Kuyerekeza kwa Fluid Loss Resistance Property ya Polyanionic cellulose Yopangidwa ndi Dough Process And Slurry Process

Polyanionic cellulose (PAC) ndi polima wosungunuka m'madzi wotengedwa ku cellulose ndipo amagwiritsidwa ntchito ngati chowonjezera chowongolera kutaya kwamadzimadzi pobowola zomwe zimagwiritsidwa ntchito pofufuza mafuta ndi gasi.Njira ziwiri zazikulu zopangira PAC ndi ndondomeko ya mtanda ndi ndondomeko ya slurry.Nayi kufananitsa kwa katundu wa PAC wopangidwa ndi njira ziwiri izi:

1. Njira ya Mtanda:
   • Njira Yopangira: Pakupanga mtanda, PAC imapangidwa pochita mapadi ndi alkali, monga sodium hydroxide, kupanga mtanda wamchere wa cellulose.Mkate uwu umakhudzidwa ndi chloroacetic acid kuti ayambitse magulu a carboxymethyl pamsana wa cellulose, zomwe zimapangitsa PAC.
   • Tinthu Kukula: PAC opangidwa ndi ndondomeko mtanda zambiri ali yokulirapo tinthu kukula ndipo mungakhale agglomerates kapena aggregates wa PAC particles.
   • Kukana Kutaya Kwamadzimadzi: PAC yopangidwa ndi mtanda nthawi zambiri imawonetsa kukana kwamadzimadzi mumadzi obowola.Komabe, zazikulu tinthu kukula ndi kuthekera kukhalapo kwa agglomerates zingachititse pang'onopang'ono hydration ndi kubalalitsidwa mu madzi pobowola madzi, zimene zingakhudze madzimadzi imfa kulamulira ntchito, makamaka mkulu-kutentha ndi mkulu-anzanu zinthu.
2. Njira ya Slurry:
   • Njira Yopangira: Mu slurry process, mapadi amayamba kumwazikana m'madzi kuti apange slurry, yomwe imachitidwa ndi sodium hydroxide ndi chloroacetic acid kuti ipange PAC mwachindunji mu yankho.
   • Tinthu Kukula: PAC opangidwa ndi slurry ndondomeko zambiri ali ang'onoang'ono tinthu kukula ndi uniformly omwazika mu njira poyerekeza PAC opangidwa ndi ndondomeko mtanda.
   • Fluid Loss Resistance: PAC yopangidwa ndi slurry process imakonda kuwonetsa kukana kwamadzimadzi m'madzi akubowola.The ang'onoang'ono tinthu kukula ndi yunifolomu kubalalitsidwa zimabweretsa mofulumira hydration ndi kubalalitsidwa mu madzi pobowola madzi, kutsogolera bwino madzimadzi kutaya kulamulira ntchito, makamaka zovuta pobowola zinthu.

onse PAC opangidwa ndi ndondomeko mtanda ndi PAC opangidwa ndi ndondomeko slurry angapereke ogwira madzimadzi imfa kukana mu pobowola madzi.Komabe, PAC yopangidwa ndi slurry process imatha kupereka zabwino zina, monga kuthamanga kwamadzi komanso kubalalitsidwa, zomwe zimatsogolera kuwongolera magwiridwe antchito amadzimadzi, makamaka pobowola kutentha kwambiri komanso kuthamanga kwambiri.Pamapeto pake, kusankha pakati pa njira ziwiri zopangira izi kungadalire zofunikira zinazake zogwirira ntchito, kutengera mtengo wake, ndi zinthu zina zogwirizana ndi kugwiritsa ntchito madzi obowola.
