ELVAN GLASS COMPOSITION WITH FAR-INFRARED RAY EMISSION AND SURFACE HYDROPHILICITY FUNCTIONS AND ELVAN GLASS ARTICLES MANUFACTURED USING THE SAME

摘要

PURPOSE: An elvan glass composition comprising elvan that is naturally produced quartz-feldspar porphyry, and conventional soda ash glass raw materials is provided, and elvan glass articles with far-infrared ray emission and surface hydrophilicity functions manufactured from the elvan glass composition is provided. CONSTITUTION: The glass composition containing elvan with surface hydrophilicity comprises 56.81 kg of SiO2, 32 kg of Na2CO3, 7.33 kg of CaCO3, 3.18 kg of Na2B2O75H2O, 2.05 kg of NaNO3, 2.05 kg of Al(OH)3, 1.11 kg of TiO2, 1.11 kg of ZnO, 0.23 kg of Na2SiF6 and 35.3 kg of elvan, wherein the glass composition containing elvan with surface hydrophilicity reveals surface tension phenomena having a contact angle of about 4 degrees by hand lay up method.
