Aerogel refractory board is a new type of fireproof refractory building material, silicate board as a traditional fireproof refractory material, both have excellent fireproof refractory performance. Naturally, some people want to know which aerogel refractory plate and silicate plate is better, I will analyze the production and advantages and disadvantages of aerogel refractory plate and silicate plate to explore which of the two is better.

First, aerogel refractory board
Aerogel refractory board is composed of aerogel and glass fiber cloth. Aerogel is a low density solid material with excellent thermal insulation and lightweight properties. The aerogel refractory board formed by combining the aerogel with the glass fiber cloth has good fire resistance and heat insulation properties.

Advantages of aerogel refractory board:

1, excellent thermal insulation performance: aerogel itself is a low-density porous material, with a very low thermal conductivity (0.015~0.025W/(m·K)), can effectively isolate heat transfer, so it has excellent thermal insulation performance.
2, lightweight: Due to the low density characteristics of aerogel, aerogel refractory board is relatively light, easy to handle and install.
3, fire resistance: aerogel itself has good high temperature resistance, so the aerogel refractory board can maintain stable performance at high temperature, with good fire resistance.
4, good chemical stability: aerogel refractory plate has good stability in conventional chemical environment, not easy to be corroded by chemical substances.
5, environmental protection: aerogel refractory material itself is non-toxic and harmless, in line with environmental requirements.
Disadvantages of aerogel refractory board:
1, high cost: The production process of aerogel refractory board is complex, and the cost of raw materials is high, so the price of aerogel refractory board is higher than that of traditional building materials.
2, low compressive strength: due to the low density characteristics of aerogel, its compressive strength is relatively low, not suitable for use as a load-bearing structural material.

Second, silicate plate
Silicate plates are composed of Portland cement and fiber reinforced materials. Portland cement is a special kind of cement, made of limestone, silica and other raw materials after high temperature calcination. Silicate plate because of its excellent fire resistance, chemical resistance and tensile strength.

Advantages of silicate plate:

1, fire resistance: silicate plate has excellent fire resistance, can effectively resist high temperature, has good fire resistance.
2, chemical corrosion resistance: silicate plate in the environment of common chemical substances has good stability, not easy to chemical corrosion.
3, high strength: silicate plate has high tensile and compressive strength, which can meet certain load-bearing needs, and is suitable for some load-bearing walls and floors in building structures.
4, good thermal insulation performance: silicate plate has good thermal insulation performance, thermal conductivity of 0.038~0.044W/(m·K), can reduce energy consumption, improve the energy efficiency of the building performance.
5, stable physical properties: silicate plate in wet, dry and other environments can maintain more stable physical properties, not easy to deformation or damage due to environmental changes.
Disadvantages of silicate plate:
1, the heavier weight: silicate plate is relatively dense, so the weight is larger, which increases the difficulty of transportation and installation to a certain extent.
2, brittleness: silicate plate is relatively brittle, fragile. Careful handling is required during construction and installation to avoid damage.
3, poor processing performance: due to the high hardness of silicate plate, difficult to process and cut, not easy to bond, so the silicate plate processing cost is high.

In summary, if you need to focus on thermal insulation performance and fire performance, and do not need to consider load-bearing, the project budget is sufficient, aerogel board may be more suitable. If you only need fire performance, you need to bear weight, silicate plate is more suitable.
