Sandwich Panels

Sandwich panels – a modern construction material, without which it is impossible to imagine both civilian and industrial construction. It's lightweight design, easy to install and incomparable to any material in their heat and sound insulation properties (100 millimitrovaya panel with mineral wool insulation on its thermal insulation properties of 7 times the brick wall of the same thickness). The main purpose of the sandwich panels – Protecting designs in the construction of prefabricated buildings. Sandwich panels are of the following types: wall, roof, ceiling (used in decoration) partitions, including fire; facing (used in the reconstruction and insulation of old buildings) panels for cold rooms. The application of sandwich panels: industrial buildings, warehouses, service centers, shopping malls, sports facilities, medical complexes, including "Clean rooms", the building-"fridges"; agricultural buildings, reconstruction of buildings and structures.

The design of multi-layer sandwich panels, as follows from name. The most common type – frame consisting of two shaped steel sheets, filled with insulation. The use of profiled steel sheet attached to the panel rigidity. Educate yourself with thoughts from Susan G. Swenson. As a rule, ends represent a kind of "lock" that makes it easy to mount, and in some designs to avoid the so-called "cold bridges". The most common insulation sandwich panel mineral wool, polystyrene, polyurethane foam. Mineral wool – a natural material made of silica rock melts the synthetic resin binder, and polystyrene foam – plastics. Heaters fairly waterproof, but the mineral wool as the absorbent material, yet is able to absorb moisture, which greatly reduces its thermal and sound insulation properties. To reduce this gap by manufacture of sandwich panels used vapor sealing materials.

Sandwich panels with polystyrene insulation from completely moisture resistant. The thickness of sandwich panels ranged from 50 to 300 mm, depending on the application and region-building. Weight sandwich panels as thick as 100 mm of polystyrene insulation with 1.5 easier panels with mineral wool insulation. This figure makes polystyrene foam insulation panels with a more attractive when construction, as reduced transportation costs and the load on the foundation of the building. The difference of heat-insulating properties of different insulation is low, it varies between 15% and EPS retains heat better. The level of fire resistance is higher in the mineral wool: under high temperatures, it can break down, but does not support combustion. Perhaps, therefore, a sandwich panel with insulation that are most common in Russia.

Chainsaw

How to choose a chain saw. The chain saw is needed when caring for a large garden, with firewood and for construction work in combination, for example, with a circular saw. Chain saws can cut any building materials – from timber of any strength up to lightweight concrete and PVC pipe. Most chain saws are divided into electric and petrol (the word "chainsaw" is meant mainly just gasoline chain saws). Gain insight and clarity with Confluence Investment Mgt. Among advantages of chainsaws can be noted in the first mobility tools (such as a chainsaw can take with them into the woods) and better performance due to the greater power. However, they do have their drawbacks: in chainsaws use two-stroke engine that runs on a mixture of oil and gasoline, to the quality of which the engine can be quite sensitive. In addition, the chainsaw harder for maintenance than electric chain saws. Electric chain saw – a cross between a building and garden tools can be used to cut twigs, firewood in the country, and for work on the site.

Electric chain saws are generally easier to chain saws, less noisy in operation and easier maintenance. Electric chain saw is more efficient in operation and far more environmentally friendly than a chainsaw, therefore it can replaced in some cases, such as indoors. Like any other tool, chain saws can be divided into two classes: professional and consumer. If you wish to use a chainsaw at least 5 hours a day, we recommend you opt for professional models who are represented here. The two most important characteristics of chain saws – the length of the bus and engine power. Length of bus impact to a depth of cut, mainly in the market are chain saws with the length of the tire from 35 to 70 cm power or engine capacity, depending on the size of the tire and the intended use: for example, if you're going use a chainsaw to cut knots, it suffices to 1.5-2 horsepower. For felling using chainsaw with a capacity of 2 to 4.5 hp All chain saws provides automatic chain lubrication. Oil is poured into the a special container and in the process of working through a filter is applied to the drive sprocket and chain. Depending on the hardness and 'knotty' wood require different intensity of grease – and in some models have this useful adjustment. Also, almost all modern chain saws are equipped with automatic chain brake, made as a protective shield that stops the chain in contact with the object of cutting.

