To explain the basics of tungsten metal
Family in the non-ferrous metals, tungsten maintain the "high-temperature Champion" long centuries. The world's first discovery of tungsten, the Swedish chemist Club Le. He first used in 1781 tungstate acid decomposition obtained tungsten element. Then, and after a period of painstaking research, only in 1848 the system out of pure tungsten. Pure tungsten silver-white, very beautiful, the proportion 19.1t/m3. Superior performance of tungsten is chemically stable, even in heated situations, nor and hydrochloric acid, sulfuric acid works, even in aqua regia will not be dissolved. Tungsten temperature, known as the hardest natural metal melting, melting point up to 3410 ℃; hardness of tungsten metal in the top, only heated to a high temperature in order to pressure processing. Uses unique tungsten has many unique uses, such as high hardness, tungsten carbide inserts, tungsten steel can be manufactured. Tungsten steel tools, high strength than ordinary steel tools several times or even several times; tungsten steel barrel, barrel, firing in a row, even when the barrel is too hot projectile friction, can still maintain good flexibility and mechanical strength. In the metal cutting machine tools, turning tools made of tungsten steel, temperature up to 1000 ℃ still hard as before. A solution of 3% to 15% of tungsten, tungsten-chromium-cobalt alloy plating or welding the parts of the surface of ordinary steel, it is equivalent to the parts wear hard "armor", both temperature compressive strength, but also resistance to corrosion, reduces wear life can be extended several times. Because of the superior properties of tungsten steel and broad purpose, the world's annual production of tungsten, 90% are used to produce tungsten steel. Tungsten plasticity. A 1 kg weight of tungsten rod, you can pull grow about 400 km, diameter of only 1% mm filaments. Such filaments at 3000 ℃ high temperature environment, still has a certain intensity, and high light, long life, is to create a variety of light bulb filament of good material. Incandescent, tungsten, and even the world's most innovative lamps, are manufactured with tungsten. The United States has used a new type of solid fuel, the rocket gas temperature exceeds 3000 ℃. In this case, the hardest melting tungsten nozzle too overwhelming. Scientists through research, manufacturing a new type of tungsten alloy - "self-cooling permeability porous tungsten alloy of silver." When the rocket flying high in the air, this new alloy with high temperature and pressure nozzle, spray continuously sparkling flames. The nozzle surface infiltration of silver at a high temperature first evaporated while absorbing the heat of evaporation. Thus, to achieve automatic cooling purposes and to prevent excessive temperature rise, the badly baked nozzle 3000 ℃ high temperature, is still able to maintain the original character.

APT prices weaker, thinly traded
This week the domestic market of tungsten chemical APT weaker, low-cost emerging market prices for the mainstream 21.7-21.9 yuan / ton, fell slightly. It is understood that the spot market volume was light, the transaction price and more concentrated in 217,000 yuan / ton of cash, some manufacturers are still 225,000 yuan / ton offer, but it is difficult transaction or payment cycle is relatively long.
Mainly because of continued weakness in demand APT: one Minmetals and other large enterprises are currently no tungsten carbide inserts acquired on the market, the lack of this favorable support; hand end demand is sluggish, APT factory-order, strict control of raw material procurement, production control out, many manufacturers now are not the largest capacity. According to our investigations, holding the goods, it is now on the market there are also some lower-cost sources of supply, a few months ago Stockpiling, Production, but for now weak market, the business is not willing to sell, temporary fence; tungsten mine traders, affected by financial constraints, the current sourcing or procurement not too much, because money is likely to have also loaned; downstream tungsten smelting enterprises, weak end demand, tungsten smelting enterprises in strict accordance with the order production, control inventory, procurement of raw materials tungsten ore is very cautious. We expect today and tomorrow, tungsten ore market mainstream stable.

market mechanisms increasingly play a greater role.
[Tungsten Online News - Tungsten News]
Toyota R & D Center (China) Co., the responsible person recently told reporters that now for the rare earth controls and policies so strict control than in the past, the Chinese began to make greater use of market mechanisms to regulate, market mechanisms increasingly play a greater role.
