US company WR Systems has announced that its "outer stack" particulate (PM) measurement technology for Emsys contamination monitoring has been patented.
It is reported that WR Systems' Emsys system is designed to measure emissions of gases and particulates such as NOX, SOX and CO2 and PM. WR Systems said that the United States has strengthened legislation on visible smoke emissions from ships.
Simon Brown, president of HR Systems' international maritime business, said, "Our team spent three years developing this system that combines laser and PM measurement technology. The laser measures the heat and humidity of the gas, so there is no need to use filters, Gas coolers and dryers. Emsys is designed to be installed where exhaust gases are concentrated, enabling one sensor to monitor up to 10 engines and boilers, significantly reducing costs compared to the prior art."
WR Systems has successfully commercialized Emsys. Recent contracts include multiple scrubber monitoring applications, offshore drilling vessels, and new shipbuilding in the Middle East.

Iron Oxide

Iron oxide pigment is chemical compounds composed with formula Fe3O3 . Synthetic iron oxide is the most common colorant in concrete and cement paint. Iron oxide is an important inorganic color pigment, chemical stability, strong color strength, fine dispersion and excellent light resistance, weather resistance.

Major Features:

1)Brilliantly colored powder. Eye-pleasing and durable.
2) Strong coloring power, excellent coverage.
3) Light permanency and weatherability.
4) 6~7 grade resistance to oxidation and light permeability, 4~5 grade resistance to basic materials.

Usage:

1) Used in many types of paints, including anti-rust paint, water-soluble indoor/outdoor paints and oil-based paints.
2) Used for dyeing construction materials, such as mosaic bricks, for concrete bricks, pavement, colorful tiles, roofing tiles and man-made marble. Colors for ceramic body.
3) Used in paper industry, esp. rice paper.
4) Used for surface coloration of plastic epoxy floor, color for pitch.
5) Used as a more fade-resistant dye for plastics.
6) Used as pigment for cosmetic.
7) Used as coloring Sugar-coat for medicine tablets.
