The Carbon Fiber Solvent Drying Tunnel Furnace is an industrial heating system specially designed for the efficient evaporation, drying, and pre-curing of solvents from the surface of materials during carbon fiber precursor production or composite material coating curing processes.Through a continuous tunnel-type structure, the equipment provides controlled heating conditions to remove water or organic solvents from carbon fiber materials, ensuring stable product quality and preparing materials for subsequent processing.

Applications

Carbon Fiber Precursor Sizing Drying

Used to remove moisture or organic solvents from sizing agents coated on the surface of carbon fiber precursor fibers.

Composite Material Coating Curing

Applied for continuous drying of surface coatings, impregnated resins, and other resin-based treatments on carbon fiber fabrics.

Prepreg Production

Used in the manufacturing process of carbon fiber prepreg tapes and prepreg fabrics to efficiently evaporate low-molecular-weight solvents and improve material performance.

Standards

The design, manufacturing, and operation of the equipment generally comply with the following standards:

GB/T 30790

Protective Paint Systems for Steel Structures — Protection Against Corrosion

Applicable to coating drying and curing process requirements.

GB 5226.1

Electrical Safety of Machinery — Electrical Equipment of Machines — Part 1: General Requirements

Specifies general electrical safety requirements for industrial machinery.

GB 20128

General Principles for Safety and Hygienic Design of Continuous Drying Equipment for Composite Materials

Provides safety and hygienic design requirements for continuous composite material drying equipment.

ISO 14644

Cleanrooms and Associated Controlled Environments

Applicable to drying systems requiring high cleanliness levels or controlled environmental conditions.

Features

Precise Temperature Control

The equipment adopts a multi-zone independent temperature control system with intelligent microcomputer PID regulation. Temperature variation can be controlled within ±1℃, ensuring stable drying conditions.

Explosion-Proof Safety System

Equipped with:

Organic solvent concentration monitoring system

Automatic exhaust ventilation system

Explosion-proof pressure relief doors

These systems effectively prevent safety risks caused by solvent evaporation.

Excellent Heating Uniformity

The equipment uses hot air circulation heating or far-infrared radiation heating technology to ensure uniform heating of carbon fiber materials without damaging the fiber structure.

High Efficiency and Energy Saving

The furnace body adopts high-density aluminum silicate fiber insulation materials, significantly reducing heat loss. The system can also support waste heat recovery from exhaust gases to improve energy efficiency.
