A Study of SDT in an Ammonium Nitrate (NH 4 NO 3) Based Granular Explosive. NASA Astrophysics Data System (ADS) Burns, Malcolm; Taylor, Peter. 2007-06-01. In order to study the SDT process in a granular non ideal explosive (NIE) an experimental technique has been developed that allows the granular explosive to be shock initiated at a well controlled ``tap density''''.
A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Mode of action Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%.

2020-8-18 · Description. PM 10 is particulate matter 10 micrometers or less in diameter, PM 2.5 is particulate matter 2.5 micrometers or less in diameter. PM 2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any appliion.

2013-10-10 · ammonium ions which, together with elemental and organic carbon made up 70–80% of the total PM2.5 mass. In contrast, these components made up only about 10–20% of the coarse fraction between 2.5 and 10 µm. The coarse fraction was dominated by aluminium, silicon, sulfur, potassium calcium and iron, which made up 40–50% of its mass.

A pre- filter is desirable to lengthen the life of the HEPA filter. Fil- ters with a large flow capacity should be chosen with the eye on low operation cost and a continuous use of 8-12 months. Auto-winding type of electrostatic self-washing type of filter is preferred for long period use.

Diesel particulate filter - Wikipedia
2020-8-15 · Unlike a alytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter; however, the DPF does not retain small particles and maintenance-free DPFs break larger particles into smaller ones.  There are a variety of diesel particulate filter technologies on the market.

2020-3-21 · In contrast, filters for light-duty diesel engines typically use substrates made of materials of higher thermal durability such as silicon carbide. Another notable difference in the design of diesel and gasoline filter substrates is their thermal mass. Diesel substrates have high thermal mass to protect the DPF against thermal damage (melting
