With PVC futures officially listed in May of this year, chlor-alkali chemicals grabbed the first order to sell. Some chlor-alkali enterprises stated that in 2009 China's chlor-alkali chemical industry was subject to the dual challenges of economic weakness and depressed downstream demand. The purpose of corporate hedging was to make full use of the same principle of both the futures market and the spot market, using the time difference between futures contracts and spot business formation. The hedging mechanism to avoid and reduce the risk of production and operation caused by large price fluctuations. The hedging function of the futures market allows them to reduce the adverse effects of major raw materials and PVC products due to price fluctuations. Some companies also indicated that they would first open a hedging policy at a futures company recommended by the company, and then apply for a hedging for a non-broker member of the DCE after the time is ripe. Currently, the chloro-alkali enterprises can be seen behind the large market in the domestic futures market. They began to use this as an effective means of inventory management and adjustment of inventory.
The reporter learned from Dashang that there are many spot companies that directly use the futures market as a purchase or sales channel to seize opportunities for arbitrage. There are also many spot companies that participate in futures markets as investments. Some companies stated that hedging avoids the risk of exposure from unilateral buying and selling of the company's stock, and uses the futures market to lock in profits, ensuring that the company's unfavorable conditions in the face of the financial crisis will continue to grow steadily.
Futures industry experts have analyzed the trends of enthusiasm for the hedging of chlor-alkali chemicals, and believe that the current hedging requirements of large and medium-sized state-owned enterprises still occupy a prominent position, but more and more private enterprises and SMEs are joining the futures market. From immature to relatively mature, from a small amount of participation to gradually enlarge the scale, from a single set of protection to a variety of forms, petrochemical companies have become an important force in China's futures market. It is expected that the overall size of the futures market will multiply exponentially in the next two to three years.
KK linear module is driven by a ballscrew while a guideway slides on an optimized U-rail to achieve higher accuracy and greater stiffness.
Accessories of KK Single Axis Robot are also supported for specific demands, such as an aluminum cover, bellows, motor adaptor flange and limit switchs.
〇 Aluminum cover and bellow: contamination protection
〇 Motor adaptor flange: connection for different types of motors
〇 Limit switchs: starting point, positioning and other safety matters
(1) Multi-task design: Integrated ball screw and linear guide U-shaped track, not only provide precision linear motion, can also be matched with multi-functional accessories. It is very convenient for multi-purpose application designs, and it can also meet the needs of high-precision linear Drives.
(2) Small size and light weight: U-shaped track can be used as a guide rail, but also use the platform structure, greatly reduce the installation volume, and design the optimized structure with the finite element method to obtain the best rigidity and weight ratio. Smooth positioning movements with low torque and low inertia reduce energy consumption.
(3) High precision and high rigidity: Through the deformation analysis of the contact position of the steel ball by the load in each direction, it is known that this precision linear module has the characteristics of high precision and high rigidity. The optimal structural design is based on the finite element method to obtain the optimal rigidity and weight ratio.
(4) Easy to detect and fully equipped: positioning accuracy, positioning repeatability, running parallelism and starting torque and other functions are easy to detect.
5)Easy assembly and maintenance: No need professional assemble skill.
