Repair Structures

Such designs are called the svarnolitymi or stamped and are widely used in aircraft, automotive, car building and other areas. The use of such structures provides a saving of metal and labor. By welding details can be made of metal, held a variety of pre-processing, for example, welded rolled profiles with stamped, forged or cast blanks. You can weld dissimilar metals: stainless steel with carbon, copper and steel, etc. In the manufacture of complex-shaped structures using welding instead of forging and casting gives a big economic impact. For example, labor productivity in manufacture of welded structures is 2 times higher than the casting and forging and stamping, and working conditions are much better.

Capital investment per ton of welded structures are 1.5-2 times lower in cost and 1.3-1.6 times lower than in the foundry production. By reducing weight, increasing reliability and durability of products. 4.Udeshevlenie technological equipment. The welding equipment is relatively easy, relatively cheap and very high. It reduces the capital costs of metalworking plants and accelerate their entry into force. 5. Facilitating the integrated mechanization of mass production of the same type of welded products, the ability to create mass production with 100% automation and mechanization of the production cycle, which dramatically increases the removal of industrial output per unit area of the shop.

6. The possibility of broad primeneniyav welded constructions progressive modern types of materials: high strength, lightweight curved profile, multi-layer sheet steel, light alloys, high purity metals, etc. 7. Facilitating the production of components and microminiature parts in the manufacture of certain types of products – semiconductors, etc. 8. The possibility of widespread use of welding, surfacing and cutting the repair where the metal treatments provide a quick and cost-effective to restore worn-out, the failed equipment and damaged facilities. 9. Tightness and reliability of welded joints. 10. Reducing industrial noise and improve working conditions in shops.

Stretch Ceilings

Stretch ceiling is a product made from a certain strip of PVC film fabric that are made exactly the right size room with a view of its characteristics. The density of fabric, usually is 0.17 inches. Plans for cutting must performed an experienced technologist, because in this area, as well as some other points related to suspended ceilings, a lot of subtleties. Holes for fixing the pipeline, the chandelier, near the air vent and fire sensors in the film are cut and glued reinforce special fasteners. The canvas is attached to a plastic profile, mounted on the walls of the room. The service life of the tension of the system – the installation of 3 years blade up to 15 years. Last time used to repair apartments in Sevastopol history stretching ceiling shows the entire history of a stretch ceiling and the story of his birth, moved forward force for progress are practical and aesthetic human values.

Fantasy designers and their experience of building more of ancient Rome, driven by aggressive patricians, gave birth to the idea of draping a cloth ceiling. Matter of tissue picking the color of the walls of the room, and when eventually faded fabric, covered with dust, sag or simply bored her changed to a new ceiling and looked like new, too. Another more recent ancestors stretched ceiling – it ceiling made of cloth in ancient Armenia, where nachale17 century began to use stretched on a frame that is impregnated with chalk, and calico. Drying up, she gave and received a draft of perfectly smooth ceiling. Modern suspended ceiling appeared for the first time in France about 40 years ago. Principle stretch ceiling installation of PVC film for a very long time, entered the list of industrial technology and helped to solve individual problems in the field of decoration of ceilings, that were previously intractable.

Tsynbal Rating

But, of course, guarantee by such means manufacturers can not give. One of the certified impregnations, appeared on the market of St. Petersburg, became a flame retardant BATH-1, developed and manufactured since 1993, JSC "Neohim." Originally part of produced in an aqueous solution, which, of course, was ineffective, as the objects that are handled by staff, had to carry plenty of water. Recently BATH-1 is produced as a dry powder that is diluted by place. Eugene Tsynbal: 'In our surface impregnation of wood allows you to transfer to the second group of fire-resistance rating.

Initially membership was created to handle the attics, which are just and should be such a group. And if we put the wood in the 20% solution, then, within two hours of deep impregnation occurs, which will translate the material in the first group of fire-resistance rating. " Sergei Tsvetkov: 'Impregnation under pressure – the Most promising way to protect wooden structures. Wood "canned" impregnation solution penetrates into it deeply enough. When a surface impregnation, after rassushivaniya layer is destroyed, the protection disappears. And when the pressure impregnation is guaranteed "the integrity" in the cracks of up to 1.5 cm.

At the same time – and this is important – the mechanical properties of structural treatment has no effect. " It is known that the first group of fire-resistance rating using the impregnation depth is achieved only through the autoclave. If you make a surface impregnation – the tree will receive only the second group of fire-resistance rating. However, in most cases deep soaking to impossible: not every structure can be disassembled to such components to each can be loaded into a special bath. Incidentally, before the processing of raw materials took place already at woodworking plants, and when the tree was going to construction sites, it has already been processed and had the right group of fire-proof performance.
