Inorganic heat insulation board series products are a new type of fire-resistant and heat-insulating material made of pure inorganic materials and processed through large-scale automatic continuous production lines. The service temperature ranges from 900°C to 1300°C, and it can be used as the backing of various industrial kilns, which solves the problem of thermal insulation of the kiln well. The bulk density of the Rongsheng Inorganic Thermal Insulating Board can be processed and produced within the range of 0.35~0.6 g/cm3. Under the condition of 350°C, the thermal conductivity of the Rongsheng inorganic insulation board is controlled within the range of 0.11~0.13W/(m·K), and the strength can be controlled within the range of 1-2 MPa. The maximum size can be processed into 1m*2m.
Main Features of Inorganic Thermal Insulating Board
Low thermal conductivity, more energy-saving. The composition structure of Rongsheng inorganic heat insulation board is composed of nano micropores, so the product has good heat insulation performance.
No shrinkage and small gaps after heating. Within the specified operating temperature, the heating permanent line change rate of the Rongsheng Inorganic Thermal Insulating Board is less than 0.5%, and it will not shrink after long-term use. For ordinary thermal insulation boards, the heating permanent line change rate reaches 2%-3% shrinkage. The shrinkage is more than 4 times that of Rongsheng’s new Inorganic Thermal Insulating Board.
Completely free of fiber and organic matter, it can be used for a long time under various working conditions. No chalking, no attenuation.
High strength and wide application range. Rongsheng’s Inorganic Thermal Insulating Board has better compressive strength at room temperature. Compared with ordinary thermal insulation boards, its normal temperature compressive strength can reach more than 3 times, and it also has good strength after burning. Long-term use at high temperatures is more secure and has a wider range of use.
Rongsheng’s Inorganic Thermal Insulating Board has no stimulation to the human body and no pollution to the environment. The construction is convenient, healthy, and environmentally friendly.
Rongsheng Inorganic Thermal Insulating Board has good quality control and a large production capacity. It is not restricted by environmental protection, and the delivery time is guaranteed.
