【摘要】 根据基础原料蜡在3种添加剂的作用下合成的调和蜡的针入度拟合方程,采取分层截面的方法进行分析,分别建立了基础原料蜡的质量分数为70%,矿物蜡添加剂、合成蜡与乙烯酯共聚物添加剂质量分数和为30%时,测试温度分别为25.0,37.8,43.3℃的条件下,调和蜡针入度的分层曲面方程。通过数学模型,分析了不同添加剂对调和蜡强度的影响变化趋势。研究了基础原料蜡在加入添加剂后合成蜡的结晶过程,调和蜡的晶体与原料蜡相比,晶体出现的温度、生长方式、尺寸、形状都不相同。给出了调和蜡针入度趋势预测。更多还原

【Abstract】 As to the fitting equation of the penetration about mix wax which synthesized by raw material wax under the function of three kind of 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 additives 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.更多还原
