Shashel, furniture or grinder – a dangerous pest of the mass of wood and wooden buildings. This small beetle is 3-4 mm long, oblong with a dull brown, covered with silky hairs body. For the ability to produce sound like the ticking clock, popularly called "the watchmaker." This sound is heard from the wood, when my breast shield beetle hits on the wall of the proedennogo, calling a female to mate. As in the open air and in indoor beetles colonize wood 4 to 5 years old and older, preferring to sapwood heartwood part of it. The first adults appear in Nature in March and April, and their mass flight is in May-June, there are single skater to fall. disturbed, they become immobile, for a time freeze. Fertilized females lay up to 40 eggs in flight holes progryzennye beetles after wintering at the exit from the pupa, or a rough glubokiescheli timber. It’s believed that Ebay sees a great future in this idea. Stage of development of eggs – from two to three weeks.
Live adult larva (length up to 4 mm, white, covered with yellowish hairs) immediately after hatching cutting into the wood. Protachivaya the fibers longitudinal passages, she densely scored their droppings, mixed with small bits of wood. Before pupation the larva moves to wash the wood surface, leaving not only a thin protective progryzennym (about 1 mm) layer, from which immediately same suits again deepened and pupal "crib." The pupal stage lasts about two weeks, the adult beetle lives up to one month, and the full life cycle usually takes a year, though it depends on the temperature and can vary – from 6 months to 2 years. Females lay eggs on non-lacquered or painted door frames, window sills, not plastered ceilings, beams, baseboards, etc. Among the furniture beetle often turns into a board floor, piles, beams. Of conifers species like spruce and pine, and of deciduous – linden, maple, birch, olhu.V as a prophylactic against the grinder can be used 3-percent. solution of sodium fluoride, or mixture dezinsektal the following composition (weight part): -100 turpentine, beeswax and paraffin – 5, carbolic acid – 3.
They need to thoroughly clean all parts of unpainted furniture, atakzhe her legs. Putty holes for flight prepare a special mixture (parts by weight): -15 rosin, sawdust – 5, Denatured alcohol – 30, creolin – 3 and gypsum – 25.Uchastki heavily damaged Shashel, should be treated (subject to safety regulations) solution of fluoride, sodium fluorosilicate (3 percent). Or in the BHC light oils, and then lacquered. Nevertheless, to avoid eating Shashel furniture must be processed by means of its special Shashel. A good effect is the heat treatment of damaged wood products -Warmed to a temperature of 65-70 in the dryer or electric high frequency.

Let us consider two typical situations where the interests intersect electricity supplying organizations and consumers. The main use electronic multi-tariff meter. You have built a new house (or other object that requires a separate power supply). The first thing you need to do – apply for a contract supply (if you have not already done so during the construction phase), and obtain technical conditions for the organization of metering. When choosing a meter (if not specifically mentioned in the technical specifications) should pay attention to: the availability and integrity of the seals on the body of the meter. The presence of stamps and seals in pasporte.data registration – as indicated in the passport, and on the front panel counter. The interval between the date of issue and date of installation (via) shall not exceed one god.klass accuracy – not more than 1.
Specify a number in the circle on the front panel meter and pasporte.mezhpoverochny interval, is considered the date of issue, usually at least 8 years. Indicated in pasporte.nalichie connector for remote removal dannyh.diapazon operating temperatures – may require additional heating, if the meter installed on the street. Then you invite an inspector to inspect the installation and metering of seals on the meter and the opening gun. The inspector shall prepare minutes of the examination (one copy retained by you) and seal device. Since then, no complaints (with fillings) for improper assembly or 'curves' testimony (in your favor) you submit can not, of course, if they prove that the intervention was in the scheme.
In the promotion of rapid economic development our crusher industry has accounted for half of the market and it is gradually get the international level. However, in the process of development and growth and maturity, more and more problems come out, It is such as follow. Since 2009, the mining crushing industry has been undergoing rapid development with the support of the national policy. Before the reform and opening up policy, the sand stone production was to some degree in the state of backwardness. The mode of production is very lagging behind.
