Mica Heaters Introduction:
The mica heater features an etched foil element encased between layers of mica. This heater is relatively rigid and can be used both as a securely and uniformly clamped heater for reliable support and effective heat transfer, as well as a standalone heater. The mica heating plate operates at high temperatures and watt densities, offering rapid heat-up and ease of design.
High-temperature mica heaters are utilized across various industries, from semiconductor manufacturing to food service. Their very uniform temperature distribution across the heating elements ensures precise heat transfer.
Technical Parameters:
1.Mica heaters can withstand very high temperature ranges (up to 600°C).
2.Mica heaters are very economical due to the low cost of materials.
3.Mica heaters can be effectively configured in a wide range of watt densities (10W/cm²).
4.Mica heaters can be manufactured into any shape.
5.Mica heaters can be easily clamped onto flat surfaces that require uniform heating, it can also be used on curved surfaces.
6.Mica heaters can be integrated with sensors, limiters, and thermal fuses to allow control and operation in a wide range of temperatures.
Applications:
1. Food Service Equipment (Microwave oven, oven)
2. Mica heater for Space heater
3. Greenhouse heating systems (Mica heaters are used in greenhouse heating systems for plant growth and temperature control)
Q1: What is the maximum temperature for a mica heater?
A: Mica heaters have a temperature range up to 600°C.
Q2: What shapes can mica heating plates be made into?
A：Mica heating plates can be made into various shapes, such as plate, sheet, cylindrical, conical, tubular, and ring shapes.
Q3: What is the conductor of the Mica heater?
A: The commonly used metal is nickel-chromium alloy, the metal is insulated with mica on both sides.
Q4: How is a mica heater typically assembled?
A: It can generate heat on both sides and can be clamped between the heated products or fixed onto the heated products using mechanical methods.
Q5: What are the wire soldering methods?
A: Rivet welding or solder paste welding.
Q6: Are mica heaters safe?
A: Mica minimizes the risk of electrical shocks due to its insulating properties. Additionally, mica heaters maintain a relatively low surface temperature, reducing the likelihood of accidental burns.
Q7: Can mica heaters be used in damp or wet conditions?
A: Mica heaters can operate in damp or wet environments, but they are not waterproof. Direct exposure to water can lead to short circuits or other electrical issues. Therefore, it is essential to ensure the heater is protected from direct contact with water.
Q8: Why does mica sheet use in a toaster?
A: It is a very good electrical insulator that can be punched like cardboard and withstand high temperatures.
Q9: Can mica heater be kept on for extended periods?
A: Mica heater as a high-efficiency, energy-saving, and environmentally friendly electric heating material, can be kept on for extended periods. However, it is important to pay attention to safety issues such as grounding and installation location. Regular maintenance is necessary to clean the plates and avoid breakage and scratches on the mica sheets.
Q10: What are the performance parameters that Mica heater?
A: Insulation resistance: ≥100 MΩ. Voltage resistance: 1500V/1min.
Temperature resistance: 600°C. Power deviation range: ±5%.
