7.1 绪言 离心沉淀是建立在固相和液相或两种都是液相两个相位之间密度差的基础上的,颗粒在离心力的作用下,通过液体向外或向内(视颗粒的密度比液相高或低而定)作径向运动。于是,离心分离可以看作是重力沉淀分离细颗粒的一种延伸,它也可以分离通常在重力场内无法分离的乳化液。 沉淀离心机由一个无孔转筒构成,进入离心机的悬浮液以很高的速度转动。液体通过撇
7.1 INTRODUCTION Centrifugal precipitation is based on the difference in density between the solid phase and the liquid phase or both phases of a liquid phase. Particles move outwardly or inwardly (depending on the density of the particles Higher or lower than the liquid phase) for radial movement. As a result, centrifugation can be viewed as an extension of the separation of the fine particles by gravity precipitation, and it also separates emulsions that are normally not separable in the gravitational field. The sedimentation centrifuge consists of a non-perforated drum and the suspension into the centrifuge rotates at a high speed. Liquid passes through the skimmer
