Compacting pressure and relative density compacts the first three weeks the book to help other: YF06 carbide nano powder compression properties of more teaching Yong 0.16810l11J1 () 182 () compacting pressure,Moncler online, kN / clit: ~ Figure 5, two powder compacting pressure and the elastic aftereffect coefficient in the YF06 powder compacting pressure and the relationship between the relative density of compacts was: Y = 6.930 +0.822 xX (4) where, Y a pressing pressure in kN / cm; X an Compacts elastic aftereffect coefficient (%). From (3) and (4) can also be seen powder compacts of nano YF06 aftereffect coefficient of elasticity increases with the compaction pressure increased dramatically,stivali ugg, more (3) and (4) the slope can be seen, YF06 powder YT5 than normal carbide powder compacts elastic aftereffect much larger. (1) and (2) in the suppression of pressure (2 ~ 15) kN / cm to fit inside the range. Figure 6 Two powder compacts with green density elastic aftereffect increases rapidly,, YF06 density of powder compacts reached 50% after the green density is difficult to increase the pressure in the large suppression be a huge elastic aftereffect. 4 Conclusion l,ugg boots günstig, YF06 PEG nano-cemented carbide powder is spray granulation and bulk density increase liquidity and improve the performance of its suppression; can get 50% of the relative density of compacts. Water 2 () J5 cut 10 songs i30 ~ t0506070 compacts relative density,% Figure 6, the relative density of compacts and compacts between elastic aftereffect coefficient of 2, YF06 carbide nano powder compaction pressure than normal carbide powder Multi-suppression pressure; and with the increase of green density increases rapidly; the relative density of compacts 54% 1t. 1 -, compacting pressure is normal pressure on the suppression of carbide powder 9 times. 3,air jordans, YF06 elastic aftereffect of nano cemented carbide powder carbide powder than normal elastic aftereffect is also large; when the green density more than 50%, the increase in green density is difficult to suppress the increase of pressure can only increase elastic aftereffect.
