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 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:

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 linefrequency 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.

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. , including extremely low leakage, lower material costs, and higher operating temperatures. Our mica heating element is made by detail order requirments.

3. Easily produce special size

Q: What is the electrical performance of insulating materials: Insulation material electrical performance mainly refers to: good dielectric properties, high insulation resistance and compressive strength. Do not occur leakage, creeping or breakdown and other accidents. Good heat resistance performance in the long-term heating state no significant change in performance. Good thermal conductivity, moisture resistance and mildew resistance.

Q: Insulation material and the definition of the role of the best professional insulation materials website for my reference: The main indicators affect the performance of insulating materials 1, insulation resistance, resistivity: resistance is the reciprocal of conductance, the resistivity is the resistance per unit volume. The smaller the conductivity of the material, the greater the resistance, the reciprocal relationship between the two, for the insulation material, always want the resistivity as high as possible. 2, the relative dielectric constant and dielectric loss tangent:

Q: Who knows what are the ability of 1300 degrees above the high temperature, insulation materials?: High temperature resistant materials include refractory and heat resistant materials, inorganic compounds, and polymer materials. Refractory material usually refers to the resistance of 1580 ℃ above the temperature of inorganic materials. They are built kilns, combustion chambers and other building materials that require high temperatures. General use of quartz sand, clay, magnesite, dolomite as raw materials and made, such as refractory cement, magnesia and so on. Broadly speaking, inorganic refractory, heat-resistant materials refers to the high hardness of these compounds, good brittleness, good chemical resistance, and the melting point of 1500 or more. Mainly divided into metal and non-metallic compounds and non-metallic compounds.

Q: What insulating materials are used for high frequency transformers?: In the production process of high-frequency transformers, insulation is a crucial step, this time you need to use a kind of insulation called the water, that is, paint. A class of artificial paint, shiny, good sticky. It is a paint that does not contain coloring matter. When applied to the substrate, it can form a transparent film with protection, decoration or special properties.

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 main purpose of insulating materials?: As the insulating material has a certain degree of insulation strength, a variety of electrical equipment, all kinds of safety equipment (electrical pliers, test pen, insulated gloves, insulation rods, etc.), a variety of electrical materials, factories are required to allow a certain voltage, For the rated voltage. The voltage to be used shall not exceed its rated voltage value in order to avoid accidents.

Q: What is the DMD insulation material?: DMD insulating paper, the product is a layer of polyester film coated with adhesive, one side for the polyester fiber non-woven composite, calendering from a composite insulation products, referred to as DMD.

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 thermal aging and electrical aging of insulating materials?: Insulation materials in electrical equipment during the operation, due to the long-term effects of various factors, there will be a series of irreversible physical and chemical changes, resulting in its electrical performance and mechanical properties decline, commonly known as aging. There are many factors that affect the aging of insulating materials. The main aging forms are environmental aging, heat aging and electrical aging.

Q: What insulating material is best `?: Liquid insulation material, also known as insulating oil. Fill the internal or inter-electrode gap between the solid material to improve its dielectric properties and improve the cooling capacity of the equipment. Liquid insulation material high breakdown strength, dielectric loss tangent (tgσ) small, insulation resistance High specific dielectric constant, in addition, also has excellent physical and chemical properties, such as high gasification temperature, high flash point, low freezing point, thermal conductivity, thermal stability, in the electric field under the suction Small and so on.
