High Purity Aluminum Foil Ceramic Fiber Needle Punched Blanket

1. Product Introduction

Aluminum foil ceramic fiber blanket has the advantages of high temperature resistance, low thermal conductivity, good thermal stability and chemical stability of ceramic fiber blanket, and also has the advantages of high reflectivity, moisture resistance and dust resistance brought by the aluminum foil layer. It is a multifunctional material integrating heat insulation, heat preservation and protection. It is widely used in thermal energy management and energy-saving insulation systems of high-temperature equipment such as metallurgy, electricity, petrochemical, building materials, and ships.

2. Main performance characteristics

① Excellent thermal insulation performance

Ceramic fiber itself has low thermal conductivity and small heat capacity. It can be used for a long time in a high temperature environment, effectively reducing the furnace shell temperature and improving energy efficiency.

② Excellent heat reflection performance

The aluminum foil surface has a reflectivity of more than 96% for infrared heat radiation, which effectively blocks the loss of heat radiation and enhances the insulation effect.

③ Moisture and dustproof

The aluminum foil layer has moisture-proof, waterproof and dust-proof functions, which can prevent water vapor, oil stains, dust and other erosions on the ceramic fiber body and extend the service life of the material.

④ High mechanical strength and easy installation

The ceramic fiber blanket body treated by double-sided needle punching process has good tensile strength and flexibility, and is not easy to break during construction; the aluminum foil layer is firmly attached, which is convenient for cutting, wrapping, winding and other installation methods.

⑤ Sound absorption and noise reduction

The porous structure of ceramic fiber has good sound wave absorption ability, and the aluminum foil layer can effectively block industrial noise, which helps to improve the comfort of the working environment.

⑥ Environmentally friendly

It does not contain asbestos, no harmful substances are released, no harm to human health, and meets the requirements of the EU RoHS environmental protection directive.

4. Product structure and type

Aluminum foil ceramic fiber blanket is usually a single-sided attachment structure, that is, one side is an aluminum foil layer and the other side is an exposed ceramic fiber blanket. Common bonding methods are:

Thermal bonding: The aluminum foil is bonded to the fiber blanket by hot pressing, which is firmly bonded and has excellent high temperature resistance.

Adhesive lamination: A special high-temperature adhesive is used to bond the aluminum foil, which is suitable for applications with low strength requirements.

Aluminum foils of different thicknesses and strengths (7μm~50μm) and different types of ceramic fiber blankets (standard, high-purity, zirconium-containing, polycrystalline mullite, etc.) can be selected according to customer needs.

5. Main application areas

Insulation layer for high-temperature equipment such as industrial heat treatment furnaces, heating furnaces, ceramic kilns, etc.

The aluminum foil layer can effectively reflect heat radiation and improve the overall insulation efficiency.

Insulation coating for high-temperature pipes and chimneys

It has good winding performance and wind erosion resistance, which can extend the service life of the equipment.

Noise control system for power equipment (such as gas turbines, engines, etc.)

The porous fiber structure absorbs sound, and the aluminum foil reflects sound waves, providing double noise reduction protection for industrial equipment.

Fireproof and heat-insulating lining for shipbuilding, aviation, and automobile industries

Meets the comprehensive requirements of lightweight, high temperature resistance, heat insulation and shock absorption.

Thermal insulation layer in building energy-saving insulation system

Especially suitable for roof insulation systems and curtain wall fire protection systems that require reflection of heat radiation.

Fire protection for electrical equipment and control cabinets

It has a high fire rating and can be used as a safe isolation material for high-temperature electrical equipment.
