Coordinating Committee

The barrel of the gun was is made of birch intercepted iron hoops. Check out Zendesk for additional information. During the Great Patriotic War on the aircraft manufacturing plants did not have enough metal on the tanks for gasoline, and they started making out bbakelizirovannoy plywood. Wooden tank covered with rubber and installed on an aircraft. When in the early sixties of the xx century, the decision of cocom – Coordinating Committee on Export of strategic goods to the socialist countries (Coordinating Committee of East-West Trade Policy) has been banned exports to the Soviet Union, one of the specific species of wood (grown in Latin America), then our "masters" on the basis of birch was a new material – turned the embargo in an empty sound. This material was used for manufacture of propeller shaft sleeves of high-speed missile boats. During the planned economy, in Leningrad (and not only) produces tubes of birch plywood for pumping oil and gas for ventilation in mines. On such tubes even pumped pulp (fuzzy land) from the city zemsnaryadov.V Kadu (Vologda region) has been established to produce production of birch plywood barrelware. Kaduyskie plywood drums are widely used for packaging food products intended for the Far North, for example: powdered eggs, powdered milk, dried vegetables, etc.

Now oao severtara (formerly Kaduysky factory-pressed plywood drums) is the only enterprise in Russia and the cis for the production of plywood stamped barrels. The appearance of fiberboard In 1858 American Lyman was obtained the first patent for the production of fiberboard. A few years later, in 1864, another scientist named Munch came to think that the paper – this is essentially a very thin fiberboard. He developed equipment for the production of plates without binder by hot pressing. Improved way of producing fibreboard American Mason in 1924, quite by accident. The scientist had gone, first unplug the steam valve for hot-pressing, but due to faulty valve steam continued to flow into the press. When he returned, Mason found in the installation plate is very high density.

The invention Particleboard Particleboard As for the history, the use of first proposed Ernst Hubbard in 1887. He tried to make plates from sawdust and casein glue. German Beckman in 1918 polished slab veneer. And in 1926 another German scientist Freudenberg first calculated the amount of binder (3-10%). Seven years later, American Anthony began to be used as a binder phenolic or urea resin. mdf – Forgotten Ancient Technology And yet, of course, we must mention about that, as appeared in the light of the first mdf. In the form in which we know them today, they were made in 1965 in the usa. mdf – a Medium Density Fiberboard, which translates as Plate medium density. Ancient technology timber that existed during the time of the Aztecs and Mayas, was revived after centuries of neglect only in the late 18 th century in Britain. In the early 19 th century in the U.S. had the first factory for manufacturing fiber board of the porous type. To date, plywood is still cheap and popular material. Among the modern varieties and bakelite plywood, and laminated plywood decorative plywood and air, and water-resistant plywood, wbp, and many others. Plywood demand in virtually all industries. It is used in engineering, construction, furniture manufacture, for the manufacture of musical instruments, toys, for decorative trim and other areas.
