  • Surfactants are classified in common ways

    2023-04-12 16:58:02
    In synthetic detergents, builders usually play the role of softening the water hardness and improving the pH of the washing liquid, and its dosage is generally large; the dosage of additives is small, which is customarily called "small material". Builders are mostly used in washing powder, and the amount added in liquid washing is very limited, unless it is a structured liquid washing. STPP (sodium tripolyphosphate) has comprehensive performance as a water softener and is an unparalleled builder. However, since STPP is a phosphorus-containing additive, it will aggravate the eutrophication of closed water bodies to a certain extent, so it cannot be used as a green detergent surfactant.
  • The role of the surfactant is to reduce the surface tension of the ink

    2023-04-08 10:15:30
    The effect of using a surfactant is to reduce the surface tension of the ink. High-quality printing can only be obtained when the contact angle between the ink drop and the paper is greater than 140, and the lower the surface tension of the ink, the larger the contact angle.
  • Precautions when polyetheramine is used in construction

    2023-04-04 10:14:49
    Containers for amino-terminated polyethers can be made of steel, aluminum, polyethylene or polypropylene. The storage temperature should not exceed 70°C. To prevent moisture absorption and oxidation, it is recommended that the container be filled with nitrogen. We generally pack them in clean, dry, sealed, leak-free galvanized iron drums. Avoid sunlight, rain and fire sources during storage. Not subject to storage regulations for flammable liquids, but should avoid entry into ground or surface water as it is not readily biodegradable.
