Agglomeration of amorphous boron powder

Posted by tracy ma on Wednesday, May 23, 2012, In : metal powder 

Due to the surface acidic impurities, amorphous boron powder has poor compatibility with hydroxyl-terminated polybutadiene. For increasing boron amount in propellant, boron powder need modification treatment. Boron powder’s particle size is also an important factor affecting the process performance of the fuel-rich propellant. Boron combustion is slow and the ramjet fills fuel efficiency and is low. To consider from the agglomerate of combustion process, diameter of the boron particles shou...

Metal powder rolling

Posted by tracy ma on Monday, April 16, 2012, In : metal powder 

Metal powder rolling refers to the powder forming method which makes the metal powder though two rotating roll and continuous rolling into the porous or dense strip. After the powder in contact with the roller surface, only when the roll rotation (from the centerline of two roll) come to an angle, the powder can be roll bite and go into the deformation zone. The roll center of metal powder and roller surface contact angle is known as the bite angle. Its size mainly depends on the state of pow...
