Introduction to the functional advantages of hard silica calcium stone insulation material for equipment? Hard calcium silicate insulation board is a high-performance inorganic hard insulation material, which is very suitable for insulation of high-temperature industrial equipment and pipelines, especially in industries such as glass, metallurgy, petrochemicals, and power.
Rosewool Insulation Refractory Co.,Ltd. Insulation Material's hard silicon calcium stone slab is a common thermal insulation material. The main raw materials of hard silicon calcium stone slab are calcium hydroxide and quartz sand, and the size can be customized according to usage needs. The finished hard silicon calcium stone slab can withstand high temperatures of 1050 ℃, with characteristics such as high temperature resistance, good insulation, high strength, fire insulation, etc. It is widely used in industries, construction, agriculture and other fields. What are the core functional advantages of hard calcium silicate?
1. Excellent temperature resistance performance
The maximum operating temperature of hard silica calcium silicate board can reach 1000-1050 ℃, far exceeding that of ordinary tobermorite type (650 ℃). 2. Low thermal conductivity, significant energy-saving effect
The thermal conductivity is usually ≤ 0.045-0.056 W/(m · K) (70-100 ℃). The porous structure of perovskite effectively suppresses heat conduction and convection, and the energy-saving rate in high-temperature fields has been measured to be up to 30% -50%. 3. Lightweight and high-strength, easy to construct
The bulk density can be as low as 170kg/m ³, greatly reducing equipment load. When the bulk density is similar, it has the highest strength among inorganic hard insulation materials and can be cut and drilled freely, making it suitable for the construction of irregular pipelines. 4. Safe and environmentally friendly, Class A non combustible
The material does not contain asbestos, formaldehyde, or radioactivity, and its combustion performance reaches A1 level. It is non combustible and does not produce toxic smoke when exposed to fire. 5. Good durability
Long term use without the powdering phenomenon similar to ceramic fiber felt, resistant to acid and alkali corrosion, not affected by moisture or insect damage, and has a long service life.
Introduction to the functional advantages of hard silica calcium stone insulation material for equipment? Rosewool Insulation Refractory Co.,Ltd. has a complete R&D, production, and sales system for hard silica calcium stone. When purchasing, it is recommended to directly provide the manufacturer with the specific working temperature, installation space dimensions, and whether there are special requirements such as oil and salt resistance of the equipment, in order to obtain the most accurate selection plan and comprehensive quotation.
