200 # Solvent oil factory wholesale quality assurance

Press boiling range points, solvent oil can be divided into three categories: low boiling point solvent oil, such as 6 # solvent oil extraction, boiling range 60-90 ℃; boiling point solvent oil, such as rubber solvent oil, boiling range 80-120 ℃; high boiling point solvent oil, such as oil paint solvent boiling range of 140-200 ℃, ink solvent oil is widely used in recent years, the dry spots can be up to 300 ℃. Under normal circumstances, 60 ~ 90 ℃ called extraction solvent oil, often referred 6 # solvent oil; 80 ~ 120 ℃ called rubber solvent oil, often referred 120 # solvent oil; 140 ~ 200 ℃ say as paint solvent oil, or 200 # solvent oil. In addition, the ink solvent oil, dry-cleaning solvent oil. Sometimes, cutting each enterprise will be different boiling range. For example, 6 # solvent oil, some manufacturers of boiling ranges is 60 ~ 75 ℃, usually we call it a narrow 6 # solvent oil, in order to show the difference. According to the actual production, 120 # solvent oil distillation range tend to be controlled between 90 ~ 120 ℃. According to the chemical structure of stars, solvent oil can be divided into paraffinic, naphthenic and aromatic hydrocarbons three. In fact in addition to ethane, toluene and xylene, few outside pure hydrocarbon compound solvent oil, solvent oil is a mixture of hydrocarbons of various structures. From the chemical structure, it can be divided into paraffinic, naphthenic and aromatic hydrocarbons. Commonly referred to as 6 #, 120 #, 200 # solvent oil, it is paraffins. It refers to an aromatic hydrocarbon as benzene, toluene, xylene and the like. By zoning, in general, can be divided mainly used in the extraction of soybean oil, Levin seed oil, peanut oil, animal fat and bone extraction solvent oil, used in rubber, rubber shoes, tires and other rubber solvent oil fields, with in paints, coatings industrial paint solvent oil, and so on. In addition, the washing solvent oil, ink solvent oil. According to the national standard GB1922-88, namely its 98% distillation temperature or dry-point divide solvent oil, a common grades are: 70 # fragrant solvent oil, petroleum ether 90 #, 120 # rubber solvent oil, 190 # detergent oil, 200 # paint solvent oil, 260 # special kerosene-type solvent. There are also 6 # extraction solvent oil, aviation gasoline washing, 310 # color ink solvent oil. Farm locust solvent oil. In fact, far more than the market, the manufacturer according to user needs, production of a variety of solvent oil.
