Abstract

Abstract:

　 As to the fitting equation of the penetration about mix wax which synthesized by raw material wax under the function of three kind o f chemical additives , the penetration equation with divide layers curved surface was set up by taking divide layers of sectional method. The mass fraction of raw materials basic wax is 70 %, and mineral additives, synthesis war and ethylene ester copolymer is 30 %, under the test temperature of 25. 0 , 38. 8 , 43. 3 ℃. According to the mathematical model,the change tendency of different additive s influencing mix wax was analyzed. The crystallization course of basic raw materials after acceding to the additives was studied, comparing the raw materials wax with the mix wax crystal. It appears that temperature , growth way , size and forms are all different, and gives a tendency forecasting of penetration about mix wax.
