What is the DMD insulation material?
DMD insulation paper has good mechanical strength, dielectric properties and high heat resistance (B and F), is Y series motor stereotypes insulation material, can be used as small and medium-sized motor slot insulation, turn Insulation, liner insulation and transformer insulation. Part of the thickness of the product has been widely sold to Europe and the United States and Southeast Asia market.
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.
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.
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.
