Simply put, modification is the process of intentionally altering the surface or bulk properties of a material through physical, chemical, or mechanical methods to give it functions it did not originally possess or to improve its performance, thereby meeting specific application needs.

Oil absorption value refers to the volume (in milliliters) of a specific liquid (commonly linseed oil or castor oil) absorbed by 100 grams of powder material when it reaches a specific viscous state (such as forming uniform clumps). The unit is usually mL/100g.

In industrial production and materials science, moisture generally refers to the total amount of water contained in a substance. However, based on the form and state of water's existence, it can be subdivided into several levels:

LOI, often abbreviated as LOI, refers to the percentage of mass lost by a material after it has been burned for a sufficient period of time at a specific high temperature, relative to the original sample mass.

Particle size, as the name suggests, refers to the size of a single powder particle. However, since powder is an aggregate of countless particles, these particles are usually not all the same size. Therefore, in practical industry and scientific research, the concept of "particle size" typically encompasses three aspects:
