product name***
Product Name English Lead nitrate
Product Alias ​​Formula Pb(NO3)2
Product use for the production of lead salt, also used in medicine, printing and dyeing, matches, paints, dyes, **, tanning leather, plate making, pyrotechnics and other industrial CAS number 10099-74-8
Toxicity protection *** toxic effects on the human body, especially the nervous system, blood, blood vessels change. It has a great influence on protein metabolism, cell energy balance and cell genetic system. The lead edge appears on the edge of the gum (mainly the anterior teeth). The so-called "lead color" appears -- the skin is grayish-white, and lead in the urine is considered to be a symptom of lead. In case of acute poisoning caused by ingestion of ***, 1% to 2% magnesium sulphate solution may be used for gastric lavage and 10% sodium thiosulfate may be intravenously injected. When chronic poisoning occurs, sodium edetate may be consumed. The maximum allowable concentration of lead and inorganic lead compounds is 0.01 mg/m3, and the average working day concentration is 0.007 mg/m3. Lead vapors, nitrogen oxides, and helium are present during the production process. These substances are poisonous, the equipment should be sealed, and the production environment should be well ventilated. Masks should be worn during operation. When the concentration of lead vapor is high, filter-type gas masks should be used. Working hours prohibit eating and smoking in the workplace. Wear protective overalls and other labor protection products when working. After work, you must shower with hot water, gargle and brush your teeth before and after meals. Regular medical examinations. Give health food.
Packaging and storage use plastic woven bags or iron drums lined with polyethylene plastic bags, each bag (barrel) net weight 50kg. There should be obvious "oxidizer" and "have **" signs on the package. It is a secondary inorganic oxidant, Danger Code No. 23023. Should be stored in a cool, ventilated, dry warehouse. Package sealed, moisture-proof. Keep away from heat and fire. Do not mix and transport with organic matter, combustibles and acids. Protect from rain and sun exposure during transportation. Be careful when loading and unloading to prevent damage to the package. In the event of fire, water, sand, and carbon dioxide extinguishers can be used to save.
Physical and chemical properties of white cubic crystals or monoclinic crystals. Relative density 4.53 (20°C). Soluble in water, **, hydrazine, slightly soluble in ethanol. Insoluble **. The solubility in water is 56.5g/100g water (20°C). The dried *** was decomposed at 205-223°C, and the wet *** began to decompose at 100°C. The basic ***Pb(NO3)2·PbO was first formed, and the heating was continued to lead oxide. For strong oxidants, contact with organic matter can promote its combustion. poisonous!
