Kuyerekeza kwa Katundu Wotsutsana ndi Kutayika kwa Madzi a Polyanionic Cellulose Wopangidwa ndi Njira Yopangira Mtanda ndi Njira Yothira Madzi

Polyanionic cellulose (PAC) ndi polima wosungunuka m'madzi wochokera ku cellulose ndipo nthawi zambiri amagwiritsidwa ntchito ngati chowonjezera chowongolera kutayika kwa madzi m'madzi obowola omwe amagwiritsidwa ntchito pofufuza mafuta ndi gasi. Njira ziwiri zazikulu zopangira PAC ndi njira yopangira mtanda ndi njira yothira madzi. Nayi kufananiza kwa mphamvu ya PAC yolimbana ndi kutayika kwa madzi yomwe imapangidwa ndi njira ziwirizi:

1. Njira Yopangira Mtanda:
   • Njira Yopangira: Mu ndondomeko ya mtanda, PAC imapangidwa mwa kusakaniza cellulose ndi alkali, monga sodium hydroxide, kuti ipange mtanda wa alkaline cellulose. Kenako mtanda uwu umaphatikizidwa ndi chloroacetic acid kuti ubweretse magulu a carboxymethyl pa msana wa cellulose, zomwe zimapangitsa kuti PAC ipangidwe.
   • Kukula kwa Tinthu: PAC yopangidwa ndi njira ya mtanda nthawi zambiri imakhala ndi tinthu tating'onoting'ono tokulirapo ndipo imatha kukhala ndi tinthu tating'onoting'ono kapena tinthu tating'onoting'ono ta PAC.
   • Kukana Kutaya Madzi: PAC yopangidwa ndi njira ya mtanda nthawi zambiri imakhala ndi kukana bwino kutaya madzi m'madzi obowola. Komabe, kukula kwakukulu kwa tinthu tating'onoting'ono komanso kupezeka kwa ma agglomerate kungayambitse kuchepa kwa madzi ndi kufalikira pang'onopang'ono m'madzi obowola pogwiritsa ntchito madzi, zomwe zingakhudze momwe madzi amagwirira ntchito, makamaka m'malo otentha kwambiri komanso opanikizika kwambiri.
2. Njira Yothira Madzi:
   • Njira Yopangira: Mu ndondomeko ya slurry, cellulose imafalikira koyamba m'madzi kuti ipange slurry, yomwe kenako imayanjanitsidwa ndi sodium hydroxide ndi chloroacetic acid kuti ipange PAC mwachindunji mu yankho.
   • Kukula kwa Tinthu: PAC yopangidwa ndi njira yothira matope nthawi zambiri imakhala ndi tinthu tating'onoting'ono ndipo imafalikira mofanana mu yankho poyerekeza ndi PAC yopangidwa ndi njira yothira matope.
   • Kukana Kutayika kwa Madzi: PAC yopangidwa ndi njira yothira madzi nthawi zambiri imakhala ndi kukana bwino kutaya madzi m'madzi obowola. Kukula kochepa kwa tinthu tating'onoting'ono ndi kufalikira kofanana kumapangitsa kuti madzi azisungunuka mwachangu komanso kuti madzi azisungunuka m'madzi obowola, zomwe zimapangitsa kuti madzi azisungunuka bwino, makamaka m'mikhalidwe yovuta yobowola.

Ma PAC onse opangidwa ndi njira ya mtanda ndi ma PAC opangidwa ndi njira ya slurry angapereke mphamvu yothandiza yolimbana ndi kutaya madzi m'madzi obowola. Komabe, ma PAC opangidwa ndi njira ya slurry angapereke zabwino zina, monga kunyowa mwachangu ndi kufalikira, zomwe zimapangitsa kuti madzi aziyenda bwino, makamaka m'malo obowola otentha kwambiri komanso opanikizika kwambiri. Pomaliza, kusankha pakati pa njira ziwirizi zopangira kungadalire zofunikira pakuchita bwino, kuganizira za mtengo, ndi zina zokhudzana ndi kugwiritsa ntchito madzi obowola.
