Retention rate and expansion rate and viscosity of IDF (70%) were increased to 18%, 54% and 116% respectively after soaked in water, and expansion rate and viscosity of IDF (90%) were increased to 94%, 41%, but retention rate of it was decreased to 16%.

• 在所试验的条件中,低温浸泡后超微粉碎可使IDF(70%25)的持水率、膨胀率和黏度上升18%25、54%25和116%25; 可使IDF(90%25)的膨胀率和黏度上升94%25和41%25,但持水率下降16%25。
