Anhui Yixiang Filter Materials: Dual Tech Advances in High-Temp Resistant Materials & Smart Production Lines Drive Dust Filter Bag Innovation
2025-07-14 09:23Anhui Yixiang Filter Materials: Technological Breakthroughs in Dust Filter Bags Lead Industry Upgrades, with Dual Advancements in High-Temperature Corrosion-Resistant Materials and Smart Production Lines
In the field of environmental protection equipment manufacturing, Anhui Yixiang Filter Materials Co., Ltd. has once again become a focal point of industry attention thanks to its continuous innovation in dust filter bag technology. In 2025, the company has established a comprehensive solution covering high-temperature, corrosion-resistant, and intelligent applications through material R&D, equipment upgrades, and process optimization. Its products stood out in the centralized procurement of dust filter bags by the Supply Chain Branch of Xinxing Ductile Iron Pipes Co., Ltd., marking recognition of its technological prowess by a leading enterprise.
Material Breakthroughs: From High-Temperature Resistance to Functional Composites
Yixiang Filter Materials has developed a three-tier technological system for its dust filter bag series—basic, high-end, and customized:
Core High-Temperature Corrosion-Resistant Materials:
PPS Composite Needle-punched Felt: Capable of continuous operation at 190°C with instantaneous temperature resistance up to 220°C, it excels in acid-alkali resistance and flexural strength, making it the top choice for high-temperature applications in steel and waste incineration sectors.
Basalt Fiber Filter Bags: Made entirely of basalt fiber, these bags combine efficient thermal insulation with sound absorption, achieving dust concentrations below 8 mg/m³ in cement kiln exhaust treatment—far exceeding China’s national standard of 50 mg/m³.
PTFE Membrane-Coated Needle-punched Felt: Utilizing ultra-low emission technology, it achieves a particle interception rate exceeding 99.97% for particles above 0.3 μm, maintaining stable emission concentrations below 8 mg/m³ in projects such as Tongling Conch Cement.
Functional Composite Innovations:
For complex industrial conditions in sectors like chemicals and printing, Yixiang’s R&D team developed a dual-coating technology combining anti-static and water-oil repellent properties, resolving adhesion issues caused by sulfur ammonium dust. In a welding workshop application at a Hefei automobile manufacturer, dust concentrations were reduced from 120 mg/m³ to 2 mg/m³, while extending filter bag lifespan to 3–5 years.
Equipment Upgrades: World-Class Production Lines Enable Efficient Manufacturing
In early 2025, Yixiang Filter Materials commissioned a 3 million m²/year production line for environmental dust filter bags, cementing its position as an industry leader:
Normal-Temperature Line: Equipped with Trützschler carders, Autefa cross-lappers, and Sanhui needle looms, it achieves full automation across fiber opening, web laying, and needling, boosting production efficiency by 40% and reducing weight deviation to ±2%.
High-Temperature Line: Adopts heat-resistant coating processes and intelligent temperature control systems, ensuring stable molding of PPS and basalt materials at 220°C, with a 15% improvement in temperature resistance compared to traditional methods.
Smart Inspection System: Integrates laser porosity analyzers and tension sensors for real-time monitoring of key metrics like air permeability and breaking strength, reducing defect rates to below 0.3%.
According to General Manager Han Guoqing, the project’s annual capacity of 5 million m² can meet the needs of 200 large industrial projects while creating over 80 jobs.
Process Optimization: From Standardization to Scenario-Based Customization
Yixiang Filter Materials implements a closed-loop management system of "pre-production-data feedback-process iteration" to align products with specific industrial conditions:
Modular Design: Standardized filter bag units (e.g., diameters of 130 mm and 160 mm) support rapid assembly and replacement, cutting equipment downtime by 60%.
Predictive Maintenance: Integrated with IoT platforms, 5G-enabled transmission of pressure differential and temperature data provides 72-hour advance warnings of bag damage, improving overall equipment efficiency by 40%.
Case Validation: In northern Anhui’s coal chemical base, corrosion-resistant PTFE filter bags resolved sulfur ammonium dust adhesion issues, while a Wuhu Haichuang Environmental Protection project achieved heavy metal dust recovery through specialized filter media, saving over RMB 2 million annually in raw material costs.
Market Recognition: Centralized Procurement by Industry Leaders Validates Technological Authority
In July 2025, Xinxing Ductile Iron Pipes Co., Ltd.’s Supply Chain Branch announced that Yixiang Filter Materials ranked first in two bidding categories—needle-punched filter media and high-temperature coated filter media—for its centralized dust filter bag procurement. The company’s technical proposal received high praise from the evaluation committee for its "balance of material temperature resistance, filtration efficiency, and cost." Additionally, Yixiang has established long-term partnerships with Maanshan Iron & Steel Group, Huainan Thermal Power Plant, and other enterprises, with products distributed across over 20 provinces nationwide.
Future Outlook: Driving Green Transformation Through Innovation
Yixiang Filter Materials is accelerating the development of an integrated ecosystem spanning "materials-equipment-services":
R&D Focus: Plans to allocate 8% of annual revenue to cutting-edge technologies like ultrafine fibers and nano-coatings, aiming to launch third-generation filter bags resistant to 300°C by 2026.
Production Advancements: Pursuing "lights-out factory" construction, leveraging AI vision inspection and robotic collaboration for fully unmanned operations.
Service Expansion: Launching a "Filter Bag Health Management" cloud platform to provide real-time monitoring, lifespan prediction, and replacement alerts, helping industrial clients reduce maintenance costs by over 30%.
From its roots in the "Hometown of Screen Mesh" to becoming a hub for environmental protection equipment manufacturing, Anhui Yixiang Filter Materials is propelling China’s industrial dust filtration technology toward efficiency, intelligence, and sustainability through technological innovation.
