Mica board to white mica paper, gold mica paper as raw materials, is an insulating material, through the high temperature silicone resin bonding, baking, and pressed into, mica board applications are still quite wide, because of its high temperature resistance and excellent performance of the edge, and when heated with little smoke, and no odor, so in the household appliances are widely used, such as: iron, hair dryer, or microwave ovens, water heater and so on. So what is the price of mica board? Mica board manufacturers and what are they?

The key role played by mica board in high temperature insulation, how to make mica board, how to work?
We want to first introduce the production method of mica plate heat. Used in the mica heating board within the electric wire is the first electric alloy material pressed into as little as a few millimeters of thin plate, and then choose to corrode or laser cutting method to let it molding, and then choose to glue the electric wire in the mica substrate, through the high-strength die-casting molding. Electric heating wire is characterized by high temperature, power density can be made large.
2. How does the mica board work after heating?
1). Electric heating wire mica electric heating plate because of the selection of adhesive process, metal heating wire and mica plate in the heating coefficient of expansion is not the same and simple delamination, together with the high temperature state of the glue volatilization off in the future will be simple to fall, the electric heating wire intertwined with a simple short-circuit.
2)Because of the specific gluing process of the electric heating wire, so that the glue at high temperature will become powder and volatile announced an unpleasant odor, and the smell of the detected formaldehyde-rich.
3)The electric wire in the corner of the local current is too large, the temperature is too high (up to 500-700 degrees above), simple damage and risk formation, in some manufacturers have been presented to the mica substrate burned out a black hole in the situation, and even the risk of fire.
4) Because the electric wire is a wire heating, so it is difficult to ensure the uniformity of heating, the temperature of the outer surface of the electric wire reaches 500 degrees, so the electric wire mica heating plate will be used for a period of time in the mica plate appearance of the baked wire black marks, affecting the beautiful. If the appearance of mica long time in the kind of high temperature, can affect the use of mica substrate life.
5)Mica heating plate start current is large, usually in the rated current of 3-4 times, in the junction box local also want to heat, so the electric heating plate in the local out of the wire box simply show the fire discharge phenomenon, and even in some supporting manufacturers of the products presented in the junction box at the burning of a big black hole in the phenomenon.
6) mica heating plate selection is a series circuit design, if a point of damage, then the whole heater on the scrap, and our products selection is a full parallel circuit design, if the presentation of extreme conditions, a hot piece even if the damage does not affect the other hot pieces of the work, the consumer also does not feel.
8)Safety. If the polar condition, the electric heating wire will first burn a large hole in the mica layer, and will always press the super-rated power energized heating, until the electric heating wire completely melted, the process is capable of igniting the wood floor, carpets and other flammable materials. And extreme conditions, such as the use of non-normal voltage, electric heating film mica heating plate will be a personal disconnection and the formation of power loss, or hot pieces of self-destruction and no longer heat, will not lead to fire and other risks.
The above is about the mica board manufacturers recommended and mica board heat is how to work the introduction, because of its bonding properties and high temperature characteristics, the production of a lot of home appliances and office equipment to facilitate our lives, to our lives as well as the work to bring great convenience, we are in the purchase of the time to shop, to shop around, as far as possible, choose to the cost-effective mica board, so that the cost can save money. You can save cost. The above manufacturer price is for reference only, the actual price is still with the manufacturer to further communication based!
