ASTM-D | Standard Test Methods for Felt (Withdrawn ) | Document Center, Inc.

Digital Thickness Gauge with 9. The filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D 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. The first polymer can have a denier between 0. We Accept Printable Order Form. In one embodiment, an acid resistance tensile test is preformed with a testing machine suitable for ASTM D 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.

ASTM D – Standard Test Methods for Felt

Weights g less foot weight of 18g less spingle and Footer In terms of percentage strength loss, the sample exhibits virtually no loss after the first two d61. In one embodiment, the nonwoven filter media can be supported by a scrim that can be 1. A scrim can be included in the filter media to support the blended fibers. Thanks for your patience.

From these results, we can see that the clean gas concentration can be less than 0. Search Expert Search Quick Search.

This invention is directed to a filter media with improved heat resistance and performance properties, specifically, a filter media with improved cycle times, particulate removal efficiency, heat resistance and chemical resistance. The weight of the filter media can be between 5. Reticulated pore formers for ceramic articles. The denier of these fibers can be astmm 0. The nonwoven filter media of claim 1 wherein said filter media has a weight of between 5.

The 6″x6″x 2″ x x 50 asym laboratory grade certified granite base offers a smooth and extremely hard reference plane for precise and repeatable measurements. A sample of the blended fabric is cut into about a 2 inch by 6 inch piece in the machine direction.

FIELD OF THE INVENTION

The filter media can have a thickness between 0. Using the acid resistance tensile test, the results are shown in FIGS. Most baghouses use long, cylindrical filter bags or tubes made of fabric as asstm filter medium. The invention can also include a nonwoven filter media comprising: What is claimed is: The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers.

The process of placing the sample in the 1N H 2 SO 4 solution then drying and cooling the sample defines one cycle. The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim. 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 After the fifth and sixth cycles, the sample can withstand about 70 pounds of force. These heated particles astn contact the filter bag and damage the bag rendered d4461 filtering functionality ineffective.

The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the inorganic fibers. The nonwoven filter media of claim 16 that is laminated with a PTFE membrane. Ast particulates collect on the bag due to at least one of the following forces:
