How and where in Russia they make the best plywood in the world. SPHERICAL – Russia today Posting in CHAT: Russia Who would have thought that the familiar plywood is actually a unique, super-strong material, and Russia makes it better than anyone else. Let's find out how this happens and where the best plywood in the world is produced. Valuable raw materials The best plywood is birch, this type is produced only in Russia. Birch is a very valuable species; it is protected and protected from drying out in the sun. For comparison, birch does not grow in the USA, and plywood there is made from softer pine. “The majority of Russian plywood enterprises are located in forest regions with developed infrastructure - the North-Western, Central districts, the Urals and Siberia. During the Great Patriotic War, industry supplied plywood for the needs of the front and rear. Today Russia exports more than 50% of its plywood production to the USA, Canada and the European Union,” writes the FB.ru website. The city of Kirov is one of the centers of the timber industry. Starting early in the morning at the Vyatka plywood mill, birch enters the plant in the form of logs cut into equal parts to create this unique Russian product. They are used to make something like bundles, which are secured with massive metal chains. hot water to steam it. The water appears brown due to the resin that the birch tree produces. It protects the wood from rotting. After some time, the blackened logs are removed to equalize the temperature and allow the heat to distribute deeper into the room. magazines. The wood softens and can now be cleaned by removing the bark and layers of wood from the tree in a spiral pattern. These layers are called milk. The thinnest milk is produced in Russia. The milk is then cut into leaves and dried. A special device finds and cuts out areas with traces of bark or knots and places the pieces in their place. Smart machines glue high-quality linen fabrics at the seams. Making plywood Laminate is made from glued layers of veneer. One sheet of plywood has an odd number of layers. Even layers are glued together with special glue. The layers of milk are laid with fibers perpendicular to each other, which gives the plywood additional strength. Next, cold and hot pressing are performed. The resulting plywood cannot be broken with a blow - it bends under the blow and regains its strength. Plywood, familiar to all of us since childhood, turns out to be a unique, super-strong material. There is no waste during production - everything defective is sent to the production of fiberboard (fibreboard) or fuel briquettes, as well as to thermal power plants. “Despite the apparent complexity of plywood production technology, today it is one of the most profitable types of business in woodworking. Having even a minimal fleet of machinery and equipment, you can build a production facility capable of producing competitive products and generating stable profits,” writes the website lesoteka.com. But this is not all the processes; the products at the Vyatka plywood mill are the cheapest in the industry. Plywood can also be used to create a more durable laminate, or delta wood. Sliding bearings and silent gears are made from such wood. It can even replace bronze. The material resists any impact, does not crack or stretch. The secret of strength is in the bakelite resin with which all layers are impregnated - it can reach hundreds, which even wood can do. be used underwater. In the Soviet Union, lightweight and durable wood was used to make the fuselage and wings of military aircraft, such as the first all-wood Soviet fighter aircraft, nicknamed "Royal". “The use of one or another production technology makes it possible to obtain a material with specified technical parameters. The production of material for formwork or temporary structures is possible from any raw material. But for shipbuilding or the manufacture of light aircraft hulls, bakelite plywood is suitable. We need one that is not inferior to aluminum in its physical and mechanical properties. For this, only high-quality linden or birch is used, with a minimum number of knots. The process of gluing and drying leaves is carried out under strict temperature control. and humidity,” writes the website lesoteka.com. SPHERE https://dzen.ru Source link Source link

“Tomahawks” against plywood missiles. The Houthis have demonstrated mock-ups of cruise missiles worth $300 million. Green Country Diaries Posting in CHAT: Russia Since the appearance of the first footage of objective observation of attacks by the American-British coalition on the Yemeni Ansar Allah movement, a strange feeling has arisen that attacks often occur on some incomprehensible or deliberately exposed objects. For example, footage of RAF Eurofighter Typhoons launching guided bombs clearly looked like they were filming staged props on a film set. The charred remains of old rusty trucks, something vaguely reminiscent of radar and chaotically scattered remains of missiles that for some reason did not explode. All this led to a false position, which we have seen a lot over the past year in chronicles closer to us. However, the British happily reported the destruction of the UAV positions and literally a day later they managed to achieve the arrival of a small drone on a merchant ship under a foreign flag, but under their British jurisdiction. This did not cause any particular damage to the giant cargo ship, but it had to change its route and go for short-term repairs. The Americans also reported the day before about the use of the 100th Tomahawk ship launch system and new exploits of their aviation in destroying the missile potential of Houthi fighters. Yesterday another American tanker Chem Ranger was hit. Photo Al Riyadh. In response to the cheerful American reports, the means of the Yemeni Ansar Allah movement showed that they, too, were able to report on the fighting and which “missile positions” the coalition destroyed as part of Operation Welfare Guardian. Plywood rockets made by local schoolchildren, several decoys emitting powerful radio signals, and a decent amount of real rockets hidden in what appears to be a cave. These photos soon went viral and caused quite a heated discussion on Western military forums. Many retired U.S. and British military personnel have wondered whether intelligence is so sophisticated and whether those responsible for guiding missiles to their targets have become victims of primitive deception by relying too much on digital technology. Photo Al Riyadh. And so the Americans would like to know how things were with their predecessors from Saudi Arabia, but, apparently, pride does not allow this. But three years ago, the central pro-government newspaper of the kingdom, Al-Riyadh, prepared a lot of material about the military antics of the Houthi rebels, who have now become the main political and military force in Yemen, divided by civil war. . . And that they import missile parts into many small transport dhows and assemble them locally in mini-factories set up in the Yemeni Highlands. The fact is that the main warehouses are hidden in caves and mountainous areas and have long been moved deep underground. This is no joke, seven years of almost daily bombing. And at the same time, since 2015, the Houthis have been actively using models of varying degrees of probability and constantly calling on the Saudis to fire high-precision missiles, slipping them such ships. Photo Al Riyadh. Such military tricks have been used since ancient times and are still capable of fooling even the keen electronic vision and sensitive sensors of reconnaissance drones and billion-dollar military satellites. I don’t know to what extent Ansar Allah’s information corresponds to the fact that their missile potential was almost unaffected at all, but the story with the plywood “products” turned out to be funny. And the ongoing attacks on merchant ships by the US, UK and Israel make it clear that they are better off not venturing into these waters. Previously, the Houthis often simply missed, but now they strike almost every day. Damage from such attacks is minimal, and the Yemenis do not appear to be planning to sink ships. But even such impacts are forcing shipowners to change routes and insurers to do everything they can to prevent commercial ships from being sent into these waters, through which 12% of global trade passes.
