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

Polyanionic cellulose (PAC) le sodium carboxymethyl cellulose (CMC) ka bobeli ke lintho tse nkiloeng ho cellulose tse sebelisoang haholo liindastering tse fapaneng bakeng sa thepa ea tsona ea ho tenya, ea botsitso le ea rheological.Le ha ba arolelana lintho tse ling tse tšoanang, ba boetse ba na le phapang e fapaneng mabapi le sebopeho sa lik'hemik'hale, thepa le ts'ebeliso.Papiso lipakeng tsa PAC le CMC ke ena:

1. Sebopeho sa Lik'hemik'hale:
   • PAC: Polyanionic cellulose ke polima e qhibilihang ka metsing e nkiloeng ho selulose ka ho kenya carboxymethyl le lihlopha tse ling tsa anionic mokokotlong oa cellulose.E na le lihlopha tse ngata tsa carboxyl (-COO-) haufi le ketane ea cellulose, e etsang hore e be anionic haholo.
   • CMC: Sodium carboxymethyl cellulose le eona ke polima e qhibilihang ka metsing e tsoang selulose, empa e kena tšebetsong e itseng ea carboxymethylation, e bakang ho nkeloa sebaka ha lihlopha tsa hydroxyl (-OH) le lihlopha tsa carboxymethyl (-CH2COONa).CMC hangata e na le lihlopha tse fokolang tsa carboxyl ha li bapisoa le PAC.
2. Tlhaho ea Ionic:
   • PAC: Polyanionic cellulose e na le anionic haholo ka lebaka la boteng ba lihlopha tse ngata tsa carboxyl haufi le ketane ea cellulose.E bonts'a thepa e matla ea phapanyetsano ea ion 'me e atisa ho sebelisoa e le moemeli oa ho laola ho hloekisa le ho fetola rheology ka maro a ho cheka metsi.
   • CMC: Sodium carboxymethyl cellulose le eona ke anionic, empa tekanyo ea eona ea anionicity e itšetlehile ka tekanyo ea ho kenya sebaka (DS) ea lihlopha tsa carboxymethyl.CMC e atisa ho sebelisoa e le motenya, stabilizer, le viscosity modifier lits'ebetsong tse fapaneng, ho kenyeletsoa lijo, meriana, le lihlahisoa tsa tlhokomelo ea motho.
3. Viscosity le Rheology:
   • PAC: Polyanionic cellulose e bonts'a viscosity e phahameng le boits'oaro bo tšesaane ba ho kuta ka tharollo, e etsa hore e sebetse joalo ka mofetoleli o motenya le oa rheology mokelikeli oa ho cheka le lits'ebetso tse ling tsa indasteri.PAC e khona ho mamella mocheso o phahameng le maemo a letsoai a fumanehang ts'ebetsong ea sebaka sa oli.
   • CMC: Sodium carboxymethyl cellulose e boetse e bonts'a viscosity le thepa ea ho fetola rheology, empa viscosity ea eona hangata e tlase ha e bapisoa le PAC.CMC e theha tharollo e tsitsitseng le ea pseudoplastic, e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea likopo, ho kenyeletsoa lijo, litlolo le meriana.
4. Lisebelisoa:
   • PAC: Polyanionic cellulose e sebelisoa haholo indastering ea oli le khase e le moemeli oa ho laola ho hloekisa, ho fetola rheology le ho fokotsa tahlehelo ea mokelikeli mekelikeli ea ho cheka.E boetse e sebelisoa lits'ebetsong tse ling tsa indasteri tse kang thepa ea kaho le tokiso ea tikoloho.
   • CMC: Sodium carboxymethyl cellulose e na le lits'ebetso tse fapaneng liindastering tse fapaneng, ho kenyeletsoa lijo le lino (joalo ka sekontiri le se tsitsitseng), meriana (e le setlamo le sehlaseli), lihlahisoa tsa tlhokomelo ea motho (joalo ka rheology modifier), masela (e le sesebelisoa sa boholo) , le tlhahiso ea pampiri (e le tlatsetso ea pampiri).

athe polyanionic cellulose (PAC) le sodium carboxymethyl cellulose (CMC) e le lintho tse nkiloeng ho cellulose tse nang le thepa ea anionic le lits'ebetso tse ts'oanang liindastering tse ling, li na le phapang e ikhethang mabapi le sebopeho sa lik'hemik'hale, thepa le lits'ebetso tse ikhethileng.PAC e sebelisoa haholo indastering ea oli le khase, ha CMC e fumana lits'ebetso tse pharalletseng lijong, meriana, tlhokomelong ea motho, masela le liindasteri tse ling.
