Nkuko twese tubizi, ubwoko butandukanye bwa polyacrylamide bufite ubwoko butandukanye bwo gutunganya imyanda n'ingaruka zitandukanye. None se polyacrylamide ni uduce tw'umweru twose, ni gute watandukanya icyitegererezo cyayo?
Hari uburyo 4 bworoshye bwo gutandukanya icyitegererezo cya polyacrylamide:
1. Twese tuzi ko polyacrylamide ya cationic ari yo ihenze cyane ku isoko, ikurikirwa na polyacrylamide itari ionic, hanyuma polyacrylamide ya anionic. Dukurikije igiciro, dushobora gufata umwanzuro w'ibanze ku bwoko bwa iyoni.
2. Shyira polyacrylamide kugira ngo upime agaciro ka pH k'umuti. Agaciro ka pH gahuye n'aka moderi zitandukanye karatandukanye.
3. Ubwa mbere, hitamo anionic polyacrylamide na cationic polyacrylamide products, hanyuma ubishongeshe ukwabyo. Vanga umuti wa polyacrylamide ugomba kugeragezwa hamwe na PAM solutions ebyiri. Iyo ihuye na anionic polyacrylamide product, bivuze ko Polyacrylamide ari cationic. Iyo ihuye na cations, bigaragaza ko PAM product ari anionic cyangwa non-ionic. Imbogamizi y'ubu buryo ni uko idashobora kumenya neza niba uwo muti ari anionic cyangwa non-ionic polyacrylamide. Ariko dushobora gucira urubanza igihe cyo gushonga kwawo, anions zirashonga vuba cyane kurusha non-ions. Muri rusange, anion ishongeshwa burundu mu isaha imwe, mu gihe non-ions bifata isaha imwe n'igice.
4. Dukurikije ubushakashatsi bw’imyanda, twese tuzi ko polyacrylamide cationic polyacrylamide PAM rusange ikwiriye ibintu bihagaze bifite amashanyarazi mabi birimo ibintu organic; anionic PAM ikwiriye ibintu bihagaze bifite amashanyarazi menshi hamwe n’uduce duhagaze. Ifite agaciro kanini (0.01-1mm), pH ni ntoya cyangwa irashonga; non-ionic polyacrylamide PAM ikwiriye gutandukanya ibintu bihagaze mu buryo buvanze na organic na inorganic, kandi umuti ni aside cyangwa neutral. Flocs zikozwe na cationic polyacrylamide ni nini kandi zibyimbye, mu gihe flocs zikozwe na anion na non-ion ari nto kandi zitatanye.
