  • Flame retardants are widely used in industrial fields

    2023-03-23 15:58:46
    Flame retardant, as the name suggests, is an additive used to prevent materials from being ignited and prevent the spread of fire. It is mainly designed for flame retardancy of polymer materials. Generally speaking, flame retardants mainly achieve flame retardant effects by absorbing heat, covering, and preventing suffocation of non-combustible gases. Materials treated with flame retardants can effectively prevent and delay the spread of flames when attacked by external fire sources.

  • Adsorption of surfactants on soiled and washed surfaces

    2023-02-23 16:57:06
    Adsorption of surfactants (from solution) on soiled and washed surfaces has a major impact on cleaning action. This effect is mainly due to the changes in various properties (such as mechanical properties, electrical properties and chemical properties) of the interface and surface due to adsorption.
  • Alkyl glycosides have excellent performance in stain removal

    2023-02-19 16:47:48
    The use of biosurfactants to remediate soils contaminated by hydrocarbons and crude oil is a new technology. For example, cascara produced by Pseudomonas aeruginosa removed a large amount of oil from the Alaskan gravel. VanDyke et al. found that from contaminated sand and mud, the rhamnolipids produced by Pseudomonas aeruginosa can increase the recovery of hydrocarbons by 25% to 70% and 40% to 80%, respectively. Similarly, treatment of sandy soils with biosurfactants produced by Pseudomonas aeruginosa resulted in 56% and 73% recoveries of aliphatic and aromatic hydrocarbons, respectively.
  • Flame retardant is the application of flame retardant technology in real life

    2023-02-16 17:15:59
    Flame retardant science and technology is a science developed to meet the needs of social safety in production and life, prevent fires, and protect people's lives and property.
  • Surfactant and water can form a film of certain strength

    2023-02-12 11:04:20
    The use of surfactants in the flotation of ore is to use the floating effect. Stir and blow air from the bottom of the pool, the bubbles with effective mineral powder gather on the surface, collect and defoam and concentrate, thus achieving the purpose of enrichment. The mud, sand and rocks without ore are left at the bottom of the pool and should be removed regularly.

  • Polyetheramines are highly adhesive

    2022-12-29 15:45:46
    The internal stress of concrete layout is very high, and no strong hard force layout can hinder its opening. The high strength and good adhesion of the grouting adhesive can hinder the continuous expansion of cracks, but new cracks will occur because of the necessary release of the internal stress of the concrete layout. In order to make up for this shortcoming, we need an elastic layout body to participate when we do the planning of cracking adhesive, so that the old gap has a buffer when it shortens and expands, so that it will not occur new cracks.
