Ta yaya zan zabi nau'in Polyacrylamide?

Polyacrylamide(PAM) yawanci ana iya rarraba su zuwa anionic, cationic, da nonionic bisa ga nau'in ion. An fi amfani dashi don flocculation a cikin maganin ruwa. Lokacin zabar, nau'ikan ruwan sha na iya zaɓar nau'ikan daban-daban. Kuna buƙatar zaɓar PAM daidai gwargwadon halayen najasar ku. A lokaci guda, ya kamata ka kuma bayyana a cikin wane tsari za a ƙara polyacrylamide da manufar da kake son cimma ta amfani da shi.

Alamomin fasaha na polyacrylamide gabaɗaya sun haɗa da nauyin kwayoyin halitta, matakin hydrolysis, ionicity, danko, abun ciki na monomer saura, da sauransu. Ya kamata a fayyace waɗannan alamomi bisa ga ruwan sharar gida da kuke jiyya.

1. Nauyin kwayoyin halitta / danko

Polyacrylamide yana da nau'ikan nau'ikan nau'ikan kwayoyin halitta, daga ƙasa zuwa babba. Nauyin kwayoyin halitta yana rinjayar aikin polymers a aikace-aikace daban-daban. Babban nauyin kwayoyin polyacrylamide yawanci ya fi tasiri a cikin tsarin flocculation saboda sarƙoƙin polymer ɗin su ya fi tsayi kuma yana iya haɗa ƙarin barbashi tare.

Dankowar PAM bayani yana da girma sosai. Lokacin da ionization ya tsaya tsayin daka, girman nauyin kwayoyin halitta na polyacrylamide, mafi girman danko na maganin sa. Wannan shi ne saboda sarkar macromolecular na polyacrylamide yana da tsayi da bakin ciki, kuma juriya ga motsi a cikin maganin yana da girma sosai.

2. Digiri na hydrolysis da ionity

Ionicity na PAM yana da tasiri mai girma akan tasirin amfani da shi, amma ƙimar da ta dace ta dogara da nau'in da yanayin kayan da aka bi da su, kuma akwai kyawawan dabi'u daban-daban a cikin yanayi daban-daban. Lokacin da ƙarfin ionic na kayan da aka bi da shi ya yi girma (mafi yawan kwayoyin halitta), ionity na PAM da aka yi amfani da shi ya kamata ya zama mafi girma, in ba haka ba ya zama ƙasa. Gabaɗaya, ana kiran matakin anion digiri na hydrolysis, kuma matakin ion gabaɗaya ana kiransa matakin cation.

Yadda za a zabi polyacrylamideya dogara da yawan adadin colloid da kuma dakatar da daskararru a cikin ruwa. Bayan fahimtar alamun da ke sama, yadda za a zabi PAM mai dacewa?

1. Fahimtar tushen najasa

Na farko, dole ne mu fahimci tushen, yanayi, abun da ke ciki, m abun ciki, da dai sauransu na sludge.

Gabaɗaya magana, cationic polyacrylamide ana amfani da shi don magance sludge na halitta, kuma ana amfani da polyacrylamide anionic don magance sludge na inorganic. Lokacin da pH yayi girma, bai kamata a yi amfani da polyacrylamide na cationic ba, kuma lokacin da , bai kamata a yi amfani da polyacrylamide anionic ba. Ƙarfin acidity ya sa bai dace da amfani da anionic polyacrylamide ba. Lokacin da ingantaccen abun ciki na sludge ya yi girma, adadin polyacrylamide da aka yi amfani da shi yana da girma.

2. Zaɓin ionity

Don sludge wanda ke buƙatar bushewa a cikin maganin najasa, zaka iya zaɓar flocculants tare da ionity daban-daban ta hanyar ƙananan gwaje-gwaje don zaɓar polyacrylamide mafi dacewa, wanda zai iya cimma sakamako mafi kyau na flocculation kuma rage girman sashi, adana farashi.

3. Zaɓin nauyin kwayoyin halitta

Gabaɗaya magana, mafi girman nauyin kwayoyin halitta na samfuran polyacrylamide, mafi girman danko, amma a cikin amfani, mafi girman nauyin kwayoyin halitta na samfurin, mafi kyawun tasirin amfani. A cikin takamaiman amfani, yakamata a ƙayyade nauyin kwayoyin da ya dace na polyacrylamide bisa ga ainihin masana'antar aikace-aikacen, ingancin ruwa da kayan aikin jiyya.

Lokacin da kuka saya da amfani da PAM a karon farko, ana bada shawarar samar da takamaiman yanayin najasa zuwa masana'antar flocculant, kuma za mu ba da shawarar nau'in samfurin da ya dace da ku. Da samfuran wasiku don gwaji. Idan kuna da ƙwarewa da yawa a cikin maganin najasar ku, zaku iya gaya mana takamaiman buƙatun ku, filayen aikace-aikacen, da matakai, ko kuma ba mu samfuran PAM kai tsaye da kuke amfani da su a halin yanzu, kuma za mu daidaita ku tare da madaidaiciyar polyacrylamide.
