A US Navy Seaman uses a needlegun to remove old paint and corrosion aboard USS Kitty Hawk. [1] A needlegun scaler, needle scaler, or needle-gun is a tool used to remove rust, mill scale, and old paint from metal surfaces. [2] The tool is used in metalwork applications as diverse as home repair, automotive repair, and shipboard preservation. [3 ...
The typical bell applicator consists of five major assemblies: the valve module, the bell cup, the turbine, the shaping air shroud, and the electrostatic system.. The valve module is a manifold consisting of passages for paint, solvent, and compressed air, and valves to control the flow of materials for paint delivery, cleaning and purging with solvent or hydropurge, and management of ...
Various examples of swarf, including a block of compressed swarf. Swarf, also known as chips or by other process-specific names (such as turnings, filings, or shavings), are pieces of metal, wood, or plastic that are the debris or waste resulting from machining, woodworking, or similar subtractive (material-removing) manufacturing processes.

A paint thinner is a diluent solvent used to dilute oil-based paints or varnish. [ 1 ] [ 2 ] In this context, to dilute is also known as to 'thin'. Solvents labeled "paint thinner" are usually white or mineral spirits .
The chemical pulping processes can often generate enough energy (steam and electricity) to make the mill energy self-sufficient. This energy is generated from wood leftovers (bark and chips) and from black liquor, which in principle is 50% of the incoming wood (as the yield is less than 50% and a majority of the rest ends up in the black liquor ...
The largest machines used in wood processing, often called "Tub or Horizontal Grinders", may handle a material diameter of 2.4 m (8 ft) or greater, and use carbide tipped flail hammers to pulverize wood rather than cut it, producing a shredded wood rather than chip or chunk. These machines usually have a power of 150–750 kW (200–1,000 hp).
Wood pulp is the primary market for the woodchipping industry in Australia. [citation needed] The practice, known as woodchipping, was to make use of most of the woody material in a tree to produce wood chips. This was then converted into paper, hardwood pulp is mainly used for printing paper and softwood pulp is added for good quality. [3]
