Plastic bucket has been widely used in our daily life, which has the advantages of light weight, good strength, impact resistance, corrosion resistance, non-toxic and tasteless, convenient transportation and so on. At the same time, we should pay attention to the following four categories in the transportation of dangerous goods: one category: d≤ 1.2: acetic acid (glacial acetic acid, acetic anhydride, aniline, cresol, phenol, hydrochloric acid (36. Category II: d> 1.2: formic acid, silicic acid, hydrogen bromide solution, hydrogen iodide solution, chromic acid (30%), perchloric acid (≤50%) potassium hydroxide solution, sodium hydroxide solution, nitric acid (≤55%) sulfuric acid and waste sulfuric acid. Three kinds: d≤ 1.2: propionic acid, acrylic acid, methacrylic acid, ammonia solution, formaldehyde (≤35%), furfuryl alcohol, ethylene glycol, ether, hypochlorite solution (≤ 16%), alkylphenol (including C2-C8 homologues), and four kinds: d > Such as methanol, ethanol (alcohol), propanol and butanol esters (only class II and III), such as dibutyl phosphite ketone (only class II and III), ethers (only class II and III) and aliphatic hydrocarbons (only class II and III) are transported in plastic barrels.
