What are the materials used for filter cotton?
What are the materials used for filter cotton?I. Synthetic fiber filter cotton:The general filtration environment can fully replace the non-woven fabric and glass fiber to cover the coarse, medium, and high-efficiency full range of filtration products, which is an emerging filter material, but also the main direction of progress in future filter materials. It has the advantages of low resistance, lightweight, large capacity, environmental protection, and moderate price compared with other filter materials of the same class. Adopting polyester fiber as the main raw material, abbreviated as PET, polyester fiber is made from polyethylene terephthalate, also known as synthetic fiber or polyester. Polyester has excellent wrinkle resistance, elasticity, and dimensional stability, good electrical insulation properties, is resistant to sun finish, friction resistance, no mold, and no moth, has good resistance to chemical reagents, and can resist weak acids and weak alkalis. The industry is called: chemical fibers, chemical fibers are divided into large chemical fibers and small chemical fibers, and large chemical fibers are polyester fibers produced with high-quality PET chips. Small chemical fiber refers to some small and medium-sized manufacturers with poor-quality recycled PET chips produced from recycled material fiber. II, non-woven filter cotton: The scientific name polyester fiber, commonly known as non-woven fabric, non-woven fabric has a wide range of use, and technical maturity, is the primary, primary air filter in the effective plate, bag filter typical filter material. The production process is made of melt-blown, needle-punched, hydroentangled, spun-bonded, and other processes, and has a stable quality compared to other filter materials of the same level, what are they? It has the advantages of stable quality, greater dust-holding capacity, high moisture resistance, long service life, and economic durability. Nonwoven is also a very early application of filtration materials, technical progress is mature, and production costs are low, in recent years due to continuous technology, the emergence of composite nonwoven greatly improve the cheap low-grade image of nonwoven, inefficiency can already reach sub-efficient. At the same time, composite nonwoven filter media can also be used for filtration in places with relatively high requirements for air cleanliness. III. Glass fiber filter cotton: Glass fiber filter cotton is mainly made of various glass fibers of different thicknesses and lengths by special processing techniques. Glass fiber with its stable performance, high-temperature resistance, high efficiency, large capacity, long service life, and other characteristics. And in some special environments also only glass fiber can be competent. It is widely used in general ventilation systems for primary filters, high-temperature resistant filters, and high-efficiency filters, in places and environments with high requirements for air filtration. |
