Powder Coating

Powder coating of metal is already used in industry as one of the most reliable and cost-effective methods of applying protective coatings. And we are not surprised to hear that parts of the car or constructions have completed the powder coating. Quality and durability coatings are widely used in areas where colored objects uses a lot of people. Please visit Ray Kurzweil if you seek more information. For example, a staircase in shopping mall – how many people each day goes on it? Tens and hundreds. Mitchel Resnick is open to suggestions. It is clear that the usual coating wears off quickly, but the powder coating can stand (unless it is made to the technology). However, the scope application of powder coating is not limited to industrial production and mass use of objects. In fact, powder coating has been successfully used in smaller scale.

The most simple Example – steel doors, which now stand at almost every apartment. More information is housed here: ConocoPhillips. If the manufacturer claims that the metal surface applied anti-vandal cover, you know – here we used powder coating. Only this technology makes it possible to form a solid layer of paint so that it can successfully withstand any mechanical stress. And note that the decorative features of the powder coating does do not suffer. Modern techniques make it possible to achieve different visual effects, including such complex, like a chameleon or tissue. The process of powder coating metal can take place in different ways: for today developed many ways of coating literally on all occasions. Of course, in specialized shops is used for this high-tech equipment, which not only provides high quality, but also an unprecedented low percentage of waste. However, there are manual settings, sprayers, allowing strike coverage on small items without opening the entire pipeline. With all of this powder coating is available for the average consumer – most shops take orders for staining single products and small parties.


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. 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.


The destruction of aquatic lmb also gets much cheaper than businesses, compared with organic coatings. Price per square meter or a kilogram? If we consider the cost-effectiveness, it is very often paints with a low price per unit of volume gives a significantly higher price of paint, the more dear, how is it not strange that sounds. To deepen your understanding ConocoPhillips is the source. If the lmc has no consistent method used application or poor technological properties, even when using professional equipment for painting will not affect the situation. Calculate the approximate figures for the cost of painting, only after the trial painted a number of industrial designs painted products. For example, using as the application method refinishing, one of the main indicators of technological painting to a mass transfer process – part of lmb, falling on the surface be coated products and taking part in the formation of a decorative coverage.

If the manufacturer claims that they produced coatings are designed for any application method, mass transfer is likely to be 20-30%, while at the same time, high-tech coatings produced by spraying it under the mass transfer lmb 70-80%. Only one analysis of mass transfer is able to align costs coatings with different price per unit of volume or weight, and factors such quite a lot. Finished color or tinting of ral? If this painting is made to order and variety of coated products has several dozen, then because of the lack of operational tinting, can increase the financial zataraty for making stock lmb. Even if the possibility of tinting on the ral is provided, you must ask: Are the mixing system color paints or tinting pastes, how many colored inks or pigments necessary for the formation of the entire catalog RAL; what effects (metallic, pearl) provides paint manufacturers, is available or not hand-coloring in ral or required to purchase equipment. It should be noted that the paint manufacturers for the tinting on the ral must clearly recommend pigment pastes for which agreed to be supplied lmb inconsistency pair of paint – pigment paste will, at least, to overrun and paints and pigment pastes. Of course, this affected only a small fraction of problems to deal with that would be necessary at the time of selection of industrial coatings. But the lack of knowledge, namely, to describe a moment leads to serious financial expenses at the time of the preliminary simulations.

Windows NT Operating

4. Use of management systems of the operating system Windows nt Windows nt is not a real time operating system, because it does not have a sufficient range of priority flows (threads), can not control the priority inheritance (blocking the flow should inherit the priority of the thread, which he blocks), the mechanism to synchronize threads unpredictable response time to an interrupt is unpredictable. Meanwhile, because of the growing popularity of management systems Windows nt operating system problem as something to be solved. Of all the existing proposals for the implementation rtos for Windows NT-based practical significance of the two approaches. The first approach is to run Windows nt in the form of low-priority tasks real time operating system (supervisor). This assumes the use of nuclear classical type of rtos qnx or VxWorks. There are decisions in which a supervisor uses Vx Works. The second approach is to expand (in the sense of real time) Windows nt.

This may be an original development manufacturer management system, the system is WinCAT ( Industrie Electronic, Germany) – Another variant is the use of cots solutions, such as rtx 4.1 firms VenturCom. Both approaches have their advantages and disadvantages. However, the approach based on the expansion of the real Time for Windows nt is still more promising. First, the expansion use the same types of objects for managing tasks, that of the core Windows nt (myuteksy, semaphores, etc.). In contrast, the Vx Works uses the original function and mechanisms that shape his own style, different from the style of Windows. Secondly, there is no need for the second operating system, which reduces costs and eliminates installation problems and docking of the two operating systems on one personal computer. Decision in favor of real-time extension allows you to quickly update the control system with new versions of Windows nt, carry a powerful protection for applications that Windows is using Independent Abstraction Layer hal, easy to debug code and use of standard Microsoft arrangements for information exchange between Windows and real time tasks (1RS, interprocess communication mechanism, ole – a mechanism Object Linking and Embedding, com – the mechanism of component models, rpc – Remote Procedure Calls).

5. Scheduling strategy based on expansion of rtx (Real Time extension) One of the most reliable and popular algorithms scheduling in multitasking operating systems (OS) – a cyclic scheduling algorithm, where for a particular task is given a time slice (time slice). At the end of each time slice scheduler scans the queue of active tasks and decide which of them to transfer control. Such an algorithm can be used in the numerical control.

