    Foam glass insulation material classification and application technology, foam glass, is a kind of fine glass powder as the main raw material, through the addition of foaming agent, after sintering foaming and annealing cooling processing, the uniformity is uniform. A new type of inorganic insulation material with a closed air gap structure.  
  There are many types of foam glass, which are classified according to different criteria as follows:  
  Separate heat foam glass and sound absorbing foam glass according to use  
 According to the raw materials used, ordinary foam glass, quartz foam glass, lava foam glass

  Divided into white, brown, yellow, pure black, etc. by color  
  According to the shape of the flat plate (code P) shell (code G)  
  According to the density, ≤150kg/m (code 150) 151~180kg/m (code 180)  
  The technical points of application of foam glass are as follows:  
  1. The matrix of the foam glass is glass, so it does not absorb water. The internal bubbles are also closed, so there is no capillary phenomenon and no penetration. Since these two points make the foam glass superior to any other inorganic and organic insulating materials in most physical and chemical properties, foam glass is currently the most ideal cold insulation material.。
  2、The mechanical strength is high and the intensity change is proportional to the apparent density. It has excellent pressure resistance and can withstand the erosion and load of the external environment more than other materials. The combination of excellent compression resistance and moisture barrier properties makes foam glass the most ideal thermal insulation material for underground pipelines and tank foundations.。
  3、Foam glass has good thermal and moisture permeability, so the thermal conductivity is stable for a long time, does not change due to environmental influence, and has good thermal insulation performance.。
  4、Foam glass is a matrix wet glass, so it does not ignite or burn, and is an excellent fireproof material. Foam glass has a working temperature range of -200~430°C, a small expansion coefficient (8×10°C) and is reversible, so the material properties are unchanged for a long time, it is not easy to be brittle, and the stability is good.。
  5、Foam glass has good sound insulation performance and strong absorption of sound waves. The average penetration loss is 28.3dB in 60~400Hz.。
  6、Foam glass has good dyeing performance and can be used as insulation material。
  In summary, it can be seen that foam glass can be used as a preferred building insulation material\fireproof decorative material.。
