The advantages of low porosity clay brick in different industries are as follows:

I. Metallurgical industry

High corrosion resistance: the porosity of low porosity clay brick is low, usually lower than 17%, even as low as 13%-15%, which makes the brick more compact and can effectively resist the corrosion of molten iron and slag.

High strength and high fire resistance: its compressive strength is high, the compressive strength at room temperature can reach more than 68 MPa, and the softening temperature under load can reach about 1500°C, which can maintain stability in high temperature environment.

Prolonged service life: Because of its excellent corrosion resistance and stability, the service life is 2 to 3 times longer than that of ordinary clay bricks, and the replacement frequency of refractory materials is reduced.

The energy-saving effect is remarkable: the low thermal conductivity of low porosity clay brick can effectively reduce heat loss, improve energy utilization efficiency and reduce energy consumption.

II. Glass industry

Excellent corrosion resistance: low porosity clay brick has strong tolerance to acidic and alkaline substances and glass liquid, and can resist the corrosion of corrosive gases and substances inside the glass kiln.

Good thermal shock stability: it can resist the thermal stress impact caused by rapid temperature change, prevent the cracking and peeling of refractory bricks, and is suitable for parts with frequent temperature changes such as regenerator of glass kiln.

Improve production efficiency: its use can reduce the maintenance times and downtime of the kiln, thus improving the efficiency of glass production.

Reduce the production cost: Although the initial investment is high, it can reduce the production cost in the long run because of its long service life and low maintenance cost.

III. Chemical industry

Strong chemical corrosion resistance: the low porosity and high density structure of low porosity clay brick can effectively resist the corrosion of acidic or neutral chemicals, and is suitable for chemical reactors and heat exchange equipment.

High-temperature stability: it can maintain stability in high-temperature environment, and it is not easy to be ablated and deformed to ensure the normal operation of the equipment.

Reduce environmental pollution: its compact structure can effectively block the infiltration and leakage of harmful gases and reduce environmental pollution.

IV. Thermoelectric industry

High temperature corrosion resistance: in the lining of coal-fired boilers and gas-fired boilers, clay bricks with low porosity can resist the corrosion of high temperature flue gas and fly ash.

Energy saving and environmental protection: The low thermal conductivity of low porosity clay brick can effectively reduce heat loss, improve energy efficiency and reduce carbon emissions.

V. Cement industry

High temperature resistance and corrosion resistance: it is suitable for preheater of cement kiln, and can withstand high temperature airflow, chemical erosion and wear.

Improve the stability of equipment: its high density and low porosity make it possible to maintain structural stability in high temperature environment and reduce the maintenance cost of equipment.

To sum up, clay bricks with low porosity have obvious advantages in metallurgy, glass, chemical industry, thermoelectric and cement industries, which can effectively improve production efficiency, reduce production costs and reduce environmental pollution by virtue of their excellent corrosion resistance, high strength, high fire resistance, good thermal shock stability and low thermal conductivity.
