Polyacrylamide (PAM) yog cov dej-soluble polymer ua los ntawm acrylamide subunits. Nws muaj cov nyhuv tshwj xeeb los ua kom cov viscosity ntawm dej los yog txhawb cov flocculation ntawm cov khoom tam sim no hauv dej, nws tuaj yeem txo cov kev sib txhuam ntawm cov kua. Muaj 3 yam sib txawv ntawm polyacrylamide, raws li lawv cov yam ntxwv ion, uas yog: non-ionic, cationic thiab anionic polyacrylamides. Non-ionic polyacrylamide yog tsim rau kev sib cais cov organic thiab inorganic ncua kev kawm ntawv, qhov twg cov tshuaj yog nruab nrab los yog acidic. Cationic polyacrylamide yog tsim rau kev tshem tawm cov kev daws teeb meem uas muaj cov khoom siv organic thiab muaj cov nqi tsis zoo. Anionic Polyacrylamide yog qhov tsim nyog ntom ntom, Inorganic Kev Ncua Sijhawm thiab yog nruab nrab lossis yooj yim, nrog cov tuab tuab ntawm 1, {hli.
Cov khoom siv Polyacrylamide yuav tsum tau muab khaws cia rau hauv qhov chaw cua, qhuav thiab kub-resistant, thiab thauj cov dej tsis zoo thiab tsis muaj dej pov thawj. Thaum lub sijhawm thauj mus los, ua tib zoo saib xyuas kom tsis txhob muaj cua sov thiab noo noo thiab tsis txhob cuam tshuam pob. Rau cov khoom Polyacrylamide tom qab unpacking, ua tib zoo kaw lub hnab ntim khoom ua ntej siv, npliag cov pa hauv lub hnab thiab zam atomization thiab hardening ntawm Polyacrylamide.
