Sodium polyacrylate CAS 9003-04-7

Sodium polyacrylate waa budo cad. Aan ur lahayn oo aan dhadhamin. Aad u hygroscopic. Iskudhis polymer ah oo leh kooxo hydrophilic iyo hydrophobic. Si tartiib ah u milmay biyaha si ay u sameeyaan dareere hufan oo aad u muuqda, viscosity of 0.5% xalku wuxuu ku saabsan yahay Pa• s, viscous iyo sababtoo ah bararka nuugista biyaha (sida CMC, sodium alginate) oo la soo saaro, laakiin sababtoo ah ifafaale ionic kooxo badan oo anionic ah oo ku dhex jira molecule si loo kordhiyo silsiladaha molecular, waxqabadka viscous wuxuu kordhiyaa qaabka . Viscositykeedu waa qiyaastii 15-20 jeer ka CMC iyo sodium alginate. Daaweynta kuleylinta, cusbada dhexdhexaadka ah iyo asiidhyada organic waxay saameyn yar ku leeyihiin viscosity-keeda, halka viscosity alkaline uu kordho. Aan ku milmin dareerayaasha organic sida ethanol. Kuleylka xooggan ilaa 300 darajo ma burburo. Viscosity-ga waara wuu is beddelaa wax yar, ma fududa in la musuqmaasuqo. Sababtoo ah electrolyte-ka, waxay u nugul tahay aashitada iyo ion birta, iyo viscosity waa la dhimay.