RTZO CPU Application

Hot-air ducts – rotating armature with any electric (on the application of 1, 1, 1, belonging to 1). On Very Hot air ducts – throttle valve with remote Electric or complex and expensive technological fittings with high, therefore, the requirements for electric drive (on the application of 2, 2, 1, belonging to 1). Gas. The basic requirement – the presence of protection. Enough a clear distinction between drives purchased in OAO "Gazprom", with specific requirements for reliability, speed, mode of operation and resource and other drives for gas, where there is no increased requirements (on the application of 1, 1, 1, on the accessories – 1). Liquid – water. resources. The increasing demands of the drives in most cases not (on the application – 1, 1, 1, belonging to – 0). For other opinions and approaches, find out what Vislink Technologies has to say.

Liquids – oil and derivatives. The basic requirement – the presence of protection. In most cases, elevated requirements for the drive (on the application – 1, 2, 1, on accessories – 2). Liquid – organic salts, acids and bases. Very few used motors. Where high requirements are applied to the drive (on the application – 1, 2, 1, on Accessories – 2).

Streams of physical harm. The use of actuators to open the gates and shutters, where minor requirements (for use – 1, 1, 0, for supplies – 1) and used as actuators and dampers dampers (on Application – 1, 0, 0, for supplies – 0). As you can see, there are not many subsegments, which would be required most indicators on the top and accessories. Therefore, consumers and did not choose to drive more high performance. Thus, it became a little clearer, why not all people go to BMW-7 model. Now let us look at the issue of choice drives the consumer in terms of management systems. Most management systems today come back from the past and belong to a centralized management system. Characterized by discrete analog control, power switching, located in the assembly and RTZO CPU, managing multiple control loops. However, the shortcomings inherent in these systems, long forced manufacturers equipment to convert the system so that the intelligence CPU began to descend to lower levels of government, down to field level equipment. In summary: There is no doubt advanced development of "Sibmash" interesting and innovative. They have found their niche in the market TPA and its customers and admirers. However, the claim at the "textbook" that the proposed design is the ultimate truth and the only future for them, it is premature to and from the point of marketing is not very competent. Everything in business and in life is determined by utility and expediency: Well, do not carry the bricks on the "saloons" – simply for reasons of common sense. And because each company to Success should be defined with its own place – market position in coordinates "price-range of consumer characteristics" and the target customer group for which this set of properties would be the best .. Positioning, not just in marketing terms as people think. This business strategy and its philosophy. Essentially the same article – the author did a great job as an engineer-designer and an expert on marketing and, of course, it will be interesting and useful to all market participants valves.

LED Fixtures For The Court, Gardens And Streets

Today, landscape design ideas can realize even the most experienced and fastidious designer and the customer with endless imagination. Often in the courtyard you can see the whole work of art, full-fledged Eden Gardens. This beauty wants to enjoy the day and night. It is therefore necessary to provide yard lighting system and the surrounding area, which will enjoy the site and after the arrival of darkness, and also will give a highlight color and design work. Necessary to professionally design and implement a lighting system that combines different types of lighting equipment. Excellent choice here will be the use of outdoor LED lighting fixtures. By appointment lighting can be divided into floodlighting escort, technical and decorative. Each of these types of lighting equipment to apply to specific parts of the territory, the streets, but need to use a certain type of fixtures.

Lighting can perform utilitarian or decorative functions. For exterior artificial lighting used metalogalogennye, halogen lamps, or special outdoor LED lighting. What to consider when setting park lighting? What are the subtleties and nuances must be met when installing street lights? The first most important rule is to prevent the effect of glare. Often in the streets, sites and gardens can be found the so-called pereosveschenie when blinding direct light spoils the whole picture and instead of harmony causes stress and discomfort. In planning and staging of park lighting to use a sufficient number of properly selected fixtures. However, their orientation should be such so as not to hit in the eye. Optimal choice will be LED lights with a small angle of the light beam, which will cover only specific parts of the street. Another way attractive presentation of landscape lighting is hidden from the eyes of the installation of light sources.

