Exfoliation
| Глоссарий по архитектуре и конструкциям |
- Peeling, swelling, or scaling of stone or mineral surfaces in thin layers; caused by chemical or physical weathering or by heat. minerals such as vermiculite expand to many times their original size when heat-treated. exh on drawings, abbr. for “exhaust.”
- The loss of layers of tissue such as sunburnt skin
- Отслаивание; шелушение
- The process by which concentric scales, plates, or shells of rock, from less than a centimeter to several meters in thickness, are successively spalled or stripped from the bare surface of a large rock mass. it often results in a rounded rock mass or dome-shaped hill. gg
- Process by which thin, curvilinear scales or shells or rock are
- Exfoliation is the process of removing dead skin cells from your skin. it can be both physical or manual (using a scrub or tool to slough off dead skin cells) and chemical (with acids or enzymes that dissolve dead skin cells).
- A type of corrosion that progresses approximately parallel to the outer surface of the metal, causing layers of the metal to be elevated by the formation of corrosion product.
- Corrosion that progresses approximately parallel to the outer surface of the metal, causing layers of the metal to be elevated by the formation of corrosion product.
- Corrosion that progresses approximately parallel to the outer surface of the metal, causing layers of the metal to be elevated by the formation of corrosion product.1 exitance, radiant: see radiosity.

Расслаивание, русский
Расслоение, русский
- Коррозия, которая распространяется параллельно к поверхности, обычно по границам зерен. образующиеся продукты коррозии способствуют отделению слоев металла от основного материала, вызывая расслоение. наиболее часто имеет место в деформируемых алюминиевых сплавах.
- Удлинение и выравнивание внутренних границ, вторичных фаз и включений в определенных направлениях, соответствующих направлению потока металла во время деформации.
- (1) тип разрыва или неоднородности с разделением или ослаблением, обычно направленным параллельно рабочей поверхности металла. может быть результатом усадки, швов, окалины, включений или сегрегации, вытянутых и направленно расположенных в процессе работы. расслоения могут также встречаться в прессовках порошковой металлургии. (2) в электротехнических изделиях типа двигателей — пустоты в пакете электрических пластин для статора или ротора, которые сложены вместе с несколькими другими идентичными пластинами.
- Дефект поверхности в виде трещин на кромках и торцах листов и других видов проката, образовавшихся при наличии в металле усадочных дефектов, внутренних разрывов, повышенной загрязненности неметаллическими включениями и при пережоге [11].

Weathering, английский
- The mechanical or chemical disintegration and discolouration of the surface of wood caused by exposure to light, the action of dust and sand carried by winds, and the alternate shrinking and swelling of the surface fibres with the variation in moisture co
- The mechanical or chemical disintegration and discoloration of the surface of wood caused by exposure to light, the action of dust and sand carried by winds, and the alternate shrinking and swelling of the surface fibers with the continual variation in moisture content brought by changes in the weather
- Способность сопротивляться выветриванию [воздействию погодных факторов], атмосферостойкость ~ of structure to perform satisfactory способность сооружения выполнять своё функциональное назначение, соответствие сооружения требованиям нормальной эксплуатации
- All physical disintegration, chemical decomposition, and biologically induced changes in rocks or other deposits at or near the earth`s surface by atmospheric or biologic agents or circulating surface waters with essentially no transport of the altered material. these changes result in disintegration and decomposition of the material. compare - regolith, residuum, saprolite. hp
- Refers to the various processes of physical disintegration and chemical
- The breakdown of large rock masses into smaller pieces by physical and chemical climatological processes.
Vermiculite, английский
- A mineral used as bulk insulation and also as aggregate in insulating and acoustical plaster and in insulating concrete floors.
- A natural mica expanded by heat (i.e., exfoliated) to form lightweight thermal insulating material, used in the expanded state alone as loose-fill or as aggregate with other materials.
- Вермикулит
Отслаивание, русский
Отсоединение одного слоя покрытия от другого или от основного металла из-за слабого сцепления (адгезии).
Concentric, английский
- Концентрический
- Curved lines or surfaces having a common center of curvature.
- Having a common center.
Centimeter, английский
- Сантиметр
- In the metric system, a measure of length equal to a hundredth part of a meter, or 0.3937+ in.; abbreviated cm; an inch equals 2.54 cm. central air-conditioning system an airconditioning system in which the air is treated by equipment at one or more central locations outside the spaces served, and conveyed to and from these spaces by means of fans and pumps through ducts and pipes. central air-handling unit an air-handling unit in which treated air is distributed to a number of spaces by means of ductwork.
Successively, английский
Curvilinear, английский
Криволинейный

Mica pellets, английский
Pellets of exfoliated vermiculite.
Periform, английский
Pear-shaped; said of a roof in the form of a pear (as some baptisteries and eastern churches) or said of a molding having a pear shape.
