1.IntroductionFoam glass cellular glass pipe is a new inorganic insulation material with glass as the main raw material,Website:http://www.lfinsulation.com, made through adding appropriate blowing agent, heating and roasting by high temperature tunnel kiln, and at last annealing and cooling process, which has a uniform independent airtight air-gap structure. It completely retains the chemical stability of inorganic glass, with properties of low volume density, low heat conductivity, anti-moisture permeability, water repellence, non-combustibility, no virulence variation, rodent proof, high mechanical strength, easy processing, capability of resistant all chemical erosion except hydrogen fluoride.Foam glass cellular glass not only has excellent thermal insulation performance of non-toxic, chemical stability, and no deterioration at a wide temperature range from ultra-low to high temperature, but also has the effect of moisture proof, fire proof, and corrosion resistance.When it is used in the environment of low temperature, copious cooling, underground, outdoor, inflammable, damp and chemical corrosion, it is safe, reliable and durable, known as "never replaced permanent heat insulation material"2.
