Aluminosilicate products are refractory insulation materials primarily composed of aluminum silicate. They are widely used in industrial furnaces, pipeline insulation, and high-temperature equipment. To ensure product quality and stable performance, my country has established strict implementation standards to regulate their production and application.
Currently, the main implementation standards for aluminum silicate products include GB/T 16400-2015, "Aluminum Silicate Wool and Its Products for Thermal Insulation," and YB/T 4130-2015, "Aluminum Silicate Refractory Fiber Products." GB/T 16400 applies to aluminum silicate wool and its processed products for thermal insulation purposes, such as felt, boards, and pipe shells. Key technical specifications include fiber diameter, shot content, thermal conductivity, density, and operating temperature. For example, the operating temperature of ordinary aluminum silicate wool is typically 1000-1200°C, while high-purity products can reach 1400°C. YB/T 4130 sets higher requirements for tensile strength, shrinkage, and chemical stability for refractory fiber products used in high-temperature environments such as industrial furnaces.
In addition, industry standards such as JC/T 892-2010 "Refractory Fiber Products" and ASTM C892 (American Society for Testing and Materials) are often referenced for export or high-end applications. These standards clearly define product dimensional tolerances, appearance quality, and combustion performance, ensuring structural stability and minimizing heat loss in high-temperature environments.
Strict implementation of these standards not only ensures the performance and reliability of aluminum silicate products but also provides users with a basis for selection. Companies should strictly adhere to these standards and obtain third-party testing and certification to ensure their products meet market requirements. In the future, as technology advances, these standards may be further optimized to meet even higher energy-saving and environmental protection demands.
