How to Understand the Specification of Flake Graphite?

Release time: 2019-11-11

We always meet flake graphite with a non-integer specification, for example, 195Mesh. What does it mean when the Mesh is an integer? Does 195Mesh mean 195 holes per inch of screen mesh? It's obviously not. In the following, we will take flake graphite of 195Mesh as an example to help you understand our common specifications of flake graphite.

 

1.The meaning of "±"

 

The specification of flake graphite is determined by screen mesh. In general, as the particle size is difficult to be accurately expressed by size, the size of the screen mesh is represented by Mesh. For convenience of measurement, Mesh is mostly expressed by a multiple of 10. When the flake graphite is too large to pass through the screen mesh and can not meet the requirements of larger particle size, we use the signal of “±” to make it easy to distinguish.

 

The "+" before the flake graphite specification means that the particle size of the flake graphite is larger than the size of screen mesh hole, and the "-" means that the particle size of the flake graphite is smaller than the size of screen mesh hole. "+195Mesh" flake graphite refers to the flake graphite that can not pass through the 100Mesh screen mesh, and the "-195Mesh" flake graphite refers to the flake graphite that can pass through the 100Mesh screen mesh.

 

2.The meaning of numbers

 

The common specification of flake graphite is three-digit number, but the number is not an integer multiple of 10. The first digit is the Mesh of screen mesh we are talking about, and the last two digits are the carbon content of flake graphite. While purchasing the flake graphite, a standard for differentiating the flake graphite specifications is generally indicated by the combination of the percentage of carbon content and the Mesh. 195Mesh flake graphite refers to high carbon flake graphite with particle size of 100Mesh and carbon content of 95%.

 

In general, ±195Mesh flake graphite is 100Mesh flake graphite with 95% carbon content. Other specifications can be understood in the same way.
