More Information
Summary:The invention provides a method for testing foaming material crosslinking density based on an equilibrium swelling method. Through a crosslinking density calculating formula of Flory-Rehner formula, mass M2 of a swelling foaming material is corrected and the M2 is equal to the difference of the swelling foaming material actual mass M and the corrected mass M. The corrected mass M is calculated according to a formula of corrected mass M=(foaming material volume-unfoamed material volume)* equilibrium swelling solvent density so that the accuracy of the foaming material crosslinking density obtained by the equilibrium swelling method is greatly improved.
