Since February 2011, the rubber price has entered a bear market for up to five years, with a cumulative drop of nearly 70%. From the perspective of the product price cycle, rubber prices are in the downward channel. At present, the inventory of natural rubber has decreased, and the contradiction between rubber supply and demand has eased. From the perspective of rubber costs, there is little room for price drop. Liu Xintian, secretary-general of China Commodity Development Research Center, believes that the overall drop in natural rubber is not necessarily detrimental to the industry. Analyzing the characteristics of commodities shows that the decline of natural rubber in 2015 may be another overall integration of the natural rubber industry and is expected to become a "Later". Why is rubber falling? For this, professionals think there are three reasons. First of all, from the perspective of the product price cycle, the current rubber price is in a downward path. From the Hujiao 1509 week k-line chart, we can see that rubber prices fell from 1996 to 2001; from 2001 to 2008 in the upward cycle, after the financial crisis broke down in 2008, the complex rose again. In 2011, rubber prices have entered the downward cycle since 2011. Therefore, due to the rubber price cycle, rubber may continue to decline and innovation is low. Secondly, from the point of view of the product season, July-August is the peak season for rubber production both at home and abroad, and at the same time it is the traditional off-season seasonal demand. As a result, the overall demand for the rubber market is sluggish and prices continue to oscillate at the bottom. Again, from the perspective of the industry chain and the industry as a whole, the major downstream rubber tires demand for rubber is in short supply. In recent years, the shrinking of auto sales has directly affected the demand for rubber, and the entire industry chain has entered a low state. It is understood that from the data released by the Automobile Industry Association, the production and sales in 2011 and 2012 were both lower than 5% year-on-year. Despite the fact that it picked up in 2013 and 2014, it was still in a downturn. In recent years, the downstream tire industry has been continuously affected by the friction of international trade. It has been judged by European and American as anti-dumping, which has a negative impact on the rubber tire industry chain. Looking ahead to the rubber market, rubber prices will continue to fall in the later stages, but the decline is limited. First of all, from the inertia force of the product trend, the rubber price is at the beginning of the sixth wave in the big drop channel. From the trend point of view, the price will continue to decline, and from the perspective of the time span of the previous five waves, the downward trend will be at least Continue to the end of October and early November. Secondly, from the current supply and demand of products, the current inventory of natural rubber has decreased, and the contradiction between rubber supply and demand has eased. It is understood that as of the end of July 2015, global natural rubber stocks fell from 2,063 tons at the end of 2014 to 1,845,000 tons. Thirdly, from the perspective of the product industry chain, although there are internal and external problems in automobile tires, from the perspective of emerging markets and tire consumption, the growth of emerging automobile markets in India and factors such as the replacement of new tires will create new demand points for rubber. It also provides some support for rubber prices. Finally, from the perspective of the cost of rubber, there is currently little room for rubber prices to fall. It is understood that at the end of 2014, the director of the Agricultural Science and Technology Extension Service Center of Qiongzhong County, Hainan Province, Xiao Xiaowen stated: “The current price of dry rubber is about 11,000 yuan/ton, while the production cost of private rubber is 8,000 yuan/ton, and that of agricultural land is 12,000 yuan/year. Ton, the current price of rubber has fallen below the cost of agricultural land. "This statement has been confirmed by Dong Jingjun, the director of Hainan rubber. Liu Xintian, secretary-general of China Commodity Development Research Center, believes that China's natural rubber mainly depends on imports, and its foreign dependence is over 60%. In 2014, it depended on foreign investment as high as 80.0%. Now that domestic natural rubber prices have fallen, it is conducive to the integration of China's domestic natural rubber industry and increase domestic natural rubber self-sufficiency rate. In 2015, China's natural rubber self-sufficiency rate is expected to increase to 40%.
The internal structural design is vane, Vane Damper is more suitable for soft close. ABD vane dampers are used to dampen drives, control speed, and many other applications. The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions. Vane dampers are widely used in automobile interior decoration, household electric appliances, furniture and bathroom products, etc. Our dampers can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.

When the axis of rotation is moving, the blades that are connected to the axis of rotation rotate at the same time. The silicone oil in the oil chamber is squeezed between the blade andthe body to the back of the blade. The resistance formed by the pressure of the silicone oil to the area of the blade is the damping torque of the rotating shaft and the blade. The torque generated during rotation is determined by the oil viscosity, the pressure area of the blade and the clearance between the blade and the body.
