Fiber Glass Wool Usage And Synthesis
- Chemical Propertiesgenerally sold as a wool-like material
- Chemical PropertiesFibrous 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.
- UsesThermal, acoustic, and electrical insulation (coarse fibers in bats or sheets); decorative and utility fabrics such as drapes, curtains, table linen, carpet backing, tenting, etc.; tire cord as belt between tread and carcass; filter medium; reinforced plastics; light transmission for communication signals; reinforcement of cement products for construction use.
- UsesGlasswool is used for thermal and acoustical insulation in construction and ship building; for air filtration in furnaces and airconditioning systems.
- DefinitionGeneric name for a manufactured fiber in which the fiber-forming substance is glass (Federal Trade Commission). Noncombustible.
- Definitionglass: Any noncrystalline solid; i.e. asolid in which the atoms are randomand have no long-range ordered pattern.Glasses are often regarded as supercooledliquids. Characteristicallythey have no definite melting point,but soften over a range of temperatures.
The common glass used in windows,bottles, etc., is soda glass,which is made by heating a mixtureof lime (calcium oxide), soda (sodiumcarbonate), and sand (silicon(IV)oxide). It is a form of calcium silicate.Borosilicate glasses (e.g. Pyrex) aremade by incorporating some boronoxide, so that silicon atoms are replacedby boron atoms. They aretougher than soda glass and more resistantto temperature changes,hence their use in cooking utensilsand laboratory apparatus. Glasses forspecial purposes (e.g. optical glass)have other elements added (e.g. barium,lead). See also spin glass.
- HazardA possible carcinogen.
- Health HazardGlass fibers cause skin, eye, and upper respiratory tract irritation; although earlier classified by IARC to be a Group 2B carcinogen, possibly carcinogenic to humans, more recent evaluations indicate the human risk, if any, to be minimal.
- Industrial usesFine flexible glass fibers made from glass are used for heat and sound insulation, fireproof textiles,acid-resistant fabrics, retainer mats for storage batteries, panel board, filters, and electrical insulating tape, cloth, and rope. Molten glass strings out easily into threadlike strands, and this spun glass was early used for ornamentalpurposes but the first long fibers of fairly uniformdiameter were made in England by spinningordinary molten glass on revolving drums.
The standard glass fiber used in glass-reinforced plastics is a borosilicate type known asE-glass.Glass cloth of plain weave of either continuous fiber or staple fiber is much used forlaminated plastics.
- Industrial usesGlass, one of the oldest and most extensivelyused materials, is made from the most abundantof Earth’s natural resources — silica sand. Forcenturies considered as a decorative, fragilematerial suitable for only glazing and artobjects, today glass is produced in thousandsof compositions and grades for a wide range ofconsumer and industrial applications.
- Industrial usesThe primary engineering benefits of glass fibersare their inorganic nature, which makesthem highly inert; high strength-to-weightratio; nonflammability; and resistance toheat, fungi, and rotting.
Glass fibers are produced in both filamentand staple form. Their major engineering usesare thermal and/or acoustical insulation andas reinforcements, primarily for plastics.
- Potential ExposureThe major uses of fibrous glass are in thermal, electrical, and acoustical insulation; weatherproof ing, plastic reinforcement; filtration media; and in structural and textile materials.
- Waste DisposalFibrous 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.
