Yadda za a ƙayyade wane nau'in polyacrylamide ne

Kamar yadda muka sani, nau'ikan polyacrylamide daban-daban suna da nau'ikan maganin najasa daban-daban da tasiri daban-daban. Don haka polyacrylamide duk farin barbashi ne, yadda za a bambanta samfurinsa?

Akwai hanyoyi guda 4 masu sauƙi don rarrabe samfurin polyacrylamide:

1. Dukanmu mun san cewa cationic polyacrylamide shine mafi tsada a kasuwa, sai kuma polyacrylamide maras ionic, sannan a karshe anionic polyacrylamide. Daga farashin, zamu iya yin hukunci na farko akan nau'in ion.

2. Narke polyacrylamide don auna ƙimar pH na maganin. Madaidaitan ƙimar pH na samfura daban-daban sun bambanta.

3. Na farko, zaɓi anionic polyacrylamide da cationic polyacrylamide kayayyakin, da kuma narkar da su dabam. Haɗa maganin polyacrylamide don gwadawa tare da hanyoyin PAM guda biyu. Idan ya amsa da samfurin anionic polyacrylamide, yana nufin cewa Polyacrylamide na cationic. Idan ya amsa tare da cations, yana tabbatar da cewa samfurin PAM anionic ne ko mara ion. Rashin lahani na wannan hanyar shine cewa ba zai iya tantance daidai ko samfurin anionic ko polyacrylamide maras ionic ba. Amma za mu iya yin hukunci daga rushewar lokaci, anions narke da sauri fiye da wadanda ba ions. Gabaɗaya, anion ɗin yana narkewa gaba ɗaya cikin sa'a ɗaya, yayin da rashin ion yana ɗaukar awa ɗaya da rabi.

4. An yi la'akari da gwaje-gwajen najasa, duk mun san cewa polyacrylamide cationic polyacrylamide PAM ya dace da abin da aka dakatar da shi mara kyau wanda ke dauke da kwayoyin halitta; anionic PAM ya dace da babban taro na ingantaccen abin da aka dakatar da abubuwan da aka dakatar da abubuwan da aka dakatar da abubuwan da aka dakatar da su (0.01-1mm), ƙimar pH tsaka tsaki ko alkaline mai narkewa; non-ionic polyacrylamide PAM ya dace da rabuwa da daskararru da aka dakatar a cikin yanayin gauraye na kwayoyin halitta da inorganic, kuma maganin shine acidic ko tsaka tsaki. Gilashin da aka kafa ta cationic polyacrylamide suna da girma kuma suna da yawa, yayin da flocs da aka kafa ta anion da wadanda ba ion ba ne kuma suna warwatse.
