Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mica plate production, and particularly relates to a mica plate production device. BACKGROUND

[0002] Mica plate is a kind of plate material made of multiple layers of mica paper bonded by silicone resin, which is widely used in the field of electrical insulation. In order to ensure that the mica plate has sufficient bonding strength and avoid delamination, the silicone resin usually needs to be cured under high temperature and high pressure conditions.
