Hydrogen energy is a clean, efficient, safe and sustainable energy source. It is regarded as the clean energy with the most potential for development in the 21st century. Imagine that hydrogen energy can be applied to automobile fuels, not only to replace the fuel with renewable resources. And will really solve the environmental pollution problems brought by motor vehicles. This is a global energy technology revolution, and it is a super project on the living environment of all mankind. Li Wenlong, director of the special vehicle design department of China National Heavy Duty Truck Technology Center, said: "As countries pay more and more attention to environmental protection, hydrogen fuel cell technology has become one of the most important technical routes." In the No. 2 laboratory of China National Heavy Duty Truck Science and Technology Park, Li Wenlong and his team have become accustomed to the spring, summer, autumn and winter spent here. Starting from the development of hydrogen fuel cell vehicles in December 2014, The lab became their second home. Hydrogen fuel cell vehicles are completely different from traditional cars. The temperature of traditional car engines is below 70 degrees and below one hundred degrees. Normally, hydrogen fuel cell vehicles must accurately control the temperature within the range of sixty-five degrees plus or minus two degrees. To achieve this near-temperature demand, you must have a perfect temperature control system and find the key "balance point" of temperature. In the past year, Li Wenlong and his team conducted a temperature adjustment every other day. In order to get the most accurate debugging data, the most unbearable summer and winter have become the most anticipated time for the project team members. Fu Pengyue, a vehicle design engineer at the special vehicle design department of China National Heavy Duty Truck Technology Center, said: "We have deliberately selected some extreme temperature conditions for testing, so that the experimental data we have collected can more accurately reflect our Actual working conditions." In July 2017, China National Heavy Duty Truck Hydrogen Fuel Terminal tractors , bus passenger cars, and city distribution trucks have all completed prototype production. In three years, the super project implemented by Li Wenlong team is the Chinese hydrogen fuel cell vehicle field. The blanks were painted with a strong touch. With the breakthrough of new energy technologies and the support of national industrial policies, China has already taken the lead in global new energy development. China National Heavy Duty Truck's hydrogen fuel cell vehicles will build more efficient, safer, more energy-efficient green transportation and build low carbon. An environmentally friendly energy-saving society contributes to China's “hydrogen†power. 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.