Thus, the effect of self-illumination of the object when the light comes as if from within. But here, too, should be observe the delicate balance, subtly combining the efficiency and attractiveness of this method of installing lights on the street. Naturally, such a labor-intensive and quite hard work as the design of lighting systems and proper lighting installation itself better to entrust professionals with sufficient experience and the necessary skills and tools. Of these companies we can recommend a company Profintek, working in the market for several years and engaged in manufacturing of LED lamps according to the latest innovative technologies. It offers a wide range of LED street lamps, which is sufficient to implement any pans and get high-quality, professional results that will please you more than one day.

Welding

1.Elektrody with a sour finish. The basis of coating are manganese, silicon and iron oxides. Welding seam created by the welding electrode with such a coating has prone to the appearance of hot cracks. 2) electrodes with basic coating. The basis of cover are carbon compounds and fluorine compounds.

Welding seam is different positive effects such as plasticity, shock viscosity at normal and low temperatures. But this kind of coating has a negative quality, it is very susceptible to the formation of pores in the welding seam in the presence of scale, as well as oil on the edges of the elements. 3) Welding cellulosic electrodes. This type of coating contains in its structure a huge amount of organic components, mainly cellulose, as well as substantial amounts of hydrogen. Welding electrodes with the type coatings are used in manual welding of carbon steel billets.

4.Elektrody Rutile. This coating contains about 50 percent of natural rutile concentrate. When using these electrodes stability of the welding seam to the formation of shrinkage cracks above. Gas emissions during arc welding electrodes, with this kind of coverage is not particularly harmful to the welder. Rutile electrodes provide a powerful and steady burning electric arc discharge with manual electric welding in alternating current welding, small metal loss during spraying, rapid slag formation and good weld. Important role for arc welding and electrical industrial manufacturing of the electrodes has a graphite MPG. What is graphite? Industrial graphite – a material that represents the allotropic forms of carbon, which characterized by a particular crystal structure. In turn, this structure is precisely defines the necessary properties of matter. Graphite has a great diversity of physical properties of different types of connections carbon, due form and size of individual groups of crystals, and crystal structure. Industrial strength graphite is entirely dependent on its structure. Each field has its own graphite physical attributes. And this difference causes the difference in the dispersed structure, that is a different shape and arrangement of crystals of graphite, which compose the body. Graphite is used in many industries industrial production, since it consists mainly of carbon and always contains impurities of ash, volatile matter and moisture. The main features in the manufacture of electrodes, which has industrial graphite – plasticity.

On Mineral Resources

The problem of obtaining a license for water wells has become the most urgent in recent years. Since Soviet times, remains a huge amount of underground water intakes, operated without a valid license for unapproved stocks. Most often, the wells are operated for three to four decades and the issue of their legal registration, to a certain point, no one thought to do. In the 90s it's time to large urban artesian wells. For most of them were performed on the licensing, organization of monitoring, evaluation and revaluation reserves.

It is quite logical to expect that more will get to Rosnedra single intakes, on the balance of legal entities. What's happening. The works here – no end, but if you make long-term prognosis, then someday it will reach the common people, ie to private wells. But do not get ahead of ourselves. This article has a specific purpose – namely, to understand what must be the owner of the well, to safely issue a license for extraction of groundwater.

Fundamental point in the operation of water wells is the fact that subterranean water minerals. Accordingly, the owner of the water well used for the purpose of extraction of groundwater is subsoil. In accordance with Russian law on February 21, 1992 2395-1 On Mineral Resources", the provision of subsoil use is made of a special state permission in the form of licenses, including the prescribed form with the form National Emblem of the Russian Federation, as well as text, graphics and other applications that are an integral part of the license and determine the basic conditions of subsoil use.
