Particulate matte

Emission of certain toxic chemicals and particulate mattes have been regulated under this act. These pollutants include sulfur dioxide, carbon monoxide, nitrogen oxides, hydrocarbons, ozone, photochemical oxidants, and particulate materials. There are two categories of regulations for toxic substances in the air (1) the ambient air regulations. 

Copper conversion Copper matte, scrap copper, siliceous flux Sulfur dioxide, particulate matter containing arsenic, antimony, cadmium, lead, mercury, and zinc Acid plant blowdown slurry/sludge, slag containing iron sulfides, silica... 

Finally we address the emulsion layers that contain light-sensitive silver halide. Some of these other layers, as discussed above, contain particulates such as matte beads in overcoats, nanoparticulate semiconductors in antistat layers, copolymeric latexes in subbing layers, etc. Such layers are intrinsically composite multiphase layers, and this is also the case for the light-sensitive emulsion layers. In addition to microcrystals or nanocrystals of silver halide, present to capture light and to form developable... 

A wide variety of particulate substances have been added to epoxies, usually as fillers, but for other purposes as well. Added fillers are often trsed to increase epoxy viscosity, but antimony trioxide mixed with cured, ehlorinated polyester (12) imparts flame resistance, molybdenum disulfide or graphite give a sirrtace-ltrbricating effect, and polypropylene addition produces a matte surface which has improved scratch resistance. Organic or glass microballoons are sometimes added to reduce...
