Situation Analysis of Domestic Cemented Carbide Industry

Our country plays an important role in cemented carbide industry around the world, which is one of the main countries of raw materials and manufacture. Tungsten carbide materials have many advantages, such as high hardness, high strength, good thermal-setting, excellent wear and corrosion resistance and so on, which have been widely used in modern machining tools, wear-resistant materials, corrosion-resistant and high-temperature materials, etc, especially indispensable in tungsten carbide cutting tools. Development status and problems of cemented carbide industry in our country, mainly in three aspects: total production of large, relatively low profit margin; carbide products lack comprehensive export channels; related business technology innovation development is insufficient.

Although China in terms of production of cemented carbide is far ahead in the world, but at the margin is far lower than other developed countries. The main reason is that the domestic carbide products are mainly concentrated in the low-end products; the low degree of processing, low-tech, value-added products is not high, supporting the poor, such as the number of bars, plates and so on. While foreign enterprises focus on high-performance, high-precision and high-end CNC inserts, micro drills as well as some parts of precision instrument, so the profit is dramatically increasing. In terms of export channels, our carbide products export channels the vast majority still remain in the traditional way of wholesalers and retailers a simple intermediate channels. Each member of the channel as an independent economic entity, it will be in order to maximize their own profits, difficult to form a benefit-sharing, risk-sharing marketing model. Therefore, we should adopt multi-channel marketing management according to different carbide industries; design reasonable, flexible product pricing mechanism, keeping the right balance of sales channels; Improve information management of sales channels, improve the efficiency of distribution channels, establish direct marketing system, carbide production enterprises.

China's Self-Renovation of Tungsten Trioxide Denitration Catalyst Operating Stable

Recently, China Petroleum announced the news that after the initial 168 hours of continuous and stable operation in the 1.6 million tons of the FCC flue gas denitration unit, the self-developed catalytic cracking (FCC) flue gas SCR denitrification catalyst -- PDN-102 of the Research Institute of Petrochemical has driven success at one time. The successful test marked the PetroChina has completely owned a set of FCC flue gas denitrification technology with independent intellectual property rights. It is reported that by processing with SCR denitration apparatus containing this kind of denitration catalyst, nitrogen oxides dropped from 180 ~ 350mg / mg/m3 to 50 mg / mg/m3, escape of ammonia is less than 1.5mL, various technical indicators have reached the leading China domestic level. Furthermore, after adjusting the catalyst formulation and production process, it can also be used for dry gas boiler, process furnace, coal-fired boiler and other flue gas denitrification, with good environmental and economic benefits.

SCR denitration catalyst
 
SCR (selective catalytic reduction) because of its excellent denitration effect, stable performance, is widely used in flue gas denitration, in which the denitration catalyst is the core technology. Currently denitration catalyst widely used mainly is vanadium-based catalyst, which takes vanadium pentoxide as the main active ingredient, titanium dioxide as a carrier, tungsten trioxide (and / or molybdenum trioxide) as a catalyst promoter. Wherein tungsten trioxide due to its unique properties plays the roles of anti-sulfide, anti-sintering of carrier ect. in the catalyst. In addition, tungsten trioxide has the properties of photochromic, gas sensitive, photocatalytic and so on, and has an important position in architectural glass, toxic gas detection, photocatalyst and other industries.
 
In the past, Japan, the United States and other countries monopolized the SCR denitration catalyst production technology, China denitration catalyst is mainly outsourcing, which not only makes the high cost of procurement, but also has to pay technological packages using fee. Therefore, the development of independent intellectual property rights of FCC flue gas denitration catalyst is very urgent. This time, Chinese homegrown catalytic cracking (FCC) flue gas SCR denitrification catalyst -- PDN-102 continued to run smoothly up to 7 days, which not only gave China great encouragement of independently developed passion, but also added some contribution for China changing towards to creative country.

 

"Utopian Market" Disturbing Tungsten Market (Tungsten Heater)

tungsten heaterXu Gao, one of the China Finance 40 Forum (CF40) -Youth Economist members, chief economist of Everbright Securities, indicating that the recent China's economy is in transition, many people do not understand the current economic situation. The understanding of China's economic situation from different observers from different perspectives will be quite different. Xu Gao thinks that the biggest risk of current Chinese economy is "utopian market." Over the past few decades, in order to achieve economic growth, China did many efforts in market reform. In this respect, China has made no small achievement, which made market-oriented direction become popular.

