Introduction of filter bag model and material.At present, there are two kinds of filter bags in the market, which are widely used: industrial filter bag (eponymous dust removal filter bag) and liquid filter bag (eponymous fluid filter bag).The most commonly used materials for liquid filter bags are polypropylene fiber needle-punched felt, polyester fiber needle-punched felt and nylon monofilament.
Industrial filter bags mainly have excellent filtering effect on dust, powder, smoke and tobacco. The main filtering objects include boiler room, waste incineration plant, metallurgical plant, chemical plant, etc. Of course, industrial filter bags of different materials are selected according to the actual working environment.P84 needle-punched felt filter bag can withstand high temperature up to 280℃, and can work normally under high temperature environment of 260℃. It has stable performance, strong chemical compatibility, acid and alkali resistance, bending resistance and other characteristics, and has excellent effect on fine dust filtering.Difluoromees filter bag can work normally at the temperature of 220℃, the highest temperature can be up to 280℃, with high temperature resistance, acid and alkali resistance, corrosion resistance, wear resistance and other characteristics, and has excellent filtration efficiency, the diameter of particle impurities greater than 0.1 micron filtration efficiency can be more than 99%, and not easy to jam, often used in waste incineration plant, chemical plant, etc.Metas filter bag can withstand high temperature up to 300℃, can work normally in the environment of 200℃, acid and alkali resistance is relatively general, its surface after special technology treatment, with easy to remove ash, waterproof, anti-static and other characteristics, often used in steel, metallurgy, plastic and other industries;Glass fiber needle-felt filter bag can instantly withstand high temperature up to 300℃, and can work normally at 280℃. It is an efficient high temperature filter bag with stable structure, high strength, good permeability and affordable price. It is a very cost-effective filter bag, often used in power generation, chemical industry and other industries.
Liquid filter bag mainly has excellent filtering effect on paint, graphite, electrophoretic primer, pure water and other liquids. The main filtering objects include pharmaceutical, food, beverage, paint, automobile manufacturing and other industries. Of course, different liquid filter bags are selected according to the actual working environment.Polypropylene fiber needle-punched felt filter bag can work normally at the highest temperature of 90℃. It has strong chemical compatibility, strong acid and alkali resistance, and stable wear-resisting mechanism. It is often used in chemical and pharmaceutical industries.Polyester needle-punched felt filter bag can work normally at 135℃, with normal acid-alkali resistance and high filtration efficiency at room temperature. It is often used in food, beverage, pure water filtration and other industries.Nylon monofilaments filter bag can also work under the high temperature of 135℃, its acid and alkali resistance is more general, but its structure is stable, high filtration accuracy, often used for automotive manufacturing, paint, graphite, electrophoresis primer and other industries filtration.
