随着国民经济的迅速发展,多年来沿用的玻璃性能,已不能满足现代工农业技术发展的要求。因此,探求新的采光材料,越来越引起人们的极大重视。透明玻璃钢是一种新型采光材料,它的优点很多:如强度高,比重小,导热系数小;有弹性,不怕冰雹和碰撞;能透光又能 With the rapid development of the national economy, the glass properties that have been used for many years cannot meet the requirements of modern industrial and agricultural technology development. Therefore, the search for new lighting materials has increasingly attracted people’s attention. Transparent glass steel is a new type of lighting material, and its advantages are many: such as high strength, small specific gravity, small thermal conductivity; elasticity, not afraid of hail and collision;