The person in charge to Baotou participate in the fifth "China Baotou Rare Earth tungsten carbide inserts Forum", aimed at conduct preliminary investigations and concerns China rare earth policy developments. "From this point of view, no new, big policies, has been in continuation of last year's policy." The official said, so he was interested in "this conference a lot of people say that the release may be fixed limitations. "the person in charge hope that China's rare earth could be more stringent environmental policy," environmental policy will tighten, we think it is normal behavior, as a business, environmental standards should be, and some small businesses private dug Luancai, it should be shut down. "
During the meeting of the gap, Baotou National Rare Earth Hi-tech Zone, assistant director Ann tigers and the person in charge in the exchanges, to express a wish to Toyota in Baotou joint development of new energy vehicles, hybrid vehicles ideas. However, the official told reporters: "Toyota's hybrid cars in China awareness is not high, sales volume is not high, we now do not want to stall shop so much."
Before making Zhefan representation, Toyota and domestic battery material suppliers Hunan Corun intent signed a joint venture, the parties intended to set up a Sino-foreign equity ratio of shareholders and other joint ventures. Public information, Corun has manufacturing hybrid battery mature technology, is an international vehicle nickel-hydrogen battery is one of the major suppliers.
Public information, Keli America's four major shareholding structure as follows: Chinese shareholder is Corun (40% shareholding) and Changshu, a local venture capital firm (holding 10%), Japanese foreign shareholders of PEVE (holding 41%), Toyota China (holding 5%) and Toyota Tsusho (holding 4%). The major shareholder of PEVE for Toyota. This means that Toyota is the largest shareholder Keli America PEVE the actual controller.
National Development and Reform Commission and Ministry of Commerce jointly issued last year, "Foreign Investment Industrial Guidance Catalogue" shows that foreign investment in the energy in batteries and other key components of new energy vehicles equity ratio can not exceed 50%, of which battery is designated as "critical zero parts. "
There are rare insiders believe that Toyota chose a joint venture with Corun, ulterior motives, but through CORUN continually get more numerous, cheaper rare earths. If the investment here in Baotou Rare Earth, the degree of concern would be too high.
Although Japan and several countries to seek cooperation in earth, but in Japan through various channels into China rare earth industry chain moves, showing the dependence on Chinese rare earth in Japan is still more serious.
According to Japanese media reports, January-April 2013, Japan's rare earth imports increased by 19% compared with the same period last year, reaching 4,300 tons. Among them, the domestic rare earth 63% over the previous year increased 11 percent.
Baotou Steel Rare Earth Group Hi-Tech Co. General Manager Zhang told reporters that in the light rare earth products worldwide oversupply situation, especially rare earth lanthanum, cerium product market competition intensified, resulting in the rapid reduction of rare earth product margins small, foreign rare earth project has been in trouble. Future supply of light rare earth in China is difficult to return to the era, and China Rare Earth as a unique resource advantages, can still maintain a fairly long-term competitiveness and market discourse.

we often say that the shot blasting, shot peening.
Analysis sandblasting process has the advantage
Sandblasting is an abrasive with compressed air as the driving force to promote the work surface for processing, that is, we often say that the shot blasting, shot peening.
Sandblasting is an abrasive with compressed air as the driving force to promote the work surface for processing, that is, we often say that the shot blasting, shot peening. Because there early blasting technology, the sand is the only abrasive used, therefore, for a long time and later period of time, sand blasting has been known.
In fact blasting (shot peening) is widespread, in nature, sand, gravel and dirt in incessantly hitting the mountains, its abrasive slowly away, but this process was very slow and not easy to be aware of our Bale.
In a variety of surface preparation methods, blasting (shot blasting) the effect of the most thorough, most adaptable, widest range of applications, this is because: cleaned steel surfaces fastest and most tungsten carbide inserts; blasting can only have develop acceptable to all four kinds of cleaning performance levels; blast cleaned often difficult to clean the surface, use some special tools to clean the inner surface of the pipe, blasting the lowest cost.
Sandblasting the surface can be cleaned at the same time to obtain the desired cleanliness and the surface roughness of a certain, improve the coating adhesion on the surface of the base two effects. Even the paint is not a good time for the surface treatment is not attached to the surface of the workpiece. The role of surface preparation is to clean the surface and on the surface generation used to "lock" the required coating roughness. After blasting of the surface coating with good performance industrial coatings, the coating life can be compared to other treatment of the same quality on the rear surface of the coating was 3.5 times higher. Blasting (shot blasting) Another advantage is that the surface roughness can be determined in advance upon request, and in the clean-up process is easy to reach.

