Polyacrylamide(PAM) Codsiga
Daaweynta biyaha:
Codsiga PAM ee warshadaha sifaynta biyaha inta badan waxaa ku jira saddex waji: daaweynta biyaha ceeriin, daaweynta wasakhda iyo daaweynta biyaha warshadaha.
Daawaynta biyaha ceyriinka ah, PAM waxaa lala isticmaali karaa kaarboon firfircoon si ay isugu ururiso oo ay u caddeyso walxaha la hakiyey ee biyaha nool.
Soosaarka saliidda:
Ka faa'iidaysiga saliidda, PAM waxaa inta badan loo isticmaalaa qodista alaabta dhoobada iyo hagaajinta heerka wax soo saarka saliidda waxaana si weyn loogu isticmaalaa qodista, dhamaystirka ceelasha, sibidhka, jabinta, iyo kor u qaadida wax soo saarka saliidda.Waxay leedahay hawlaha kordhinta viscosity, hoos u dhigista luminta sifaynta, habaynta rheological, sibidhka, kala-duwanaanta, iyo hagaajinta astaanta.
Waqtigan xaadirka ah, wax soo saarka saliidda ee Shiinaha ayaa galay marxaladda dhexe iyo dambe, si loo hagaajiyo heerka soo kabashada saliidda, hagaajinta saamiga socodka saliidda-biyaha, si loo kordhiyo saliidda cayriin ee alaabta la soo saaray.
Warqad-sameynta:
PAM waxa si weyn loogu isticmaalaa sida wakiilka degane, shaandhada shaandhaynta iyo homogenizer samaynta waraaqaha.
Polyacrylamide waxaa inta badan loo isticmaalaa warshadaha waraaqaha laba dhinac: mid waa in la hagaajiyo heerka haynta ee buuxinayaasha, pigments, iwm, si loo yareeyo khasaaraha alaabta ceeriin iyo wasakhowga deegaanka;
Dharka, daabacaadda iyo midabaynta:
Warshadaha dharka, PAM waxaa loo isticmaali karaa sida wakiilka cabbirka iyo wakiilka dhamaystirka ee daaweynta ka dib ee dharka si loo soo saaro lakabka ilaalinta jilicsan, ka-hortagga laalaabka iyo ka-hortagga caaryada.
Iyada oo ay leedahay hygroscopicity xooggan, heerka jebinta wareegga waa la yarayn karaa.
PAM oo ah wakiilka daawaynta ka dib waxay ka hortagi kartaa korontada taagan iyo dabciga marada.