Uninterruptible Power Supply

Everyone who uses electricity in the home at least once faced with its sudden shutdown. Are we looking tv, wash clothes there, working on your computer, or prepare food, no electricity can seriously interfere with our plans. Residents of large cities, where better to work established for such services, may still be hope for the prompt elimination of the causes of unplanned outage. Although if an accident Seriously, they have every chance to remain without electricity for a longer period. What can we say about the countryside? Responsiveness of local services and organizations in charge of the repair of power systems significantly lower. This is due to close completely objective factors: the large area of services, lack of qualified personnel, problems with transport, and sometimes with access to facilities in need of repair, poor logistical support. The reliability of electricity supply in rural areas can affect the human factor.

For example, use housewifely peyzanin lack of privacy and ten meters wires, pointless, in his opinion, leaving the forest. Another, hearing that transformer oil prevents rotting wood, and even take leave without it standing alone transformer substation. As a result, two or three horticultural associations will live without electricity for two months. Yes, these stories seem implausible, yet they are absolutely real. It turns out that the electricity supplier is simply unable to provide uninterrupted power supply. But what if by 'power' will be turned off such important facilities as hospitals, operating services, enterprise continuous cycle? Operating today Electrical Code (PUE) classify electricity customers in three categories of power supply reliability.

Belgium Material

It is needed when working in the winter on the new concrete cover, humidity which bring to the regulatory parameters is impossible. In applying the 'breathing' roof in mass construction necessary for the project of roof design scheme of the device roofs showing layout of the layers and structures of nodes and adjacencies. Partial attaching the roof to the ground can be achieved by applying the lower layer: the perforated material, the usual material, pasted mastic as a uniformly distributed spots, continuous or broken bands mastics surfaced material that has surfaced bottom layer applied to the canvas by broken bands of 'breathable roof' has been successfully applied in Scandinavia, Germany, Belgium and other countries. When laying the material by or to meet technology needs to pay attention to the fact that he had a sufficient thickness of the lower cladding layer. The minimum thickness shall conform to the size of the irregularities (roughness) screed base.

Very tech devices from the roof membrane materials with an adhesive layer. Such a method may apply to both new roofs and repair old ones, but the base should be prepared with great care. To date, these materials are rather a rarity in the Russian market and apply is very limited. Roofing mastic of bitumen-polymer and polymer mastic can be applied to various surfaces (steel, concrete, asphalt) of any, even the most complex configuration (pitch, which laid mastic are not limited to, down to the domes and steeples). But there is one important condition: the surface must be perfectly flat, otherwise it will be impossible to achieve the same thickness mastic cover. This The biggest drawback mastics. Mastic is applied to the base in liquid form. After solvent evaporation, it solidifies, forming a continuous seamless waterproof film.

Thickness of the film depends on the number of solids in the mastic. In mastics, whose composition does not include a solvent, curing occurs without reducing the thickness of the deposited composition. Pay attention to the fact that the roof slopes more than 12% and temperature Outside air above 25 C in the mastic is necessary to introduce special fillers, which increase the viscosity (thickening agents, cement, etc.) Modern types of cements do not require a protective layer, as dyed they have necessary decorative properties, and the material itself rather resistant to weathering. If you need to protect the roof from mechanical damage (traffic areas, installation of engineering equipment, etc.) a protective layer of gravel (10-20 mm), coarse sand (2-5 mm), small-sized asbestos or bitumen sheets, etc. The ideal protective layer is a river pebble. And yet. Do not trust the installation of a roof at random people. Trying to save money on the project, as the material and pay workers wrapped triple costs. This applies to any type of roofing. Criteria for selection of firms tend to: availability of licenses, warranties, contracts with timelines, readiness to conduct a preliminary study designs and in writing inform the customer about possible problems, a willingness to intermediate inspections and a high level of communication culture.

Pipeline Valves

At first, understand with the concept – that there are valves. This device, mounted on pipes, tanks, boilers and other installations designed to disable, distribution, control, mixing or discharge flow. Classification of this kind of reinforcement for the purpose: 1) industrial valves utility is used in many industries. Its purpose for the media with commonly used values pressure and temperature. This valve fitted with water pipes, steam pipes, municipal pipelines, heating systems, etc.

2) Reinforcement of special purpose – to operate at a general, low pressures and temperatures, at low temperatures, the corrosive, toxic, radioactive, viscous, abrasive or granular media. This power valves high energy parameters, cryogenics, corrosion, valves with heating, valves for abrasive slurries and bulk solids. 3) The task taps (valves) – a general and special fittings used by the technical rules. 4) Reinforcement for special order (special) is developed and manufactured to individual orders based on specific technical requirements. This category refers to and separate valves for nuclear power plants.

5) Plumbing fixtures – one which is equipped with various household appliances: gas stove, bathroom installation, kitchen sinks, etc. It has a small diameter passage, and often manually controlled (exception – the pressure regulators and safety valves for gas). 6) Ship fittings. It is available for use in specific conditions of operation of its vessels on river and sea fleet to meet the increasing demands for minimum weight, vibration resistance, high reliability, special conditions of management and operation. According to their function fittings divided into: locking, regulatory, distribution and mixing, protective, protective, and fixtures. By the method of control valves are classified into groups: 1) Automatically acting (autonomous) fittings – one working cycle which takes place under the influence of the working environment, without any foreign energy sources. By automatically acting valves include: pressure regulators, level controls, steam traps, check valves, safety valves. 2) Controlled fittings – one working cycle which is performed on the relevant commands from the outside at the times determined by the working conditions or environment. Team serves the operator or automatically operating devices installed in the system automatic process control. By controlled valves include all types of valves, control valves.
