Fiber reinforcement foam glass

Abstract

The invention relates to foam glass, in particular to fiber reinforcement foam glass. The fiber reinforcement foam glass comprises foam glass and is characterized in that reinforced fiber is arrangedin the foam glass; the reinforced fiber relates to any one or the combination of more than any two of glass fiber, carbon fiber and metal fiber. The diameter of the reinforced fiber is 4.0-25mum; andthe length of the reinforced fiber is 0.20-10.0cm. The invention has the advantages that the foam glass can effectively reinforce the strength of the foam glass, reduces the abrasion thereof in the processing, transformation and use process; and the fiber and the foam glass body can be firmly and effectively banded together and are not easily cracked in the annealing process.

Description

technical field [0001] The invention relates to a foam glass, in particular to a fiber-reinforced foam glass. Background technique [0002] Foam glass uses cullet as the main raw material, adding foaming agent, modifier, foaming accelerator, etc. to the finely ground glass powder, and placing it in a specific mold frame after uniform mixing. Heat it to 700-900°C in a tunnel firing kiln or other foaming furnaces to soften and expand to form a porous glass material filled with countless uniform bubbles. Then take it out from the mold frame, send it into the annealing furnace to cool slowly to room temperature, and finally cut it into a certain size by sawing. [0003] Foam glass has the advantages of low density, low thermal conductivity, fire prevention, corrosion resistance, wide temperature range, airtight, non-moisture absorption, easy processing, and no rodent bites. Foam glass has a wide range of uses, not only as heat insulation materials for petrochemical industry, f...
