Perlite has long been used as building insulation materials in people cured mindset is, indeed, perlite insulation materials synonymous. Expanded perlite from the original cement to glass beads, are to take advantage of the low thermal conductivity of perlite pore. But perlite is similar to the large surface area of the activated carbon adsorption, sound insulation and noise reduction performance. These physical and chemical properties to the the perlite uses a wide door open.
According to the latest research findings, perlite can be applied to the military. In the world, can use the microwave radar, infrared radar or other electromagnetic waves radar and acoustic detection system shield absorbing materials has been the general concern of the countries in the military field. Infrared reflective material can be used in such fields as aviation, construction materials, vehicles, weapons. The perlite product density is small, its surface the metalization process that can replace the greater density of the metal powder is applied to the manufacture of the materials on the electromagnetic wave absorption (RAM) or electromagnetic shielding (ENI).
    In recent years, domestic chemical coating perlite research, found that can change its photoelectric properties and thermal properties, especially nickel-cobalt plating can be improved after the absorption of electromagnetic waves and near-infrared reflectance, perlite has been applied to the military the security coating which, just as civilian technology to strengthen the performance of the thermal insulation coatings. Activation method using silver nitrate in the perlite surface covering the NI-C0-P, can be used for to absorb electromagnetic shielding and microwave absorption civilian aspects can be manufactured into anti-electromagnetic radiation materials, and military aspects of radar absorbing stealth materials can be manufactured. The electroless plating method, plating the surface of the perlite glassy microbeads prepare low density of the magnetic raw metal C0 layer a magnetic powder, chemical plating CO a layer having excellent soft magnetic and hard-knock performance in perlite the surface degree COFE metal magnetic and microwave absorption performance.
    Added perlite metal glass beads of rubber with a high-frequency electromagnetic and microwave absorption properties of electroless copper plating on the surface, and can be used as a conductive filler, with glass beads after electroless copper plating after research showed that: in the polymer can be used for electromagnetic shielding.
    Perlite above proves once again that the new discovery, huge the perlite future development potential, but also to perlite technology research, there is still a long way to go. Man of iron, and CHAMC. Wishes the perlite technical development can go further, and make more contributions to the state and society.
