Polyacrylamide Molecular Water Treatment Chemicals

Polyacrylamide (PAM) ndi liwu loti acrylamide homopolymer kapena copolymerized ndi ma monomers ena, ndipo ndi amodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri ya ma polima osungunuka m'madzi.Chifukwa structural unit wa Polyacrylamide lili amide magulu, n'zosavuta kupanga haidrojeni nsinga, zimene zimapangitsa kukhala ndi madzi solubility wabwino ndi mkulu mankhwala ntchito, ndipo n'zosavuta kupeza zosintha zosiyanasiyana nthambi unyolo kapena maukonde dongosolo kudzera Ankalumikiza kapena crosslinking., Amagwiritsidwa ntchito kwambiri pofufuza mafuta a petroleum, mankhwala a madzi, nsalu, kupanga mapepala, mchere, mankhwala, ulimi ndi mafakitale ena, ndipo amadziwika kuti "othandizira mafakitale onse".minda waukulu ntchito m'mayiko akunja mankhwala madzi, papermaking, migodi, zitsulo, etc.;ku China, ndalama zazikuluzikuluzi zimagwiritsidwa ntchito pochotsa mafuta, ndipo minda yomwe ikukula mofulumira kwambiri ili m'madera opangira madzi ndi kupanga mapepala.

Malo oyeretsera madzi:

Kuyeretsa madzi kumaphatikizapo kuyeretsa madzi osaphika, kuyeretsa zimbudzi komanso kukonza madzi m'mafakitale.Kugwiritsidwa ntchito molumikizana ndi adamulowetsa mpweya mu yaiwisi madzi mankhwala, izo angagwiritsidwe ntchito coagulation ndi kulongosola za inaimitsidwa particles m'madzi apakhomo.Kugwiritsa ntchito organic flocculant acrylamide m'malo mwachilengedwe flocculant kuonjezera mphamvu kuyeretsa madzi ndi oposa 20% ngakhale popanda kusintha thanki yokhazikika;pochiza zimbudzi, ntchito Polyacrylamide akhoza kuonjezera mlingo magwiritsidwe ntchito yobwezeretsanso madzi ndipo angagwiritsidwenso ntchito ngati Sludge dewatering;amagwiritsidwa ntchito ngati gawo lofunikira pakupangira madzi m'mafakitale.The gawo lalikulu la ntchito Polyacrylamide kunja ndi mankhwala madzi, ndi ntchito imeneyi mu China akulimbikitsidwa.Udindo waukulu wa Polyacrylamide mu mankhwala madzi: [2]
(1) Kuchepetsa kuchuluka kwa flocculant.Pansi pa mfundo yokwaniritsa madzi omwewo, polyacrylamide imagwiritsidwa ntchito ngati coagulant coagulant kuphatikiza ndi flocculants ina, yomwe ingachepetse kwambiri kuchuluka kwa flocculant yomwe imagwiritsidwa ntchito;(2) Sinthani madzi kukhala abwino.Mu mankhwala akumwa madzi ndi mafakitale mankhwala zinyalala, ntchito Polyacrylamide osakaniza flocculants inorganic akhoza kwambiri kusintha madzi;(3) Wonjezerani mphamvu ya floc ndi kuthamanga kwa sedimentation.The flocs opangidwa ndi Polyacrylamide ndi mkulu mphamvu ndi zabwino sedimentation ntchito, potero kuonjezera olimba-zamadzimadzi kulekana liwiro ndi kutsogolera sludge kuchepa madzi m`thupi;(4) Anti-corrosion ndi anti-scaling ya kuzungulira kuzirala dongosolo.Ntchito Polyacrylamide akhoza kwambiri kuchepetsa kuchuluka kwa flocculants zochita kupanga, potero kupewa mafunsidwe a zinthu zachilengedwe padziko zida ndi kuchepetsa dzimbiri ndi makulitsidwe zida.

Polyacrylamide chimagwiritsidwa ntchito monga thandizo posungira, fyuluta thandizo, mlingo wothandizila, etc. m'munda papermaking kusintha khalidwe pepala, slurry kuchepa madzi m'thupi ntchito, posungira mlingo wa ulusi wabwino ndi fillers, kuchepetsa kumwa zopangira ndi kuipitsa chilengedwe, Ntchito ngati dispersant kuti onjezerani kufanana kwa pepala.Polyacrylamide zimagwiritsa ntchito mbali ziwiri mu makampani pepala.Chimodzi ndikuwonjezera kuchuluka kwa kusungirako zodzaza ndi utoto kuti muchepetse kutayika kwa zinthu zopangira ndi kuwononga chilengedwe;china ndi kuonjezera mphamvu ya pepala.Kuwonjezera polyacrylamide kwa zinthu pepala akhoza kuonjezera mlingo posungira ulusi wabwino ndi filler particles pa ukonde ndi imathandizira kuchepa madzi m'thupi la zinthu pepala.Limagwirira wa zochita za polyacrylamide ndi kuti particles mu slurry ndi flocculated ndi anakhalabe pa fyuluta nsalu ndi neutralization kapena bridging.Mapangidwe a flocs amathanso kupangitsa kuti madzi mu slurry azisefa mosavuta, kuchepetsa kutayika kwa ulusi m'madzi oyera, kuchepetsa kuipitsidwa kwa chilengedwe, komanso kuthandizira kukonza bwino kwa zida zosefera ndi matope.
