Magic Eraser
A " Mr. Clean Magic Eraser" brand sponge, made from melamine foam Melamine foam is a foam-like material consisting of a melamine-formaldehyde condensate. It is the active component of a number of abrasive cleaner sponges, notably the Magic Eraser. It is also used as thermal insulation and as a soundproofing material. Properties The open-cell foam is microporous and its polymeric substance is very hard, so that when used for cleaning it works like extremely fine sandpaper, getting into tiny grooves and pits in the object being cleaned. On a larger scale, the material feels soft because the reticulated foam bubbles interconnect. Its structure is a 3D network of very hard strands, when compared to the array of separate bubbles in a material such as styrofoam. Being microporous, it also effectively absorbs sound waves. Being open-cell, it entrains countless air bubbles, giving it low thermal conductivity and thereby making it an effective insulator. Cleaning In the ear ...

Hubcap
A hubcap or hub cap is a decorative disk on an automobile wheel that covers at minimum the central portion of the wheel, called the hub. An automobile hubcap is used to cover the wheel hub and the wheel fasteners to reduce the accumulation of dirt and moisture. It also has the function of decorating the car. A hubcap is technically a small cover over the center of the wheel, while a wheel cover is a decorative metal or plastic disk that snaps or bolts onto and covers the entire face of the wheel. Cars with stamped steel wheels often use a full-wheel cover that conceals the entire wheel. Cars with alloy wheels or styled steel wheels generally use smaller hubcaps, sometimes called center caps. Alternatively, a wheel cover or spare tire cover can be an accessory that covers an external rear-mounted spare tire found on some automobiles. History Hubcaps were first used on the Newton Reaction Carriage in 1680. The first hubcaps were more commonly known as dust or grease caps. ...

Snopes
''Snopes'' (), formerly known as the ''Urban Legends Reference Pages'', is a fact-checking website. It has been described as a "well-regarded reference for sorting out myths and rumors" on the Internet. The site has also been seen as a source for both validating and debunking urban legends and similar stories in American popular culture. History 1990s In 1994, David and Barbara Mikkelson created an urban folklore web site that would become ''Snopes.com''. ''Snopes'' was an early online encyclopedia focused on urban legends, which mainly presented search results of user discussions based at first on their contributions to the Usenet newsgroup alt.folklore.urban (AFU) where they'd been active. The site grew to encompass a wide range of subjects and became a resource to which Internet users began submitting pictures and stories of questionable veracity. According to the Mikkelsons, ''Snopes'' predated the search engine concept of fact-checking via search results. David Mik ...

Melamine Resin
Melamine resin or melamine formaldehyde (also shortened to melamine) is a resin with melamine rings terminated with multiple hydroxyl groups derived from formaldehyde. This thermosetting plastic material is made from melamine and formaldehyde. In its butylated form, it is dissolved in n-Butanol, ''n''-butanol and xylene. It is then used to cross-link with alkyd, epoxy, Acrylic resin, acrylic, and polyester resins, used in surface coatings. There are many types, varying from very slow to very fast curing. Curing Melamine-formaldehyde can be curing (chemistry), cured by heating, which induces dehydration and crosslinking. The crosslinking can be carried out to a limited degree to give resins. Either the melamine-formaldehyde resins or melamine-formaldehyde "monomer" can be cured by treatment with any of several polyols. Applications Construction material The principal use of melamine resin is as the main constituent of high-pressure laminates, such as Formica (plastic), For ...

Shinkansen
The , colloquially known in English as the bullet train, is a network of high-speed railway lines in Japan. It was initially built to connect distant Japanese regions with Tokyo, the capital, to aid economic growth and development. Beyond long-distance travel, some sections around the List of metropolitan areas in Japan, largest metropolitan areas are used as a commuter rail network. It is owned by the Japan Railway Construction, Transport and Technology Agency and operated by five Japan Railways Group companies. Starting with the Tokaido Shinkansen () in 1964, the network has expanded to consist of of lines with maximum speeds of , of Mini-shinkansen lines with a maximum speed of , and of spur lines with Shinkansen services. The network links most major cities on the islands of Honshu and Kyushu, and connects to Hakodate on the northern island of Hokkaido.

Sound Stage
A sound stage (also written soundstage) is a large, soundproof structure, building or room with large doors and high ceilings, used for the production of theatrical film-making and television productions, usually located on a secured movie or television studio property. Compared to a silent stage, a sound stage is sound-proofed so that sound can be recorded along with the images. The recordings are known as ''production sound''. Because most sound in movies, other than dialogue, is added in post-production, this generally means that the main difference between the two is that sound stages are used for dialogue scenes, but silent stages are not. An alternative to production sound is to record additional dialogue during post-production (known as dubbing). Early history Structures of this type were in use in the motion picture industry before the advent of sound recording. Early stages for silent movies were built, either as a three-wall open-roof set, or with large skylights, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ductwork
Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air. The needed airflows include, for example, ''supply air'', ''return air'', and ''exhaust air''. Ducts commonly also deliver '' ventilation air'' as part of the supply air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort. A duct system is also called ''ductwork''. Planning (laying out), sizing, optimizing, detailing, and finding the pressure losses through a duct system is called ''duct design''. Materials Ducts can be made out of the following materials: They are Galvanized steel Galvanized mild steel is the standard and most common material used in fabricating ductwork because the zinc coating of this metal prevents rusting and avoids cost of painting. For insulation purposes, metal ducts are typically lined with faced fiberglass blankets (duct liner) or wrapped externally with fiberglass blankets (duct wrap) ...

Thermal Insulation
Thermal insulation is the reduction of heat transfer (i.e., the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials. Heat flow is an inevitable consequence of contact between objects of different temperature. Thermal insulation provides a region of insulation in which thermal conduction is reduced, creating a thermal break or thermal barrier, or thermal radiation is reflected rather than absorbed by the lower-temperature body. The insulating capability of a material is measured as the inverse of thermal conductivity, thermal conductivity (k). Low thermal conductivity is equivalent to high insulating capability (R-value (insulation), resistance value). In thermal engineering, other important properties of insulating materials are product density, density (ρ) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
