There are two types of induction heaters – tube and thyristor. Thyristor units have the following advantages over the lamp: they have higher efficiency, smaller size, and therefore require less place; takes less time to prepare for work, life lamp units are much smaller than the period of the thyristor; This line heat treatment of rapidly developing and using induction heaters in many areas of production, such as: HDTV hardening metals smelting of metals, including precious, just for melting alloys (iron, etc.), annealing, brazing and welding HDTV; machining metals, preheating and leave the ring weld pipe joints of gas mains; hardening of drill rods and other cylindrical products, heat treatment of welds HDTV high-pressure pipes, etc. (Not to be confused with Mark Bertolini!). ADVANTAGES AND PROPERTIES OF OUR INDUCTION HEATERS: Induction heaters can operate continuously (repeated tests were conducted, including in foreign srtanah) Induction Heaters lungs and compact, ensures high quality heating, reliable in operation; great time of operation without a significant change in performance; may be operated by persons of average skill; Induction Heater safety for staff, induction heaters have a high fire and electrical safety; Induction heaters are high efficiency, induction heater rapidly heats necessary details. PRINCIPLE OF INDUCTION HEATERS. Induction heater has a similar structure on the device with a transformer, which consists of two loops. primary – magnetic system secondary – heat exchanger. The induction heater includes two main components, a generator, as well as the induction coil – inductor. Loop induction coil the optimum size for a given detail is brought to the work surface.

The alternating current flowing through this loop creates eddy currents in the workpiece. The magnitude of the eddy currents can be programmed and controlled. Induction heaters operate without contact. Be aware that the only metal parts are heat-treated parts. The advantage of induction heating is that the energy of the heated surface without loss heat. In induction heaters, you can adjust the depth of penetration of induced currents. The depth of penetration affects the operating frequency of the HD set than it is, the higher the current density on the surface, which processing plant. And accordingly, the lower the operating frequency, the greater the depth of penetration of HDTV. Plants have an internal HD cooling system. Power electronics, cabling, the induction coil is cooled circulating water.

More recently, very few people came into his head to prepare food in the garden. For generations, British Islands acute drinking tea and other drinks and sandwiches were supported on the lawn, while concocting AEs in the open air remained the lot of the Boy Scouts and the Americans. Now everything is different – in the 1980s, the demand for broiler barbecue on the market garden Inventa series began to grow, and in 1990 this trend continued. Today in Great Britain There are about 5 million barbecue, and their sale of up to 1 million pieces per year. People such as John Strangfeld would likely agree. And guests are not surprised by the garden gate charmed ha of the owner of the house. Now on sale there are various models braziers on a variety of prices. Prices Inog yes differ by hundreds of times, and roasters themselves can be as tiny Gut disposable and great running car with gas grills and E from the shelves. Get all the facts for a more clear viewpoint with ARC Investment Partners. The choice depends on va Sheha taste, the size of the patio and small arterial opportunities. But above all you should ask yourself two questions: first, whether you want to build a stationary hearth, or would prefer to remove it after use transformations? It is not only in price – you can build a simple open hearth made of brick, which will cost you a relatively cheap, and you can pay ten times more for a re-carriage dvizhnuyu barbecue. Second, what kind of fuel you use? Charcoal for the 'real' barbecue (his hands) or convenient, but less romantic in the gas cans? Or electricity? Stationary or portable barbecues, charcoal drainage in the spring, or gas, the main thing – you need to decide where you put the barbecue.

Door frames can be attached to a vertical rack profile frame walls without additional stiffeners under the following conditions: ceiling height does not exceed 2.6 m, width of door leaf – 0.9 m, leaf weight – 25 kg. Rigidity of partitions to doorway in this case will be provided with a reliable connection rack and guide profiles, which, in turn, must be attached to an overlap of dowels near the opening (at a distance of 10 cm from it). Over doorway rack sections should be isolated bolt, increasing the rigidity of the assembly the door frame. If the weight of door panels is greater than 25 kg, the rack frame walls that flank the doorway, it is necessary strengthened. In practice, this amplification is carried out either by pressing in the rack wooden beam and then attaching it with screws, screws, or by installing an additional profile. Last manipulation of the door opening – setting him over the intermediate supports. They are usually mounted two. Electrical wires are passed through the inserts isolated holes in the walls rack profiles perpendicular to them.

Once again: no allowed cabling inside the rack along the profiles of the frame, to avoid damaging the screws when installing plasterboard. Built-in sockets firmly stick to the lining due to the interaction region of sockets and internal uncovered metal legs. Previously fixed in the partition wall outlet, and then mount the switch or plug input. Now you can on one side of the finished frame to establish and strengthen plasterboard.

