Introduction
1. Standard Overview
GB/T 25041-2016 Glass Fiber Filter Material is a national standard of the People's Republic of China, applicable to woven filter cloth, needle felt filter material and ePTFE membrane filter material for dry dust collection and filtration produced with glass fiber as the main raw material. This standard was officially implemented on November 1, 2017, replacing the GB/T 25041-2010 version.
2. Background of Standard Revision and Technological Evolution
The main revisions to this standard include:
- Added technical indicators for ePTFE coated filter materials, especially the requirement for outlet dust concentration (≤0.5 mg/m³)
- Optimized the air permeability indicators of EWT F550, EWT F750, and EWT F750 A products in glass fiber bulked yarn filter cloth
- Deleted some tables and structural requirements for woven filter cloth in the old version
- Adjusted technical parameters such as tensile breaking strength and unit area mass of needle felt filter materials
3. Comparative Analysis of Standard Framework
| Standard Items | Old version (GB/T 25041-2010) | New version (GB/T 25041-2016） |
|---|---|---|
| Air permeability index | No specific requirements | Added air permeability range for EWT F550 and other products |
| Technical requirements for ePTFE membrane filter materials | Not involved | Added outlet dust concentration (≤0.5 mg/m³) |
| Test method | Refer to GB/T 5453 and other standards | Refer to ISO 11057 air quality test method |
4. Implementation Suggestions
Case Analysis: Application of ePTFE Coated Filter Material
Due to its excellent filtering performance, ePTFE coated filter material is widely used in the field of high-temperature dust removal. Special attention should be paid during implementation:
- Ensure that the technical indicators of the substrate meet the requirements (such as glass fiber diameter, tensile breaking strength)
- Strictly control the lamination fastness test (the film is not damaged after rubbing 30 times)
- Regularly monitor the outlet dust concentration to ensure that environmental protection requirements are met
5. Conclusion
The revision of GB/T 25041-2016 reflects the technological progress of my country's filter material industry and the emphasis on environmental protection. It is recommended that relevant companies update production standards in a timely manner and strengthen quality control to meet increasingly stringent environmental protection requirements.
