dangers of high calcium to metalic particles manufacture
Calcium - Wikipedia
Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust
What is Sulfated Ash in engine oils | ARTICLES | SOLVER …
These particles can be carried downstream with the exhaust and collect on the diesel particulate filter. These ash particles cannot be removed by filter regeneration because they are not coustible. As the ash particles accumulate, they result in filter blockage that increases back pressure to the engine, increasing fuel consumption and decreasing power.
