Our company is the authorized producer for the “NOMEX” filtration material of the fiber department of Dupont group China. NOMEX® fiber has the characteristics of heat and flame retardant. The continuous working temperature is 204℃ and instantaneous working temperature is 240℃. Its unique structure if β-aromatic ring and the key link between conjugate amine very strong. It can resist the chemical attack. Therefore, NOMEX® will not melt or drop, even explode the high temperature environment for long time. It will only be scorched(LOI: limit oxygen index is 29%). But in general the hot flue gas contains not only water but also mixed with acid gases and other impurities, such as: sulfur oxide, hydrochloric acid, nitric oxide, calcium hydroxide etc. These gases will accelerate the hydrolysis reactions of the filtration bag (NOMEX regain rate of water is 4.5%). Especially when the dust collection room is below the dew point of acid, the hydrolysis effect is more serious. Therefore, we recommend that the temperature of the dust catcher should be controlled at 20℃ above the dew point while using NOMEX® filtration bag. The filtration bag is the best choice for the dust collection for the fields of asphalt-stirring, steel, cement and other high-temperature conditions.
NOMEX is the trade name of the high temperature resistant non-woven needled felt made with the fiber produced by Dupont US, CONEX is that of the product made with the fiber produced by Tejin Japan.
The filtration bag made with the fiber has the advantage if good high temperature resistance and good dimension stability. It also resists to acid and alkaline. The product is widely used in fields of chemical industry, steel and iron, carbon, cement, asphalt-stirring etc. It is the most widely used materials in the field of dust collection at high temperature.
