What are the types of tank trucks in dangerous goods transport vehicles?
We learned that a tank truck is a dangerous goods transport vehicle specialized in transporting chemicals, generally an AT model, which belongs to the eighth category. According to the two national standards GB13690-2009 "Classification and Marking of Commonly Used Hazardous Chemicals" and GB6944-2005 "Classification and Product Name Numbering of Dangerous Goods", chemicals are divided into nine categories according to their hazards: ① Explosives ② Compressed Gases and liquefied gases ③ flammable liquids ④ flammable solids, self-igniting articles and flammable articles in contact with moisture ⑤ oxidizing agents and organic peroxides Environmentally hazardous substances.
Then the eighth type of special vehicles for corrosive products are divided into three models, namely, tank transport semi-trailers for corrosive materials, tank transport vehicles for corrosive materials, and van transport vehicles for corrosive materials. The tank truck belongs to the semi-trailer for the transport of corrosive substances and the tank transporter for corrosive substances. It is specialized in transporting liquids with a flash point not higher than 61 degrees or vehicles for transporting flammable gases, as well as transporting stable hydrogen peroxide. or its solution (concentration greater than 60%), with a volume greater than 3 cubic tanks or tank containers.
For the main substance to be transported, the goods refer to solids or liquids that can burn human tissue and cause damage to metals and other items, and have the characteristics of visible deterioration within 4 hours of contact with the skin, or when the temperature is 55C, for No. 20 copper The appearance of the solid or liquid with a corrosion rate of 625mm/a is uniform. Such products are divided into three categories according to their chemical properties: the first category is acid corrosion products C, such as sulfuric acid, hydrochloric acid, hydrochloric acid, hydrofluoric acid, Sodium hypochlorite, phosphoric acid, sulfurous acid, corroded acid, hydroiodic acid, perchloric acid, phosphorus pentoxide, phosphorus pentafluoride; the second category is sincere corrosion products, such as sodium hydroxide, methyl lithium, lithium aluminum hydride , Sodium borohydride; the third category is other corrosion products, such as, Zinc acetate, potassium cyanide.
