For corrosive products, pay attention to whether the materials of the products and packaging containers will undergo chemical changes. The packaging of dangerous goods is different from the packaging of ordinary goods. There are special methods for packaging dangerous goods. Metal packaging containers should be painted on the container wall to prevent corrosive products from corroding the container. For example, the inner wall of the iron barrel for packaging synthetic fatty acids should be coated with an acid-resistant protective layer to prevent the iron barrel from being corroded by the commodity, and the commodity will also deteriorate accordingly. Another example is hydrofluoric acid, which is an inorganic acid corrosive substance. It is highly toxic and can corrode glass. Glass bottles cannot be used as packaging containers. It should be placed in metal or plastic barrels, and then in wooden boxes. Formic acid is volatile and its gas is corrosive. It should be packed in a good acid-resistant jar, glass bottle or plastic drum, sealed tightly, and then put into a solid wooden box or metal drum.
For the packaging of yellow phosphorus and other flammable commodities, it is advisable to put them in an iron drum with a wall thickness of not less than 1 mm. The inner wall of the poke must be coated with an acid-resistant protective layer. , The net weight of each barrel does not exceed 50 kg. Another example is the water bow [combustible items such as calcium carbide, which will decompose in contact with water and produce flammable acetylene gas. It should be packaged in a strong iron drum, and the drum is filled with nitrogen. If the barrel is not filled with nitrogen, a deflation piston should be installed. For flammable and explosive products, such as those with strong oxidizing properties, products that are exposed to trace impurities or rapidly decompose and explode when heated. The effective method of anti-explosive packaging is to use plastic drums, and then put the plastic drums into iron drums or wooden boxes. The net weight of each piece does not exceed 50 kg, and there should be an automatic venting safety valve. When the barrel reaches a certain gas pressure When, it can automatically deflate.
