摘要： A screw smelting machine melts raw materials with a different chemical ratio in a mixing funnel in a feeding order to prevent the long-range diffusion of a melt, and controls outflow at a suitable speed. A centrifugal casting machine solidifies the melt with the ingredients gradient varying into a radial ingredient gradient material by a centrifugal casting style. A temperature sensor monitors temperature of an outer surface of a centrifuge cavity of the centrifugal casting machine during centrifugal casting, and transmits the temperature to a control platform. The control platform determines an optimal flow rate of the melt at an end of screw rod according to ingredient gradient of ingredient radial-gradient pipe materials and a thickness of each component gradient material required with preparation, in combination with a real-time data fed back from the temperature sensor, and feeds back to a feeding end.

摘要： An environment-friendly glass material, including components like SiO2, ZnO, alkali metal oxide and S, but does not contain Cd, wherein when the thickness of the environment-friendly glass material is 3 mm, the cutoff wavelength is above 550 nm, the transmittance at 800-850 nm is above 75%, the transmittance at 850-900 nm is above 80%, the transmittance at 900-1000 nm is above 83%, and the transmittance at 1000-2000 nm is above 85%. Through rational component design, the glass material of the present invention realizes environmental protection, UV and visible light cutoff, and high near-infrared transmittance at the same time.
