Mullite refractory insulating refractory bricks jm23 jm26
JM23 insulation brick are processed through moulding under high
pressure ans sintering at high temperature , and JM23 insulation
bricks with feature of strong strength,steady bulk at high
temperature and small creep rate, which are available for hot blast
stove of large and middle size.
JM23 Insulation Brick Description
JM23 insulating brick uses high pure mullite as raw material, JM23
insulating bricks are made by adding alumina powder according to
different type and then sintering in high temperature. JM23
insulation firebrick is the new energy saving material for
insulation. JM23 insulation fire brick is produced accordance with
German industrial standard that especially for export to foreign
countries.
Properties of JM23 Insulation Brick
.Excellent compression strength,
.Excellent heat stability,
.Low thermal conductivity,
.Low heat storage,
.High alumina, low iron and alkali flux content.
