Technical Parameters

Production Process Flow

Raw Material Selection and Formulation

High-purity inorganic raw materials such as alumina and silica are selected, strictly proportioned, and pre-treated to ensure compositional uniformity and chemical stability.

High-Temperature Melting and Fiberization

Raw materials are melted at temperatures above 2000°C in electric arc or resistance furnaces, then formed into continuous inorganic fibers through high-speed centrifugal spinning or blowing processes.

Slurry Preparation and Homogenization

The fibers are dispersed into a slurry, mixed with environmentally friendly binders and functional additives, and homogenized through high-speed stirring to form a uniform and stable fiber slurry.

Wet-Forming and Dewatering

The slurry is transferred to a long-net or round-net papermaking machine, where it is evenly spread, vacuum-dewatered, and pressed to form a thin wet fiber layer.

Drying and Thermal Setting

The wet sheets pass through a multi-stage temperature-controlled drying system to remove moisture, followed by high-temperature heat treatment for structural setting and crystalline phase transformation.

Surface Treatment (Optional)

Depending on requirements, treatments such as impregnation, coating, or calendering are applied to provide additional functionalities like waterproofing, reinforcement, or corrosion resistance.

Precision Cutting and Quality Inspection

The material is cut to specified dimensions using a tension-controlled cutting system, with each batch undergoing tests for thickness, density, strength, and solubility.

Packaging and Storage

The product is packaged in moisture-proof and sealed packaging, labeled with technical parameters and environmental certifications, and stored in a temperature-controlled, dry warehouse area.
