1.Bulk density

Principle: Archimedean principle and buoyancy method. The equation is formed by the derivation and transformation of the buoyancy and density calculation formula. First, a high-precision solid analytical balance is used to calculate the weight of the sample in the air (W1) and the weight in the water (W2), and the W1-W2 value is calculated. The density of water is ρ=1 by default. By establishing the equation Vsample=Vdrainage, the density of the sample can be calculated: ρ=W1/(W1-W2)xρwater.


2.Loss bulk

Principle: Through the sandblasting device, alumina ceramic sheets of specific specifications are sprayed and worn under specified conditions to cause wear on the surface of the sample. The mass loss of the sample is measured by weighing method, and the wear volume of the sample is calculated based on the mass loss of the sample divided by the volume density.


3.Rockwell hardness

Principle: A test force of a specific size, shape and material is divided into two levels according to the regulations and pressed into the surface of the specimen. After the initial test force is applied, the initial indentation depth is tested. Then the main test force is applied, and the final indentation depth is measured while the initial test force is maintained after the main test force is unloaded. The Rockwell hardness is calculated based on the difference h between the final indentation depth and the initial indentation depth and the constants N and S through the formula Rockwell hardness = N-h/S.
