Currently, it makes microwave radar, infrared, radar or other electromagnetic wave radar and acoustic detection system shield absorbing materials have been widespread concern in the military field.
Near infrared reflective material can be used in aviation, aerospace, building materials, vehicles, weapons and other fields. Cenospheres powder density is small, the metal surface after its treatment, can be substituted for the denser metal electromagnetic wave absorbing powder (RAM) or prepared electromagnetic shielding (EMI) material.
In recent years, researches on the chemical coating of glass and ceramic hollow beads
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 the civilian technology only strengthen the performance of thermal insulation
coatings.Other studies have loved incense activation method using silver nitrate
cenospheres coated Ni-Co-P, can be used for electromagnetic shielding and microwave
absorbing, the civilian aspects of the material can be made anti-electromagnetic
radiation, military aspects can be made invisible absorbing material.Co-density metal
powder layer preparation Ling Guoping such as the use of chemical plating method,
hollow glass beads coated with magnetic table, Co plating layer having excellent soft
and hard magnetic properties. Sung-Soo Kim studied in the hollow ceramic beads plated
metal layer of Co Fe magnetic and microwave absorption properties.Studies show that adding metallized hollow ceramic beads of rubber to high-frequency
electromagnetic and microwave absorption properties have. S.Shukla in fly ash particles
and other surface copper plating, copper plating after the fly ash particles can be used
as the conductive filler, for use in the polymer can be applied to an electromagnetic
shield.
