Product Description:

1. Introduction:

 

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

 

2. Main features of Mica Parts:

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.

Q:Brass is not an insulating material?
Brass is not insulating material. On the contrary is the brass is conductive material. Brass texture hard, can not bend. No copper flexibility is good, so brass can only do a fixed copper conductive use.
Q:What insulating materials do you need for power tools?
Insulation system of power tools can be divided into basic insulation, additional insulation, reinforced insulation, double insulation. Basic insulation: enameled wire and iron core between the insulating paper (paper for the green paper or DMD insulation paper) is the basic insulation, Withstand voltage is 1250V;
Q:The electrical equipment in the classroom which uses insulating material
Insulation material characteristics: chemical resistance with gloss, some transparent or translucent most of the good insulator light weight and strong processing can be easily mass production, cheap and wide range of uses, utility, easy to color, some high temperature
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.
Q:What is the thermal aging and electrical aging of insulating materials?
Electrical aging more common in high-voltage electrical appliances, the main mechanism is the occurrence of partial discharge of insulating material under high pressure, resulting in strong oxidant ozone. Ozone is easy to cause ozone cracking of the material. Partial discharge will produce nitrogen oxides, which combine with the moisture to produce nitric acid, corrosion of insulating materials; partial discharge of high-speed charged particles bombardment of insulating material molecules, will promote its ionization, fission and damage; in addition to local discharge will make dielectric loss Increased, local heat of the material, resulting in heat aging.
Q:What is the electrical performance of insulating materials
Such as the rated voltage, current, active power, reactive power, resistance, capacitance, inductance, conductance; semiconductor is famous, DC magnification, AC magnification, rectified current, reverse breakdown voltage, forward voltage , The junction voltage, the noise figure, the characteristic frequency, the cut-off frequency, the dissipation power ... the IC is also very large, the maximum working voltage, the op amp's pendulum speed, the bandwidth, the distortion coefficient, the ADC conversion rate, , The resolution of plastic in the field of electrical applications is extremely extensive, its role is mainly two aspects, one as electrical insulation materials, two for the mechanical structure of materials. These materials are used in the field of electrical engineering, mainly in the electrical, electrical and electrical industries.
Q:The role and definition of insulating materials
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:Wear-resistant, high temperature, insulation materials which
Epoxy, temperature from 100-400 degrees, processing more convenient. Ceramic is the best and cheap.
Q:What are the electrical insulation materials
Many types of insulating materials, can be divided into gas, liquid, solid three categories. Commonly used gas insulation materials are air, nitrogen, sulfur hexafluoride and so on. Liquid insulation materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, dodecyl benzene, polyisobutylene, isopropyl biphenyl, diaryl ethane, etc.) two categories. Solid insulation materials can be divided into organic, inorganic two categories. Organic solid insulation materials include insulating varnishes, insulating glue, insulating paper, insulating fiber products, plastic, rubber, lacquered lacquers and insulating impregnated fiber products, electrical thin films, composite products and adhesive tape, electrical laminates and so on. Inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, solid insulation material variety, but also the most important. Different electrical equipment requirements for the performance of insulating materials are focused. High-voltage electrical equipment such as high-voltage motors, high-voltage cables and other insulation materials require high breakdown strength and low dielectric loss.
Q:What are the gas insulation materials?
In addition to air, nitrogen, carbon dioxide and sulfur hexafluoride gas, there are other gases used for insulation. CCl2F2 (freon-12) was used as an insulating in certain high-energy physical devices. CCl2F2 breakdown strength and SF6 similar, but because of its high liquefaction temperature, and the spark will make CCl2F2 precipitation of carbon particles, therefore, has been replaced by SF6. In hydrogen-cooled generators, hydrogen is also used as insulation in addition to cooling media.
