Electromagnetic shielding and microwave absorption applications

2015-01-12 04:24:52 1890
Currently, the use of microwave radar, infrared, radar or other electromagnetic radar and acoustic detection system shield absorbing material has been widespread concern in the military field. Near-infrared reflective material can be used in aviation, aerospace, construction materials, vehicles, weapons and other fields. Hollow glass bubble powder density is small, the metal surface after its treatment, can be substituted denser metal powder or electromagnetic wave absorption preparation screen material used.
In recent years, researches on the chemical coating of glass and pottery porcelain coated hollow glass bubble findings could change their optical and electrical properties and thermodynamic properties. In particular, can improve absorption and near-infrared reflectance of the electromagnetic wave after nickel, cobalt coating has been applied to military security, as a civilian technical performance just reinforced insulation coatings. Branch and other studies have loved incense activation method using silver nitrate coated hollow glass bubble in Ni-Co-P, can be used for electromagnetic shielding and absorbing microwave civilian aspects can be made anti-electromagnetic radiation material, military aspects can be made invisible absorbing material. Co metal layer, such as the preparation of low-density magnetic powder Ling Guoping chemical plating method, hollow glass bubble surface coated with a magnetic, chemical plating Co layer with excellent soft and hard magnetic properties.
Sung-Soo Kim studied in hollow ceramic beads plated Co, Fe metal layer on the magnetic and microwave absorption properties. Studies show that the addition of metal rubber hollow ceramic beads for high frequency electromagnetic and microwave absorption properties have. S.Shukla such as fly ash hollow glass bubble surface copper plating, copper plating through hollow glassbubble fly ash can be used as a conductive filler in the polymer can be applied with an electromagnetic shield.
