Polyacrylamide waa polymer toosan, badeecada waxaa inta badan loo qaybiyaa budo qalalan iyo kolloidal laba nooc. Marka loo eego celceliska miisaanka unugyada, waxaa loo qaybin karaa miisaan yar oo kelli ah (<1 milyan), miisaanka molecular dhexdhexaad ah (2 ~ 4 milyan) iyo miisaanka molecular sare (> .7 million) . Sida ku cad qaab-dhismeedkeeda waxaa loo qaybin karaa mid aan ahayn - ionic, anion iyo cationic. Kala-baxa biyaha (HPAM) ee nooca anion. Silsiladda ugu weyn ee polyacrylamide waxay ka kooban tahay tiro badan oo ah kooxaha amide, oo leh dhaqdhaqaaq kiimiko oo sarreeya, waana la bedeli karaa si loo soo saaro waxyaabo badan oo ka mid ah polyacrylamide. Alaabooyinka ayaa si weyn loogu isticmaalay waraaqaha samaynta, farsamaynta macdanta, soo saarista saliidda, biraha, qalabka dhismaha, daaweynta wasakhda iyo warshadaha kale. Sida saliidaha, wakiilka ganaaxa, xasiliyaha dhoobada, wakiilka barakaca saliida, wakiilka yaraynta khasaaraha biyaha iyo wakiilka dhumucdiisuna, polyacrylamide ayaa si weyn loogu isticmaalay qodista, aashitada, jabinta, xidhidhiyaha biyaha, sibidhka, soo kabashada saliidda sare iyo soo kabashada saliidda sare.

Codsiga

1.daabacaadda iyo midabaynta daaweynta biyaha wasakhda ah

Daabacaadda iyo midabaynta daaweynta biyaha wasakhda ah, halkii laga isticmaali lahaa xinjirowga molecule hooseeya ee dhaqameed, marka loo eego qiyaasta dhaqameed ee weyn ee xinjirowga, waxtarka xinjirowga ayaa sarreeya, xaaladaha ph ugu fiican sida soo socota: 8.0.

2.Waraaqo samaynta biyaha wasakhda ah

Daawaynta biyaha wasakhda ah ee waraaqaha loo isticmaalo sidii xinjirowga lidka ku ah polyaluminum chloride, aluminium sulfate, iwm, ayaa sidoo kale loo isticmaali karaa nadiifinta dhoobada warqad-samaynta.
