The rubber supply has entered a seasonal growth, but the growth rate is expected to be lower than expected. After April, the main production areas in Southeast Asia have entered a seasonal peak season of natural rubber supply for different types of machines. According to the statistics of historical data, the average monthly output of Thailand, Indonesia and Malaysia in the past eight years will show obvious seasonal growth in May, June and July, and the supply pressure is relatively large in the whole year. In the second half of the year, the overall monthly output of Tianjiao in the main producing countries is 5: the screws at the jaw will be kept above the annual average level for regular inspection. As the supply of natural rubber is greatly affected by weather factors, its fluctuation elasticity is also obvious. The author believes that in the second half of the year, in terms of the industrial attributes that affect the price of natural rubber, The change of natural rubber supply will play a decisive role. The control system of Jinan Shijin universal tensile testing machine adopts DC servo electromechanical as "Power source".
due to the increase of planting area and the improvement of weather conditions, the output of natural rubber in the main production areas of Southeast Asia may increase significantly this year compared with last year, especially in Thailand, which is likely to increase this year from last year's production reduction, which will undoubtedly increase the upward pressure on the price of natural rubber. ANRPC According to the data released on May 27, Thailand, the world's largest natural rubber producer, may increase the output of natural rubber by 8% to 1.34 million tons during the month; In 2011, the annual output is expected to increase by 3.8% to about 3.38 million tons, while in 2010, the output of natural rubber in Thailand decreased by 1.4%. The authoritative person of the International Rubber Research Organization said in June that the shortage of rubber supply may be alleviated in 2011. Due to the continuous increase of rubber cutting, the output of natural rubber is expected to increase by 5.8% to 10.9 million tons
although the global supply of natural rubber increased in 2011, the market has reached a consensus. However, it can be seen from the fact that in the first half of the year, the association of major natural rubber producing countries reduced the global natural rubber production twice that the growth of natural rubber supply in 2011 may be lower than the market expectation. On April 28 and May 26, ANRPC lowered the global output of natural rubber this year twice. The latest estimate is that the annual output of natural rubber in 2011 will increase by 4.9%, lower than the actual growth rate of 6.4% in 2010. The main reason for the organization's continuous reduction of global natural rubber production is that the main production area in southern Thailand was hit by floods at the end of March, resulting in a reduction in production of about 50000 tons. In addition, the strong La Nina climate has adversely affected the supply of natural rubber in Indonesia and the Philippines. From the impact of La Nina phenomenon on the production of natural rubber in the past two decades, the global production of natural rubber decreased significantly in the strong La Nina years of 1996/1997, 1999/2000 and 2008/2009, indicating that the strong La Nina year posed a strong threat to the production of natural rubber. Due to the threat of strong La Nina this year, weather factors still pose a great threat to the supply of natural rubber in the main producing countries in Southeast Asia in the second half of the year. Even if there is an increase in production this year, it is likely that the increase in production will be lower than expected
