In recent years, external wall ceramic insulation board with its excellent performance and unique advantages, gradually emerging, for building insulation has brought a new solution, open a new chapter in building insulation.

First, the composition and production process of external wall ceramic insulation board
External wall ceramic insulation board is not a single material of the plate, but a combination of a variety of materials, through the exquisite structural design and advanced technology to create. The outer layer is usually a ceramic sheet, which takes natural clay as the main raw material and adds a small amount of quartz, pumice stone, feldspar and other ingredients such as color. In the production process, the clay paste is extruded by a mold and then fired at a high temperature. High temperature firing this link is crucial, after about 1200℃ high temperature roasting, ceramic sheet not only obtained a stable physical and chemical properties, but also showed a rich variety of colors and textures, such as common red, yellow, gray and other natural colors, the color is glossy and warm, with natural affinity, excellent durability. This ceramic sheet finish layer not only gives the building exterior wall beautiful decorative effect, its dense structure also has good waterproof, anti-fouling and self-cleaning ability, can resist wind and rain, sun and rain and erosion of various pollutants, and keep the building appearance clean and beautiful for a long time.
The middle layer of the thermal insulation board is the thermal insulation core material, which is the core part to achieve the thermal insulation function. Common thermal insulating core materials include polystyrene foam, rock wool, polyurethane, foamed ceramics, etc. Different core materials have their own unique performance characteristics. For example, polystyrene foam has the characteristics of light weight and good insulation performance; Rock wool is known for its excellent fire performance and has certain thermal insulation capacity. Polyurethane has excellent thermal insulation performance, low thermal conductivity and good cohesiveness. Foamed ceramic insulation board is based on ceramic tailings, ceramic fragments, river silt and other as the main raw materials, using advanced production technology and foaming technology by high temperature roasting, it has low heat conductivity, non-combustible, fire prevention, aging resistance, good compatibility, low water absorption, weather resistance and a series of outstanding advantages. These thermal insulation core materials are carefully sandwiched between two layers of ceramic sheets, and through a special bonding process, each layer of materials is tightly combined as a whole to ensure the durability and stability of the thermal insulation effect.

Second, comprehensive analysis of excellent performance
Efficient thermal insulation, reduce energy consumption: One of the most significant properties of external wall ceramic insulation board is its excellent thermal insulation ability. Taking foamed ceramic insulation board as the core material, for example, its thermal conductivity is usually between 0.06-0.10W /(m · K), which is equivalent to traditional thermal insulation mortar, and even in some high-quality products, the thermal conductivity can be as low as 0.06W/(m · K). Such a low thermal conductivity means that heat is difficult to transfer through the plate, in winter, it can effectively prevent the outdoor cold air into the room, reduce the loss of indoor heat, so that the indoor temperature can be maintained stable, reduce the energy consumption of heating equipment; In the summer, it can block the solar radiant heat into the room, reduce the load of indoor air conditioning and refrigeration system, and reduce the consumption of electric energy. Relevant research data show that the use of external wall ceramic insulation board building, compared with the use of no insulation measures in the building, the annual energy consumption in heating and cooling can be reduced by 30%-50%, which is of great significance for easing the energy shortage and achieving energy conservation and emission reduction goals.
Class A fire performance for safety: In the field of building safety, fire performance is a crucial consideration. The ceramic sheet itself in the external wall ceramic insulation board is A non-combustible material, and some thermal insulation core materials such as rock wool and foamed ceramics also have excellent fire performance and can meet the A-level fire protection standard. In the case of foamed ceramic insulation board, it is calcined at a high temperature above 1200 ° C, and the combustion performance is A1, which has the fireproof performance of similar power plant refractory bricks. In the event of a fire, it will not burn, nor will it produce toxic and harmful gases, which can effectively prevent the spread of the fire, gain valuable time for personnel evacuation and fire rescue, and greatly improve the fire safety factor of the building. According to the statistics of the fire department, the damage degree of the buildings with grade A fire insulation materials in the fire is significantly lower than that of the buildings with non-grade A fire protection materials, and the casualties and property losses are correspondingly reduced.

External wall ceramic insulation board with its special material composition and structural design, showing superior weather resistance. After special treatment, the surface of the ceramic sheet has good anti-ultraviolet performance, and will not fade and age due to long-term sunlight exposure; The bond between the thermal insulation core material and the ceramic sheet is firm, and there will be no cracking, deformation, falling off and other phenomena in the process of thermal expansion and cold contraction caused by temperature change. Even in extremely harsh climatic conditions, such as hot desert areas, cold and windy polar regions and frequent rainstorm coastal areas, the external wall ceramic insulation board can maintain stable performance, and its service life can be the same as the life of the building, without frequent replacement, greatly reducing the later maintenance costs of the building.
Good waterproof and moisture resistance: the waterproof performance of the external wall ceramic insulation board is excellent. The compact structure of the ceramic sheet itself has a waterproof function, which can effectively block the penetration of rain. At the same time, in the selection of temperature retaining core materials, some materials with low water absorption characteristics are widely used, such as the water absorption of foamed ceramic insulation board is very low, usually ≤8%. This makes the plate in long-term contact with rain or wet environment, will not cause a large amount of moisture absorption and lead to reduced thermal insulation performance or sheet deformation. Good waterproof and moisture-proof performance not only ensures the durability of the thermal insulation effect of the thermal insulation board, but also avoids problems such as mold and rot on the wall caused by water intrusion, and prolongs the service life of the building.
