What are the key points for safe use of solvent oil products

From a professional point of view, due to the composition and physical properties of solvent oil products in the field of industrial production, there will be some potential safety hazards in the use and storage process, which makes users must have a certain grasp of safety knowledge. Solvent oil. First, we need to know the boiling point and chemical properties of the product.

First of all, when the boiling point of solvent oil products is involved, the boiling point of solvent oil can be roughly calculated according to its label. For example, the boiling range of 200 solvent oil is 140-200 (?) The distillation range of 120 solvent oil is usually controlled at 90-120 (?) The distillation range of 6 solvent oil is 60-90 (?).

According to boiling range, solvent oil can be divided into three categories: low boiling point solvent oil, such as 6 extraction solvent oil, boiling range is 60-90 ℃; medium boiling point solvent oil, such as rubber solvent oil, boiling range is 80-120 ℃; high boiling point solvent oil, such as paint solvent oil, boiling range is 140-200 ℃. In recent years, the drying point of solvent oil is as high as 300 ℃. Recommended reading: what are the contents and classification of solvent oils?

Secondly, according to the chemical structure, solvent oil products can be divided into alkanes, cycloalkanes and aromatics. In fact, solvent oil is a mixture of various structural hydrocarbons, except for a small amount of pure hydrocarbon compounds such as ethane, toluene and xylene. It is also because in the use and storage of products, it is necessary to control their temperature. Upper explosion limit (V / V): 8.7, lower explosion limit (V / V): 1.1, forbidden compound: strong oxidant, the principle of using and storing strong oxide. Due to its flammability and flammability, open fire should be prohibited.

In short, in the actual emergency treatment: quickly evacuate personnel from the leakage contaminated area to the safe area, isolate and strictly restrict access. Cut off the fire. It is suggested that emergency personnel should wear self-contained positive pressure respirator and anti-static work clothes. Cut off the leakage source as much as possible.
