How many types of mica boards are there?

Phlogopite fiberglass fire-resistant mica boards are widely used in high-rise buildings, underground railways, large power stations and important industrial and mining enterprises and other places related to fire safety and fire protection, such as power supply lines and control of emergency facilities such as fire fighting equipment and emergency guide lights. line. Because of its low price, it is the best material for fire-resistant cables.

A. Double-sided mica tape: Take mica board as the base material, and use glass fiber cloth as double-sided reinforcing material, which is mainly used as a fire-resistant insulating layer between the core wire and the outer skin of fire-resistant cables. It has better fire resistance and is recommended for general engineering use.

B. Single-sided mica tape: The phlogopite paper is used as the base material, and glass fiber cloth is used as a single-sided reinforcing material. It is mainly used as a fire-resistant insulation layer for fire-resistant cables. It has better fire resistance and is recommended for general engineering use.

C. Three-in-one mica tape: using phlogopite board as the base material, using glass fiber cloth and carbon-free film as single-sided reinforcing material, mainly used for fire-resistant cables as fire-resistant insulation. It has better fire resistance and is recommended for general engineering use.

D. Double film tape: use phlogopite board as the base material, and use plastic film for double-sided reinforcement, mainly used for motor insulation. The fire-resistant performance is poor, and the use of fire-resistant cables is strictly prohibited.

E. Single film tape: use phlogopite paper as the base material, and use plastic film for single-sided reinforcement, mainly used for motor insulation. The fire-resistant performance is poor, and the use of fire-resistant cables is strictly prohibited.
