Mica board production process

The manufacturing process of mica boards generally includes several stages such as production preparation (controlling the solid content of the adhesive), film application, restriction, maintenance, inspection, and packaging.

Soft mica sheets require strict control of baking temperature and flexibility.

Various soft mica sheets cannot be piled up thickly, so they must be stored in a dry and ventilated place. Mica board production modeling The drying time of mica should not be too long. In order to ensure plasticity, hot pressing is generally used.

The key to the commutator mica sheet manufacturing process is the limitation. In order to improve the tightness and integrity of the mica flakes and avoid adhesion and slippage, the switchboard mica requirements are divided into secondary restrictions.

The mica flakes that have passed the first restriction must go through the second restriction after processing. The production process of liner mica is basically the same as that of exchanger mica, but it is generally of thick specification, so it requires long confinement time and high preheating and hot pressing temperatures.
