Mica sheet

Mica sheet

Mica sheet can be composed of muscovite or phlogopite type. These are two types of mica that can be used in the field of industry.

Muscovite mica sheet is available in dry and soft form, which if we want to express the heat tolerance of this product based on its softness and hardness is as follows:

The maximum temperature it can withstand is up to 1000 degrees Celsius.
In soft mica sheet for high use, the value is 900 to 650 degrees Celsius.
In hard mica sheet for high use, the value is set to 700 to 500 degrees Celsius.
Mica sheet is produced in two types. These two types are:

Mica sheet phlogopit
Muscovite sheet
The most important benefits of these two types of mica include:

It is non-combustible.
It is non-toxic and natural.
It has a long life and low weight.
Maximum heat tolerance up to 1000 degrees Celsius and for high use up to 900 degrees Celsius, which of course is based on the amount of compounds in this sheet.
It has high heat storage and low thermal conductivity.
Has the ability to control the pressures on the parts.
Some waves can pass through the mica sheet.
It has very high mechanical strength and considerable tensile strength.
Has a special dielectric property that has increased the resistance to electric arc and electrical stability.
Works well in environments with oil, water, most alkalis, acids and solutions.
In this part of the article, we want to mention some applications of refractory sheet based on softness and hardness, as well as its type, which is related to the type of phlogopite and muscovite.

Application of soft mica sheet based on the type of phlogopite or muscovite, including:

Primer for heating furnaces
Construction of expansion joints to protect the furnace walls during expansion or contraction of the coating
Thermal insulation of industrial and domestic stoves
Electrical insulation of parts
Insulation pads in the field of automotive
Insulation of parts in the field of aerospace, steel and casting
The application of hard mica sheet depending on the type of phlogopite or muscovite is as follows:

Insulation of heaters, hair dryers, toasters or appliances that generate heat in a short time
Is in charge.

It has thermal floor insulation.
It has induction furnace cover for electrical and thermal insulation at the same time.
