Затем получают порошок промежуточного продукта 2 обработкой промежуточного продукта 1 серной кислотой, персульфатом калия и фосфорным ангидридом, охлаждением, фильтрацией, промывкой и сушкой осадка. Полученный промежуточный продукт 2 обрабатывают концентрированной серной кислотой при пониженной температуре. В полученную суспензию добавляют перманганат калия, повышают температуру до комнатной, вводят перекись водорода. Полученный коллоидный раствор промывают, фильтруют или центрифугируют. На второй стадии получают гибридный гидрогель на основе композита из графена и углеродных нанотрубок смешиванием коллоидных растворов оксида графена и углеродных нанотрубок в объемной пропорции не менее чем 12:1, добавлением органического восстановителя - D-глюкозы и термической обработки полученной финальной смеси. На третьей стадии осуществляют лиофильную сушку гибридного гидрогеля с получением аэрогеля на основе композита из графена и углеродных нанотрубок. Полученный аэрогель дополнительно обрабатывают СВЧ-излучением в микроволновой печи. После третьей стадии дополнительно проводят стадию гидрофилизации полученного аэрогеля, обрабатывая его кипящим смешанным разбавленным раствором, содержащим 3-9 % азотной кислоты и 0,5-1,5 % перекиси водорода, при соотношении Т:Ж от 1:70 до 1:50 в течение 10-20 мин.

Title: Method and device for friction welding by rotating disk
Inventor: PATON BORYS YEVHENOVYCH
IPC: B23K20/12
Filed: 2001-12-27
Abstract: The method for friction welding by rotating disk and device for its realization can be used in different branches of machine building for execution of joint and T-welds of large length in the sheet and shell structures of aluminum, titanium or other alloys, and at welding of thermoplastic polymers. Friction welding of the butt-joint sheet parts is performed by means of the rotating disk and slider, which are displaced progressively in the direction of welding together in such a manner that the slider is located behind the disk on the surface of parts, and the disk through the slider slot is submerged into the joint of parts. The material of joint is heated by disk to the plasticized condition as a result of work of frictional forces, it is transferred into the area behind the disk, where it is forcedly removed from the disk and is pressed out. The filler material is forcedly introduced into the front area of the welding zone, this is forced against the generatrix of the disk surface and with the help of the reception chamber located in the front section of the slider, is accumulated in plasticized condition. In the area behind the disk the material of joint is formed with strengthening under conditions of pressing, to this end the generating surface of slider is executed with a groove being converged. For developing the joint, a flange is made on the disk. It provides the possibility of alloying the material of joint, formation of required radius passages of corner and joints of different thickness or strengthening of the butt joints and decrease of the joint width. Weld quality as a result of the best uniformity and density of structure is also increased, the speed of welding is increase for 2-3 times, requirements for quality of the groove preparation of the welded parts are reduced, and the range of thicknesses of parts being subjected to welding is increased.

Abstract: The invention relates to the technology for refining of grain, cake and other bulk materials. It can be used in food, meat and compound feed industry at production of mustard, sauces, mayonnaises, food additives and mixed feeds. A method of automatically controlled crushing of cake is carried out by grinding of cake in two stages, moreover, at the first stage the cake is ground by percussion-centrifugal crushing of low intensity to the size of the particles not more than 8à 10 mm in the diameter and is mixed up with separated out large particles of finished powder coming for recirculation, and at the second stage this mixture is finally ground by percussive centrifugal crushing of high intensity to the assigned state of finished powder. A quantity of recirculating component of mixture at the inlet in the disintegrator is adjusted depending on the deviation of the current fineness of finished product from the given one by displacing the adjusting shutters of separator. The dispersion ability of finished product is measured by a sensor of fineness, which is installed at the outlet of separator and is connected with actuating mechanisms of adjusting shutters of the separator through adjusting microprocessor controller. The blade rotor of the percussive centrifugal mill of low intensity rotates in vertical cylinder with perforated walls and bottom, moreover, the openings of cylinder located in staggered rows have a diameter 8à 10 mm, and into the mixing chamber of this mill, which is equipped with magnetic separator of metal admixtures, are directed following flows by gravity: at the angle of 65° to the horizon û cake after first stage of crushing, at the angle of 80° to the horizon û recirculation flow of separated large particles of the finished powder. The invention ensures the high quality of powder and the stability of output of ground products independent of the oiliness of cake and state of operating units of the mill at simultaneous reduction of specific power consumption and reduction of required production area.
