过去制备蜡壳常将配方中的松香先与干石灰单独钙化,然后再与其它物料混和的方法。我们改用松香不单独钙化,而是一次性加入的工艺制备蜡壳。以蜡壳的低温屈曲次数、粘性、抗变形等指标作了对比试验,证明两种方法所制备的蜡壳性能基本一致。某些指标比原工艺还好。由于本法省去了一道工序,工艺较为简单,值得在生产中推广应用。 In the past, wax shells were often prepared by calcining the rosin in the recipe separately from dry lime, and then mixing it with other materials. Instead of using calcification separately, we used a one-time addition process to prepare wax shells. A comparative experiment was conducted with the index of low temperature buckling, viscosity, and deformation resistance of the wax shell, which proved that the performance of the wax shell prepared by the two methods was basically the same. Some indicators are better than the original process. Due to the elimination of a process in this law, the process is relatively simple and worth promoting and applying in production.
