Pre-Oxidized Needle Punched Filter Felt

In the field of dust removal and flue gas purification, the temperature resistance of the traditional filter material is no more than 300℃. Under the working condition higher than 300℃, the traditional filter material can not be used because of shrinkage under high temperature. Polypropylene fiber is an intermediate product of carbon fiber, which is partially cyclized black fiber formed by air oxidation at a certain temperature. Its density is about 1.40g/cm3, strength is 1.4cn/dtex, elongation is 23%, modulus is 5GPa, limiting oxygen index is 35 - 60, decomposition temperature is ≥640, moisture remain is 9%, temperature resistance is outstanding, high temperature resistance is up to 300℃, and is fire resistance and non combustion. It is acid resistant, alkali resistant, washing resistant, non-toxic, less smoke. DwHB specializes in the R&D and production of dust removal filter bags. According to the high temperature resistance of pre-oxidized fiber, DwHB select pre-oxidized fiber with glass fiber and basalt base cloth and the temperature resistance effect can reach 350-400℃, meeting the high temperature resistance requirements under special working conditions.

Why Choose Pre-Oxidized Needle Punched Filter Felt for High-Temperature Flue Gas Purification?

Pre-Oxidized Needle Punched Filter Felt is crafted from polypropylene fiber, an intermediate product of carbon fiber, which undergoes a unique pre-oxidation process. This process involves exposing the fiber to air oxidation at a specific temperature, resulting in a partially cyclized black fiber with exceptional properties. The density, strength, elongation, and modulus of this fiber make it ideal for high-temperature applications, withstanding temperatures up to 300℃ and even higher when combined with other materials.
One of the primary advantages of Pre-Oxidized Needle Punched Filter Felt is its outstanding temperature resistance. Traditional filter materials often shrink or degrade under high-temperature conditions, limiting their use in applications where temperatures exceed 300℃. However, Pre-Oxidized Needle Punched Filter Felt maintains its structural integrity and performance, even in extreme heat. This makes it the perfect choice for industries such as cement, steel, power generation, and chemicals, where flue gas temperatures can reach dangerous levels.
In addition to its temperature resistance, Pre-Oxidized Needle Punched Filter Felt is also known for its durability and long service life. The needle punching process creates a dense and uniform fiber structure, enhancing the material's resistance to wear and tear. This means that the filter bags made from this material can withstand the rigors of continuous operation, reducing the frequency of replacements and lowering maintenance costs.
Jiangsu Dongwang Environmental Protection Technology Group Co., Ltd. takes pride in its ability to customize Pre-Oxidized Needle Punched Filter Felt to meet the specific needs of its clients. The company's R&D team works closely with customers to understand their unique requirements and develop tailored solutions. Whether it's a specific fiber blend, a unique fiber diameter, or a custom filter bag design, Dongwang can deliver.
Moreover, Dongwang's Pre-Oxidized Needle Punched Filter Felt is eco-friendly and safe for industrial use. The material is resistant to acids, alkalis, and washing, making it ideal for a wide range of applications. It is also non-toxic and produces minimal smoke when exposed to heat, ensuring the safety of workers and the environment.
