Description
Изобретение относитс к сс гавам геп- лопоглощающих стекол, которые могут быть использованы дл медико-биилоги (еских и строительных целзй.SUBSTANCE: invention relates to ss gavs of hepatoprotective glasses, which can be used for medical biilogs (large and construction felts.
Цель изобретени - повышение однородности .The purpose of the invention is to increase uniformity.
Конкретные согтавы стекол и их свойства приведены в таблицеThe specific glasses of the glasses and their properties are listed in the table.
Дл составлени шихты используют традиционные сырьевые материалы в виде однозамещенного фосфорнокислого аммони или ортофосфорной кислоты, а также оксиды или углекислые соли вход щих в состав стекла катионов или метафосфаты соответствующих элементоо.To make the mixture, traditional raw materials are used in the form of monosubstituted ammonium phosphate or orthophosphoric acid, as well as oxides or carbonic salts of cations or metaphosphates of the corresponding elements.
Стекло технодогично, легко провариваетс и осветл етс при 1100-1300°С.Glass is technologically similar, easy to boil and brighten at 1100-1300 ° C.
Издели вырабатывают методом отливки или прессованием и отжигают при 550-580°С и выдержке 2 ч.The products are produced by casting or pressing and annealed at 550-580 ° C and holding for 2 hours.
Из стекла изготавливают полированные пластины размером 30x30x2 и 40x40x2 мм, нз которых определ ют светопропускание в видимой и инфракрасной област х спектра. 8 области длин волн 350-750 нм стекло пропускает до 93% лучей, а в области ПК - не л более 10% лучей.Polished plates of 30x30x2 and 40x40x2 mm in size are made of glass, and the transmittance in the visible and infrared spectral regions is determined from them. 8 wavelength range of 350-750 nm glass transmits up to 93% of the rays, and in the PC area - not more than 10% of the rays.
Введение е состав стекла В20з в количестве 0.8-3% и щелочных оксидов в количестве 0,1-3.5 способствует гомогенизации расплава и увеличению однородности стекла .The introduction of a composition of glass B20z in the amount of 0.8-3% and alkali oxides in an amount of 0.1-3.5 contributes to the homogenization of the melt and increase the homogeneity of the glass.
Оценива однородность, используют температурный интервал сепарации порошка стекла, так как известно, чем меньше температурный интервал плотностей, тем однороднее стекло. Как показано в таблице. указанное стекло характеризуетс высокой однородностью.Evaluating the uniformity, use the temperature interval for the separation of glass powder, since it is known that the smaller the temperature range of densities, the more uniform the glass. As shown in the table. This glass is characterized by high uniformity.
Повышение однородности стекла способствует улучшению качества отжига и увеличению выхода годных стеклоизделий, что в свою очередь снижает их себестоимость.Improving the homogeneity of the glass helps to improve the quality of annealing and increase the yield of glassware, which in turn reduces their cost.
Указанное теплопоглощающее стекло может быть использовано в медико-биологических цел х в качестве защитных светофильтров , пропускающих видимые и частично ультрафиолетовые лучи и поглощающих лучи инфракрасной части спектра, в частности в фитотронах при облучении биологических обьектовThe specified heat-absorbing glass can be used for biomedical purposes as protective light filters that transmit visible and partially ultraviolet rays and absorb the rays of the infrared part of the spectrum, in particular in phytotrons when irradiated by biological objects.