There were few full sets of large crushing machinery in use. What s worse, the surrounding place were often sparsely populated and the transportation is not so god. However, with the introduction of reform and opening up policy and the rapid development of infrastructure construction, great change has taken place in the sand stone production industry at the same time. To make scientific and technological progress in gravel industry, Hongxing Mining Machinery has introduced advanced technology from home and abroad to meet the demand of the domestic market. The leading products in our company are crushing equipment, sand making machine, mobile crushing station, and grinding mill which are widely used in mining, building materials, roads, bridges, coal, chemical, metallurgy, refractoriness and other industries.
We constantly develop new product, from hydraulic jaw crusher to strong counterattack crusher, from PCL impact crusher to VIS crusher, our large crushing machinery have become catch equipment employed in the construction of highway, railway, high-rise buildings, municipal engineering, and hydroelectric dam construction and so on. To a service-oriented brand integrity, As the professional manufacturer of complete sets of machinery, like sand washer mining, Henan Hongxing is always doing the best in products and service.ore flotation equipment: Our impact crusher is featured with large particle size and average final product size. Hongxing provides different type of impact crusher used in limestone production. Our impact breaker is good in quality and after sale service. Limestone is the main material in making cement, lime and calcium carbide, and it is also essential to the flux in smelting industry limestone. After crushing and grinding, the limestone is widely used in many fields in our society. As the indispensable raw material in modern society, it is also non-renewable resources. Therefore, to efficiently use it is the basis of industrial progress and sustainable development. The physical properties of limestone is small hardness, brittleness, combined with the limestone production line multi-break less milling in limestone crushing stage to try to produce the best coexistence, so impact crusher is the most suitable for crushing equipment for limestone in the production line. Effective and practical investment. The same yield of production lines, equipment prices will have a big difference. But most of the high price of the equipment operating costs relatively low. This first purchase the equipment according to their current ability. When people have a big budget they can select a high-performance.
In Russia, the deserved success with consumers enjoy the air conditioning the Japanese company Mitsubishi. Wall air conditioning Mitsubishi is perfect for small areas conditioning facilities. In 2008, went on sale new HG series home wall air-conditioners by 22 freon: SRK20HG/SRC20HG, SRK28HG/SRC28HG, SRK40HG/SRC40HG. This wall-mounted air conditioners cooling capacity of 2 to 4 kW, which have kept excellent processing properties and high reliability of the previous series of HD, but changed the appearance of the indoor unit. The new design has a pronounced brutal nature and is more rigorous lines. Board microprocessor wall air-conditioners of the HG is protected by special silicone layer that protects against moisture and long life. In the wall air conditioners of the HG has a function of self-cleaning indoor unit evaporator, which eliminates the formation of mildew and unpleasant odors in the indoor unit. Within two hours after stopping the air conditioner automatically enabled its purification.
This feature can be disabled by the user. The structure of the HG wall air-conditioners included panel Tourmaline coated with constantly generating negative ions. Even when the air conditioner does not work, the concentration of negative ions up to 2500 – 3000 per cu. See, that is the same as in the woods near a stream or near a waterfall. At This does not make any extra energy. When running the air conditioner efficiency of the ionization process is greatly increased. In addition to the regulatory system of the air flow, allowing uniform blow all the room in the design of the HG wall air-conditioners using the principle of stabilizing the optimized corrugation, which provides a smooth air flow. This allows you to minimize noise at work air conditioner, since the interaction of air flow and fan is minimized.
In the wall air conditioners used the HG washable photocatalytic deodorizing filter. Due to be restored deodorizing filter is a reusable function. If the filter is dirty, to restore the deodorizing function should only wash the filter with water and dried in the sun. Filter keeps the air inside premises with fresh, he picks up molecules that cause odors. One component of the filter is titanium oxide. Wall air conditioning Mitsubishi Series HG – this is an excellent choice of HVAC equipment in terms of price and quality to create the ideal climate in the apartment.

Excavators Hitachi – one of the most popular on the Russian market machinery. Powerful, reliable, many years they work for the benefit of Russian builders, oil and public utilities. It is quite clear that competition is not standing still, in country flooded hundreds of cars from China and Europe. Therefore, before every potential buyer is a question whether to trust the proven brand of Japanese cars, or buy another brand? The best thing about this situation – weigh the pros and cons of excavators Hitachi, information about which service over the years accumulated a lot. So, let's face it. The main minus Hitachi has always been frail and delicate design, which suffered greatly under the pressure of local engineers, educated in the MTZ and TVEKS's.
