【摘要】：在自主研發(fā)設(shè)計(jì)的非標(biāo)離心機(jī)上,利用離心分離生物液體的原理對超細(xì)粉體進(jìn)行離心壓縮,獲取最終產(chǎn)品;對粉體離心壓縮動力學(xué)行為進(jìn)行理論分析,探討粉體在沖擊壓縮條件下的壓縮規(guī)律,研究壓縮過程中壓力與粉體孔隙率的非線性關(guān)系;通過對白炭黑和硅鎂粉超細(xì)粉體壓縮實(shí)驗(yàn)研究,獲取基于離心壓縮方式下的壓力與粉體體積減小率的動力學(xué)方程。結(jié)果表明:在離心壓強(qiáng)為0~0.3 MPa時(shí),白炭黑和硅鎂粉的表觀密度與壓強(qiáng)的關(guān)系可通過Heckel方程坐標(biāo)表征,曲線特征符合二次函數(shù)規(guī)律。
[Abstract]:On the non-standard centrifuge designed by ourselves, the ultrafine powder was compressed by centrifugation and the final product was obtained by centrifugal separation of biological liquid, and the kinetic behavior of centrifugal compression of powder was analyzed theoretically.This paper discusses the compression law of powder under impact compression, studies the nonlinear relationship between pressure and porosity of powder during compression, and studies the compression experiments of silica and magnesia powder ultrafine powder.The kinetic equations of pressure and powder volume reduction under centrifugal compression were obtained.The results show that when the centrifugal pressure is 0. 3 MPa, the relationship between the apparent density and pressure of silica and magnesium silicate powder can be characterized by the coordinate of Heckel equation, and the characteristic of the curve accords with the law of quadratic function.
