Calcium silicate board products have become a key material in industrial plant wall enclosure, equipment lining, flue lining and other scenarios due to their excellent fire resistance and corrosion resistance. The core of product quality often depends on the production process. Many companies ask "What are the processes for producing calcium silicate board products for industrial plants?" Rosewool Insulation Refractory Co.,Ltd, as a source manufacturer with more than 30 years of experience in insulation and refractory fields, is not only proficient in various processes, but also uses innovative technology to create high-performance calcium silicate boards, providing reliable solutions for industrial enterprises. Comparison of mainstream processes for industrial calcium silicate board, Rosetexwool process is superior
The current industrial grade calcium silicate board products mainly include two types: atmospheric pressure hardening process and high-pressure steam curing process. Different processes determine the differences in product performance: Atmospheric pressure hardening process: The production cycle is long (about 7-10 days), the product density is low (≤ 1.2g/cm ³), and it is prone to deformation in high temperature and high humidity environments. It is only suitable for auxiliary areas with low requirements; High pressure steam curing process: It needs to be cured in a high-pressure environment of 180-200 ℃ and 1.2-1.5MPa. The product has high density (1.3-1.5g/cm ³) and high strength, but most manufacturers have uneven curing and poor batch stability due to equipment limitations. Rosetexwool breaks through the bottleneck of traditional craftsmanship and adopts a composite process of "high-pressure steam curing+precise temperature control shaping": firstly, silicon and calcium materials are mixed according to the optimal ratio, and special reinforcement fibers are added to enhance toughness. After being pressed and formed by molds, they are sent to a fully automatic temperature controlled high-pressure kettle, and the internal crystallization is ensured to be uniform through three-stage heating (50 ℃ preheating → 185 ℃ constant temperature curing → gradient cooling). Finally, 12 precision polishing treatments are carried out. This process stabilizes the product density at 1.4g/cm ³, with a flexural strength of 12MPa, far exceeding the industry average, and shortens the production cycle to 3-4 days, balancing performance and efficiency. Rosetexwool Calcium Silicate Board Products: Core Advantages for Adapting to Industrial Scenarios
Relying on advanced technology, the company's calcium silicate board products have demonstrated three core advantages in industrial scenarios: （1） High temperature and corrosion resistance, suitable for harsh environments
According to the testing conducted by the National Fire resistant Building Materials Quality Supervision and Inspection Center, the product has a fire resistance limit of 4 hours and will not deform or pulverize when continuously used at a high temperature of 800 ℃; At the same time, it has excellent corrosion resistance, with a strength loss of less than 5% after soaking in an acid-base solution with a pH value of 2-13 for 72 hours. It is perfectly suitable for strong corrosion and high temperature scenarios such as blast furnace flues in metallurgical plants and reactor liners in chemical plants. （2） High flatness for easy construction, reducing labor costs
Using high-precision polishing technology, the surface flatness error of the board is ≤ 0.5mm/m, and subsequent coating or pasting construction can be carried out directly without additional leveling treatment. For the irregular structure of industrial equipment, it supports customized cutting according to drawings with a cutting accuracy of ± 1mm. In a boiler renovation project of a power plant, the use of customized calcium silicate board increased construction efficiency by 40% and saved labor costs by 25%. （3） Environmentally friendly and radiation free, meeting the requirements of green industry
The raw materials used are natural quartz sand and food grade calcium carbonate, with zero formaldehyde and heavy metal emissions during the production process. The product has a radiation safety factor of ≤ 0.6 (national standard ≤ 1.0) and has passed the green building materials certification. Under the current demand for environmental protection renovation in industrial plants, it can help enterprises easily pass environmental inspection and avoid production being affected by material environmental issues. Choose Rosetexwool: Cooperation Guarantee from Source Manufacturers
For industrial enterprises, choosing calcium silicate board products is not only about selecting products, but also about choosing a stable supply chain and professional services. The manufacturer advantages of Rosetexwool provide protection for cooperation: （1） Adequate production capacity and guaranteed delivery
We have 4 fully automatic calcium silicate board production lines with an annual production capacity of 8 million square meters, equipped with a 20000 square meter finished product warehouse. The stock of regular specifications (1220 × 2440mm, 1200 × 3000mm) exceeds 100000 square meters, and emergency orders can be shipped within 72 hours. In a new energy plant expansion project, the company completed the delivery of 5000 square meters of calcium silicate boards within 3 days, ensuring the project is progressing on schedule. （2） Customized services tailored to actual needs
Establish a professional technical team of 10 people, who can customize exclusive formulas and sizes of calcium silicate board products based on the working parameters provided by customers (temperature, medium, installation space). I once customized a special calcium silicate board with a high temperature resistance of 1200 ℃ for a large refining enterprise, solving the problem that traditional materials cannot withstand extreme temperatures and obtaining long-term cooperation orders from customers. （3） High cost-effectiveness, more worry free cooperation
