Aluminum film non-woven fabric is a new type of material that adopts advanced production processes and technologies, and has many advantages. It is widely used in various fields, such as construction, medical, furniture, packaging, etc. This article will introduce the structure and production process of aluminum film non-woven fabric, as well as the product advantages.
1, The structure of aluminum film non-woven fabric
Aluminum film non-woven fabric is a three-layer structure material composed of non-woven fabric, aluminum foil, and melt blown fabric.
1. Non woven fabric layer: The non-woven fabric layer is the first and outermost layer of aluminum film non-woven fabric. The non-woven fabric layer has good air permeability, water resistance, tear resistance and aging resistance, which can effectively protect the inner aluminum foil and melt blown fabric.
2. Aluminum foil layer: The aluminum foil layer is the second and most important layer of aluminum film non-woven fabric. The aluminum foil layer has good thermal insulation and moisture resistance, which can effectively isolate external heat and moisture, and maintain the temperature and humidity of the inner layer.
3. Melt blown fabric layer: The melt blown fabric layer is the third and inner layer of aluminum film non-woven fabric. The melt blown fabric layer has good filtering and protective properties, which can effectively filter out impurities and particles, protecting the aluminum foil layer from damage.
2, The production process of aluminum film non-woven fabric
The production process of aluminum film non-woven fabric mainly includes the following steps:
1. Raw material preparation: Non woven fabric, aluminum foil, and melt blown fabric are the three main raw materials for aluminum film non-woven fabric. Non woven fabrics generally use two materials: polypropylene (PP) and polyester (PET), aluminum foil generally uses pure aluminum material, and melt blown fabrics generally use polymer material.
2. Non woven fabric composite: The non-woven fabric and aluminum foil are combined through a composite machine to form a layer of aluminum foil non-woven fabric.
3. Melt blown fabric spraying: Spray the meltblown fabric through a meltblown machine to form a layer of meltblown fabric.
4. Aluminum foil non-woven fabric composite: Melt blown fabric and aluminum foil non-woven fabric are combined through a composite machine to form a layer of aluminum film non-woven fabric.
5. Roll forming: The aluminum film non-woven fabric is rolled into different specifications and sizes through a coiling machine.
3, Advantages of aluminum film non-woven fabric products
Aluminum film non-woven fabric has the following advantages:
1. Good thermal insulation and moisture resistance: The aluminum foil layer has good thermal insulation and moisture resistance, which can effectively isolate external heat and moisture, and maintain the temperature and humidity of the inner layer.
2. Good breathability and waterproofing: The non-woven fabric layer has good breathability and waterproofing, which can prevent water and pollutants from infiltrating.
3. Good filtration and protection: The melt blown fabric layer has good filtration and protection, which can filter out impurities and particles, and protect the aluminum foil layer from damage.
4. Easy to process and use: Aluminum film non-woven fabric is easy to process and use, and can be cut and spliced according to different needs. It can also be composite with other materials to form more complex materials.
5. Environmental safety: Aluminum film non-woven fabric is made of environmentally friendly materials, which have good safety and reliability and will not cause any harm or pollution to the environment and human health.
In summary, aluminum film non-woven fabric is a very practical material with many advantages and can be widely used in various fields. I believe that in the near future, it will become an important component in the field of materials, serving people's needs
