GEODIS' latest development of asphalt station Metas high temperature filter bags

Metas high temperature bag
Note that Metas is the collective name for Nomex produced by DuPont in the United States
and Conex produced by Teijin of Japan. To sew Metas filter bags, you must use special Sewing thread, produced by our factory
Sewing thread, has high strength
and good wear resistance, and the temperature resistance can reach
< ℃ ℃
and above.
Under normal flue gas temperature conditions, only high-temperature cloth bags are needed
. . Can withstand temperatures
. . < ℃ ℃
In these cases, polyester, polypropylene, acrylic, Nylon and other chemical fibers are basically competent, but for occasions with relatively high flue gas temperatures, such as chemical industry, carbon black (white carbon black) exhaust gas, ironmaking plant blast furnace gas, cement plant shaft kiln exhaust gas, calcium carbide factory kiln exhaust gas, casting, Steel plant flue gas, asphalt concrete mixing asphalt flue gas, refractory brick kiln flue gas, coking flue gas, etc., firstly, because these dusty flue gas dust is not suitable for collection by electric precipitator due to the limitation of specific resistance, it can only be collected by electric precipitator. Use cloth bags or other methods to collect. Secondly, if the temperature of the dusty flue gas needs to be lowered to
< ℃ ℃
, the investment will be high or it will be restricted by the site. Thirdly, because the dusty flue gas contains The composition of sulfur, dusty flue gas has acid
dew point
. .
. . Dusty flue gas can only be filtered and separated above the acid dew point, that is, at a higher temperature, and other factors , so it is necessary to have a chemical fiber that can withstand higher temperatures to make high-temperature bags
.
