新冠疫苗包装对药用玻璃产生巨大需求,一定程度上改变了现有中硼硅玻璃市场格局。作为药物包装的最适玻璃材料,中硼硅玻璃也由此迎来了新一轮的发展。国外中硼硅玻璃生产商德国肖特、美国康宁、日本电气硝子公司加大药用玻璃投资力度,发展势头强劲;国内通过政策引领以及在配方优化、工艺突破、设备改进、标准编制等方面的持续提升,使得中硼硅玻璃产业有了一定的进步和发展,产品已经实现出口国外。受疫情影响,中硼硅玻璃在未来仍然会持续发展,国内大部分低硼硅药用玻璃也会逐渐被中硼硅玻璃所替代,进而实现中硼硅玻璃作为医药包装材料的全面普及。 相似文献

The borosilicate glass is the most common industrial solution host barrier used for the immobilization of low-level wastes for its excellent chemical durability and mechanical properties. The borosilicate glass samples were prepared in a muffle furnace at a temperature 1300 °C, glass samples were then annealed in a furnace at 400 °C. In this study, density, microhardness, pH and the durability of borosilicate glass were tested. Many leaching solutions such as HCl, NaOH and ground water were used. The results show that the prepared glass has good microhardness. The glass composition containing 37.5 % slag ?37.5 % cement dust – 25 % B2O3 is the most durable glass in acidic solution and the borosilicate glass of the composition 37.5 % cullet – 37.5 % cement dust – 25 % B2O3 is the most corroded glass in acidic solution. The durability was also studied after subjecting the glass samples to different irradiation doses of γ- rays. Infrared absorption results were interpreted in the light of the effect of corrosion and irradiation on the vibrational bands. 相似文献

Aluminum-containing raw materials for the synthesis of aluminum-borosilicate glasses for E-glass fiber should be rationally chosen to comprehensively assess their effect on the glass melting processes. The characteristic properties of the chemical, phase, and granulometric composition of the raw materials such as metallurgical alumina, non-metallurgical alumina, disthene, and kaolin were under study. It was revealed that the type of aluminum-containing raw materials significantly influenced the rate of glass formation processes and heat consumption required for these processes. The efficiency of aluminum-containing raw materials is influenced by the following factors: the phase composition, which determines the sequence and rate of phase transformations, as well as the heat-absorbing ability of the furnace batch and glass melt. The most energy-efficient material is non-metallurgical alumina of the White Alumina brand. Using it facilitates saving energy resources for glass formation processes from 2.64% to 16.30% as compared with other types of aluminum-containing raw materials. The use of kaolin proves to be the least efficient due to the additional energy consumption for the process of destruction of the crystal structure of kaolinite, the reduced thermal conductivity of the batch, and the thermal transparency of the borosilicate glass melt. 相似文献
