Aerogel Fiber Mat Drying Furnace

The Aerogel Fiber Mat Drying Furnace is an industrial-grade thermal processing equipment specially designed for the gel curing, drying, solvent removal, and atmospheric pressure drying processes of aerogel composite insulation mats (such as silica aerogel composites based on glass fiber, pre-oxidized fiber, ceramic fiber substrates, etc.).It is one of the key process equipment used in the transformation of aerogels from "wet gel" materials into high-performance super insulation products. Through precise temperature control, efficient moisture removal, and safe solvent evaporation, the equipment ensures the structural stability and excellent thermal insulation performance of aerogel products.

Applicable Standards

Due to the involvement of solvents (such as ethanol), high-temperature processes, and strict quality control requirements during aerogel production, the equipment and finished products generally need to comply with the following standards:

Product Performance Standard

GB/T 34336-2017 — Nano-Porous Aerogel Composite Insulation Products

Regulates the performance requirements of finished products, including thermal conductivity, density, and resilience.

Electrical Explosion-Proof Standard

GB/T 3836 Series — Explosive Atmospheres

Applicable to safety requirements in atmospheric drying processes involving the evaporation of flammable and explosive solvents such as alcohol.

Furnace Insulation Standard

GB/T 15316 — Design Specification for Insulation Engineering of Industrial Equipment and Pipelines

Specifies energy-saving and thermal insulation requirements for industrial drying equipment.

Main Features

High-Precision Temperature Control

The equipment adopts a PLC intelligent segmented temperature control system. Temperature accuracy can reach ±1℃ to ±2℃, preventing temperature fluctuations from damaging the nanoporous structure of aerogel materials.

Efficient Moisture Removal and Solvent Recovery

Equipped with negative pressure extraction and explosion-proof exhaust systems, it effectively removes moisture and organic solvents while ensuring safe operation.

Multiple Heating Methods Available

The equipment can adopt various heating technologies according to production requirements, including:

Microwave rapid drying technology (molecular-level internal heating, significantly reducing drying time)

Hot air circulation heating

Continuous tunnel drying process

Excellent Thermal Insulation Performance

The furnace body can also utilize aerogel insulation materials or other advanced insulation structures instead of traditional rock wool, greatly reducing heat loss and improving energy efficiency.

FAQ

Q1: What is the difference between an aerogel drying furnace and a conventional industrial oven?

A: Conventional industrial ovens usually have relatively basic temperature control and generally lack explosion-proof designs. The aerogel drying furnace provides high-precision temperature control (±1℃ to ±2℃), high-level explosion-proof electrical protection, and customized drying processes such as microwave heating or gradient temperature control. These features help prevent the collapse of aerogel nanopores during the drying process.

Q2: What types of substrates can be used for aerogel blanket drying?

A: The equipment can be widely used for drying various aerogel composite materials based on:

Glass fiber mats

Pre-oxidized fiber mats

Ceramic fiber paper or mats

High silica fiber mats

It is suitable for silica aerogel and carbon-based aerogel composite insulation materials.

Q3: Why is there an explosion risk during the aerogel drying process?

A: During atmospheric pressure drying, wet gels may contain large amounts of flammable volatile organic solvents, such as anhydrous ethanol and silicate ester compounds. During heating, these solvents evaporate rapidly. Without explosion-proof design and inert gas protection (such as nitrogen protection), the solvent concentration may reach the explosive limit and create safety hazards.

Q4: Which is better, microwave drying or hot air drying?

A: Microwave drying provides extremely high efficiency due to penetrating heating, which can significantly shorten drying time. However, the equipment investment cost is higher.

Hot air circulation and tunnel drying technologies are more mature, economical, and suitable for large-scale continuous production of thick aerogel blankets. The optimal solution depends on production capacity requirements and investment budget.

Q5: What temperature is usually required for the aerogel drying furnace?

A: The required temperature depends on the process stage.

During early-stage solvent removal or pre-drying under atmospheric conditions, the temperature is usually controlled slowly at around 20℃–40℃.

During final atmospheric curing and heat treatment, the temperature is generally increased and stabilized at approximately 170℃–190℃ to complete final shaping and performance improvement.
