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

Polyanionic cellulose (PAC) na sodium carboxymethyl cellulose (CMC) bụ ma cellulose mmepụta nke a na-ejikarị na ụlọ ọrụ dị iche iche maka ịgbatị ha, nkwụsi ike, na rheological Njirimara. Ọ bụ ezie na ha na-ekerịta ụfọdụ myirịta, ha nwekwara ndịiche dị iche iche n'ihe gbasara usoro kemịkalụ, akụrụngwa na ngwa. Nke a bụ ntụnyere n'etiti PAC na CMC:

1. Ọdịdị kemịkal:
   • PAC: Polyanionic cellulose bụ polymer soluble mmiri nke ewepụtara na cellulose site na iwebata carboxymethyl na otu anionic ndị ọzọ n'ime ọkpụkpụ azụ cellulose. O nwere otutu carboxyl otu (-COO-) tinyere agbụ cellulose, na-eme ka ọ bụrụ anionic nke ukwuu.
   • CMC: sodium carboxymethyl cellulose bụkwa a mmiri-soluble polima ewepụtara si cellulose, ma ọ na-enweta a kpọmkwem carboxymethylation usoro, butere na nnọchi nke hydroxyl otu (-OH) na carboxymethyl otu (-CH2COONa). CMC na-enwekarị otu carboxyl ole na ole ma e jiri ya tụnyere PAC.
2. Ọdịdị Ionic:
   • PAC: Polyanionic cellulose bụ nnukwu anionic n'ihi ọnụnọ nke ọtụtụ carboxyl dị n'akụkụ eriri cellulose. Ọ na-egosipụta ikike mgbanwe ion siri ike ma na-ejikarị ya dị ka onye na-ahụ maka nchịkwa nzacha na rheology modifier na mmiri mmiri na-egwupụta mmiri.
   • CMC: Sodium carboxymethyl cellulose bụkwa anionic, mana ogo nke anionicity ya dabere na ogo nnọchi (DS) nke otu carboxymethyl. A na-ejikarị CMC eme ihe dị ka thickener, stabilizer, na viscosity modifier na ngwa dị iche iche, gụnyere nri, ọgwụ na ngwaahịa nlekọta onwe onye.
3. Viscosity na Rheology:
   • PAC: Polyanionic cellulose na-egosiputa viscosity dị elu na omume na-akpachapụ anya na ngwọta, na-eme ka ọ dị irè dị ka ihe na-eme ka ọkpụkpụ na rheology modifier na-egwupụta mmiri na ngwa mmepụta ihe ndị ọzọ. PAC nwere ike iguzogide oke okpomọkụ na ọkwa salinity zutere na ọrụ mmanụ.
   • CMC: Sodium carboxymethyl cellulose na-egosipụtakwa viscosity na rheology mgbanwe Njirimara, ma viscosity ya na-adịkarị ala ma e jiri ya tụnyere PAC. CMC na-emepụta ihe nkwụsi ike na pseudoplastic, na-eme ka ọ dabara maka ngwa dịgasị iche iche, gụnyere nri, ihe ịchọ mma, na ọgwụ.
4. Ngwa:
   • PAC: A na-eji polyanionic cellulose eme ihe na ụlọ ọrụ mmanụ na gas dị ka onye na-ahụ maka njikwa filtration, rheology modifier, na ihe na-ebelata mmiri mmiri na-egwupụta mmiri. A na-ejikwa ya na ngwa ụlọ ọrụ ndị ọzọ dị ka ihe owuwu na nhazi gburugburu ebe obibi.
   • CMC: Sodium carboxymethyl cellulose nwere ngwa dịgasị iche iche na ụlọ ọrụ dị iche iche, gụnyere nri na ihe ọṅụṅụ (dị ka onye na-agba ume na stabilizer), ọgwụ (dị ka ihe nkedo na disintegrant), ngwaahịa nlekọta onwe onye (dị ka onye na-agbanwe rheology), textiles (dị ka onye na-emepụta ihe). , na imepụta akwụkwọ (dị ka ihe mgbakwunye akwụkwọ).

ebe ma polyanionic cellulose (PAC) na sodium carboxymethyl cellulose (CMC) bụ cellulose mmepụta na anionic Njirimara na yiri ngwa na ụfọdụ ọrụ, ha nwere iche iche na okwu nke chemical Ọdịdị, Njirimara, na kpọmkwem ngwa. A na-eji PAC eme ihe na ụlọ ọrụ mmanụ na gas, ebe CMC na-ahụ ngwa ngwa na nri, ọgwụ, nlekọta onwe onye, ​​akwa akwa na ụlọ ọrụ ndị ọzọ.
