Chemische Eigenschaften
generally sold as a wool-like material
Verwenden
Thermal, 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.
Definition
Generic name for a manufactured fiber in which the fiber-forming substance is glass (Federal Trade
Commission). Noncombustible.
Allgemeine Beschreibung
Silica is a naturally occurring material in minerals, flint and in some plants in crystalline phase. Silica used in industries is in synthetic form. Surface area, pore volume, pore size and particle size are independently controllable to some extent. The crystalline silica may be classified based on atmospheric pressure as:
a. Quartz = 1143K
b. Tridymite 1143 - 1743K
c. Cristobalite = 1743, over 1973K it forms amorphous vitreous silica glass.
Hazard
A possible carcinogen.
Health Hazard
Glass 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.
Industrielle Verwendung
Fine 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.
Source
Kaolin and Ground silica are the major batch components in the production of fiberglass
mögliche Exposition
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.
Waste disposal
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.
