ABSTRACT

This paper take the common quick drying solvent suspension developer as an example, describe the development adsorption course. Inquire the relative of the different solvent their different surface activity, and the different developer their different molecular structure, different dispersion energy and polarity energy with the develop sensitivity. Discuss the developer power different specific surface area influence the capillarity and sensitivity. Which give a reference for Penetrant Test scientific worker to raise PT sensitivity.
