Polyacrylamide CAS:9003-05-8

Polyacrylamide imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso m'magawo azachilengedwe, makamaka ngati flocculant mu njira zoyeretsera madzi ndi madzi otayira. Monga flocculating agent, imathandizira kusonkhanitsa tinthu tating'onoting'ono ndi ma colloid m'madzi, zomwe zimathandiza kuti tisiyane ndi madzi kudzera mu sedimentation kapena kusefa. Kapangidwe kameneka kamapangitsa kuti ikhale yofunika kwambiri poyeretsera madzi otayira m'matauni ndi m'mafakitale, komwe kumathandiza kuchotsa zodetsa, kufotokozera bwino madzi otayira, ndi kuchotsa madzi otayira, zomwe zimathandiza kuteteza chilengedwe ndi kusunga zinthu. Kuphatikiza apo, polyacrylamide imagwiritsidwa ntchito ngati chowonjezera kukhuthala ndi rheology mu ntchito zosiyanasiyana monga kukonza mchere, kupanga mapepala, ndi zinthu zosamalira munthu. Pokonza mchere, imagwira ntchito ngati flocculant ndi thickener kuti iwonjezere kukhazikika ndi kuchotsedwa kwa slurry ya mchere, kuthandizira kubwezeretsa ndi kukonza miyala ndi mchere wamtengo wapatali. Kuphatikiza apo, imagwira ntchito popanga inki zosindikizira, utoto, zomatira, ndi zodzoladzola, komwe imapereka kukhuthala ndi kukhazikika kwa mapangidwe, kuonetsetsa kuti zinthu zomaliza zikugwira ntchito bwino komanso mawonekedwe abwino. Mu gawo la kubwezeretsanso mafuta (EOR), polyacrylamide imagwiritsidwa ntchito ngati chowongolera kuyenda kuti iwonjezere kugwira ntchito bwino kwa kutulutsa mafuta m'mabotolo. Mwa kusintha mawonekedwe a madzi olowetsedwa kapena ma polymer, imathandizira kuchotsa ndikubwezeretsa mafuta owonjezera kuchokera pansi pa nthaka, zomwe zimathandiza kukonza bwino kupanga ma hydrocarbon ndi kasamalidwe ka malo osungiramo madzi. Kuphatikiza apo, imagwira ntchito ngati chochepetsa kukangana pa ntchito zophulika za hydraulic, zomwe zimathandiza kupopera bwino ma proppants ndi madzi m'zitsime zamafuta ndi gasi, kuthandizira chitukuko cha mphamvu zosazolowereka. Kuphatikiza apo, polyacrylamide imagwiritsidwa ntchito poletsa nthaka ndi kugwiritsa ntchito njira zowongolera kukokoloka kuti ichepetse kukokoloka kwa nthaka, kukonza kapangidwe ka nthaka, ndikuwonjezera kusunga madzi mu ntchito zaulimi ndi zomangamanga. Kutha kwake kumangirira tinthu ta nthaka, kuchepetsa kuyenda kwa madzi pamwamba, ndikulimbikitsa kukula kwa zomera kumathandizira njira zoyendetsera nthaka zokhazikika komanso chitukuko cha zomangamanga. Kuphatikiza apo, imagwiritsa ntchito popanga ma polima opangidwa ndi polyacrylamide omwe amayamwa kwambiri pa ntchito zaulimi, zaulimi, ndi zinthu zogulira, komwe kumathandiza kusunga madzi bwino komanso kasamalidwe ka chinyezi m'nthaka, matewera, ndi zinthu zaukhondo. Mwachidule, polyacrylamide ndi polima yogwira ntchito zambiri yomwe imagwiritsidwa ntchito ngati flocculant, thickener, rheology modifier, komanso stabilizer m'mafakitale monga kuyeretsa madzi, migodi, kubwezeretsa mafuta, ulimi, ndi chisamaliro chaumwini. Zopereka zake pakukonzanso chilengedwe, kubwezeretsa zinthu, ndi magwiridwe antchito azinthu zikuwonetsa kufunika kwake pothana ndi mavuto osiyanasiyana ndikuwonjezera magwiridwe antchito ndi kukhazikika kwa njira ndi zinthu zosiyanasiyana.
