MECHANISM ABOUT RESTRAIN AND RETENTIONS ON SILICA IN WHEAT STRAW PULP WITH OXIDES ADDITION
The mechanism of silicon retention oxides was studied using modern surface analysis techniques. The cooking conditions with oxide addition were optimized by means of uniform design, and different micro-morphology of fiber surface, the cell wall and different valence state were analyzed using multi-media microscope, Environmental Scanning Electron Microscopy and X-ray photoelectron spectroscopy. The results showed that more precipitation of the silica onto the pulp occurred under the optimum conditions compared to the Soda-AQ pulp. The mechanism of silicon retention by oxide was that silica compound reacted with silica dioxide and then was covered onto the epidermal cell groups as a layer of insoluble material.
