yh-lead-glass: Lead glass is one of my companies supply products

Lead glass is one of my companies supply products, the following introduce the basic knowledge of the lead glass.
The composition of lead glass type: RmOn - PbO - SiO2 (B2O3). Type of SiO2 (B2O3), namely, silicon oxide (boron oxide), said the network formation, is the basic unit of a glass network structure. RmOn, on behalf of alkali, alkaline earth and rare earth metal metal oxide, is to make the glass network structure change, achieve the adjustment features network modification. PbO, lead oxide, namely composition, characterized by giving glass basic characteristics. With the increase of the content of PbO, the glass density, refractive index, dispersion, dielectric constant, on the X rays, and gamma ray absorption coefficient increase performance indexes such as;Its hardness, high temperature, softening temperature, chemical stability, viscosity index decreased;The glass molding compound longer, colorant colourful, increase surface gloss, knocking sound is ringing.
As early as the warring states period in China is leaded glass. The 17th century, the British make lead crystal glass art. Later, widely used in the manufacture of optical instruments, art ware, etc.
Lead glass in the medical field is also called medical X-ray radiation protection lead glass, lead glass mainly divided into domestic lead glass and lead glass, mainly used for diagnostic X-ray machine room, CT, ECT, PET, CT and PET protection room, computer room and X-ray photography, such as the observation window on the door shield, and nuclear medicine with protective screen operation, etc.
The above is a brief introduction of lead glass, welcome to choose to cooperate with us.
