Argillaceous brick norms, price and composition

Argillaceous brick composition:

The main and chemical composition of argillaceous brick is silicon of alumina, 2 oxidation, 3 oxidation natrium of Potassium of calcium of 2 iron, oxidation, oxidation, oxidation, titanium dioxide

Argillaceous brick

It is with clay clinker is aggregate,

Fireproof

Argillaceous brick

chemical composition: Al2O3 content 30%-48% , siO2 content is reached for 50%-65% a few

Alkali metal

,

Alkaline-earth metal

Oxide TiO2, Fe2O3.

Mineral composition divides commonly for:

Mo Laishi

, photograph of Fang Shiying and quartz, glass.

Make the fireproof material that is 30%-48% into Al2O3 content for bond. It is a kind of utility the refractory products with extensive, the biggest crop.

Element of argillaceous brick price:

Because argillaceous brick uses a field very wide, the price is lower also, serving as firebrick to say price factor is very big impact, make red brick pit for instance, power plant chimney, flue do not exceed 1000 degrees of the following microtherm furnace to be able to satisfy much to use a requirement, the price of all clay brick very those who get domestic and international user love.

1,

Fireproof degree

It is 1580-1750 ℃ commonly, increase along with Al2O3/SiO2 and rise, when low frit content matter content relatively a long time, of goods

Fireproof degree

Reduce significantly.

2,

Loading bate temperature

It is 1250-1450 ℃ about, its span is wider. Begin metabolic temperature inferior, with 40%

Be out of shape temperature

Differ make an appointment with 200-250 ℃ .

3,

Linear expansion coefficient

Inferior, 20-1000 is average

Linear expansion coefficient

For 4.5-6x10-6/ ℃ . Its

Thermal conductance

4, heatproof shake sex is good, fluctuant range is bigger. 1100 ℃ water-cooling is more than 10 times commonly circularly. This as inferior as the linear expansion coefficient that pastes earthy product, brilliant change effect not remarkable and the plasticity below high temperature is concerned.

5, fight chemical aggressivity: Because its belong to weak acidity, have stronger fight acid slag to erode ability, the counteractive ability that erodes to basic material is weaker.

6, argillaceous brick belongs to acidity refractory products. Along with SiO2 content increases and acidity increases. It is had to acidity slag fight certainly erode ability, face alkalescent and slaggy erodent counteractive ability is poorer, because this clay brick is appropriate,use as the liner of acidity kiln furnace. Also use at biscuit of kiln of blast furnace, hot-blast stove, glass, charcoal to burn furnace to wait for furnace of high temperature kiln.

Also inferior.

The dimension of straight form brick, include the length A that by its geometrical appearance place sets, width B reachs ply C.

Note: 1, the straight form brick that matchs build by laying bricks or stones to brick of as thick as brick of perpendicular thick wedge or side wedge, a of dimension matching build by laying bricks or stones is equal to its ply C, brick of straight to matching build by laying bricks or stones with brick of perpendicular wide wedge form,

, long to not be more than 345mm brick, the brick seams ply δ to take 1mm, long to not be less than 380mm brick, the brick seams ply δ to take 2mm.
