CERAMIC FIBER BLANKET
Description:
Ceramic fiber blankets are made through process of pricking, heat-shaping, cutting and rolling. They feature high quality of tensile strength, texture uniformity and plane surface, high temperature, chemical corrosion resistance, thermal shock stability and low thermal conductivity. They have low density, good resiliency and excellent sound absorbing and filtering property.
Application:
Mainly serve as the ceramic fiber lining for industrial furnaces, heating equipment and high- temperature pipelines, such as
Metallurgy Industry: heating furnaces, heat treatment furnaces and ladle insulated cover
Mechanism industry: thermal insulation material for electric power boilers, gas turbine engine and nuclear power plant
Petrochemical industry: the lining of high-temperature reaction equipment and heating equipment in chemical fields, like converting furnaces, constant/reduced pressure furnaces, cracking furnaces, flue lining.
Ceramics and electro ceramics: roller hearth furnaces, tunnel furnaces , shuttle furnaces and other kinds of furnaces
