High temperature resistant 1000 ℃ hard calcium silicate insulation board for industrial use "is an inorganic hard insulation material widely used in high-temperature industrial equipment and pipeline insulation, especially suitable for long-term working conditions in industries such as ceramics, glass, metallurgy, and petrochemicals where the temperature is close to or reaches 1000 ℃. The Hard Calcium Silica Insulation Board of Rosewool Insulation Refractory Co.,Ltd is a lightweight porous board mainly made of siliceous materials (such as quartz powder and diatomaceous earth) and calcareous materials (such as lime and carbide slag), which are synthesized by high-temperature and high-pressure hydrothermal reaction to produce Tobermorite or Xonotlite (Ca ₆ Si ₆ O ₁ ₇ (OH) ₂) as the main crystal phase. Functional characteristics of hard calcium silicate insulation board:
Good high-temperature stability: Long term use at 1000 ℃ without deformation or cracking, with stable structure.
High mechanical strength of microporous structure: Compared with aluminum silicate fiber felt or nano board, hard calcium silicate stone is more impact resistant and load-bearing, suitable for use as a support layer or outer protective layer.
Non toxic and environmentally friendly: It does not contain asbestos (modern technology has eliminated asbestos formulas), has no organic binders, and meets RoHS and industrial environmental requirements.
Easy to construct: sawable, studable, drillable, easy to cut into irregular parts, suitable for complex equipment structures.
High cost-effectiveness: In the temperature range of 800-1000 ℃, the comprehensive performance and cost are superior to some nano insulation materials.
Thermal stability and durability: The linear shrinkage rate is ≤ 1.0% under the condition of 1000 ℃ × 3h, the flexural strength is ≥ 0.35MPa, there is no powdering phenomenon during long-term use, and the service life is over 10 years, reducing replacement frequency and maintenance costs.
High temperature resistant 1000 ℃ hard calcium silicate insulation board, price influencing factors, density, temperature resistance level, specifications and sizes, and customized requirements (such as irregular cutting and anchoring) will affect the final quotation. It is recommended to directly contact the manufacturer for accurate quotation. It is a wise choice to cooperate with Rosewool Insulation Refractory Co.,Ltd for the demand of 1000 ℃ hard calcium silicate insulation board. We can provide multiple specifications of products and technical solutions to ensure that their products can achieve reliable insulation and energy-saving effects in industrial fields such as metallurgy, chemical industry, and ceramics. Rosewool Insulation Refractory Co.,Ltd will obtain precise selection suggestions based on specific equipment parameters.
