High Resistance Acid Proof Refractory Brick
Acid proof brick a kind of corrosion resistant refractory material,
acid proof blocks are manufactured with quartz, feldspar and clay
as the main raw materials through oxygenolysis in the high
temperature. acid proof block has high acid-alkali resistance
property, low water absorption and are not easy polluted by medium,
acid proof bricks can be used in the anti corrosion engineering
such as petroleum, chemical engineering, metallurgy, electric
power, chemical fiber, papermaking, pharmacy, chemical fertilizer,
food, dairy industry and so on.
Acid Proof Brick Description
Acid resistant brick is a refractory brick with strong acid
resistance and acid resistant bricks can be widely used in the
industries. Acid resistant block is the ideal choose for your
project with their features of proof pressure, corrosion
resistance, easy to clean and acid base resistance. acid resistant
blocks have dense structure, which can resist any pH indicator
alkaline medium in the normal temperature, but not resist melting
alkali in high temperature. acid resistant firebrick with over 93%
SiO2 content, adopt silica as the main raw material and can resist
acid furnace slag erosion. acid proof fire brick is mainly used in
all kinds of furnaces and kilns with acid chemical component.
Properties of Acid Proof Brick
.High temperature resistance,
.High mechanical strength,
.Good resistance to wear,
.Good thermal shock resistance,
.Good resistance to furnace slag erosion,
.Strong resistance to acid erosion,
.Low water absorption and low apparent porosity.
Manufacturing Process of Acid Proof Brick
Main material of acid proof firebrick is quartz, feldspar and clay,
acid proof refractory block is a kind of anti corrosive material by
high temperature oxygenolysis. acid proof refractory brick has the
characteristics of high acid resistance, low water absorption, not
easy to be oxidized at normal temperature, not easy to be polluted
by medium. except the hydrofluoric acid and hot phosphoric acid,
acid proof fire block has excellent anticorrosive properties to wet
chlorine, saline water, hydrochloric acid, sulphuric acid, hydrogen
nitrate and other acid and the any concentration alkaline at normal
temperature.

Application of Acid Proof Brick
As the strong acid resistance property of acid proof brick, they
can be used in the high temperature equipments with acid atmosphere
and slag erosion, and also acid proof block can be widely applied
to the lining construction of tower, pool, tank, groove of the
petroleum, chemical industry, chemical fertilizer, pharmacy,
brewing, dairy product, papermaking, smelt, chemical fiber and
electroplating, chemical laboratory, electricity generation, gas
and other industry.
