Kuchuluka kwa kasinthidwe ka ntchito za anionic polyacrylamide

Anionic polyacrylamide imagwiritsidwa ntchito makamaka polimbitsa kusuntha kwa zinyalala, ili ndi mawonekedwe a polymer electrolyte m'malo osalowerera komanso amchere, imakhudzidwa ndi ma electrolyte amchere, ndipo ma ayoni achitsulo okwera mtengo amatha kulumikizidwa kukhala gel yosasungunuka, yomwe imagwiritsidwa ntchito kwambiri popanga madzi apakhomo, kukonza zinyalala zamafakitale ndi m'mizinda, komanso ingagwiritsidwenso ntchito pochotsa madzi m'madzi osapangidwa ndi zinthu zachilengedwe.

Madera atatu akuluakulu ogwiritsira ntchito anionic polyacrylamide:

Mu makampani opanga zinthu zopangira zitsulo, imagwiritsidwa ntchito poyeretsa madzi ochapira mpweya mu uvuni wotseguka, kuyeretsa madzi otayira m'mafakitale opangira zitsulo za ufa ndi mafakitale ophikira, kuyeretsa ma electrolyte ndi kuyeretsa madzi otayira a electroplating.

Mu migodi, imagwiritsidwa ntchito poyeretsa madzi ochapira ndi kuyandama kwa makala, kusefa kwa malasha oyera, kutaya madzi m'thupi (slag), kuyeretsa madzi m'thupi, kukhuthala ndi kusefa, kusungunuka kwa potaziyamu alkali ndi madzi osungunuka, kuyeretsa madzi m'thupi pogwiritsa ntchito fluorite ndi barite, kuyeretsa madzi amchere osaphika kuti agwiritsidwe ntchito pokonza mchere, kuyeretsa madzi m'thupi pogwiritsa ntchito matope ndi kuyeretsa madzi m'migodi ya phosphate.

Mu ntchito yokonza madzi otayira m'mizinda ndi m'mafakitale, imagwiritsidwa ntchito pokonza kuchotsa zinthu zolimba zoyimitsidwa, BOD ndi phosphate m'madzi otayira. Powonjezera 0.25mg/L hydrolyzed polyacrylamide ku thanki yoyamba ya madzi otayira, kuchuluka kwa zinthu zoyimitsidwa ndi BOD kumatha kuwonjezeka kufika pa 66% ndi 23%, motsatana. Powonjezera 0.3mg/L anionic polyacrylamide ku thanki yachiwiri ya madzi otayira, kuchuluka kwa zinthu zoyimitsidwa ndi BOD kumatha kuwonjezeka kufika pa 87% ndi 91%, motsatana, ndipo mphamvu yochotsa phosphorous imatha kuwonjezeka kuchoka pa 35% mpaka 91%. Pokonza madzi akumwa ndi madzi otayira m'nyumba, imagwiritsidwa ntchito pokonza pamwamba, kuwunikira madzi otayira komanso kusintha kwa filtrate.

Kusungunuka kwa kukonzekera kwa anionic polyacrylamide kumayambitsidwa:

1, yomwe imagwiritsidwa ntchito pokhazikitsa zimbudzi, chiŵerengero chovomerezeka cha 0.1%

2, choyamba thirani ufawo mofanana m'madzi apampopi, ndikusakaniza pa liwiro lapakati la 40-60 RPM kuti polima isungunuke bwino m'madzi isanawonjezedwe.

3, Pa nthawi yoyesera, tengani madzi otayira 100ml, onjezerani 10% ya polyacrylamide solution, ndikusakaniza pang'onopang'ono, gwiritsani ntchito syringe kuti muwonjezere pang'onopang'ono solution ya PAM, 0.5ml nthawi iliyonse, malinga ndi kukula kwa duwa la alum lomwe lapangidwa komanso kuyandikira kwa flocculant, kumveka bwino kwa supernitant, kuchuluka kwa sedimentation, mlingo kuti mudziwe mankhwala oyenera.