in the field of rare-earth efforts to develop wind power equipment
"Extension", that extend the industrial chain, to develop international and domestic markets for deep processing of applications and high-tech industries. The international financial crisis has revealed to us, tungsten carbide inserts, rare earth, fluoride salt chemical industry should not only focus on the international market, but also to focus on expanding domestic market. Ganzhou will seize the national implementation of the top ten industrial revitalization plan, to carry out large-scale infrastructure construction, encourage energy conservation and other opportunities to focus on the development and tungsten, rare earth associated carbide, precision molds, permanent magnet motor, energy-saving lamps and other deep-processing and application products, accelerate the Ganzhou into a national and even world-renowned permanent magnetic materials and permanent magnet motor base, carbide drill and knife base. Relying on these bases, accelerate the development of high-tech industry in Ganzhou. For example, in the field of rare-earth efforts to develop wind power equipment, new energy vehicles and other industries. At the same time, encourage enterprises to conduct direct marketing in developed countries. For example, Ganzhou Mazzoni chapter Tungsten company established in France in Europe Chapter Source Tungsten Industry Co., directly explore the international market, and achieved good results.
The international financial crisis accelerated Ganzhou tungsten, rare earth fluoride salt chemical industry provided a rare opportunity to upgrade. For example, mineral resources and products cheap to run, help Ganzhou more thorough integration of resources and reserves, and further enhance resource control and market dominance; Western countries outside the transmission technology and equipment barriers have been relaxed, is conducive to the introduction of high-tech Ganzhou technology, key equipment and high-level personnel; international number tungsten, rare earth enterprises are seizing the opportunity to accelerate the expansion of low-cost, help Ganzhou tungsten, rare earth industry into high-end industrial chain. Ganzhou should firmly grasp these opportunities, good job, "control, flow, pressure, the extension" four articles to promote tungsten, rare earth fluoride salt chemical industry, high-speed transfer to Ganzhou, Ganzhou promote resource-oriented industries to speed up transformation and upgrading. "Control", which further enhance the ability to control resources, firmly grasp attract domestic and foreign high-end industrial transfer initiative. Ganzhou Rare Earth Mining companies will accelerate the transformation and tungsten ore, fluorite ore integration, tighter control and exploitation of the total flow of resources. Take "government regulation, associations, corporate purchasing and storage, bank loans, financial support, market operation" mode, 1.8 billion yuan of bank loans in promoting the implementation of tungsten, rare earth resources strategic reserves, based on a positive declaration to establish a mining or mining development banks Fund, reserves and resources, to provide financial support industrial upgrading. Strengthen cooperation with Hunan, Baotou City, and other domestic tungsten, rare earth the main producing areas of strategic cooperation, enhance the international discourse. Encourage enterprises to "go global" development resources. Ganzhou Mazzoni chapter Tungsten Company has started the development of mineral resources in Madagascar.

from the original type U to UV
Also specifically pointed out that because of the hard tungsten carbide coating, in the same corrugated stare blankly, tungsten carbide inserts carbide corrugated roll can do much steeper of the corrugated type, that is, from the original type U to UV, into a "V". In short is to reduce stare blankly tip arc, in corrugated core can significantly reduce the shrinkage rate of paper. To general AB double tile board, there were two core paper, reduced by 3% per side, each square board there will be a 6% reduction of profit margins. Machinery manufacturers, of course, they can provide us with less corrugated cardboard-box factory choice type of shrinkage, but buyers must consider to be clear about, because of the high different stare blankly, going a while at distance, sharp radian and different high, for flat crush strength of paperboard, molybdenum plating pressure strength and puncture strength all have different effect, must carefully choose a good equipment suppliers, joint of this plant commonly used corrugated base paper, consultation with the engineer, choose the most beneficial type corrugated tooth. Must avoid one-sided pursuit of the lowest corrugated shrinkage, silks is pointed the tooth shape, available and minimum corrugated core in the paper, in the process of forming silks, paper not molding, manufacturing medium pressure, is not worth the cost or consequences to improve core paper grades. Purchase price, our factory import tungsten carbide is less than $40000, 1600 x 305 is 2 ~ 3 times the price of domestic companies. But in the whole life to analysis: imported tungsten carbide corrugated roll is 35 million meters long, and domestic corrugated roll life span is only 8 million meters long, then a pair of imported tiles add a repair of the cost of the roller, is equal to two pairs of domestic corrugated roller work hardening time repair costs. Basically the same in price, but for the cardboard quality, imported tungsten carbide tile roll on corrugated stare blankly is high, the quality can maintain unity, and the domestic tile roll on new purchases or a new mill when can have the good quality of cardboard, but has the certain process is accelerated, corrugated stared blankly on the high side, wasted core paper shrinkage rate, increase the cost. Domestic corrugated roller run after 2 ~ 4 month tile roll wear, corrugated will become low, cardboard quality drop, influences the business growth. "

Terms of its total electroplating wastewater, such as paper, printing, chemicals, pesticides and other small water pollution narrow. However, due to electroplating factory points widely distributed, highly toxic substances contained in the wastewater of many kinds, its harmfulness is great. Compliance electroplating wastewater untreated into rivers, ponds, into the ground, not only will harm the environment and can contaminate drinking water and industrial water. Chromium electroplating wastewater containing zinc, copper, cadmium, lead, nickel and other heavy metals and acid, alkali cyanide and other toxic debris great. Some also belong to the highly toxic carcinogenic and teratogenic substances must be handled carefully in order to avoid harm to people.
