| dc.description.abstract | Automobile, essential to society, with the development of economy, the totalnumber of global automobiles grew up rapidly, in 2014 year, the total global number of automobiles more than 1.2 billion; according to estimates by IEA ,the total global number of automobiles are expected to reach 1.7 billion.However, throughout
automobiles’ life cycle end, about 75 percent of end-of -life automobiles, mainly metals, are recyclable, the 25 percent of the end-of -life automobiles are considered
waste and generally goes to landfills. And if do not properly handle the lead-acid battery of end-of-life automobiles, it would impact the environment in several ways, therefore, there are some laws about recycling of end-of-life automobiles ,In Taiwan, the lead-acid battery of end-of-life automobiles is the must be recycled item.
The scrap lead-acid battery can be divided by three parts after the disassemble process. One is lead, another is plastic and the other is acid liquid, lead and plastic can be sold as material after the process but the acid liquid just be discard after the process. So, we wants to reference the technology of acid liquid process on other country, choose the foreign technology process, make acid liquid becomes valuable and can be sold on the market.
We wants to build the acid liquid quality improvement model which consider the impurities of output and the weight loss rate and the cost of process variable, and
understand the intersection relationship between the output and the concentration by investing new technology process and new equipment. Our goal is maximum the profit of the manufacturer by providing the best selection of technology process to add the acid liquid value by impurities reduction and reduce the cost of process
variable, therefore, it would be an incentive to manufacturer to recycle and reuse the scrap acid liquid; finally, the refining heat treatment is the best selection in this thesis. | en_US |
