Tungsten Mining Enterprises’ Positive Action Make Tungsten Market Worth Expecting

On June 7, the domestic mainstream large-scale tungsten mining enterprises are going to gather in Chaozhou to held the third meeting. The eight mining enterprises participated in the meetings have 27 affiliated mines, production of tungsten concentrate is more than 50% of total domestic production, so these eight tungsten mining enterprises are accustomed to be called "Eight tungsten enterprises" in the market. This is the third meetings of eight tungsten enterprises since November, 2015 and February, 2016.
 
Counting the two previous gatherings of tungsten enterprises, it’s no doubt that played an important role in turning the situation around, especially the large enterprises meeting in Xiamen Tungsten in November 15. Tungsten market experienced the historical low price, the mainstream tungsten enterprises had heavy losses, the strategic raw materials were facing the loss with low-cost, the responsible corporate has affirmative action to be a solidarity to maintain market. The second meeting of tungsten enterprises was held in Guangzhou on February 2016. Market prices hiking got sick, the large enterprises maintained market actively, so the price hiking was reasonable.
 
The third meeting will be held in Chaozhou on June 7. With the background of the fall of tungsten concentrates price, the timely convening of this meeting is of great significance for the market. Comprehensively, the current meeting may save the current weakness of the market in time, the market will be greatly boosted, leading tungsten market a healthy development. As for the price of tungsten products with the most concerned in the market, it’s thought that the basic price will stop falling, but tit’s not likely to increase greatly, mainly because of the less demand of late summer market, and the price being too high will bring high-priced stock refluxing into market. So it’s expected that the later price based on small price fluctuations than the current price.

Sky-High Green Ticket Reproduced, Tungsten Trioxide Denitration Catalyst Boosts Air Purification

June 1st in the morning, Shanghai Environmental Protection Bureau said it would write a ten million Yuan of green ticket to a company; and, it was revealed that Shanghai is revising the new environmental regulations, proposed individual fines from 200,000 Yuan increased to 1 million. This may be another 10 million Yuan level green ticket since last year after the Qinhuangdao City Environmental Protection Bureau of the States (Qinhuangdao) Co., Ltd. Sewage Treatment out of nearly 13 million of ticket.

Some netizens commented: "Well done, if they had known today, why didn’t it take this ten million to invest in SCR denitration desulfurization project which can also contribute to improve our living environment." Denitration catalyst is the core of SCR technology, the current widespread used is based on tungsten trioxide (or molybdenum trioxide) and vanadium pentoxide as the main active material, the titanium oxide as a carrier, and loading of other related species. Tungsten trioxide can improve the anti-sulfidation of the catalyst, and to enhance the anti-weld ability of the carrier. By the way, the nano-tungsten trioxide will exhibit better performance with its larger surface area.
 
It is reported that, more than 20 units of the plants have been completed desulfurization and denitrification transformation in Shanghai, this year, more than 1,400 factories also identified to carry out VOCs transformation; in addition, tens of thousands of the old cars would be eliminated. Exhaust gas thermal power plant is one of the main sources of NOx and other pollutants, the using of SCR project using tungsten trioxide denitration catalyst to governance, is now widely recognized as the most effective way of NOx removal; at the same time, the elimination of old cars, while vigorously implement the vehicles which installed tail gas treatment unit (such as tungsten trioxide with SCR denitration catalyst), thus, the pressure on the environment will possible to greatly reduced. 
 
I believe if everyone pay attention to the environment protection issues, what smog, water pollution ect., will be nowhere to hide, and sky-high green ticket will no longer appear.

Tungsten Copper Liner and Terminal Sensitive Projectile

Recently, famous Chinese scientist Yang Shaoqing ammunition invited in the CCTV program for the audience of a presentation mysterious "Tank Terminator" – terminal sensitive projectile. Terminal sensitive projectile is also called as sensor detonated ammunition, which is a new kind of anti-armor weapon developed in 1970s. It can detect the presence of a target terminal ballistics, and can make warhead explosion direction towards the goal, mainly for autonomous attack armored vehicles top armor, it has long distance, high hit rate, good penetration effect in the 21st century information battlefield.

TSP is composed of major shells and propellant charge composition. Major missile includes elastomers, time fuze, projectile structure, end-sensitized bullets. And the end-sensitized bullet consists of save spin and steady deceleration scanning systems, sensor systems, central controller, advanced warhead, power, etc. Wherein the central controller is equivalent sensitivity projectile brain centers, its main role is to drive control, data acquisition, signal conversion and fire decision-making. But the final damage caused to the target is the EFP warhead. EFP- Explosively-Formed Projectile, heat liner formed by long thin jet of metal armor, except that after the EFP warhead explosion, shaped charge liner crushed deformed, forming a stout and dense penetrator pills, which speeds up about 2000 m/s, less than the shaped charge jet velocity (8000 m/s), the jet penetration is deeper.

TSP self-forging fragment warhead usually uses heavy metals to fabricate metal liner, which requires good ductility, high density and a reasonable price. From the properties, gold and rhenium is appropriate, but they cost a lot; although depleted uranium armor can meet the requirements, it still radioactive and many countries oppose to use. So copper used widely in liner in early days. Today, tantalum and tungsten copper liner is two main types of liner materials. Tungsten copper shaped charge jet of tungsten have a higher head speed at the time of penetrating armor can shorten the time through, thereby facilitating against reactive armor. But its crisp texture and poor powder adhesion, good ductility copper added contribute to its shape, so the stability of the jet improved and prevent from breaking.

Tungsten Trioxide Photocatalyst Disarming Intruder from Inside

Occupants of new homes may be living dangerously, albeit unwittingly, with harmful air seeping out of their interior decor or furniture. But, there is some way to solve this problem, the tungsten trioxide photocatalyst, which us the substance that cause a chemical reaction on exposure to light, utilizing photons in the process to break up noxious gas, such as formaldehyde, benzene and TVOC, into H2O and CO2.

tungsten trioxide photocatalyst disarm intruder
 
Moving into a new home could unwittingly invite an unwelcome "intruder" - noxious air seeping from the interior dcor or furniture that can hurt you as much as the city's notorious smog. A director of house environment techniques has once said people with a penchant for grand or complicated interior decoration are compounding the smog problem as the materials used could emit formaldehyde and TVOCs (total volatile organic compounds) that are harmful to health and can potentially cause cancer.
 
Recently, a photocatalyst developed into a liquid product has been invented, which can be sprayed onto walls, furniture, children's toys or clothes, thus to help clean up the air and kill the bacteria around them.
 
Besides the pollution from decoration materials, a tungsten trioxide photocatalyst can also deal with smog pollution and are thought to be an even better alternative to air cleansers. Moreover, photocatalysts can also be used to purify the air in cars. Last year, more than 23.85 million new cars were registered in China which is the highest ever recorded according to the Traffic Management Bureau of the Public Security Ministry. A survey has shown that about 90 percent of 200 cars tested were found to have an interior air quality problem due to excessive formaldehyde and benzene. However, with the development of photocatalyst, this issue will not exist anymore.
 
By the way, another advantage of tungsten trioxide photocatalyst is that, theoretically speaking, as a catalyst it will not be consumed, so its effect should be permanent.
