transparent and frosted bulb two kinds of different specifications

In 1959 it was discovered after the halogen cycle principle produce halogen, it gives thermal radiation source has injected new vitality, this kind of light, small size, light maintenance rate of 95% or more, the luminous efficiency and lifetime were significantly better than incandescent lamps. In recent years, it has produced can be directly applied to the grid voltage 220V or 110V halogen lamps, and its size can be as small ?14 × 54mm, with a filament stability and shock resistance are excellent characteristics, transparent and frosted bulb two kinds of different specifications, internal fuse in line with IEC A32-2 standard, G9 type lamp is easy to join, its main technical parameters are shown in Table 1 below. In recent years has launched a variety of energy-saving halogen lamps new varieties, such as on the use of quartz foam shell coated TiO2 / SiO2 infrared reflective layer technology (IRC) made JD-and JDR Halogen type novel, by allowing visible light Tungsten eletrode, and the process of the infrared reflecting back to the filament, the lamp luminous efficacy of 30% -45% increase, the life of 3000h. Since halogen chromogenic particularly good, but small volume and easy decoration, so much people still favored and widely used.

Halogen tube is preferable to the illuminance higher, better color rendering or require dimming places, such as stadiums, town halls, banquet halls. The color temperature is particularly suitable for color television studio lighting. Because of its higher operating temperature, suitable for dusty, flammable, explosive, corrosive environment, as well as vibration places. Halogen quartz condenser for shooting movies, television and stage lighting or back in the spotlight with light fixtures.

therefore also called interstitial (or insert) compound.

Mainly for the production of tungsten carbide material bowl. Tungsten eletrode carbide, the carbon atoms in the metal lattice embedded tungsten gap, does not destroy the original metal lattice, forming an interstitial solid solution, therefore also called interstitial (or insert) compound. Of tungsten carbide and carbon can be heated to high temperatures to obtain a mixture, the presence of hydrogen and hydrocarbons can accelerate the reaction. If the oxygen-containing tungsten compound prepared, the final product must be 1500 ℃ vacuum treatment to remove oxides of carbon. Tungsten carbide suitable for machining at high temperatures, can produce cutting tools, materials of construction furnace, jet engine, gas turbine nozzles.

Tungsten metal and carbon black as raw materials bowl, mix dubbed by a certain percentage, the mixed material was charged into the graphite boat, placed in carbon tube furnace or a sense of high frequency electric furnace at a temperature carbonization, and then after milling, screening that was carbide powder.

tungsten carbide

For many years, the quality of the corrugated roller cartons has been plagued by domestic enterprises. In December 2001, Shanghai everbright corrugated packaging exhibition, Germany fly wire (Friese) to domestic containing cobalt and tungsten carbide corrugated roll are introduced, and the first to bring home a cardboard-box factory and was the feeling that find everything new and fresh; International corrugated exhibition in Paris in June 2002, during the meeting, internationally renowned corrugated roller Tungsten eletrode launched all kinds of high quality corrugated roll, including tungsten carbide corrugated roll clueless; In late 2002, the domestic several considerable size of the cartons enterprises to start importing tungsten carbide roller; Until February this year, the Shanghai big pine (corrugated roller) industrial co., LTD formally will be tungsten carbide corrugated roll to market, become the first domestic a tungsten carbide manufacturer. Tungsten carbide corrugated roll in the spring breeze can blow through China, see our understanding to the tungsten carbide rollers in the domestic application situation.
By roughly understanding, learned that the tungsten carbide corrugated roll, long life, high precision, after-sales service is also good, so bought a pair of Germany in 2002 fly wire and tungsten carbide. Overall effect, life can be, the only think the price is higher, haining pavilion creek packaging co., LTD., says Mr Zhuo the tungsten carbide roller is equivalent to two pairs of domestic ordinary corrugated roller price. 1 year after the purchase made a grinding. Due to imported from abroad, grinding must be sent to abroad for, not only the cost is higher, and the time is long, become a purchase the tungsten carbide corrugated roll only regret. If tungsten carbide corrugated roll have ability to repair, after-sales service, the overall price down some, prospects should be good.

production technology and technology of tungsten copper alloy

Tungsten eletrode mining lack of total amount control, production is still serious. Advantage for the protection and rational utilization of tungsten mineral resources, starting in 2002, the state shall practise a planned according to the protective exploitation of specified minerals mining rules, the comprehensive research resource reserves, existing in exploration right or mining right Settings and trend at home and abroad market demand conditions, the tungsten mining total amount control Molybdenum tube, and gradually to increase resources tax and stricter mining system and a series of measures, but these measures to carry out the effect is not ideal, tungsten concentrate yield levels every year. Excessive amounts of the main reason, it is a standard part mainly from local collective and private small mines, the mine regardless of the index limits, blind expansion; Second is the name of the other minerals mining tungsten; Three is in big mines around still exist some phenomenon of illegal mining.
Resource comprehensive utilization level needs to be improved. Tungsten after nearly a century of mining in our country, at present, the most black tungsten resources in China has almost dried up. Mining enterprises to reduce costs, there is a rich abandon poor phenomenon, individual companies or even back to the manual, half manual work, resource recovery rate is low. Enterprises, especially small tungsten mountain is basically all the individual owners lease contract operation, low technical quality, the pursuit of short-term interests, mining rich abandon poor, difficult to pick by master abandon time, easy to abandon the predatory exploitation of phenomenon is common, waste resource loss is great, beneficiation process simple, low efficiency, adopted by the recovery of tungsten concentrate, only accompanying the rest of the most valuable metal is not recycled, not only the recovery rate of tungsten is extremely low, many associated metal elements is wasted. Individual companies even not built or built after not using tailings, discarding the backfilling of tungsten and the grade of the valuable metals are high, with associated also did not get reasonable utilization of resources, low comprehensive utilization of resources. Abandonment of backfilling materials not only caused the waste of resources, also caused many environmental problems.
Mining science and technology input, less acquisition technology and equipment level is not high. Lack of tungsten dressing technology research input, loss of many professional and technical personnel, technical level is unbalanced development, mining of innovation ability is not strong. Tungsten beneficiation research is less, the basis of new separation equipment research and development also largely stalled, part of the refractory ore beneficiation technology is still no new breakthroughs, such as the weathering scheelite recovery has struggled to get good results. Hard to choose black and white tungsten mixed ore dressing technology is not perfect, still has larger ascension space in ore dressing indexes. Exchange of experience and tungsten mines abroad processing technology also very few. For tungsten beneficiation dressing plant, foreign technology understand less, not to mention the introduction of advanced technology absorption.

The advantage of TZM molybdenum alloy

 TZM Tungsten eletrode strength at high temperature than other molybdenum materials, high strength, wear better, molybdenum alloys in the crowd. TZM molybdenum alloy recrystallization temperature than pure molybdenum high 300-400 ℃. TZM molybdenum alloy is widely used in hot runner, thermoforming molds and other fields
