Polycarbonate

Polycarbonate – a material that has long proved to be the good side and are now used almost universally. This kind of material is obtained by polycondensation of acid chloride carbonic acid and diphenylolpropane. Due to the fact that the derivatives of carbonic acid are carbonates, this type of material and has been called polycarbonate. Others including samsung, offer their opinions as well. Through the use of modern methods and technologies, cellular polycarbonate acquired properties that an order of magnitude properties of other materials previously used in all types of construction. Polycarbonate is highly resistant to various weather conditions. Their properties it maintains a temperature range of -60 to +80 degrees. In addition, the polycarbonate has a sufficiently high viscosity index that allows you to bend it in a cold state without possibility of deformation or loss of other qualities of the material.

Due to its structure, polycarbonate is very lightweight, almost 16 times lighter than glass, which gives him certain advantages with respect to the latter. Cellular Polycarbonate has high durability. In that case, if the installation was carried out by competent installers, the only guaranteed service life of the material is about 10 years, in fact, the term of his Service is much more than 30 years, while it retains all the inherent properties of the new material. Also, polycarbonate has a sufficiently high impact resistant properties, resulting in deformation of the material is practically impossible. Man almost beyond the power to violate the integrity of the polycarbonate. In addition, the material in more than 200 times stronger than glass, and the breach of its structure, unlike glass, does not have splinters.

Sheet Metal

Most industrial uses in products obtained with the help of metal. Sheet metal is in the manufacture of automobiles, construction of facilities, railways, manufacture of various machinery, tools, as well as construction of buildings. Sheet metal is used in various branches of human activity. Today the sheet metal did not performed manually, the process by using modernized equipment. Modern technologies allow to increase production, a guarantee of obtaining high quality parts desired shape and diameter. Sheet metal is carried out on advanced equipment, which results in waste-free production.

Sheet metal is produced by highly skilled specialists, therefore, orders are made with high quality and on time. The main advantage of sheet metal processing – production is carried out by a detailed set characteristics. Speaking candidly Viacom told us the story. The continuous growth of competition forcing companies carrying sheet metal, for innovative production technology, increase the quality of its products every day to improve the technology. The most common way sheet metal – plasma cutting. High-speed production can fulfill orders as quickly as possible.

Today, the technology of plasma cutting is the most common and cheapest method sheet metal processing. Thanks to high speed cutting, the metal does not manage to reach high temperatures, so the deformation of materials during processing is minimized. Advantages of sheet metal using plasma cutting: First – high-speed processing of the material. Secondly there is a reduction of production costs. Third, when sheet metal is no strain in the fourth, achieve an absolutely smooth surface of the product. To date, sheet metal using plasma technology is the most common and cheapest method of production.

Laval Steam

But the technical implementation process of mixing steam and water in umpeu and psa is fundamentally different. And because different principles of action considered devices then, of course, be different and their specifications and conditions of use. To clarify the effect of differences need to stay on the construction of both devices. To read more click here: Steve Wozniak. The operating principle of psa. psa consists of a steam nozzle, the chamber mixing and diffuser. Steam flow accelerates to supersonic speeds through the Laval nozzle, and then enters the mixing chamber.

The water in the mixing chamber is fed coaxially steam flow in the form of an annular jet. When interaction flows spraying water, resulting in the mixing chamber is formed of a supersonic two-phase flow, followed by transfer of momentum and heat from steam to water. Further, the resulting mixture inhibited the emergence of shock, increased static pressure and vapor condensation. Under certain conditions, the pressure output stream may exceed the pressure of input streams. Since the nozzle heat steam-power goes into kinetic energy of the steam jet, the psa can effectively work only with a large percentage of the pair 2. Thus, a necessary condition of the psa is to obtain a two-phase shock in the mixing chamber and diffuser. Therefore, in addition to accurately calculate and manufacturing duct psa must also provide an accurate job and maintaining a specified range of input fluxes steam and water, defined as the possibility of obtaining shock wave and its position along the axis of PSA: vapor pressure, pressure-water-temperature steam-heated temperature of the water-level dry steam-injection rate (The ratio of cost of steam and water).