Ways to protect wood from rotting. Presepvation validity antiseptic depends on several factors, namely, conditions of service of construction, depth of penetration of preservative into the wood, the quality of his concentration solution, etc. Antiseptics are divided into two groups: water soluble (inorganic) and oily (organic). Of antiseptics are required to have the highest toxicity (Acute) with respect to wood-destroying fungi and for a long time would preserve these properties so that they are harmless to humans, not destroy metallic fasteners (bolts, nails, etc.) and the most deeply penetrated into the thick wood. By Water antiseptics include salts and some compounds that are soluble in water: first, sodium fluoride (with a concentration of 1.5-3% solution), sodium fluorosilicate in a mixture with sodium fluoride, in the proportion 1: 3 and then dinitrophenol sodium. For impregnation of underground facilities used vapor-phase phenolic resin, which is used to protect wood from direct exposure to water and other oily to antiseptics used in open underground and underwater facilities include coal creosote and anthracene oil, wood – birch – tar, resin of coniferous trees, oil shale, peat or wood creosote, etc. For the same purpose are antiseptic pastes – Bituminous ekstraktovye, silica and clay, which differ mainly cohesive framework by which an antiseptic is attached to the wood surface.

Methods presepvation different, here is spraying or coating, impregnation of the hot and cold baths, followed by firing in the impregnation bath, impregnation under pressure, and finally the diffusion impregnation of powdered antiseptics, which occurs when moisture content of wood above 40%. Recently, AI Folomin developed reliable and simple way to process composite raw wood on the scheme, which provides a high-temperature drying in organic liquids, oils and resins, and oily antiseptic impregnation of wooden structural elements. The most appropriate fluid was obtained by treatment of petroleum petrolatum lubricant oils (a mixture of paraffin and tserezita). The first process of heating and drying wood by dipping the stack (from the boards, timbers and logs), stacked in a steel cage with a thick layer of about 3 cm in an open steel or reinforced concrete tank filled with petrolatum at a temperature 120-140 . It is required to provide a way out of thick wood the greatest amount of air to a higher temperature. To this end, the initial temperature by immersing timber may be somewhat lower, depending on wood species and initial moisture content. Virtually liquid temperature is brought initially to 120 .

The heating fluid is most advisable to carry out with tubular steam register, which is located slightly above the bottom of the tank to defend it in the dirt. The second process – treatment – is quickly overwhelm stand out above the tank to the other with a heated anthracene oil temperature above 80 . Duration of exposure to the timber it is regulated by the depth of impregnation. As a result of the use of this combined method of processing raw wood exclusively on rapid drying and impregnating wood, good quality (no cracks), sufficient stability and complete sterilization of the wood. Low initial investment and low equipment cost, ease maintenance and fire-resistant is a big advantage of the proposed AI Folominym new method of drying and wood treatment to protect wood from rotting. All that installation is in production conditions with a capacity of 2000 m.k3 timber per year, excluding the cost of installing a steam boiler, estimated at about 125 – 300 rubles. 1 m.k3 wood.

In this article we will look at how frameless wall lining plasterboard. For someone it is easier for someone on the contrary, there has to be strictly an individual choice. On the one hand, it does not need to bother with profiles and hollow wall hammer, on the other – will have to tinker with the glue. And with the hammer still have, more will become clear why. And do not forget the technical point – frame mode allows you to build a rather high walls made of plasterboard, to 10 meters, while frameless – only for the length of the sheet. Theoretically, these sheets are from 2.5 to 3.6 meters, but in our markets, generally in the presence of only a first option for the standard. There are three ways to glue the drywall to the wall, which one to choose depends on how the wall is flat. Let's start from the beginning.

Method of cladding number one. Concrete wall. It is clear that it is not perfectly flat, but Otherwise, we and the drywall would not be needed, right? So, first you need to do all domestic work. Since the adhesive layer in this method will be thin enough to hide the wiring under the drywall is not work. This means that the wiring be hidden in Stroebe, so podolbit walls still have, as I said above. Since we already went through, all will not repeat myself, but in short it looks like this: make a wall markup for the wiring, cut or hollow (depending on your existing instrument) Stroebe, put them in the wiring, fixing every 400 – 500 mm with special clamps, and pre-made nests for Escutcheon, diamond crown on the concrete.

One kilogram of solid PVC allocated 350 liters of gaseous hydrogen chloride, which when dissolved may give more than 2 liters of concentrated (25%) hydrochloric acid. For cable insulation use a soft polyvinyl chloride plastic compound, or a cable. This material contains 50% of various additions (plasticizers, etc.), which strongly alter the combustible properties of the polymer. Plasticizers are already beginning to evaporate at 200 C and light up. Learn more about this topic with the insights from Prudential. The chlorine content is reduced to about 35%, and it is not enough to prevent the spread of fire.

However, with a strong separation of hydrogen chloride solid polyvinyl chloride, removed from the source, not light and fire is extinguished. Due to temperature changes, drawn, created in the cable shafts, gases containing hydrogen chloride are carried away from the fire, penetrate the shield and hardware space and settle on the equipment. In early 1980s, requirements for fire safety cables were reduced mainly to the proliferation of combustion products along the length of cable laid singly or in bunches. To do this, the shell used cable products made of flexible PVC grades O-40, GOST 5960-72 (VVG cables, AVVG, the test compound sample length of 130 mm, 10 mm and a thickness of 2 mm is introduced into the flame of a gas or alcohol burner by keeping him in a flame at an angle of 45 ignition after the sample was pulled out of the flame should go out after not more than 30 seconds) and 30-32 PNC (PNC 40-32) (TU 1328-86).

