高硼硅玻璃(又名硬质玻璃)
高硼硅玻璃(又名硬质玻璃),因线热膨胀系数为(3.3士0.1)×10-6/K,也有人称之为"硼硅玻璃3.3"。它是一种低膨胀率、耐高温、高强度、高硬度、高透光率和高化学稳定性的特殊玻璃材料,因其优异的性能,被广泛应用于太阳能、化工、医药包装、电光源、工艺饰品等行业。它的良好性能已得到世界各界的广泛认可,特别是太阳能领域应用更为广泛,德、美等发达国家已进行了较为广泛的推广。硼硅玻璃3.3的线热膨胀系数为(3.3士0.1)×10-6/K,其主要性能指标均达到国际ISO标准,与美国康宁公司的7740料,德国肖特公司的50料属同种料性。与普遍玻璃相比,无毒副作用,其机械性能,热稳定性能,抗水、抗碱、抗酸等性质大大提高,可广泛用于化工、航天、军事、家庭、医院等各个领域,可制成灯具、标盘、望远镜片,洗衣机观察孔,微波炉盘,太阳能热水器等多种产品,具有良好的推广价值和社会效益,该种玻璃在我国出现是基础材料工业的又一次新革命
High borosilicate glass (also known as hard glass) is also called
"borosilicate glass 3.3" because of its linear thermal expansion
coefficient (3.3 x 0.1)x 10-6/K. It is a kind of special glass material
with low expansion rate, high temperature resistance, high strength,
high hardness, high transmittance and high chemical stability. Because
of its excellent performance, it is widely used in solar energy,
chemical industry, pharmaceutical packaging, electric light source,
handicrafts and other industries. Its good performance has been widely
recognized by all walks of life in the world, especially in the field of
solar energy, which has been widely promoted in developed countries
such as Germany and the United States. The linear thermal expansion
coefficient of borosilicate glass 3.3 is (3.3 s 0.1)x 10-6/K. Its main
performance indexes meet the international ISO standard. It has the same
properties as the 7740 materials of Corning Company in the United
States and the 50 materials of Schott Company in Germany. Compared with
common glass, non-toxic side effects, its mechanical properties, thermal
stability, water resistance, alkali resistance, acid resistance and
other properties are greatly improved. It can be widely used in chemical
industry, aerospace, military, family, hospital and other fields. It
can be made into lamps, trays, telescopes, washing machine observation
holes, microwave oven trays, solar water heaters and so on. Many kinds
of products have good popularization value and social benefit. The
appearance of this kind of glass in our country is another new
revolution in the basic material industry
