1. Bayanin Samfurin
Gajartawar Polyacrylamide (amide)
polyacrylamide (PAM)
Tsabtataccen farin barbashi
Polyacrylamide, wanda ake magana da shi azaman PAM, an raba shi zuwa anionic (APAM), cationic (CPAM), da nonionic (NPAM). Polymer mai layi ne kuma ɗaya daga cikin nau'ikan mahaɗan polymer mai narkewa da aka fi amfani da shi. Polyacrylamide da abubuwan da suka samo asali za a iya amfani da su azaman flocculants masu inganci, masu kauri, masu haɓaka takarda da abubuwan rage jan ruwa, da sauransu, kuma ana amfani da su sosai a cikin jiyya na ruwa, yin takarda, man fetur, kwal, ma'adinai da ƙarfe, geology, yadi, gini, da sauransu. bangaren masana'antu.

3. Kariya don zaɓar samfuran polyacrylamide:
① Zaɓin flocculant yana ɗaukar cikakken la'akari da tsari da buƙatun kayan aiki.

② Ana iya ƙara ƙarfin floc ta hanyar ƙara nauyin kwayoyin halitta na flocculant.

③ Ana duba ƙimar cajin flocculant ta gwaji.

④ Canjin yanayi (zazzabi) yana rinjayar zaɓin flocculant.

⑤ Zaɓi nauyin kwayoyin halitta na flocculant bisa ga girman floc da ake buƙata ta hanyar jiyya.

⑥ Mix da flocculant da sludge sosai kafin magani.