In recent years, of course, the level of our artists has grown significantly, but in any case, Hitachi Excavators on design complexity and the presence of subtle detail is always lost to competitors. On the other hand, this delicate design not as paradoxical as it sounds amazingly reliable and if you do not interfere in her hands curves clumsy, able to work without breakdowns for many years. Other Excavators must frequently inspect and troubleshoot the various little things in between times. Time of the second. These are the current engines and hydraulics.
Here again, the point is this: the Hitachi so many models to work in a variety of conditions. And if for a particular model in the characteristics of written maximum digging depth, tonnage and power, this does not mean that the machine is designed for continuous use with such loads. The fact that the Japanese are very well-calculated characteristics of his art and, say, if the domestic excavator can pull more than is written in his passport, then the figures for the Japanese – an absolute ceiling. Therefore, if the mean operation in harsh environments, you have to buy machines with more impressive features that far exceed the maximum loads. On average, the range of from Hitachi nothing ever does not flow and does not break – just have to explain to the operator that run the entire length of the rod is fraught with breakdowns. Speaking about the pros Hitachi Power should be noted, which is almost always enough for all types of transactions. And anyway, Hitachi excavators still the most reliable, most importantly you should not skimp on quality and consumable fuels. And, of course, the most important – is that spare parts for excavators are almost always in the dealers. On the other equipment must be ordered, to suffer with the catalogs, but the Hitachi is always possible to find the most necessary. And the service in recent years has increased markedly. The only course, since prices for Hitachi excavators is much higher than other machines. But if you count the economic impact of outages, breakdowns and fuel, to buy Hitachi is much more profitable than, say, Chinese excavator.
Non-ferrous slags are different from steel slag high content of iron oxide (20-40%). Fuel slag (Zoloshlaki CHP) Zoloshlaki formed during fuel combustion at the CHP are widely used in the production of building materials. In this regard, we could not ignore this product. When burning solid fuel from its formed part of the mineral ash and slag, whose content is different for different fuels. They constitute 10-15% of brown coal, in the bituminous coals – 3-40%, anthracite – 2-30% oil shale – 50-80% fuel peat – 2-30%, wood – 0,5-1, 5% fuel oil – 0.15-0.2%. In Currently, the majority of CHP fuel is burned in pulverized state, the temperature in the combustion chamber reaches 1200 – 1600 C.
In this conglomerate of various compounds formed from the mineral part of it, stand in a dust mass. Small and light particles (size from 5 to 100 microns) contained in the ashes of up to 80-85%, are carried away from the furnace flue gas conglomerate, forming the so-called ash-entrainment. Larger particles are deposited on / under furnace slag lump of fused or vitreous mass, which is then subjected to granulation. The ratio of generated slag and ash-carryover is different, it depends on the design of the furnace at the CHP and power plant. For example, in furnaces with solid slag removal in the slag usually goes 10-20% of the fuel ash. In furnaces with liquid slag removal of slag becomes 20-40%, while in cyclone furnaces – to 85 – 90% of the fuel ash.
Vysokokaltsievye useful guide to the slag granulation. On the basis of granulated slag can obtain various kinds of high quality cement. Indecomposable of blast-furnace slag, less rich with calcium oxide, should be made slag pumice, crushed stone cast, castings and slag wool. These same products can be manufactured from slag, silica prone to decay, but then require additional costs for special technological methods to prevent the disintegration of the slag. The basic open-hearth slag quenching have increased chemical activity and, as well as blast of pellets, can be used in the production of cements. Acidic waste products are also suitable for the production of slag pumice, molten rubble and slag wool. Acid steel slag, thanks to a large number of iron oxide, manganese oxide, magnesium, silica, differ from the blast-furnace slag ability to melt at lower temperatures. Crystallized acid wastes, in particular the cupola, have high resistance to alkaline and acidic environments, as well as at high temperatures.
This allows their use as fillers in the acid-and heat-resistant concretes. Granulated slag acid open-hearth furnace and cupola of production should be used for slag Portland cement and slag other types of cement used in concrete structures exposed to aggressive influences of other aggressive environments. The main consumer of slag – cement, uses annually 20-23 million tons of granulated product. The presence of latent heat in the disordered structure of glass slag cooling abruptly gives high chemical activity, ie desire for favorable conditions, finish the formation of the structure. This latent energy of glassy slag is shown in its binding properties.
