Production Technique
The advanced CWCN equipment and
double side needling blanket production line are used
in the production of thess products. Both the equipment
and technique are of leading level. Different raw materials
(for example, flint clay,SiO2¡¢Al2O3,Zircon sand, etc.)are
used in the production of aluminum silicate fiber needled
blankets, and the fiber formed is made into the product
through sedimentation, thermal setting, lengthwise and
crosswise cutting and rolling. The product is homogenous
with smooth and even surface and high tensile strength
. As the aluminum silicate needled blanket does not
contain any cementing agent,its resistance to heat is
reatly enhanced.
Application
Thermal insulation in electric
power boiler, steam turbine and nuclear power station.
Wall lining of chemical industrial high temperature
reactor and heating equipment.
Wall lining of high temperature piping, irregular piping
and industrial furnace. Thermalinsulation for eliminating
stress in welding.
