Product Description:

1. Introductions:

Mica plate is made of mica paper with highperformance 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%.

Mica is a rigid substrate able to withstand very high temperatures and are suited for applications up to 500°F (260°C). Mica heating elements offer 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.

2. Applications:

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

 

 3. 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.

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 insulating materials do you need for power tools?
Reinforced insulation: the voltage between the live parts and the accessible housing is 3750V, such as the voltage between the brush and the cover surface; double insulation: basic insulation + additional insulation. Main insulating material: green paper or DMD Insulation paper for basic insulation; shaft insulation and plastic housing for additional insulation; rotor insulation end plate, stator insulation end plate, used to control the creepage distance and electrical clearance; brush grip bakelite powder, used to strengthen the insulation; other parts (Power plugs, commutators, switches, etc.) These are pressure requirements.
Q:What is the insulating material in the middle of the connecting wire?
With a transparent tape isolation, with hot melt adhesive fixed thread, with heat shrink tube insulation, a lot of ways ah.
Q:What insulating material is best `?
Gas insulation material has a high ionization field strength and breakdown field strength, after the breakdown can quickly restore insulation performance, chemical stability, non-combustible, non-explosive, non-aging, non-corrosive, easy to discharge decomposition, and greater heat capacity , The thermal conductivity, and the flowability are all. The air is the most widely used gas insulating material, for example, between the overhead wires of the AC and DC transmission lines, and the overhead wires are insulated by air. The high voltage standard capacitors also use gas insulating media (SF6) .SF6 is also used in the manufacture of high-voltage circuit breakers, metal-enclosed combination of electrical appliances, gas-insulated transmission pipeline cables and gas-insulated transformers, etc., the use of high-pressure nitrogen or carbon dioxide.
Q:What are the electrical insulation materials
Insulation material is electrical insulation material. According to the national standard GB2900.5 provides the definition of insulating material is: "used to make the device in the electrical insulation of the material." That is, to prevent the current through the material. Its resistivity is very high, usually in the range of 10 ^ 9 ~ 10 ^ 22Ω · m. As in the motor, the insulating material around the conductor isolates the turns and isolates it from the grounded stator core to ensure safe operation of the motor.
Q:What type of enameled wire and insulation material is used for the compressor
Small and medium-sized closed, semi-enclosed refrigeration compressors are used for the specific enameled wire specifically (QF) series.
Q:Wear-resistant, high temperature, insulation materials which
Epoxy, temperature from 100-400 degrees, processing more convenient. Ceramic is the best and cheap.
Q:What is the 8 ° C rule for insulating materials?
Such as A-class insulation material limit working temperature of 105 ℃, when the ultimate operating temperature of 8 ℃, its life will be reduced by about half, which is 8 ℃ thermal deterioration rules.
Q:What insulating materials are used for high frequency transformers?
Can be brush, can be sprayed, can be baked Here is the main raw material for ice making. Selection of industrial products. All around the paint factory production. General high-frequency transformer insulation materials used by the scope and form are divided into: impregnated paint, covering paint, silicon steel paint, anti-corona paint four.
Q:What is the main purpose of insulating materials?
Tensile strength: The cross-sectional area of the insulating material can withstand tensile forces, such as glass per square centimeter cross-sectional area can withstand the resistance of 1400 Newton.
