Momwe mungadziwire mtundu wa polyacrylamide

Monga tonse tikudziwa, mitundu yosiyanasiyana ya polyacrylamide ili ndi mitundu yosiyanasiyana yachimbudzi komanso zotsatira zosiyanasiyana. Choncho polyacrylamide onse particles woyera, mmene kusiyanitsa chitsanzo chake?

Pali 4 njira zosavuta kusiyanitsa chitsanzo cha Polyacrylamide:

1. Tonse tikudziwa kuti cationic Polyacrylamide ndi yokwera mtengo kwambiri pamsika, yotsatiridwa ndi polyacrylamide yopanda ionic, ndipo potsiriza anionic polyacrylamide. Kuchokera pamtengo, titha kupanga chigamulo choyambirira pamtundu wa ion.

2. Sungunulani polyacrylamide kuyeza pH mtengo wa yankho. Mitundu yofananira ya pH yamitundu yosiyanasiyana ndi yosiyana.

3. Choyamba, sankhani anionic Polyacrylamide ndi cationic Polyacrylamide mankhwala, ndi kupasuka iwo mosiyana. Sakanizani mankhwala a polyacrylamide kuti muyesedwe ndi mayankho awiri a PAM. Ngati zimachitikira ndi anionic Polyacrylamide mankhwala, zikutanthauza kuti Polyacrylamide ndi cationic. Ngati imachita ndi ma cation, imatsimikizira kuti mankhwala a PAM ndi anionic kapena osakhala a ionic. Choyipa cha njirayi ndikuti sichingazindikire molondola ngati mankhwalawa ndi anionic kapena si-ionic polyacrylamide. Koma titha kuweruza kuyambira nthawi yawo yakuwonongeka, anions amasungunuka mwachangu kuposa ma-ion. Nthawi zambiri, anion imasungunuka kwathunthu mu ola limodzi, pamene osati ion imatenga ola limodzi ndi theka.

4. Kutengera ku kuyesa kwa zimbudzi, ife tonse tikudziwa kuti ambiri Polyacrylamide cationic Polyacrylamide PAM ndi oyenera zoipa mlandu inaimitsidwa nkhani munali zinthu organic; anionic PAM ndiyoyenera kuphatikizika kwapamwamba kwa zinthu zomwe zimayimitsidwa bwino komanso tinthu tating'onoting'ono ta Coarse (0.01-1mm), pH mtengo ndi ndale kapena zamchere sungunuka; non-ionic polyacrylamide PAM ndi oyenera kulekana kwa zolimba inaimitsidwa mu chikhalidwe osakaniza organic ndi inorganic, ndi njira ndi acidic kapena ndale. Ma flocs opangidwa ndi cationic polyacrylamide ndi akulu komanso owundana, pomwe ma flocs opangidwa ndi anion ndi osakhala ion ndi ang'onoang'ono komanso amwazikana.
