FAQ

Q1: How should the heating method of a fabric adhesive drying tunnel oven be selected?

A:The heating method mainly depends on the adhesive type:

Water-based adhesives: Hot air circulation heating is recommended because it provides effective moisture removal performance.

Solvent-based adhesives or applications requiring rapid surface curing: Far infrared heating is recommended due to its strong penetration ability and energy efficiency.

Special fast-curing applications: UV ultraviolet curing or microwave heating can be selected.

Q2: How does the equipment prevent explosion during drying of solvent-based adhesives?

A:The equipment must be equipped with:

Explosion-proof motors

Explosion-proof heating tubes

Independent exhaust ventilation systems

Continuous exhaust ventilation is used to dilute combustible gas concentrations inside the oven, keeping them far below the Lower Explosive Limit (LEL). Safety pressure relief ports are also installed to improve operational safety.

Q3: Why does the tunnel oven require segmented temperature control?

A:Segmented temperature control is required to meet the adhesive curing process curve. The oven is usually divided into:

Preheating zone: Removes moisture and solvents

Constant temperature zone: Promotes adhesive cross-linking and curing

Cooling zone: Reduces temperature and stabilizes the final product shape

This prevents problems such as excessive surface drying, internal bubbling, shrinkage, or cracking caused by improper heating.

Q4: What conveyor belt materials are available and how should they be selected?

A:Common conveyor options include:

PTFE (Teflon) Mesh Belt

High temperature resistance

Non-stick surface

Suitable for lightweight fabrics and adhesive-coated materials

Stainless Steel Mesh Belt

High load capacity

Long service life

Suitable for heavy industrial components

Roller Chain Conveyor

Suitable for special tray-based conveying systems and customized production processes

The selection depends on material weight, temperature requirements, and production conditions.

Q5: How can energy consumption be reduced during equipment operation?

A:Energy consumption can be reduced through:

Using high-quality high-density insulation materials (such as aluminum silicate wool) to minimize heat loss

Adopting hot air circulation and heat reuse designs

Using frequency converters to adjust fan speed and conveyor speed according to production capacity, avoiding unnecessary idle operation

The Fabric Adhesive Drying Tunnel Oven provides an efficient, precise, and safe continuous drying and curing solution for industries involving adhesive coating processes. With advantages such as accurate temperature control, flexible heating methods, explosion-proof safety design, and energy-saving operation, it is widely used in textile, electronics, packaging, automotive, and industrial manufacturing applications.
