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. At break, after the third and fourth cycle, the sample can withstand 80 Ids of force.
FIELD OF THE INVENTION
Southern Felt Company, Inc. The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. Air cleaner, filter element, and methods. From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force.
In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries.
ASTM-D | Standard Test Methods for Felt (Withdrawn ) | Document Center, Inc.
Particulate in the gas stream are deposited on the filter bag. We Accept Printable Order Form.
A SumoBrain Solutions Company. A non woven filter media comprising: The filter media of astn 11 including a scrim supporting said first polymer fiber and said inorganic fibers. For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available.
In one embodiment, the filter media manufactured from the blended fibers has the physical property of total mass removal of about The nonwoven filter media of claim aastm including a first layer and a second layer of nonwoven filter media supported by a scrim. One significant risk associated with some applications is the risk of embers, heated particles or sparks being present in the hopper.
Lead Time Varies, Please contact us for availability. Tank Pressure 5 Bar 4. In the event that an ember or other hot particle contacts the filter media, a hole can be burned in the filter media severely hampering or completely eliminating its effectiveness. Device used to purify air and keep cleanly the duct of hot air system or central air exchanger. Click for automatic bibliography generation. The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber.
When x461 polyphenylene sulfide fibers and the inorganic fibers are blended and used to manufacture a filter media for a bag filter, the resulting filter can have the physical property of clean gas concentration of less than 0. The particulate then drops to the bottom of the hopper and can be removed from the hopper. Most baghouses use satm, cylindrical filter bags or tubes made of fabric as e461 filter medium.
Therefore, it s461 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. The nonwoven filter media of claim 1 wherein said polyphenylene sulfide fibers have a length of d4611 1 and 4 inches and a diameter of xstm 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 30 microns.
Presser Foot “A” Dim. Optional presser foot diameters and related weights are available and custom sizes can be supplied to accommodate your specifications. The weight of the filter media can be between 5. After the fifth and sixth cycles, the sample can withstand about 70 pounds of force. A spark can also create an undesirably opening in the filter bag. The inorganic fibers are blended with the polyphenylene sulfide asym and supported by a scrim.
The nonwoven filter media of claim 16 that is chemically treated. This weight must be included when calculating test pressure MTG, with Dampener: The first polymer can have a denier of between 0.
ASTM D – 93 Standard Test Methods for Felt (Withdrawn )
The denier of these fibers can be between 0. Click image for more info. The nonwoven filter media of claim 1 wherein said filter media exhibits a residual pressure drop of less than Pa as measured by ASTM-D Custom Sized presser feet and weights mass to fit specific needs or applications are wstm available.
The nonwoven filter media of claim 16 that is laminated with a PTFE membrane. The invention can also include filter media comprising: The nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about The samples are then tested using test method ASTM for strength and d641 with a lbs load. The particulates collect on the bag due to at least one of the following forces: Cable and Software are offered as an option.
DavisTextile Research Journal, Gas having particles enters the baghouse through hopper 10 of FIG. What is claimed is: 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. astn
Using the acid resistance tensile test, the results are shown in FIGS.
