PROCESSO PARA ELEVAR A EFICIENCIA DE POLIMERO REDUTOR DE ARRASTO |
| 摘要 |
<p>High molecular weight viscoelastic polymers are dissolved by passing the polymer solution through a die which "beads" the polymer allowing the formation of very fine filaments which are drawn into the flow. The beading and flow rate are balanced to maintain constant fine filament formation.</p> |
