Aramid is known as “Polyphthaloyldiamine”, English is Aramid fiber (Tevarin Aramid’s trade name is Twaron, DuPont’s trade name is Kevlar), and it is a new type of high-tech synthetic fiber with ultra-high High strength, high modulus and high temperature resistance, acid and alkali resistance, light weight and other excellent performance, its strength is about 5 to 6 1/5 of the steel wire. It has good insulation and anti-aging properties, has a long life cycle times, modulus is 2 to 3 times that of steel wire or glass fiber, toughness is 2 times that of steel wire, and the weight is only steel wire. The discovery of Kevlar is considered to be a very important historical process in the material world.
Aramid dust filter bag features:
Excellent temperature resistance: It can be operated at a temperature of 204°C (instantaneous temperature 240°C).
Scale stability: Only a thermal contraction rate of less than 1% at a temperature of 204°C provides excellent high temperature stability.
Chemical resistance: Low concentrations of acids and bases and most hydrocarbons will not affect it. Even a small amount of fluoride will not significantly corrode.
Fire resistance: It begins to differentiate and carbonize at 400°C, with a limiting oxygen index (LOI) of 30. It does not ignite or burn.
Aramid dust filter bags have been proven to be used throughout the high temperature filtration industry. They are used throughout asphalt, lime, steel, non-ferrous metals, lime, dust, metallurgy, drying, crushed stone, plaster, plastic, carbon black, Coke and other high-temperature production industries.
At present, aramid dust filter bags can be divided into three types: domestic aramid dust filter bags, DuPont aramid dust filter bags, Teijin aramid dust filter bags.
Domestic Kevlar dust filter bag
Aramid fibers are mainly divided into two types, para-aramid fibers (PPTA) and meta-aramid fibers (PMIA). Okay environmental Kevlar dust filter bag, raw materials selected domestic excellent products. Good quality, efficient filtration.
