• 化学的特性

  Fibrous glass is the name for a manufactured fiber in which the fiber-forming substance is glass. Glasses are a class of materials made from silicon dioxide with oxi des of various metals and other elements, which solidify from the molten state without crystallization. Typically, glass filaments >3 μm in diameter or glass “wool” with diameters down to 0.05 μm & length >1 μm.A fiber is considered to be a particle with a length-to-diameter ratio of 3:1 or greater. The volume of small diameter fiber pro duction has not been determined. Fibers with diameters less than 1 μm are estimated to comprise less than 1% of the fibrous glass market. Specific gravity (H2O:1) = 2.5. Hazard identification (based on NFPA-704 M Rating System): Health 1, flammability 0, reactivity 0. Insoluble in water.

  The major uses of fibrous glass are in thermal, electrical, and acoustical insulation; weatherproof ing, plastic reinforcement; filtration media; and in structural and textile materials.

• 廃棄物の処理

  Fibrous glass waste and scrap should be collected and disposed of in a manner which will minimize its dispersal into the atmosphere. Emphasis should be placed on covering waste containers; proper stor age of materials; and collection of fibrous glass dust. Clean-up of fibrous glass dust should be performed using vacuum cleaners or wet cleaning methods. Dry sweeping should not be performed.
