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.

The new model of agricultural transformation explores 46 billion to help the "sixth industry"
[ China Agricultural Machinery Industry News ] The Central Rural Work Conference, which ended on December 20, once again pointed out the direction for future agricultural development in China. The meeting proposed to further promote the structural reform of the agricultural supply side and focus on optimizing the industrial product structure. A key task of the structural reform of the agricultural supply side is to increase the income of the entire industrial chain of agriculture, to strengthen the production, to do the best, and to make the third.
The new model of agricultural transformation explores 46 billion to help the "sixth industry"
The integration and development of the agricultural one, two, and three industries is also called the “sixth industry†by researchers. Wu Xiao, director of the Department of Agriculture and Economics of the National Development and Reform Commission, said on December 8 that as agricultural production costs continue to rise, the road to extensive agricultural development relying on resources and efforts has become unsustainable, and some agricultural products have more than necessary production and structure. Sexual shortages coexist, which forces us to vigorously promote the supply-side structural reform of agriculture. The integration of rural one, two, and three industries is a good way to promote closer and more effective integration of agricultural development and market demand.
In fact, the term "sixth industry" comes from Japan, emphasizing that agricultural producers are the mainstay and is a term coined to solve the problem of Japanese agricultural income. Since 1+2+3 is equal to 6, 1×2×3 is also equal to 6, so it is called the sixth industry. In order to improve farmers' income and agricultural competitiveness, Japan, South Korea and other countries have sought to improve the agricultural industrial chain and supply chain, play a role in agricultural versatility, and develop the sixth industry to find a way to adapt to the characteristics of modern agriculture.
China officially proposed the integration of rural first, second and third industries at the national level, which originated from the Central Document No. 1 in 2015. The Ministry of Agriculture's "National Agricultural Products Processing Industry and Rural One-two-Three Industry Integration Development Plan (2016-2020)" (hereinafter referred to as "Planning"), which is led by the Ministry of Agriculture, requires coordination as an inherent requirement of industrial integration development, and strives to promote industrial cross-cutting. Convergence, and proposes that by 2020, the income from the processing of agricultural products processing enterprises above designated size will reach 26 trillion yuan, with an average annual growth rate of around 6%.
Wu Xiao said on December 8 that the National Development and Reform Commission has set up a special project for the integration of rural industries in the special construction fund. At present, it has recommended a total of more than 46 billion yuan for special construction funds, which has driven more than 400 billion yuan of social investment.
Xia Ying, a researcher at the Institute of Agricultural Economics and Development of the Chinese Academy of Agricultural Sciences, said in an interview with the Economic Observer that China's integration of the first, second and third industries is from the perspective of agriculture, allowing new businesses such as cooperatives, family farms, and large planters. The main body can play an active role, thus ensuring the interests of the peasants to a large extent. At present, the background of China's agricultural development has changed, and the reform of agricultural supply side belongs to the reform of consumers. In the previous stage of China's unresolved food and clothing problems, the agricultural product market was the seller's market; now it is the buyer's market. Under such circumstances, the supply-side reform is actually determined by the new demand orientation of consumers, and the versatility value of agriculture is increasingly exerted.
Agricultural transformation
The "Plan" proposes that the main task of industrial integration is to develop third-service industries such as deep processing of agricultural products, e-commerce, and leisure agriculture on the basis of doing well in rural industries. At the same time, the paper also pointed out the challenges of the imperfect industrial system in China's agriculture, the lack of coordination in the development of production and sales, the lag of the transformation and upgrading of agricultural products processing industry, the small number of joint-stock cooperation, and the close relationship of interests.
Wu Xiao, director of the Department of Agriculture and Economics of the National Development and Reform Commission, said that under the great logic of China's economic development entering a new normal, growth slowdown, structural adjustment, and power conversion. In recent years, regardless of the number of migrant workers, wages, and wage growth. In the continuous decline, the rate of growth of farmers' income in China continued to decline after 2011. From the international experience, Japan, South Korea and other countries have sought to improve the peasant income and agricultural competitiveness by improving the agricultural industrial chain and supply chain, giving play to the versatility of agriculture and developing the sixth industry. . In the next stage, China should effectively promote the integration of rural industries as a new situation to promote farmers' income, improve the linkage mechanism of the agricultural industry chain, and vigorously support the management of large-scale farming, family farms, farmer cooperatives, etc., promote industrial integration, and promote farmers' More share of the industry's value-added benefits.
Xia Ying told the Economic Observer that the integration of the first, second and third industries is the value of deepening agriculture and emphasizes the main position of agriculture. In the past, China’s industrialized operations were mainly processing industries at the back end of the agricultural industrial chain. In this form, the agriculture-related enterprises carry out the processing and circulation of agricultural products, thereby sharing the benefits, and promoting the development of agriculture is the secondary and tertiary industries. The benefits that farmers receive from them are actually discounted. Nowadays, China's integration is from the perspective of agriculture, allowing new business entities such as cooperatives, family farms, and large-scale farmers to play a greater role, thus ensuring the interests of farmers to a large extent. "The path of the past is from the second and third industries to agriculture. Now it is from the industry's 'one after another' to integrate development." Xia Ying said that in the main body of agricultural production, in the past, leading enterprises and agriculture-related companies have taken the lead and now encourage new types. The business entity is working as an agricultural producer.
