Recently, the corrosion-resistant insulation boards independently developed and manufactured by Shijiazhuang Chenxing Industry Co., Ltd successfully passed rigorous testing by the National Refractory Materials Quality Inspection and Testing Center, with all performance indicators meeting national standards. This outcome signifies authoritative recognition of the products reliable quality and superior performance.
Core Technology Analysis of Corrosion-Resistant Insulation Boards
The corrosion-resistant insulation board is a new multifunctional building material integrating corrosion resistance and thermal insulation properties. Manufactured using natural expanded vermiculite as the primary raw material, combined with organic materials in specific proportions, it is formed through a high-temperature, high-pressure pressing process. As a silicate mineral, expanded vermiculite possesses a unique flake-like layered structure that endows the product with exceptional chemical corrosion resistance, effectively withstanding the erosion of most chemical corrosive substances.
Outstanding Performance of Corrosion-Resistant Insulation Boards
The testing center evaluated key properties of corrosion-resistant insulation boards, including bulk density, compressive strength at room temperature, flexural strength at room temperature, linear shrinkage rate, thermal conductivity, and loss on ignition. The boards demonstrated a density of 1253 kg/m³, with compressive strength reaching 11.94 MPa and flexural strength at 8.27 MPa—significantly exceeding specified standards. Thermal conductivity (hot face temperature 800±25°C) ≤0.298; LOI (1025°C) ≤3.89. Content levels of SiO₂, Al₂O₃, MgO, and other components were also tested, with all indicators meeting standards. Beyond high resistance to most chemical corrosives, the corrosion-resistant insulation board offers advantages including high strength, low thermal conductivity, excellent thermal stability, minimal deformation, resistance to powdering, and ease of installation.
Wide Range of Applications
Leveraging its superior performance, the corrosion-resistant insulation board is widely applicable in chemical plant insulation and equipment protection, marine engineering corrosion prevention and insulation, power facility insulation and protection, specialized storage building insulation, and other industrial scenarios requiring corrosion-resistant insulation.
