Stretch Ceilings

Published by:

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.

Language Turbo Pascal

Published by:

Object-oriented programming language Pascal was invented by N. Wirth in 1968 and was originally intended for teaching students programming skills. Although the creator of the language states that language Pascal is a much more opportunities than just training. Official publication of the language was made in 1970, after which the language became widely known. Over time, began to create a variety of dialects. The very first was a dialect of UCSD Pascal. This dialect has given life to such things as modules, accessing files, strings of different length, and others. In the early 80's by Borland was create a second dialect.

It was used in the programming environment, Turbo Pascal and more expensive environment Borland Pascal. In After 80 years in language capabilities were added to facilitate object-oriented programming. The latest version of Turbo Pascal was officially released in 1992. After her came a new version of the programming language – Delphi. Initially, the language used in the Delphi development environment of Windows. However, the developers at Borland released a product designed for the development of Linux.

This language was named Kylix. After the third version of the latest released Kylix, its development was stopped. The real breakthrough in the development of Pascal was the creation of compilers. They provide more opportunities for programming and have contributed to the portability of programs. For example, the famous, Free Pascal allows you to work in Turbo Pascal and Delphi. There is also a version of the language PascalABC.NET, which is a programming language for the platform, Microsoft.NET. This language was invented in the Southern Federal University, Associate Professor Mikhalkovich. In addition, there are so called language interpreter. For example, Larry Pascal, allowing you to create applications for mobile devices. The development of an interpreter was engaged in a talented developer, but he soon abandoned the development this project and gave the source code to other developers. More information can be found on our Turbo Pascal.

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.
