Ese polyanionic selulose ni polymer？

Polyanionic selulose (PAC) mubyukuri ni polymer, ingenzi mubikorwa bitandukanye, cyane cyane mu gucukura no gucukura peteroli. Kugira ngo twumve akamaro n'imiterere ya selile ya polyanionic, reka dutangire ubushakashatsi mubigize, imikoreshereze, nibisobanuro mubice bitandukanye.

Muri rusange, selile ya polyanionic ni inkomoko ya selile, polimeri isanzwe ibaho iboneka murukuta rw'utugingo ngengabuzima. Cellulose ubwayo ni polysaccharide igizwe na glucose ibice bihujwe hamwe na β (1 → 4) glycosidic. Iyi gahunda iha selile imbaraga zayo ziranga ubukana, bikagira ikintu cyingenzi cyubaka mubimera. Nyamara, imiterere yihariye ya selile irashobora guhindurwa no kuzamurwa kugirango ihuze nibikorwa bitandukanye byinganda, biganisha ku iterambere ryibikomoka kuri selile ya polyanionic.

Cellulose ya polyanionic ihindurwamo hifashishijwe uburyo bwo guhindura imiti ya selile, aho amatsinda ya hydroxyl (-OH) aboneka muri molekile ya selile asimbuzwa amatsinda ya carboxymethyl (-CH2COOH). Ihinduka ritanga imiterere ya anionic kumugongo wa selile, bikavamo polymer ifite imiterere ya polyanionic. Urwego rwo gusimbuza (DS) rugena urugero rwo gusimbuza carboxymethyl ku mugongo wa selile, bigira ingaruka kumiterere ya polymer hamwe nibisabwa.

Bumwe mu buryo bukoreshwa cyane muri selile ya polyanionic ni mu nganda za peteroli na gaze, cyane cyane mu gucukura amazi. Amazi yo gucukura, akunze kwitwa ibyondo, akora ibikorwa bitandukanye mugihe cyo gucukura, harimo gusiga, gukonjesha, no kuvanaho imyanda. Polyanionic selulose yongewe kumazi yo gucukura nka viscosifier na agent igenzura igihombo.

Nka viscosifier, selile ya polyanionic itanga imiterere ya rheologiya mumazi yo gucukura, bikongerera ubushobozi bwo guhagarika imyanda no gukomeza umutekano mwiza. Uburemere bukabije bwa polymer hamwe na kamere ya anionic bituma habaho imiterere y'urusobekerane mumazi, bikongera ubukonje kandi bikarinda kugabanuka cyangwa gutuza ibintu bikomeye. Byongeye kandi, selile ya polyanionic yerekana kwihanganira umunyu, bigatuma ikoreshwa muburyo bwo gucukura umunyu mwinshi usanzwe mubikorwa byo gucukura ku nyanja.

Usibye uruhare rwayo nka viscosifier, selile ya polyanionic ikora nka agent igenzura igihombo cyamazi mugucukura amazi. Mugukora cake yoroheje, idashobora kwungururwa kurukuta rwamazi, polymer ifasha kugabanya igihombo cyamazi mumiterere, bityo igakomeza kugenzura neza umuvuduko no kwirinda kwangirika. Uyu mutungo ningirakamaro mugutezimbere gucukura no kugabanya ingaruka zikorwa.

Kurenga urwego rwa peteroli na gaze, selile ya polyanionic isanga izindi nganda zitandukanye, harimo imiti, ibiryo, no kwisiga. Mu miti ya farumasi, ikora nka binder, disintegrant, cyangwa viscosity modifier mugukora ibinini no guhagarika umunwa. Mu nganda z’ibiribwa, selile ya polyanionic ikoreshwa nkibikoresho byongera umubyimba, stabilisateur, cyangwa emulisiferi mu bicuruzwa kuva ku isosi no kwambara kugeza ku mata n’ibinyobwa. Imiterere ya biocompatibilité na kamere idafite ubumara ituma ikwiriye gukoreshwa mubicuruzwa byita ku muntu nka amavuta yo kwisiga, amavuta, na shampo, aho ikora nk'umubyimba cyangwa uhagarika.

Polyanionic selulose ihagaze nka polymer itandukanye kandi ikoreshwa cyane mubikorwa byinshi. Imiterere yihariye, ikomoka ku guhindura selile, bituma iba ingenzi mu nzego nka peteroli na gaze, imiti, ibiryo, no kwisiga. Mugihe ubushakashatsi niterambere ryikoranabuhanga bikomeje, ibikorwa bya selile ya polyanionic biteganijwe ko bizagenda byiyongera, bigira uruhare mu guhanga udushya no gukora neza mubice bitandukanye.
