Types of Infrared Heating Boards

Infrared heating boards are flat devices that produce heat by emitting infrared radiation. They are commonly made with carbon materials, ceramics, metal alloys, crystal glass, or graphite, each with unique properties that offer distinct benefits.

• Carbon Fiber Infrared Heating Board:

  This ultrathin electric heating panel is powered by electrical current, which heats the carbon fibers, emitting warm infrared rays. Carbon fiber boards generally heat up quickly, distribute warmth evenly, and are known for their energy efficiency. They are flexible and can be curved or shaped to manufacture nonflat heating elements. Yet, they are vulnerable to high humidity, which can lead to reduced performance or damage over time.

• Ceramic Infrared Heating Board:

  Ceramic infrared heaters come in several forms, such as ceramic plates and tiles. They are produced through a firing process. When heated, they release infrared radiation. These types of heaters can achieve very high temperatures in a short amount of time. Compared to other materials, ceramic has high resistance to heat and high durability. Hence, infrared heating boards made of ceramics can withstand extreme temperatures without deforming. Generally, they can withstand high humidity environments.

• Metal Alloys Infrared Heating Board:

  Some metal alloys, like stainless steel, are categorized as infrared heating panels. The method of making those products often involves molding metal alloys into desired shapes. The metal alloys heat up rapidly when electricity passes through them. They have high durability against corrosion and can last in humid and dry environments alike.

• Crystal Glass Infrared Heating Board:

  Those boards are manufactured from crystal glass. They are coupled with electrical elements. Electrical current heats the glass, which radiates infrared heat. Not only do these boards dissipate heat, but they also can be part of a gorgeous home decoration. Their main downsides are related to high humidity environments and fragility. Even though they are more durable than traditional glass, they are still sensitive to sharp objects and abrupt temperature changes.

• Graphite Infrared Heating Board:

  Graphite is a unique material because it has chemical and physical longevity. Its high temperature resistance makes it radiant more heat for a longer period of time. Thanks to its high thermal conductivity, heating elements made of graphite disperse heat evenly. This feature allows them to have more localized heating.

• Operating temperature: The operating temperature of infrared heating boards can vary by design. Infrared heating boards can maintain surface temperatures between 200 and 700 degrees Celsius. Higher temperatures may affect the life span of the board.
• Voltage and Power: Infrared heating board power ranges from small units measured in watts to larger ones in kilowatts. The power of the heating board will affect the heating speed and intensity. For example, a small board might have 100 watts, and a large one might have up to 5,000 watts. The operating voltage specifications are designed for particular voltage requirements. For instance, a 220V board has a voltage of 10,000 watts.

Maintenance

• Clean: Using a dry cloth to clean the dust on the heating board, no water or moisture is used, which may prevent electrical hazards.
• Avoid sudden temperature changes: Prevent sudden temperature changes, such as pouring cold water on the hot heating board or placing it in a cold environment, which may cause the heating board to crack.
• Avoid direct contact with flammable materials: Avoid direct contact with flammable materials, such as plastic, fabric, etc., which could catch fire or harm the heating board.
• Heat sink and fan cleaning: If the infrared heating board has a heat sink and fan, keeping them clean is critical. Cleaning the dust from the heat sink and fan improves the cooling efficiency.
• Repair timely: If it breaks, it needs to be fixed in time. Damaged parts include cracks, burns, etc., which may affect the use and safety of heating.

Application Scenarios

• Curing and Drying

  Infrared heating boards are widely used for curing and drying applications. They can quickly and evenly dry materials like coatings and paints, adhesives, textiles, wood, and paper products. The energy-efficient infrared boards reduce drying time and improve production efficiency.

• Plastic and Composite Molding

  The molding of plastics and composites relies heavily on infrared heating. Thermoplastics and thermosets are heated by infrared boards until they are pliable. The materials are then formed into the desired shapes using molds. Infrared heating ensures uniform heating and reduces cycle times in molding operations.

• Food Industry Applications

  Infrared heating boards offer various applications in the food sector. Infrared therapy is used by the majority of food processing firms to assist with drying, cooking, defrosting, and sterilization. Examples include commercial food dehydration equipment like dried fruit making machines and beef jerky making machines. One important characteristic of infrared heating is that it doesn't heat the air surrounding the item. This results in a lower energy cost and a quicker production rate.

• Textile Industry Applications

  In the textile sector, infrared heating boards are used for applications including drying, heating, and shrinkage of fabrics. For instance, applying finishes to textile goods requires the use of infrared drying tunnels. The textiles are continuously traversed by infrared radiators in the tunnels till they are dry. Infrared heating may quickly and effectively dry cotton, polyester, and nylon textiles. Shrinkage may be controlled by infrared heat treatment, which also ensures the stability of the fabric.

• Glass and Ceramics Firing

  Making glass and ceramics involves applying heat to infrared boards. For kiln firing and tempering, ceramic components, such as tiles, sanitary ware, and tableware, require preheating. Infrared heating guarantees the components are evenly heated, which improves their stability and durability. To raise the temperature of glass components like bottles, jars, and containers, infrared heating is also employed to refine glass. The items are up to temperature, which improves their mechanical characteristics, thanks to this method.
