Today, I will learn the basic knowledge of mica tape with you!
Fire-resistant mica tape, referred to as mica tape, is a fire-resistant insulating material,
It can be divided into fire resistant mica tape for motor and fire resistant mica tape for fire resistant cable.
According to the structure, it can be divided into: double-sided belt, single-sided belt, three-in-one belt, double-film belt, single-film belt, etc.
According to mica, it can be divided into synthetic mica belt, phlogopite belt and muscovite belt.
Normal temperature performance: synthetic mica belt is the best, followed by mica belt, and phlogopite belt is the worst. High temperature insulation performance: synthetic mica belt is the best, followed by mica belt, and mica belt is the worst
High temperature resistance: synthetic mica tape fluorophlogopite tape, which does not contain crystal water, has a melting point of 1375 ℃, a large safety margin, and has the best high temperature resistance. Phogopite releases crystal water above 800 ℃, followed by high temperature resistance. Muscovite releases crystal water at 600 ℃, and has poor high temperature resistance. Fire-resistant mica tape for fire-resistant cable is a high-performance mica insulating product, It has excellent high-temperature resistance and combustion resistance. The mica tape has good flexibility under normal conditions, and is suitable for the main fire-resistant insulation layer of various fire-resistant cables. There is basically no volatilization of harmful smoke when burning with open fire, so this product is not only effective but also safe for cables.

1. Synthetic mica refractory mica tape
Synthetic mica is an artificial mica with large size and complete crystal form, which is synthesized by replacing hydroxyl with fluorine ion under normal pressure. Synthetic mica tape is made by taking mica paper made from synthetic mica as the main material, and then pasting glass cloth on one or both sides with adhesive. The glass cloth pasted on one side of mica paper is called "single-sided tape", and the one pasted on both sides is called "double-sided tape". In the manufacturing process, several structural layers are bonded together, then dried in the furnace, then rolled, and then cut into different specifications of tapes. In addition to the characteristics of natural mica tape, such as low expansion coefficient, high dielectric strength, high resistivity and uniform dielectric constant, the synthetic mica tape is mainly characterized by high heat resistance and can reach Class A fire resistance level (950-1000 ℃)
The temperature resistance of synthetic refractory mica tape is greater than 1000 ℃, the thickness range is 0.08~0.15mm, and the maximum supply width is 920mm.
A. Double-sided synthetic fire-resistant mica tape: synthetic mica paper is used as the base material, glass fiber cloth is used as the double-sided reinforcement material, and silicone adhesive is used for bonding. It is the most ideal preferred material for manufacturing fire-resistant wires and cables. It has the best fire resistance and is recommended for key projects.
B. Single-sided synthetic fire-resistant mica tape: synthetic mica paper is used as the base material, and glass fiber cloth is used as the single-sided reinforcement material. It is the most ideal preferred material for manufacturing fire-resistant wires and cables. Good fire resistance, recommended for key projects.

2. Phogopite fire-resistant mica tape
The phlogopite fire-resistant mica tape has good fire resistance, acid and alkali resistance, corona resistance and radiation resistance, as well as good flexibility and tensile strength, and is suitable for high-speed winding. The fire resistance test shows that the wires and cables wrapped with phlogopite tape can ensure no breakdown for 90 min under the condition of 840 ℃ and 1000V voltage.
The phlogopite glass fiber fire-resistant belt is 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 fighting and lifesaving, such as the power supply lines and control lines of emergency facilities such as fire fighting equipment and emergency guide lights. Because of its low price, it is the preferred material for fire-resistant cables.
A. Double-sided phlogopite fire-resistant mica tape: use phlogopite paper as the base material and glass fiber cloth as the double-sided reinforcement material, mainly used as the fire-resistant insulating layer between the core and the sheath of the fire-resistant cable. Good fire resistance, recommended for general engineering use.
B. Single-sided phlogopite fire-resistant mica tape: use phlogopite paper as the base material and glass fiber cloth as the single-sided reinforcement material, mainly used for fire-resistant cable as the fire-resistant insulation layer. Good fire resistance, recommended for general engineering use.
C. Three-in-one phlogopite fire-resistant mica tape: it uses phlogopite paper as the base material, glass fiber cloth and carbon-free film as single-sided reinforcement material, and is mainly used for fire-resistant cables as fire-resistant insulation layer. Good fire resistance, recommended for general engineering use.
D. Double-film phlogopite tape: use phlogopite paper as the base material and plastic film as double-sided reinforcement, mainly used for motor insulation layer. The fire resistance is poor, and the use of fire resistant cables is strictly prohibited. E. Single-film phlogopite tape: It uses phlogopite paper as the base material and plastic film as the single-sided reinforcement, mainly used for the insulation layer of the motor. The fire resistance is poor, and the use of fire resistant cables is strictly prohibited.
