Big market demand for agricultural powers The Brazilian agrochemical market is divided into two parts, the fertilizer market and the plant protection chemicals market. Fertilizer markets including nitrogen fertilizers, phosphate fertilizers, sulfur fertilizers and potash fertilizers are at a relatively mature and stable stage; the market for plant protection chemicals including fungicides, herbicides, insecticides and other major herbicides is now undergoing changes due to technological innovations. stage.
Brazil has vast farming land and the climate is suitable for agricultural development. The third and fourth quarters of the year are the farming seasons in Brazil, and the demand for agrochemicals is relatively large. During this period, the prices of agrochemicals tend to increase by 10% to 15%, depending on the logistics distribution, depending on the planting type. It depends on the type of pesticide used.
In 2009, Brazil’s agrochemical market revenue reached US$19 billion, and this market will maintain steady growth in the medium and long term.
Increase in the proportion of fertilizer consumption Frost & Sullivan believes that the following five factors are conducive to the development of the Brazilian agrochemical market. First, Brazil currently consumes 6% of the world's chemical fertilizers, and this proportion will increase further: the world will increase about 75 million food consumers each year, and the low-income people in Brazil will continue to increase their food consumption capacity. These two factors are driving Brazil's grain exports and the growth of the agrochemical market. Second, with the continuous development of the Brazilian economy, the income gap between the lower and middle-level nationals has decreased, and the new consumption model has boosted the demand for food, which in turn has led to the development of the agrochemical market. Thirdly, investments from both domestic and foreign countries are increasing. For instance, two large multinational corporations, BASF and Dupont, have increased their investment in Brazil's business, while Brazil’s domestic investment is also increasing. In 2009, the Brazilian government formulated a national fertilizer plan to reduce domestic agrochemical deficits. The Brazilian government also plans to establish partnerships with countries that have good expertise in agrochemicals, such as Russia, to obtain technology transfer. Fourth, Brazil is conducting related research on genetically modified crops to increase grain production and increase the efficiency of sugarcane ethanol fuel. The introduction of genetically modified crops has changed the type and quantity of pesticides used, requiring pesticide companies to implement product innovation strategies, which in turn will promote the innovation and diversification of the agrochemical market. Fifth, in the past few years, the Brazilian agrochemical market began its industrial integration. With the recent acquisition of Bunge Fertilizantes' domestic business by Brazilian miner Vale, the entire agrochemical market will be more concentrated.
At the same time, the Brazilian agrochemical market faces the following challenges: First, agrochemical formulators face tremendous pressure from raw material suppliers on product prices and sources of supply; secondly, the price competition among generic manufacturers makes the market for plant protection chemicals Prices are lower, and customers are more sensitive to prices. Third, as the national income of Brazilians increases, there is a growing number of objections to the use of pesticides. In addition, pests produce resistance to certain active ingredients, forcing pesticide companies to increase R&D spending. Finally, The Brazilian agrochemical market is at a mature stage and the growth rate is slowing down. This trend will continue for 5 to 7 years.
The high dependence on imports is the most serious problem facing the Brazilian agrochemical market. In addition, weak infrastructure and bureaucratic registration procedures have delayed the time to market for new products. The government's lack of support for small and medium farmer subsidies and the lack of financial credit support will limit the development of the Brazilian agrochemical market.
The competitive landscape has formed There are more than 100 companies in the Brazilian fertilizer market, of which 20 are dominant. In 2009, sales of companies with revenues exceeding US$500 million accounted for 86.2% of the total market. These companies include Binge Fertilizers, Fertilizantes Heringer, a manufacturer of nitrogen, phosphorus and potassium fertilizers, Fosfertil, a supplier of raw materials and chemicals, and Yale, a global company with approximately 600,000 tons in Brazil. / Year's NPK capacity.
The types of competitors in the Brazilian plant protection chemicals market are multinational corporations that concentrate on patented products, imitation formulation mixers and distributors, of which transnational corporations dominate this market. Market leaders include Syngenta, Bayer CropScience, Monsanto, BASF, DuPont, Dow Agro and Milenia. In 2009, the top ten companies accounted for 87.2% of Brazil's market share.
In the Brazilian agrochemical market, there are still many growth opportunities to be explored: logistics and distribution needs to be improved to increase market competitiveness; the Brazilian agrochemical market is at an advanced stage, and improved and more efficient production processes are playing a role in maintaining competitiveness. It is of vital importance that innovative companies with cost-effective advantages will become market leaders; companies that can provide logistics solutions have a competitive advantage throughout the agrochemical market; they are committed to traditional export commodities (such as soybeans) and improved. Companies that produce sugar cane will rely on Brazilian agrochemicals for higher income.
The principle of metal spinning process is to cover the processed metal blank (tube blank) on the mandrel, while the blank is pressed at the end of the mandrel by the tail, and rotates with the mandrel along the spindle, and the rotary wheel moves along the mandrel.
Generally speaking, light automatic spinning machines have structural advantages similar to ordinary lathes. However, in order to meet the requirements of the above spinning process, large spinning machines usually have the following 11 core advantages.
1. The automatic spinning machine bed, main shaft, and transmission system, rotating wheel frame, tailstock and other parts should have sufficient rigidity, and also have a heavier worktable, a thicker guide rail, and a thick wall bearing support And cabinets.
2. The horizontal and longitudinal feed mechanisms of the rotary frame are mostly driven by hydraulic transmission or a combination of mechanical and hydraulic pressure to generate sufficient spinning pressure and balance step-less speed regulation to meet process requirements.
3. Ordinary automatic spinning machines usually use one rotary wheel, but there are multiple auxiliary forming wheels (flanging wheel, curling wheel, etc.). The number of rotating wheels or rotating frame of the powerful automatic spinning machine is 2 to 3 (the general type is 2, and the cylindrical part spinning machine is mostly 2 to 3), and is symmetrical to the spindle axis. Balancing the radial force during spinning, reducing the bending deflection, deflection, and vibration of the spindle and core mold provides a prerequisite for improving the accuracy of spinning parts. This correspondingly requires the rotary wheel to have a higher horizontal (such as a special spinning machine for cylindrical parts) or a longitudinal (such as a general-purpose automatic spinning machine) synchronous feed accuracy. However, a rotary wheel is used for the light and powerful automatic spinning machine.
4. The main shaft has sufficient transmission torque and power. According to the specific process requirements, it can meet the constant torque or constant power adjustment. In addition, it is best to make the spindle speed and the longitudinal feed speed of the rotary wheel steplessly adjustable. On the one hand, it can meet the arbitrary selection requirements of the spinning process; on the other hand, it can maintain the surface rotation speed of the core mold during the spinning process. Possibility of constant feed per revolution.
