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

Polyanionic cellulose (PAC) iyo sodium carboxymethyl cellulose (CMC) waa labada derivatives cellulose si weyn loogu isticmaalo warshadaha kala duwan si ay u dhumuc, xasilinta, iyo sifooyinka rheological.In kasta oo ay wadaagaan qaar ay isaga mid yihiin, waxay sidoo kale leeyihiin farqi u gaar ah marka loo eego qaab-dhismeedka kiimikada, guryaha, iyo codsiyada.Waa kan isbarbardhigga u dhexeeya PAC iyo CMC:

1. Qaab dhismeedka Kiimikada:
   • PAC: Polyanionic cellulose waa polymer biyo-milmi leh oo laga helay cellulose iyadoo la gelinayo karboxymethyl iyo kooxaha kale ee anionic ee lafta dhabarka cellulose.Waxay ka kooban tahay kooxo badan oo kaarboxyl ah (-COO-) oo ay weheliyaan silsiladda cellulose, taasoo ka dhigaysa anionic aad u sarreeya.
   • CMC: Sodium carboxymethyl cellulose sidoo kale waa polymer biyo-milmi leh oo ka soo jeeda cellulose, laakiin waxa ay martaa habka carboxymethylation gaar ah, taasoo keentay in beddelka kooxaha hydroxyl (-OH) oo leh kooxaha carboxymethyl (-CH2COONa).CMC caadi ahaan waxa ku jira kooxo kaarboxyl ka yar marka loo eego PAC.
2. Dabeecadda Ionic:
   • PAC: Polyanionic cellulose waa anionic aad u sarreeya sababtoo ah joogitaanka kooxo badan oo karboksyl ah oo weheliya silsiladda cellulose.Waxay soo bandhigtaa sifooyin is-dhaafsi oo xoog leh waxaana badanaa loo isticmaalaa sidii wakiilka xakamaynta shaandhaynta iyo beddelka rheology ee dareeraha qodista biyaha ku salaysan.
   • CMC: Sodium carboxymethyl cellulose sidoo kale waa anionic, laakiin heerka anionicity waxay ku xiran tahay heerka beddelka (DS) ee kooxaha karboxymethyl.CMC waxaa caadi ahaan loo isticmaalaa sidii dhumuc, xasiliye, iyo wax ka beddelka viscosity codsiyo kala duwan, oo ay ku jiraan cuntada, daawooyinka, iyo alaabta daryeelka shakhsi ahaaneed.
3. Viscosity iyo Rheology:
   • PAC: Polyanionic cellulose waxay muujisaa viscosity sare iyo dabeecad khafiifinta xiirid ee xalka, taasoo ka dhigaysa mid wax ku ool ah sidii dhumuc iyo wax ka beddelka rheology ee dareeraha qodista iyo codsiyada kale ee warshadaha.PAC waxay u adkeysan kartaa heerkulka sare iyo heerarka milixda ee ay kala kulmaan hawlgallada goobaha saliidda.
   • CMC: Sodium carboxymethyl cellulose waxa kale oo ay muujisaa muuqalka iyo sifooyinka wax ka beddelka rheology-ga, laakiin muuqashadiisu caadi ahaan waa ka hooseeyaa marka loo eego PAC.CMC waxay samaysaa xalal xasiloon oo pseudoplastic ah, taasoo ka dhigaysa mid ku habboon codsiyo badan oo kala duwan, oo ay ku jiraan cuntada, waxyaalaha la isku qurxiyo, iyo dawooyinka.
4. Codsiyada:
   • PAC: Polyanionic cellulose waxaa ugu horrayn loo adeegsadaa warshadaha saliidda iyo gaaska sida wakiilka xakamaynta sifaynta, beddelka rheology, iyo yaraynta dareeraha luminta dareeraha qodista.Waxa kale oo loo isticmaalaa codsiyada kale ee warshadaha sida qalabka dhismaha iyo hagaajinta deegaanka.
   • CMC: Sodium carboxymethyl cellulose waxay leedahay codsiyo kala duwan oo ku saabsan warshado kala duwan, oo ay ku jiraan cuntada iyo cabitaanka (sida dhumuc weyn iyo xasiliye), daawooyinka (sida binder iyo disintegrate), alaabta daryeelka shakhsi ahaaneed (sida wax ka beddelka rheology), dunta (sida wakiilka cabbirka) , iyo samaynta waraaqaha (sida wax lagu daro warqad ah).

halka labadaba polyanionic cellulose (PAC) iyo sodium carboxymethyl cellulose (CMC) ay yihiin derivatives cellulose leh guryaha anionic iyo codsiyada la mid ah in warshadaha qaar ka mid ah, waxay leeyihiin kala duwanaansho kala duwan marka la eego qaab-dhismeedka kiimikada, guryaha, iyo codsiyada gaarka ah.PAC waxaa inta badan loo isticmaalaa warshadaha saliidda iyo gaaska, halka CMC ay ka hesho codsiyo ballaaran xagga cuntada, dawooyinka, daryeelka shakhsi ahaaneed, dunta, iyo warshadaha kale.
