4. Test condition

Test condition A:

40 grams of powder mixed with 4 grams of wax heated at 110°C for 15 minutes to make the wax melt. Then make the mixed powder pass through a 40-mesh sifter. 18 grams of the - 40-mesh powder is compressed at a 1.6´104N/cm2pressure to get a green sample for magnetic properties measuring.

Test condition B:

Compounding Equipment: Two roll rubber mill.

The two rollmill is heated to 80 °C . 32 grams of binder is sheeted onto the mill and 460 grams of BMXF-2H powder is added and mixed with the binder. This mill sheet is calendered onto another which roll gap is adjusted to produce a 2.7mm sheet. A portion of this mill sheet is evaluated to determine magnetic properties.
