  • Surfactants can be used as dyeing aids and leveling agents in textile dyeing

    2022-12-02 16:19:24
    Surfactants are a major component of detergent decontamination formulations. Except for special applications, these products are discharged into the environment after use, either directly or after treatment in sewage treatment plants. However, the anionic surfactants that are relatively difficult to biodegrade are the main ones in detergents.

    Mechanism and application of surfactants in tertiary oil recovery.
  • The research and application of flame retardants are moving towards the development direction of non-halogenated

    2022-11-28 09:59:18
    When the polymer burns, carbon formation in the condensed phase can achieve the purpose of flame retardancy. When the thickness of carbon on the surface of the material reaches 1mm, it can withstand a high temperature of 743°C without catching fire. In coatings, pentaerythritol, polyphosphate and melamine can be used as good carbonizing agent, carbonizing catalyst and blowing agent respectively. If the three are added to the coating in a certain proportion, a flame retardant coating with excellent performance can be made.

    Subtilis surfactant (Surfactin), also known as subtilis peptide, is a cyclic ester peptide produced by Bacillus subtilis. It consists of a nonapeptide linked to β-hydroxy-ω-methylmyristic acid by a cyclic depsipeptide bond, and is another well-known class of biosurfactants with antimicrobial properties. According to the amino acid sequence, Surfactin is divided into three types

    Glyphosate additives have been widely used in my country. With the increasing environmental protection requirements, low toxicity to aquatic organisms, improvement of product efficacy, different application purposes and specific market requirements, the impact on glyphosate products The research and development of dosage forms also put forward new requirements accordingly.
  • Surface active agent wastewater should adopt different treatment methods

    2022-11-21 16:22:02
    Biological degradation surfactants is a method that is more studied at present, and has been adopted by some sewage treatment plants. This method can be roughly divided into the active sludge method, anaerobic digestion method, and the method of self -purification of the soil. They all use microorganisms to use the characteristics of the surfactant as the only carbon source to complete the surface active agent to complete the surface active agent. degradation.
  • After adding the surfactant to the breeding water body

    2022-11-18 15:41:06
    In the treatment and recycling of ceramic industry wastewater such as mud and glaze wastewater, precipitants or flocculants are often added. Its role is opposite to the dispersant, which can promote the desertation and gathering of the glue system to improve the dehydration and grouting efficiency of the mud.
  • Biosurfactants with antimicrobial components

    2022-11-16 16:42:19
    During in-situ remediation, the applied biosurfactant may also be adsorbed on the soil, which may also affect the physical, chemical and biological properties of the soil.
  • Polyether amine construction site should have ventilation conditions

    2022-11-14 16:42:14
    When using amino terminated polyether, there are many aspects that need attention. We should not be careless. Only better use of the product can make it give play to its unique performance advantages and achieve good results in application. When using it, we must do a good job, pay attention to the problems that may occur, and then solve them in a timely manner.
  • Precautions for maintenance and use of polyether amine

    2022-11-11 15:02:16
    The construction process of polyether amine is very simple, as long as you master its operation steps, and then further improve it on this basis. The above introduction is expected to be helpful for your future use.
  • High molecular weight polymer surfactant

    2022-11-09 16:09:43
    In the treatment and recovery of ceramic industrial wastewater, such as slurry and glaze slurry wastewater, precipitators or flocculants are often added. Contrary to dispersant, it can promote the destabilization and aggregation of colloidal system, so as to improve the dehydration of mud and grouting efficiency.
  • What is the role of the development of environment-friendly surfactants?

    2022-11-07 14:41:53
    Before use, carefully check whether the power cord is connected and robust. The wire of the linear driver of the controller and the cigarette lighter cannot be placed on the lifting link and between the upper and lower bed frames. Frequently check to avoid power failure of the wire. In the process of application, people cannot jump on the bed surface.
  • Almost all types of organic ink pigments are treated with alkyl polyglycosides

    2022-11-04 16:29:57
    Alkyl polyglycosides contain two groups with opposite polarity or solubility. The polar part is a hydrophilic group, and the non-polar part is a hydrophobic or lipophilic group. Generally, it can be divided into non-ionic, anionic, cationic and zwitterionic types.
  • It is often necessary to modify magnesium hydroxide flame retardant in practical use

    2022-11-02 17:24:51
    When aluminum hydroxide is blended with rubber, it is difficult to form a good interface between the two, and a large amount of filling will inevitably cause great damage to the physical and mechanical properties of rubber. Li Juan et al. used ATH, chlorinated paraffins and Sb2O3 together. The inorganic flame retardant ATH can meet the higher flame retardant requirements without having to be filled with a very high fraction, and at the same time, it does not affect the physical and mechanical properties of rubber.
  • Some surfactants have good oxygenation

    2022-10-31 16:22:32
    Alkyl polyglycoside surfactant, synthesized from renewable natural fatty alcohol and glucose, is a new type of non-ionic surfactant with comprehensive performance. It has the characteristics of both common non-ionic and anionic surfactants, high surface activity, good ecological security and solubility, and is internationally recognized as the first choice of "green" functional surfactant.
  • The types and structures of surfactants and auxiliaries are closely related

    2022-10-28 16:46:27
    Defoaming effect can be divided into two types: foam breaking and foam inhibiting. The substance with foam breaking ability is called foam breaking agent. An effective defoamer should not only break the foam quickly, but also prevent the formation of foam for a long time.
  • Surfactants have excellent performance in decontamination

    2022-10-26 17:00:02
    Anionic surfactant has excellent performance in decontamination, but it is often used with non-ionic surfactant to obtain better deinking effect. Anionic surfactant has good foaming and degreasing properties, and non-ionic surfactant presents non-ionic state in aqueous solution with high stability. When nonionic surfactant and anionic surfactant are used together, the colloidal particles will be negatively charged and repel each other with the same charge, forming a stable dispersion system, which is conducive to the separation and removal of ink and fiber.
  • After adding surfactant to the aquaculture water

    2022-10-24 16:47:36
    Oxygen increasing principle of surfactant: after adding surfactant in aquaculture water, the saturation solubility of oxygen in aquaculture water can be increased. According to the hydrate formation theory and the double membrane theory, since the solubility of oxygen in water is very small, the water oxygen compound in water generally first forms at the gas-liquid interface, and then slowly diffuses from the gas phase to the liquid phase. In the water body containing surfactant, due to the solubilization of the surfactant, a large amount of oxygen is dissolved in the surfactant micelle formed in the aqueous solution.
  • Application principle of surfactant in water-based metal cleaning agent

    2022-10-21 16:53:56
    The application principle of surfactant in water-based metal cleaning agent is to weaken or offset the adhesion of oil stain on metal surface through the properties of surfactant such as wetting, penetration, emulsification, dispersion and solubilization, and accelerate the oil stain to leave the metal surface by mechanical and physical methods and enter the washing solution to be emulsified, dispersed and suspended or solubilized in micelles.
  • Surfactants are those with fixed hydrophilic and lipophilic groups

    2022-10-19 16:30:16
    Emulsifier is a kind of surfactant. Surfactants have the function of emulsification and others. The main function of surfactant is to remove stains, emulsification, solubilization, suspension aid, foaming and defoaming, sterilization, etc.
