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%.

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.

3. Main features of Mica Parts:

Rigid mica plates are featured with high strength, good performance, less smoke, less odor etc.

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:What kind of insulation is the insulating: Insulation is the core technology of aluminum substrate. Currently on the market most of the aluminum substrate insulation layer using epoxy resin, the advantages of this type of insulation is: good adhesion; drawback is: thermal resistance, dielectric strength is limited, it is difficult to meet the safety requirements. Such aluminum substrates are only suitable for low power density applications. High-end aluminum substrate insulation layer is generally composed of high thermal conductivity and high insulation ceramic powder filled with special polymer composition.

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: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 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 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 are the commonly used insulating materials?: Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on, which can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials.

Q:What is the DMD insulation material?: DMD (Dacron / Mylar / Dacron) full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials.

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:Brass is not an insulating material?: Brass is a particularly good conductive material and is a good material for wearing heat

Q:What insulating materials are used for transformers: Some of the transformer plants in the United States, such as FPT in Virginia, have developed a NOMEX? Aromatic Polyamide using DuPont as a primary insulated dry-type transformer. FPT products are available in two models: FB type 180 ℃ (H level) of the insulation system. FH type 220 ℃ (C level) of the insulation system, the coil temperature rise were 115K (China 125K) and 150K. Its low-voltage coil is foil-type or multi-layer and laminated, and NOMEX? is used for both turn insulation and interlayer insulation. The high-pressure coil is a cake, and the wire is wrapped in NOMEX? paper. The barcakes do not have a conventional stay and a pad, and the comb is used to reduce the maximum voltage of the cake by half. The high-voltage coil of the axial short-circuit resistance, but increased the coil winding system and manufacturing time. High and low voltage coil for nesting, enhanced mechanical strength.

Q:What insulating material is used for high voltage cables: YJLV23 Aluminum core XLPE insulated steel tape armored PVC sheathed power cable YJV32 copper core XLPE insulated fine steel wire armored PVC sheathed power cable indoor, tunnel, cable trench, shaft or buried
