In
the huge glass family, there is a type of glass that is crystal clear,
high-grade and elegant, known as the "glass noble", it is Low iron
glass.
Ultra
white glass is a kind of ultra-transparent low-iron glass, also known as
low-iron glass and high-transparency glass. With excellent physical, mechanical
and optical properties, it can be processed and manufactured in various ways
like other high-quality float glass. Low iron glass has the following characteristics:
1. Crystal texture, beautiful appearance: Low
iron glass has very good permeability, has crystal texture, and has a super
high appearance value, which can better meet the needs of designers and
perfectly integrate with architectural design.
2. Low self-explosion rate: Generally
speaking, low iron glass raw material contains less impurities such as NiS, and
it is controlled more precisely during the melting process of the raw material.
Compared with clear float glass, it has a more uniform composition, thus
greatly reducing the temperature after tempering. Likelihood of
self-destruction.
3. Color consistency: The iron content in
the raw material of ultra-white glass is only one-tenth or even lower than that
of ordinary glass, and it absorbs less in the green wavelength band of visible
light, thus ensuring the consistency of glass color.
4. High visible light transmittance and good
permeability: the light transmittance of float glass is about 80%, and the low
iron glass with a thickness of 6mm has a visible light transmittance of 91%,
which is as crystal clear as crystal. In addition, high light transmittance
also effectively reduces light refraction and reflection, which not only
reduces light pollution, but also prevents chromatic aberration and deformation
of objects between the inside and outside of the glass, enhancing authenticity.
5. High technical content and strong
profitability: The technical content of low iron glass is relatively high,
the production control is difficult, and it has strong profitability. The high
quality also determines its high price. At present, the price of low iron glass
is 1~2 times that of float glass, and the technical barriers are relatively
high.
