本机型还可以实现粉体电阻、电阻率、电导率的测量（导体粉末），可通过粉体压缩与阻抗的变化关系或者粉末体压缩过程中的静电测量（绝缘粉体颗粒）.通过电性能的变化来判断粉体压缩特性. During compression , particle need undergo preliminary compression, particle rearrangement, the initial structure formation, elastic deformation, plastic deformation and grain crushing, combined with the key form, further compaction and of elasticity after removal the stress /span> series of change, such as granular structure destruction and restructuring to form a new bonding and compressed; By applying the principal stress to the deformation of the powder to yze The volume change of the powder body and the pressure relation,(namely The relationship between primary stress and powder density), the relation between time and yield strength, yield strength and compression height change relations, using the empirical equation method: Heckel, Kawakita, Adams equations /span>the compression theory of Kawakita’s Equation of linear regression equation to yze the new powder particles, research and development of solid products such as predictive ysis tools in drug prescription and process selection and Compaction density is required for pressure etc.
This model can realize measurement of powder resistance, resistivity, conductivity( conductor powder),Judging powder’s compression feature through the change of relationship between compression and impedance or powder body ‘s electrostatic measurement In the process of powder compression. (insulation powder particles).
二、目前的压缩成形机理At present, recognized mechanism of compression forming is：
