Special high temperature dust removal bag for foundry——metas dust removal bag

High-temperature Metas dust bag is particularly suitable for dust removal in foundries. In the foundry profession, Metas dust bag is known as professional dust bag. The maximum temperature resistance of Metas dust bag is above 200 degrees Celsius, which is second to none in the field of high temperature and dust removal.

The high temperature resistant Metas dust bag for foundries has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, folding resistance, etc., through different appearance chemical treatment and post-cleaning technology, it also has easy cleaning, water and oil resistance , Anti-static and other functions, and have suitable 200 ° C-300 ° C series products. In addition to the dust removal bag, in addition to METAS, P-84 and Leiden filter materials have also been widely used.The production and application technology of glass fiber needle felts are now sophisticated and the types have increased. Water, flame retardant, anti-hydrolysis, anti-static treatment, etc., make the filter material can be used to a variety of complex environments and better function.

The high temperature resistant Metas dust bag for foundries has the characteristics of high temperature resistance, high strength, resistance to acid and alkali corrosion, abrasion resistance, folding resistance, etc., through different appearance chemical treatment and post-cleaning technology, it also has easy cleaning, water and oil resistance. , Anti-static and other functions, dust-containing flue gas can only be separated when the temperature is higher than the acid dew point. Under normal flue gas temperature conditions, the bag only needs to be able to withstand temperatures below 150 ° C. In these cases, polyester, polypropylene, acrylic, nylon and other chemical fibers can basically serve.

For those occasions where the temperature of the flue gas is relatively high, for example: chemical industry, carbon black (white carbon black) exhaust gas, iron blast furnace gas, cement plant vertical kiln exhaust, calcium carbide kiln exhaust, casting, steel mill flue gas, asphalt Concrete is mixed with asphalt flue gas, refractory brick kiln flue gas, coking flue gas, etc. First, because these dust-containing flue gas dusts are not suitable for collection by electric dust collectors due to the specific resistance limit, only Metas high temperature needles can be used. It is collected by felt cloth dust bag or other methods; secondly, if the temperature of the dusty flue gas needs to be lowered below 150 ℃, the investment is high or restricted by the site; thirdly, because the dusty flue gas contains sulfur, Dust-containing flue gas has an acid "dew point". Dust-containing flue gas can only be filtered and separated at a temperature above the acid dew point, that is, in a high temperature state. Therefore, a Metas high temperature needle felt felt bag can be used. Higher temperature chemical fibers are used to make filter media. Mitas dust bags for foundries are particularly suitable for these conditions.

The characteristics of the special high temperature Metas dust-removing cloth bag for foundry are as follows:

1. Large dust holding capacity, it can retain a certain permanent dust holding capacity after cleaning, in order to maintain high filtration efficiency;

2. Good air permeability and small pressure loss under uniform dust holding condition;

3. Good resistance to wrinkle, abrasion, temperature, corrosion and mechanical strength;

4. Little hygroscopicity, easy to clean dust;

5. Long life and low cost.

Our company specializes in the production of dust filter bag, room temperature dust bag, high temperature dust filter bag, special dust removal in foundry

Bags, special high-temperature bags for steel plants, special dust-removing bags for chemical plants, anti-static dust-removing bags, water- and oil-repellent needle-punched felt dust-removing bags, flumes dust-removing bags, PPS dust-removing bags, PTFE-coated dust-removing bags, etc. To confirm economical equipment, to meet customer needs, welcome to visit the factory at any time.

Metas needle felt felt bag cloth for foundry is a kind of aromatic polyamide fiber. In addition to the spinnability and abrasion resistance of polyester fiber, the biggest feature of Metas dust bag is its outstanding heat resistance. And flame retardant, non-melting. Fiber oxygen index can be 29%, which is unnatural. At temperatures above 400 ° C, the fibers are slowly carbonized. In addition, Mitas dust filter fiber has outstanding dimensional stability. Compared with glass fiber, its abrasion resistance and folding resistance are unmatched by glass fiber. Therefore, it has high temperature resistance and long service life. It is the first choice filter material for bag dust collectors in high-temperature filtration applications.
