Zusammenfassung: | The invention discloses novel environment-friendly highly-white material bottle glass. The novel environment-friendly highly-white material bottle glass contains, by weight, 72-75% of SiO2, 1.5%-2.5%of Al2O3, 8%-12% of CaO, 1%-3% of MgO, 12%-14% of (Na2O+K2O), 1%-3% of B2O3, 0.2%-1.0% of Li2O, 0.2%-1.0% of BaO, 0.1%-0.5% of CeO2 and a proper amount of a physical decolorizing agent. According to the novel environment-friendly highly-white material bottle glass, without increasing manufacturing cost, the mechanical strength and the chemical stability of the novel environment-friendly highly-white material bottle glass are improved through changing main raw material ratio and introduction of new substances, the problems that traditional highly-white material bottle glass is fragile and proneto sodium precipitation are solved, the requirement for high-speed canning of wineries is met, meanwhile, a clarifying agent free of fluorine, arsenic and antimony is used, and the requirements for environmental protection an |
