PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.

“In 2009, foreign trade investigations initiated by China Chemicals' export products reached 20, involving an amount of up to 2.286 billion U.S. dollars. By the end of May this year, 4 new cases were filed.†Zhao Jungui held on the 16th, 2010 (the 10th "China International Chemical Industry Exhibition Press Conference" told reporters.
Zhao Jungui pointed out that China has become the world’s second largest producer and consumer of petrochemical products after the United States, but its international discourse does not match the soft power and hard power.
"The ability of Chinese petrochemical companies to discourse on the international market, their ability to negotiate prices, and their ability to formulate rules are not strong, which has seriously affected their international competitiveness." Zhao Jungui said.
At the same time, issues such as overcapacity of basic raw material products, insufficient supply of high-end fine chemicals, and extensive development model also constrain the overall international competitiveness of the industry, Zhao Jungui said.
According to reports, under the promotion of a series of economic stimulus policies and the promotion plan of the industry by the Chinese government, the petrochemical industry in China has emerged from the impact of the financial crisis and has stabilized and recovered.
Data from the China Petroleum and Chemical Industry Federation show that in 2009, the industry's GDP increased by 0.3% year-on-year, achieving a total output value of 6.63 trillion yuan; the industry's economic operating sales revenue increased by 0.5%; fixed assets investment increased by 12.9%; petrochemical main products Yield growth.
Zhao Jungui, vice president of the China Petroleum and Chemical Industry Federation, pointed out on the 16th that China's oil and chemical industry has become a "stricken area" for international trade frictions. The Chinese petrochemical industry urgently needs to strengthen international exchanges and enhance the international discourse right and other soft powers.
