According to the China Association of Automotive Engineers, the strategic alliance for lightweight automotive technology innovation was established recently. The alliance aims to reduce vehicle weight, reduce consumption, and improve safety, and strives to break through the development bottleneck of China's automotive lightweight technology.
According to reports, this affiliate plans to independently innovate for 3 to 5 years, so that China's car models to reduce their own weight 8% to 10%, the safety of the national car collision and side collision safety requirements. Commercial vehicles reduce the weight of about 300 kilograms to reach the current level of lightweighting of similar international products. At the same time, a number of lightweight generic technologies with independent intellectual property rights and significant impact on the industry have been developed and promoted to enterprises.
Chen Yilong, director of the Coalition Expert Committee, believes that the lightweighting of automobiles is an urgent need for China's energy-saving and emission-reduction strategies. At present, the domestic self-owned brand passenger cars have a self-weight that is approximately 8% to 10% higher than that of foreign cars of the same type. Commercial vehicle weights are approximately 10% to 15% higher than similar foreign cars. Taking a car as an example, if the weight of the vehicle is reduced by 100 kilograms, it will be able to drive 1 kilometer per liter of oil. The National Development and Reform Commission requires that the average fuel consumption of new passenger cars in 2010 be reduced by 15% compared with 2003. Without the development of lightweight technologies, this goal cannot be achieved.
Alluvial Gold Dressing Equipment
The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.
The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
