Composition of Spray Drying Mixtures of Nonvolatile Ratio Control Group
| Nonvolatile ratio control | Ethanol (%) | Water (%) | SiO2-treated silicone (%) | B-98 (%) | B-76 (%) |
|---|---|---|---|---|---|
| Nonvolatile 5.00% | 85.00 | 10.00 | 4.38 | 0.31 | 0.31 |
| Nonvolatile 12.50% | 77.50 | 10.00 | 10.50 | 1.00 | 1.00 |
| Nonvolatile 16.00% | 74.00 | 10.00 | 14.00 | 1.00 | 1.00 |
| Nonvolatile 20.00% | 70.00 | 10.00 | 17.50 | 1.25 | 1.25 |
The polymer coating ratio, the ratio of sum of B-98 and B-76 among solid contents, was fixed to 16% in this group. The nonvolatile ratio control group was used to identify the relationship between particle size and characteristic of printed parts (Figs. 8a, d and 9a, d).
