| MATERIAL: |
Polyurethane flakes. 1/4" x 1/16" x 1/16". Estane in Cyclo Hexanone or Tetra Hydro Furan or Methyl Ethyl Ketone. |
|
PROBLEM: |
Dissolve flakes in solvent to make clear liquid resin for magnetic coating. Obtain correct viscosity and molecular weight. |
|
RESULTS: |
Flakes easily ground in first pass. Recirculated slurry at 15-20 gpm. Dissolved rapidly. |
|
AB MIXER: |
Model 3 x 1.5 toothed impeller/liner, 5 HP, 3600 RPM, 1/4" grid. Mounted vertically below tank. |
| BENEFITS |
Estane chips rapidly dissolved without reducing molecular weight or lowering viscosity. Finished liquid resin is clear. No "fish-eyes" or specks. |
