High-Performance Biosoluble Ceramic Fiber Paper

Product Overview

Compared with traditional ceramic fiber paper, Biosoluble Ceramic Fiber Paper not only maintains excellent heat resistance and thermal insulation performance, but also offers enhanced environmental degradability and occupational health safety. Its fiber structure can gradually dissolve in water environments, significantly reducing dust hazards during installation and use, while complying with mainstream international environmental standards.

The product is widely used in metallurgy, heat treatment, power generation, chemical processing, aerospace, and other industries. It is suitable for high-temperature equipment linings, insulation layers, fire barriers, and precision thermal management applications, making it one of the advanced materials promoting industrial energy efficiency and green manufacturing.

Enhanced through special processing technology, providing high tensile and tear strength to maintain integrity during manufacturing, transportation, and installation.

Chemical Corrosion Resistance

Resistant to most acidic and alkaline media, making it suitable for corrosive environments such as chemical and metallurgical industries.

Fire-Safe and Non-Toxic

Non-combustible material that releases no toxic or harmful gases under high temperatures, ensuring equipment and personnel safety.

Technical Parameters

Manufacturing Process Flow

Raw Material Selection and Preparation

High-purity alumina, silica, and other inorganic raw materials are carefully selected, proportioned, and pretreated to ensure composition uniformity and chemical stability.

High-Temperature Melting and Fiberization

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

Slurry Preparation and Homogenization

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

Wet Forming and Dewatering

The slurry is transferred to Fourdrinier or cylinder paper machines, where it is evenly distributed, vacuum dewatered, and pressed into wet fiber sheets.

Drying and Heat Setting

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

Surface Treatment (Optional)

Impregnation, coating, or calendering treatments can be applied according to customer requirements to provide additional properties such as waterproofing, reinforcement, or corrosion resistance.

Precision Slitting and Quality Inspection

The product is cut into specified dimensions through a tension-controlled slitting system, with each batch undergoing testing for thickness, density, strength, and solubility.

Packaging and Storage

Moisture-proof sealed packaging is used, with technical specifications and environmental labels clearly marked. Products are stored in temperature-controlled dry warehouses.

Packaging Display

SUNTHERM has a professional and experienced team capable of providing customized packaging solutions for various products across different industries.
