Cultured Marble
Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin, with some newer versions using cement mix. This category includes engineered quartz (SiO2), polymer concrete and engineered marble stone. The application of these products depends on the original stone used. For engineered marbles the most common application is indoor flooring and walls, while the quartz based product is used primarily for kitchen countertops as an alternative to laminate or granite. Related materials include geopolymers and cast stone. Unlike terrazzo, the material is factory made in either blocks or slabs, cut and polished by fabricators, and assembled at the worksite. Engineered stone is also commonly referred to as agglomerate or agglomerated stone, the last term being that recognised by European Standards (EN 14618), although to add to the terminological confusion, this standard also includes mat ...

Solid Surface Material
Solid surface material, also known as solid surface composite, is a man-made material usually composed of a combination of Aluminium hydroxide, alumina trihydrate (ATH), Acrylic resin, acrylic, Epoxy resin, epoxy or polyester resins and pigments. It is most frequently used for seamless countertop installations. A solid surface material was first introduced by DuPont in 1967 under the name of Corian. Since the expiration of their patent other manufacturers have entered the market with their own branded products. These include Krion® by Porcelanosa Grupo, HIMACS by LX Hausys, Hanex Solid Surface by Hyundai L&C, Staron by Lotte Chemical and Velstone. History and characteristics DuPont created and marketed the first solid surface material in 1967, trademarked as Corian. The product was invented by DuPont biochemist Don Slocum that year, and was patented in 1968. Corian consists of a blend of alumina trihydrate, acrylic resin and various pigments. Originally marketed as a counterto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agglomerate
Agglomerate (from the Latin ''agglomerare'' meaning "to form into a ball") is a coarse accumulation of large blocks of volcanic material that contains at least 75% bombs. Volcanic bombs differ from volcanic blocks in that their shape records fluidal surfaces: they may, for example, have ropy, cauliform, scoriaceous, folded, spindle, spatter, ribbon, ragged, or amoeboid shapes. Globular masses of lava may have been shot from the crater at a time when partly molten lava was exposed, and was frequently shattered by sudden outbursts of steam. These bombs were viscous at the moment of ejection and by rotation in the air acquired their shape. They are commonly in diameter, but specimens as large as have been observed. There is less variety in their composition at any one volcanic centre than in the case of the lithic blocks, and their composition indicates the type of magma being erupted. Agglomerates are typically found near volcanic vents and within volcanic conduits, where the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Stone
Artificial stone is a name for various synthetic stone products produced from the 18th century onward. Uses include statuary, architectural details, fencing and rails, building construction, civil engineering work, and industrial applications such as grindstones. History One of the earliest examples of artificial stone was Coade stone (originally called ''Lithodipyra''), a ceramic created by Eleanor Coade (1733–1821), and produced from 1769 to 1833. Later, in 1844, Frederick Ransome created a Patent Siliceous Stone, which comprised sand and powdered flint in an alkaline solution. By heating it in an enclosed high-temperature steam boiler the siliceous particles were bound together and could be moulded or worked into filtering slabs, vases, tombstones, decorative architectural work, emery wheels and grindstones. This was followed by Victoria stone, which comprises three parts finely-crushed Mountsorrel (Leicestershire) granite to one of Portland cement, mechanically mixed an ...

Occupational Safety And Health Administration
The Occupational Safety and Health Administration (OSHA; ) is a regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act (OSH Act), which President Richard Nixon, Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance." The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival. History The Bureau of Labor Standards of the Department of Labor has worked on some work safety issues since its creation in 1934. Economi ...

Silicosis
Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. It is marked by inflammation and scarring in the form of Nodule (medicine), nodular lesions in the upper lobes of the lungs. It is a type of pneumoconiosis. Silicosis, particularly the acute form, is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis. Using workplace controls, silicosis is almost always a preventable disease. Silicosis resulted in at least 43,000 deaths globally in 2013, down from at least 50,000 deaths in 1990. The name ''silicosis'' (from the Latin ''silex'', or flint) was originally used in 1870 by Achille Visconti (1836–1911), prosector in the Ospedale Maggiore of Milan. The recognition of respiratory problems from breathing in dust dates to ancient Greeks and Romans. Georgius Agricola, Agricola, in the mid-16th century, wrote about ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock that was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts, and hence quartzite is a metasandstone. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mohs Scale
The Mohs scale ( ) of mineral hardness is a qualitative ordinal scale, from 1 to 10, characterizing scratch resistance of minerals through the ability of harder material to scratch softer material. The scale was introduced in 1812 by the German geologist and mineralogist Friedrich Mohs, in his book (English: Attempt at an elementary method for the natural-historical determination and recognition of fossils); it is one of several definitions of hardness in materials science, some of which are more quantitative. The method of comparing hardness by observing which minerals can scratch others is of great antiquity, having been mentioned by Theophrastus in his treatise ''On Stones'', , followed by Pliny the Elder in his '' Naturalis Historia'', . The Mohs scale is useful for identification of minerals in the field, but is not an accurate predictor of how well materials endure in an industrial setting. Reference minerals The Mohs scale of mineral hardness is based on the ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trivet
A trivet is an object placed between a serving dish, bowl, pot, or pan and a dining table, usually to protect the table from heat damage. The word ''trivet'' refers to three feet, but the term is sometimes used in British English to refer to trivets with four feet or no feet. ''Trivet'' also refers to a tripod used to elevate pots from the coals of an open fire (the word ''trivet'' itself ultimately comes from Latin ''tripes'' meaning "tripod"). Metal trivets are often tripod-like structures with three legs to support the trivet horizontally to hold the dish or pot above the table surface. These are often included with modern non-electric pressure cookers. A trivet may often contain a receptacle for a candle that can be lit to keep food warm. A three-legged design can reduce wobbling on uneven surfaces. Modern trivets are made from metal, wood, ceramic, fabric, silicone or cork. When roasting any meat in an oven, trivet racks - which typically fit into roasting pans - are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Water Jet Cutter
A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using an extremely high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber. Waterjet cutting is often used during the fabrication of machine parts. It is the preferred method when the materials being cut are sensitive to the high temperatures generated by other methods; examples of such materials include plastic and aluminium. Waterjet cutting is used in various industries, including mining and aerospace, for cutting, shaping, and reamer, reaming. History Waterjet While using high-pressure water for erosion dates bac ...
