China's lead sheet is mainly used for lead content of 99.994% of 1 # electrolytic lead, casting, calendering into sheets, extruded into tubes. Second, lead is a silver-white slightly light blue metal, with high density (11.85g/cm3), good corrosion resistance, low melting point (high temperature 300 ° C - 400 ° C can be melted and welded), soft, easy to process and so on, and therefore used in many industrial fields, lead plate and lead pipe is widely used in the acid industry, storage batteries, cable wrapping and metallurgical industry equipment to play a corrosion-resistant role; lead can Absorption of radioactive rays, can be used for atomic energy industry and x, r-ray instrumentation and medical protection materials lead plate, refers to the metal lead rolled into a plate, the current common thickness of 1-10mm, more than 1 # electrolytic lead production. It can be used for ray protection, corrosion prevention, acid-resistant environment construction, sound insulation and many other aspects. General domestic production of lead plate purity of 99.99%, density of 11.34g/cm3 with a lead plate to block the rays emitted by radioactive substances, not radioactive substances. alpha particles penetration is weak, a piece of paper can be blocked; lead plate can be completely blocked to protect against α-radiation focus do not eat by mistake, staining the skin; β-rays, penetration is moderately strong, the general lead plate can be blocked by the majority of the radiation, but the Usually, when protecting β-rays, a layer of lower atomic number of the barrier to avoid bremsstrahlung radiation. γ-rays are accompanied by α and β, with a strong penetrating. A certain thickness of lead plate can block a certain proportion of the intensity of γ-rays, radioactive intensity with the thickness of the lead plate according to the exponential law of attenuation, theoretically can not be completely blocked. Completely blocking is not necessary, in fact, radioactivity is everywhere, the surrounding space are rays. As long as the control within a reasonable range can be. Shenzhen Zhengfang Industrial Materials is a professional sales of anti-radiation materials manufacturers specifically can consult customer service personnel.
