Styrofoam Solution

The data presented shows in a single experiment can get a range of densities mentioned solutions depending on the concentration. With increasing concentration of the solution density increases significantly, being in the range of densities gum turpentine and resin polystyrene, reaching 40% for solutions concentration of 0.957 g/cm3 density polystyrene 1.05 g/cm3. The amount of waste expanded polystyrene (Vpp, cm3) to obtain the appropriate concentration of solutions obtained by dividing the sample of the waste in the waste density polystyrene (0.02 g/cm3). The amount of waste polystyrene foam table. Several characteristics of the processes of waste polystyrene into solutions of gum turpentine, depending on their concentration. p / n Name of the characteristics of gum turpentine concentration,% 10 20 30 40 1.

The most interesting from the perspective of a high degree of compaction of waste polystyrene and their use in casting a 40% solution. He has sufficient fluidity to Dosage and smeseprigotovleniya sand molding and core mixtures in conventional mixers operating mode without changing their operation. The authors of this paper suggested formulations and methods of cooking such mixtures with very high strength characteristics comparable to much (an order of magnitude) more expensive resin binders 6.

Crucible Induction Melting Electric

Induction crucible furnace designed for melting and overheating of steel and cast iron. Possible melting of nonferrous metals (bronze, brass, aluminum) and their alloys in a graphite crucible. It is used in foundries, steel factories, workshops precision casting and repair shops engineering plants to produce steel castings of high quality. Induction heating – heating bodies in an electromagnetic field due to the heat of the vortex electric currents flowing through the heated body and excited in him due to the phenomenon of electromagnetic induction. When the current in the heated product is called induced or induced current. Induction units called electrothermal devices for induction heating or melting metals. Induction furnace, induction melting furnace – electrothermal equipment for melting materials with using induction heating.

Induction furnace operates on the principle of the transformer, whose primary winding is water-cooled coil, secondary, and at the same time load – located in the crucible of metal. Heating and melting of the metal takes place due to the currents flowing in it, which is caused by the electromagnetic field generated by the inductor. Electric consists of the smelting unit and equipment set. Melting unit is designed in a supporting frame consisting of two racks welded construction site "setting inductor" and the two hydraulic rams. Inductor consists of two sections, each of which a multiturn coil water-cooled, made of copper rectangular tube. Supply to the inductor power and water by using water-cooled flexible cables connected to it sequentially.

Hydraulic rams provide slope to drain metal furnace at an angle of 95 for 20 seconds. Managing tilt the furnace by an electric control valve, control panel, the slope of the furnace installed on site. Induction furnace is fed from the network through thyristor frequency converter TPCH, which is designed to convert three-phase industrial frequency AC high frequency. The main advantage of thyristor Electrically before is because of the lack of no-load losses reduced potreblaemaya power, increased efficiency, lower operating costs. Supply voltage converter comes from the transformer. Electric power is controlled by changing the voltage at the output of the converter and automatic frequency control in the smelting process. On front of the transducer placed controls, security alarm and control of the converter. In the control cabinet and authorities are signaling the remote control thyristor converter and control equipment and alarm systems. The cabinet mounted cooling water monitoring sensors and alarm systems cooling electric furnaces and condensers. Status of the lining of the crucible is monitored visually and by periodic measurements of the inner diameter of the crucible. Control over the work by using electric instruments and controls, located on the cabinet front panel controls and alarm systems. Main advantages of induction melting furnaces ITPE: In the manufacture of ovens used new clean and high quality materials, asbestos is not used. More robust components – Czech and German mid-capacitors. In furnaces used reliable thyristor frequency converters a new generation of automatic frequency control during melting. High power of fusion. Calculated and optimized selected inductance of inductors and trunk capacity of capacitor banks, the losses in the furnace circuit is minimized, resulting in achieved: higher productivity, greater efficiency in energy consumption, higher efficiency furnaces. In the production of electric current applied advanced technology. Rods of hydraulic cylinders are protected from the metal spray. Significantly increased and reliable operation of the furnace. Increased safety of operation of furnaces. In the design and manufacture of products focused on improving the effectiveness of protection equipment, and accordingly it standards of safety.

JVC Professional

Company JVC Professional introduced the analog video camera TK-C9510E day-night", which transmit the image tsvetokorrektnoe in adverse lighting conditions. New items are used 1/2inch CCD-matrix, 14-bit DSP processor is the latest generation to form a video signal with a resolution of 580 TVL at illuminations to 0.025 / 0.003 lux. To be effective in a particular video object unit supports technology Super LoLux, ExDR Plus, noise and inverter 3DNR bright illumination HLI, as well as a comprehensive range of quality settings and 8 preset modes Scene Memory, including fog. In addition, TK-C9510E is equipped with a x2 digital zoom, motion detection and alarm input and uses the remote configuration protocol telemetry JVC and Pelco P / D. The high performance obtained with the TK-C9510E provides images 1/2-inch CCD-matrix of interlaced and 14-bit DSP processor generation digital video processing 2010 With such filling could improve the performance of the camcorder, the resolution to 580 TVL, signal to noise ratio to 52 dB and implement a series of new technologies to improve video quality. In addition, the new camcorder has a Mechanical IR filter for shooting in the "day-night" and transmits color / black and white image with a minimum illumination of 0.05 / 0.006 lux, and in the accumulation mode frames Sense-Up – to 0,025 / 0.003 lux. New cameras will work effectively for objects with complex lighting conditions, such as when they are installed in front of window frames, doors and other sources of bright natural / artificial ambient light.

Fusarium Planted

Given the large areas of FG 'Adelaide' begins to plant potatoes with early-stage and ends at the optimum. The farm is used protectant "Rovral Akvaflo" to protect potatoes from: Rhizoctonia, Fusarium, superficial necrosis, dry and wet rot. As an alternative to fungicide use "Maxim". At the time of planting potatoes is possible to use drugs "Prestige," "Masterpiece," "Tyrant," have fungicidal and insecticidal action. Tubers infected with highly mutually sort, so preparations, applied to the surface of tubers, is a kind of protective shield against harmful organisms. Planting crops are potato GRIMME GL 34 T, which has standard equipment. Potato trailers, 4 rows, 75 cm row spacing, 4 support the wheel, 3-ton capacity hopper parallelogram suspension openers, tractor capacity of more than 80 liters ..

The farm potatoes are planted in wide method followed by the formation of ridges, ie, in the process of landing is not formed a high crest, and subsequently formed the crest of the correct height. Tubers are planted at a depth of 6-8 cm from the top of the ridge, followed podgrebaniem soil. It is essential that the tubers were planted at the same level doposadochnoy the soil surface. It should be also take into account the fraction of the tubers are planted in large fractions of 2-3 cm deeper than the smaller ones. When planting the tubers too deep of a new crop are located deep, which makes mechanical harvesting. Properly conducted planting of potatoes, and predicts the amount of harvest and ripening time, as well as provide a convenient and quick cleaning. As a result, we have a beautiful, uniform potatoes, without mechanical damage and disease who gladly offer to sell yourself and eat. More information on FH "Adelaide
