"In the 12th Five-Year Plan period, China's phosphorus chemical industry should further adjust its industrial layout, focus on the promotion of yellow phosphorous cleaner production technology implementation program, build wet chemical and phosphoric acid recycling economy industrial chain, and actively develop low-carbon technologies and products such as energy conservation, consumption reduction, and environmental protection. Last week, at the Fourth China International Phosphorus Chemical Summit Forum and Industry Conference held in Kunming, experts from more than 100 large-scale phosphorus chemical companies at home and abroad made clear the main direction for the future. Experts suggested that during the “Twelfth Five-Year Plan†period, China should further strengthen the rational use of phosphorus resources and encourage the development of basic, large-scale phosphorus chemical products for deep processing, multi-specification, specialization, and high purification. At the same time, it will focus on the promotion of the yellow phosphorus production technology promotion program, the construction of the wet chemical phosphoric acid recycling industrial chain, the promotion of the efficient use of yellow phosphorus tail gas, phosphorus slag, and phosphorous mud, as well as the production of fluorine-containing gases and phosphogypsum during the production of wet-process phosphoric acid. The comprehensive utilization of food; development of food grade, pharmaceutical grade, toothpaste grade, special grade, electronic grade, high-purity fine phosphorus chemical high-end products. According to reports, the demonstration projects and popularization and application projects in the implementation program of the cleaner production technology in the yellow phosphorus industry mainly include five aspects: First, dry method is used as a substitute for wet dust removal, comprehensive utilization of exhaust gas is strengthened, and the comprehensive utilization of yellow phosphorus tail gas purification is accelerated. Carbon-chemicals, construction of demonstration units and promotion in the industry; second, active implementation of yellow phosphorus tail gas to make sodium formate, formic acid, and oxalic acid; third is to establish a demonstration unit for recovery and utilization of heat from molten phosphorus slag and production of high value-added building materials; The second problem of yellow phosphorus or phosphoric acid production from mud; Fifth is to adjust the industry to avoid, concentrate resources to build 3 to 5 phosphate chemical (country) ecological production base. In addition, during the “Twelfth Five-Year Plan†period, the phosphorus chemical industry will also vigorously develop wet process phosphoric acid refining technology, strengthen the comprehensive utilization of phosphogypsum and the application of a series of by-products such as fluorine and iodine recovery, and promote the use of low- and middle-grade phosphate rock. Phosphoric acid and calcium chlorophosphate methods for the production of demonstration equipment such as phosphoric acid and phosphate have been actively pursued in the industrialization of kiln-process phosphoric acid and calcium phosphate-phosphate methods, and development of such products as ammonium polyphosphate, urea phosphate, polyphosphoric acid, and hypophosphite have been actively pursued. It is reported that since the Ministry of Industry and Information Technology of the People's Republic of China has been organizing the preparation of the “Proposal for the Implementation of Clean Production Technologies for the Yellow Phosphorus Industry†every year since 2009. The application technology in the plan refers to major key common technologies that are basically mature, have application prospects, and have yet to realize industrialization. Extension technologies refer to major key common technologies that are mature, urgently needed by the industry, and need to increase efforts to expand or expand the scope of application. In the past three years, more than a dozen yellow phosphorus industry cleaner production technologies such as the yellow phosphorus tail gas deep purification and utilization technology developed by the Southwest Research and Design Institute of Chemical Industry were selected in the “Programmeâ€.
Bearings are the groundwork for auto transmission parts. Auto bearing, although is a small part, it has a close relationship with reliability, security and comfort of the whole vehicle.
Bearing has two main functions. One is that shock absorber can be rotation with the wheel to keep the steering flexible when the vehicle steering. Second, the outer ring of pressure bearing is rubber products, which keep the soft connection between body and shock absorber. That is to prevent vibration damper to the body when the road is tough.
