Description
, Factory production of quartz endoscopy performed JC******1
standard, as follows: two main performance, quartz glass Jane
solution: quartz glass molten silica (Si*2) from a single component
of the vitreous material. Because it has a unique series of
excellent performance, and "glass king" reputation, as an important
industrial material, is widely used in semiconductor electronics,
electric light, metallurgy, chemical industry, light industry,
building materials, optics, nuclear , space technology, defense
equipment, industrial and modern science and technology fields.
Third, the various properties of the quartz glass: 1. Mechanical
properties: the mechanical properties of the quartz glass is better
than glass and ceramics, some of the major indicators of density
2.2g/cm3 Modulus of elasticity **0 * **3kg/cm3, tensile
strength***0kg / cm3, the dissolved hardness of 5.**6.5, at ***0 °
C annealing temperature strength reaches a maximum, which is one of
the major characteristics of the quartz glass. 2. Thermal
properties: 5.4 * ***7, due to the very small coefficient of
thermal expansion of the quartz glass, quartz glass, equivalent to
ordinary glass 1/***1/*0, minimal coefficient of thermal expansion
in the number of the average expansion of the *****0 ℃ , so it
withstands the ability to withstand temperature difference between
the hot and cold CML, ******5 ℃ generally can withstand thermal
shock test. 3. Chemical properties: quartz glass is excellent in
acid-resistant material, in addition to hydrofluoric acid and **0 °
C or higher phosphoric acid solution until it reaches the boiling
point of any concentration of the erosion of the quartz glass are
very small, also be resistant to the erosion of the neutral
substance, it is the same alkali although should be, but the
reaction rate is relatively small, therefore, quartz glass is a
good resistance to chemical erosion material. 4 Optical properties:
quartz glass is transparent to ultraviolet, visible, near-infrared
best performance of the glass, quartz glass, there are many unique
properties
