Te Pūtauira Pōranioni (PAC) me te Pūtauira Kāpohaimetila Konutai (CMC)

Ko te polyanionic cellulose (PAC) me te sodium carboxymethyl cellulose (CMC) he mea hanga mai i te cellulose e whakamahia whānuitia ana i roto i ngā ahumahi maha mō ō rāua āhuatanga whakamātotoru, whakaū, me te rheological. Ahakoa he rite tonu ō rāua āhuatanga, he rerekētanga motuhake anō hoki i roto i te hanganga matū, ngā āhuatanga, me ngā whakamahinga. Anei te whakataurite i waenga i te PAC me te CMC:

1. Hanganga Matū:
   • PAC: Ko te cellulose polyanionic he pūhui wairewa-wai i ahu mai i te cellulose mā te whakaurunga o te carboxymethyl me ētahi atu rōpū anionic ki te tuara o te cellulose. Kei roto he maha ngā rōpū carboxyl (-COO-) i te mekameka cellulose, ā, he tino anionic.
   • CMC: He pūhui wairewa-wai anō hoki te konutai carboxymethyl cellulose i ahu mai i te cellulose, engari ka pāngia e tētahi tukanga carboxymethylation motuhake, ka hua ake te whakakapinga o ngā rōpū hydroxyl (-OH) ki ngā rōpū carboxymethyl (-CH2COONa). He iti ake ngā rōpū carboxyl i roto i te CMC ki te whakataurite ki te PAC.
2. Te Āhua Ionic:
   • PAC: He tino anionic te cellulose polyanionic nā te mea he maha ngā rōpū carboxyl i te mekameka cellulose. He kaha ōna āhuatanga whakawhiti-katote, ā, he maha ngā wā ka whakamahia hei kaiwhakahaere tātari me te whakarerekē rheology i roto i ngā wai keri wai.
   • CMC: He anionic anō hoki te konutai carboxymethyl cellulose, engari ko tōna taumata anionicity e whakawhirinaki ana ki te taumata o te whakakapinga (DS) o ngā rōpū carboxymethyl. E whakamahia whānuitia ana te CMC hei whakamātotoru, hei whakaū, hei whakarerekē matotoru hoki i roto i ngā momo tono, tae atu ki te kai, ngā rongoā, me ngā hua tiaki whaiaro.
3. Te Matatini me te Rheology:
   • PAC: He nui te matotoru me te āhua angiangi o te cellulose polyanionic i roto i te wairewa, ā, he whai hua hei whakamātotoru me te whakarerekē i te rheology i roto i ngā wai keri me ētahi atu tono ahumahi. Ka taea e te PAC te tu atu i ngā pāmahana teitei me ngā taumata tote e tūpono ana ki ngā mahi mara hinu.
   • CMC: Kei roto hoki i te konutai carboxymethyl cellulose ngā āhuatanga matotoru me te whakarerekētanga rheology, engari he iti ake te matotoru i te PAC. Ka hangaia e te CMC he otinga pumau ake, he rūpahu hoki, e pai ai mō te whānuitanga o ngā tono, tae atu ki te kai, ngā mea whakapaipai, me ngā rongoā.
4. Ngā tono:
   • PAC: Ko te cellulose polyanionic te mea e whakamahia nuitia ana i roto i te umanga hinu me te hau hei kaiwhakahaere tātari, hei whakarerekē rheology, hei whakaiti i te ngaronga wai i roto i ngā wai keri. E whakamahia ana hoki i roto i ētahi atu tono ahumahi pēnei i ngā rauemi hanga me te whakaora taiao.
   • CMC: He maha ngā whakamahinga o te konutai carboxymethyl cellulose i roto i ngā ahumahi rerekē, tae atu ki te kai me te inu (hei whakamātotoru me te whakaū), ngā rongoā (hei here me te whakarewa), ngā hua tiaki whaiaro (hei whakarerekētanga rheology), ngā kakahu (hei kaihoko rahi), me te hanga pepa (hei tāpiri pepa).

Ahakoa he mea hanga mai i te cellulose te polyanionic cellulose (PAC) me te sodium carboxymethyl cellulose (CMC) me ōna āhuatanga anionic me ōna whakamahinga rite tonu i roto i ētahi ahumahi, he rerekētanga motuhake kei roto i te hanganga matū, ngā āhuatanga, me ngā whakamahinga motuhake. Ko te PAC te mea nui e whakamahia ana i roto i te ahumahi hinu me te hau, ko te CMC ia he whānui te whakamahinga i roto i te kai, te rongoā, te tiaki whaiaro, te kakahu, me ētahi atu ahumahi.
