The following description is better understood with reference to the incorporated drawings which are part of the description of the invention:. The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and The MTG Digital Contact Thickness Gage accurately measures aetm of textiles, non-wovens, aatm fabrics and many other materials.
The invention can also include a nonwoven filter media comprising: This invention relates to a composition of fibers and filter media made there from that provide for advantageous physical properties, especially for use with bag filters x461 a baghouse.
The nonwoven filter media of claim 1 including a scrim supporting said filter media.
ASTM D MTG Material Thickness Gauge, D, D, ISO
Some of the industries that use bag houses to remove particulates from the air stream include garbage incinerators, coal plants or boilers, furnaces for melting metal and other materials, pharmaceutical production food manufacturing, chemical production and cement plants.
This model is NOT recommended when testing requires specific test pressure. The filter media can have a thickness between 0.
Custom Sized presser feet and weights mass to fit specific needs or applications are also available. The nonwoven filter media of claim 16 including a scrim supporting said first fibers and said inorganic fibers. Click image for more info. The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand lifting lever.

Refer to details below. The nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about A SumoBrain Solutions Company. Click for automatic bibliography generation. The 6″x6″x 2″ x x 50 mm laboratory grade certified granite base offers a smooth and extremely hard reference plane for precise and repeatable measurements. The first polymer wstm have a denier of between 0. With the above test parameter and tested filter d4461, the following results were achieved as shown in Tables 1 and 2: From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force.
The following table illustrates the physical property benefit of the present invention when compared to a polyphenylene sulfide PPS fiber alone. The invention can also include filter media comprising: What is claimed is: No orders will ship and email response will be delayed during this time.
The indicator is fitted on an 8 inch mm tall column to allow the indicator to be raised or lowered to accommodate different size test specimens. We Accept Printable Order Form. Further, there can be chemicals in the air stream that are corrosive or otherwise damaging ashm the filter bag itself.
Lead Time Varies, Please contact us for availability. We are closed until January 2nd. The particulate then drops to the bottom of the hopper and can be removed from the hopper. For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available.
Digital Thickness Gauge with 9. Tank Pressure 5 Bar 4. The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers. The denier of the inorganic fiber can be between 0.
The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim.
FIELD OF THE INVENTION
In one embodiment, the polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 20 microns.
In terms of percentage strength loss, the sample exhibits virtually no loss after the first two cycles. Thanks for your patience. A nonwoven filter media comprising: The nonwoven filter media of claim 16 that is laminated with a PTFE membrane. DavisTextile Research Journal, In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries.
A non woven filter media comprising: The samples are then tested using test method ASTM for strength and elongation with a lbs load. Therefore, it would be advantageous to have a filter bag for a baghouse that was resistant to heated particles and corrosive chemicals while maintaining or improving the performance properties of traditional filter bags.
In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream. The first polymer can have a denier between 0.
