Binciken fasahar samar da polyacrylamide

Tsarin samar da polyacrylamideya haɗa da batching, polymerization, granulation, bushewa, sanyaya, murƙushewa da marufi. A albarkatun kasa shiga cikin dosing kettle ta cikin bututun, ƙara da daidai Additives zuwa gauraye ko'ina, sanyaya zuwa 0-5 ℃, da albarkatun kasa da aka aika zuwa polymerization tukunyar jirgi ta nitrogen deoxygenation, oxygen abun ciki an rage zuwa game da 1%, ƙara da initiator ga polymerization, bayan polymerization, da roba block ne yankakken, aika zuwa ga pellet granulated pellet granulated bushe pellet. Ana aika kayan busassun zuwa tsarin murkushewa da nunawa don murkushewa. Bayan murkushewa, kayan yana shiga cikin tsarin marufi don shiryawa kuma ya samar da samfurin da aka gama.

Dabarar samar da monomer

Samar da acrylamide monomer yana dogara ne akan acrylonitrile azaman albarkatun ƙasa, a ƙarƙashin aikin mai haɓaka hydration don samar da ɗanyen samfurin acrylamide monomer, bayan walƙiya mai walƙiya, mai ladabi acrylamide monomer, wannan monomer shine albarkatun ƙasa don samar da poly444 acrylamide.

Acrylonitrile + (ruwa mai kara kuzari/ruwa) → hade → danyen acrylamide → filashi → mai ladabi → mai ladabi acrylamide.
