Polyanionic Cellulose (PAC) na Sodium Carboxymethyl Cellulose (CMC)

Polyanionic cellulose (PAC) na sodium carboxymethyl cellulose (CMC) bụ ihe ndị sitere na cellulose nke a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ maka ihe ndị na-eme ka ha sie ike, na-eme ka ha sie ike, na ihe ndị na-eme ka ha dị nro. Ọ bụ ezie na ha nwere ụfọdụ myirịta, ha nwekwara ọdịiche dị iche iche n'ihe gbasara nhazi kemịkalụ, ihe onwunwe, na ojiji. Lee ntụnyere dị n'etiti PAC na CMC:

1. Nhazi Kemịkalụ:
   • PAC: Polyanionic cellulose bụ polima mmiri na-agbaze site na cellulose site na iwebata carboxymethyl na otu anionic ndị ọzọ n'ime ọkpụkpụ azụ cellulose. O nwere ọtụtụ otu carboxyl (-COO-) n'akụkụ yinye cellulose, na-eme ka ọ bụrụ anionic nke ukwuu.
   • CMC: Sodium carboxymethyl cellulose bụkwa polima mmiri na-agbaze site na cellulose, mana ọ na-agafe usoro carboxymethylation kpọmkwem, nke na-ebute nnọchi nke otu hydroxyl (-OH) na otu carboxymethyl (-CH2COONa). CMC na-enwekarị obere otu carboxyl ma e jiri ya tụnyere PAC.
2. Ọdịdị Ionic:
   • PAC: Polyanionic cellulose bụ ihe na-anaghị agbanwe agbanwe nke ukwuu n'ihi na e nwere ọtụtụ otu carboxyl n'akụkụ yinye cellulose. Ọ na-egosipụta ike mgbanwe ion siri ike ma a na-ejikarị ya eme ihe dị ka ihe na-achịkwa nzacha na ihe na-agbanwe rheology na mmiri mmiri na-egwupụta mmiri.
   • CMC: Sodium carboxymethyl cellulose bụkwa anionic, mana ogo anionicity ya dabere na ogo nnọchi (DS) nke otu carboxymethyl. A na-ejikarị CMC eme ihe dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka ihe sie ike, na ihe na-agbanwe viscosity n'ọtụtụ ngwa, gụnyere nri, ọgwụ, na ngwaahịa nlekọta onwe onye.
3. Viscosity na Rhology:
   • PAC: Polyanionic cellulose na-egosipụta oke viscosity na àgwà ịkpụ akpụ na mmiri, na-eme ka ọ dị irè dị ka ihe na-eme ka ihe dị arọ na ihe na-agbanwe rheology na mmiri mmiri na ngwa ụlọ ọrụ ndị ọzọ. PAC nwere ike iguzogide oke okpomọkụ na ọkwa nnu a na-ahụ na ọrụ ubi mmanụ.
   • CMC: Sodium carboxymethyl cellulose na-egosipụtakwa viscosity na rheology, mana viscosity ya na-adịkarị ala ma e jiri ya tụnyere PAC. CMC na-emepụta ngwọta kwụsiri ike na pseudoplastic, na-eme ka ọ dabara adaba maka ọtụtụ ojiji, gụnyere nri, ihe ịchọ mma, na ọgwụ.
4. Ngwa:
   • PAC: A na-ejikarị Polyanionic cellulose eme ihe n'ụlọ ọrụ mmanụ na gas dị ka ihe na-achịkwa nzacha, ihe na-agbanwe rheology, na ihe na-ebelata mfu mmiri n'ime mmiri ndị a na-egwupụta. A na-ejikwa ya eme ihe n'ụlọ ọrụ mmepụta ihe ndị ọzọ dịka ihe owuwu na ndozi gburugburu ebe obibi.
   • CMC: Sodium carboxymethyl cellulose nwere ọtụtụ ọrụ dị iche iche n'ọtụtụ ụlọ ọrụ, gụnyere nri na ihe ọṅụṅụ (dịka ihe na-eme ka ihe sie ike na ihe na-eme ka ihe sie ike), ọgwụ (dịka ihe na-ejikọ ma na-agbaze), ngwaahịa nlekọta onwe onye (dịka ihe na-agbanwe rheology), ákwà (dịka ihe na-emepụta nha), na imepụta akwụkwọ (dịka ihe mgbakwunye akwụkwọ).

Ọ bụ ezie na ma polyanionic cellulose (PAC) na sodium carboxymethyl cellulose (CMC) bụ ihe ndị sitere na cellulose nwere ihe onwunwe anionic na ojiji yiri ya n'ụfọdụ ụlọ ọrụ, ha nwere ọdịiche dị iche iche n'ihe gbasara nhazi kemịkalụ, ihe onwunwe, na ojiji kpọmkwem. A na-ejikarị PAC eme ihe n'ụlọ ọrụ mmanụ na gas, ebe CMC na-achọta ngwa sara mbara na nri, ọgwụ, nlekọta onwe onye, ​​​​ákwà, na ụlọ ọrụ ndị ọzọ.
