摘要： Provided is a method for directly recovering lead oxide used for a lead-acid battery negative electrode from waste lead paste. The method comprises: (1) contacting waste lead paste with a barium-containing desulphurizer under desulphurization reaction conditions, and performing a solid-liquid separation on the mixture after contacting to obtain a filtrate and a filtration residue; and (2) performing a conversion reaction on the above-mentioned filtration residue at a temperature of 350-750°C so as to convert the lead-containing components in the filtration residue into lead oxide. In the method, the direct recovery of a lead oxide raw material applicable to a lead-acid battery negative electrode from waste lead paste is achieved by quantitatively replenishing a barium sulphate additive in the process of desulphuration, thereby substantially decreasing the recovery cost and energy consumption, and improving the comprehensive utilization of waste lead paste.

摘要： The present application provides a continuous preparation system and method for vinylidene chloride. In the present application, by coupling two stages of high gravity reactors, the product vinylidene chloride and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method, and the product obtained using the method has high purity. In addition, by combining steam stripping and high gravity, trichloroethane and alkali solution are rapidly mixed for mass transfer, and the product vinylidene chloride is rapidly distilled from the reaction system in form of the azeotrope (based on rapid diffusion of water vapor), such that the reaction proceeds continuously towards the direction of producing vinylidene chloride, thus significantly improving the conversion rate. As proved by a test apparatus, the present application can stabilize the purity of the vinylidene chloride product at 98% or more (mass fraction), decrease the TOC value of chloride salt wastewater to 100mg/L or less, and decrease the consumption of materials and the cost of subsequent salt-containing wastewater treatment.

摘要： The present disclosure involves a preparation method of bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite. Bio-based silica/poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) nanocomposite is environment-friendly, and silica and poly (itaconate-ter-isoprene-ter-glycidyl methacrylate) are derived from non-petroleum base materials, which do not rely on fossil fuel. Compared with nanocomposite without nanocomposite, nanocomposites with glycidyl methacrylate have better silica diffusion, mechanical properties and wet-skid resistance of rubber product are improved while consuming the same time. Further, rolling resistance is decreased so that using silane coupling agent is avoided. Therefore, the processing technology is simplified, and VOC emission is avoided. It is a kind of "green tire" rubber product.
