HC plastic mesh : Currently the recycling of waste batteries has become a problem, more and more aroused extensive attention. Early in 2006, China’s first “heavy duty batteries harmless waste of resources Chemical industry Art R & D “has passed the identification of Science and Technology Department of Liaoning Province. The technology has completely successful development of independent intellectual property rights, will promote the sound of Waste Batteries in China, into a resource and industrialization.
Our battery production and sales are rising year by year, the annual domestic consumption of about 11 billion cells. Liaoning example, its annual consumption of up to 700 million cells, some produce more than 30,000 tons of used batteries, in order to calculate 74% recyclable, recoverable by 22,200 tons of zinc, manganese dioxide, and other useful materials. But now in the country, used batteries stop resource of most research in the laboratory stage, not really a set of processes applied to industrial processing of used batteries, used batteries to make a lot of value in the waste material can not be recycled .
At the same time, used batteries free to store much of environmental pollution, through corrosion and leakage, such as its heavy metal and acid into the soil or water, other water plants or biological uptake of heavy metals from the environment through the food chain amplification , step by step in the higher organisms enrichment, and then enter the human body through the food chain, resulting in savings of some organs of chronic poisoning.
According to reports, the used batteries to handle new technology uses industrial cutting, extraction, electrolysis, replacement and other multi-channel process, the used batteries in the zinc, manganese, mercury, carbon rod and other useful components to be isolated and used for cell reproduction . According to statistics, 1 ton of used batteries can be recycled 740 kg of zinc, manganese dioxide, such as active ingredients.
By the China Academy of Engineering, HU Zhuang-qi and other experts to identify the Committee considers that, by the R & D Enterprise Co., Ltd. Liaoyang unified set of processes, procedures and reasonable, advanced technology, so that the material used batteries are recycled to achieve a good recovery results . In the process of no wastewater, recycled water is applied to all battery production, non-toxic gas emissions, the row is no small amount of solid residue from the leaching toxicity of solid waste is a harmless process. The project meets the loop ‘ Economy And saving society’s industrial policy, technology has reached the international advanced level, the proposed promoting.
Raymond chemical technology development ahead of citric acid ester non-toxic Plasticizer Safe for use
Recently the “poison” wrap aroused widespread attention, in which the plasticizer into the determination whether the toxic plastic wrap is an important basis. By the end of 2005, Raymond Chemical Technology Co., Ltd. Jiangsu After 10 years of research and realized Environmental protection Industrial production of citric acid ester plasticizer plastics, the products because of the technical indicators and international advanced standards simultaneously, in addition to satisfying domestic demand for non-toxic environmentally friendly plasticizer, the products are 40% into the U.S., Japan and Europe .
