1. Introductions:

Mica is a rigid substrate able to withstand very high temperatures and are suited for applications up to 500°F (260°C). Mica heating elementsoffer several distinct advantages over other flexible heater technologies, including extremely low leakage, lower material costs, and higher operating temperatures. Our mica heating element is made by detail order requirments.

Mica plate is made of mica paper with high performance organic silicon resin. After heating and pressing, the mica plate can be made into rigid or flexible insulating plates. The mica content is about 90% and the organic silicon resin content is 10%.

2. Main features of Mica Parts:

Rigid mica plates are featured with high strength, good performance, less smoke, less odor etc. This series mica plates are used mainly in household appliances (toaster ovens, microwave ovens, warm air blowers, hair dryers, electric iron etc.), metallurgy (such as line frequency furnaces, medium frequency furnaces, electric arc furnace, etc.), medical equipment and other industries, used as the heating support, lining plate and partition plate of the electric appliances described above.

3. Applications:

Typical applications of mica heating elements are air heaters, enclosure systems, food service equipment, process and packaging equipment.

FAQ

We have organized several common questions for our clients,may help you sincerely：

--------What is the use of mica parts?

Mica laminate and washers made of our own high quality mica plates are used for home appliances, electro-magnets, micro-sensitive control gear etc

---------Which type of mica parts we can produce?

1. Rigid mica parts or Flexible mica parts

2. Muscovite mica parts or phlogopite mica parts

3. Thin mica parts or thick mica parts

4. All the special sized mica parts need drawing.

----------what advantages of mica parts?

1. Good high voltage insulation materials

2. Do not easily break up

3. Easily produce special size

Q: The electrical equipment in the classroom which uses insulating material: The use of insulating materials in the classroom electrical equipment: wires, screwdrivers, pliers, sockets, switches, lampholders, lamps, bulbs, motors.

Q: What is the 8 ° C rule for insulating materials?: Insulation material 8 ℃ rules: Insulation material used in the temperature exceeds the limit temperature, the insulation material will quickly deteriorate, the service life will be greatly reduced.

Q: There are a lot of online about this, but still do not understand. If the insulation resistance is high enough, hit the pressure should also be qualified ah. There is insulation test itself when the current flow is not large, because the rock table resistance is great. But hit the pressure, I do not know is not a direct high pressure drop in the test product above, there is no great resistance to interference?: Insulation test Because the test voltage is low, it is not easy to damage the equipment under test. The voltage test is easy to damage the equipment under pressure when the test voltage is high. In some cases, although the withstand voltage test is passed, Causing damage, the test staff will have to use low-voltage insulation test, test the pressure test after the test equipment insulation. Under normal circumstances, insulation resistance qualified, withstand voltage test will be adopted.

Q: Brass is not an insulating material?: Of course not, brass is still relatively good conductor blanket, and also has good thermal conductivity

Q: What type of enameled wire and insulation material is used for the compressor: Motor insulation class The insulation class is divided according to the permissible limit temperature of the insulation material used for the motor. There are Y, A, E, B, F, H, C and several other levels, the allowable limit temperature at all levels as shown in the table below. The so-called permissible limit temperature refers to the permissible maximum operating temperature of the motor insulation material, which reflects the heat resistance of the insulating material. Insulation material is divided into Y grade, A grade, grade E, grade B, grade F, grade H, grade C, permissible temperature (℃) 90,105,120,130,155,180, 180 ℃ or higher.

Q: Insulation material and the definition of the role of the best professional insulation materials website for my reference: Its resistivity is very high, usually in the range of 10 ^ 9 ~ 10 ^ 22Ω · m. Commonly used insulating materials according to their different chemical properties, can be divided into inorganic insulating materials, organic insulating materials and mixed insulation materials. Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on,

Q: What are the gas insulation materials?: The relative breakdown strength of air (at air 1) at the standard pressure (101335Pa) is as follows: nitrogen, 1; hydrogen, 0.5; carbon dioxide, 0.9; sulfur hexafluoride, 2.5; freon-12,2.7 The

Q: What is the DMD insulation material?: These small mirrors are approximately 16 or 14 microns in size and are usually made up of an array of up to 50 to 2 million, with a gap between the mirrors of 1 micron and a mirror rotating with an aluminum hinge as a rotation axis 10- 12 degrees, can be used repeatedly 1 trillion, life test shows that in accordance with the usual use can be used for 100,000 hours. Its opening and closing control is through the mirror stop when the damping effect of the spring contact near the mirror, gradually reduce the way the additional voltage to achieve. DMD chip has been upgraded, the original chip on the microscope size of 16 microns, flip angle of 10 degrees, the current DMD micrometer size of 14 microns, flip 12 degrees, support 4K resolution chip has also been formed, the chip size of about 1.38 Inch.

Q: What are the commonly used insulating materials?: Mainly used for motor, electrical winding insulation, switch the bottom plate and insulators, etc. Organic insulation materials are: shellac, resin, rubber, cotton yarn, paper, linen, rayon,

Q: What insulating material is best `?: The earliest use of insulating materials is cotton, silk, mica, rubber and other natural products .20 century 30 years later, the rapid development of synthetic insulation materials, a variety of synthetic resin, plastic, etc. used in the field of electrical engineering to manufacture motor and high and low pressure Electrical appliances, so that the capacity of electrical products continue to expand, the volume gradually reduced, so as to promote the development of electrical and electronic technology.
