HebeiThe purpose and characteristics of perlite board insulation board drying equipment:

Jinan LongtuoBrand MicrowavePerlite board dryer,Specifically used in insulation boards, rock wool boards, cement boards, drying and forming,Perlite is a lightweight and multifunctional new material, which has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption capacity, and is non-toxic, odorless, fireproof, and sound-absorbing. It is widely used in various industrial sectors. Perlite fireproof board is a new type of fireproof door core filling material made by expanding perlite, pre embedded skeleton, and using suitable adhesives as binders, and applying pressure.

Characteristics of industrial microwave dryer for perlite board:

1. Fast drying speed, high efficiency, and good product color. According to data, microwave drying speed is 20 to 30 times faster than commonly used convection drying speed.

2. Dry evenly, without deformation or cracking. Due to the simultaneous action of microwaves on the inner and outer parts of the material, the heat is evenly generated. Therefore, materials treated with microwaves are dried uniformly and thoroughly, improving product quality. The surface will not harden, improving toughness, ensuring no cracking, deformation, discoloration, and adjustable bending.

3. Efficient and energy-saving. Using far-infrared and steam energy for material drying has an energy utilization rate of less than 50%, while using microwave as energy can achieve a utilization rate of over 75%, reducing energy consumption by more than 25% compared to far-infrared and steam drying. Perlite insulation board can be dried using microwave drying in only 10-20 minutes.

The principle of microwave heating is that microwaves are electromagnetic waves with frequencies ranging from 300MHz to 300GMHz, and their direction and magnitude change periodically over time. The process of microwave heating involves the direct interaction between microwaves and materials, converting ultra-high frequency electromagnetic waves into thermal energy. Water is a substance that strongly absorbs microwaves, and the water molecules in the material are polar molecules. Under the action of microwaves, their polarity orientation changes with the external electromagnetic field, causing rapid friction and collision of molecules, resulting in a series of processes such as heating and puffing of the material to achieve the purpose of microwave heating.

Perlite board, fireproof insulation door core board microwave drying equipment is a new type of specialized drying equipment developed by Longtuo Microwave Equipment Co., Ltd. to address the poor thermal conductivity and insulation properties of perlite fireproof board, which cannot be uniformly dried using conventional drying methods. The equipment uses high-frequency electromagnetic waves with a frequency of 2450MHz to penetrate and heat perlite boards, avoiding the thermal conductivity process of perlite and achieving rapid heating and evaporation of moisture inside the board, thus achieving the purpose of drying perlite fireproof door core boards.
