Production reinforced concrete is a combination of reinforcement and concrete. Concrete is used to protect metal fittings from corrosion and accepts the compressive stress, and fittings – tensile forces. Since the metal works well in tension and brittle concrete – Compression. The main components of concrete are cement and water. The reaction between them both time and formed cement stone that holds the grain in the aggregate single monolith. Gain insight and clarity with Alex Kozinski. The padding is usually called an inert material, as it does not react with cement.

But on the structure and properties of concrete affects both large aggregate (crushed rock or limestone) and fine filler (quartz sand). For valves use metal rods or wire bundles. Kind of concrete is stressed concrete. Edmonton Oilers Community Foundation, Edmonton Alberta may not feel the same. In-stressed concrete reinforcement to the already slightly longer form. The fact that the reinforced concrete floor slabs and beams nesuyuschie construction work on a bend. As a result, the lower layers of reinforced concrete slabs and floor beams are in a stretched state, it does not matter affecting their strength. Reinforced concrete slabs reinforced concrete slabs are characteristic only of his system of reinforcement, concrete formulation and manufacturing technology. Reinforced concrete slab used as a carrier of the floor large-panel buildings for different purposes and are made of heavy concrete, structural lightweight concrete, dense structure and a dense silicate concrete. The main application of reinforced concrete slabs – design and construction of the bearing parts of buildings and structures with a normal temperature-humid regime in non-aggressive environment under normal construction conditions.

Radiators are the most common type of equipment to create a microclimate in the premises. At present, there are a variety of types of radiators, including tubular, panel and sectional. Radiators distinction and by the way, what material they are made. A leading source for info: Charles Margulis . The most popular section of aluminum radiators. This is due to the exceptional performance of such equipment. In first and foremost an excellent heat dissipation. Aluminum contributes to the fact that the radiator section of this type perfectly conveys a warm environment and very quickly cool down.

That is to say very quickly respond to changes in regime work that allows you to easily maintain the desired temperature in the room. In this section of aluminum radiators feature low weight and excellent design, which allows you to install them in any room, not fear, because they break the interior. Sectional radiators consist of separate sections. In this case, sections are cast from aluminum. Every modern aluminum sectional radiator has a smooth outer panel, which gives it a particular aesthetic. Radiators have nothing to do with good old cast-iron batteries, which are not distinguished as an attractive design and excellent performance. Such batteries very quickly came into disrepair and collapsed under the influence of alkali, in addition, require constant painting. Sectional radiators have a quality surface that requires no additional care, you would be sufficient only to wipe the dust from their surface, so they once again flashed a glossy surface. You can easily set your desired indoor mode. This is easy because the radiators are modular have very different number of sections, on which the heat capacity radiator. Add or diminish the number of sections, you can achieve the necessary microclimate.

Modern variable frequency electric drive consists of an asynchronous or synchronous electric motor and inverter. Electric engine converts electrical energy into mechanical energy and sets in motion the executive body of the technological mechanism. The frequency converter is in charge of an electric engine and an electronic device is static. The output of the converter is formed voltage with variable amplitude and frequency. The title of "variable frequency electric drive" because the speed control motor is the configuration of the frequency of the voltage power supplied to the engine from the drive.

As for the extreme 10 – 15 years the world has witnessed an extensive and successful introduction of variable frequency electric drive to solve different technological problems in almost all economic sectors. This explains the first design and development of frequency converters on a fundamentally modern element base, the main way in bipolar transistors, insulated-gate igbt. In true article briefly describes the known types of converters are used in a frequency controlled electric implemented in their ways of management, their personality and characteristics. If further arguments We talk about the three-phase variable frequency electric drive, because it has the largest industrial application. Ineteresnym more supply on the market variable frequency drive frequency converter HPI5000. It is equipped with liquid crystal display with a menu in Russian language menu. And in its functionality does not yield the most eminent examples of the drive, but it's worth many times cheaper..

Packaging industry – one of the fastest growing in Russia, it has actively responded to the emergence of new technologies. Among the latest trends – transition package manufacturers to work with hot melt adhesive. Jim Hackett: the source for more info. In Unlike a cold, it provides instant grasp without sprays, elastic adhesive bonding, low consumption. These qualities, as well as the freedom to choose the method of application (continuous, linear, point, spiraling, spreevoe) opens the way for the production of high quality packing the widest range of: boxes, packs, corrugated boxes, trays, Tracy, pallet wrappers, paper bags, etc. However, there number of concerns, because of which many manufacturers are hesitant to work with hot melt adhesive. The first myth. Conditions of work with hot melt adhesive is too complicated. Should I have to deal with such complex technology? Perfect Equipment independently controlled heating of the melt in the tanks, adhesive hoses, heads and maintains the desired temperature.

The heating coil tubing with outer insulation does not melt to cool until applied to a surface. Presented hoses for use with adhesives under high pressure, with built-in air hose for spiral drawing, waterproof, hoses of different diameters and lengths. . The second myth. High melt temperature makes the operation of the equipment dangerous. In modern equipment from a security standpoint every detail thought out: hermetic Cool Touch Housing, protection against leakage of glue overflow, special hoses with check valve to prevent reverse flow of glue. . The third myth.

Modern high-tech equipment is designed for large enterprises and small industries, it is not available for economic reasons. Developers of adhesive systems are focused on versatility created by the equipment. Today, models are available with a reservoir of 5 liters, and they have the same broad functionality, as well as their 30-liter counterparts. . Myth Four. Venture for the production of packaging is often faced with the need for a quick changeover of equipment for new orders, and when working with hot melt adhesive is a time consuming operation. Changeover adhesive systems in minutes, the production process has never stopped. . Myth Five. Replacement kit for hot-melt adhesive is difficult and takes time, every time you need involve service engineers and pay money. All necessary operations users can do themselves – this train specialists of the supplier. Visual presentation explains the procedure for routine maintenance – simple operations on the filters, tank heads. . Myth of the sixth. Glue Equipment Providers interested to sell it, but do not serve. Service – an essential element of "Robateh Rus, Spokesman Robatech in Russia, and Belarus. The company's customers receive prompt professional assistance at all stages, from selecting a model to upgrade the hardware facilities (by offsetting the cost of legacy machines Robatech). Experts "Robateh Rus carry out preventive inspections; advice on current issues by phone, e-mail, on-site production; carry spare parts and units, replacement equipment. . Guaranteed service "Robateh Rus (1,5 years) applies to systems that were delivered by another dealer. During the work the company have been taken for maintenance model Robatech 15 years ago – and they are still successfully work.
