Polyacrylamide
Polyacrylamide bụ polyarị dị n'ahịrị, a na-ekewa ngwaahịa ahụ n'ime ntụ ntụ na colloidal abụọ. Dika onu ogugu onu ogugu ya si di, enwere ike kee ya n'ime ihe omimi di ala (<1 million), medium molekụla arọ (2 ~ 4 million) na akwa molekụla dị elu (> .7 million). - ionic, anion na cationic. Mbibi mmiri (HPAM) nke ụdị anion. Ogwe osisi polyacrylamide bụ isi nwere ọtụtụ amide dị iche iche, yana ọrụ kemịkal dị elu, enwere ike gbanwee iji mepụta ọtụtụ ihe eji emepụta polyacrylamide. Ngwaahịa a n'ọtụtụ ebe e ji papermaking, ịnweta nhazi, mmanụ mmịpụta, nkà mmụta banyere ígwè, ụlọ ihe, nsị ọgwụgwọ na ndị ọzọ ọrụ.
