Need to know the radiation protection materials lead plate lead door lead glass barium sulfate lead clothing lead screen lead curtain Please + W X (Ray Protection Alliance) lead is gray-white metal, density 11.34, melting point 327.5 ℃, boiling point 1740 ℃, soft texture, tensile strength is small. Lead in the air by oxygen, water and carbon dioxide, its surface will quickly oxidize to generate a protective film; under heating, lead can quickly with oxygen, sulfur, halogen compounds; lead and cold hydrochloric acid, cold sulfuric acid almost does not work, can be with hot or concentrated hydrochloric acid, sulfuric acid reaction; lead and dilute nitric acid reaction, but with concentrated nitric acid does not react; lead can be slowly dissolved in strong alkaline solution. Lead and its compounds are more toxic to human body and can be accumulated in human body.
Lead is mainly used in the manufacture of lead batteries, in the acid industry and the metallurgical industry with lead plate, lead pipe lining protection equipment, electrical industry, lead used as a cable cover and fuse. Containing tin, antimony lead alloy used for printing movable type, lead-tin alloy used in the manufacture of fusible lead welding rod, lead plate and lead-plated steel used in the construction industry. Lead has good absorption of X-rays and γ-rays, and is widely used as a protective material for X-ray machines and atomic energy devices.
Lead sheet, has a strong corrosion resistance, acid and alkali resistance, acid environment construction, medical radiation protection, X-ray, CT room ray protection, weighted, soundproofing, and many other aspects, and it is a relatively inexpensive radiation protection material.? Lead plate, refers to the metal lead rolled into a plate, the common thickness of 1-20mm, commonly used specifications for the 1000 * 2000MM, the best domestic machine can produce the widest 1300MM, the longest 8000MM, more than 1 # electrolytic lead production, the market is also made of recycled lead. Its quality is slightly worse, the price difference is a little bit.
General domestic production of lead plate purity of 99.99% or more for the national standard products,? The density is 11.34g/cm3.
