Important Standards of High-grade Silicon Carbide Abrasive Grains

Today, we will discuss the important standards of high-grade silicon carbide abrasive grains in the following four aspects:

A, Cleanliness:

If you put some abrasive grains in the water glass for stirring, please observe whether the water is clear or cloudy or there are some suspended solids. If the cleanliness of abrasive surface is poor, even great adhesives are also in vain.

B, The chemical content of abrasive grains:

Chemical content = abrasive purity

The content of silicon carbide (p12-220) > 99.50%

The content of silicon carbide (p240-400) > 99%

The content of silicon carbide (p500-1200) >98.50%

The content of silicon carbide (1500-3000) > 98.00%

Ferric oxide < 0.15%

Free carbon < 0.15%

Magnetic materials < 0.005

C, The shape of abrasive particles

The grinding efficiency is more important than the degree of finish. The more needle or slice shape the better.

Grinding efficiency and degree of finish are both important, and the shape of abrasives is in polygon or equivalent solid.

D, There is only one that does not comply with the above standards, and they are low-grade abrasives.

Other indicators (such as particle size, etc.) can be finished according to customer's requirements.
