Solvent-based cleaners
Mar 21, 2018

    Industrial cleaning agents are generally classified as solvent-based cleaning agents and water-based cleaning agents, and are widely used in electronic hardware, machinery, packaging and printing, automotive electronics and other industries. Our article mainly explains the classification of solvent-based cleaners.
    Solvent-based cleaners are classified according to the boiling point
    Solvent-based cleaners are classified into low-boiling solvents, medium-boiling solvents and high-boiling solvents according to their boiling points. The boiling point determines the evaporation rate. Generally the boiling point below 100 is called low boiling point, evaporation speed, easy to dry, and more for active solvents or thinners. 100-150 °C boiling point leveling performance, and more for spray paint. The boiling point of 150-200°C evaporates slowly, has strong dissolving power, and has good fluidity. It is generally used as a coating. The boiling point of about 300 °C bond strength and toughness, can be used as a plasticizer and softener. Therefore, it is generally appropriate to select a solvent-based cleaning agent to select a solvent with a boiling point below 100 as much as possible.
    Solvent-based cleaners are classified according to evaporation rate
    In accordance with the evaporation rate can be divided into quick-drying and medium speed and slow dry, very slow type. The quick-drying solvents include acetone, ethyl acetate, and benzene. The medium-speed solvents include ethanol and toluene. The slow-drying solvents include butyl acetate and the like. In general, we can choose between fast and slow drying based on our products and production processes.
    Solvent-based cleaners classified by chemical composition
    Classification according to chemical composition can be divided into organic solvents and inorganic solvents. Common hydrocarbons and alcohols belong to organic solvents. Water, strong acids, molten salts and the like belong to inorganic solvents. Most organic solvents are currently on the market and can effectively solve problems such as wastewater discharge.
    Solvent-based cleaners classified by purpose
    According to the use of points can be divided into the viscosity of the blending agent, plasticizers, azeotropic mixtures, extractants, delubrication, solid solvents, impregnants, pharmaceutical solvents, carriers, etc.
