Again, the transportation precautions of chemical raw materials are introduced

There are many kinds of chemical raw materials, which are widely used. There are 5-7 million kinds of chemicals in the world, more than 100000 kinds have been sold and circulated in the market, and more than 1000 new chemicals come out every year, of which 150-200 are considered carcinogens.

The main raw materials of inorganic chemical products are chemical minerals such as sulfur, sodium, phosphorus, potassium and calcium (see inorganic salt industry), coal, oil, natural gas, air and water. In addition, by-products and wastes from many industrial sectors are also raw materials for inorganic chemicals, such as coke oven gas in the coking production process in the iron and steel industry.

The ammonia contained in it can be recovered with sulfuric acid to make ammonium sulfate. The sulfur dioxide in the smelting waste gas of chalcopyrite, galena and sphalerite can be used to produce sulfuric acid. Dangerous goods are generally raw materials, intermediates and products of the chemical industry. The transportation method is mainly selected according to the physical and chemical properties of relevant products. If it is a production, trade or logistics enterprise.

If dangerous goods need to be transported, the MSDS (material data safety sheet) of the product must be provided first. The product is divided into three states: solid, liquid and gas. Generally, the solid state is only transported by railcars, the gaseous state is only stored by pressure cylinders or pressure tanks, and the liquid products are transported flexibly, Because it has a great relationship with temperature, it has the following choices for its transportation: General barreled rear rail car transportation with high viscosity or thermal insulation and heating tank car transportation.
