Solvent oil is one of the main separation products of petroleum. It is an important organic chemical raw material and basic oil for industrial production. Isohexane belongs to alkane solvent oil. After hydrogenation process, isohexane has the characteristics of low aromatics and low sulfur. Isohexane is purified and refined on the basis of n-hexane. The content of n-hexane contained in it is very small, and even basically does not exist.
In a sense, it is a kind of green environmental protection solvent, which is mainly used to clean precision instruments, such as wire plate, mobile phone and other electronic products. As the “Apple poisoning gate” incident broke out and environmental awareness increased, isohexane began to shine. At the same time, isohexane can also replace white oil. Therefore, it is gradually popularized in the cleaning industry.
Pentane in pentane foaming agent is mainly composed of n-pentane and isopentane, and when the proportion reaches more than 99%, it can be used as styrene foaming agent and finished EPS; In addition, n-pentane can be used for foaming of building panels. When making polyurethane foaming agent, it is mainly cyclopentane, which is mainly used for foam in refrigerator door body.
Polystyrene foam board, also known as foam board and EPS board, is a white object heated by polystyrene beads containing volatile liquid blowing agents and preheated by heating. It has a structural feature of micro closed holes. It is mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicles, ships, thermal insulation, floor heating. Decoration and carving are widely used.
