Abstract
The invention provides a deep blue ultraviolet-filtering quartz tube and a preparation method thereof. The deep blue ultraviolet-filtering quartz tube is prepared from high-purified quartz sand as a raw material in basic parts by weight, and also a colorant accounting for 0.4wt%-5wt% of the high-purified quartz sand; the colorant is prepared from cobalt nitrate Co(NO3)2.6H2O, copper sulfate CuSO4.5H2O, potassium nitrate KNO3, aluminum oxide Al2O3, zinc oxide ZnO and nickel oxide NiO. The deep blue ultraviolet-filtering quartz tube molded by drawing by use of an integrated tube wall coloring preparation process is good in integrated tube wall coloring homogeneity, good in toughness, high in pressure resisting capability, high in light transmittance, and coating-free; the cut-off wavelength of the quartz tube is 360-368nm, and the transmittance of the quartz tube is 66%.
