In this paper, a new polymer process machine--- centrifugal extruder is introduced. The pressure and temperature distribution of centrifugal extruder has been studied by theoretical analysis, which is based on mathematics and experiments. The results show that the pressure and temperature Distribution can provide the processing of solid-plug conveying sufficiently and stably, which can prove the industry practicability of centrifugal extruder. Keywords: Solid-plug Conveying, Centrifugal Extruder, Polymer process, Mathematics analysis.
Electromechanical integration is the inevitable result of the development of modern science and technology, and the basic premise and the inevitable trend of modern enterprise development. The use of new technology enterprises of electromechanical integration determines the position and development prospect of the enterprise in the competition.
Large amounts of deicing agents (abbr. Deicer) were applied on road pavements for snow and ice control each year in the cold region. The traditional deicers used on pavements resulted in metallic corrosion of vehicle and serious adverse environmental impacts. By contrast, acetates and formates were more environmentally friendly and more effective. After application of new deicers, heavy binder bleeding and severe stripping problems were observed occurring together with loss of asphalt pavement stability in northen Europe and northen America. Recently the large quantities of acetate-based deicers applied each year in China, damage by the deicers similar to that observed in those wereas would also occur in China. To shed light on neglected distress by deicer and guide the best practices of deicer application, asphalt mix design and maintenance of asphalt pavement, the paper revealed the asphalt mixture performance variation corroded by deicers and corrosion mechanism using immersion tension test, aqueous solutiion test and immersion penetration test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
