Polyanionic cellulose (PAC) hakika polymer ne, mai mahimmanci a masana'antu daban-daban, musamman wajen hakowa da hako mai.Don fahimtar mahimmanci da kaddarorin cellulose na polyanionic, bari mu fara bincike cikin abubuwan da ke tattare da shi, da amfaninsa, da kuma abubuwan da ke tattare da shi a sassa daban-daban.
A ainihinsa, polyanionic cellulose wani nau'i ne na cellulose, wani nau'in polymer na halitta wanda aka samo a cikin ganuwar tantanin halitta.Cellulose kanta shine polysaccharide wanda ya ƙunshi raka'o'in glucose wanda aka haɗa tare da β(1→4) glycosidic bonds.Wannan tsari yana ba wa cellulose ƙarfin halayensa da tsattsauran ra'ayi, yana mai da shi muhimmin sashi na tsari a cikin tsire-tsire.Duk da haka, ana iya gyaggyarawa da haɓaka abubuwan da ke tattare da cellulose don dacewa da aikace-aikacen masana'antu daban-daban, wanda ke haifar da haɓaka abubuwan da suka samo asali kamar polyanionic cellulose.
Polyanionic cellulose yana haɗe ta hanyar gyare-gyaren sinadarai na cellulose, inda ƙungiyoyin hydroxyl (-OH) da ke cikin kwayoyin halitta suna maye gurbin su da ƙungiyoyin carboxymethyl (-CH2COOH).Wannan gyare-gyare yana ba da halayen anionic zuwa kashin bayan cellulose, wanda ya haifar da polymer tare da abubuwan polyanionic.Matsayin maye gurbin (DS) yana ƙayyade iyakar maye gurbin carboxymethyl akan kashin bayan cellulose, yana tasiri ga kaddarorin da aikace-aikacen polymer gabaɗaya.
Ɗaya daga cikin mahimman aikace-aikacen polyanionic cellulose shine a cikin masana'antar mai da iskar gas, musamman a cikin hakowa.Ruwan hakowa, wanda aka fi sani da laka, suna yin ayyuka daban-daban yayin ayyukan hakowa, gami da mai, sanyaya, da kawar da tarkace.Ana ƙara polyanionic cellulose zuwa ruwa mai hakowa azaman viscosifier da wakili na sarrafa asarar ruwa.
A matsayin viscosifier, polyanionic cellulose yana ba da kaddarorin rheological don hako ruwa, yana haɓaka ikon su na dakatar da yankan haƙora da kiyaye kwanciyar hankali.Babban kayan aikin polymer na polymer da yanayin anionic ya ba shi damar samar da tsarin cibiyar sadarwa a cikin ruwa, ƙara danko da hana daskarewa ko magance daskararru.Bugu da ƙari, polyanionic cellulose yana nuna kyakkyawan haƙurin gishiri, yana mai da shi dacewa don amfani da shi a cikin yanayin hakowa mai yawan gishiri wanda aka saba da shi a ayyukan hakowa na teku.
Baya ga rawar da yake takawa a matsayin viscosifier, polyanionic cellulose yana aiki azaman wakili mai sarrafa asarar ruwa a cikin hakowa.Ta hanyar ƙirƙirar kek ɗin tacewa na bakin ciki, wanda ba zai iya jurewa ba akan bangon rijiyar, polymer yana taimakawa rage asarar ruwa cikin samuwar, ta haka yana riƙe da matsi mai kyau da kuma hana lalacewar samuwar.Wannan kadarar tana da mahimmanci don haɓaka ingancin hakowa da rage haɗarin aiki.
Bayan sashin mai da iskar gas, polyanionic cellulose yana samun aikace-aikace a wasu masana'antu daban-daban, gami da magunguna, abinci, da kayan kwalliya.A cikin ƙirar magunguna, yana aiki azaman ɗaure, rarrabuwa, ko mai gyara danko a masana'antar kwamfutar hannu da dakatarwar baki.A cikin masana'antar abinci, ana amfani da polyanionic cellulose azaman wakili mai kauri, mai ƙarfi, ko emulsifier a cikin samfuran da suka kama daga miya da riguna zuwa samfuran kiwo da abubuwan sha.Halin yanayin halittarsa da yanayin rashin mai guba ya sa ya dace don amfani a cikin samfuran kulawa na sirri kamar su lotions, creams, da shampoos, inda yake aiki azaman mai kauri ko dakatarwa.
Polyanionic cellulose yana tsaye a matsayin madaidaicin polymer tare da aikace-aikacen tartsatsi a cikin masana'antu da yawa.Kaddarorinsa na musamman, waɗanda aka samo daga gyare-gyaren cellulose, sun sa ya zama dole a sassa kamar mai da gas, magunguna, abinci, da kayan shafawa.Yayin da bincike da ci gaban fasaha ke ci gaba, ana sa ran amfanin polyanionic cellulose zai ƙara faɗaɗa, yana ba da gudummawa ga ƙirƙira da inganci a fannoni daban-daban.
