Na-ekesa, flocculant
Ihe na-ekesa polyacrylamide na ụlọ ọrụ akwụkwọ bụ tumadi cationic polyacrylamide nke nwere ịdị arọ molekụla dị obere.N'ihi na yinye molekụla ya nwere otu carboxyl, ọ na-enwe mmetụta na-agbasasị na eriri ndị ebubo na-adịghị mma, nwere ike ịbawanye viscosity nke pulp, na-eme ka nkwusioru eriri, ma nwee ike ịrụ ọrụ nke ọma. dispersant maka ogologo eriri.A na-eji amphoteric polyacrylamide mee ihe dị ka flocculant maka ọgwụgwọ mmiri na ụlọ ọrụ akwụkwọ.Otu amide ya nwere ike ịmepụta njikọ nke hydrogen na ọtụtụ ihe dị na mmiri mkpofu, ya mere ọ nwere ike gbasaa ihe ndị ahụ gbasasịrị n'ime mmiri ọnụ na agglomerate ha.Na-enyere aka idozi na nzacha nke ụmụ irighiri ihe.Tụnyere ndị ọzọ inorganic flocculants, amphoteric polyacrylamide nwere uru nke zuru ezu iche iche, obere oriri na mmepụta, ngwa ngwa edozi ọsọ, obere mmepụta sludge, na mfe post-ọgwụgwọ, wdg, nke nwere ike izute chọrọ dị iche iche ọgwụgwọ mmiri mkpofu.
N'ịchịkọta, polyacrylamide na-arụ ọrụ dị mkpa na ụlọ ọrụ akwụkwọ.Enwere ike iji ya mee ihe dị ka onye na-edozi akwụkwọ, onye na-ewusi ike, onye na-ekesa, enyemaka nzacha, wdg.

A na-eji CPAM mee ihe dị ka onye na-agba ume, site na nhazi nke njikọ ionic n'etiti cations na anions na eriri, enwere ike ịkwado ya na eriri pulp, ebe otu amide na-ejikọta ya na ìgwè hydroxyl na eriri iji mepụta njikọ hydrogen, nke na-eme ka ọ dịkwuo mma. ike njikọ dị n'etiti eriri.Mee ka ike akwụkwọ dịkwuo elu. Usoro mgbakwunye nke APAM tinyere rosin na aluminom sulfate nwekwara ike nweta mmetụta nkwado dị mma mgbe ejiri ya na pulp, mana mmetụta nkwado nke APAM ga-ebelata site na mmụba nke ọdịnaya ihe.
