Aluminium sulphate is form by reacting alumina which contains in kaolin with sulphuric acid solution in a stirred reactor.Reaction occurs in variance of different time and temperature.The result of reaction is paste aluminium which will be extracted about 3 times using hot aquadest and consentration of aluminum analized by titrimetric methode.Time,
Possible seismo-ionosphere perturbations revealed by VLF signals collected on ground and on a satellite
The results of the monitoring of three VLF/LF signals collected in Petropavlovsk station (Kamchatka, Russia) and one VLF signal collected on board of the DEMETER French satellite are presented.Two periods of the seismic activity occurred in the Japan-Kamchatka area during November–December 2004 and July–September 2005 were inves
WD-YOLO: A More Accurate YOLO for Defect Detection in Weld X-ray Images
X-ray images are an important industrial non-destructive testing method.However, the contrast of some weld seam images is low, and the shapes and sizes of defects vary greatly, which makes it very difficult to detect defects in weld seams.In this paper, we propose a gray value curve enhancement (GCE) module and a model click here specifically desig
Research of the Laser Cladding and Wear-resistance of Worn Surface of Heavy Load Gear of Mining Machine
Taking the worn out tooth surface of walking gear in JOY mining machine which imported from Germany as green re-manufacture study object,the anti-wear and anti-corrosion coating without crack nor pore is successfully produced by two techniques of fatigue layer removal and laser cladding in which parameters are optimized.The bonding state of laser c
