Steeper rise of the curves at the beginning of heavy gases due to lower heat losses. Increasing power density by increasing the current causes a drop light output. Check out Adroll Marketing Platform for additional information. For small power densities with heavy inert gas filling provides higher light output, but with increasing specific power advantage is shifting towards the lighter gases. For tubes 38 mm in diameter at specific loads, more than 2.5 times higher than optimal, filling neon gives a higher light output than filled with argon. Reduced pressure filling gas increases light output. Thus, when creating a lamp with a 4-5-fold overloaded compared to the standard replacement of neon and argon pressure drop to 200-267 Pa (1.5-2 mm Hg.
Art.) can give gain initial light output by 25-50% compared with a similar bulb filled with argon. Another method of solving the problem of choosing the optimal conditions for powerful filling tubes was proposed by IM Veselnitskim. Experimentally and theoretically, it was shown that at low pressure inert gas T Rez goes through a maximum, whose position with increasing PiCT shifted to lower pressures. Such a pattern most clearly marked for the heavy gas filling and large-diameter tubes (38.54 mm). On this basis it was suggested to fill the lamps with high PICT heavy inert gases (Ar, Kr) to much lower pressures than taken, lying close to the maximum g RSZ from ri.g. For example, the maximum iiPe3 high PiCT and 38-54 mm diameter tubes filled with argon is obtained for up to 13.3 Pa (0.1 mmHg.
Cent.). In this section of this category with PiCT = l, 6 W / cm is the standard Chgez fluorescent lamps with 80 W P = 0.5 W / cm. The initial light output by approximately 10-15% higher (depending on power) than when filled with neon to a pressure of 270 Pa (2 mmHg. Cent.). However, there are serious problems with the manufacture and working electrodes.
Plastics are materials which are produced on the basis of natural and synthetic polymers and recyclable items in plastic deformation methods. To rank as polymers, natural and artificial resin. Resins produced from the products of coal, oil and other raw materials. Plastics are composed of: binders, fillers, plasticizers, dyes and other additives. Resin is the basis of plastics in addition they determine their basic qualities. In the production of polymers using fillers to make the plastic strength, hardness and other qualities. Fillers can be organic or inorganic.
Are organic wood flour, cotton fringes. As inorganic fillers used asbestos, graphite. Dyes perekrashyvayut plastic mass as well as to its basis in a specific color. Used as mineral pigments, and organic. The composition of plastics often contain additives which affect the characteristics of plastics, such as stabilizers – substances that prevent the decomposition of polypropylene in the course of its processing and under the influence of atmospheric conditions, high temperatures and other effects. Plastics are reasonably lower density compared with metals, so the strength of some plastics is approaching strength of the metal.
Tensile strength fiberglass is not much less than steel. Replacing metal with plastics reduces the weight and metal products. Plastics have a fairly high plasticity, because of this complexity of the production of complex parts on the basis of plastics is much less labor intensity of production of products from other materials. But the plastic qualities of plastics are shown not the same. Some of them during the solidification lose their flexibility, they can not be softened again by heating. Polyvinyl chloride vinyl plastic for example, you can soften again and apply again.
Given that mixed with the dough entering the auger chamber has a temperature of 30-40 C, we can say that the cooling water temperature must not fall below 30 C and the optimum water temperature is 36-38 C. The corresponding Such a cooling water temperature reduces the mechanical degradation of gluten. Another significant factor influencing the degree of mechanical destruction – finish of the surfaces of the screw and the working chamber, the proper cutting grooves on the inner surface of the working chamber. These surfaces must be polished to reduce the degree of resistance to sliding test on these surfaces. When all these conditions, the mechanical destruction of gluten is minimal, as Pump it vozmozhno.Vakuumirovanie test test were used for the first time with the introduction of screw pasta presses, in which compaction pressure does not exceed 60kgs/sm , but this was not enough for dense and firm pasta.
Ghost 22 584 states that the hoist – lifting device is a pendant with a manual or motorized. Today, every service station, warehouse and production plant are used in their daily work hand hoist. Depending on preferences, working conditions and the type used by different models: gear chain hoists, lever hoists, wire rope hoists and electric hoists, etc. are allocated (elektrotali) and manual hoists. Electric hoists Electric hoists can be divided into two types – chain and rope. The choice of lifting mechanism depends on the weight of cargo that must move and intensity of use. Tali electric cable today perhaps the most popular in the world of lifting equipment used in companies with high rate of work. In Russia, the technical requirements for cable-talyam stated in GOST 22 584.
