2. Procedure Summaries

  1. Before production,the powders should avoid being humidified,and avoid being mixed with other material and impurity.
  2. The mixture retio of binders and plasticizers should be defined according to the grade of the powder.The powder and binders and plasticizers should be mixed uniformly.
  3. The working temperature of extruding should be controlled between 50OC to 90OC.(calendaring plate is usually between 80OC to 120OC)
  4. Please adjust the extruding speed,calendaring speed and times,according to the property required.
