The grinding and polishing performance of the belt is mainly based on abrasives. The substrate is a carrier.
Important standards for high-grade silicon carbide abrasives:
The abrasive is placed in a glass water bottle for agitation, clear or turbid, with or without suspended solids. Abrasive surfaces are poorly cleaned, and even better binders are in vain.
2: Chemical content of abrasive:
Chemical content = abrasive purity
Silicon carbide content (p12--220)>99.50%
Silicon carbide content (p240---400>99%
Silicon carbide content (p500---1200)>98.50%
Silicon carbide content (1500--3000)>98.00%
Ferric oxide <0.15%
Free carbon <0.15%
Magnetic material <0.005
3: Abrasive grain shape
Only grinding efficiency is required, no finish is required, and the more needle-like pieces, the better.
Both grinding efficiency and smoothness are required, and the shape of the abrasive should be multi-prism and equal.
4: One item (including small items) does not meet the above criteria and is low grade abrasive.
Other indicators (such as: particle size composition, etc.) are normally done according to customer requirements.
