Binzhou Xintai Alkali Free Glass Fiber Needled Blanket for Automobile Sound Absorption, Insulation, Shock Absorption, and Flame retardancy
Glass fiber needle punched felt is a new type of high-temperature filtration material with reasonable structure and excellent performance. It is made from glass fiber as raw material and needle punched into felt. It has a three-dimensional pore structure, high porosity, low resistance, and a dust removal efficiency that exceeds that of fabric filter materials, reaching 99.9%. The filtration speed is about twice that of fabric filter material. This filter material is suitable for high-temperature flue gas filtration in industries such as carbon black chemical, steel, metallurgy, coal-fired boilers, refractory materials, and cement. Suitable for use in pulse ash cleaning and high-speed reverse blowing bag filters. After long-term testing with high-temperature and corrosive media, it has excellent performance, effectively controlling dust pollution, and recycling valuable fine particle products.
Glass fiber needle felt can be used for sound insulation, absorption, shock absorption, flame retardancy, etc. in the automotive industry, mainly used in the filtration field of industry; High temperature flue gas filtration; Glass fiber needle felt is widely used in various bag filters for flue gas purification and dust recovery in industries such as carbon black, steel, non-ferrous metals, chemical industry, and incineration.
The main uses of fiberglass needle felt are:
1. The characteristics of using fiberglass needle felt in the inner core of a muffler are: high porosity, high sound absorption rate, and low thermal conductivity. In addition, glass fiber itself has characteristics such as high heat resistance, good strength and toughness, and corrosion resistance, making it widely used in the field of automotive and motorcycle silencers in major automobile production countries. Firstly, utilizing its excellent sound absorption performance to achieve noise reduction effects; Secondly, utilizing its high insulation and heat resistance performance, the mixed gas undergoes sufficient chemical reactions in the high-temperature environment of the exhaust pipeline, thereby achieving low emissions of exhaust gas.
2. The surface of the glass fiber needle felt is bonded with aluminum foil, plastic cloth, glass fiber cloth, etc. After processing and cutting into strips, it is used for insulation and protection of cold and hot pipelines as well as underground pipelines; The insulation and sound insulation of the generator set can also be used for the insulation and sound insulation of colored steel tiles, with excellent results.
3. After immersing the fiberglass needle felt into resin and processing it into a plate shape, it can be used as insulation and sound insulation material for building and air conditioning machine liners.
