I-Polyanionic cellulose (PAC) kanye ne-sodium carboxymethyl cellulose (CMC) yizinhlobo ezimbili zama-cellulose ether anezakhiwo zamakhemikhali ezifanayo kanye nezakhiwo, kodwa ziyehluka kwezinye izici ezibalulekile.

I-PAC iyi-ether ye-cellulose encibilikayo emanzini enezinga eliphezulu lokushintsha, okusho ukuthi inani elikhulu lamaqembu e-carboxymethyl linamathele kumgogodla we-cellulose.I-PAC ivamise ukusetshenziswa njenge-viscosifier kanye nesinciphisi sokulahlekelwa uketshezi oketshezini lokumba uwoyela ngenxa yokugcinwa kwamanzi okuhle kakhulu, ukuzinza, kanye nezakhiwo ezijiya.

I-CMC, ngakolunye uhlangothi, iyi-ether ye-cellulose encibilika emanzini esetshenziswa kabanzi njenge-thickener, binder, kanye ne-stabilizer ezimbonini ezihlukahlukene, okuhlanganisa ukudla, imithi, izimonyo, nokukhiqizwa kwephepha.I-CMC ikhiqizwa ukusabela kwe-cellulose nge-monochloroacetic acid ukwethula amaqembu e-carboxymethyl kumgogodla we-cellulose.Izinga lokushintshwa kwe-CMC liphansi kunalelo le-PAC, kodwa isahlinzeka ngokugcinwa kwamanzi okuhle, ukuzinza, kanye nezakhiwo ezijiyayo.

Yize zombili i-PAC ne-CMC zingama-cellulose ether anezakhiwo ezifanayo, ziyahluka kwezinye izici ezibalulekile.Isibonelo, i-PAC ivamise ukusetshenziswa embonini yokumba uwoyela ngenxa yezinga layo eliphezulu lokushintsha kanye nezindawo ezinhle kakhulu zokunciphisa uketshezi olunciphayo, kuyilapho i-CMC isetshenziswa kuhlu olubanzi lwezimboni ngenxa yezinga layo eliphansi lokushintsha nokuguquguquka ekusetshenzisweni okuhlukahlukene.

Sekukonke, i-PAC ne-CMC womabili ama-cellulose ether abalulekile anezakhiwo nezindlela ezihlukile.Ngenkathi i-PAC isetshenziswa kakhulu embonini yokumba uwoyela, i-CMC inohlu olubanzi lwezinhlelo zokusebenza ezimbonini ezahlukahlukene ngenxa yokuguquguquka kwayo kanye nezinga eliphansi lokushintshwa.
