Dispersant, flocculant
Iyo polyacrylamide dispersant muindasitiri yemapepa inonyanya kunzi cationic polyacrylamide ine huremu hwakaderera.Nekuti cheni yayo yemamorekuru ine mapoka e-carboxyl, ine mhedzisiro yekuparadzira pamafibhi akashata, inogona kuwedzera viscosity yepulp, inobatsira kune fiber kumiswa, uye inogona zvinobudirira Inogona kuvandudza kufanana kwepepa, uye inoshanda zvakanyanya. dispersant for long fibers.Amphoteric polyacrylamide inoshandiswa se flocculant yekurapa mvura muindasitiri yemapepa.Boka rayo reamide rinogona kuumba hydrogen zvisungo nezvinhu zvakawanda mumvura yetsvina, saka rinogona kushambadza zvimedu zvakaparadzirwa mumvura pamwe chete nekuzvibatanidza.Inobatsira kugadzirisa uye kusefa kwezvikamu.Kana ichienzaniswa nemamwe inorganic flocculants, amphoteric polyacrylamide ine zvakanakira yemhando dzakakwana, kushoma kudyiwa mukugadzirwa, kukurumidza kugadzirisa kukurumidza, kushoma kwekugadzira sludge, uye nyore mushure mekurapa, nezvimwewo, izvo zvinogona kusangana nezvinodiwa zvakasiyana-siyana marara emvura.
Kupfupisa, polyacrylamide inoita basa rakakosha muindasitiri yemapepa.Inogona kushandiswa seajenti yekuenzanisa mapepa, inosimbisa agent, dispersant, filter aid, etc. Chinangwa chayo ndechekuvandudza kufanana kwepepa, kunyatsovandudza kunaka uye kusimba kwepepa, uye zvakare kunatsiridza chiyero chekuchengetedza mafiritsi uye fibre dzakanaka, kuderedza Kuderedza kurasikirwa kwezvinhu, kunatsiridza kusefa kudzoreredza kunyatsoshanda uye kuderedza kusvibiswa kwezvakatipoteredza.
CPAM inoshandiswa sechinhu chinosimbisa, kuburikidza nekugadzirwa kweionic zvisungo pakati pe cations uye anions pafibers, inogona kuvharidzirwa pamapulp fibers, nepo mapoka emamide achibatana nemapoka ehydroxyl pamafibers kuti agadzire hydrogen bond, iyo inosimudzira. simba rinosunga pakati pemafibhi.Wedzera simba remapepa.Kuwedzera kutevedzana kweAPAM pamwe nerosin uye aluminium sulfate inogonawo kuwana zvirinani kusimbisa kana yakashandiswa mu pulp, asi iyo yekusimbisa mhedzisiro ye APAM inoderera nekuwedzera kweiyo filler content.
