CELLULOSE-BASED MAGNETIC ION EXCHANGE RESIN Ⅰ. PARTICLE SIZE AND DISTRIBUTION OF THE RESINS |
| |
| Abstract: | The viscose (sodium cellulose xanthate) containing fine γ-Fe_2O_3 or Fe_3O_4 was suspended in oil with stirring at high speed, in which it Was dehydrated and granulated at 80-100℃. to give the magnetic resin with particle size smaller than 150μm. The effect of the controlling factors such as magnetic powder, oils, surfactants and the speed of stirring on the particle size and distribution of the resin was investigated and discussed. |
