00 CO 1 Изобретение относитс к составам стекол, которые могут, найти применение в качестве светофильтров дл остеклени теплиц. Обычное оконное стекло имеет наибольшее светопропускание в области 4ПО-500 нм и несколько меньшее светопропускание в интервале длин волн 600-800 нм, обусловленные присутствием в стекле оксида железа. Применение оконного стекла.дл остеклени теплиц не создает благопри тных условий дл развити растений. Растени могут нормально расти только на свету определенного спект ра состава и интенсивности, В расте ни х на свету происходит важнейший физиологический процесс - фотосинте который зависит от силы и спектраль ного состава света. Дл гармоническ го развити растений необходи м полный спектр видимой части солнечного излучени . Однако наиболее интенсив но фотосинтез происходит при красно-оранжевых лучах, слабее - при сине-фиолетовых и почти не идет при зеленых лучах. - (.Поэтому дл остеклени теплиц i необходим светофильтр, поглощающий зеленые лучи и максимально пропуска щий лучи в интервале 650-700 нм, т.е. соотношение световьтх потоков должно быть больше 1. Цель изобретени - получение теп лопоглощающего стекла нейтрального 33 тона с соотношением световых потоков - 1,1-1,25 и увеличение поглощени в инфракрасной области спектра. Конкретные составы стекол приведены в табл. 1. В табл. 2 приведены светотехнические характеристики стекол. По химической устойчивости стекло относитс к III - IV гидролитическому классу. В качестве сырьевых материалов дл варки стекла используют песок, глинозем , доломит мел, соду, поташ, окаокалину железа, металлический селен, пиролюзит или марганцевокислый калий. Варку стекла осуществл ют при тем-пературе 1430-1450°С в горюковой или ванной печах, а выработку - методом прессовани или выт гивани ленты стекла. Полученное сткло обладает высокой светопрозрачностью в видимой части спектра (66-80%), максимумом пропускани красных лучей (70-85%) в интервале 650-700 нм и высоким поглощением инфракрасных лучей (50-63%). Стекло обеспечивает требуемые дл нормального развити растений светотехнические характеристики: повышенное свётопропускани в видимой области спектра, соотношение световых потогютоков 650 равное 1,1-1,25, и увеличение поглощени инфракрасных лучей, что позвол ет использовать его ,Щ1Я остеклени теплнц. Таблица 100 CO 1 The invention relates to glass compositions which can be used as light filters for greenhouse glazing. Conventional window glass has the highest light transmission in the 4PO-500 nm region and slightly lower light transmission in the wavelength range of 600-800 nm, due to the presence of iron oxide in the glass. The use of window glass for glazing greenhouses does not create favorable conditions for the development of plants. Plants can grow normally only in the light of a certain spectrum of composition and intensity. In plants, the most important physiological process occurs in light — photosynthesis, which depends on the strength and spectral composition of light. For the harmonious development of plants, a full spectrum of visible solar radiation is needed. However, photosynthesis is most intense with red-orange rays, weaker with blue-violet and almost does not occur with green rays. - (. Therefore, for the glazing of greenhouses i, a light filter is necessary that absorbs green rays and transmits maximum rays in the range of 650–700 nm, i.e. the ratio of light fluxes must be greater than 1. The purpose of the invention is to obtain a neutral heat-absorbing glass of 33 tones the light fluxes are 1.1-1.25 and the increase in absorption in the infrared region of the spectrum.The specific glass compositions are given in Table 1. The lighting characteristics of the glasses are listed in Table 2. According to the chemical stability, glass belongs to the III-IV hydrolytic class. As raw materials for glass melting, sand, alumina, dolomite, chalk, soda, potash, iron oxide, metallic selenium, pyrolusite, or potassium permanganate are used. Glass melting is carried out at a temperature of 1430-1450 ° C in gas furnaces or baths. and production by pressing or drawing a glass ribbon. The resulting glass has a high translucency in the visible part of the spectrum (66-80%), a maximum of red rays (70-85%) in the range of 650-700 nm and a high absorption of infrared rays ( 50-63%). The glass provides the lighting characteristics required for normal plant development: increased light transmission in the visible spectral range, the ratio of light fluxes of 650 equal to 1.1-1.25, and an increase in the absorption of infrared rays, which makes it possible to use it.
