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.

According to sources from the organizers, the 8th China International Chemical Industry Exhibition will highlight the products and technologies of large companies, large companies, listed companies and SMEs. The exhibition will fully display the highest level of the industry. The total exhibition area of ​​the exhibition is expected to exceed 20,000 square meters. There will be 8 professional pavilions, including the Petroleum and Chemical Complex, Organic and Inorganic Chemical Materials, Agricultural Chemicals, Fine and Specialty Chemicals, Chemical Composite Materials and Raw Materials, Dyes and Pigments, Chemical Equipment and Automation, and Chemical Technology.
Due to the good international influence produced by the first seven International Chemical Industry Exhibitions, the overseas investment promotion work of the 8th International Chemical Industry Fair progressed smoothly. As of yesterday afternoon, Germany and Poland have already confirmed their participation in this exhibition in the form of national exhibition pavilions. Eight chemical companies in the United States, Britain, and Germany have already signed up for the show. Together with the domestic pavilions that have clearly indicated their participation in the exhibition, the exhibition area already confirmed by the exhibition has exceeded 7,000 square meters.
The organizers stated that it has been determined to hold an international forum for the development of the oil and chemical industry during the exhibition, as well as more than ten technical exchanges, trade negotiations and information release activities.
The 8th International Chemicals Show in Shanghai will highlight the products and technologies of various companies
The day before yesterday, it was learned from the China Petroleum and Chemical Industry Association that the 8th China International Chemicals Exhibition will be held in Shanghai from April 19th to April 21st.