Some people think that market-oriented reforms should be accelerated, the sooner the better. They believe that the reason why the current chinese economy is now in such complex state is that the market-oriented reforms have not yet to a certain high level. These people hold the view that the market should be opened up and let the market adjust spontaneous for overcapacity, high debt and other structural problems of chinese economic. In this process, those overcapacity, high debt tungsten enterprises will be out of the market, leaving those more promising, more healthy tungsten enterprises.

Through such "cleaning", the chinese economy will be able to get rid of a heavy burden, leaving a strong team. Xu Gao considered this idea as "utopian market", which is too idealistic and not realistic considering the complexity. In fact, history proves that such a utopian policy cannot achieve the desired results, and even bring disaster to the economy of countries. If such thinking continues to develop and expand, it will only continue to interfere the development of the tungsten market (tungsten heater element), and it cannot keep the stable economic growth for a long-term. Therefore, China should be more pragmatic to promote a progressive reform idea.

China Discovered New Photocatalytic Hydrogen Production Technology, Tungsten Trioxide Photocatalyst Expected to Develop

photocatalytic hydrogen production technologyRecently, Xiong Yujie group University of Science and Technology of China proposed a new mechanism of photocatalytic hydrogen production, which introduced the concept of coordination chemistry into organic nano-materials, and its products showed a substantial increase photocatalytic hydrogen production performance in the broad spectrum of light. In this study, the researchers took the two-dimensional nano-material of organic semiconductor as a macromolecular ligands, to use the nitrogen atom sites and introduce the platinum ions or cheaper copper ions which the content is less than thousandth to form a metal - organic semiconductor of nano coordination structure; the very small amount of nano-ligand containing cells induced the transfer and transition process of the produced charges, so that the catalyst product can carry out a photocatalytic hydrogen production in a broad spectrum of sunlight range. The development of this technology will promote the organic semiconductor material in light of the terms of hydrogen production, as well as to open up a new way of thinking for designing broad spectrum of photocatalytic material.
 
Photocatalytic water splitting hydrogen production technology is a way which can directly convert solar radiation to hydrogen energy, the great potential for development of new energy technologies, and also the problem in inner industry which is expected to be solved in recent years. Photocatalytic hydrogen production technology is mechanism which bases on the action of the semiconductor intersubband transitions to achieve the transfer of energy. Organic semiconductor materials are usually made of rich nature of carbon, hydrogen, nitrogen and other elements, which helps to reduce material costs, and in order to achieve large-scale production of the photocatalyst.
 
The band gap of tungsten trioxide is 2.4eV ~ 2.8eV, which means it can respond to a wide spectral band; at the same time, it has photocatalytic property, and belongs to a broad-spectrum light catalytic material. Experimental has found that tungsten trioxide doped with cerium (Ce) has a good activity in the hydrolysis of hydrogen light, which performance in that a certain amount of Ce can expand the tungsten trioxide response to larger visible light range, to improve the photocatalytic activity of 1.5 to 1.7 times. With the continuously research and enabled of new energy, tungsten trioxide will play a more important role in the applications in photocatalysis, desulfurization and denitration, architectural glass and other industries.

 

Britons’ Historic Poll to Leave EU Affects Gold Market

The result for British voters elected to leave the European Union(EU) has been announced today, which will have far-reaching repercussions both domestically and internationally, and immediately plunged the 28-member political and economic union into its worst crisis since it was founded.

The vote result was at times bitter and acrimonious. The Leave campaign, headed by former London Mayor Boris Johnson, took 51.9% of the vote to the 48.1% that the Remain campaign, headed by Prime Minister David Cameron. According to British Broadcasting Corporation, 72% of the electorate voted.

The result had an immediate effect on the financial markets, with the pound plunging to a 30-year low against the US dollar and the Euro, Europe’s single currency, slid 3% against the US currency. The US has for years had British membership of the EU a core part of its European policy, while the UK and China are experiencing what Cameron and President Xi labeled “a golden era” after the Britain last Oct., when deals worth 40 billion sterling were announced. Now the referendum result to leave the EU is affecting the gold market greatly, which will lead the gold price to a increasing tendency apparently. It is said that gold, as a favorable hedge investment, will be more and more popular by the investors, which will push the gold price moving up.