motorcycle plating parts care Raiders
A Molybdenum plate usually consists of thousands of large and small parts, plating parts is one of the important part. Motorcycle plating by plating metal plating base material can be divided into parts and plastic plating two kinds, such as the handlebars, fenders, rims, exhaust pipes, etc., are metal-plated base member; while scooters shell, instrument, trademark, logo belongs plastic plated vehicle base member. If the motorcycle plating intact the vehicle will look brilliant. Conversely, if the plating for rust, scratches, dents, then the vehicle is even ugly, and further affect the rider's image. Luxury imports, as some large displacement motorcycles, such as tungsten carbide inserts exhaust pipe corrosion, the car will be trouble (because these parts are very difficult to buy).
A plating layer classification and characteristics
Electroplating layer classification and characteristics: the plating layer can be divided by the use of a protective function, decorative and functional three categories.
1, the protective coating: As the name implies, this coating is used to prevent the corrosion products and parts, the motorcycle production process usually galvanized to protect the steel main parts.
2, protective - decorative coating: This coating in motorcycle production process most widely used manufacturing processes complex than the protective coating, at least two or more plated, and some more. If the motorcycle fenders, rims, croissants handlebars, exhaust pipes, etc.; This coating looks good apart from outside, but also play the role of preventing corrosion of the main parts.
3, the functional coating: This coating is usually applied to shaft parts, engine cylinder and piston ring friction surfaces, in general, chrome ways to increase the wear resistance of the main parts.
4, other coating: the production of tires, in order to increase the pressing between the wire and the rubber of the adhesive, the general approach is copper zinc alloy on the wire. Depending on the application, different metal plating is commonly used metals are zinc, copper, silver, lead, chromium, nickel, black chrome, black nickel.
Second, plating parts protection measures
Most corrosive plating solution, the organic acid is stable to long-term luster. However, the following situations will corrode the plating layer, need to pay attention and to take measures to protect it.
1, should prevent salt, hydrochloric acid, bittern and other substances. Because the coating is easy to dissolve in the above-mentioned substances, so avoid with 84 disinfectant, bleach, toilet Qing substances.
2, the motorcycle should not be stored in a gas, pellet heaters, soot BBQ place. This is because the carbon monoxide (CO) generated gray-black mesh coating will crack and corrosion.
Electroplating wastewater treatment process and the principles of heavy metal removal
Principle heavy metal removal
Heavy metal ion removal agent generally over a wide pH range (pH3-12) within the application range of this PH can actually use the heavy metal ion removal agent treatment, and can achieve better results. But does not adjust PH value reacquisition agent tungsten carbide inserts directly in the cost is not economical, the pH should generally be adjusted to a certain range, a portion of the heavy metal ions in the form of a hydroxide precipitate, thereby reducing the heavy metal ion removal agent usage, reducing processing costs. Table 1 shows some of the precipitated metal hydroxide optimum pH range.
Metal ions Fe3 + Al3 + Cr3 + Cu2 + Zn2 + Sn2 + Ni2 + Pb2 + Cd2 + Mn2 +
The optimum pH precipitation 6-125.5-88-9> 89-105-8> 9.59-9.5> 10.510-14
Alkali will re-dissolve the pH> 8.5> 9> 10.5> 9.5
Cr (VI), should be restored by means of a reducing agent, so as to be reduced to trivalent chromium, and then be removed by the above method.
Finally, we pass a certain amount of coagulant, so heavy precipitate formed settle down in the settling tank to reduce the water of the SS, resorted to water becomes clear and transparent.
(Three) Process Features and Benefits