Load capacity wire rope hoists are sometimes higher than 100 tons. Payload another variety of electric hoist chain, is no more than 5 tons. The rope used in the first model, a more reliable, easy and cheap traction element than the chain, in which there is always a weak link. That quality makes the traction element model hoists so different in design. Average lifting speed chain hoists within 2 …
5 m / min, and cable – 5 … 12 m / min. Electric hoists are undemanding in operation and are suitable for work at temperatures from -63 to +40 degrees Celsius. Chain hoist is used as auxiliary structures for cantilever-cranes. Elektrotali rope used too and the overhead crane for lifting and transport medium and heavy loads, because the duty on wire rope hoists chain excel. The basis of the assembly in an electric hoist – a block mechanism sotoyaschy of motor, reducer, drum or sprockets, brakes, hooks and lifting element. Drum are only in electric cable talyah, and the star – only to chain elektrotelferah. Tal is equipped with a portable control unit, which enables comfortable control mechanism. Available storage equipment of two types – mobile and stationary. Portable models are moved in the vertical and the horizontal plane. Hand Blocks Tal manual for those companies and industries that have no need for lifting at high altitude and in the fast pace of work. They can be hung on a stationary or mobile cat when there is a need horizontal movement of the loads. Tali ruchnyeshesterennye and lever can primenyatsyadlya lifting and outdoors, and indoors, including in a limited area (trenches, wells). Capacity hoist hand is usually up to 10 tons, in special cases – up to 50 tons (such arrangements are made to order). In the manual gear talyah as heavy-lift element applies round-chain 3 m long or more. In the lifting of the load lever talyah performed by acting on a lever mounted on the hoist. Carrying capacity offered hoists up to 3 tons, lifting height of 1.5 m.
Quite often, the happy future owners of the houses asking the same question: "Are you from the woods? Not because of the Chernobyl accident under? "Indeed, if we follow the logic, the best wood – wood is the northern, in exactly Chernihiv, Zhitamirskoy, Kyiv region, the most affected areas of our country from the Chernobyl accident. However, despite this, the wood from these areas trains exported to EU countries, where Believe me, the issue of environmental friendliness and radiology paid very much attention. This forest meets the requirements of the EU countries, so it is clean and the houses built out of it, suitable for living. Each Normal Organization will provide the customer a phytosanitary certificate and radiology at the forest from which made its timber (another way to distinguish between "Sharashkina office" of the actual construction firm). Data documents can be formally obtained from the forestry enterprises engaged in logging and cooperate with legitimate organizations.
Without them, none of the log does not cross the border of our state. At worst, I recommend simply purchase household dosimeter and walk with him near the plant ready to export their logs to your building site. I can assure you right away – no increased background you will not find a trace, shattering another ridiculous The myth that an environmentally friendly wood can be only in the Carpathians, Karelia and Siberia. The most common types of wood used for construction of wooden houses in Ukraine – it is pine and Carpathian Smereka. Rarely used spruce, Russian larch and cedar. Very rarely – oak. Take the two most common species (pine and Smereka) and try to compare them to physical and mechanical properties: 1.
Indicators of average moisture content of wood freshly cut pine – 88%, Smereka – 91% 2. Density at 12% moisture: pine – 500 kg / cubic meter, Smereka – 445 kg / cubic meter, 3. Density in a completely dry pine – 470 kg / cubic meter, Smereka – 420 kg / cubic meter, 4. The coefficient of volumetric shrinkage: Pine – 0.44% Smereka – 0.43%. 5. The coefficient of radial shrinkage: Pine – 0.17% Smereka – 0.16%. 6. The coefficient of tangential shrinkage: Pine – 0.28% Smereka – 0.28%. 7. Coefficient of volumetric swelling pine – 0.51% Smereka – 0.50%. 8. The coefficient of radial swelling: Pine – 0.18% Smereka – 0.17%. 9. Coefficient of tangential swelling of pine – 0.31% Smereka – 0.31%. As can be seen from the data, the coefficients of the properties of shrinkage and swelling are almost identical. The only thing what wins pine – that wood density – 11% higher than the density-density Smereka. But the house of Smereka slightly warmer home from pine, according to the organization, working exclusively with this material (due to the looseness of wood). The greatest density of all types of wood used in wooden house construction, is English oak – 690 kg / m, beech – 670 kg / m and larch – 660 kg / cubic meters, the smallest – Siberian fir – 375 kg / m and cedar – 435 kg / cubic meter.
