Reinforcing agent of
refractory material and ceramics
Usually, sodium lignosulphonate can make ceramic atom hard felted
to build up the intensity of ceramics in the manufacturing process
of wall brick and firebrick when the temperature is under **0
degree centigrade, and
also can disappear automatically if the temperature is between **0
and **0 degree centigrade. When its volume is 0.2%*0.8% of the dry
adobe material, the intensity of ceramics adobe can increase more
than *0%**0%. But in the manufacturing process, the speed of
temperature elevation can\'t be too fast in order to avoid
spumescence of surface.
