单词 thixotropy
释义

Definition of thixotropy in English:

thixotropy

noun θɪkˈsɒtrəpiTHikˈsätrəpē
mass nounChemistry
  • The property of becoming less viscous when subjected to an applied stress, shown for example by some gels which become temporarily fluid when shaken or stirred.

    Example sentencesExamples
    • A professor of organic chemistry at the University of Pavia, and two colleagues from Milan offered thixotropy as an explanation.
    • Another property of muscles that increases resistance is thixotropy.
    • A very desirable property in many applications is thixotropy, in which the material behaves as a gel or very viscous liquid at rest or subject to mild shear, but flows freely when subjected to a larger shear.
    • In these cases, then, thixotropy cannot be the explanation.
    • When cold it is difficult or impossible to ‘shake out’ the stiffening due to enhanced thixotropy.

Derivatives

    Chemistry
    • Thixotropy is a property displayed by many systems, particularly those with complex molecules with long chains, familiar objects being tomato ketchup and thixotropic paint.
      Example sentencesExamples
      • This history-dependent behavior, first described for relaxed muscles by Denny-Brown in 1929, is attributed to a thixotropic effect.
      • Another advantage of the theory is that it provides a possible explanation for an important quantitative difference between the thixotropic properties of relaxed and contracting fibers, the rate of stiffness recovery.
      • Its use in stabilizer systems is advantageous because it exhibits thixotropic rheological properties, requiring little change in processing conditions while providing stability to the finished product.
      • These systems are called thixotropic and are characterized by a difference in viscosity, depending on the speed at which the shear force is applied.

Origin

1920s: from Greek thixis 'touching' + tropē 'turning'.
