Polyanionic selulose (PAC) na sodium carboxymethyl selulose (CMC) nubwoko bubiri bwa selile ya selile ifite imiterere nubumaro bisa, ariko bitandukanye mubice bimwe byingenzi.

PAC ni amazi ya elegitoronike ya selile yamashanyarazi afite urwego rwo hejuru rwo gusimbuza, bivuze ko umubare munini wamatsinda ya carboxymethyl yometse kumugongo wa selile. PAC isanzwe ikoreshwa nka viscosifier na kugabanya gutakaza amazi mumazi yo gucukura amavuta kubera kubika neza kwamazi, gutuza, hamwe nubunini.

Ku rundi ruhande, CMC, ni eferi ya elegitoronike ya elegitoronike ikoreshwa cyane mu rwego rwo kubyimba, guhuza, hamwe na stabilisateur mu nganda zitandukanye, harimo ibiryo, imiti, amavuta yo kwisiga, no gukora impapuro. CMC ikorwa nigikorwa cya selile hamwe na acide monochloroacetic kugirango yinjize amatsinda ya carboxymethyl mumugongo wa selile. Urwego rwo gusimbuza CMC ruri munsi ya PAC, ariko iracyatanga amazi meza, ituze, hamwe nubunini.

Nubwo PAC na CMC byombi ari selile ethers ifite imitungo isa, iratandukanye mubice bimwe byingenzi. Kurugero, PAC isanzwe ikoreshwa mubikorwa byo gucukura peteroli kubera urwego rwo hejuru rwo gusimbuza no kugabanya igihombo cyiza cyo kugabanya amazi, mugihe CMC ikoreshwa mubikorwa bitandukanye byinganda bitewe nubushobozi buke bwo gusimbuza no guhinduranya mubikorwa bitandukanye.

Muri rusange, PAC na CMC byombi ni selile yingenzi ya selile hamwe nibintu byihariye hamwe nibisabwa. Mu gihe PAC ikoreshwa cyane cyane mu nganda zicukura peteroli, CMC ifite uburyo bwinshi bwo gukoresha mu nganda zinyuranye bitewe nuburyo bwinshi ndetse n’ubushobozi buke bwo gusimburwa.
