white or yellowish powder. Sweet. The relative density was 6.9. Melting point 820 °c. Very slightly soluble in water, insoluble in ethanol, soluble in nitric acid, hot concentrated hydrochloric acid, ammonium acetate, sodium acetate solution, partially soluble in acetic acid. Variable yellow in the sun, especially when wet. Black lead sulfide was generated when exposed to sulfide. Easy to absorb moisture. Unstable. Toxic!
lead oxide method: the lead oxide is mixed with suitable amount of water and then sent to the synthesizer, and a small amount of acetic acid is added. Under stirring, Pb:H2 S04 (92. 5) :100 ; 12.6 sulfuric acid was added for reaction, and the content was checked after 1H. The slurry was dried and crushed to obtain tribasic lead sulfate.
with the use of lead dibasic phosphite can make the plastic thermal stability and electrical insulation performance is good, and can improve the plastic weather resistance. It is mainly used as a stabilizer for PVC plastic opaque or translucent products (such as PVC cable tube, plastic sandal, loafers, yarn tube, etc.). In addition, it is also used for pigment production and the like.
packed in a barrel, iron drum or plastic woven bag lined with a polyethylene plastic film bag with a net weight of 25kg, 40kg or 50kg per barrel (bag). The package should be marked with "drug. It is an inorganic and dangerous drug. Code: 83028. Should be stored in a cool, ventilated, dry warehouse. It is not allowed to be stored and mixed with edible articles. Transport should be protected from rain and sun exposure. Storage for more than two months, the inspection content should be according to HG 2-1053-77 Article 11 after drying analysis. When there is a fire, it can be suppressed by water and sand. Protection: see lead sulfate.
