ادامه مطلبPlaster Powder VOHP (Version "Out of the bag" HydroPerm) by Laura West and Mark Ganter. As a result of the collaboration between artist (and a bit engineer) Laura West and engineer (and more than part – artist) Mark Ganter, we are making great strides in the Fresno City College Sculpture Lab and the UW Solheim RP Lab for the past few weeks.
ادامه مطلبCeramic powders: There are very few types of ceramic powders that can be printed at the moment, therefore, limiting the use of binder jetting technology in other fields. Ceramic milling technology has some disadvantages as well. A more advanced milling process to produce ceramic powders having excellent overall performance is urgently needed.
ادامه مطلبCeramic powder processing consists of powder production by milling/grinding, followed by fabrication of green product, which is then consolidated to obtain the final product. A powder is a collection of fine particles. Synthesis of powder involves getting it ready for shaping by crushing, grinding, separating impurities, blending different powders, drying to form soft agglomerates.
ادامه مطلبCeramic Powders. Boron nitride is a man-made ceramic material prized for its excellent thermal and chemical stability and lubricating properties. Kennametal boron nitride powder is non-toxic and exhibits high electrical resistivity and temperature stability. It is oxidation resistant under inert atmospheres of temperatures up to 2200 degrees ...
ادامه مطلبDry roller granulation refers to the dry extrusion process in which the water content less than 10% Si3N4 ceramic powder is compressed into a sheet, and then the block-shaped material is transformed into a granular material in line with the requirements of use through the process of …

ادامه مطلبMichael Pfeifer, in Materials Enabled Designs, 2009. Ceramic Powder. Ceramic powder consists of ceramic particles and additives that improve a powder's ease of use during component fabrication. Additives include a binding agent to hold the powder together after compaction and a release agent to enable a compacted component to be easily removed from the compaction die.
