Microwave-prepared aerogels felt can reduce the risk through intelligent design and meet the production requirements of high-quality products. The complete set of equipments is fully automated, and all monitoring equipment is centrally controlled, and a continuous production process can be realized. The production requirement of 180 square meters per hour can be achieved. The annual output exceeds 10,000 square meters. Continuous production, without stopping, has produced several units. The aerogel is prepared by the microwave method. The microwave aerogel supporting equipment production line is equipped with a rewinding and unwinding machine and metal Detection, feed detection, alcohol spraying, microwave curing gel, leak detection, alcohol detection, and other equipment, the entire process is monitored by LCD touch control, to ensure that continuous production capacity is increased. It has changed the bottleneck of the traditional aerogel preparation process, greatly improved the production capacity of the enterprise, provided a professional microwave heating technology design scheme for aerogel insulation felt on the road of industrial production and took the lead in integrating sophisticated automatic control systems and intelligent systems Microwave curing gel equipment production line applied to aerogel insulation blanket.
Aerogel felt is a flexible thermal insulation materials that uses silica aerogel as the primary material and is compounded with reinforcing fibers, such as glass fibers and pre-oxidized fibers, through a unique process. Aerogel felt it is currently a solid thermal insulation material with low thermal conductivity in the temperature range of about 400℃. The thermal conductivity of the high-temperature zone at 400-1000℃ is much higher than that of the micro-nano thermal insulation series aerogel and traditional materials. It is soft, comfortable to cut, low density, inorganic fireproof, overall hydrophobic, green, and environmentally friendly. It can replace glass fiber products, asbestos insulation felt, silicate fiber products, and other traditional flexible insulation materials that are not environmentally friendly and have poor insulation performance.
Microwave heating basically heats objects that are too thick inside and outside, unless electromagnetic waves do not penetrate or the penetration depth is not enough. This heating method is compared with heating methods such as hot air, gas, steam, electric heating, and far-infrared. The speeds is much faster, usually several times to tens of times or even higher. High heating efficiency, energy-saving, and energy saving. Because microwave heating is the result of electromagnetic waves directly interacting with material molecules, unlike conventional heat radiation or heat conduction methods, a part of the heat energy will be wasted uselessly. The loss of microwave propagation in the air is minimal (in short distances). ), the energy loss mainly concentrates on the material volume, and the microwave power conversion efficiency is high, so it can save power consumption and improve economic benefits. Heat evenly. The principles of microwave heating determines that the temperature rise process of the material is different from the conventional method. The temperature distribution of the latter is external heat and internal cooling, while the microwave heating method keeps the temperature difference between the inside and the outside at a reasonably low level, sometimes even causing the internal temperature to be higher than the surface—the temperature situation.
