Alumina's International Standards and National Standards

The national standards generally adopt traditional chemical analysis methods to analyze the composition grade of alumina, and the method is cumbersome. According to the analysis cycle, it strictly follows the requirements of GB/T 15000.1-15000.5-1994 and YS/T409-1998 standards, after sample pre

What benefits can OMV bring to users? First of all, through the above two states of using OMV or not using OMV, we can see that the biggest bright spot is to improve the productivity and efficiency of the process. Imagine that it is no longer necessary to manually measure and change to CNC

Floating nut design and application (Figure)

In mechanical motion, the most common transmission for linear motion is the screw drive. The linear motion of the nut is driven by the rotary motion of the screw, which is the most frequently used in our design. This paper discusses the structural design of the sliding helix.
