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

Polyanionic cellulose (PAC) da sodium carboxymethyl cellulose (CMC) dukkansu suna da alaƙa da cellulose waɗanda ake amfani da su sosai a masana'antu daban-daban don kauri, daidaito, da kuma halayen rheological. Duk da cewa suna da wasu kamanceceniya, suna kuma da bambance-bambance daban-daban dangane da tsarin sinadarai, halaye, da aikace-aikace. Ga kwatancen tsakanin PAC da CMC:

1. Tsarin Sinadarai:
   • PAC: Polyanionic cellulose wani polymer ne mai narkewar ruwa wanda aka samo daga cellulose ta hanyar gabatar da carboxymethyl da sauran ƙungiyoyin anionic zuwa kashin bayan cellulose. Yana ɗauke da ƙungiyoyin carboxyl da yawa (-COO-) tare da sarkar cellulose, wanda hakan ya sa ya zama anionic sosai.
   • CMC: Sodium carboxymethyl cellulose shima polymer ne mai narkewa cikin ruwa wanda aka samo daga cellulose, amma yana fuskantar wani takamaiman tsarin carboxymethylation, wanda ke haifar da maye gurbin ƙungiyoyin hydroxyl (-OH) da ƙungiyoyin carboxymethyl (-CH2COONa). CMC yawanci yana ɗauke da ƙarancin ƙungiyoyin carboxyl idan aka kwatanta da PAC.
2. Yanayin Ionic:
   • PAC: Polyanionic cellulose yana da matuƙar anionic saboda kasancewar ƙungiyoyin carboxyl da yawa a kan sarkar cellulose. Yana nuna ƙarfin ikon musayar ion kuma galibi ana amfani da shi azaman wakilin sarrafa tacewa da kuma mai gyara rheology a cikin ruwan haƙa mai tushen ruwa.
   • CMC: Sodium carboxymethyl cellulose shima anionic ne, amma matakin anionicity ɗinsa ya dogara da matakin maye gurbin (DS) na ƙungiyoyin carboxymethyl. Ana amfani da CMC a matsayin mai kauri, mai daidaita, da kuma mai canza danko a aikace-aikace daban-daban, gami da abinci, magunguna, da kayayyakin kulawa na mutum.
3. Danko da Rhology:
   • PAC: Polyanionic cellulose yana nuna yawan danko da kuma rage kitse a cikin ruwan da aka tace, wanda hakan ke sa shi ya zama mai tasiri a matsayin mai kauri da kuma mai gyara rheology a cikin ruwan hakowa da sauran aikace-aikacen masana'antu. PAC na iya jure yanayin zafi da matakan gishirin da ake fuskanta a ayyukan filin mai.
   • CMC: Sodium carboxymethyl cellulose shima yana nuna danko da kuma gyaran rheology, amma dankonsa yawanci yana da kasa idan aka kwatanta da PAC. CMC yana samar da mafita masu karko da na roba, wanda hakan ya sa ya dace da amfani iri-iri, ciki har da abinci, kayan kwalliya, da magunguna.
4. Aikace-aikace:
   • PAC: Polyanionic cellulose ana amfani da shi ne musamman a masana'antar mai da iskar gas a matsayin maganin tacewa, gyaran rheology, da kuma rage asarar ruwa a cikin ruwan haƙa. Haka kuma ana amfani da shi a wasu aikace-aikacen masana'antu kamar kayan gini da gyaran muhalli.
   • CMC: Sodium carboxymethyl cellulose yana da aikace-aikace daban-daban a masana'antu daban-daban, ciki har da abinci da abin sha (a matsayin mai kauri da mai daidaita), magunguna (a matsayin abin ɗaurewa da mai wargazawa), kayayyakin kulawa na mutum (a matsayin mai gyara rheology), yadi (a matsayin wakilin girma), da kuma kera takarda (a matsayin ƙarin takarda).

Yayin da polyanionic cellulose (PAC) da sodium carboxymethyl cellulose (CMC) duka samfuran cellulose ne masu halayen anionic da aikace-aikace makamancin haka a wasu masana'antu, suna da bambance-bambance daban-daban dangane da tsarin sinadarai, halaye, da takamaiman aikace-aikace. Ana amfani da PAC galibi a masana'antar mai da iskar gas, yayin da CMC ke samun aikace-aikace masu faɗi a abinci, magunguna, kulawa ta mutum, yadi, da sauran masana'antu.
