    Core tip: on February 19, the Ministry of industry and information technology announced the catalogue of advanced and applicable technologies for comprehensive utilization of industrial solid waste (Draft for comments) The catalogue covers almost all bulk solid wastes in the chemical industry Experts in the industry believe that the promotion of these advanced and applicable technologies for the comprehensive utilization of industrial solid waste will certainly play a positive role in improving the technical level of the comprehensive utilization of solid waste in the chemical industry, but it is also necessary to ensure that they are effectively implemented in the industry, significantly improve the popularity of advanced technologies, and strive to improve the relevant standard system There are 10 categories and 52 technologies in the catalogue, including 6 petrochemical and chemical industries Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: on February 19, the Ministry of industry and information technology announced the catalogue of advanced and applicable technologies for comprehensive utilization of industrial solid waste (Draft for comments) The catalogue covers almost all bulk solid wastes in the chemical industry Experts in the industry believe that the promotion of these advanced and applicable technologies for the comprehensive utilization of industrial solid waste will certainly play a positive role in improving the technical level of the comprehensive utilization of solid waste in the chemical industry, but it is also necessary to ensure that they are effectively implemented in the industry, significantly improve the popularity of advanced technologies, and strive to improve the relevant standard system The catalogue has a total of 10 categories and 52 technologies, including 6 petrochemical and chemical solid waste comprehensive utilization technologies, 4 waste rubber and plastic comprehensive utilization technologies, 6 tailings and red mud comprehensive utilization technologies, 5 coal gangue, coal-fired solid waste and industrial by-product gypsum comprehensive utilization technologies, 5 building materials and new materials industrial solid waste comprehensive utilization technologies Among them, six comprehensive utilization technologies of petrochemical and chemical solid wastes are the regeneration base oil production technology of waste lubricating oil, the complete set of biodiesel production technology of waste oil, the recycling treatment technology of acrylic acid and ester waste oil, the comprehensive utilization technology of PTA Residue resources, the production technology of tetrachloroethylene from waste carbon tetrachloride and the production technology of light calcium carbonate from alkali recovery white mud For a long time, PTA residue treatment is an internationally recognized problem At present, China's PTA production capacity has exceeded 12 million tons / year, and the residue production is about 200000 tons / year The PTA Residue resource comprehensive utilization technology of Changzhou Shenshi chemical residue treatment Co., Ltd can extract useful chemical products from PTA Residue by resource treatment It is understood that this technology can recover and treat 30000 tons of chemical residues such as benzoic acid and terephthalic acid annually In addition, about 30 tons of metal cobalt and about 60 tons of metal manganese can be extracted from the incineration ash The comprehensive economic benefit can reach 28 million yuan In addition, one production line can process 60000 tons of white mud annually, and the recovery rate can reach 100% At present, the annual output of white mud in China is close to 2 million tons If all the white mud can be recycled to prepare light calcium carbonate, the secondary pollution of white mud of nearly 2 million tons can be eliminated at least every year, and the production cost of more than 500 million yuan of calcium carbonate can be saved at the same time According to Yang zaiyin, Deputy Secretary General of gypsum building materials branch of China Building Materials Federation, the technology of producing gypsum board and other new building materials from industrial by-product gypsum mentioned in the catalogue has effectively solved the problem of secondary pollution of industrial by-product gypsum, and the promotion of this technology will help to achieve the goal of 30% comprehensive utilization rate of phosphogypsum in 2015 At present, the technology has been popularized in 33 production lines nationwide, with an annual production area of 750 million square meters of gypsum board and a comprehensive utilization of 7.5 million tons of industrial by-product gypsum Zhuang Xiangning, deputy director of quality, safety and environmental protection department of China Petroleum and Chemical Industry Federation, said that this year, the Federation will focus on tracking the comprehensive utilization technology of phosphogypsum by chemical decomposition method, promote the construction of demonstration projects, and coordinate with the government to strive for the introduction of preferential policies for the comprehensive utilization of phosphogypsum Yang zaiyin suggested that advanced technology still needs perfect standard matching Although phosphogypsum has issued national standards, it is not a mandatory standard Compared with foreign standards, the composition index is relatively small and the appraisal quota is relatively low Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
