Fiberglass Factory

How does a fiberglass factory produce fiberglass?
Fiberglass is a form of glass made when glass is drawn into extremely fine fibers . These fibers
retain the tensile strength of glass and still remain very flexible. The most commonly used raw
material for fiberglass is quartz which is a form of silica which is the main component of sand.
Quartz is resistant to a vast majority of chemicals and can be extracted easily in the molten stage
. Molten glass from which fiberglass is made is forced through a platinum plate with small
openings. The fine fibers that emerge are combined without being twisted and spread on an apt
spindle. Mats of fiberglass are made from short fibers that diverge in a variety of directions.
These fibers are combined together with a thermosetting resin and a strong type of glue.

How does a fiberglass factory ensure the quality of fiberglass produced?
Fiberglass materials are sampled a number of times in the production process to maintain quality.
They are tested at different stages of production. They are tested before mixing to be fed to the
electric melter. The molten glass, glass fibers and final cured product at the end of the
production are tested to check the quality of the product. The bulk glass and fiber samples are
analyzed for chemical composition and the presence of mistakes are studied using chemical
analyzers and microscopes. Size distribution of the batch material is obtained by passing the
material through a number of different sized sieves. The final product is measured for thickness
after packaging according to specifications and the difference in thickness indicates the
deterioration in quality. A wide range of standardized test procedures are applied to optimize
product features like fiber diameter, bulk density, thickness etc.
