【摘要】 为了改善小颗粒陶瓷核燃料微球的尺寸分布,并控制其直径,用振动控制溶胶喷射流分散过程,制得了相应的均一溶胶滴。溶胶喷射流速度及相应振动频率高时用载带流保护溶胶滴,而低时不用,制得了不同直径的小颗粒均一湿凝胶微球。通过微球的直径测量,验证了液体喷射流振动分散的原理。更多还原

【Abstract】 In order to improve the size distribution and to control the diameter of fine ceramic nuclear fuel microspheres, the dispersion process of Sol jet is controlled by vibration; and the corresponding uniform Sol drops have been prepared. The uniform fine Gel microspheres with different diameters have been fabricated by using carrying-fluid to protect the formed Sol drops when the velocity of Sol jet and the corresponding vibration frequency are high; the carrying-fluid is not necessary when those are not high. The principle of vibration dispersion of liquid jet has been tested and verified by the diameter measurements of the Gel microspheres.更多还原
