Anti-irradiation optical glass
High absorption of high energy radiation, high lead glass and CaO-B2O2 system glass, the former can prevent gamma rays and X-ray irradiation, the latter can absorb slow neutrons and thermal neutrons, mainly used in the nuclear industry , the medical field, etc. as a shielding and peep window material.
Irradiation resistant optical glass
Under certain gamma-ray and X-ray irradiation, the transmittance in the visible region changes less. The varieties and grades are the same as the colorless optical glass, and are used to manufacture optical instruments and peep windows under high-energy irradiation.
Colored optical glass
Also known as filter glass. It has selective absorption and permeability properties for specific wavelengths in the ultraviolet, visible and infrared regions. It is classified into selective absorption type, cut-off type and neutral gray according to spectral characteristics. It is classified into ion coloring, metal colloid coloring and sulfur selenium according to the coloring mechanism. The compound coloring class 3 is mainly used to manufacture filters.
H beam have many advantages, like better mechanical performance, large section modulus, low weight and saving metal. That can make architectural structure reduce 30-40% weight; save welding and riveting work up to 25%. H beam is often used in mega-structures(such as plant, high-rise building etc. ) which require great bearing capacity and better stable section, also used in bridge, ship, hoisting and conveying machinery, equipment foundations and support.
