Polyacrylamide(PAM) yawanci ana iya rarraba shi zuwa anionic, cationic, da nonionic bisa ga nau'in ion. Ana amfani da shi galibi don flocculation a cikin maganin ruwa. Lokacin zabar, nau'ikan ruwan shara daban-daban na iya zaɓar nau'ikan daban-daban. Kuna buƙatar zaɓar PAM da ya dace bisa ga halayen najasar ku. A lokaci guda, ya kamata ku kuma fayyace a cikin wane tsari za a ƙara polyacrylamide da kuma manufar da kuke son cimmawa ta amfani da shi.
Alamomin fasaha na polyacrylamide gabaɗaya sun haɗa da nauyin kwayoyin halitta, matakin hydrolysis, ionicity, viscosity, ragowar monomer, da sauransu. Ya kamata a fayyace waɗannan alamun gwargwadon ruwan sharar da kuke shafawa.
1. Nauyin kwayoyin halitta/danko
Polyacrylamide yana da nau'ikan nauyin kwayoyin halitta iri-iri, daga ƙasa zuwa babba sosai. Nauyin kwayoyin halitta yana shafar aikin polymers a aikace-aikace daban-daban. Polyacrylamide mai nauyin kwayoyin halitta yawanci yana da tasiri sosai a tsarin flocculation saboda sarƙoƙin polymer ɗinsu sun fi tsayi kuma suna iya haɗa ƙarin ƙwayoyin cuta tare.
Dankowar maganin PAM yana da yawa sosai. Idan ionization ya tabbata, girman nauyin kwayoyin polyacrylamide, girman dankowar maganinsa. Wannan saboda sarkar macromolecular na polyacrylamide yana da tsayi kuma siriri, kuma juriya ga motsi a cikin maganin yana da girma sosai.
2. Matakin hydrolysis da ionicity
Ionicity na PAM yana da tasiri sosai kan tasirin amfaninsa, amma ƙimar da ta dace ta dogara ne akan nau'in da yanayin kayan da aka yi wa magani, kuma akwai ƙima daban-daban mafi kyau a yanayi daban-daban. Idan ƙarfin ionic na kayan da aka yi wa magani ya yi yawa (mafi ƙarancin abu mara tsari), ionicity na PAM da aka yi amfani da shi ya kamata ya zama mafi girma, in ba haka ba ya kamata ya zama ƙasa. Gabaɗaya, ana kiran matakin anion matakin hydrolysis, kuma matakin ion gabaɗaya ana kiransa matakin cation.
Yadda ake zaɓar polyacrylamideya dogara da yawan sinadarin colloid da daskararru da aka dakatar a cikin ruwa. Bayan fahimtar alamomin da ke sama, ta yaya za a zaɓi PAM mai dacewa?
1. Fahimci tushen najasa
Da farko, dole ne mu fahimci tushen, yanayi, abun da ke ciki, abubuwan da ke cikin taki, da sauransu.
Gabaɗaya dai, ana amfani da cationic polyacrylamide don magance gurɓataccen ruwa, kuma ana amfani da anionic polyacrylamide don magance gurɓataccen ruwa. Idan pH ya yi yawa, bai kamata a yi amfani da cationic polyacrylamide ba, kuma idan , anionic polyacrylamide bai kamata a yi amfani da shi ba. Ƙarfin acidity yana sa bai dace a yi amfani da anionic polyacrylamide ba. Idan gurɓataccen ruwa ya yi yawa, adadin polyacrylamide da ake amfani da shi yana da yawa.
2. Zaɓin ionicity
Ga laka da ke buƙatar bushewa a cikin maganin najasa, zaku iya zaɓar flocculants tare da ionicity daban-daban ta hanyar ƙananan gwaje-gwaje don zaɓar polyacrylamide mafi dacewa, wanda zai iya cimma mafi kyawun tasirin flocculation da rage yawan amfani, yana adana kuɗi.
3. Zaɓin nauyin kwayoyin halitta
Gabaɗaya dai, girman nauyin ƙwayoyin halitta na samfuran polyacrylamide, girman ɗanɗano, amma a lokacin amfani, girman nauyin ƙwayoyin halitta na samfurin, mafi kyawun tasirin amfani. A takamaiman amfani, ya kamata a ƙayyade nauyin ƙwayoyin halitta da ya dace na polyacrylamide bisa ga ainihin masana'antar aikace-aikacen, ingancin ruwa da kayan aikin magani.
Idan ka saya kuma ka yi amfani da PAM a karon farko, ana ba da shawarar ka samar da takamaiman yanayin najasa ga masana'antar flocculant, kuma za mu ba ka shawarar nau'in samfurin da ya fi dacewa da kai. Kuma ka aika samfuran zuwa ga abokan ciniki don gwaji. Idan kana da ƙwarewa sosai a fannin kula da najasa, za ka iya gaya mana takamaiman buƙatunka, filayen aikace-aikacen, da hanyoyin aiki, ko kuma ka ba mu samfuran PAM da kake amfani da su kai tsaye, kuma za mu daidaita ka da polyacrylamide da ya dace.
