Rashin fahimta da aka saba gani yayin zabar PAM

Polyacrylamide(PAM), a matsayin wani nau'in polymer flocculant da aka saba amfani da shi, ana amfani da shi sosai a cikin yanayi daban-daban na kula da najasa. Duk da haka, masu amfani da yawa sun faɗa cikin wasu rashin fahimta yayin zaɓin da amfani. Wannan labarin yana da nufin bayyana waɗannan rashin fahimta da kuma ba da fahimta da shawarwari daidai.

Rashin Fahimta 1: Girman nauyin kwayoyin halitta, haka ingancin flocculation yake ƙaruwa.

Lokacin zabar polyacrylamide, mutane da yawa suna tunanin cewa samfurin da ke da babban nauyin kwayoyin halitta dole ne ya sami ingantaccen flocculation. Amma a zahiri, akwai ɗaruruwan samfuran polyacrylamide, waɗanda suka dace da yanayi daban-daban na ingancin ruwa. Yanayin ruwan sharar da masana'antu ke samarwa a masana'antu daban-daban ya bambanta. Ƙimar pH da takamaiman ƙazanta na halaye daban-daban na ruwa sun bambanta sosai. Suna iya zama acidic, alkaline, tsaka tsaki, ko kuma suna ɗauke da mai, abu na halitta, launi, laka, da sauransu. Saboda haka, yana da wuya ga nau'in polyacrylamide guda ɗaya ya cika duk buƙatun maganin ruwan sharar gida. Hanya madaidaiciya ita ce da farko a zaɓi samfurin ta hanyar gwaje-gwaje, sannan a gudanar da gwaje-gwajen injina don tantance mafi kyawun adadin don cimma sakamako mafi inganci.

Rashin Fahimta na 2: Mafi girman yawan daidaitawa, mafi kyau

Lokacin shirya mafita na polyacrylamide, masu amfani da yawa suna ganin cewa yawan maida hankali, haka nan kuma ingancin flocculation zai fi kyau. Duk da haka, wannan ra'ayi ba daidai ba ne. A gaskiya ma, ya kamata a tantance yawan daidaitawar PAM bisa ga takamaiman yanayin najasa da laka. Gabaɗaya, mafita na PAM tare da yawan maida hankali na 0.1%-0.3% sun dace da flocculation da sedimentation, yayin da yawan da ake samu don dehydration na laka na birni da masana'antu shine 0.2%-0.5%. Idan akwai datti da yawa a cikin najasa, yawan PAM na iya buƙatar a ƙara yadda ya kamata. Saboda haka, ya kamata a tantance yawan daidaitawa mai ma'ana ta hanyar gwaje-gwaje kafin amfani don tabbatar da mafi kyawun tasirin amfani.

Rashin Fahimta 3: Tsawon lokacin narkewa da juyawa, mafi kyau

Polyacrylamide wani farin ƙwayar crystalline ne wanda ke buƙatar a narkar da shi gaba ɗaya don cimma mafi kyawun sakamako. Mutane da yawa suna tunanin cewa tsawon lokacin narkewa da juyawa ya fi kyau, amma a zahiri ba haka lamarin yake ba. Idan lokacin juyawa ya yi tsayi sosai, zai haifar da fashewar wani ɓangare na sarkar kwayoyin PAM kuma yana shafar aikin flocculation. Gabaɗaya, lokacin narkewa da juyawa bai kamata ya zama ƙasa da mintuna 30 ba kuma ya kamata a tsawaita shi yadda ya kamata lokacin da zafin jiki ya yi ƙasa a lokacin hunturu. Idan lokacin narkewa da juyawa ya yi gajere, PAM ba zai narke gaba ɗaya ba, wanda zai haifar da rashin iya yin flocculation cikin sauri a cikin najasa. Saboda haka, masu amfani ya kamata su tabbatar da isasshen lokacin narkewa da juyawa lokacin amfani da shi don tabbatar da tasirin flocculation na PAM.

Rashin Fahimta 4: Digirin Ionic/Ionic shine kawai tushen zaɓi

A matsayin ɗaya daga cikin muhimman alamomin polyacrylamide, ionicity yana nufin cajin ionic mara kyau da mai kyau da kuma yawan cajinsa. Mutane da yawa suna mai da hankali sosai ga ionicity lokacin siye, suna tunanin cewa mafi girma shine mafi kyau. Amma a zahiri, matakin ionicity yana da alaƙa da girman nauyin kwayoyin halitta. Mafi girman ionicity, ƙaramin nauyin kwayoyin halitta, da kuma mafi girman farashi. A cikin tsarin zaɓi, ban da ionicity, akwai buƙatar a yi la'akari da wasu abubuwa, kamar takamaiman yanayin ingancin ruwa, buƙatun tasirin flocculation, da sauransu. Saboda haka, ba za a iya zaɓar samfurin bisa ga matakin ionization kawai ba. Ana buƙatar ƙarin gwaji don tantance samfurin da ake buƙata.

A matsayinmai flocculant, polyacrylamide yana taka muhimmiyar rawa a masana'antar tace ruwa. Idan kana buƙatar zaɓar takamaiman bayanai da suka dace da kai, da fatan za a tuntuɓe ni.
