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 difference between insulation and pressure?
Insulation resistance is measured with an insulation resistance tester (10000V or less) or an insulation shaking table (2500V or less). Since the test voltage is low, many insulation defects are not easily found; the withstand voltage test test voltage is high and the high pressure equipment is easily found Insulation defects;
Q:What type of enameled wire and insulation material is used for the compressor
Enclosed wire and insulation materials for fully enclosed compressors: 1) Refrigerant R12, enameled wire with high strength polyester QZ, insulated with 6400 epoxy resin Insulation H34-4, Polyurethane film for insulating material Green paper (DMD ) Insulation paper; 2) refrigerant R22 and R502, with QF, QXY polyamide imide enameled wire, insulation treatment with EIU epoxy modified impregnated varnish, insulating material with polyimide film and poly Fiber composite foil, F-class insulation DMD insulation paper.
Q:What is the thermal aging and electrical aging of insulating materials?
Environmental aging, also known as atmospheric aging, is due to ultraviolet light, ozone, salt spray, acid and other factors caused by pollution of chemical aging, which is the main reason for ultraviolet light. Thermal aging more common in low-voltage electrical appliances, the mechanism is under the action of temperature, the insulating material in some volatile components escape, the internal components of oxidative cracking, thermal cracking, hydrolysis, molecular chain polymerization and other chemical changes, and gradually lose insulation properties.
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 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:Brass is not an insulating material?
Brass is a particularly good conductive material and is a good material for wearing heat
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:The role and definition of insulating materials
Electrical strength is the breakdown of the voltage between the voltage and the two electrodes subjected to the applied voltage under the specified conditions, that is, the breakdown voltage per unit thickness. For insulating materials, the general breakdown voltage, electrical strength of the value of the higher the better. 4, tensile strength: in the tensile test, the sample to withstand the maximum tensile stress. It is the most widely used and tested test of the mechanical properties of insulating materials. 5, Flammability: refers to the insulation material in contact with the flame to resist combustion or leave the flame to prevent the ability to continue to burn. With the increasing use of insulating materials, its flammability requirements are more important, people through various means to improve and improve the insulation
Q:What are the electrical insulation materials
Insulation board: plastic plate is made of plastic sheet, plastic for the synthesis of polymer compounds, can be free to change the body style. Plastic is the use of monomer raw materials to synthesis or condensation reaction polymerization of materials, synthetic resin and filler, plasticizers, stabilizers, lubricants, colorants and other additives, and its main component is synthetic resin.
Q:What insulating materials are used for transformers
With the largest number of cardboard, as well as laminated wood, insulating paper, transformer oil, large oil-immersed transformers are mostly oil - paper insulation.
