Technology: Introduction to the analysis of the working principle of ultracentrifuge

When the suspension containing fine particles is standing still, the suspended particles gradually sink due to the action of the gravity field. The heavier the particles, the faster they sink, otherwise the particles with a lower density than the liquid will float up. The speed of particles moving under the gravity field is related to the size, shape and density of the particles, and is related to the strength of the gravity field and the viscosity of the liquid. Like red blood cell-sized particles with a diameter of a few microns, their sedimentation process can be observed under normal gravity.

In addition, when the substance settles in the medium, it is accompanied by a diffusion phenomenon. Diffusion is absolute and unconditional. Diffusion is inversely proportional to the mass of the substance, the smaller the particle, the more serious the diffusion. The settlement is relative, conditional, and can only be exercised by external forces. The sedimentation is proportional to the weight of the object, the larger the particles, the faster the sedimentation. For particles smaller than a few microns, such as viruses or proteins, which are in a colloidal or semi-colloidal state in solution, it is impossible to observe the sedimentation process using gravity alone. Because the smaller the particles, the slower the settling, and the more serious the diffusion phenomenon. Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force in order to force these particles to overcome the diffusion and generate a settling motion.

Vacuum forming is a manufacturing process by which a sheet of plastic is heated and pressed over a form to create a part. This process is used to create many of the products in your home such as plastic containers, tubs, sink units, and electrical enclosures.



Thick Sheet Vacuum Forming Machine is main for 2-10mm of material


if less 5mm ,then could with single heating to do.


More than 5mm ,by two later heating system to heating ,then increase blow function ,products will be more better
