Preoxidized silk-composite aluminum foil fabric用于暖通空调系统中的管道保温

The pre-oxidized silk-aluminum foil nonwoven fabric combines the flame-retardant, fire-resistant, and high-temperature-resistant properties of pre-oxidized silk with the heat-radiation-reflection capabilities of metallic aluminum foil. Utilizing a composite structure, it features a pre-oxidized silk needle-punched nonwoven fabric as the foundational framework, which is tightly bonded with a high-purity aluminum foil layer through advanced processes such as high-temperature heating—resulting in a composite material system that is both flexible and exceptionally durable.

Characteristics of pre-oxidized silk-composite aluminum foil non-woven fabric:

1. Flame Retardancy and Thermal Insulation

In terms of thermal insulation performance, pre-oxidized silk nonwoven fabric boasts excellent heat-retention and insulation properties. The aluminum foil layer on one side effectively reflects radiant heat, significantly reducing heat transfer. This unique feature enables the material to maintain a relatively stable internal temperature even in high-temperature environments, providing reliable protection for equipment or personnel.

2. Excellent mechanical strength and durability

With high tensile strength and exceptional tear resistance, the material maintains its shape and resists damage under stress, making it ideal for use as protective outer layers or packaging materials—capable of enduring significant mechanical stress without cracking, thus ensuring consistent protection over time. Additionally, a strong bond is formed between the aluminum foil layer and the pre-oxidized fiber base fabric, preventing the aluminum foil from peeling off or cracking easily. Even after repeated rubbing, the material remains intact and undamaged.

3. Excellent chemical resistance and weatherability

The pre-oxidized silk-composite aluminum foil nonwoven fabric can withstand a wide range of indoor and outdoor environmental conditions without rapidly degrading due to temperature fluctuations or UV exposure. It also boasts exceptional sealing performance, being completely impermeable to both air and water, effectively preventing the intrusion of moisture, vapor, and other corrosive substances. This comprehensive environmental resilience makes the pre-oxidized silk-composite aluminum foil fabric ideal not only for indoor use but also capable of providing long-lasting, reliable protection outdoors—even under extreme climatic conditions.

Applications of pre-oxidized silk-composite aluminum foil non-woven fabric:

1. Firefighting and Personal Protective Equipment Field

Used for manufacturing professional firefighting equipment, including fire suits, fire-resistant gloves, smoke-proof hoods, and more. In these applications, the material effectively blocks flames and intense thermal radiation, providing critical life protection for firefighters and personnel working in high-temperature environments. Notably, this material is often employed in key reinforcement areas of fire suits—such as the shoulders, front plackets, and other vulnerable or high-risk zones—enhancing the overall protective performance and extending the service life of the garments.

In addition, the pre-oxidized silk-aluminum foil fabric is also used in personal protective equipment for various industrial environments. In workplaces such as welding and metal processing—areas prone to sparks and high-temperature splashes—this material can be employed to create protective curtains, fireproof blankets, and specialized protective garments, effectively blocking sparks and molten debris to prevent burns and fire hazards. Meanwhile, thanks to its outstanding cut-resistant properties, this material can also be utilized in manufacturing high-risk work environment gloves, offering both flame-retardant protection and safeguarding against mechanical injuries.

2. Industrial Insulation and Protection Field

Pre-oxidized silk-composite aluminum foil nonwoven fabric is the ideal material for pipe insulation in HVAC systems, effectively preventing heat loss while also blocking moisture vapor, ensuring the long-term efficiency of the insulation system. Additionally, its outstanding reflective performance minimizes radiative heat transfer, boosting energy efficiency and helping organizations achieve their energy-saving and emission-reduction goals.

In the petrochemical industry, it is commonly used for protective wrapping of chemical equipment such as oil transportation pipelines and steam pipes, providing multi-layered protection against flame retardancy, corrosion resistance, and thermal insulation.

In the construction field, pre-oxidized fiber-reinforced aluminum foil fabric is used as a soundproofing and thermal insulation material. Thanks to its air- and water-tight properties, it effectively enhances a building's energy efficiency and acoustic comfort.

In industrial packaging, this material can also be used for moisture-proof, anti-fog, fire-resistant, and corrosion-proof wrapping of export equipment—making it especially ideal for safeguarding high-value devices and instruments that are sensitive to humidity and corrosion.
