Closing digital-copyright.ca

The digital-copyright.ca domain was set up for a specific campaign that started in the summer of 2001 as the Canada DMCA Opponents forum.

The last post was in 2015 when that election was called, and all the electoral district boundaries would be changing.

While I won't be publishing the archive any more, all the pages are on Archive.org's WayBack Machine.

Notes on Mica Grinding

Mica is a hard-to-grind mineral (Bond work index 148). It remains platy particles even after grinding to an ultra-fine powder. Its flat size is always many times larger than its thickness. The thinner the thickness, the higher the strength and the higher the value.That is to say, the higher the aspect ratio, the higher the value of mica powder.

When designing the wet grinding process and selecting mica wet grinders, attention should be paid to the problem of scratches on the mica surface. The poor luster of mica powder will reduce its competitiveness.

Different uses of mica powder lead to different processes and different equipment. For those who want to engage in mica grinding, knowing the basic knowledge of mica grinding can avoid potential risks.
