Polyanionic cellulose (PAC) uye sodium carboxymethyl cellulose (CMC) imhando mbiri dze cellulose ether dzine akafanana makemikari zvimiro uye zvimiro, asi akasiyana mune zvimwe zvakakosha zvinhu.

PAC is water-soluble cellulose ether ine yakakwira dhigirii yekutsiva, zvichireva kuti nhamba huru yemapoka ecarboxymethyl akabatanidzwa kune cellulose musana. PAC inowanzo shandiswa seviscosifier uye yekurasikirwa kwemvura inoderedza mumvura yekuchera mafuta nekuda kwekuchengetedza kwayo mvura zvakanaka, kugadzikana, uye kukora zvivakwa.

CMC, kune rumwe rutivi, imvura-inonyungudika cellulose ether iyo inoshandiswa zvakanyanya seyakakora, binder, uye stabilizer mumaindasitiri akasiyana siyana, kusanganisira chikafu, mishonga, zvizorwa, uye kugadzira mapepa. CMC inogadzirwa nekuita kwe cellulose ine monochloroacetic acid kuunza mapoka ecarboxymethyl mumusana we cellulose. Iyo dhigirii yekutsiva CMC yakaderera pane iyo yePAC, asi ichiri kupa yakanaka kuchengetedza kwemvura, kugadzikana, uye kukora zvivakwa.

Kunyangwe ese ari maviri PAC neCMC ari cellulose ether ane akafanana zvivakwa, anosiyana mune zvimwe zvakakosha zvinhu. Semuyenzaniso, PAC inowanzo shandiswa muindasitiri yekuchera oiri nekuda kweiyo yakakwira dhigirii yekutsiva uye yakanakisa kurasikirwa kwemvura kudzikisa zvivakwa, nepo CMC ichishandiswa muhupamhi hwemaindasitiri nekuda kwedhigirii rayo rekutsiva uye kuita zvakasiyana mukushandisa kwakasiyana.

Pakazere, PAC neCMC ese ari maviri akakosha cellulose ether ane akasiyana zvivakwa uye mashandisirwo. Nepo PAC ichinyanya kushandiswa muindasitiri yekuchera oiri, CMC ine huwandu hwakakura hwemashandisirwo mumaindasitiri akasiyana nekuda kwekusiyana kwayo uye kuderera kwedhigirii rekutsiva.
