Recently, the SCR denitrification project site of a large cement plant in Chongqing was busy. The transportation fleet of Rosewool Insulation Refractory Co.,Ltd. arrived on time, loaded with high-performance aluminum silicate fiber blankets, and completed delivery. This batch of products will be used for the insulation and heat insulation of SCR reactors, laying a key defense line for the stable operation of the project and once again confirming Rosewool's strong strength and reliable reputation in the field of insulation and refractory materials.
As the core insulation material of the SCR project in the cement plant, Rosewool aluminum silicate fiber blanket has irreplaceable performance advantages. Firstly, it has excellent high-temperature resistance and can work stably in a high-temperature environment of 1260 ℃ for a long time, fully adapting to the high-temperature conditions of SCR reactor operation, effectively blocking heat loss and reducing energy consumption; Secondly, the product has an extremely low thermal conductivity, which can build an efficient insulation layer, reduce equipment heat loss, help cement plants further optimize their energy consumption structure, and meet the current development needs of green production; Furthermore, the fiber blanket has a flexible texture and is easy to construct. On site workers only need to cut it to fit the irregular structure of the equipment, greatly shortening the construction period and reducing labor costs. In addition, the product also has excellent chemical stability, which can resist the corrosion of flue gas in SCR systems, extend the service life of equipment, and provide guarantees for the long-term stable operation of the project. What are the advantages of aluminum silicate needle punched blanket
Aluminum silicate needle punched blanket, as a high-performance inorganic insulation material, is widely used in industrial insulation, building fire prevention, equipment insulation and other fields due to its unique production process and material characteristics. Its core advantages can be developed from the following six dimensions: 1、 Excellent insulation performance and outstanding energy consumption control ability
The thermal conductivity of aluminum silicate needle punched blanket is extremely low, usually ≤ 0.034W/(m · K) at room temperature (25 ℃), and it can still maintain stable insulation effect in high temperature environments (such as 800-1200 ℃). This feature enables it to effectively block heat transfer, whether it is the outer wall insulation of industrial kilns and boilers, or the insulation layer of building exterior walls, it can significantly reduce heat loss, help enterprises reduce energy consumption, lower operating costs, and assist buildings in achieving energy-saving indicators. 2、 Excellent high temperature resistance and fire resistance, high safety factor
This material is made of high-quality aluminum silicate fiber as raw material, with a maximum operating temperature of 1400 ℃ (divided into ordinary type, high-purity type, high aluminum type, etc. according to the material model, with a temperature resistance range covering 600-1400 ℃), and belongs to non combustible materials (with combustion performance reaching Class A). In extreme scenarios such as fires, it does not burn or release toxic or harmful gases, and can form a stable fire barrier, effectively delaying the spread of fire and providing reliable safety guarantees for industrial production workshops, high-rise building fire zones, and other scenarios. 3、 Good chemical stability and strong corrosion resistance
Aluminum silicate needle punched blanket has excellent chemical inertness, and can withstand corrosive gases (such as sulfur dioxide, nitrogen oxides), steam, and liquid erosion in most industrial environments, except for strong acids and bases (such as concentrated hydrochloric acid, hydrofluoric acid). In highly corrosive fields such as chemical engineering and metallurgy, using this material as an insulation layer for equipment can avoid insulation failure caused by material corrosion, extend the service life of equipment and the maintenance cycle of insulation systems. 4、 Lightweight and flexible structure, easy to construct and install
Compared with traditional block thermal insulation materials (such as rock wool board and foam glass), aluminum silicate needle blanket is light in texture (volume density is usually 90-120kg/m ³), and has good flexibility and tensile strength. It can be cut, rolled or spliced according to construction needs. Whether it is complex shaped pipelines, kiln surfaces, or large areas of walls and roofs, they can tightly adhere to the base layer, reduce construction gaps, and lower the difficulty of handling and labor costs during the construction process. 5、 Low shrinkage rate and dimensional stability, ensuring long-term insulation effect
In long-term high-temperature environments, aluminum silicate needle punched blankets can effectively suppress fiber shrinkage through special needle punching technology and fiber interweaving structure, with a high-temperature shrinkage rate usually ≤ 3% (at rated operating temperature). This feature can avoid cracking and detachment of the insulation layer caused by material shrinkage, ensuring that the insulation system maintains a complete structure for a long time and reducing the frequency of later maintenance. It is especially suitable for industrial equipment, high-temperature pipelines, and other scenarios that operate for a long time. 6、 Environmentally friendly and pollution-free, meeting the needs of green development
Aluminum silicate needle punched blanket does not contain toxic and harmful substances such as asbestos and formaldehyde, and will not cause environmental pollution during production, use, and disposal. Some models of materials can be recycled and reused, which is in line with the current development trend of "green production" in the industrial field and "low-carbon environmental protection" in the construction field. Meanwhile, its excellent insulation performance can indirectly reduce carbon emissions caused by energy consumption, providing assistance for enterprises to achieve environmental protection goals. Rosewool, as a strong manufacturer deeply engaged in the field of insulation and refractory materials for many years, not only has advanced production equipment and standardized production workshops, but also has established a sound quality control system. From raw material screening to finished product delivery, each roll of aluminum silicate fiber blanket undergoes strict testing to ensure that all performance indicators meet the standards. At the same time, the company is equipped with a professional technical team that can provide customized solutions according to the actual needs of the project, from product selection to on-site construction guidance, providing full protection for customers throughout the process.
Choosing to cooperate with Rosewool is a guarantee of multiple benefits for customers. On the one hand, the manufacturer's direct supply model eliminates intermediate links and can provide customers with cost-effective products, reducing procurement costs; On the other hand, the company has an efficient logistics distribution system that can accurately plan delivery times based on project progress, ensuring timely delivery of materials and avoiding delays in supply that may affect project progress. In addition, a comprehensive after-sales service system ensures that customers have no worries. Whether it is technical questions during product use or subsequent replenishment needs, Rosewool can quickly respond and safeguard cooperation.
The smooth supply of SCR project for Chongqing Cement Plant this time is not only a recognition of the quality of Rosewool's aluminum silicate fiber blanket by the customer, but also a recognition of the company's comprehensive service capabilities.
