Corrosion Resistant Base Material for Guoshun Group Filter Bag
The corrosion-resistant base material is the first guarantee for the filter bag corrosion resistance of Guoshun Group. The company uses high-performance chemical-resistant fibers such as PTFE (Polytetrafluoroethylene) and PPS (Polyphenylene Sulfide) as the base material of the filter bag. These fibers have good chemical stability and can withstand the corrosion of flue gas, including sulfur oxides, nitrogen oxides, and hydrochloric acid. PTFE and PPS fibers do not undergo oxidation and decomposition like common fibers and can withstand long-term contact with corrosive affected materials. Guoshun Group Filter Bag made of PTFE fiber used in the Flue gas desulfurization project of Shandong Xinfa Xinyuan Aluminum Co., Ltd. has been in operation for more than 5 years without any corrosion, which proves the reliability of the base material.
Anti-Corrosion Coating Technology at Guoshun Group
Guoshun Group adds a unique anti-corrosion coating on the filter bag base material to enhance the corrosion resistance of the filter bag coating. The coating is a type of modified fluoropolymer with high chemical inertness. This coating will create a dense protective film on the filter bag surface which will separate the base material from the chemically aggressive components of flue gas. This film inhibits chemical attacks of corrosive filter bag components. Also, the coating is highly chemically inert, and adhesion and abrasion resistant, therefore it does not flake off due to the flue gas scouring and cleaning activities. In the chemical industry flue gas treatment project with high sulfur content, the anti-corrosion filter bags show excellent corrosion resistance to ensure long term effective performance.
Guoshun Group Filter Bag's Sealed Structural Design
The bag’s sealed structural design effectively avoids corrosive media entering the filter’s interior components. The group optimizes the bag’s stitching design, employing specific sewing threads designed to withstand corrosion and high temperatures. Additionally, they utilize multi-layer stitching to achieve better seam tightness. A sealing ring, made of corrosion-resistant rubber, is integrated at the connection between the filter bag and the dust collector to eradicate any gaps. This design also helps avoid the filter bag internal corrosion caused by the connection and the corrosive flue gases. Local corrosion, caused by corrosive media, is minimized and the corrosion resistance of the filter bag is maximized.
Intelligent Anti-Corrosion Monitoring for Filter Bags at Guoshun Group
At Guoshun Group, we use smart systems that operate dynamically and offer real-time sustained support regarding the corrosion resistance of filter bags. Guoshun Intelligent Operation System has the ability to monitor in real time and set off alarms regarding the composition of corrosive flue gas, temperature, and humidity. Furthermore, the system can outline filter bag operational status through collected data, foresee possible corrosion, and suggest process parameter adjustments for flue gas treatment. Qualified professionals conduct regular site inspections and filter bag performance evaluations, and performing maintenance or replacement of corroded bags. The intelligent early warning system has the ability to monitor and corral corrosion to an extent that has never been achieved before.
Thorough Corrosion Resistance Quality Control on Filter Bags Produced by Guoshun Group
During the manufacturing of filter bags, Guoshun Group implements thorough and rigorous testing and quality control processes for corrosion resistance. From each batch of materials, filter bag bases and coatings, the Guoshun Group performs corrosion resistance testing, including corrosion resistance immersion testing in both acid and base solutions and hot corrosion testing, to determine if the materials and coatings meet the design criteria. Adherence to the production of materials and coatings processes meets the ISO 9001 quality management system standards, with regard to documented professional staff who monitor each step in order to ensure that quality corrosion resistance defects do not occur. Filter bags are provided to customers only if they have passed all corrosion resistance testing. Guoshun Group filter bags undergo thorough corrosion resistance quality control to ensure dependable quality.
Each industry handles a variety of components in their hot flue gas which can be corrosive, so it is necessary for Guoshun Group to tailor make the corrosion resistance solution for filter bags to meet the customer needs. Guoshun Group has a well-versed professional technical team which analyzes, in detail, the composition of the flue gas, the working conditions, and the corrosion resistance, and determines the appropriate base, coating, and design structures to customize the filter bags. For example, in the non-ferrous metal industry, flue gas that contains a high level of chlorine ions, PTFE which is a fiber that has high resistance to chlorine corrosion, is used. Meanwhile, in the chemical industry, flue gases that have high humidity, and high alkalinity, a structure that is double sealed with anti-corrosion coatings, and has a high level of sealing is used. This customized service guarantees the filter bags the highest level of protection against corrosion in a given corrosive environment.
