihe dị mkpa nke mkpuchi akwụkwọ, karịsịa maka ngwa ebe akwụkwọ ahụ nwere ike igosi mmiri ma ọ bụ iru mmiri. CMC-Na nwere ike melite nguzogide mmiri nke mkpuchi akwụkwọ site na ịmepụta ihe mgbochi mgbochi nke na-egbochi mmiri ịbanye n'ime mpempe akwụkwọ.

Ọdịdị hydrophilic nke CMC-Na na-enyekwa ya ohere ịmekọrịta ya na mkpụrụ ndụ mmiri, na-eme ka nguzogide mmiri dịkwuo mma site na njikọ hydrogen na ịmepụta netwọk polymer interpenetrating. Enwere ike ịchịkwa ogo nke nkwụsị mmiri site n'ịgbanwe ntinye uche na ogo nke nnọchi nke CMC-Na na nhazi mkpuchi.
