Detailed Description
Industrial filter cloth, other equipment, application in the fiberboard industry
Filter type: Other equipment
Application industry: Fiberboard
Analysis of the application of industrial filter cloth in multiple equipment in the fiberboard industry
—— From wet process to environmental governance, the key supporting role of filter media
With the continuous growth of building decoration, home manufacturing, and green building materials demand, fiberboard ( Fiberboard ) as a type of man-made board material, is becoming increasingly widely used worldwide. Especially in China, the fiberboard industry has formed a complete industrial chain, from raw material pretreatment to board forming, drying, pressing, and finishing. Each process places higher demands on equipment performance and operational stability.
Behind these complex and continuous processes, there is an often overlooked but crucial “ behind-the-scenes role ”—— industrial filter cloth and filter mesh 。It is not only used in the traditional sense of solid-liquid separation, but also supports wet process fiber separation, slurry concentration, white water recovery, flue gas treatment, wastewater filtration, waste gas desulfurization and dust removal, and other aspects ，becoming a key material for improving board quality, reducing emission costs, and achieving green production.
This article will systematically sort out the equipment and processes related to filtration in the main production stages of the fiberboard industry, analyze the core application of industrial filter cloth in these processes, and, combined with typical enterprise practices, demonstrate its value in improving production capacity and environmental performance.
I. Brief description of fiberboard production process: From wood raw materials to high-strength board materials
Fiberboard is divided into wet process fiberboard ( Hardboard ) and dry process fiberboard ( MDF ，medium-density fiberboard) ，both of which use plant fibers such as wood chips, sawdust, and bagasse as raw materials, processed through processes such as thermal grinding of fibers, forming and laying, hot pressing, cutting, and curing.
Among them, wet process fiberboard after thermal grinding, the fibers need to be diluted with a large amount of water before forming, producing a large amount of white water recycling system and slurry filtration processes, with heavy filtration tasks.
And dry process fiberboard although the moisture content is relatively low, it also involves adhesive spraying and recovery, waste gas dust removal and desulfurization, and wastewater filtration in multiple stages, and still relies heavily on the support of the filtration system.
II. Technological Trends: Customized Filter Cloth Solutions to Promote Green Upgrades
Xiamen Citius (Xiamen Citius) can research and produce various special-performance monofilament materials according to different application conditions of customers. These materials include: ordinary and highly hydrolysis-resistant PET 、 PA （ PA6、PA66、PA610、PA11、PA12 etc.）、 PP （including high-temperature resistant PP ）、 PPS 、 PEEK ，core-shell materials ( PA/PET、PPS/PET ）。These materials have broadened the application fields of Xiamen Citius (Xiamen Citius) Company products and solved the requirements of customers for filtration materials in special working conditions.
Xiamen Citius (Xiamen Citius) After nearly 30 years of continuous research and development, the company can provide customers with solutions for filtration materials in solid-liquid separation processes, and its research level is leading in China. Xiamen Citius (Xiamen Citius) Company has a technical team with many years of experience in filtration material research, and has the most complete filtration material research, testing, and pilot production line in China. It can provide customers with customized and personalized services.
As the fiberboard industry moves towards energy saving, clean, and automated development, the role of filter media is no longer simply “ filtration material ” ，but an important component of system efficiency improvement. In recent years, some leading filter cloth manufacturers (such as Xiamen Citius (Xiamen Citius) ) have launched customized product lines for the fiberboard industry, including:
- Low-energy consumption, high-throughput filter cloth ：Reduce the load on vacuum units and extend the operating cycle
- Hydrophobic anti-clogging surface technology ：Improve slurry separation efficiency and reduce cleaning frequency
- Environmentally friendly materials ：Use recyclable, low-emission PET recycled fiber filter cloth
- Structural reinforcement design ：The filter cloth is laminated with multiple layers of support to improve mechanical stability and service life
In addition, some companies have also integrated filter cloth into intelligent operation and maintenance systems to achieve digital management such as filter cloth replacement warnings, operation monitoring, and filter cloth life records.
III. Sharing of Practical Cases: Optimization Experience of a Southern Fiberboard Enterprise with an Annual Output of 20 ten thousand m³ of fiberboard
The company's original white water recycling system used ordinary polyester mesh, which had the following problems:
- Low fiber recovery rate, resulting in high raw material loss
- Fast filter cloth wear 2 Requires replacement every month
- High fiber concentration in the filtrate, leading to frequent sedimentation in the slurry settling tank
After switching to custom-made wear-resistant high-porosity filter cloth:
- Improved forming efficiency 15% More uniform fiber distribution
- Filter cloth service life extended to 6 months Annual cost savings exceeding 10 ten thousand yuan
- Significantly improved filtrate cleanliness Enhanced system stability
At the same time, the filter cloth of the filter press was also upgraded from ordinary cloth to high-pressure structure filter cloth, and the moisture content of the filter cake was reduced from the original 25% to 18% resulting in a significant reduction in the cost of transportation and disposal of waste residue at the back end.
IV. Conclusion
The fiberboard industry's requirements for filtration equipment and materials are moving towards higher efficiency, environmental friendliness, and durability. Industrial filter cloth, as a bridge connecting production processes and operational efficiency, plays a key role in separation and protection in various equipment such as wet forming, glue recovery, wastewater treatment, and dust removal and acid removal.
Selecting appropriate filter cloth materials and structures can not only improve filtration efficiency but also significantly reduce operating and maintenance costs and enhance the sustainability of equipment operation. With process upgrades and stricter environmental standards, industrial filter cloth will play an increasingly irreplaceable role in the fiberboard industry.
