Description
Известны способы изготовлени сетчатых фильтров из неметаллических материалов (органический материал, керамика, фарфор и др.), металлических (бронза, никель, железо, сплавы меди) и из чистых тугоплавких металлов (вольфрам, молибден, титан и т. д.) металлокерамическим путем. Эти способы имеют р д недостатков, к которым относ тс частичное пауглераживание металла при термической обработке, загр знение другими примес ми или недостаточные экономические показатели и низкое качество сеток.There are known methods for making screen filters from non-metallic materials (organic material, ceramics, porcelain, etc.), metal (bronze, nickel, iron, copper alloys) and from pure refractory metals (tungsten, molybdenum, titanium, etc.) by metal-ceramic method. . These methods have a number of drawbacks, which include partial wadding of the metal during heat treatment, contamination with other impurities or insufficient economic indicators and poor quality of the grids.
С целью интенсификации процесса и улучшени качества сетки предлагаетс способ, при котором электролиз ведут при различных услови х в зависимости от состава и толщины заготовки. Дл получ ени сетки из не поддающихс травлению металлов и сплавов (например, вольфрама, молибдена и тантала) в состав исходной заготовки ввод т другие металлы (например, цинк, кадмий и железо), которые образуют в составе сплава растворимые структурные составл ющие.In order to intensify the process and improve the quality of the mesh, a method is proposed in which electrolysis is carried out under various conditions depending on the composition and thickness of the workpiece. To obtain a mesh of metals and alloys that cannot be etched (for example, tungsten, molybdenum and tantalum), other metals (for example, zinc, cadmium and iron) that form soluble structural components in the alloy are introduced into the initial billet.
В качестве заготовки примен етс фольга (если материал поддаетс прокатке) или пластина, изготовленна металлокерамическим способом.Foil (if the material is amenable to rolling) or a plate made by a metal-ceramic method is used as a blank.
При травлении никелевой фольги толщиной 0,04 мм в качестве электролита берут раствор NH4C1 - 10 г/л. Температура раствора 20- 40°, анодна плотность тока 14 а/Ли, котодна плотность тока 90 ajdM.When etching a nickel foil with a thickness of 0.04 mm, NH4C1 solution is taken as the electrolyte - 10 g / l. The temperature of the solution is 20-40 °, the anode current density is 14 a / Li, and the current density is 90 ajdM.
При травлении фольги из нержавеющей стали толщиной 0,08- 0,13 мм электролитом вл етс 10-15%-ный раствор НСЬ Температура раствора 15-30, анодна плотность тока 5-12 .и2, катодна плотность тока 45-90 а/Лк.When etching a stainless steel foil with a thickness of 0.08-0.13 mm, the electrolyte is a 10-15% solution of HCl. The solution temperature is 15-30, the anodic current density is 5-12. And 2, the cathodic current density is 45-90 A / Lx .
Электролиз ведетс в течение 2-12 мин. Рассто ние между электродами строго определенно и не менее 70 мм. Электролит в процессе травлени перемещивают.Electrolysis is carried out for 2-12 minutes. The distance between the electrodes is strictly certain and not less than 70 mm. The electrolyte in the process of etching move.
Изготовленные фильтры представл ют собой сетку с круглыми отверсти ми диаметром от 20 до 300 мк. Пористость таких фильтров составл ет 30-50%. Варьиру режимы электролиза, можно получитьThe filters produced are a grid with round holes with a diameter of 20 to 300 microns. The porosity of such filters is 30-50%. Varying electrolysis modes, you can get