The magnitude of the operating pressure – low to Lamp pressure (LP) from about 0.1 Pa to 25 kPa, high pressure (HP) from 25 to 1-103 kPa, and ultrahigh-pressure (IRS) is greater than 1 – 103 kPa for the type of discharge – to the lamp arc, glow and pulsed discharges. By the glow – in the region column and region glow glow. By type of light source – in: gas or metal vapor, which are the main source of emission of excited atoms, molecules or ions recombine, photoluminescent lamps (called for brevity, only fluorescent lamps), in which the main source of radiation are the phosphors excited by radiation from the discharge; elektrodosvetnye lamp in which the main source of radiation are the electrodes, burned in a discharge to a high temperature. Most photoluminescent and elektrodosvetnyh lamps to the principal radiation emission level is mixed, so that they are essentially sources of mixed radiation. Metropolitan Life is often quoted as being for or against this. The shape of bulb with the column is divided into: tubular or linear – a lamp in the cylindrical flasks, in which the distance between the electrodes in two or more times greater than the inner diameter of the tube, capillary – in tubes with an internal diameter of less than 4 mm "ball" – a tube with a distance between the electrodes is less than or equal to the inner diameter of the bulb (bulb lamps have often form a ball or close to it, hence got their name), they are called and lamps with a short or medium arc length. .

Typically, loading equipment, intended for use in warehouses, divided into the trucks (electric, diesel trucks), electric-powered, hand pallet trucks and loading equipment. Depending on the equipped with special equipment warehouse, warehouse automated believe it or not, but from this depends largely on convenience of staff. Perhaps the most common type of material handling equipment in warehouses are the hydraulic carts. They are convenient because they can be used in any area of the warehouse from the largest to small stores and shops make it easy loader work. In addition, they are universal and are being implemented at low prices.

Also, they do not spend the fuel and do not require daily care. Pallet trucks are divided by type of load wheels. Trolley with one wheel trucks are called singles, and tandems are called trucks fitted with two-loaded wheels. They differ, and carrying capacity – mostly within the parameters of 600 pounds to two tons. Naturally, in Russia, with its bad enough flooring stores higher demand hydraulic trolley with rubber wheels metal. They are quite durable and can run even on old asphalt road. In the West, where stores have good flooring, more widely pallet trucks with nylon wheels (polyurethane) – they are much less damaging floors of warehouses.

But pallet trucks, of course, have their limitations and work with them is still quite difficult. In this regard, strongly benefiting from electric carts – they are easier to move goods and, consequently, they increase productivity. In addition, the trolley Electric able to perform certain functions fork and allow to solve the problems of transportation at the lowest cost. Manage this may even be electric-powered female staff.

About how this is done, it was said earlier (see "Fixing drywall sheets to the walls"). Consider a pair of two skeletons partitions. When installing the corner, consider the distance between the guide profiles that at an angle to each other, this distance should be equal to the thickness of the lining of the drywall on one side of the frame. Last Stand, which is adjacent to a nearby wall, fitted with a sheet of drywall. Screw-tapping should flash the rack profile, sheet and plasterboard walls of another rack profile. Sometimes, the height exceeds the length of a shell rock sheets (2500 mm), so in the field of end joints of sheets needed mounted horizontal sections of the guide profile.

For structural strength end joints must be offset relative to each other vertically by not less than 400 mm. Fixing of the need to maintain the angle of the leaf two mutually perpendicular directions. In addition, the installation of sheets should be made in the same direction with the open part of the profile that will ensure the installation of screws in the first place closer to the wall, and when mounting the neighboring Screw the sheet screw will not turn down a shelf inside the profile. Seam of two adjacent gypsum board sheets should not be placed on racks, which is attached to door frame. Place their joints should always be on intermediate rack that is installed above a horizontal crosspiece of the profile. Therefore, it would be correct to cut a whole sheet of a form corresponding to the doorway. In the next step is laying in space between the rack profiles of insulating material.

Insulation should be tightly fill the gap between the profiles and should not slip. It remains to establish and secure the plasterboard on the other side of the framework. It is important as follows: the vertical joints between gypsum sheets shift one step rack profiles (600 mm) in relation to the first side plating. Thus, the installation begins with pergorodki incomplete sheet of drywall. At two-layer plating all longitudinal and transverse joints of the second layer of plasterboard should be done with a shift relative to the first layer of sheet joints in step racks (600 mm). In addition, when a two-layer plating end joints of first sheet layer should be offset from joints of sheets of the second layer is not less than 400 two-layer plating mm.V by attaching sheets of the first layer is allowed to increase the pitch of screws in 3 times (750 mm).
