In modern industrial production, the application of heat insulation materials is very important, especially in high temperature environment, good heat insulation performance can not only improve energy utilization efficiency, but also effectively reduce production costs and ensure the safe operation of equipment. Diatomite insulating brick, as an excellent thermal insulation material, has been widely used in many industrial fields because of its unique physical and chemical characteristics.

I. Product Overview

Diatomite insulating brick is a kind of insulating brick made of diatomite, which has the characteristics of low density, high thermal insulation, good thermal shock resistance and high temperature resistance. The classification temperature of this kind of brick is between 1610 and 1780 degrees Celsius, which can meet the needs of most industrial furnaces. Its main components include silicon dioxide (SiO₂), aluminum oxide (Al₂O₃) and iron oxide (Fe₂O₃), which give diatomite insulating brick excellent fire resistance and heat insulation performance.

II. Product characteristics

Diatomite insulating brick has the following remarkable characteristics:

Low thermal conductivity: Its thermal conductivity is only 0.11-0.23 W/m k at 300°C, which means that it can effectively prevent heat transfer, thus achieving good thermal insulation effect.

High strength and corrosion resistance: Diatomite insulating brick has a cold compressive strength of 0.8-5.0 MPa, can withstand certain mechanical pressure, and has good corrosion resistance, which is suitable for various harsh industrial environments.

Low heat capacity: Low heat capacity enables diatomite insulating brick to rapidly heat up in high temperature environment, reducing energy waste.

Low shrinkage: After firing at high temperature, its linear shrinkage is only 0.5%, which ensures the dimensional stability of the brick.

High fire resistance: able to withstand the service temperature up to 900°C, ensuring long-term stable operation in high temperature environment.

Good thermal shock resistance: Diatomite insulating brick can keep its structure intact and is not easy to crack or deform under the alternating environment of high temperature and low temperature.

Significant energy-saving effect: due to its excellent thermal insulation performance, it can effectively reduce heat loss, thus reducing energy consumption and achieving the goal of energy saving and consumption reduction.

III. Application fields

Diatomite insulating brick is widely used in the following fields:

Industrial furnace: As the thermal insulation lining of the furnace, it can effectively reduce the heat loss and improve the thermal efficiency of the furnace.

Metallurgical furnace: used as furnace lining and heat insulation layer in metallurgical process to protect the furnace structure and prolong the service life of the furnace.

Electric furnace: In the electric furnace, diatomite insulating brick can withstand high temperature and maintain good heat insulation performance, ensuring the stable operation of the electric furnace.

Fire-proof material: used as the insulation layer of fire-proof facilities such as fire doors and firewalls to improve fire-proof performance.

Thermal equipment: such as heat insulation materials for drying furnaces, heating furnaces and other equipment to reduce the energy consumption of equipment.
