ceramic fiber insulation blanket vs. aluminum silicate fiber blanket
The main difference between ceramic fiber blanket and aluminum silicate fiber blanket lies in composition, performance and application.
The difference between ceramic fiber blanket and aluminum silicate fiber blanket in composition is as follows: ceramic fiber blanket is usually made of high-purity alumina, silicate and other ceramic materials; while aluminum silicate fiber blanket is mainly made of aluminum silicate fiber.
Ceramic Fiberboard VS ceramic fiber insulation blanket
| Ceramic Fiberboard | Ceramic fiber blanket | ||
| Density and texture | The density is relatively high, usually between 220-280 kg/m³, the texture is relatively hard and not easy to bend or fold. | The density is low, generally between 90-128 kg/m³, the texture is soft, and it has good elasticity and resilience. | |
| Usage scenarios | Due to its high hardness, it is suitable for applications that require a certain degree of rigidity, such as flat insulation layers, fire doors and fire curtains. | Because it is soft and foldable, it is suitable for occasions that require wrapping, winding or filling, such as pipe insulation, furnace door sealing and high-temperature flue lining. | |
| Thermal insulation effect | Due to its high density, although it has a certain thermal insulation effect, its ability to block hot air flow is slightly inferior to that of ceramic fiber blanket. | Due to its loose structure, it contains a large number of air gaps inside, which can effectively block hot air flow and has better thermal insulation performance. | |
| Price and Value | The price is usually higher, and due to its hardness, the construction and transportation are relatively complicated. | The price is relatively low, and the construction and transportation are relatively simple, so it has a higher cost-effectiveness in many applications. | |
| Chemical and thermal stability | Both have good chemical and thermal stability, but in specific applications, blankets may be more convenient in certain scenarios that require frequent adjustment or replacement due to their softness. | ||
Uses of Ceramic Fiber Blankets
- Industrial kilns: furnace door seals, furnace curtains, and high-temperature flues and air duct bushings and expansion joints of industrial kilns. It can also be used for high-temperature insulation and heat preservation of petrochemical equipment, containers, and pipelines.
- Transportation: Heat insulation and heat preservation of vehicles such as cars and trains improves the combustion efficiency of vehicles and reduces exhaust emissions.
- Construction: Heat insulation and heat preservation of buildings improves the energy efficiency of buildings and reduces energy consumption.
- Aerospace: With its excellent high temperature resistance and heat insulation performance, it has become an ideal choice for making insulation layers, thermal insulation layers, and fireproof layers in spacecraft structures and components. It can effectively protect spacecraft from damage such as high temperature, thermal radiation, and fire, ensuring the safe and stable operation of spacecraft.
