Ngwa nke Polyacrylamide

Polyacrylamide (PAM)bụ polymer mmiri na-agbaze mmiri na linear, bụ otu n'ime ihe ndị a na-ejikarị eme ihe na-eme ka mmiri na-edozi mmiri, PAM na ihe ndị na-emepụta ya nwere ike iji mee ihe dị ka ihe na-arụ ọrụ nke ọma na flocculant, thickener, onye na-ewusi akwụkwọ ike na onye na-eme ka mmiri na-adọkpụ.
