20 terms for abrasives

1. Abrasive: Material that plays a cutting role in grinding, polishing, and polishing of objects

2. Abrasive: A granular material made by manual methods to a specific particle size, used to manufacture grinding, polishing, and grinding tools for cutting off excess material

3. Particle size: measurement of abrasive particle size and diameter

4. Micro powder: ordinary abrasive particles not coarser than 240 grit, abrasive particles or superhard abrasive particles finer than 36/54 μ m

5. Coarse abrasive particles: The diameter of abrasive particles with particle sizes ranging from 4 to 220. Abrasives of size 12 and above need to be processed using special techniques and customized in advance

6. Particle size number: a grading mark made according to the execution standard for the size and diameter of abrasive particles

7. Single crystal: The arrangement of crystal atoms is very regular, with a regular shape and anisotropy

8. Polycrystalline: a crystal shape composed of many small grains with different orientations

9. Magnetic material: a general term for the amount of magnetism of magnetic substances in abrasive grains

10. Resting angle: The angle between the conical surface and the bottom surface of the cone formed by the abrasive sample falling from a certain height through a funnel onto a horizontal metal plate. The angle of repose is generally calculated from the diameter and height of a cone

11. Bulk density: The mass of abrasive particles per unit volume of air in natural accumulation, measured in g/cm3

12. Natural abrasives: abrasives made directly from natural mineral rocks after sorting, crushing, grading, or other processing treatments

13. Capillary phenomenon: Grinding particles are placed in a glass test tube with a certain diameter, and the lower end is immersed in water. Within a given time, the height of water rise (mm)

14. Artificial abrasives: abrasives refined or synthesized by artificial methods. The abrasives of Abrasive Industry Co., Ltd. are artificial abrasives

15. Specific surface area: The total surface area per unit mass of abrasive, measured in m2/g

16. Impact toughness: the impact resistance and crushing performance of abrasives

17. Compressive strength: The load value and unit N of a single abrasive particle during crushing under static pressure

18. Free abrasives: abrasives that are directly ground or polished in a free state

19. Particle size composition: a combination of grading marks made by a nominal particle size number and abrasive particle size

20. Mixed particle size: The abrasive particle size composed of two or more particle sizes mixed in a set ratio
