Aluminum rolling oil diatomite, 35% to 40% of the rolling oil. Gongyi City to Guozhen gathering area is one of the country's largest aluminum foil base band, there are plenty of solid waste every day to deal with oil diatomite. Gongyi City Xinhua Machinery Factory and scientific research units, through painstaking research, developed two patented oil diatomite oil extraction equipment, after Xichuan Alcoa, Alcoa innovation Shandong, Henan and other companies use aluminum Yeongdeungpo proposed The bar only content of about 35% to 40%. Various technical indicators have reached new oil using a standard, the amount of discharged waste oil was 2.7% up to the national standard GB4284-1084 agricultural pollutants in sludge control, allowing emissions. The device is used in all pipe connections, no waste discharge wastewater emissions, energy saving and environmental protection. Recycling aluminum foil, aluminum foil rolling oil use heavy oil pollution rolling mill due to be replaced rolling oil, 40 tons per mill a replacement, replace three times a year, to be replaced each year rolling mill 120 tons of oil, Old oil processing and spread new oil purchase of 3,500 yuan per ton, each mill in oil change cost 420,000 yuan. Gongyi City Xinhua Machinery Factory and scientific research units, developed aluminum and copper rolling oil regeneration equipment, used in the Henan Wanda, China Unicom Alcoa, Alcoa XICHUAN other units, and achieved encouraging results. These companies use the equipment, product quality significantly improved greatly reduce oil consumption, competitiveness improved significantly. The device has two patents, technology is a national initiative.
