The improvement in the safety performance of Needle Punched Nonwoven Fabric in special environments is mainly reflected in a series of improvements and optimizations made to meet specific environmental requirements.
1. Improvement of flame retardant performance
Application of flame retardants:
Needle Punched Nonwoven Fabric significantly improves its flame retardant performance by adding flame retardants. Flame retardants can be divided into physical flame retardants and chemical flame retardants. Physical flame retardants mainly achieve flame retardant effects by increasing the density of materials and reducing the burning speed; while chemical flame retardants achieve flame retardant effects by adding specific chemicals to the materials to inhibit the spread of flames when burning.
There are various ways to add flame retardants, such as dissolving the flame retardant in water and soaking the Needle Punched Nonwoven Fabric, or spraying the flame retardant directly on the surface of the material and drying it to ensure that the flame retardant fully penetrates into the material.
Flame retardant effect and advantages:
Flame retardant Needle Punched Nonwoven Fabric can significantly slow down the spread of flames when burning, and can even self-extinguish in some cases, thereby greatly reducing the risk of fire.
Flame retardant treatment has little effect on other physical properties of Needle Punched Nonwoven Fabric, such as strength, elasticity and other properties remain basically unchanged.
2. Improvement of oil resistance
Oil resistance treatment process:
Needle Punched Nonwoven Fabric is treated with special processes, such as coating with oil-proof coating or surface modification, so that it has excellent oil resistance.
Oil-proof coating can effectively prevent grease from penetrating into the material, keeping the material clean and dry.
Application scenarios and advantages:
Oil-proof Needle Punched Nonwoven Fabric is widely used in environments such as food processing and petrochemicals that need to prevent grease pollution.
Its oil-proof performance can ensure that the material maintains stable performance during long-term use and prolongs its service life.
3. Improvement of waterproof performance
Waterproof treatment process:
Waterproof Needle Punched Nonwoven Fabric usually achieves waterproof effect by coating with waterproof membrane or special coating treatment.
The waterproof membrane can fit tightly on the surface of the material to form an effective waterproof barrier to prevent water penetration.
Application scenarios and advantages:
Its excellent waterproof performance can ensure that the material can maintain stable performance in a humid environment, while having good air permeability and durability.
4. Improvement of comprehensive performance
Multifunctional composite treatment:
In response to the needs of special environments, Needle Punched Nonwoven Fabric can also be multifunctionally composited, such as achieving flame retardant, oil-proof, waterproof and other properties at the same time.
This composite treatment requires comprehensive consideration of the mutual influence and balance between various properties to ensure that the material can maintain stable performance in a complex environment.
Environmental protection and sustainability:
While improving the safety performance of Needle Punched Nonwoven Fabric, it also pays attention to environmental protection and sustainability. For example, choose non-toxic and environmentally friendly flame retardants and oil-proof agents; use recyclable or biodegradable materials for production, etc.
The improvement of the safety performance of Needle Punched Nonwoven Fabric in special environments is mainly reflected in flame retardant, oil-proof, waterproof and other aspects. By adopting advanced processing technology and environmentally friendly materials, Needle Punched Nonwoven Fabric can maintain stable performance in complex environments, providing safer and more reliable protection for people's production and life.
