  • The anionic surfactants in modern oil agents are mainly phosphates

    2020-01-17 10:50:54
    Anionic surfactants are mainly used in the form of sulfonates and phosphates. In the early stage, most of the antistatic agents were sulfonates. However, due to the limitations of the use of these surfactants in the oil agents, and their lubrication and antistatic properties were inferior to those of phosphates, the anionic surfactants in the modern oil agents were mainly phosphates, especially the alkyl phosphates and their salts (apk) and their ethylene oxide (EO) adducts Excellent antistatic agent and lubricant in oil agent.

    Working principle: compressed air is sent into the rubber bottle (syringe), and the rubber is pressed into the feed pipe connected with the piston chamber. When the piston is in the up stroke, the piston chamber is filled with rubber. When the piston pushes the rubber dropping needle downward, the rubber is pressed out from the needle mouth. The amount of glue dripped is determined by the distance of piston down stroke, which can be adjusted manually or controlled in software.

  • How to polymerize silicone oil defoamer with organic modified polysiloxane

    2020-01-06 15:42:27
    It is generally believed that this is the main cause of fabric yellowing or color change of cloth, and the method of acylation and etherification of primary amino group is adopted to produce modified amino silicone oil or add antioxidant in order to reduce its yellowing or color change, but it is at the cost of sacrificing the hand feeling of finished fabric. In fact, the above methods can not completely eliminate the color change of finished fabric. As we know, when the dyed fabric is shaped at high temperature, the dye molecule activity intensifies, and some dyes that are not firmly bound will be separated from the fiber heat transfer or sublimation. If the dye is not blocked when it diffuses to the outer layer (including the fabric surface and air), the color after the fabric will mainly reflect the color light of the surface dye; if it is blocked (silicone oil film formation), the dyes that have heat transfer will Concentrated on the surface of the fabric.
  • Mineral oil and cationic surfactant have soft effect

    2020-01-03 16:41:14
    Anionic surfactants have excellent performance in decontamination, but they are often combined with non-ionic surfactants to get better deinking effect. The anionic surfactants have good foaming and degreasing properties. The nonionic surfactants present nonionic state in aqueous solution and have high stability. When the non-ionic surfactant and the anionic surfactant are used together, the colloidal particles are negatively charged and repel with electricity, forming a stable dispersion system, which is conducive to the separation and removal of ink and fiber.

    The compounding and Synergistic Technology of surfactants in our country is relatively backward, so we should strengthen the research on the basis and application technology in this field. The technology of multi-functional synergism, solubilization, emulsification, dispersion and anti caking should be paid more attention. Compounding technology is also the key to promote the application of special surfactants in leather making. The results show that the emulsification, dispersion and wettability of surfactants can be improved by adding 10-6 grade special surfactants.

    2019-12-20 09:50:30
    Anionic surfactants are common soap groups in Japanese cleansers. I believe that many people often see the word "soap base" and often hear people say not to use soap base cleanser, because it is not gentle, but what is soap base? This has to start from the chemical reaction formula of making "soap": fat + alkali = soap + glycerin. Here we generally think that fat is fatty acid glyceride. In the alkaline condition, the sodium fatty acid produced by heating hydrolysis is soap.
