In the high-temperature conditions of cement production, the selection and correct use of insulation materials are directly related to equipment operating efficiency and enterprise cost control. As the preferred product for insulation and refractory materials in the cement industry, silicate insulation ceramic fiber blanket has become the "insulation guardian" of core equipment such as kilns, pipelines, and preheaters due to its excellent high temperature resistance, low thermal conductivity, and wear resistance. However, many cement plants fail to fully utilize their performance advantages due to unfamiliarity with the correct usage methods after procurement. Today, Rosewool Insulation Refractory Co.,Ltd, based on years of industry experience, will explain in detail the key points of using silicate thermal insulation ceramic fiber blankets to help enterprises achieve efficient insulation, cost reduction and efficiency improvement. Introduction Ceramic fiber blanket
Ceramic fiber blanket has excellent specialties of low thermal conductivity, good heat stability, thermal shock resistance and tensile strength, good thermal insulation, fire proof and noise reduction. It is widely used in power generation, iron and steel, aluminum/n-ferrous metals, glass, ceramics, aerospace, super alloys, petrochemical, semiconductors, cement, automotive, domestic appliances etc. Temperature level is 1100-1430℃ (2012℉--2600℉).

1、 Before use: Make preparations to ensure that the basic conditions meet the standards
Before using silicate insulation ceramic fiber blanket, it is necessary to conduct a comprehensive inspection and treatment of the construction site, which is the basis for ensuring the insulation effect. Firstly, clean the dust, oil stains, rust and other impurities on the surface of the equipment. If there are cracks or depressions on the surface, special repair materials need to be used to fill them flat - uneven surfaces can cause the fiber blanket to not fit tightly with the equipment, forming gaps and causing heat loss. Secondly, according to the equipment size and insulation requirements, a cutting plan should be planned in advance: Rosewool's silicate insulation ceramic fiber blanket can be customized according to customer needs, but special cutting tools need to be used during on-site cutting to ensure neat cuts and avoid material waste caused by improper cutting. At the same time, construction personnel need to wear specialized protective equipment, such as heat-resistant gloves, dust masks, etc., to protect personal safety and avoid fiber impurities affecting construction quality. 2、 During construction: Master paving techniques to ensure proper fit and sealing
Laying is the core process of using silicate insulation ceramic fiber blanket, and the correct laying method can maximize its insulation performance. For curved or irregular parts such as the inner wall of the kiln and the outer wall of the pipeline, the "staggered laying" method should be used: the joints of adjacent fiber blankets should be staggered to avoid longitudinal through seams. The joints should be firmly bonded with high-temperature adhesive, and if necessary, fixed with high-temperature resistant steel wire mesh to prevent the fiber blankets from shifting under high temperature. When laying, attention should be paid to moderate force, ensuring that the fiber blanket is tightly adhered to the equipment surface and avoiding excessive compression that may damage the fiber structure and affect the insulation effect.
For different temperature zones, the number of laying layers also needs to be flexibly adjusted: in the high-temperature zone of the kiln with a temperature higher than 1200 ℃, it is recommended to lay 2-3 layers of fiber blankets, and apply a thin layer of high-temperature adhesive between each layer to enhance the overall integrity; In pipelines or equipment casings with lower temperatures, 1-2 layers can meet the insulation requirements. Rosewool reminds that the joint width should be strictly controlled during the construction process, generally not exceeding 5mm. If the joint is too large, it needs to be filled with fiber strips of the same material to ensure no heat leakage channels. 3、 After construction: Take good care of protection and maintenance to extend the service life
After the installation of silicate insulation ceramic fiber blanket, it is not a one-time solution, and subsequent protection and maintenance are equally important. Firstly, apply high-temperature resistant protective coating on the surface of the fiber blanket. This coating not only enhances the fiber blanket's resistance to wear and dust erosion, but also prevents fiber detachment and extends the product's service life. In the high dust environment of cement production, unprotected fiber blankets are easily penetrated by dust, leading to a decrease in insulation performance. Secondly, regular inspections should be conducted on the insulation layer. If local damage, detachment, or joint cracking is found, specialized materials should be used to repair it in a timely manner.
It is worth noting that the silicate thermal insulation ceramic fiber blanket of Rosewool has excellent anti-aging performance. Under normal maintenance, the service life can reach 5-8 years, far higher than similar products in the industry. But to ensure long-term stable insulation effect, it is recommended to conduct a comprehensive inspection once a year and carry out local maintenance or replacement according to the actual situation. 4、 Choosing the right product and using it correctly, Rosewool provides full assistance throughout the process
