Isbarbardhigga Hantida Iska caabbinta Dheecaannada Luminta ee Cellulose Polyanionic oo ay soo saartay Habka Cajiinka

Polyanionic cellulose (PAC) waa polymer biyo-milmi leh oo laga soo qaatay cellulose waxaana caadi ahaan loo isticmaalaa wax lagu daro xakamaynta luminta dareeraha ee dareeraha qodista ee loo isticmaalo sahaminta saliidda iyo gaaska.Labada hab ee ugu muhiimsan ee soo saarista PAC waa habka cajiinka iyo habka qulqulka.Halkan waxaa ah isbarbardhigga hantida iska caabbinta dareeraha luminta ee PAC ee ay soo saartay labadan hab:

1. Habka cajiinka:
   • Habka Wax-soo-saarka: Habka cajiinka, PAC waxaa la soo saaraa iyada oo ka falcelinaysa cellulose leh alkali, sida sodium hydroxide, si loo sameeyo cajiinka cellulose alkaline.Cajiinkaan ayaa markaa lagu falcelinayaa chloroacetic acid si loogu soo bandhigo kooxaha karboksymethyl ee laf dhabarta cellulose, taasoo keentay PAC.
   • Cabbirka Qaybaha: PAC ee uu soo saaray habka cajiinka ayaa caadi ahaan leh cabbir ka weyn walxaha waxaana laga yaabaa inay ku jiraan agglomerates ama isku-darka qaybaha PAC.
   • Caabbinta Dheecaannada: PAC ee ay soo saartay habsocodka cajiinka guud ahaan waxay muujisaa caabbinta luminta dareeraha wanaagsan ee dareeraha qodista.Si kastaba ha ahaatee, xajmiga qaybta weyn iyo joogitaanka agglomerates waxay keeni kartaa fuuq-bax gaabis ah iyo kala firdhisanaanta dareeraha qodista biyaha ku salaysan, taas oo saameyn karta waxqabadka xakamaynta dareeraha, gaar ahaan heerkulka sare iyo xaaladaha cadaadiska sare.
2. Habka qulqulka:
   • Habka Wax-soo-saarka: Habka qulqulka, cellulose ayaa marka hore lagu kala firdhiyaa biyaha si ay u sameeyaan slurry, ka dibna waxaa lagu falceliyaa sodium hydroxide iyo chloroacetic acid si ay u soo saarto PAC si toos ah xalka.
   • Cabbirka Qaybaha: PAC ee uu soo saaray habka qulqulka ayaa caadi ahaan leh cabbir ka yar qayb ka mid ah oo si ka siman u kala firdhiyey xal marka loo eego PAC ee uu soo saaray habka cajiinka.
   • Iska caabbinta dareeraha lumista: PAC ee ay soo saartay habka qulqulka ayaa u janjeera inay muujiso caabbinta luminta dareeraha heer sare ah ee dareeraha qodista.Baaxadda walxaha yaryar iyo kala firdhisanaanta labbiska waxay keentaa fuuq-bax degdeg ah iyo kala firdhisanaanta dareeraha qodista biyaha ku salaysan, taasoo horseedaysa hagaajinta waxqabadka xakamaynta dareeraha, gaar ahaan xaaladaha adag ee qodista.

Labada PAC ee uu soo saaray habka cajiinka iyo PAC ee ay soo saarto habka slurry waxay bixin karaan caabbinta dareeraha wax ku oolka ah ee dareeraha qodista.Si kastaba ha ahaatee, PAC ee ay soo saartay habka qulqulka ayaa laga yaabaa inay bixiso faa'iidooyin gaar ah, sida fuuq-baxa degdega ah iyo kala firdhinta, taasoo horseedaysa kor u qaadista waxqabadka xakamaynta dareeraha, gaar ahaan heerkul sare iyo deegaan qodista cadaadis sarreeya.Ugu dambeyntii, doorashada u dhaxaysa labadan hababka wax soo saarka waxay ku xirnaan kartaa shuruudaha waxqabadka gaarka ah, tixgelinta kharashka, iyo arrimo kale oo khuseeya codsiga dareeraha qodista.
