Gulf cryo offers high quality gases and on-site supply schemes for large consumers of gases. The
sensitivity of gas demand in the glass industry is clearly understood by Gulf Cryo, which
ensures reliable
supply solutions for gases.
Manufacturing gases dates back many centuries. The techniques and
processes
of glass making have evolved over time. In modern day society glass is an integral part of daily
life used
extensively in construction, automobile industry and domestic applications. In glass
manufacturing,
combination between chemical composition and physical properties varies with the application and
the
environment to which the glass will be exposed. Once considered an art, now glass production is
a
large-scale industry involving sophistication and technology that industrial development offers.
Present day
glass, can be categorized as tableware glass, float glass and optical glass fibres.
Sub-classification are
done based on the nature of the application and the customer’s demand.
The glass industry by virtue of the nature of the product is very critical when it comes to
application of
glass since abnormalities are easily identifiable in the final product. A variety of gases are
used in
different processes in glass making. Impurities in gases have to be checked and maintained
within the
allowable limits, which otherwise would result in large waste of volumes.
Optical and thermal properties are strength are some of the key characteristics driving the
glass industry.
Parts of these properties are attributable to the quality of gases used in the process. Changes
in the
purity
levels or the mixing ratios of gases are made to alter the quality of gases.
It is used primarily for two applications: for glass melting in the furnaces and for glass
polishing to give
a nice shiny appearance. It is either used mixed with air or oxy-fuel / Oxy-hydrogen
burners.
it finds a common use as a lubricant spread over the mold in glass bottle and tableware
manufacturing. When
exposed to direct heat it ensures that the glass in contact with it can be easily
removed.
use of nitrogen is primarily to create an inert atmosphere over a n bath and to maintain a
positive pressure
for float glass manufacturing.
Extensively used for glass coating on float glass to produce the coloured reflectasol (Solar
control glass)
to meet the twin requirement , functional & aesthetic, of architects.
It used mixed with Nitrogen in the float glass process to displace the oxidant from the bath. It
forms water
when reacted with oxygen and expelled from vets in the baths. The mixing ratio of hydrogen with
nitrogen
varies with the amount of oxygen in the bath. Other applications of hydrogen involve heat
treatment of fiber
optic pre-forms.
Several other gases such as helium, argon, neon and high
purity speciality gases are used by glass industry,
ranging from drawing of fiber optic pre-forms to gas filling in bulbs and tube lights for
imparting various
colors and lighting characteristics.
