Durability
Durability is the ability of a physical product (business), product to remain functional, without requiring excessive maintenance (technical), maintenance or repair, when faced with the challenges of normal operation over its design life, design lifetime. There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. In economics, goods with a long service life, usable life are referred to as durable goods. Because there is no objective measure of durability for clothing, price has become an important indicator. Requirements for product durability Product durability is predicated by good repairability and Regenerative design, regenerability in conjunction with Maintenance (technical), maintenance. Every durable product must be capable of adapting to technical, technological and design developments. This must be accompanied by a willingness on the part of consumers to forgo having the "very latest" version of a product. ...

Superfest
Superfest, also called CV-Glas or Ceverit until 1980, was a brand of drinking glasses in the GDR. Due to being made of chemically strengthened glass, they were notably strong. The ''Superfest'' glasses were produced between 1980 and 1990 in what was then state-owned ''Sachsenglas Schwepnitz''. The GDR regarded the product as a key potential export and gave it priority for development. However, foreign sales were not secured, as potential buyers regarded the idea of long-life glassware as detrimental to their ability to sell replacements. As state employees in a state owned industry, the inventors did not receive significant financial rewards or royalties, but were honoured for their achievements. Around 120 million glasses were sold by the end of production in 1990, mostly to food and drink establishments within the GDR. Designs included many glass sizes and ice cream cups. The business was wound up by the Treuhand privatisation industry in 1991, and the patent was abandon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chemically Strengthened Glass
Chemically strengthened glass is a type of glass that has increased strength as a result of a post-production chemical process. When broken, it still shatters in long pointed splinters similar to float glass. For this reason, it is not considered a safety glass and must be laminated if safety glass is required. However, chemically strengthened glass is typically six to eight times the strength of float glass. The most common trademark for this kind of glass is Gorilla glass. History Glass is one of the oldest materials created by humans, dating back to about 4,000 years ago, when craftsmen working in Mesopotamia, the land between the Tigris and Euphrates Rivers, discovered the art of mixing sand, soda, and lime to make glass. Throughout the ages, humans have explored early ion exchange in glass to decorate and color glass artefacts with silver or copper powders. It was only around the beginning of the 20th century that the foundations for a possible application of the ion-e ...

Waterproofing
Waterproofing is the process of making an object, person or structure waterproof or water-resistant so that it remains relatively unaffected by water or resists the ingress of water under specified conditions. Such items may be used in wet environments or underwater to specified depths. ''Water-resistant'' and ''waterproof'' often refer to resistance to penetration of water in its liquid state and possibly under pressure, whereas ''Damp proofing, damp proof'' refers to resistance to humidity or dampness. Permeation of water vapour through a material or structure is reported as a moisture vapor transmission rate (MVTR). The hulls of boats and ships were once waterproofed by applying tar or pitch (resin), pitch. Modern items may be waterproofed by applying water-repellent coatings or by sealing seams with gaskets or o-rings. Waterproofing is used in reference to building structures (such as basements, decks, or wet areas), watercraft, canvas, clothing (raincoats or waders (foot ...

Rustproof
Rustproofing is the prevention or delay of rusting of iron and steel objects, or the permanent wikt:protection, protection against corrosion. Typically, the protection is achieved by a process of surface finishing or treatment. Depending on mechanical wear or environmental conditions, the Chemical decomposition, degradation may not be stopped completely, unless the process is periodically repeated. The term is particularly used in the automobile industry. Vehicle rustproofing Factory In the factory, car bodies are protected with special chemical formulations. Typically, phosphate conversion coatings were used. Some firms galvanization, galvanized part or all of their car bodies before the Primer (paint), primer coat of paint was applied. If a car is body-on-frame, then the frame (chassis) must also be rustproofed. In traditional automotive manufacturing of the early- and mid-20th century, paint was the final part of the rustproofing barrier between the body shell and the atmosp ...

Rot-proof
Rot-proof or rot resistant is a condition of wikt:preservation, preservation or wikt:protection, protection, by a process or Surface finishing, treatment of materials used in industrial manufacturing or Production (economics), production to prevent biodegradation and chemical decomposition. Decomposition is a factor in which organic matter breaks down over time. It is commonly caused by fungus, Mold (fungus), mold or mildew. There are natural conditions where the environment is wikt:inhospitable, inhospitable to animals, bacteria and fungus, for example in high altitude and the freezing subzero temperatures of the Arctic and Antarctic, which creates a similar suspension. The proofing of materials may also prevent dry rot and wet rot.

Residual Stress
In materials science and solid mechanics, residual stresses are stresses that remain in a solid material after the original cause of the stresses has been removed. Residual stress may be desirable or undesirable. For example, laser peening imparts deep beneficial compressive residual stresses into metal components such as turbine engine fan blades, and it is used in toughened glass to allow for large, thin, crack- and scratch-resistant glass displays on smartphones. However, unintended residual stress in a designed structure may cause it to fail prematurely. Residual stresses can result from a variety of mechanisms including inelastic (plastic) deformations, temperature gradients (during thermal cycle) or structural changes ( phase transformation). Heat from welding may cause localized expansion, which is taken up during welding by either the molten metal or the placement of parts being welded. When the finished weldment cools, some areas cool and contract more than others ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Radiation Hardening
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare. Most Semiconductor device, semiconductor electronic components are susceptible to radiation damage, and radiation-hardened (rad-hard) components are based on their non-hardened equivalents, with some design and manufacturing variations that reduce the susceptibility to radiation damage. Due to the low demand and the extensive development and testing required to produce a radiation-tolerant design of a microelectronics, microelectronic chip, the technology of radiation-hardened chips tends to lag behind the most recent developments. They also typically cost more than their commercial cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fireproofing
Fireproofing is rendering something (Building, structures, materials, etc.) resistant to fire, or incombustible; or material for use in making anything fire-proof. It is a passive fire protection measure. "Fireproof" or "fireproofing" can be used as a noun, verb or adjective; it may be hyphenated ("fire-proof"). Applying a certification listing, certification listed fireproofing system to certain structures allows them to have a fire-resistance rating. The term "fireproofing" may be used in conjunction with standards, as reflected in common North American construction specifications. An item classed as fireproof is resistant in specified circumstances, and may burn or be rendered inoperable by fire exceeding the intensity or duration that it is designed to withstand.
