The fluorinated mica crystals have very good
high temperature resistance, corrosion resistance and light transmission
properties, and can work for a long time at a high temperature of 1100°C.
No reaction occurs
with strong acids and alkalis; complete light transmittance (pure and
transparent). The natural mica plates traditionally used in the observation
window of high-pressure boiler water level gauge are all brown, and the light
transmittance is not good, and the temperature resistance is in the range of
200-700°C, especially the corrosion resistance is poor. The boiler steam drum
water in thermal power plants contains alkali. After reacting with natural mica
and alkali, it is washed with hot air and hot water, and it is prone to
fluffing, scaling, and being broken. In the short term (about 1-2 months), the
water level is not clearly understood. After being broken, it can easily cause
leakage. The fluorite mica does not react with the acid-base solution, and does
not react with water in the hydration reaction, so that it does not form a
layer, does not scale, and does not break. In the long-term (2 to 3 years)
scouring of high-temperature and high-pressure water (including acid and
alkali), the original clarity and transparency can still be maintained. In
China, it has been widely applied to the observation window of steam boiler
water level gauge in high-pressure boilers of thermal power plants. It has also
been selected by Japanese BBK company and NDK (Colin) company for the
observation window of high pressure boiler drum level gauge.
