Yadda ake ƙara PAM

Polyacrylamide (PAM) wani nau'in polymer ne na layi tare da flocculation, mannewa, raguwar ja, da sauran kaddarorin. Kamar yadda aPolymer Organic Flocculant, ana amfani da shi sosai a fannin kula da ruwa. Lokacin amfani da PAM, yakamata a bi ingantattun hanyoyin aiki don gujewa ɓarna na sinadarai.

Tsarin Ƙara PAM

DominPAM mai ƙarfi, yana buƙatar ƙarawa a cikin ruwa bayan an narkar da shi. Don halaye daban-daban na ruwa, ana buƙatar zaɓar nau'ikan PAM daban-daban, kuma an daidaita hanyoyin warware su cikin ƙima daban-daban. Lokacin ƙara polyacrylamide, ya kamata a kula da waɗannan abubuwan:

Gwaje-gwajen Jar:Ƙayyade mafi kyawun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙima ta hanyar gwajin kwalba. A cikin gwajin kwalba, a hankali ƙara yawan adadin polyacrylamide, lura da tasirin flocculation, kuma ƙayyade mafi kyawun sashi.

Ana Shiri PAM Aqueous Magani:Tun da anionic PAM (APAM) da nonionic PAM (NPAM) suna da nauyin kwayoyin mafi girma da ƙarfin ƙarfi, anionic polyacrylamide yawanci ana tsara shi a cikin wani bayani mai ruwa tare da maida hankali na 0.1% (yana nufin m abun ciki) da gishiri maras kyau, ruwa mai tsafta. Zabi enameled, galvanized aluminum, ko roboket robobi maimakon kwantena ƙarfe kamar yadda ions baƙin ƙarfe ke haifar da lalata sinadarai na duk PAM. A lokacin shirye-shiryen, polyacrylamide yana buƙatar a yayyafa shi daidai a cikin ruwa mai motsawa kuma a yi zafi sosai (<60 ° C) don hanzarta rushewa. Lokacin narkar da, ya kamata a biya hankali don ƙara samfurin daidai kuma a hankali a cikin narke tare da motsawa da matakan dumama don guje wa ƙarfafawa. Ya kamata a shirya maganin a cikin zafin jiki mai dacewa, kuma ya kamata a kauce masa tsawaita tsayi da tsayin daka mai tsanani. Ana ba da shawarar cewa mahaɗin yana juyawa a 60-200 rpm; in ba haka ba, zai haifar da lalata polymer kuma yana tasiri tasirin amfani.

Bukatun Dosing:Yi amfani da na'ura don ƙara PAM. A cikin matakin farko na amsawar ƙara PAM, yana da mahimmanci don ƙara yawan damar haɗuwa tsakanin sinadarai da ruwa don a bi da su kamar yadda zai yiwu, ƙara yawan motsawa, ko ƙara yawan yawan ruwa.

Abubuwan Lura Lokacin Ƙara PAM

Lokacin Rushewa:Nau'o'in PAM daban-daban suna da lokutan rushewa daban-daban. Cationic PAM yana da ɗan gajeren lokacin rushewa, yayin da anionic da nonionic PAM suna da tsawon lokacin rushewa. Zaɓin lokacin da ya dace na rushewa zai iya taimakawa inganta tasirin flocculation.

Sashi da Tattaunawa:Madaidaicin sashi shine mabuɗin don cimma mafi kyawun tasirin flocculation. Yawan allurai na iya haifar da coagulation mai yawa na colloid da ɓangarorin da aka dakatar, suna samar da manyan sediments maimakon flocs, don haka yana shafar ingancin magudanar ruwa.

Yanayin Cakuda:Don tabbatar da isasshen haɗawar PAM da ruwan sha, ana buƙatar zaɓin kayan aikin haɗawa da hanyoyin da suka dace. Cakuda mara daidaituwa na iya haifar da rashin cikar narkarwar PAM, ta haka yana shafar tasirin sa.

Yanayin Muhalli na Ruwa:Abubuwan muhalli kamar ƙimar pH, zafin jiki, matsa lamba, da sauransu, kuma za su shafi tasirin flocculation na PAM. Dangane da ingancin ruwan sharar gida, waɗannan sigogi na iya buƙatar daidaitawa don sakamako mafi kyau.

Jerin Dosing:A cikin tsarin samar da wakilai da yawa, yana da mahimmanci don fahimtar jerin adadin wakilai daban-daban. Jerin kashi mara kyau na iya rinjayar hulɗar tsakanin PAM da colloids da kuma ɓangarorin da aka dakatar, ta haka yana tasiri tasirin flocculation.

Polyacrylamide(PAM) wani nau'in polymer ne tare da aikace-aikace daban-daban, musamman a cikin maganin ruwa. Don haɓaka tasirin sa da kuma guje wa ɓarna, yana da mahimmanci a bi hanyoyin aiki da suka dace. Ta hanyar la'akari a hankali abubuwa kamar lokacin rushewa, sashi, yanayin haɗawa, yanayin muhallin ruwa, da tsarin sashi, zaku iya amfani da PAM yadda ya kamata don cimma sakamakon flocculation da ake so da haɓaka ingancin ruwa.
