Cellulose ea Polyanionic (PAC) le Cellulose ea Sodium Carboxymethyl (CMC)
Polyanionic cellulose (PAC) le sodium carboxymethyl cellulose (CMC) ka bobeli ke di-derivatives tsa cellulose tse sebediswang haholo diindastering tse fapaneng bakeng sa thepa ya tsona ya ho teteana, ho tsitsisa le ho rheological. Le hoja di tshwana ka ho tshwana, di boetse di na le dipharologanyo tse fapaneng mabapi le sebopeho sa dikhemikhale, thepa le ditshebediso. Mona ke papiso pakeng tsa PAC le CMC:
- Sebopeho sa Lik'hemik'hale:
- PAC: Polyanionic cellulose ke polymer e qhibilihang ka metsing e nkiloeng ho cellulose ka ho kenyelletsa carboxymethyl le lihlopha tse ling tsa anionic mokokotlong oa cellulose. E na le lihlopha tse ngata tsa carboxyl (-COO-) ho pholletsa le ketane ea cellulose, e leng se etsang hore e be anionic haholo.
- CMC: Sodium carboxymethyl cellulose le yona ke polymer e qhibilihang ka metsing e tswang ho cellulose, empa e feta tshebetsong e ikgethang ya carboxymethylation, e leng se fellang ka hore dihlopha tsa hydroxyl (-OH) di nkelwe sebaka ke dihlopha tsa carboxymethyl (-CH2COONa). Hangata CMC e na le dihlopha tse fokolang tsa carboxyl ha e bapiswa le PAC.
- Tlhaho ea Ionic:
- PAC: Polyanionic cellulose e na le anionic e ngata ka lebaka la boteng ba lihlopha tse ngata tsa carboxyl ho potoloha ketane ea cellulose. E bontša thepa e matla ea phapanyetsano ea ion 'me hangata e sebelisoa e le sesebelisoa sa taolo ea ho sefa le phetoho ea rheology marong a ho cheka a thehiloeng metsing.
- CMC: Sodium carboxymethyl cellulose le yona ke anionic, empa tekanyo ya yona ya anionicity e itshetlehile ka tekanyo ya phetolo (DS) ya dihlopha tsa carboxymethyl. CMC e sebediswa hangata e le sesebelisoa sa ho teteanya, ho tsitsisa le ho fetola viscosity dikopong tse fapaneng, ho kenyeletswa dijo, meriana le dihlahiswa tsa tlhokomelo ya motho ka mong.
- Ho thothomela le Rheology:
- PAC: Polyanionic cellulose e bonts'a viscosity e phahameng le boits'oaro ba ho fokotsa ho kuta ha oli ka har'a tharollo, e leng se etsang hore e sebetse hantle e le sesebelisoa sa ho teteana le ho fetola rheology marong a ho tjheka le lits'ebetsong tse ling tsa indasteri. PAC e ka mamella mocheso o phahameng le maemo a letsoai a kopanang le ts'ebetso ea oli.
- CMC: Sodium carboxymethyl cellulose le yona e bontsha bokgoni ba ho fetola viscosity le rheology, empa viscosity ya yona hangata e tlase ha e bapiswa le PAC. CMC e etsa ditharollo tse tsitsitseng le tse sa bonahaleng, e leng se etsang hore e lokele mefuta e mengata ya ditshebediso, ho kenyeletswa dijo, ditlolo le meriana.
- Likopo:
- PAC: Polyanionic cellulose e sebediswa haholoholo indastering ya oli le kgase e le sesebelisoa sa taolo ya ho sefa, ho fetola rheology, le ho fokotsa tahlehelo ya mokelikeli marong a ho tjheka. E boetse e sebediswa dikopong tse ding tsa indasteri tse kang thepa ya kaho le tokiso ya tikoloho.
- CMC: Sodium carboxymethyl cellulose e na le ditiriso tse fapaneng diindastering tse fapaneng, ho kenyeletswa dijo le dino (e le sethibela-mafu le se tsitsisang), meriana (e le se kopanyang le se qhalang), dihlahiswa tsa tlhokomelo ya motho ka mong (e le modifier ya rheology), masela (e le moemeli wa boholo), le tlhahiso ya pampiri (e le sehlomathiso sa pampiri).
Leha polyanionic cellulose (PAC) le sodium carboxymethyl cellulose (CMC) ka bobedi e le di-derivatives tsa cellulose tse nang le thepa ya anionic le ditshebediso tse tshwanang diindastering tse ding, di na le dipharologanyo tse fapaneng mabapi le sebopeho sa dikhemikhale, thepa le ditshebediso tse ikgethang. PAC e sebediswa haholoholo indastering ya oli le kgase, ha CMC e fumana ditshebediso tse pharaletseng dijong, meriana, tlhokomelong ya botho, masela le diindastering tse ding.
