Momwe mungadziwire mtundu wa polyacrylamide

Monga tonse tikudziwa, mitundu yosiyanasiyana ya polyacrylamide ili ndi mitundu yosiyanasiyana ya mankhwala ochotsa zinyalala komanso zotsatira zake zosiyanasiyana. Kotero polyacrylamide ndi tinthu toyera tomwe timapangidwa, kodi tingasiyanitse bwanji chitsanzo chake?

Pali njira zinayi zosavuta zosiyanitsira chitsanzo cha polyacrylamide:

1. Tonse tikudziwa kuti cationic polyacrylamide ndiyo yokwera mtengo kwambiri pamsika, kutsatiridwa ndi non-ionic polyacrylamide, ndipo potsiriza anionic polyacrylamide. Kuchokera pamtengo, titha kupanga chigamulo choyambirira pa mtundu wa ion.

2. Sungunulani polyacrylamide kuti muyese pH ya yankho. pH yofanana ya mitundu yosiyanasiyana ndi yosiyana.

3. Choyamba, sankhani mankhwala a anionic polyacrylamide ndi cationic polyacrylamide, ndipo muwasungunule padera. Sakanizani yankho la mankhwala a polyacrylamide kuti muyesedwe ndi mayankho awiri a PAM. Ngati lichita ndi mankhwala a anionic polyacrylamide, zikutanthauza kuti Polyacrylamide ndi cationic. Ngati lichita ndi ma cations, zimatsimikizira kuti mankhwala a PAM ndi anionic kapena non-ionic. Vuto la njira iyi ndilakuti silingathe kuzindikira molondola ngati mankhwalawa ndi anionic kapena non-ionic polyacrylamide. Koma titha kuweruza kuchokera nthawi yawo yosungunuka, ma anion amasungunuka mwachangu kwambiri kuposa ma non-ion. Nthawi zambiri, anion imasungunuka kwathunthu mu ola limodzi, pomwe non-ion imatenga ola limodzi ndi theka.

4. Poganizira za kuyesa kwa zimbudzi, tonse tikudziwa kuti polyacrylamide cationic polyacrylamide PAM ndi yoyenera zinthu zoyimitsidwa zomwe zili ndi zinthu zachilengedwe zomwe zili ndi mphamvu yoipa; anionic PAM ndi yoyenera zinthu zoyimitsidwa zomwe zili ndi mphamvu yoipa komanso tinthu toyimitsidwa tomwe tili ndi mphamvu yoipa (0.01-1mm), pH ndi yosasunthika kapena ya alkaline; non-ionic polyacrylamide PAM ndi yoyenera kulekanitsa zinthu zolimba zomwe zili ndi mphamvu yoipa zomwe zili ndi mphamvu yoipa komanso yosauka, ndipo yankho lake ndi acidic kapena losalowerera. Ma floc opangidwa ndi cationic polyacrylamide ndi akuluakulu komanso okhuthala, pomwe ma floc opangidwa ndi anion ndi osakhala ion ndi ang'onoang'ono komanso omwazikana.
