Isbarbardhigga Hantida Iska caabinta Lumista Dareeraha ee cellulose-ka Polyanionic oo ay soo saarto Habka Cajiinka iyo Habka Slurry

Polyanionic cellulose (PAC) waa polymer-ka biyaha ku milma ee laga helo cellulose waxaana badanaa loo isticmaalaa sidii wax lagu daro xakamaynta luminta dareeraha ee dareeraha qodista ee loo isticmaalo sahaminta saliidda iyo gaaska. Labada hab ee ugu muhiimsan ee lagu soo saaro PAC waa habka cajiinka iyo habka slurry. Waa kan isbarbardhigga hantida iska caabbinta luminta dareeraha ee PAC oo ay soo saaraan labadan hab:

1. Habka Cajiinka:
   • Habka Wax Soo Saarka: Habka cajiinka, PAC waxaa lagu soo saaraa iyadoo cellulose la falgasho alkali, sida sodium hydroxide, si loo sameeyo cajiinka cellulose alkaline. Cajiinkaan waxaa lagu falgalaa chloroacetic acid si loogu soo bandhigo kooxaha carboxymethyl laf-dhabarta cellulose, taasoo keenta PAC.
   • Cabbirka Walxaha: PAC-ga ay soo saarto habka cajiinka ayaa badanaa leh cabbir walax oo weyn waxaana laga yaabaa inuu ku jiro isku-darka walxaha PAC ama isku-darka walxaha PAC.
   • Iska caabbinta Lumista Dareeraha: PAC oo ay soo saarto habka cajiinka guud ahaan waxay muujisaa iska caabbinta luminta dareeraha ee wanaagsan ee dareeraha qodista. Si kastaba ha ahaatee, cabbirka walxaha waaweyn iyo joogitaanka suurtagalka ah ee agglomerates waxay keeni karaan fuuq-celin gaabis ah iyo kala firdhinta dareeraha qodista ee ku salaysan biyaha, taas oo saameyn ku yeelan karta waxqabadka xakamaynta luminta dareeraha, gaar ahaan xaaladaha heerkulka sare iyo cadaadiska sare.
2. Habka Dheecaanka:
   • Habka Wax Soo Saarka: Habka wax soo saarka, cellulose-ka marka hore waxaa lagu kala firdhiyaa biyaha si uu u sameeyo wax soo saar, kaas oo markaa lagu falgalo sodium hydroxide iyo chloroacetic acid si uu si toos ah ugu soo saaro PAC xalka.
   • Cabbirka Walxaha: PAC-ga ay soo saarto habka slurry-ku wuxuu caadi ahaan leeyahay cabbir yar oo walax ah, waana mid si isku mid ah ugu kala firirsan xalka marka loo eego PAC-ga ay soo saarto habka cajiinka.
   • Iska caabbinta Lumista Dareeraha: PAC oo ay soo saarto habka slurry waxay u egtahay inay muujiso iska caabbinta luminta dareeraha ee dareeraha qodista. Cabbirka walxaha yar iyo kala firdhinta isku midka ah waxay keenaan fuuq-bax iyo kala firdhis degdeg ah oo ku yimaada dareeraha qodista ee ku salaysan biyaha, taasoo horseedaysa waxqabadka xakamaynta luminta dareeraha oo la hagaajiyay, gaar ahaan xaaladaha qodista ee adag.

PAC oo ay soo saarto habka cajiinka iyo PAC oo ay soo saarto habka slurry-ka ayaa bixin kara iska caabin wax ku ool ah oo ku saabsan luminta dareeraha ee dareeraha qodista. Si kastaba ha ahaatee, PAC oo ay soo saarto habka slurry-ka ayaa laga yaabaa inay bixiso faa'iidooyin gaar ah, sida fuuq-baxa iyo kala-baxa degdega ah, taasoo horseedaysa waxqabadka xakamaynta luminta dareeraha oo la xoojiyay, gaar ahaan deegaannada qodista heerkulka sare iyo cadaadiska sare. Ugu dambeyntii, doorashada labadan hab ee wax soo saarka waxay ku xirnaan kartaa shuruudaha waxqabadka gaarka ah, tixgelinta kharashka, iyo arrimo kale oo khuseeya codsiga dareeraha qodista.
